BOSTON (AP) — Colleges and universities are pushing back against the Trump administration’s decision to make international students leave the country if they plan on taking classes entirely online this fall. Harvard University and the Massachusetts Institute of Technology filed a lawsuit seeking to block the rule Wednesday, and other universities are promising to work with students to keep them in the country. The Trump administration says the directive will allow for proper social distancing on campuses. U.S. Immigration and Customs Enforcement notified colleges Monday that international students will be forced to leave the U.S. or transfer if their schools operate entirely online. 699

BRISTOL, Wis. -- For a fruit farmer who knew little about growing flowers, the pandemic was the perfect nudge to try something new. So, he plowed over his strawberry fields to plant a patch of sunshine and it’s grown beyond his wildest dreams.Scott Thompson’s family has been farming strawberries in Bristol, Wisconsin, for generations.“We've been around for a just about 100 years.”As the general manager of Thompson Strawberry Farms, he says they’ve adapted over time starting with apples and strawberries at first.“We've kind of morphed over the years where we have raspberries and pumpkins as well.”But this year, the pick-your-own farm traded the sweet fruits for something more picturesque.“This year is our first crack at pick your own sunflowers,” said Thompson.Even though Thompson knew very little about the bright yellow flower, he started out slow, until the pandemic hit and then had a thought.“This might be something that people might be really interested in. And so, I started planting. I did a small four-acre field then another four acres, then 10 acres. So, it just kind of grew, grew, grew.”He ended up planting not hundreds or thousands, but 2.2 million sunflower seeds across 22 acres of fields.“Having sunflowers is cool, but having a lot of sunflowers, that's really cool,” he said.For visitors like Sarah Akers and her 2-year-old son Xavier, it’s an eye-popping treat.“When they said how big it was, this is not what I was expecting,” said Akers. “It definitely is more impressive than what it sounds like when you just read about it.”It’s also a paradise for pollinators. Bees buzz from flower to flower. And with 15 fields, Thompson says it’s a great outing during the pandemic.“It's a perfectly natural social distancing activity,” said Thompson.The massive blooms have attracted visitors from all over the country. Debbie Berdinski, visiting from Alabama, was enthralled.“I love it. I think it's beautiful,” she said.And the decision to swap out strawberries for sunflowers has unexpectedly turned Thompson’s farm into his very own golden field of dreams.“You could really just go out and have a fun time and kind of forget about reality for a little bit,” he said. “Just enjoy being out here in this sea of yellow flowers.”And in a year like 2020, a little sunshine goes a long way. 2320

Bill Gates is sorry that he made it so annoying to log in to your computer.The billionaire Microsoft co-founder admitted Wednesday that the Control-Alt-Delete function used to start up Windows computers is an awkward maneuver."If I could make one small edit, I'd make that a single key," Gates said Wednesday on a panel at the Bloomberg Global Business Forum in New York City. 384

Breaking news update, posted at 2:19 p.m. ET] There were no signs of foul play in the death of a US Centers for Disease Control and Prevention epidemiologist, said Fulton County Chief Medical Examiner Dr. Jan Gorniak.The preliminary cause of death is drowning, Gorniak told reporters at a Thursday press conference, but the manner of death has not been determined. The investigation is ongoing.[Previous story, published at 1:46 p.m. ET]A body recovered this week from a river in Atlanta has been identified as the US Centers for Disease Control and Prevention epidemiologist who vanished in February, Atlanta Police Department spokesman Carlos Campos said Thursday.The remains of Timothy Cunningham, 35, were found Tuesday in the Chattahoochee River in northwest Atlanta, Campos said.A news conference is set for 2 p.m. ET Thursday. The Atlanta Police Department, the Fulton County Medical Examiner's Office and the Atlanta Fire Rescue Department will participate.Cunningham, of Atlanta, was last seen February 12, shortly after a CDC supervisor told him why he was being passed over for a promotion, police have said.The disappearance prompted a high-profile police search and a ,000 reward for clues. As days went on, internet rumors circulated that Cunningham's disappearance was tied to his alleged role as a flu vaccine whistle-blower. The rumors were debunked by police and his family.The CDC's director in mid-March issued a statement denying that Cunningham hadn't gotten a promotion and noting that he'd been promoted in July. Atlanta police responded by doubling down on their version of events, citing the CDC as the source of the information.The case perplexed investigators because Cunningham's keys, cell phone, credit cards, debit cards, wallet and all forms of identification were found in his house, along with his beloved dog.In announcing that his body had been found, authorities offered no hint about why he disappeared.Co-workers told authorities that Cunningham had been "obviously disappointed" on the morning of February 12, when he learned why he wasn't getting the promotion he'd hoped for, police have said. He left work quickly, saying he felt ill, they said.Earlier that morning, at 5:21 a.m., Cunningham's mother had received a text message from him, she has said. "Are you awake?" her son asked. But her phone was on silent mode. "I wish I had that opportunity to answer that text," she said later.Cunningham also called his mother at 9:12 a.m. that day, but she did not answer, Atlanta police have said. He did not leave a message.  2582

Beyond the beaches of the world, lies the potential for oceans of energy."I'm very excited about this because it's a very renewable energy-based technology,” said Professor Bruce Logan of Penn State University.Logan and university researchers recently created a device that removes salt from seawater in a cheaper way, allowing that water to then be used to create a renewable form of hydrogen fuel.“There's a lot of interest in renewable hydrogen,” Logan said. “Most of the hydrogen made today is made from fossil fuels, and so, we're interested in making that hydrogen from water.”That involves splitting water molecules into oxygen and hydrogen. The problem? Seawater also has salt, which needs to be removed first and that’s expensive to do.However, the “seawater electrolyzer” that Logan and his team worked on takes care of that issue cheaply by using a special membrane and without requiring expensive desalination plants. The findings were recently published in the Journal of Energy and Environmental Science.“Hydrogen is a great fuel,” he said. “It's been examined as a fuel for many decades now.”About 97 percent of all the water on earth is in the ocean, which means if it could be used efficiently to make hydrogen fuel, it could be a game-changer.“As we look to de-carbonize our fossil fuel infrastructure, we also can use it primarily for heavy-duty vehicles,” Logan said. “Airbus is looking to actually make airplanes that fly on hydrogen.”For now, though, their device would need to be scaled-up to a much larger version.“There are many nations and companies and nations across the world looking to do this. One of the biggest proposed hydrogen plants is in Saudi Arabia -- billion,” Logan said. “I would hope to convince them that it might be cheaper and better to use seawater directly, you know, in a system like this.”It’s a possibility that might one day create a bridge between our energy needs on land and the power in the sea. 1962
