The US House of Representatives has ordered an investigation into whether the Department of Defense experimented with ticks and other insects as biological weapons.In an amendment passed last week, the House calls for the Defense Department's Inspector General to look at whether any such experiments were done between the years 1950 and 1975.The amendment was introduced by New Jersey Rep. Chris Smith who said he was inspired to write it by "a number of books and articles suggesting that significant research had been done at US government facilities including Fort Detrick, Maryland, and Plum Island, New York, to turn ticks and other insects into bioweapons.""If true, what were the parameters of the program? Who ordered it?" Smith 749

The U.S. Food and Drug Administration has issued a warning against the use of teething necklaces, bracelets, and other jewelry used to relieve pain for children.This warning follows reports of a 7-month old child who was taken to the hospital after choking on the beads of a wooden bracelet and reports of an 18-month-old who was strangled to death by a teething necklace.“We know that teething necklaces and jewelry products have become increasingly popular among parents and caregivers who want to provide relief for children’s teething pain and sensory stimulation for children with special needs. We’re concerned about the risks we’ve observed with these products and want parents to be aware that teething jewelry puts children, including those with special needs, at risk of serious injury and death,” FDA Commissioner Scott Gottlieb said. The FDA provided the following 890

The University of Florida's band director says he was attacked Saturday night after the school's football game against the University of Miami in Orlando.The band was marching in uniform from the stadium to its buses following the game when a female Miami fan tried to cross the line of band students, University of Florida spokesman Steve Orlando told CNN, based on the director's account.That's when the band director, Jay Watkins, said he put his arm out to stop her and when he did, another person grabbed him from behind in a choke hold and threw him to the pavement, Orlando said."Jay suffered bumps and scrapes to his head and elbow," Orlando said. The director was doing "OK" Sunday, the spokesman added.No students were injured and a report has been filed with the Orlando Police Department, Orlando said, but no arrests have been made.Orlando police told CNN affiliate 890

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

The Wallace's giant bee is as big as a human thumb.That might be frightening to most people, but scientists were delighted when a team of researchers recently found it in Indonesia.It's the largest bee in the world, and scientists feared it might be extinct -- until now.A group of researchers made a stunning "rediscovery" of the elusive critter and took the first photos and video of a living Wallace's giant bee on January 25.The team -- composed of natural history photographer Clay Bolt, entomologist Eli Wyman, behavioral ecologist Simon Robson and ornithologist Glenn Chilton -- spent years studying the bee and slogged around in humid Indonesia forests for days before stumbling upon one.The rediscovery has renewed hope that more of the region's forests are home to the rare species.
