Mercury Mystery Solved: Scientists Decode Planet's Weird Surface

Using data from NASA's MESSENGER spacecraft — which orbited Mercury from 2011 to 2015 — scientists at the Johnson Space Center took a closer look at how a mix of young and old terrain could develop. "We think that planets start hot and almost completely melt," Asmaa Boujibar, NASA postdoctoral fellow and lead author of the study, said in the statement. The researchers simulated what Mercury's interior might be like to try to work out the cause of the vast differences seen on the planet's surface.

SpaceX signs first customer for used Falcon rocket

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Elon Musk's SpaceX has signed its first customer to use a previously flown rocket, with launch planned for later this year, the companies said on Tuesday. The launch for Luxembourg-based satellite operator SES SA will mark the first commercial reuse of a Falcon 9 rocket, which is crucial to efforts by technology entrepreneur Musk's Space Exploration Technologies Corp to reduce the cost of space launches. SpaceX President Gwynne Shotwell previously said the company was targeting a 30 percent discount for launches aboard previously flown rockets, which would bring the price down to about $43 million per flight, a fraction of what competitors charge.

Curious radio signal stirs talk of extraterrestrials

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A curious radio signal picked up by a Russian telescope is probably not a transmission from an extraterrestrial civilization, but astronomers in California are taking a second look anyway, the SETI Institute said on Tuesday. A group of Russian astronomers last year detected what appeared to be a non-naturally occurring radio signal in the general location of a star system 94 light-years from Earth.

How Does Listeria Get into Veggies?

About 30,000 cases of precut vegetables are being recalled in many Southeastern states because they could be contaminated with Listeria. This week, the food manufacturer Country Fresh announced a recall of several of its vegetable products — including precut onions, mushrooms and peppers — after one of its products being sold in a Georgia grocery store tested positive for Listeria bacteria. The recall affects products sold at a number of grocery stores — including Walmart, Harris Teeter and Winn-Dixie — in nine Southern states (Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee and Virginia).

The Perks of Being a Twin May Include a Longer Life

Researchers found that identical twins in Denmark tended to live longer than fraternal twins in that country, while both types of twins typically outlived men and women in Denmark who were not twins. The researchers said they suspect that the longevity boost in twins results from the social bonds between the two siblings, Sharrow said. The scientists looked at data on more than 2,900 same-sex pairs of twins who were born in Denmark between 1870 and 1900, limited to pairs in which both twins had survived to at least the age of 10.

Watch Out for Wasps: Insect Sting Causes Man's Stroke

People's reactions to getting stung by a bee or wasp can range from a feeling bit of pain to a suffering a deadly allergy reaction — and now a recent report of one man's case highlights a particularly rare complication of a sting: having a stroke. A stroke occurs when a part of a person's brain is starved of blood, typically because of a blood clot or a leaky blood vessel. Dr. Michael DeGeorgia, who treated the man, told Live Science that he had never before seen a case where a stroke was caused by a wasp sting.

Is a Blue Fire Tornado the Future of Oil Spill Cleanup?

A blue fire tornado sounds like it could be an alarming natural disaster, but this phenomenon could actually offer a way to burn fuel with reduced carbon emissions, a new study finds. A fire tornado, or fire whirl, can occur during urban and wildland fires, threatening life, property and the surrounding environment. Traditional, yellow fire whirls gain their color from radiating soot particles, according to study co-author Elaine Oran, a professor of engineering at the University of Maryland.

Kenya close to ending drought crises, says local scientist award winner

By Katy Migiro NAIROBI (Thomson Reuters Foundation) - Kenya is on its way to breaking the devastating cycle of drought, poverty and hunger over the next decade, a leading scientist said as he was named winner of a prestigious award. Kenyan scientist Andrew Mude won the 2016 Norman Borlaug Award for Field Research and Application on Tuesday for developing livestock insurance, using state-of-the-art technologies, for herders in East Africa's drylands. "I am confident that with insurance and the related complementary services, the boom and bust cycle will come to an end," said Mude, principal economist at the Nairobi-based International Livestock Research Institute (ILRI).
