Washington — Two Air Force fighter jets recently squared off in a dogfight in California. One was flown by a pilot. The other wasn’t.

That second jet was piloted by artificial intelligence, with the Air Force’s highest-ranking civilian riding along in the front seat. It was the ultimate display of how far the Air Force has come in developing a technology with its roots in the 1950s. But it’s only a hint of the technology yet to come.

The United States is competing to stay ahead of China on AI and its use in weapon systems. The focus on AI has generated public concern that future wars will be fought by machines that select and strike targets without direct human intervention. Officials say this will never happen, at least not on the U.S. side. But there are questions about what a potential adversary would allow, and the military sees no alternative but to get U.S. capabilities fielded fast.

“Whether you want to call it a race or not, it certainly is,” said Adm. Christopher Grady, vice chairman of the Joint Chiefs of Staff. “Both of us have recognized that this will be a very critical element of the future battlefield. China’s working on it as hard as we are.”

A look at the history of military development of AI, what technologies are on the horizon and how they will be kept under control:

From machine learning to autonomy

AI’s military roots are a hybrid of machine learning and autonomy. Machine learning occurs when a computer analyzes data and rule sets to reach conclusions. Autonomy occurs when those conclusions are applied to act without further human input.

This took an early form in the 1960s and 1970s with the development of the Navy’s Aegis missile defense system. Aegis was trained through a series of human-programmed if/then rule sets to be able to detect and intercept incoming missiles autonomously, and more rapidly than a human could. But the Aegis system was not designed to learn from its decisions and its reactions were limited to the rule set it had.

“If a system uses ‘if/then’ it is probably not machine learning, which is a field of AI that involves creating systems that learn from data,” said Air Force Lt. Col. Christopher Berardi, who is assigned to the Massachusetts Institute of Technology to assist with the Air Force’s AI development.

AI took a major step forward in 2012 when the combination of big data and advanced computing power enabled computers to begin analyzing the information and writing the rule sets themselves. It is what AI experts have called AI’s “big bang.”

The new data created by a computer writing the rules is artificial intelligence. Systems can be programmed to act autonomously from the conclusions reached from machine-written rules, which is a form of AI-enabled autonomy.

Testing an AI alternative to GPS navigation

Air Force Secretary Frank Kendall got a taste of that advanced warfighting this month when he flew on Vista, the first F-16 fighter jet to be controlled by AI, in a dogfighting exercise over California’s Edwards Air Force Base.

While that jet is the most visible sign of the AI work underway, there are hundreds of ongoing AI projects across the Pentagon.

At MIT, service members worked to clear thousands of hours of recorded pilot conversations to create a data set from the flood of messages exchanged between crews and air operations centers during flights, so the AI could learn the difference between critical messages like a runway being closed and mundane cockpit chatter. The goal was to have the AI learn which messages are critical to elevate to ensure controllers see them faster.

In another significant project, the military is working on an AI alternative to GPS satellite-dependent navigation.

In a future war high-value GPS satellites would likely be hit or interfered with. The loss of GPS could blind U.S. communication, navigation and banking systems and make the U.S. military’s fleet of aircraft and warships less able to coordinate a response.

So last year the Air Force flew an AI program — loaded onto a laptop that was strapped to the floor of a C-17 military cargo plane — to work on an alternative solution using the Earth’s magnetic fields.

It has been known that aircraft could navigate by following the Earth’s magnetic fields, but so far that hasn’t been practical because each aircraft generates so much of its own electromagnetic noise that there has been no good way to filter for just the Earth’s emissions.

“Magnetometers are very sensitive,” said Col. Garry Floyd, director for the Department of Air Force-MIT Artificial Intelligence Accelerator program. “If you turn on the strobe lights on a C-17 we would see it.”

The AI learned through the flights and reams of data which signals to ignore and which to follow and the results “were very, very impressive,” Floyd said. “We’re talking tactical airdrop quality.”

“We think we may have added an arrow to the quiver in the things we can do, should we end up operating in a GPS-denied environment. Which we will,” Floyd said.

The AI so far has been tested only on the C-17. Other aircraft will also be tested, and if it works it could give the military another way to operate if GPS goes down.

Safety rails and pilot speak

Vista, the AI-controlled F-16, has considerable safety rails as the Air Force trains it. There are mechanical limits that keep the still-learning AI from executing maneuvers that would put the plane in danger. There is a safety pilot, too, who can take over control from the AI with the push of a button.

The algorithm cannot learn during a flight, so each time up it has only the data and rule sets it has created from previous flights. When a new flight is over, the algorithm is transferred back onto a simulator where it is fed new data gathered in-flight to learn from, create new rule sets and improve its performance.

But the AI is learning fast. Because of the supercomputing speed AI uses to analyze data, and then flying those new rule sets in the simulator, its pace in finding the most efficient way to fly and maneuver has already led it to beat some human pilots in dogfighting exercises.

But safety is still a critical concern, and officials said the most important way to take safety into account is to control what data is reinserted into the simulator for the AI to learn from.

Washington — The first living patient to receive a genetically modified pig kidney transplant has died two months after the procedure, the US hospital that carried it out said.

“Mass General is deeply saddened at the sudden passing of Mr. Rick Slayman. We have no indication that it was the result of his recent transplant,” the Boston hospital said in a statement issued late Saturday.

In a world first, surgeons at Massachusetts General Hospital in March successfully transplanted the genetically edited pig kidney into Slayman, who was 62 years old at the time and suffering from end-stage kidney disease.

“Slayman will forever be seen as a beacon of hope to countless transplant patients worldwide and we are deeply grateful for his trust and willingness to advance the field of xenotransplantation,” the hospital statement said.

Organ shortages are a chronic problem around the world and Mass General said in March that there were more than 1,400 patients on its waiting list for a kidney transplant.

The pig kidney used for the transplant was provided by a Massachusetts biotech company called eGenesis and had been modified to remove harmful pig genes and add certain human genes, according to the hospital.

Slayman, who suffered from Type 2 diabetes and hypertension, had received a transplanted human kidney in 2018, but it began to fail five years later.

When the hospital announced the successful transplant in March, Slayman said he had agreed to the procedure “not only as a way to help (him), but a way to provide hope for the thousands of people who need a transplant to survive.”

In a statement posted on Mass General’s website, his family said while they were “deeply saddened about the sudden passing of our beloved Rick” they took “great comfort knowing he inspired so many.”

The family said they were “comforted by the optimism he provided patients desperately waiting for a transplant”.

More than 89,000 patients were on the national kidney waiting list as of March this year, according to a US health department website.

On average, 17 people die each day while waiting for an organ transplant.

Slayman’s family also thanked the doctors “who truly did everything they could to help give Rick a second chance. Their enormous efforts leading the xenotransplant gave our family seven more weeks with Rick, and our memories made during that time will remain in our minds and hearts.”

“After his transplant, Rick said that one of the reasons he underwent this procedure was to provide hope for the thousands of people who need a transplant to survive,” the family added.

“His legacy will be one that inspires patients, researchers, and health care professionals.”

The transplantation of organs from one species to another is a growing field known as xenotransplantation.

About a month after Slayman’s procedure, surgeons at NYU Langone Health in New York carried out a similar transplant on Lisa Pisano, who had suffered heart failure and end-stage kidney disease.

Pig kidneys had been transplanted previously into brain-dead patients, but Slayman was the first living person to receive one.

Genetically modified pig hearts were transplanted in 2023 into two patients at the University of Maryland, but both lived less than two months.

Mass General said Slayman’s transplant had been carried out under a policy known as “compassionate use” that allows patients with “serious or life-threatening conditions” to access experimental therapies not yet approved by the US Food and Drug Administration.

New York — All dogs coming into the U.S. from other countries must be at least 6 months old and microchipped to help prevent the spread of rabies, according to new government rules published Wednesday.

The new rules require vaccination for dogs that have been in countries where rabies is common. The update applies to dogs brought in by breeders or rescue groups as well as pets traveling with their U.S. owners.

“This new regulation is going to address the current challenges that we’re facing,” said Emily Pieracci, a rabies expert at the Centers for Disease Control and Prevention who was involved in drafting the updated regulations.

The CDC posted the new rules in the federal register on Wednesday. They take effect Aug. 1 when a temporary 2021 order expires. That order suspended bringing in dogs from more than 100 countries where rabies is still a problem.

The new rules require all dogs entering the U.S. to be at least 6 months, old enough to be vaccinated if required, and for the shots to take effect; have a microchip placed under their skin with a code that can be used to verify rabies vaccination; and have completed a new CDC import form.

There may be additional restrictions and requirements based on where the dog was the previous six months, which may include blood testing from CDC-approved labs.

The CDC regulations were last updated in 1956, and a lot has changed, Pieracci said. More people travel internationally with their pets, and more rescue groups and breeders have set up overseas operations to meet the demand for pets, she said. Now, about 1 million dogs enter the U.S. each year.

Dogs were once common carriers of the rabies virus in the U.S. but the type that normally circulates in dogs was eliminated through vaccinations in the 1970s. The virus invades the central nervous system and is usually a fatal disease in animals and humans. It’s most commonly spread through a bite from an infected animal. There is no cure for it once symptoms begin.

Four rabid dogs have been identified entering the U.S. since 2015, and officials worried more might get through. CDC officials also were seeing an increase of incomplete or fraudulent rabies vaccination certificates and more puppies denied entry because they weren’t old enough to be fully vaccinated.

A draft version of the updated regulations last year drew a range of public comments.

Angela Passman, owner of a Dallas company that helps people move their pets internationally, supports the new rules. It can especially tricky for families that buy or adopt a dog while overseas and then try to bring it to the U.S., she said. The update means little change from how things have been handled in recent years, she said.

“It’s more work for the pet owner, but the end result is a good thing,” said Passman, who is a board member for the International Pet and Animal Transportation Association.

But Jennifer Skiff said some of the changes are unwarranted and too costly. She works for Animal Wellness Action, a Washington group focused on preventing animal cruelty that helps organizations import animals.

She said those groups work with diplomats and military personnel who have had trouble meeting requirements, and was a reason some owners were forced to leave their dogs behind.

sacramento, california — California could soon deploy generative artificial intelligence tools to help reduce traffic jams, make roads safer and provide tax guidance, among other things, under new agreements announced Thursday as part of Governor Gavin Newsom’s efforts to harness the power of new technologies for public services. 

The state is partnering with five companies to create generative AI tools using technologies developed by tech giants such as Microsoft-backed OpenAI and Google- and Amazon-backed Anthropic that would ultimately help the state provide better services to the public, administration officials said. 

“It is a very good sign that a lot of these companies are putting their focus on using GenAI for governmental service delivery,” said Amy Tong, secretary of government operations for California. 

The companies will start a six-month internal trial in which state workers test and evaluate the tools. The companies will be paid $1 for their proposals. The state, which faces a significant budget deficit, can then reassess whether any tools could be fully implemented under new contracts. All the tools are considered low risk, meaning they don’t interact with confidential data or personal information, an administration spokesperson said. 

Newsom, a Democrat, touts California as a global hub for AI technology, noting 35 of the world’s top 50 AI companies are located in the state. He signed an executive order last year requiring the state to start exploring responsible ways to incorporate generative AI by this summer, with a goal of positioning California as an AI leader.

In January, the state started asking technology companies to come up with generative AI tools for public services. Last month, California was one of the first states to roll out guidelines on when and how state agencies could buy such tools. 

Generative AI, a branch of AI that can create new content such as text, audio and photos, has significant potential to help government agencies become more efficient, but there’s also an urgent need for safeguards to limit risks, state officials and experts said. In New York City, an AI-powered chatbot created by the city to help small businesses was found to dole out false guidance and advise companies to violate the law. The rapidly growing technology has also raised concerns about job losses, misinformation, privacy and automation bias. 

While state governments are struggling to regulate AI in the private sector, many are exploring how public agencies can leverage the powerful technology for public good. California’s approach, which also requires companies to disclose what large language models they use to develop AI tools, is meant to build public trust, officials said. 

The state’s testing of the tools and collecting of feedback from state workers are some of the best practices to limit potential risks, said Meredith Lee, chief technical adviser for the University of California-Berkeley’s College of Computing, Data Science and Society. The challenge is determining how to assure continued testing and learning about the tools’ potential risks after deployment. 

“This is not something where you just work on testing for some small amount of time and that’s it,” Lee said. “Putting in the structures for people to be able to revisit and better understand the deployments further down the line is really crucial.” 

The California Department of Transportation is looking for tools that would analyze traffic data and come up with solutions to reduce highway traffic and make roads safer. The state’s Department of Tax and Fee Administration, which administers more than 40 programs, wants an AI tool to help its call center cut wait times and call length. The state is also seeking technologies to provide non-English speakers information about health and social services benefits in their languages and to streamline the inspection process for health care facilities. 

The tools are to be designed to assist state workers, not replace them, said Nick Maduros, director of the Department of Tax and Fee Administration. 

Call center workers there took more than 660,000 calls last year. The state envisions the AI technology listening along to those calls and pulling up specific tax code information associated with the problems callers describe. Workers  could decide whether to use the information.

Currently, call center workers have to simultaneously listen to the call and manually look up the code, Maduros said. 

“If it turns out it doesn’t serve the public better, then we’re out $1,” Maduros said. “And I think that’s a pretty good deal for the citizens of California.” 

Tong wouldn’t say when a successfully vetted tool would be deployed, but added that the state was moving as fast as it can. 

“The whole essence of using GenAI is it doesn’t take years,” Tong said. “GenAI doesn’t wait for you.”

NEW YORK — A newly released ad promoting Apple’s new iPad Pro has struck quite a nerve online.

The ad, which was released by the tech giant Tuesday, shows a hydraulic press crushing just about every creative instrument artists and consumers have used over the years — from a piano and record player, to piles of paint, books, cameras and relics of arcade games. Resulting from the destruction? A pristine new iPad Pro.

“The most powerful iPad ever is also the thinnest,” a narrator says at the end of the commercial.

Apple’s intention seems straightforward: Look at all the things this new product can do. But critics have called it tone-deaf — with several marketing experts noting the campaign’s execution didn’t land.

“I had a really disturbing reaction to the ad,” said Americus Reed II, professor of marketing at The Wharton School of the University of Pennsylvania. “I understood conceptually what they were trying to do, but … I think the way it came across is, here is technology crushing the life of that nostalgic sort of joy (from former times).”

The ad also arrives during a time many feel uncertain or fearful about seeing their work or everyday routines “replaced” by technological advances — particularly amid the rapid commercialization of generative artificial intelligence. And watching beloved items get smashed into oblivion doesn’t help curb those fears, Reed and others note.

Several celebrities were also among the voices critical of Apple’s “Crush!” commercial on social media this week.

“The destruction of the human experience. Courtesy of Silicon Valley,” actor Hugh Grant wrote on the social media platform X, in a repost of Apple CEO Tim Cook’s sharing of the ad.

Some found the ad to be a telling metaphor of the industry today — particularly concerns about big tech negatively impacting creatives. Filmmaker Justine Bateman wrote on X that the commercial “crushes the arts.”

Experts added that the commercial marked a notable difference to marketing seen from Apple in the past — which has often taken more positive or uplifting approaches.

“My initial thought was that Apple has become exactly what it never wanted to be,” Vann Graves, executive director of the Virginia Commonwealth University’s Brandcenter, said.

Graves pointed to Apple’s famous 1984 ad introducing the Macintosh computer, which he said focused more on uplifting creativity and thinking outside of the box as a unique individual. In contrast, Graves added, “this (new iPad) commercial says, ‘No, we’re going to take all the creativity in the world and use a hydraulic press to push it down into one device that everyone uses.'”

In a statement shared with Ad Age on Thursday, Apple apologized for the ad. The outlet also reported that Apple no longer plans to run the spot on TV.

“Creativity is in our DNA at Apple, and it’s incredibly important to us to design products that empower creatives all over the world,” Tor Myhren, the company’s vice president of marketing communications, told Ad Age. “Our goal is to always celebrate the myriad of ways users express themselves and bring their ideas to life through iPad. We missed the mark with this video, and we’re sorry.”

Cupertino, California-based Apple unveiled its latest generation of iPad Pros and Airs earlier this week in a showcase that lauded new features for both lines. The Pro sports a new thinner design, a new M4 processor for added processing power, slightly upgraded storage and incorporates dual OLED panels for a brighter, crisper display.

Apple is trying to juice demand for iPads after its sales of the tablets plunged 17% from last year during the January-March period. After its 2010 debut helped redefine the tablet market, the iPad has become a minor contributor to Apple’s success. It currently accounts for just 6% of the company’s sales.

ALBUQUERQUE, New Mexico — The U.S. government is dedicating $60 million over the next few years to projects along the Rio Grande in southern New Mexico and West Texas to make the river more resilient in the face of climate change and growing demands.

The funding announced Friday by U.S. Interior Secretary Deb Haaland marks the first disbursement from the Inflation Reduction Act for a basin outside of the Colorado River system. While pressures on the Colorado River have dominated headlines, Haaland and others acknowledged that other communities in the West — from Native American reservations to growing cities and agricultural strongholds — are experiencing the effects of unprecedented drought.

Water users and managers can’t afford to waste one drop, Haaland said, sharing the advice her own grandmother used to give when she and her cousins would carry buckets of water to their home at Laguna Pueblo for cooking, cleaning and bathing.

“She was teaching us how precious water is in the desert,” Haaland said, standing among the cottonwoods that make up a green belt that stretches the length of the river from the Colorado-New Mexico border south into Texas and Mexico.

Haaland noted that parts of the river have gone dry through the Albuquerque stretch in recent years. In fact, a decades-long drought has led to record low water levels throughout the Rio Grande Basin.

“When drought conditions like this strike, we know it doesn’t just impact one community, it affects all of us,” she said, pointing to the importance of investing in water projects throughout the basin.

One of the longest rivers in North America, the Rio Grande provides drinking water for millions of people and supplies thousands of farmers with water for crops. Management of the river has sparked legal battles over the decades, with the most recent case pending before the U.S. Supreme Court as New Mexico, Texas and Colorado seek approval of a settlement that will help ensure they have more flexibility in the future.

U.S. Rep. Melanie Stansbury, a New Mexico Democrat, said improving sustainability along the Rio Grande will help the state meets obligations under a decades-old compact to deliver water downstream to Texas and ultimately Mexico.

Irrigation districts in southern New Mexico and El Paso, Texas, will work with the New Mexico Interstate Stream Commission, the National Fish and Wildlife Foundation and the U.S. Bureau of Reclamation to develop projects that will benefit the river and endangered species that inhabit the basin.

The work will range from capturing more stormwater runoff to improving existing infrastructure. Officials said the savings could result in tens of thousands of acre-feet of water. An acre-foot is roughly enough to serve two to three U.S. households annually.

In all, the Inflation Reduction Act provides $4 billion for mitigating drought in 17 western states, with the priority being the Colorado River Basin. However, the legislation also carved out $500 million for water management and conservation projects in other basins that are experiencing similar levels of long-term drought.

The U.S. Bureau of Reclamation said funding for other basins will be announced later this year, with the goal of putting the money to use over the next four years.

On the Rio Grande, prolonged drought and heavy reliance on groundwater pumping has reduced surface water supplies, resulting in decreased efficiency and lost wildlife habitat.

By capturing more stormwater and increasing storage, officials said they could recharge aquifers and reduce irrigation demands.

Some of that work already is happening in the Elephant Butte Irrigation District, which serves about 5,000 farmers in southern New Mexico. Near the farming village of Rincon, officials are working to slow down runoff and keep sediment from clogging channels that feed the river.

It’s among several projects that the irrigation district has proposed to federal officials to save water, protect communities from seasonal flooding and restore habitat.

Irrigation district manager Gary Esslinger and Samantha Barncastle, a water attorney who represents the district, traveled to Albuquerque on Friday to participate in a briefing with Haaland and other officials. They described the efforts as “re-plumbing” the West with irrigation and flood control systems that can accommodate the changing conditions.

“It’s quite a large vision,” Barncastle said, “but it’s what everyone should be doing — thinking big is the only way to resolve the climate crisis.”

SANFORD, Florida — With the start of hurricane season less than a month away, U.S. officials who predict, prepare for and respond to natural disasters had a message for Floridians on Friday: It’s not a matter of if a hurricane will hit, but when.

The 2024 hurricane season is expected to be busier than average. To ensure that people everywhere are prepared, officials visited residents in Sanford, a landlocked city in the middle of the Sunshine State.

Even if they don’t live on the coast, the officials told residents, they need to know the potential danger hurricanes pose to their property, such as flooding; and put together an emergency plan that includes a supply kit.

“Everybody in Florida is at risk,” said Michael Brennan, director of the National Hurricane Center.

As if to punctuate Florida’s vulnerability to damaging weather, wind gusts of 114 kph, just shy of hurricane force, were recorded early Friday in Tallahassee, where mangled metal and other debris from damaged buildings littered parts of the state’s capital city.

The officials in Sanford brought along two “hurricane hunter” planes used in the daredevil business of flying into the middle of storms to gather data about their intensity and direction.

The WP-3D, operated by the National Oceanic and Atmospheric Administration, and the WC-130J, flown by the U.S. Air Force Reserve, fly straight into the storms’ eyewall, usually three times during a flight. The aim of the hair-raising trips is to gather information that can help officials on the ground make decisions such as when to order people to evacuate.

NOAA’s propeller plane typically has 11-17 people on board during flights through hurricanes, including the crew and scientists. Since flights usually last eight hours, the crew members bring plenty of snack food, and there is a microwave, refrigerator and a hot plate for cooking more elaborate meals.

Although the rides can be very bumpy, sometimes they aren’t as turbulent as expected and crew members don’t realize that they already are in the eye of a hurricane, said William Wysinger, a NOAA flight engineer who has flown on a dozen missions through hurricanes.

“I liken it to riding an old wooden roller coaster during the worst of times,” Wysinger said.

The National Hurricane Center is predicting that the upcoming Atlantic and Gulf season, which runs from June 1 to November 30, will exceed the yearly average of seven tropical storms and seven hurricanes, and that three of the storms will be major. Not all hurricanes make landfall.

Floridians would be wise to remember 20 years ago when four hurricanes made landfall consecutively in just a matter of weeks, crisscrossing the state and carving paths of disaster, said David Sharp, meteorologist-in-charge at the National Weather Service in Melbourne, Florida.

“Many remember the ravages of the Hurricanes Charley, Frances, Ivan and Jeanne — blue tarps and pink insulation everywhere, along with displaced lives,” Sharp said. “Scars upon the land but also scars upon the psyche of our people.”

Hundreds of thousands of new residents have arrived in Florida since the last hurricane season, and it’s important that they know what to expect and how to prepare, said Robbie Berg, warning coordination meteorologist at the National Hurricane Center.

“Talk to your neighbors,” Berg said. “A lot of people in Florida have experienced these storms and they can help you through a storm if you’ve never been through one before.”
