NASA Opens Research Portal for Scientists

NASA has a new web portal highlighting the research funded by the agency, and promises to put all its peer-reviewed studies online in less than a year. The research will be available on PubSpace, an archive maintained by the U.S. Department of Health & Human Services. There is no charge to register, and the data can be downloaded and analyzed, NASA officials said.

Flying Cockroaches! Heat Sends Your Favorite Pests Soaring

"Cockroaches, like all insects, are cold-blooded, meaning their activity rate increases with temperature," said Jules Silverman, an entomologist and professor at North Carolina State University, in an interview with Live Science. This also means that the species of cockroach that are able to fly (and most of them are capable) are probably more likely to do so in warmer places, said Silverman. If you think that flying cockroaches are especially horrific, you probably live somewhere with a colder climate and a denser human population.

Exxon, GT find way to cut carbon emissions for chemicals: Science

Exxon Mobil and Georgia Tech researchers published findings of a breakthrough in the journal Science on Thursday, saying they had devised a way to slash carbon emissions from chemicals manufacturing by using reverse osmosis instead of heat to separate molecules. Reverse osmosis, which has been widely used for decades in desalination plants that turn seawater into drinking water, has long been seen as having applications for the oil and chemicals industry. Now researchers have finally come up with a specially treated polymer that can serve as the semipermeable membrane needed to do reverse osmosis for chemicals manufacturing at room temperature.

Scientists to probe ways of meeting tough global warming goal

By Alister Doyle OSLO (Reuters) - Scientists on Thursday set the outlines of a report on how to restrict global warming to a limit agreed last year by world leaders - even though the temperature threshold is at risk of being breached already. The U.N.-led study, due to be published in 2018 as a guide for governments, will look into ways of cutting greenhouse gas emissions to cap the rise at 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels. Thelma Krug, a Brazilian scientist who led the four-day meeting in Geneva, said it will also cast the fight against climate change as part of a wider struggle to end poverty and ensure sustainable growth.

16th-Century Shipwrecks Found Amid Rocket Debris Off Florida Coast

It's relatively common to find debris from rocket launches in the waters off Cape Canaveral in Florida, but divers exploring the seabed recently uncovered artifacts from an age of exploration long before America's space program: 22 cannons and a marble monument in what they think are three 16th-century Spanish shipwrecks. The finds include three ornate bronze cannons — two that are 10 feet (3 meters) long and one that is 7 feet (2 m) long — and the marble monument, engraved with the coat of arms of the king of France, which has been identified from the manifest of a 1562 expedition to Florida by the French navigator and colonialist Jean Ribault. Robert Pritchett, chief executive of the Florida-based company Global Marine Exploration, which explored the wrecks in May and June, told Live Science that it was initially thought that the newfound wrecks might include Ribault's two "lost ships," which sank during a storm in 1565, a few years after the voyage from France…

What's Causing Louisiana's Historic Flooding?

Tremendous downpours have inundated parts of Louisiana over the last few days, resulting in disastrous flooding and forcing thousands of people from their homes. An "inland sheared tropical depression" is how the National Oceanic and Atmospheric Administration's National Weather Service (NWS) described the heavy rain event on Friday morning (Aug. 12). The NWS also noted that the moisture content in the atmosphere was close to an all-time record for the area, even higher than observations during some tropical cyclones.

Ancient Bling: Exquisite Jewelry Found in Tomb of Chinese Woman

Around 1,500 years ago, at a time when China was divided, a woman named Farong was laid to rest wearing fantastic jewelry, which included a necklace of 5,000 beads and "exquisite" earrings, archaeologists report. Her tomb was discovered in 2011 in Datong City, China, by a team of archaeologists with the Datong Municipal Institute of Archaeology who were surveying the area before a construction project. Farong's tomb was dug into the ground, and her skeleton (which is now in poor condition) was found lying in a coffin archaeologists said.

No, That Ancient Mausoleum Is Not the 'World's 1st Pyramid'

The discovery of a 3,000-year-old pyramid-shaped mausoleum in Kazakhstan has gone viral over the past 24 hours, with several media outlets proclaiming the structure to be the world's first pyramid. The mausoleum is 6.6 feet (2 meters) high and about 49 by 46 feet (15 by 14 m) long, said Viktor Novozhenov, an archaeologist with the Saryarka Archaeological Institute at Karaganda State University in Kazakhstan who helped excavate the mausoleum.

Coral Reefs Flourish Thanks to … Fish Pee?

Getting peed on is a good thing, at least for coral reefs, scientists have found. This, combined with nitrogen excreted from their gills, is crucial for coral reef survival and growth, according to recent studies. When scientists studied areas with heavy fishing, they found that almost half of the key nutrients needed to maintain a healthy reef ecosystem were missing.
