A new report by the United Nations Environment Programme (UNEP) says that crops such as wheat and maize are generating more potential toxins as a reaction to protect themselves from extreme weather.

The other three deaths were climbers, all suspected of having altitude sickness. So what makes Mount Everest such a dangerous place?

Nile crocodiles — American crocodiles' larger, more aggressive cousins from the African continent — have been identified in the wild in southern Florida for the first time, according to a new study. The scientists caught three young crocodiles — one of which was captured on the porch of a Miami home — and, through genetic analysis of tissue samples, confirmed that they were invasive Nile crocodiles, connecting them to crocodile populations in South Africa.

The finding turns an old theory on its head, showing that early marine reptiles didn't evolve slowly after the end-Permian extinction. The extinction wiped out about 96 percent of all marine species, largely due to climate change, volcanic eruptions and rising sea levels, the researchers said.

The scans were made in the Abri Faravel, a small rock overhang in the southern French Alps. In 2010, researchers found paintings decorating the ceiling of the rock shelter, consisting of parallel lines as well as what look like two animals facing each other.

Before you dive in, you should probably check with the facility about its inspection status, health officials with the Centers for Disease Control and Prevention (CDC) warn. According to a study published online May 20 in the CDC's Morbidity and Mortality Weekly Report, thousands of venues in the U.S. where people swim or wade in treated water — public pools, hot tubs, water playgrounds and parks — had to be closed in 2013 due to health and safety violations.

For psychologists studying family dynamics and child development, the new finding that disagreements can be meaningful is important, said study researcher Thomas Schofield, a psychologist at Iowa State University. In any relationship, people don't always see eye-to-eye, Schofield told Live Science. "We were assuming that only the information that shows up across every single [observer] is to be trusted, but that's not really how we behave in real life," Schofield said. Read More »

Australian scientists said in March just seven percent of the entire Great Barrier Reef had avoided any damage as a result of bleaching, and they held grave fears particularly for coral on the northern reef. After further aerial surveys and dives to access the damage across 84 reefs in the region, Australian scientists said the impact of the bleaching is more severe than they had expected.

The Southern Ocean off Antarctica may be among the last places on Earth to feel the impact of man-made climate change, with a lag of centuries to affect waters emerging from up to 5,000 metres (16,000 ft) deep, the U.S. study said. Many people who doubt mainstream scientific findings that human use of fossil fuels is warming the planet often point to the paradox of expanding winter sea ice off Antarctica in recent decades and a rapid shrinking of ice in the Arctic.

"The return on investment based on the current commercial model is not really commensurate with the amount of effort you have to put into it," said David Payne, who heads GlaxoSmithKline PLC's antibiotics drug group. Other pharmaceutical companies expressed a similar sentiment. Read More »

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.

(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.

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. Read More » Neanderthals Likely Built These 176,000-Year-Old Underground Ring Structures About 40,000 years before the appearance of modern man in Europe, Neanderthals in southwestern France were venturing deep into the earth, building some of the earliest complex structures and using fire. That's according to new research that more precisely dated bizarre cave structures built from stalagmites, or mineral formations that grow upward from the floor of a cave. Scientists discovered about 400 stalagmites and stalagmite sections that were collected and stacked into nearly circular formations about 1,100 feet (336 meters) from the entrance of Bruniquel Cave, which was discovered in 1990.

(Reuters) - Astronauts aboard the International Space Station on Saturday slowly inflated an experimental fabric module that may provide a less expensive and safer option for housing crews during long stays in space, a NASA TV broadcast showed. An initial attempt to unfurl the module on Thursday failed, most likely because of friction within the module's layers of fabric, foam and reinforced outer covering, NASA said. "It's a learning process," said NASA mission commentator Dan Huot. Read More »
