Tornadoes kill an average of 60 people a year in the United States, according to the National Oceanic and Atmospheric Administration. Many of the deaths are caused by flying or falling debris.They are most common in the Central Plains and southeastern United States.Here are the 10 deadliest tornadoes to touch down in the United States, according to 363

The Trump administration has confirmed that 1,556 more migrant children than previously reported were separated from their families at the southern border.These separations happened before the administration's “zero tolerance” policy was officially in place. A judge ordered an end that controversial policy in June 2018. Thursday's announcement of these additional cases brings the total to at least 413

Think of it as January in November.A blast of Arctic air is sweeping the eastern two-thirds of the United States, moving millions to bundle up against below-freezing temperatures much earlier than usual and putting people as far south as Texas at risk for snow and ice.About 70% of the US population is expected to see temperatures at or below freezing by Wednesday morning, and hundreds of records are expected to fall with temperatures generally 20 to 40 degrees below normal.Travel could be tricky especially in 15 states from Texas to New England, where snow and ice could accumulate Tuesday. Elsewhere, parts of the Deep South are under freeze watches, warnings or advisories, including South Texas and the Florida Panhandle. 742

Those who live in El Paso, Texas—a city that lives on the U.S. and Mexico borders—describes their home as a loving place.“Everybody knows everybody, seems that way,” says resident Ruben Vuentes. Vuentes says the people of El Paso are not close-minded. Resident Alicia Brown shares the same sentiment. She says she’s never felt out of place because of the color of her skin. “There’s no racism here,” she says. “I don’t feel it. I’ve never felt it in all my life.”Now, those living in the close-knit community are trying to heal after a gunman killed 22 people and injured dozens of others Saturday at a local Walmart. Police say the 21-year-old white, male suspect is believed to be the author of a racist, anti-Hispanic 2,300-word document found online. Police say the manifesto was filled with white nationalist language and blamed immigrants for taking away jobs. El Paso has found itself at the center of the Trump administration’s hardline stance on immigration due to its proximity to the border. Marisa Limon Garza with the Hope Border Institute says the community is family and that include El Pasoans and Mexican nationals, just across the border in Juarez. “These border lands, these fences, these structures, are things that were imposed on us,” she says. But this has been a binational community for so long, and it’s one we find great beauty in.”It’s a melting pot of immigrants and Mexican nationals, and the community sees it as an asset. “This city is surviving because of the people coming from Juarez, says Brown. “What people don’t realize is they are part of this economy. The people that were at Walmart, they were shopping for clothes, school supplies, just like all of us.”Brown says when the shooting happened, she did worry the community—this family—might have been shattered. But that isn’t the case.“Because really, he didn’t; he brought us together. He united us,” Brown says of the shooter. 1931

The results are finally in for the first chocolate chip cookie bake-off in space.While looking more or less normal, the best cookies required two hours of baking time last month up at the International Space Station. It takes far less time on Earth, under 20 minutes.And how do they taste? No one knows. Still sealed in individual baking pouches and packed in their spaceflight container, the cookies remain frozen in a Houston-area lab after splashing down two weeks ago in a SpaceX capsule. They were the first food baked in space from raw ingredients.The makers of the oven expected a difference in baking time in space, but not that big.“There’s still a lot to look into to figure out really what’s driving that difference, but definitely a cool result,” Mary Murphy, a manager for Texas-based Nanoracks, said this week. “Overall, I think it’s a pretty awesome first experiment.”Located near NASA’s Johnson Space Center, Nanoracks designed and built the small electric test oven that was launched to the space station last November. Five frozen raw cookies were already up there.Italian astronaut Luca Parmitano was the master baker in December, radioing down a description as he baked them one by one in the prototype Zero G Oven. The first cookie — in the oven for 25 minutes at 300 degrees Fahrenheit (149 degrees Celsius) — ended up seriously under-baked. He more than doubled the baking time for the next two, and the results were still so-so.The fourth cookie stayed in the oven for two hours, and finally success. “So this time, I do see some browning,” Parmitano radioed. “I can’t tell you whether it’s cooked all the way or not, but it certainly doesn’t look like cookie dough any more.”Parmitano cranked the oven up to its maximum 325 degrees F (163 degrees C) for the fifth cookie and baked it for 130 minutes. He reported more success.Additional testing is required to determine whether the three returned cookies are safe to eat.As for aroma, the astronauts could smell the cookies when they removed them from the oven, except for the first.That’s the beauty of baking in space, according to former NASA astronaut Mike Massimino. He now teaches at Columbia University and is a paid spokesman for DoubleTree by Hilton. The hotel chain provided the cookie dough, the same kind used for cookies offered to hotel guests. It’s offering one of the space-baked cookies to the Smithsonian Institution’s National Air and Space Museum for display.“The reminder of home, the connection with home, I think, can’t be overstated,” Massimino said. “From my personal experience ... food is pretty important for not just nutrition but also for morale in keeping people connected to their home and their Earth.”Eating something other than dehydrated or prepackaged food will be particularly important as astronauts head back to the moon and on to Mars.Nanoracks and Zero G Kitchen, a New York City startup that collaborated with the experiment, are considering more experiments for the orbiting oven and possibly more space appliances. What’s in orbit now are essentially food warmers.There’s an added bonus of having freshly baked cookies in space.“We made space cookies and milk for Santa this year,” NASA astronaut Christina Koch tweeted.___The Associated Press Health and Science Department receives 3315
