Physicists control molecule for a millionth of a billionth of a second

Physicists control molecule for a millionth of a billionth of a second

Science
Sept. 7 (UPI) -- Using a microscope and its electrical current, physicists have found a way to manipulate and control a single molecule. The breakthrough happened by accident. In the lab, scientists were observing a basic chemical reaction under an electron microscope. Normally, when the current of the microscope is increased, the reaction happens faster. This time, it didn't. "This was data from an utterly standard experiment we were doing because we thought we had exhausted all the interesting stuff -- this was just a final check," Kristina Rusimova, physicist at the University of Bath, said in a news release. "But my data looked 'wrong' -- all the graphs were supposed to go up and mine went down." Scientists at Bath spent months trying to explain the anomaly. After repeating their exp...
Russian bombers intercepted off Alaska for second time this year

Russian bombers intercepted off Alaska for second time this year

World
Two Russian bombers were intercepted off the coast of Alaska recently -- the first flight by the country's bombers off the coast of Alaska since mid-May, according to North American Aerospace Defense Command (NORAD). The Russian planes, two TU-95 "Bear" long-range bombers, were flying in the Alaskan Air Defense Identification Zone (ADIZ), south of the Aleutian Islands, around noon Saturday when they were intercepted by two F-22 fighters. "The two Russian TU-95 bomber aircraft were intercepted and monitored by the F-22s until the bombers left the ADIZ along the Aleutian Island chain heading west," said the spokesperson. "At no time did the Russian bombers enter Canadian or United States sovereign airspace. Citing operational security, NORAD said it would not disclose how close the Rus...
Dallas Cowboys C Travis Frederick getting second opinion on spine

Dallas Cowboys C Travis Frederick getting second opinion on spine

Sports
Dallas Cowboys center Travis Frederick has been seeking more medical options to resolve the repeated stingers he has suffered in practice. Frederick met with a spine specialist prior to the Cowboys' preseason game over the weekend to determine if rest is the best course of treatment, the Dallas Morning News reported. One option that has not been ruled out, sources told the newspaper, is surgery. Cowboys owner Jerry Jones, in his weekly appearance on 105.3 The Fan, expressed hope that rest will allow Frederick's nerve irritation to subside. Frederick had contacted neck and spine specialist Dr. Robert Watkins in Los Angeles to make sure he was not dealing with a more severe injury. The four-time Pro Bowl center told ESPN that Watkins confirmed there were no additional issues and that ...

Watch live: Parker Solar Probe to make second launch attempt Sunday

Science
Aug. 11 (UPI) -- The Parker Solar Probe's first launch attempt was called off after a pair of technical glitches delayed launch proceedings. NASA's mission to touch the sun will make a second launch attempt on Sunday. "The launch of a United Launch Alliance Delta IV Heavy rocket carrying the Parker Solar Probe spacecraft was scrubbed today due to a violation of a launch limit, resulting in a hold," NASA said. "There was not enough time remaining in the window to recycle." The second launch window will open at 3:31 a.m. ET Sunday morning. NASA TV will provide live streaming coverage of the takeoff and initial flight through Earth's atmosphere. The rocket and probe will are ready and waiting on the Space Launch Complex-37 platform at Florida's Kennedy Space Center, part of the Cape Canavera...

Erika Christensen gives birth to second child at home

Entertainment
Aug. 11 (UPI) -- Parenthood alum Erika Christensen said she gave birth at home Friday with the help of her husband, Cole Maness. "It happened! It happened this morning. And it will go down in family history because babygirl's own, incredible Dad delivered her all by himself. My fault entirely as I didn't know she would come so quickly and didn't call the doc until far too late. He came straight over and arrived about one minute after she joined us in the world. Haha! My Mom too. You should've seen their faces when they walked in to hear her little wail," the actress wrote on Instagram. She included in her post a photo her mother snapped of her and Maness holding their newborn in their bed. "Meet Ms. Polly. She's chubby-cheeked and rosy and so beautiful," Christensen added. She married Man...
