Month: April 2023

Scientists said Monday they have developed the first mobile printer that can produce thumbnail-sized patches able to deliver mRNA COVID-19 vaccines, hoping the tabletop device will help immunize people in remote regions.

While many hurdles remain and the 3D printer is likely years away from becoming available, experts hailed the “exciting” finding.

The device prints 2-centimeter-wide patches that each contain hundreds of tiny needles that administer a vaccine when pressed against the skin.

These “microneedle patches” offer a range of advantages over traditional jabs in the arm, including that they can be self-administered, are relatively painless, could be more palatable to the vaccine-hesitant and can be stored at room temperature for long periods of time.

The popular mRNA COVID-19 vaccines from Pfizer and Moderna need to be refrigerated, which has caused distribution complications — particularly in developing countries that have condemned the unequal distribution of doses during the pandemic.

The new printer was tested with the Pfizer and Moderna jabs, according to a study in the journal Nature Biotechnology, but the goal of the international team of researchers behind it is for it to be adapted to whatever vaccines are needed.

Robert Langer, co-founder of Moderna and one of the study’s authors, told AFP that he hoped the printer could be used for “the next COVID, or whatever crisis occurs.” 

Ana Jaklenec, a study author also from the Massachusetts Institute of Technology, said the printer could be sent to areas such as refugee camps or remote villages to “quickly immunize the local population,” in the event of a fresh outbreak of a disease like Ebola.

Vacuum-sealed

Microneedle patch vaccines are already under development for COVID-19 and a range of other diseases, including polio, measles and rubella.

But the patches have long struggled to take off because producing them is an expensive, laborious process often involving large machines for centrifugation. 

To shrink that process down, the researchers used a vacuum chamber to suck the printer “ink” into the bottom of their patch molds, so it reaches the points of the tiny needles.

The vaccine ink is made up of lipid nanoparticles containing mRNA vaccine molecules, as well as a polymer similar to sugar water.

Once allowed to dry, the patches can be stored at room temperature for at least six months, the study found. The patches even survived a month at a balmy 37 degrees Celsius (99 Fahrenheit).

Mice that were given a vaccine patch produced a similar level of antibody response to others immunized via a traditional injection, the study said.

The printed patches are currently being tested on primates, which if successful would lead to trials on humans. 

‘A real breakthrough’?

The printer can make 100 patches in 48 hours. But modelling suggested that — with improvements — it could potentially print thousands a day, the researchers said.

“And you can have more than one printer,” Langer added.

Joseph DeSimone, a chemist at Stanford University not involved in the research, said that “this work is particularly exciting as it realizes the ability to produce vaccines on demand.” 

“With the possibility of scaling up vaccine manufacturing and improved stability at higher temperatures, mobile vaccine printers can facilitate widespread access to RNA vaccines,” said DeSimone, who has invented his own microneedle patches.

Antoine Flahault, director of the Institute of Global Health at the University of Geneva, said that production and access to vaccines could be “transformed through such a printer.”

“It might become a real breakthrough,” he told AFP, while warning that this depended on approval and mass production, which could take years.

Darrick Carter, a biochemist and CEO of U.S. biotech firm PAI Life Sciences, was less optimistic. 

He said that the field of microneedle patches had “suffered for 30 years” because no one had yet been able to scale up manufacturing in a cost-effective way.

“Until someone figures out the manufacturing scale-up issues for microneedle patches they will remain niche products,” he told AFP.

Twitter accounts operated by authoritarian governments in Russia, China and Iran are benefiting from recent changes at the social media company, researchers said Monday, making it easier for them to attract new followers and broadcast propaganda and disinformation to a larger audience. 

The platform is no longer labeling state-controlled media and propaganda agencies, and will no longer prohibit their content from being automatically promoted or recommended to users. Together, the two changes, both made in recent weeks, have supercharged the Kremlin’s ability to use the U.S.-based platform to spread lies and misleading claims about its invasion of Ukraine, U.S. politics and other topics. 

Russian state media accounts are now earning 33% more views than they were just weeks ago, before the change was made, according to findings released Monday by Reset, a London-based non-profit that tracks authoritarian governments’ use of social media to spread propaganda. Reset’s findings were first reported by The Associated Press. 

The increase works out to more than 125,000 additional views per post. Those posts included ones suggesting the CIA had something to do with the September 11, 2001, attacks on the U.S., that Ukraine’s leaders are embezzling foreign aid to their country, and that Russia’s invasion of Ukraine was justified because the U.S. was running clandestine biowarfare labs in the country. 

State media agencies operated by Iran and China have seen similar increases in engagement since Twitter quietly made the changes. 

The about-face from the platform is the latest development since billionaire Elon Musk purchased Twitter last year. Since then, he’s ushered in a confusing new verification system and laid off much of the company’s staff, including those dedicated to fighting misinformation, allowed back neo-Nazis and others formerly suspended from the site, and ended the site’s policy prohibiting dangerous COVID-19 misinformation. Hate speech and disinformation have thrived. 

Before the most recent change, Twitter affixed labels reading “Russia state-affiliated media” to let users know the origin of the content. It also throttled back the Kremlin’s online engagement by making the accounts ineligible for automatic promotion or recommendation—something it regularly does for ordinary accounts as a way to help them reach bigger audiences. 

The labels quietly disappeared after National Public Radio and other outlets protested Musk’s plans to label their outlets as state-affiliated media, too. NPR then announced it would no longer use Twitter, saying the label was misleading, given NPR’s editorial independence, and would damage its credibility. 

Reset’s conclusions were confirmed by the Atlantic Council’s Digital Forensic Research Lab (DFRL), where researchers determined the changes were likely made by Twitter late last month. Many of the dozens of previously labeled accounts were steadily losing followers since Twitter began using the labels. But after the change, many accounts saw big jumps in followers. 

RT Arabic, one of Russia’s most popular propaganda accounts on Twitter, had fallen to less than 5,230,000 followers on January 1, but rebounded after the change was implemented, the DFRL found. It now has more than 5,240,000 followers. 

Before the change, users interested in seeking out Kremlin propaganda had to search specifically for the account or its content. Now, it can be recommended or promoted like any other content. 

“Twitter users no longer must actively seek out state-sponsored content in order to see it on the platform; it can just be served to them,” the DFRL concluded. 

Twitter did not respond to questions about the change or the reasons behind it. Musk has made past comments suggesting he sees little difference between state-funded propaganda agencies operated by authoritarian strongmen and independent news outlets in the west.

“All news sources are partially propaganda,” he tweeted last year, “some more than others.”

Nine European countries held a summit on Monday aimed at scaling up wind power generation in the North Sea, spurred by the fallout from the war in Ukraine and the push for renewables. 

“We’ve seen over the past months what the impact is if you are too dependent on outsiders for the supply of energy,” said Belgian Prime Minister Alexander De Croo, who hosted the meeting in the coastal town of Ostend. 

The leaders of EU members France, Germany, Ireland, Denmark, the Netherlands and Luxembourg, along with European Commission chief Ursula von der Leyen, attended the summit. 

Norway and Britain also participated, with the latter represented by UK Energy Security Secretary Grant Shapps. 

In a joint op-ed published in Politico, the leaders of the nine nations emphasized the need to build more offshore wind turbines “to reach our climate goals, and to rid ourselves of Russian gas, ensuring a more secure and independent Europe.” 

Several leaders pointed to the need also to ensure security of offshore wind farms and their interconnectors, in the wake of recent reports of a Russian spy ship in the North Sea and last year’s sabotage of the Nord Stream gas pipelines in the Baltic Sea. 

De Croo said North Sea infrastructure, including turbines and undersea cables “are prone to sabotage or to espionage” and the topic was “an extremely important one” at the summit.

The summit’s collective goal, stated by all the leaders, is to boost offshore wind power generation to 120 gigawatts by 2030 — from just 30 GW today — and at least 300 GW by 2050.

They recognized the size of the task requires massive investment and that standardizing equipment is needed to bring down costs and timescales.

A key point, hammered by French President Emmanuel Macron, is to ensure the supply chain for the push for more North Sea wind power is anchored in Europe, rather than elsewhere, and that the jobs created are there.

“We want to secure our industrial chain, because it’s important to deploy this offshore wind power but we don’t want to repeat the errors we’ve sometimes committed in the past, of deploying equipment made on the other side of the world,” he said.

The comment appeared to be directed at China, which currently dominates the supply of critical elements, such as rare earth metals. The European Union is seeking to shift away from that reliance on China by bolstering its own industries.

German Chancellor Olaf Scholz said the “very important” summit underscored the potential to greatly expand renewable energy from the North Sea. 

Industry criticism 

WindEurope, an organization that promotes wind energy across Europe, believes the summit’s ambitions are achievable. But it highlighted a lack of “adequate funding mechanisms” and recruitment in the sector.

The organization says Europe needs to build the offshore infrastructure to add 20 GW in output per year, yet the sector currently has capacity for just seven GW annually, with supply chain bottlenecks for cables, substations and foundations, and in the availability of offshore support vessels.

Investment to get Europe where it wants to be is huge: The EU has calculated the cost of reaching 300 GW in offshore energy production by 2050 at $900 billion.

Britain has the biggest fleet of offshore wind farms, 45 of them, currently producing 14 GW, with plans to expand capacity to 50 GW by 2030.

Germany’s 30 wind farms produce 8 GW, followed by the Netherlands with 2.8 GW and Denmark and Belgium both with 2.3 GW.

The other participating countries produce less than a gigawatt from their existing installations but share ambitions to greatly ramp up wind energy capacity.

The AI bot ChatGPT has passed exams, written poetry, and deployed in newsrooms, and now politicians are seeking it out — but experts are warning against rapid uptake of a tool also famous for fabricating “facts.”

The chatbot, released last November by U.S. firm OpenAI, has quickly moved center stage in politics — particularly as a way of scoring points.

Japanese Prime Minister Fumio Kishida recently took a direct hit from the bot when he answered some innocuous questions about health care reform from an opposition MP.

Unbeknownst to the PM, his adversary had generated the questions with ChatGPT. He also generated answers that he claimed were “more sincere” than Kishida’s.

The PM hit back that his own answers had been “more specific.”

French trade union boss Sophie Binet was on-trend when she drily assessed a recent speech by President Emmanuel Macron as one that “could have been done by ChatGPT.”

But the bot has also been used to write speeches and even help draft laws. 

“It’s useful to think of ChatGPT and generative AI in general as a cliche generator,” David Karpf of George Washington University in the U.S. said during a recent online panel. 

“Most of what we do in politics is also cliche generation.”

‘Limited added value’

Nowhere has the enthusiasm for grandstanding with ChatGPT been keener than in the United States.

Last month, Congresswoman Nancy Mace gave a five-minute speech at a Senate committee enumerating potential uses and harms of AI — before delivering the punchline that “every single word” had been generated by ChatGPT.

Local U.S. politician Barry Finegold had already gone further though, pronouncing in January that his team had used ChatGPT to draft a bill for the Massachusetts Senate.

The bot reportedly introduced original ideas to the bill, which is intended to rein in the power of chatbots and AI.

Anne Meuwese from Leiden University in the Netherlands wrote in a column for Dutch law journal RegelMaat last week that she had carried out a similar experiment with ChatGPT and also found that the bot introduced original ideas.

But while ChatGPT was to some extent capable of generating legal texts, she wrote that lawmakers should not fall over each other to use the tool.

“Not only is much still unclear about important issues such as environmental impact, bias and the ethics at OpenAI … the added value also seems limited for now,” she wrote.

Agitprop bots

The added value might be more obvious lower down the political food chain, though, where staffers on the campaign trail face a treadmill of repetitive tasks.

Karpf suggested AI could be useful for generating emails asking for donations — necessary messages that were not intended to be masterpieces.

This raises an issue of whether the bots can be trained to represent a political point of view.

ChatGPT has already provoked a storm of controversy over its apparent liberal bias — the bot initially refused to write a poem praising Donald Trump but happily churned out couplets for his successor as U.S. President Joe Biden.

Billionaire magnate Elon Musk has spied an opportunity. Despite warning that AI systems could destroy civilization, he recently promised to develop TruthGPT, an AI text tool stripped of the perceived liberal bias.

Perhaps he needn’t have bothered. New Zealand researcher David Rozado already ran an experiment retooling ChatGPT as RightWingGPT — a bot on board with family values, liberal economics and other right-wing rallying cries.

“Critically, the computational cost of trialling, training and testing the system was less than $300,” he wrote on his Substack blog in February.

Not to be outdone, the left has its own “Marxist AI.”

The bot was created by the founder of Belgian satirical website Nordpresse, who goes by the pseudonym Vincent Flibustier.

He told AFP his bot just sends queries to ChatGPT with the command to answer as if it were an “angry trade unionist.”

The malleability of chatbots is central to their appeal but it goes hand-in-hand with the tendency to generate untruths, making AI text generators potentially hazardous allies for the political class.

“You don’t want to become famous as the political consultant or the political campaign that blew it because you decided that you could have a generative AI do [something] for you,” said Karpf.

April 24 – April 30, is World Immunization Week.

The theme of this year’s observance is “The Big Catch-Up.”

The idea is for everyone, especially children, to catch up on the vaccinations they might have missed during the COVID outbreak.

The ultimate goal of World Immunization Week, according the World Health Organization, is for more children, adults and their communities to be protected from vaccine-preventable diseases, like polio and measles.

Air pollution still causes more than 1,200 premature deaths a year in under 18’s across Europe and increases the risk of chronic disease later in life, the EU environmental agency said Monday.   

Despite recent improvements, “the level of key air pollutants in many European countries remain stubbornly above World Health Organization” (WHO) guidelines, particularly in central-eastern Europe and Italy, said the EEA after a study in over 30 countries, including the 27 members of the European Union.   

The report did not cover the major industrial nations of Russia, Ukraine and the United Kingdom, suggesting the overall death tolls for the continent could be higher.   

The EEA announced last November that 238,000 people died prematurely because of air pollution in 2020 in the EU, plus Iceland, Liechtenstein, Norway, Switzerland and Turkey.   

“Air pollution causes over 1,200 premature deaths per year in people under the age of 18 in Europe and significantly increases the risk of disease later in life,” the agency said.   

The study was the agency’s first to focus specifically on children.   

“Although the number of premature deaths in this age group is low relative to the total for the European population estimated by EEA each year, deaths early in life represent a loss of future potential and come with a significant burden of chronic illness, both in childhood and later in life,” the agency said.  

It urged authorities to focus on improving air quality around schools and nurseries as well as sports facilities and mass transport hubs.   

“After birth, ambient air pollution increases the risk of several health problems, including asthma, reduced lung function, respiratory infections and allergies,” the report noted.   

7 million dead annually 

Poor air quality can also “aggravate chronic conditions like asthma, which afflicts nine percent of children and adolescents in Europe, as well as increasing the risk of some chronic diseases later in adulthood.”   

Ninety-seven percent of the urban population were in 2021 exposed to air that did not meet WHO recommendations, according to figures released Monday.   

The EEA had last year underlined that the EU was on track to meet its target of reducing premature deaths by 50% by 2030 compared with 2005.   

In the early 1990s, fine particulates caused nearly a million premature deaths a year in the 27 EU nations. That fell to 431,000 in 2005.   

The situation in Europe looks better than for much of the planet, says the WHO, which blames air pollution for 7 million deaths globally each year, almost as many as for cigarette smoking or bad diets.   

It took until September 2021 to reach agreement to tighten limits set for major pollutants back in 2005.   

In Thailand alone, where toxic smog chokes parts of the country, health officials said last week that 2.4 million people had sought hospital treatment for medical problems linked to air pollution since the start of the year.   

Fine particulate matter, primarily from cars and trucks and which can penetrate deeply into the lungs, is considered the worst air pollutant, followed by nitrogen dioxide and ozone.

At age 93, struggling with the effects of a stroke, heart failure and recurrent cancer, Teri Sheridan was ready to end her life using New Jersey’s law that allows medically assisted suicide — but she was bedbound, too sick to travel.

So last Nov. 17, surrounded by three of her children, Sheridan drank a lethal dose of drugs prescribed by a doctor she had never met in person, only online. She died within minutes.

Soon, others who seek Sheridan’s final option may find it out of reach, the unintended result of a federal move to roll back online prescribing of potentially addictive drugs allowed during the COVID-19 pandemic.

“How much should one person suffer?” said Sheridan’s daughter, Georgene White, 68. “She wanted to just go to sleep and not wake up.”

Online prescribing rules for controlled drugs were relaxed three years ago under emergency waivers to ensure critical medications remained available during the COVID-19 pandemic. Now, the U.S. Drug Enforcement Administration has proposed a rule that would reinstate most previously longstanding requirements that doctors see patients in person before prescribing narcotic drugs such as Oxycontin, amphetamines such as Adderall, and a host of other potentially dangerous drugs.

The aim is to reduce improper prescribing of these drugs by telehealth companies that boomed during the pandemic. Given the ongoing opioid epidemic, allowing continued broad use of telemedicine prescribing “would pose too great a risk to the public health and safety,” the proposed rule said. It also cracks down on how doctors can prescribe other less-addictive drugs, like Xanax, used to treat anxiety, and buprenorphine, a narcotic used to treat opioid addiction.

The rule would allow some of these drugs to be prescribed with telemedicine for an initial 30-day dose, though patients would need to be seen in person to get a refill. And patients who have been referred to a new doctor by one they had previously met in person could continue to receive prescriptions for the drugs via telemedicine.

DEA Administrator Anne Milgram called the plan “telemedicine with guardrails.”

The agency, with input from the Department of Health and Human Services, is working to finalize the rule by May 11, when the COVID public health emergency officially ends, an HHS spokeswoman said. If approved by then, the new requirements would take effect in November.

The proposal has sparked a massive backlash, including more than 35,000 comments to a federal portal and calls from advocates, members of Congress and medical groups to reconsider certain patients or provisions.

“They completely forgot that there was a population of people who are dying,” said Dr. Lonny Shavelson, a California physician who chairs the American Clinicians Academy on Medical Aid in Dying, a coalition of doctors who help patients access care under so-called right-to-die laws.

Among the biggest complaints: The rule would delay or block access for patients who seek medically assisted suicide and hospice care, critics said. Many of the comments — including nearly 10,000 delivered in person to DEA offices — came from doctors and patients protesting the effect of the rule on seriously ill and dying patients.

“Please do not make the end of life harder for me,” wrote Lynda Bluestein, 75, of Bridgeport, Connecticut. In March, Bluestein, who has terminal fallopian tube cancer, reached a settlement with the state of Vermont that will allow her to be the first non-resident to use its medically assisted suicide law. By the time she’s ready to use the drugs, she expects to be too ill to travel to see a doctor in person for the prescription, she wrote.

The clash between desperate patients who need treatment and DEA’s efforts to bar telehealth companies from overprescribing dangerous medications was inevitable, said David Herzberg, a historian of drugs at the University of Buffalo.

“The balancing act is so tricky,” he said.

Laws in 10 states and Washington allow dying people with a prognosis of six months or less to end their lives with a lethal combination of medications covered by the DEA rule. But such patients are often too sick to visit a doctor in person or they live hundreds of kilometers from the nearest willing and qualified provider, Shavelson said.

There are similar issues for the 1.7 million Medicare recipients enrolled in hospice care in the United States, said Judi Lund Person, who oversees regulatory compliance for the National Hospice and Palliative Care Organization. Rolling back online prescribing flexibilities could mean a dying patient would wait for days for drugs to ease pain and other symptoms.

“They just don’t have time for that,” she said.

Shavelson and his colleagues called for an exception to the rule for the hundreds of patients a year who qualify for medically assisted suicide. Both the American Medical Association and the California Medical Association sent letters asking the DEA to carve out provisions for doctors prescribing the most dangerous category of drugs to patients receiving hospice or palliative care.

“These patients are extremely fragile and their medical conditions do not allow them to easily access a physician’s office,” wrote Dr. Donaldo D. Hernandez, president of the California group. Such people pose a “reduced risk for abuse” given their clear need for the medications.

Congress directed the DEA in 2008 to create exceptions for certain providers to permit remote prescribing, but the agency has not done so, Virginia Democrat Sen. Mark Warner said in a statement last month.

DEA officials did not respond to questions about whether COVID-19 telehealth waivers would remain in effect if the proposed rule isn’t finalized by May 11 or whether the agency will allow exceptions for remote prescribing.

During the pandemic, prescriptions for medically assisted suicide went up, in some cases significantly. In Oregon, for instance, they climbed nearly 49%, to 432 in 2022 from 290 in 2019. The number of deaths under the law in that state rose, too, to 246 from 170. Nationally, at least 1,300 people die each year using the process, according to available state figures.

Telemedicine was key to access during the COVID emergency, said Dr. Robin Plumer, the New Jersey doctor who prescribed the drugs Teri Sheridan took. Plumer has overseen 80 assisted suicide deaths since 2020. Without online prescribing, 35% to 40% of her patients wouldn’t have been able to use the law.

“I feel like we’ve taught people over the past couple of years that telemedicine does work in so many areas and it’s a great improvement for people,” especially for those who are homebound or dying, Plumer said.

“And what?” she said. “They’re suddenly going to yank that away?”

The Biden administration announced more than $80 million in funding Thursday in a push to produce more solar panels in the U.S., make solar energy available to more people, and pursue superior alternatives to the ubiquitous sparkly panels made with silicon.

The initiative, spearheaded by the U.S. Department of Energy (DOE) and known as Community solar, encompasses a variety of arrangements where renters and people who don’t control their rooftops can still get their electricity from solar power. Two weeks ago, Vice President Kamala Harris announced what the administration said was the largest community solar effort ever in the United States.

Now it is set to spend $52 million on 19 solar projects across a dozen states, including $10 million from the infrastructure law, as well as $30 million on technologies that will help integrate solar electricity into the grid.

The DOE also selected 25 teams to participate in a $10 million competition designed to fast-track the efforts of solar developers working on community solar projects.

The Inflation Reduction Act already offers incentives to build large solar generation projects, such as renewable energy tax credits. But Ali Zaidi, White House national climate adviser, said the new money focuses on meeting the nation’s climate goals in a way that benefits more communities.

“It’s lifting up our workers and our communities. And that’s, I think, what really excites us about this work,” Zaidi said. “It’s a chance not just to tackle the climate crisis, but to bring economic opportunity to every zip code of America.”

The investments will help people save on their electricity bills and make the electricity grid more reliable, secure, and resilient in the face of a changing climate, said Becca Jones-Albertus, director of the energy department’s Solar Energy Technologies Office.

Jones-Albertus said she’s particularly excited about the support for community solar projects, since half of Americans don’t live in a situation where they can buy their own solar and put in on the roof.

Michael Jung, executive director of the ICF Climate Center agreed. “Community solar can help address equity concerns, as most current rooftop solar panels benefit owners of single-family homes,” he said.

In typical community solar projects, households can invest in or subscribe to part of a larger solar array offsite. “What we’re doing here is trying to unlock the community solar market,” Jones-Albertus said.

The U.S. has 5.3 gigawatts of installed community solar capacity currently, according to the latest estimates. The goal is that by 2025, five million households will have access to it — about three times as many as today — saving $1 billion on their electricity bills, according to Jones-Albertus.

The new funding also highlights investment in a next generation of solar technologies, intended to wring more electricity out of the same amount of solar panels. Currently only about 20% of the sun’s energy is converted to electricity in crystalline silicon solar cells, which is what most solar panels are made of. There has long been hope for higher efficiency, and today’s announcement puts some money towards developing two alternatives: perovskite and cadmium telluride (CdTe) solar cells. Zaidi said this will allow the U.S. to be “the innovation engine that tackles the climate crisis.”

Joshua Rhodes, a scientist at the University of Texas at Austin said the investment in perovskites is good news. They can be produced more cheaply than silicon and are far more tolerant of defects, he said. They can also be built into textured and curved surfaces, which opens up more applications for their use than traditional rigid panels. Most silicon is produced in China and Russia, Rhodes pointed out.

Cadmium telluride solar can be made quickly and at a low cost, but further research is needed to improve how efficient the material is at converting sunlight to electrons.

Cadmium is also toxic and people shouldn’t be exposed to it. Jones-Albertus said that in cadmium telluride solar technology, the compound is encapsulated in glass and additional protective layers.

The new funds will also help recycle solar panels and reuse rare earth elements and materials. “One of the most important ways we can make sure CdTe remains in a safe compound form is ensuring that all solar panels made in the U.S. can be reused or recycled at the end of their life cycle,” Jones-Albertus explained.

Recycling solar panels also reduces the need for mining, which damages landscapes and uses a lot of energy, in part to operate the heavy machinery. Eight of the projects in Thursday’s announcement focus on improving solar panel recycling, for a total of about $10 million.

Clean energy is a fit for every state in the country, the administration said. One solar project in Shungnak, Alaska, was able to eliminate the need to keep making electricity by burning diesel fuel, a method sometimes used in remote communities that is not healthy for people and contributes to climate change.

“Alaska is not a place that folks often think of when they think about solar, but this energy can be an economic and affordable resource in all parts of the country,” said Jones-Albertus.

The U.S. Supreme Court on Friday preserved access to the abortion drug mifepristone while a lawsuit challenging the use of the drug plays out in lower courts.

The high court issued a brief on Friday evening granting emergency requests from the Biden administration and the drug’s manufacturer, Danco Laboratories, to continue to allow women to access the drug. The ruling puts on hold a preliminary injunction from a federal judge in Texas, who earlier this month ordered restrictions on the abortion drug.

Two justices on the nine-member court — conservatives Clarence Thomas and Samuel Alito — dissented from the decision.

The court had set a deadline for itself of midnight Friday to either approve the Biden administration’s request — to keep the drug available while the administration challenges a lower court ruling — or allow limited access to the drug to take effect.

The lower court ruling in question was issued April 7 by a federal judge in Texas after a coalition of anti-abortion groups and doctors argued the U.S. drug regulator, the Food and Drug Administration, improperly approved mifepristone in 2000 and did not fully assess its risks and benefits.

The ruling, which strictly limits availability of the drug, was appealed, and while an appeals court halted a portion of the ruling that would have invalidated the FDA approval, it left the limits on the drug’s availability in place.

The case is expected to be further appealed and could eventually end up being decided by the Supreme Court. Friday’s high court ruling makes it likely that access to mifepristone will continue at least into next year as the appeals play out.

Used in half of all abortions in US

Mifepristone is used in about half of all abortions nationwide. It has been used by as many as 5 million women since it was first approved in 2000, and major medical organizations say it has a strong safety record. The drug is also commonly used to help manage miscarriages.

Currently, the drug can be used by women to end pregnancies in the first 10 weeks, without a surgical procedure. It is available through the mail without an in-person visit to a doctor.

At the time the lower court ruling was made restricting access to the drug, President Joe Biden said in a statement the judge substituted his own judgment for that of the FDA, the expert agency responsible for approving drugs.

Biden said if the ruling is allowed to stand, “there will be virtually no prescription approved by the FDA that would be safe from these kinds of political, ideological attacks.”

Fight follows reversal of Roe v. Wade

The judge who made the ruling, U.S. District Judge Matthew Kacsmaryk, was appointed by former President Donald Trump, as were the judges on the appeals court that maintained limits on the availability of the drug.

The fight over mifepristone comes after the conservative majority on the Supreme Court last year overturned the landmark Roe v. Wade decision that legalized abortion nationwide. The court ruled it is now up to individual states to decide whether abortion should be legal or not.

The FDA has in recent years made it easier to use mifepristone, including in 2016 approving its use to 10 weeks of pregnancy, up from seven, and in 2021 allowing it to be distributed by mail in states that allow access.

Competition between the U.S. and China in artificial intelligence has expanded into a race to design and implement comprehensive AI regulations.

The efforts to come up with rules to ensure AI’s trustworthiness, safety and transparency come at a time when governments around the world are exploring the impact of the technology on national security and education.

ChatGPT, a chatbot that mimics human conversation, has received massive attention since its debut in November. Its ability to give sophisticated answers to complex questions with a language fluency comparable to that of humans has caught the world by surprise. Yet its many flaws, including its ostensibly coherent responses laden with misleading information and apparent bias, have prompted tech leaders in the U.S. to sound the alarm.

“What happens when something vastly smarter than the smartest person comes along in silicon form? It’s very difficult to predict what will happen in that circumstance,” said Tesla Chief Executive Officer Elon Musk in an interview with Fox News. He warned that artificial intelligence could lead to “civilization destruction” without regulations in place.

Google CEO Sundar Pichai echoed that sentiment. “Over time there has to be regulation. There have to be consequences for creating deep fake videos which cause harm to society,” Pichai said in an interview with CBS’s “60 Minutes” program.

Jessica Brandt, policy director for the Artificial Intelligence and Emerging Technology Initiative at the Brookings Institution, told VOA Mandarin, “Business leaders understand that regulators will be watching this space closely, and they have an interest in shaping the approaches regulators will take.”

US grapples with regulations

AI regulation is still nascent in the U.S. Last year, the White House released voluntary guidance through a Blueprint for an AI Bill of Rights to help ensure users’ rights are protected as technology companies design and develop AI systems.

At a meeting of the President’s Council of Advisors on Science and Technology this month, President Joe Biden expressed concern about the potential dangers associated with AI and underscored that companies had a responsibility to ensure their products were safe before making them public.

On April 11, the National Telecommunications and Information Administration, a Commerce Department agency that advises the White House on telecommunications and information policy, began to seek comment and public input with the aim of crafting a report on AI accountability.

The U.S. government is trying to find the right balance to regulate the industry without stifling innovation “in part because the U.S. having innovative leadership globally is a selling point for the United States’ hard and soft power,” said Johanna Costigan, a junior fellow at the Asia Society Policy Institute’s Center for China Analysis.

Brandt, with Brookings, said, “The challenge for liberal democracies is to ensure that AI is developed and deployed responsibly, while also supporting a vibrant innovation ecosystem that can attract talent and investment.”

Meanwhile, other Western countries have also started to work on regulating the emerging technology.

The U.K. government published its AI regulatory framework in March. Also last month, Italy temporarily blocked ChatGPT in the wake of a data breach, and the German commissioner for data protection said his country could follow suit.

The European Union stated it’s pushing for an AI strategy aimed at making Europe a world-class hub for AI that ensures AI is human-centric and trustworthy, and it hopes to lead the world in AI standards.

Cyber regulations in China

In contrast to the U.S., the Chinese government has already implemented regulations aimed at tech sectors related to AI. In the past few years, Beijing has introduced several major data protection laws to limit the power of tech companies and to protect consumers.

The Cybersecurity Law enacted in 2017 requires that data must be stored within China and operators must submit to government-conducted security checks. The Data Security Law enacted in 2021 sets a comprehensive legal framework for processing personal information when doing business in China. The Personal Information Protection Law established in the same year gives Chinese consumers the right to access, correct and delete their personal data gathered by businesses. Costigan, with the Asia Society, said these laws have laid the groundwork for future tech regulations.

In March 2022, China began to implement a regulation that governs the way technology companies can use recommendation algorithms. The Cyberspace Administration of China (CAC) now supervises the process of using big data to analyze user preferences and companies’ ability to push information to users.

On April 11, the CAC unveiled a draft for managing generative artificial intelligence services similar to ChatGPT, in an effort to mitigate the dangers of the new technology.

Costigan said the goal of the proposed generative AI regulation could be seen in Article 4 of the draft, which states that content generated by future AI products must reflect the country’s “core socialist values” and not encourage subversion of state power.

“Maintaining social stability is a key consideration,” she said. “The new draft regulation does some good and is unambiguously in line with [President] Xi Jinping’s desire to ensure that individuals, companies or organizations cannot use emerging AI applications to challenge his rule.”

Michael Caster, the Asia digital program manager at Article 19, a London-based rights organization, told VOA, “The language, especially at Article 4, is clearly about maintaining the state’s power of censorship and surveillance.

“All global policymakers should be clearly aware that while China may be attempting to set standards on emerging technology, their approach to legislation and regulation has always been to preserve the power of the party.”

The future of cyber regulations

As strategies for cyber and AI regulations evolve, how they develop may largely depend on each country’s way of governance and reasons for creating standards. Analysts say there will also be intrinsic hurdles linked to coming up with consensus.

“Ethical principles can be hard to implement consistently, since context matters and there are countless potential scenarios at play,” Brandt told VOA. “They can be hard to enforce, too. Who would take on that role? How? And of course, before you can implement or enforce a set of principles, you need broad agreement on what they are.”

Observers said the international community would face challenges as it creates standards aimed at making AI technology ethical and safe.

U.S. homeland security officials are launching what they describe as two urgent initiatives to combat growing threats from China and expanding dangers from ever more capable, and potentially malicious, artificial intelligence.

Homeland Security Secretary Alejandro Mayorkas announced Friday that his department was starting a “90-day sprint” to confront more frequent and intense efforts by China to hurt the United States, while separately establishing an artificial intelligence task force.

“Beijing has the capability and the intent to undermine our interests at home and abroad and is leveraging every instrument of its national power to do so,” Mayorkas warned, addressing the threat from China during a speech at the Council on Foreign Relations in Washington.

The 90-day sprint will “assess how the threats posed by the PRC [People’s Republic of China] will evolve and how we can be best positioned to guard against future manifestations of this threat,” he said.

“One critical area we will assess, for example, involves the defense of our critical infrastructure against PRC or PRC-sponsored attacks designed to disrupt or degrade provision of national critical functions, sow discord and panic, and prevent mobilization of U.S. military capabilities,” Mayorkas added.

Other areas of focus for the sprint will include addressing ways to stop Chinese government exploitation of U.S. immigration and travel systems to spy on the U.S. government and private entities and to silence critics, and looking at ways to disrupt the global fentanyl supply chain.

AI dangers

Mayorkas also said the magnitude of the threat from artificial intelligence, appearing in a growing number of tools from major tech companies, was no less critical.

“We must address the many ways in which artificial intelligence will drastically alter the threat landscape and augment the arsenal of tools we possess to succeed in the face of these threats,” he said.

Mayorkas promised that the Department of Homeland Security “will lead in the responsible use of AI to secure the homeland and in defending against the malicious use of this transformational technology.”

The new task force is set to seek ways to use AI to protect U.S. supply chains and critical infrastructure, counter the flow of fentanyl, and help find and rescue victims of online child sexual exploitation.

The unveiling of the two initiatives came days after lawmakers grilled Mayorkas about what some described as a lackluster and derelict effort under his leadership to secure the U.S. border with Mexico.

“You have not secured our borders, Mr. Secretary, and I believe you’ve done so intentionally,” the chair of the House Homeland Security Committee, Republican Mark Green, told Mayorkas on Wednesday.

Another lawmaker, Republican Marjorie Taylor Greene, went as far as to accuse Mayorkas of lying, though her words were quickly removed from the record.

Mayorkas on Friday said it might be possible to use AI to help with border security, though how exactly it could be deployed for the task was not yet clear.

“We’re at a nascent stage of really deploying AI,” he said. “I think we’re now at the dawn of a new age.”

But Mayorkas cautioned that technologies like AI would do little to slow the number of migrants willing to embark on dangerous journeys to reach U.S. soil.

“Desperation is the greatest catalyst for the migration we are seeing,” he said.

FBI warning

The announcement of Homeland Security’s 90-day sprint to confront growing threats from Beijing followed a warning earlier this week from the FBI about the willingness of China to target dissidents and critics in the U.S.

and the arrests of two New York City residents for their involvement in a secret Chinese police station.

China has denied any wrongdoing.

“The Chinese government strictly abides by international law, and fully respects the law enforcement sovereignty of other countries,” Liu Pengyu, the spokesman for the Chinese Embassy in Washington, told VOA in an email earlier this week, accusing the U.S. of seeking “to smear China’s image.”

Top U.S. officials have said they are opening two investigations daily into Chinese economic espionage in the U.S.

“The Chinese government has stolen more of American’s personal and corporate data than that of every nation, big or small combined,” FBI Director Christopher Wray told an audience late last year.

More recently, Wray warned of Chinese’ advances in AI, saying he was “deeply concerned.”

Mayorkas voiced a similar sentiment, pointing to China’s use of investments and technology to establish footholds around the world.

“We are deeply concerned about PRC-owned and -operated infrastructure, elements of infrastructure, and what that control can mean, given that the operator and owner has adverse interests,” Mayorkas said Friday.

“Whether it’s investment in our ports, whether it is investment in partner nations, telecommunications channels and the like, it’s a myriad of threats,” he said.
