Jurors on Friday cleared Elon Musk of liability for investors’ losses in a fraud trial over his 2018 tweets falsely claiming that he had funding in place to take Tesla private.

The tweets sent the Tesla share price on a rollercoaster ride, and Musk was sued by shareholders who said the tycoon acted recklessly in an effort to squeeze investors who had bet against the company.

Jurors deliberated for barely two hours before returning to the San Francisco courtroom to say they unanimously agreed that neither Musk nor the Tesla board perpetrated fraud with the tweets and in their aftermath.

“Thank goodness, the wisdom of the people has prevailed!” tweeted Musk, who had tried but failed to get the trial moved to Texas on the grounds jurors in California would be biased against him.

“I am deeply appreciative of the jury’s unanimous finding of innocence in the Tesla 420 take-private case.”

Attorney Nicholas Porritt, who represents Glen Littleton and other investors in Tesla, had argued in court that the case was about making sure the rich and powerful have to abide by the same stock market rules as everyone else.

“Elon Musk published tweets that were false with reckless disregard as to their truth,” Porritt told the panel of nine jurors during closing arguments.

Porritt pointed to expert testimony estimating that Musk’s claim about funding, which turned out not to be true, cost investors billions of dollars overall and that Musk and the Tesla board should be made to pay damages.

But Musk attorney Alex Spiro successfully countered that the billionaire may have erred on wording in a hasty tweet, but that he did not set out to deceive anyone.

Spiro also portrayed the mercurial entrepreneur, who now owns Twitter, as having had a troubled childhood and having come to the United States as a poor youth chasing dreams.

No joke

Musk testified during three days on the witness stand that his 2018 tweet about taking Tesla private at $420 a share was no joke and that Saudi Arabia’s sovereign wealth fund was serious about helping him do it.

“To Elon Musk, if he believes it or even just thinks about it then it’s true no matter how objectively false or exaggerated it may be,” Porritt told jurors.

Tesla and its board were also to blame, because they let Musk use his Twitter account to post news about the company, Porritt argued.

The case revolved around a pair of tweets in which Musk said “funding secured” for a project to buy out the publicly traded electric automaker, then in a second tweet added that “investor support is confirmed.”

“He wrote two words ‘funding secured’ that were technically inaccurate,” Spiro said of Musk while addressing jurors.

“Whatever you think of him, this isn’t a bad tweeter trial, it’s a ‘did they prove this man committed fraud?’ trial.”

Musk did not intend to deceive anyone with the tweets and had the connections and wealth to take Tesla private, Spiro contended.

During the trial playing out in federal court in San Francisco, Spiro said that even though the tweets may have been a “reckless choice of words,” they were not fraud.

“I’m being accused of fraud; it’s outrageous,” Musk said while testifying in person.

Musk said he fired off the tweets at issue after learning of a Financial Times story about a Saudi Arabian investment fund wanting to acquire a stake in Tesla.

The trial came at a sensitive time for Musk, who has dominated the headlines for his chaotic takeover of Twitter where he has laid off more than half of the 7,500 employees and scaled down content moderation.

More than 200 years after Napoleon met defeat at Waterloo, the bones of soldiers killed on that famous battlefield continue to intrigue Belgian researchers and experts, who use them to peer back to that moment in history.

“So many bones — it’s really unique!” exclaimed one such historian, Bernard Wilkin, as he stood in front of a forensic pathologist’s table holding two skulls, three femurs and hip bones.

He was in an autopsy room in the Forensic Medicine Institute in Liege, eastern Belgium, where tests are being carried out on the skeletal remains to determine from which regions the four soldiers they belong to came from.

That in itself is a challenge.

Half a dozen European nationalities were represented in the military ranks at the Battle of Waterloo, located 20 kilometers (12 miles) south of Brussels.

That armed clash of June 18, 1815 ended Napoleon Bonaparte’s ambitions of conquering Europe to build a great empire, and resulted in the deaths of around 20,000 soldiers.

The battle has since been pored over by historians, and — with advances in the genetic, medical and scanning fields — researchers can now piece together pages of the past from the remains buried in the ground.

Some of those remains have been recovered through archeological digs, such as one last year that allowed the reconstitution of a skeleton found not far from a field hospital the British Duke of Wellington had set up.

But the remains examined by Wilkin surfaced through another route.

‘Prussians in my attic’

The historian, who works for the Belgian government’s historical archives, said he gave a conference late last year and “this middle-aged man came to see afterwards and told me, ‘Mr Wilkin, I have some Prussians in my attic'”.

Wilkin, smiling, said the man “showed me photos on his phone and told me someone had given him these bones so he can put them on exhibit… which he refused to do on ethical grounds”.

The remains stayed hidden away until the man met Wilkin, who he believed could analyze them and give them a decent resting place.

A key item of interest in the collection is a right foot with nearly all its toes — that of a “Prussian soldier” according to the middle-aged man.

“To see a foot so well preserved is pretty rare, because usually the small bones on the extremities disappear into the ground,” noted Mathilde Daumas, an anthropologist at the Universite Libre de Bruxelles who is part of the research work.

As for the attributed “Prussian” provenance, the experts are cautious.

The place it was discovered was the village of Plancenoit, where troops on the Prussian and Napoleonic sides bitterly fought, Wilkin said, holding out the possibility the remains might be those of French soldiers.

Scraps of boots and metal buckles found among the remains do point to uniforms worn by soldiers from the Germanic side arrayed against the French.

But “we know that soldiers stripped the dead for their own gear,” the historian said.

Clothes and accessories are not reliable indicators of the nationality of skeletons found on the Waterloo battlefield, he stressed.

DNA testing

More dependable, these days, are DNA tests.

Dr Philippe Boxho, a forensic pathologist working on the remains, said there were still parts of the bones that should yield DNA results, and he believed another two months of analyses should yield answers.

“As long as the subject matter is dry we can do something. Our biggest enemy is humidity, which makes everything disintegrate,” he explained.

The teeth in particular, with traces of strontium, a naturally occurring chemical element that accumulates in human bones, can point to specific regions through their geology, he said.

Wilkin said an “ideal scenario” for the research would be to find that the remains of the “three to five” soldiers examined came from both the French and Germanic sides.

The Biden administration took a first step Friday toward ending federal protections for grizzly bears in the northern Rocky Mountains, which would open the door to future hunting in Montana, Wyoming and Idaho.

The U.S. Fish and Wildlife Service said state officials provided “substantial” information that grizzlies have recovered from the threat of extinction in the regions surrounding Yellowstone and Glacier national parks.

But federal officials rejected claims by Idaho that protections should be lifted beyond those areas, and they raised concerns about new laws from the Republican-led states that could potentially harm grizzly populations.

“We will fully evaluate these and other potential threats,” said Martha Williams, director of the U.S. Fish and Wildlife Service.

Friday’s move kicks off at least a year of further study before final decisions about the Yellowstone and Glacier regions.

State officials have insisted any future hunts would be limited and not endanger the overall population.

However, Republican lawmakers in the region in recent years also adopted more aggressive policies against gray wolves, including loosened trapping rules that could lead to grizzlies being inadvertently killed.

As many as 50,000 grizzlies once roamed the western half of the U.S. They were exterminated in most of the country early last century by overhunting and trapping, and the last hunts in the northern Rockies occurred decades ago. There are now more than 2,000 bears in the Lower 48 states and much larger populations in Alaska, where hunting is allowed.

The species’ expansion in the Glacier and Yellowstone areas has led to conflicts between humans and bears, including periodic attacks on livestock and sometimes fatal maulings of humans.

Montana Gov. Greg Gianforte welcomed the administration’s announcement and said it could lead to the state reclaiming management of a species that’s been under federal protections since 1975. He said the grizzly’s recovery “represents a conservation success.”

The federal government removed protections for the Yellowstone ecosystem’s grizzlies in 2017. Wyoming and Idaho were set to allow grizzlies to be hunted when a judge restored those protections in 2018, siding with environmental groups that said delisting wasn’t based on sound science. Those groups want protections kept in place so bears can continue moving into new areas.

“We should not be ready to trust those states,” said attorney Andrea Zaccardi, of the Center for Biological Diversity.

U.S. government scientists have said the region’s grizzlies are biologically recovered but in 2021 decided that protections were still needed because of human-caused bear deaths and other pressures. Bears considered problematic are regularly killed by wildlife officials.

A decision on the states’ petitions was long overdue. Idaho Gov. Brad Little on Thursday had filed notice he intended to sue over the delay. Idaho’s petition was broader than the ones filed by Montana and sought to lift protections nationwide.

That would have included small populations of bears in portions of Idaho, Montana and Washington state, where biologists say the animals have not yet recovered to sustainable levels. It also could have prevented the return of bears to other areas such as the North Cascades region.

At a nuclear waste site in Normandy, robotic arms guided by technicians behind a protective shield maneuver a pipe that will turn radioactive chemicals into glass as France seeks to make safe the byproducts of its growing reliance on atomic power.

The fuel-cooling pools in La Hague, on the country’s northwestern tip, could be full by the end of the decade and state-owned Orano, which runs them, says the government needs to outline a long-term strategy to modernize its aging facilities no later than 2025.

While more nuclear energy can help France and other countries to reduce planet-warming emissions, environmental campaigners say it replaces one problem with another.

To seek solutions, President Emmanuel Macron, who has announced plans to build at least six new reactors by 2050, on Friday chairs the first of a series of meetings on nuclear policy that will discuss investments and waste recycling.

“We can’t have a responsible nuclear policy without taking into account the handling of used fuel and waste. It’s a subject we can’t sweep under the rug,” a government adviser told Reuters, speaking on condition of anonymity.

“We have real skills and a real technological advantage, especially over the United States. Russia is the only other country that is able to do what France does in terms of treatment and recycling.”

La Hague is the country’s sole site able to process and partially recycle used nuclear fuel.

France historically has relied on nuclear power for around 70% of its energy, although the share is likely to have fallen last year as the nuclear fleet suffered repeated outages.

Since the launch of the site at La Hague in 1976, it has treated nearly 40,000 tons of radioactive material and recycled some into nuclear fuel that can be reused. The waste that cannot be recycled is mixed with hardening slices of glass and buried for short-term storage underground.

But its four existing cooling pools for spent fuel rods and recycled fuel that has been reused risk saturation by 2030, according to French power giant EDF, which runs France’s 56-strong fleet of reactors, the world’s second biggest after the United States.

Should saturation happen, France’s reactors would have nowhere to place their spent fuel and would have to shut down — a worst-case scenario that led France’s Court of Audit to designate La Hague as “an important vulnerability point” in 2019.

Cool pools and deep clay

EDF is hurrying to build an extra refrigerated pool at La Hague, at a cost of $1.37 billion, to store spent nuclear fuel — a first step before the waste can be treated — but that will not be ready until 2034 at the earliest.

Meanwhile, France’s national agency for managing nuclear waste last month requested approval for a project to store permanently high-level radioactive waste.

The plan, called Cigéo, would involve placing the waste 500 meters below ground in a clay formation in eastern France.

Construction is expected in 2027 if it gets approval. Among those opposed to it are residents of the nearby village of Bure and anti-nuclear campaigners.

Jean-Christophe Varin, deputy director of the La Hague site, told Reuters Orano could be flexible to ensure more recycling is done at the facility and there were “several possible scenarios.”

However, he said they could not be worked on in detail in the absence of a strategic vision. Orano, for which EDF accounts for 95% of its recycling business, says it needs clear direction from the government no later than 2025, to give it time to plan the necessary investments.

The costs are likely to be high. Just keeping up with current operations at La Hague costs nearly $330 million a year.

Options EDF and Orano are considering include finding a way to recycle the used fuel more than once, but critics say the recycling itself creates more radioactive waste and is not a long-term solution. For now, the backup plan is to fit more fuel containers into the existing pools.

After being cooled in a pool for about seven years, used nuclear fuel is separated into non-recyclable leftovers that are turned into glass (4% of the material), plutonium (1%) to create a new nuclear fuel called MOX, on which around 40% of France’s reactors can run, and reprocessed uranium (95%).

The uranium in the past was sent to Russia for reenrichment and return for use in some EDF reactors, but EDF stopped doing that in 2013 as it was too costly.

In spite of the war in Ukraine, which has made many in the West avoid doing business with Russia, EDF is expected to resume sending uranium to Russia this year as the only country able to process it. It declined to confirm to Reuters it would do so.

The facility at La Hague, with its 1980s-era buildings and Star Wars-style control rooms, has its limitations.

“If we had to process MOX fuel in large quantities, the facility today isn’t adapted for it,” Varin said. “For multicycle recycling, the technology is not the same, so the modernization or replacement of installations” would require “significant” investments, he said.

Australia’s drugs watchdog on Friday announced that psychedelic substances MDMA and psilocybin — more commonly known as ecstasy and magic mushrooms — will soon be used in the treatment of depression and post-traumatic stress.

Psychiatrists will be able to prescribe the two substances from July, the Therapeutic Goods Administration said after finding “sufficient evidence for potential benefits in certain patients.”

The two drugs are currently “prohibited substances” and can only be used in closely controlled clinical trials.

The administration said they had been found to be “relatively safe” when administered in a medical setting and provided an “altered state of consciousness” that could help patients.

Mike Musker, a mental health and suicide prevention researcher at the University of South Australia, welcomed the move as “long-awaited.”

“There are many people in the community experiencing PTSD (post-traumatic stress disorder) and depression, particularly army veterans and people who have worked in emergency services, where standard psychiatric drugs have not worked and offer no relief,” he said.

Musker said the two drugs “reduce inhibitions” and could help people process difficult images and memories.

For now, the use of MDMA and psilocybin will be limited to the treatment of depression and post-traumatic stress.

But advocates hope to one day use them for alcohol dependence, obsessive compulsive disorder and eating disorders.

Psychedelics have been used by Indigenous peoples for millennia, but Western researchers only started seriously looking into their potential uses in the middle of the last century.

The drugs became symbols of the counterculture movement of the 1960s and were banned.

Authorities in Canada and the United States are among those who have already permitted the medical use of MDMA and psilocybin.

U.S. health officials said Thursday a company is recalling its over-the-counter eye drops that have been linked to an outbreak of drug-resistant infections.

The Centers for Disease Control and Prevention this week sent a health alert to doctors, saying the outbreak included at least 55 people in 12 states. One died and at least five others had permanent vision loss.

The infections, including some found in blood, urine and lungs, were linked to EzriCare Artificial Tears. Many said they had used the product, which is a lubricant used to treat irritation and dryness.

The eye drops are sold under the name EzriCare and are made in India by Global Pharma Healthcare. The Food and Drug Administration said the company recalled unexpired lots of EzriCare Artificial Tears and another product, Delsam Pharma’s Artificial Tears.

The FDA recommended the recall based on manufacturing problems including lack of testing and proper controls on packaging. The agency also blocked import into the United States.

The infections were caused by a bacteria called Pseudomonas aeruginosa. Investigators detected it in open EzriCare bottles, but further testing was underway.

EzriCare, the company that markets the eye drops in the U.S., said it is not aware of any evidence definitively linking the outbreak to the product, but that it has stopped distributing the eye drops. It also has a notice on its website urging consumers to stop using the product.

Infections were diagnosed in patients in California, Colorado, Connecticut, Florida, New Jersey, New Mexico, New York, Nevada, Texas, Utah, Washington and Wisconsin. A person in Washington died with a blood infection.

The outbreak is considered particularly worrisome because the bacteria driving it are resistant to standard antibiotics.

Investigators found the bacteria were not susceptible to any antibiotics routinely tested at public health laboratories. However, a newer antibiotic named cefiderocol seemed to work.

How could eye drops cause infections in the blood or lungs? The eye connects to the nasal cavity through the tear ducts. Bacteria can move from the nasal cavity into the lungs. Also, bacteria in these parts of the body can seed infections at other sites such as in the blood or wounds, CDC officials said.

Excitement around ChatGPT — an easy to use AI chatbot that can deliver an essay or computer code upon request and within seconds — has sent schools into panic and turned Big Tech green with envy.

The potential impact of ChatGPT on society remains complicated and unclear even as its creator Wednesday announced a paid subscription version in the United States.

Here is a closer look at what ChatGPT is (and is not):

Is this a turning point?  

It is entirely possible that November’s release of ChatGPT by California company OpenAI will be remembered as a turning point in introducing a new wave of artificial intelligence to the wider public.  

What is less clear is whether ChatGPT is actually a breakthrough with some critics calling it a brilliant PR move that helped OpenAI score billions of dollars in investments from Microsoft.

Yann LeCun, Chief AI Scientist at Meta and professor at New York University, believes “ChatGPT is not a particularly interesting scientific advance,” calling the app a “flashy demo” built by talented engineers.

LeCun, speaking to the Big Technology Podcast, said ChatGPT is void of “any internal model of the world” and is merely churning “one word after another” based on inputs and patterns found on the internet.

“When working with these AI models, you have to remember that they’re slot machines, not calculators,” warned Haomiao Huang of Kleiner Perkins, the Silicon Valley venture capital firm.

“Every time you ask a question and pull the arm, you get an answer that could be marvelous… or not… The failures can be extremely unpredictable,” Huang wrote in Ars Technica, the tech news website.

Just like Google

ChatGPT is powered by an AI language model that is nearly three years old — OpenAI’s GPT-3 — and the chatbot only uses a part of its capability.  

The true revolution is the humanlike chat, said Jason Davis, research professor at Syracuse University.

“It’s familiar, it’s conversational and guess what? It’s kind of like putting in a Google search request,” he said.

ChatGPT’s rockstar-like success even shocked its creators at OpenAI, which received billions in new financing from Microsoft in January.

“Given the magnitude of the economic impact we expect here, more gradual is better,” OpenAI CEO Sam Altman said in an interview to StrictlyVC, a newsletter.

“We put GPT-3 out almost three years ago… so the incremental update from that to ChatGPT, I felt like should have been predictable and I want to do more introspection on why I was sort of miscalibrated on that,” he said.

The risk, Altman added, was startling the public and policymakers and on Tuesday his company unveiled a tool for detecting text generated by AI amid concerns from teachers that students may rely on artificial intelligence to do their homework.

What now?

From lawyers to speechwriters, from coders to journalists, everyone is waiting breathlessly to feel disruption caused by ChatGPT. OpenAI just launched a paid version of the chatbot – $20 per month for an improved and faster service.

For now, officially, the first significant application of OpenAI’s tech will be for Microsoft software products.  

Though details are scarce, most assume that ChatGPT-like capabilities will turn up on the Bing search engine and in the Office suite.

“Think about Microsoft Word. I don’t have to write an essay or an article, I just have to tell Microsoft Word what I wanted to write with a prompt,” said Davis.

He believes influencers on TikTok and Twitter will be the earliest adopters of this so-called generative AI since going viral requires huge amounts of content and ChatGPT can take care of that in no time.

This of course raises the specter of disinformation and spamming carried out at an industrial scale.  

For now, Davis said the reach of ChatGPT is very limited by computing power, but once this is ramped up, the opportunities and potential dangers will grow exponentially.

And much like the ever imminent arrival of self-driving cars that never quite happens, experts disagree on whether that is a question of months or years.

Ridicule

LeCun said Meta and Google have refrained from releasing AI as potent as ChatGPT out of fear of ridicule and backlash.

Quieter releases of language-based bots – like Meta’s Blenderbot or Microsoft’s Tay for example – were quickly shown capable of generating racist or inappropriate content.

Tech giants have to think hard before releasing something “that is going to spew nonsense” and disappoint, he said.

A legendary U.S. groundhog, from the (east central U.S.) town of Punxsutawney, Pennsylvania, was pulled from his burrow early Thursday, with local officials declaring he saw his shadow, indicating, according to legend, there will be at least six more weeks of winter.

The annual observance of Groundhog Day on February 2 brings thousands of revelers to the town—located about 105 kilometers northeast of Pittsburgh—each year. Local officials, dressed in top hats and long coats, make a show of pulling the famous groundhog Punxsutawney Phil from his underground burrow to get his forecast.

The event is held shortly after dawn, around 7:15am, but the festivities begin as early as early as 3:30am with live entertainment and fireworks.

According to the organizer’s website, the tradition of seeking a weather forecast from a groundhog—a large rodent and member of the squirrel family—began in the town in 1886. Its origins go back to both Christian and pagan observances in Europe.

The pagan ritual marked the halfway point between the winter solstice and spring equinox. In Christian tradition, the feast day of Candlemas was when the church would distribute candles needed for the rest of winter, and it evolved into a prediction for how much longer winter would last.

Historians say the Germans began the tradition of involving an animal to the prediction process, using a hedgehog, a small, spiny animal common in parts of Europe. Germans immigrating to the eastern United States, where there are no hedgehogs, kept up the tradition by turning to groundhogs.

While the tradition and the celebration that accompanies it has stood the test of time, the groundhog has not had a good track record of accurately predicting winter weather. The U.S. National Oceanic and Atmospheric Administration (NOAA), reports Punxsutawney Phil has been right roughly 40% of the time over the last 10 years.

Some information for this report was provided by the Associated Press.

Personal possession of a small amount of hard drugs is now legal in the Canadian province of British Columbia. The controversial move is intended to reduce deaths from drug use.

The personal possession of 2.5 grams of hard drugs, including cocaine, crack cocaine, heroin, fentanyl, methamphetamine and morphine, has now been decriminalized. This temporary exemption means a person found with a small quantity of these drugs will not have them seized nor face arrest or any criminal charges. 

An average of six people a day die in British Columbia from illicit drug use, mostly men in their private residences. 

The day the three-year pilot program went into effect, the provincial coroner announced 2,272 people had died in 2022 from drug overdose. That was the second highest on record, topped only by 2,306 deaths in 2021. 

It is hoped decriminalizing small-scale possession will help fight drug mortality by putting the focus on treatment instead of criminal prosecution. 

Retired police officer Chuck Doucette, president of the Drug Prevention Network of Canada, is strongly opposed to the move, and said that “it really doesn’t address the issues at all, it’s not going to save any lives.” 

He pointed to the number of deaths by overdose and added that with drugs, “Whether they’re legal or decriminalized or not — doesn’t make them any less likely to kill you.” 

Kora DeBeck, a research scientist at the BC Center on Substance Use in Vancouver and an associate professor in the School of Public Policy at Simon Fraser University, backs decriminalization. She said that research shows prohibition does not work, but compassionate treatment of drug-dependent people can work. 

“We see so many signals that that improves our ability to connect with people who use drugs — to connect them with supports and services and things to reduce harm to them, and to their community,” DeBeck said.  

She added that decriminalization had already happened to a large extent nationwide, with the Royal Canadian Mounted Police and other law enforcement agencies already not arresting anyone found with a small amount of narcotics. 

Constable Tania Visintin of the Vancouver Police Department says the difference now is that any small amount drugs found will not be seized. 

“We were legally bound to seize those drugs, even if it was a small amount, and we would seize them for destruction. So they would never be part of any kind of charge or court case at all,” Visintin said. “But now under this new exemption, then, we just won’t be seizing any drugs that we find that are in a small personal use possession type of form.” 

For DeBeck, the benefit of this is that those addicted to drugs won’t be compelled to go to extraordinary lengths to replenish their supply. Before, said DeBeck, if their drugs were seized, “they may go to a less reliable source.”

DeBeck said that it placed people “in a desperate situation, they may have to resort to risky income generation or criminal activity or something like that.” 

The exemption, which has the blessing of the government of Prime Minister Justin Trudeau, will last for three years and is limited to British Columbia for now.

For thousands of years, ancient Egyptians mummified their dead in the search for eternal life. Now, researchers have used chemistry and an unusual collection of jars to figure out how they did it.

Their study, published Wednesday in the journal Nature, is based on a rare archaeological find: An embalming workshop with a trove of pottery around 2,500 years old. Many jars from the site were still inscribed with instructions like “to wash” or “to put on his head.”

By matching the writing on the outside of the vessels with the chemical traces inside, researchers uncovered new details about the “recipes” that helped preserve bodies for thousands of years.

“It’s like a time machine, really,” said Joann Fletcher, an archaeologist at University of York who was not involved with the study. “It’s allowed us to not quite see over the shoulders of the ancient embalmers, but probably as close as we’ll ever get.”

Those recipes showed that embalmers had deep knowledge about what substances would help preserve their dead, said Fletcher, whose partner was a co-author on the study. And they included materials from far-flung parts of the world — meaning Egyptians went to great lengths to make their mummies “as perfect as they could possibly be.”

The workshop — uncovered in 2016 by study author Ramadan Hussein, who passed away last year — is located in the famous burial grounds of Saqqara. Parts of it sit above the surface, but a shaft stretches down to an embalming room and burial chamber underground, where the jars were discovered.

It was in rooms like these where the last phase of the process took place, said Salima Ikram, an Egyptologist at The American University in Cairo who was not involved with the study. After drying out the body with salts, which probably took place above ground, embalmers would then take the bodies below.

“This was the last phase of your transformation where the secret rites, the religious rites, were being performed,” Ikram said. “People would be chanting spells and hymns while you were being wrapped and resin was being anointed all over your body.”

Experts already had some clues about what substances were used in those final steps, mainly from testing individual mummies and looking at written texts. But a lot of gaps remained, said senior author Philipp Stockhammer, an archaeologist at Ludwig Maximilian University in Germany.

The new finds helped crack the case.

Take the word “antiu,” which shows up in a lot of Egyptian texts but didn’t have a direct translation, Stockhammer said. In the new study, scientists found that several jars labeled as “antiu” contained a mixture of different substances — including animal fat, cedar oil and juniper resin.

These substances, along with others found in the jars, have key properties that would help preserve the mummies, said lead author Maxime Rageot, an archaeologist at Germany’s University of Tubingen.

Plant oils — which were used to protect the liver and treat the bandages — could ward off bacteria and fungi, while also improving the smell. Hard materials like beeswax, used on the stomach and skin, could help keep out water and seal the pores.

Some of the substances came from very far away — like dammar and elemi, types of resin that come from the tropical rainforests of Southeast Asia. These results show that ancient Egyptians would trade far and wide to get the most effective materials, the authors said.

“It’s interesting to see the complexity,” Stockhammer said. “Having this global network on the one hand, having all this chemical knowledge on the other side.”

Ikram said an important next step for the research will be to test different parts of actual mummies to see if the same substances show up. And these recipes probably weren’t universal — they changed over time and varied between workshops.

Still, the study gives a basis for understanding the past, and can bring us closer to people who lived long ago, she said.

“The ancient Egyptians have been separated from us through time and space, yet we still have this connection,” Ikram said. “Human beings all throughout history have been scared of death.”

Australian authorities on Wednesday found a radioactive capsule smaller than a coin that was lost in the vast Outback after nearly a week-long search along a 1,400 kilometers (870 miles) stretch of highway, officials said. 

The Caesium-137 capsule was discovered when a vehicle travelling at 70 kms per hour equipped with specialist detection equipment picked up the radiation, according to officials from the state of Western Australia. 

The search team then used portable detection equipment to find the capsule, which was located about 2 meters from the side of the road, they added. 

“I do want to emphasize this is an extraordinary result,” Western Australia’s Emergency Services Minister Stephen Dawson said in a news conference. 

“When you consider the scope of the research area, locating this object was a monumental challenge, the search groups have quite literally found the needle in the haystack,” Dawson said. 

The military was verifying the capsule and it would be taken to a secure facility in the city of Perth on Thursday, he added. Officials from Western Australia’s emergency response department, defense authorities, radiation specialists and others have been combing a stretch of highway for the tiny capsule that was lost in transit more than two weeks ago. 

The radioactive capsule was part of a gauge used to measure the density of iron ore feed from Rio Tinto’s Gudai-Darri mine in the state’s remote Kimberley region. The ore was being taken to a facility in the suburbs of Perth – a distance longer than the length of Great Britain. 

Officials said the capsule apparently fell off a truck and landed on the side of the road, adding that it was unlikely there will be contamination in the area. 

The silver capsule, 6 mm in diameter and 8 mm long, contains Caesium-137 which emits radiation equal to 10 X-rays per hour. People had been told to stay at least five meters (16.5 feet) away from the capsule if they spotted it, because exposure could cause radiation burns or radiation sickness. However, driving past it was believed to be relatively low risk, akin to taking an X-ray. 

Western Australia’s Chief Health Officer Andrew Robertson said the capsule was found in a remote area far from any community and it was unlikely anyone had been exposed to radiation. 

He said there would be an investigation and prosecutions would be considered under state radiation safety laws from 1975. The maximum penalty for failing to safely handle radioactive substances is $780 and $35 per day the offence continues, though the state government said on Wednesday it was considering a change to laws to allow for bigger penalties.

Boeing bid farewell to an icon on Tuesday, delivering its final 747 jumbo jet as thousands of workers who helped build the planes over the past 55 years looked on. 

Since its first flight in 1969, the giant yet graceful 747 has served as a cargo plane, a commercial aircraft capable of carrying nearly 500 passengers, a transport for NASA’s space shuttles, and the Air Force One presidential aircraft. It revolutionized travel, connecting international cities that had never before had direct routes and helping democratize passenger flight. 

But over about the past 15 years, Boeing and its European rival Airbus have introduced more profitable and fuel efficient wide-body planes, with only two engines to maintain instead of the 747’s four. The final plane is the 1,574th built by Boeing in the Puget Sound region of Washington state. 

Thousands of workers joined Boeing and other industry executives from around the world — as well as actor and pilot John Travolta, who has flown 747s — Tuesday for a ceremony in the company’s massive factory north of Seattle, marking the delivery of the last one to cargo carrier Atlas Air. 

“If you love this business, you’ve been dreading this moment,” said longtime aviation analyst Richard Aboulafia. “Nobody wants a four-engine airliner anymore, but that doesn’t erase the tremendous contribution the aircraft made to the development of the industry or its remarkable legacy.” 

Boeing set out to build the 747 after losing a contract for a huge military transport, the C-5A. The idea was to take advantage of the new engines developed for the transport — high-bypass turbofan engines, which burned less fuel by passing air around the engine core, enabling a farther flight range — and to use them for a newly imagined civilian aircraft. 

It took more than 50,000 Boeing workers less than 16 months to churn out the first 747 — a Herculean effort that earned them the nickname “The Incredibles.” The jumbo jet’s production required the construction of a massive factory in Everett, north of Seattle — the world’s largest building by volume. The factory wasn’t even completed when the first planes were finished. 

Among those in attendance was Desi Evans, 92, who joined Boeing at its factory in Renton, south of Seattle, in 1957 and went on to spend 38 years at the company before retiring. One day in 1967, his boss told him he’d be joining the 747 program in Everett — the next morning. 

“They told me, ‘Wear rubber boots, a hard hat and dress warm, because it’s a sea of mud,'” Evans recalled. “And it was — they were getting ready for the erection of the factory.” 

He was assigned as a supervisor to help figure out how the interior of the passenger cabin would be installed and later oversaw crews that worked on sealing and painting the planes. 

“When that very first 747 rolled out, it was an incredible time,” he said as he stood before the last plane, parked outside the factory. “You felt elated — like you’re making history. You’re part of something big, and it’s still big, even if this is the last one.” 

The plane’s fuselage was 225 feet (68.5 meters) long and the tail stood as tall as a six-story building. The plane’s design included a second deck extending from the cockpit back over the first third of the plane, giving it a distinctive hump and inspiring a nickname, the Whale. More romantically, the 747 became known as the Queen of the Skies. 

Some airlines turned the second deck into a first-class cocktail lounge, while even the lower deck sometimes featured lounges or even a piano bar. One decommissioned 747, originally built for Singapore Airlines in 1976, has been converted into a 33-room hotel near the airport in Stockholm. 

“It was the first big carrier, the first widebody, so it set a new standard for airlines to figure out what to do with it, and how to fill it,” said Guillaume de Syon, a history professor at Pennsylvania’s Albright College who specializes in aviation and mobility. “It became the essence of mass air travel: You couldn’t fill it with people paying full price, so you need to lower prices to get people onboard. It contributed to what happened in the late 1970s with the deregulation of air travel.” 

The first 747 entered service in 1970 on Pan Am’s New York-London route, and its timing was terrible, Aboulafia said. It debuted shortly before the oil crisis of 1973, amid a recession that saw Boeing’s employment fall from 100,800 employees in 1967 to a low of 38,690 in April 1971. The “Boeing bust” was infamously marked by a billboard near the Seattle-Tacoma International Airport that read, “Will the last person leaving SEATTLE — Turn out the lights.” 

An updated model — the 747-400 series — arrived in the late 1980s and had much better timing, coinciding with the Asian economic boom of the early 1990s, Aboulafia said. He took a Cathay Pacific 747 from Los Angeles to Hong Kong as a twentysomething backpacker in 1991. 

“Even people like me could go see Asia,” Aboulafia said. “Before, you had to stop for fuel in Alaska or Hawaii and it cost a lot more. This was a straight shot — and reasonably priced.” 

Delta was the last U.S. airline to use the 747 for passenger flights, which ended in 2017, although some other international carriers continue to fly it, including the German airline Lufthansa. 

Lufthansa CEO Carsten Spohr recalled traveling in a 747 as a young exchange student and said that when he realized he’d be traveling to the West Coast of the U.S. for Tuesday’s event, there was only one way to go: riding first-class in the nose of a Lufthansa 747 from Frankfurt to San Francisco. He promised the crowd Lufthansa would keep flying the 747 for many years to come. 

“We just love the airplane,” he said. 

Atlas Air ordered four 747-8 freighters early last year, with the final one — emblazoned with an image of Joe Sutter, the engineer who oversaw the 747’s original design team — delivered Tuesday. Atlas CEO John Dietrich called the 747 the greatest air freighter, thanks in part to its unique capacity to load through the nose cone.

The dodo bird isn’t coming back anytime soon. Nor is the woolly mammoth. But a company working on technologies to bring back extinct species has attracted more investors, while other scientists are skeptical such feats are possible or a good idea. 

Colossal Biosciences first announced its ambitious plan to revive the woolly mammoth two years ago, and on Tuesday said it wanted to bring back the dodo bird, too. 

“The dodo is a symbol of man-made extinction,” said Ben Lamm, a serial entrepreneur and co-founder and CEO of Colossal. The company has formed a division to focus on bird-related genetic technologies. 

The last dodo, a flightless bird about the size of a turkey, was killed in 1681 on the island of Mauritius in the Indian Ocean. 

The Dallas company, which launched in 2021, also announced Tuesday it had raised an additional $150 million in funding. To date, it has raised $225 million from wide-ranging investors that include United States Innovative Technology Fund, Breyer Capital and In-Q-Tel, the CIA’s venture capital firm that invests in technology. 

The prospect of bringing back the dodo isn’t expected to directly make money, Lamm said. But the genetic tools and equipment that the company develops to try to do it may have other uses, including for human health care, he said. 

For example, Colossal is now testing tools to tweak several parts of the genome simultaneously. It’s also working on technologies for what is sometimes called an “artificial womb,” he said. 

The dodo’s closest living relative is the Nicobar pigeon, said Beth Shapiro, a molecular biologist on Colossal’s scientific advisory board, who has been studying the dodo for two decades. Shapiro is paid by the Howard Hughes Medical Institute, which also supports The Associated Press’ Health and Science Department. 

Her team plans to study DNA differences between the Nicobar pigeon and the dodo to understand “what are the genes that really make a dodo a dodo,” she said. 

The team may then attempt to edit Nicobar pigeon cells to make them resemble dodo cells. It may be possible to put the tweaked cells into developing eggs of other birds, such as pigeons or chickens, to create offspring that may in turn naturally produce dodo eggs, Shapiro said. The concept is still in an early theoretical stage for dodos. 

Because animals are a product of both their genetics and their environment — which has changed dramatically since the 1600s — Shapiro said that “it’s not possible to recreate a 100% identical copy of something that’s gone.” 

Other scientists wonder if it’s even advisable to try, and question whether “de-extinction” diverts attention and money away from efforts to save species still on Earth. 

“There’s a real hazard in saying that if we destroy nature, we can just put it back together again — because we can’t,” said Duke University ecologist Stuart Pimm, who has no connection to Colossal. 

“And where on Earth would you put a woolly mammoth, other than in a cage?” asked Pimm, who noted that the ecosystems where mammoths lived disappeared long ago.

The maker of ChatGPT is trying to curb its reputation as a freewheeling cheating machine with a new tool that can help teachers detect if a student or artificial intelligence wrote that homework.

The new AI Text Classifier launched Tuesday by OpenAI follows a weeks-long discussion at schools and colleges over fears that ChatGPT’s ability to write just about anything on command could fuel academic dishonesty and hinder learning.

OpenAI cautions that its new tool – like others already available – is not foolproof. The method for detecting AI-written text “is imperfect and it will be wrong sometimes,” said Jan Leike, head of OpenAI’s alignment team tasked to make its systems safer.

“Because of that, it shouldn’t be solely relied upon when making decisions,” Leike said.

Teenagers and college students were among the millions of people who began experimenting with ChatGPT after it launched November 30 as a free application on OpenAI’s website. And while many found ways to use it creatively and harmlessly, the ease with which it could answer take-home test questions and assist with other assignments sparked a panic among some educators.

By the time schools opened for the new year, New York City, Los Angeles and other big public school districts began to block its use in classrooms and on school devices.

The Seattle Public Schools district initially blocked ChatGPT on all school devices in December but then opened access to educators who want to use it as a teaching tool, said Tim Robinson, the district spokesman.

“We can’t afford to ignore it,” Robinson said.

The district is also discussing possibly expanding the use of ChatGPT into classrooms to let teachers use it to train students to be better critical thinkers and to let students use the application as a “personal tutor” or to help generate new ideas when working on an assignment, Robinson said.

School districts around the country say they are seeing the conversation around ChatGPT evolve quickly.

“The initial reaction was ‘OMG, how are we going to stem the tide of all the cheating that will happen with ChatGPT,'” said Devin Page, a technology specialist with the Calvert County Public School District in Maryland. Now there is a growing realization that “this is the future” and blocking it is not the solution, he said.

“I think we would be naïve if we were not aware of the dangers this tool poses, but we also would fail to serve our students if we ban them and us from using it for all its potential power,” said Page, who thinks districts like his own will eventually unblock ChatGPT, especially once the company’s detection service is in place.

OpenAI emphasized the limitations of its detection tool in a blog post Tuesday, but said that in addition to deterring plagiarism, it could help to detect automated disinformation campaigns and other misuse of AI to mimic humans.

The longer a passage of text, the better the tool is at detecting if an AI or human wrote something. Type in any text — a college admissions essay, or a literary analysis of Ralph Ellison’s “Invisible Man” — and the tool will label it as either “very unlikely, unlikely, unclear if it is, possibly, or likely” AI-generated.

But much like ChatGPT itself, which was trained on a huge trove of digitized books, newspapers and online writings but often confidently spits out falsehoods or nonsense, it’s not easy to interpret how it came up with a result.

“We don’t fundamentally know what kind of pattern it pays attention to, or how it works internally,” Leike said. “There’s really not much we could say at this point about how the classifier actually works.”

“Like many other technologies, it may be that one district decides that it’s inappropriate for use in their classrooms,” said OpenAI policy researcher Lama Ahmad. “We don’t really push them one way or another.”

China says it is “deeply concerned” over reports that the United States is moving to further restrict sales of American technology to Huawei, a tech company that U.S. officials have long singled out as a threat to national security for its alleged support of Beijing’s espionage efforts.

As first reported by the Financial Times, the U.S. Department of Commerce has informed American firms that it will no longer issue licenses for technology exports to Huawei, thereby isolating the Shenzen-based company from supplies it needs to make its products.

The White House and Commerce Department have not responded to VOA’s request for confirmation of the reports. But observers say the move may be the latest tactic in the Biden administration’s geoeconomics strategy as it comes under increasing Republican pressure to outcompete China. 

The crackdown on Chinese companies began under the Trump administration, which in 2019 added Huawei to an export blacklist but made exceptions for some American firms, including Qualcomm and Intel, to provide non-5G technology licenses.

Since taking office in 2021, President Joe Biden has taken an even more aggressive stance than his predecessor, Donald Trump. Now the Biden administration appears to be heading toward a total ban on all tech exports to Huawei, said Sam Howell, who researches quantum information science at the Center for a New American Security’s Technology and National Security program.

“These new restrictions from what we understand so far would include items below the 5G level,” she told VOA. “So 4G items, Wi-Fi 6 and [Wi-Fi] 7, artificial intelligence, high performance computing and cloud capabilities as well.”

Should the Commerce Department follow through with the ban, there will likely be pushback from U.S. companies whose revenues will be directly affected, Howell said. Currently Intel and Qualcomm still sell chips used in laptops and phones manufactured by Huawei.

Huawei and Beijing have denied that they are a threat to other countries’ national security. Foreign ministry spokesperson Mao Ning accused Washington of “overstretching the concept of national security and abusing state power” to suppress Chinese competitors.

“Such practices are contrary to the principles of market economy” and are “blatant technological hegemony,” Mao said. 

Outcompeting Chinese tech

The latest U.S. move on Huawei is part of a U.S. effort to outcompete China in the cutting-edge technology sector.

In October, Biden imposed sweeping restrictions on providing advanced semiconductors and chipmaking equipment to Chinese companies, seeking to maintain dominance particularly on the most advanced chips. His administration is rallying allies behind the effort, including the Netherlands, Japan, South Korea and Taiwan – home to leading companies that play key roles in the industry’s supply chain.

U.S. officials say export restrictions on chips are necessary because China can use semiconductors to advance their military systems, including weapons of mass destruction, and commit human rights abuses. 

The October restrictions follow the CHIPS and Science Act of 2022, which Biden signed into law in August and that restricts companies receiving U.S. subsidies from investing in and expanding cutting-edge chipmaking facilities in China. It also provides $52 billion to strengthen the domestic semiconductor industry.

Beijing has invested heavily in its own semiconductor sector, with plans to invest $1.4 trillion in advanced technologies in a bid to achieve 70% self-sufficiency in semiconductors by 2025. 

TikTok a target

TikTok, a social media application owned by the Chinese company ByteDance that has built a massive following especially among American youth, is also under U.S. lawmakers’ scrutiny due to suspicion that it could be used as a tool of Chinese foreign espionage or influence.

CEO Shou Zi Chew is scheduled to appear before the House Energy and Commerce Committee on March 23 to testify about TikTok’s “consumer privacy and data security practices, the platforms’ impact on kids, and their relationship with the Chinese Communist Party.”

Lawmakers are divided on whether to ban or allow the popular app, which has been downloaded onto about 100 million U.S. smartphones, or force its sale to an American buyer.

Earlier in January, Congress set up the House Select Committee on China, tasked with dealing with legislation to combat the dangers of a rising China.
