Scientists disagree over Zika risk at Brazil's Olympics

One day after a top U.S. health official declared there was no public health reason to cancel or delay this summer's Olympics in Brazil, more than 150 scientists on Friday called for just that, saying the risk of infection from the Zika virus is too high. The scientists, many of them bioethicists, who signed an open letter published online to Dr. Margaret Chan, director-general of the World Health Organization. The letter urged that the Games, due to be held in Rio de Janeiro in August, be moved to another location or delayed.

NASA to make second attempt at inflating space station test module

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Astronauts aboard the International Space Station will try again on Saturday to inflate a novel experimental habitat after the fabric module failed to unfurl as planned earlier this week, NASA officials said on Friday. The Bigelow Expandable Activity Module, or BEAM, was unpacked 10 months later than expected due to launch delays, manufacturer Bigelow Aerospace told reporters on a conference call. The impact was likely most serious on the outer layers, said Lisa Kauke, BEAM deputy program manager at Bigelow.

Snorkeling Paradise Inside a Volcano Named Best US Beach

Hanauma Bay's new title represents the third in a streak of winners from the island of Oahu in the annual "Best Beaches" rankings, which are put together annually by Stephen Leatherman, a coastal researcher at Florida International University also known as "Dr. Beach." Leatherman ranks the top 10 public beaches around the United States based on factors ranging from sand softness and wind speeds to wave height and pollution. "Frankly, the United States is blessed with hundreds of wonderful beaches," Leatherman told Live Science.

Rosetta spacecraft finds key building blocks for life in a comet

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Scientists for the first time have directly detected key organic compounds in a comet, bolstering the notion that these celestial objects delivered such chemical building blocks for life long ago to Earth and throughout the solar system. The European Space Agency's Rosetta spacecraft made several detections of the amino acid glycine, used by living organisms to make proteins, in the cloud of gas and dust surrounding Comet 67P/Churyumov-Gerasimenko, scientists said on Friday. Glycine previously was indirectly detected in samples returned to Earth in 2006 from another comet, Wild 2.

Can Stomach Botox Injections Help People Lose Weight?

Doctors are considering a new use for Botox: The drug may help obese people lose weight, according to early research.

Vaping Could Make Medical Pot Healthier

A new type of smoking called "cannavaping" — using e-cigarettes for vaping cannabis — may help people use marijuana for medical reasons, according to a small, early study. Smoking conventional marijuana cigarettes may lead a person to inhale high amounts of the toxic contaminants that are released when marijuana is burned, the researchers said. In contrast, cannavaping might provide a way to avoid inhaling high levels of these contaminants, the researchers said.

Dead or Alive, Schrödinger's Cat Can Be in 2 Boxes at Once

Bizarrely behaving light particles show that the famous Schrödinger's cat thought experiment, meant to reveal the strange nature of subatomic particles, can get even weirder than physicists thought. "We are showing an analogy to Schrödinger's cat that is made out of an electromagnetic field that is confined in two cavities," said study lead author Chen Wang, a physicist at Yale University. The findings could have implications for cracking unsolvable mathematicalproblems using quantum computing, which relies on the ability of subatomic particles to be in multiple states at once, Wang said.
