Doing exercise may counteract some of alcohol’s deadly effects

It’s good news for those equally at home on a treadmill or at a bar. Regular exercise seems to cancel out some of the risk of death that is linked to alcohol.

High alcohol intake is associated with fatal heart disease, stroke, and at least seven types of cancer.

An analysis of people over the age of 40 has found that people who do the recommended amount of physical activity a week – 150 minutes of aerobic exercising – but drink more than the UK weekly recommended limit are less likely to die than people who drink the same amount but exercise less.

Zika vaccine trials begin – but fears remain over virus’s impact

There’s finally some progress in the fight against Zika. A vaccine is being given to 160 people in Zika-hit Puerto Rico, and a preliminary study has identified two existing drugs that seem to protect human brain cells from the virus.

The vaccine, developed by Inovio Pharmaceuticals, contains a synthetic DNA fragment similar to one in the virus itself. The company hopes that people who receive it will develop immune protection against Zika.

Astronomers Don’t Think That So-Called SETI Signal Is Aliens

This weekend, a group of astronomers made many, many headlines after giving a presentation about “a strong signal in the direction of HD164595.” HD164595 is a Sun-like star 94 light-years away, and with the RATAN-600 radio telescope in Zelenchukskaya, Russia, pointed in its direction, the astronomers picked up a blast of radio waves about 4.5 times stronger than background static. Maybe aliens? they suggested. We should investigate.

The Defense Department for the second year in a row sent one of its top directors to DEF CON in Las Vegas this month, but it wasn’t for recruiting purposes.

So what was Frank DiGiovanni, director of force training in DoD’s Office of the Assistant Secretary of Defense for Readiness, doing at DEF CON? “My purpose was to really learn from people who come to DEF CON … Who are they? How do I understand who they are? What motivates them? What sort of attributes” are valuable to the field, the former Air Force officer and pilot who heads overall training policy for the military, says.

SETI has observed a “strong” signal that may originate from a Sun-like star

It remains only the barest of probabilities that astronomers have just found evidence of extraterrestrial, intelligent life. Nevertheless, in the community of astronomers and other scientists who use radio telescopes to search the heavens for beacons of life there is considerable excitement about a new signal observed by a facility in Russia.

China has launched the world's first satellite dedicated to testing the fundamentals of quantum communication in space. The $100m Quantum Experiments at Space Scale (QUESS) mission was launched today from the Jiuquan Satellite Launch Center in northern China at 01:40 local time. For the next two years, the craft – also named "Micius" after the ancient Chinese philosopher – will demonstrate the feasibility of quantum communication between Earth and space, and test quantum entanglement over unprecedented distances.

Martians Might Be Real. That Makes Mars Exploration Way More Complicated

History will note that the guy who discovered liquid water on Mars was an undergraduate at the University of Arizona, a 20-year-old who played guitar in a death-metal band and worked in a planetary science lab. One day, while comparing different satellite images of a single Martian crater taken at various times of year, he noticed something odd: a set of dark streaks in the soil that grew in the Martian summer and shrank in the winter. They seemed to flow down the crater’s slope, like a spill.

CERN confirms: Hints of hypothetical particle have disappeared

Toward the end of last year, the people behind the Large Hadron Collider announced that they might have found signs of a new particle. Their evidence came from an analysis of the first high-energy data obtained after the LHC's two general-purpose detectors underwent an extensive upgrade. While the possible new particle didn't produce a signal that reached statistical significance, it did show up in both detectors, raising the hope that the LHC was finally on to some new physics.

Neuroscientists Still Don’t Know Why Music Sounds Good

Your taste in music is weird. Maybe you just can’t stop listening to that power ballad, or you’ve wondered about your bewildering weakness for yodeling. And maybe, just maybe, nobody understands your all-consuming obsession with Steely Dan, the greatest band of all time.
