Single atom alloy platinum-copper catalysts cut costs, boost green technology

A new generation of platinum-copper catalysts requiring very low concentrations of platinum in the form of individual atoms to cleanly and cheaply perform important chemical reactions is reported. The new catalysts could also facilitate broader adoption of environmentally friendly devices and processes.

Horn of Africa drying ever faster as climate warms

The Horn of Africa has become increasingly arid in sync with the global and regional warming of the last century and at a rate unprecedented in the last 2,000 years, according to new research. The scientists suggest that as global and regional warming continues, the eastern Horn of Africa — which includes Somalia, Djibouti and Ethiopia — will receive progressively less rain during the crucial ‘long rains’ season of March, April and May.

Blood clotting protein triggers immune attack on the brain

A new study from the Gladstone Institutes shows that a single drop of blood in the brain is sufficient to activate an autoimmune response akin to multiple sclerosis. This is the first demonstration that introduction of blood in the healthy brain is sufficient to cause peripheral immune cells to enter the brain, which then go on to cause brain damage.

Novel compound turns off mutant cancer gene in animals with leukemia

A compound discovered and developed by a team of Georgetown Lombardi Comprehensive Cancer Center researchers that halts cancer in animals with Ewing sarcoma and prostate cancer appears to work against some forms of leukemia, too. That finding and the team’s latest work was published in Oncotarget.

Ecotourism can put wild animals at risk, scientists say

Biologists who analyzed more than 100 research studies on how eco-tourism affects wild animals have concluded that the trips generally benefit the tourists much more than the animals — which may be placed at greater risk of losing their lives.

Apollo Photos Redux: The Story Behind the NASA Moon Pics Posted to Flickr

Apollo Photos Redux: The Story Behind the NASA Moon Pics Posted to FlickrThe addition of tens of thousands of the Apollo astronauts' moon photos to an online repository drew worldwide media interest this week, but lost in many of the headlines were the facts behind the four-decade-old photographs. Numerous news articles declared the photos were "never before seen" and attributed the upload to NASA, neither of which were true. "Contrary to some recent media reports, this Flickr gallery is not a NASA undertaking, but an independent one," said Kipp Teague, the founder of the Project Apollo Archive, in an introduction he wrote for the newly-added gallery.

It’s a Great Time to Spot the Elusive Planet Mercury: Here’s How

It's a Great Time to Spot the Elusive Planet Mercury: Here's HowOver next three weeks, we're going to be treated to a show being staged in the eastern twilight skies by three bright planets: Jupiter, Mars and Venus. Presently, Jupiter, Mars and Venus can be seen in the predawn sky stretched out in a diagonal line in that order, going from lower left to upper right. In fact, in the coming days Jupiter seems intent on having separate meetings with two his companions.

Computer science now top major for women at Stanford University

Stanford University's campus is seen from atop Hoover Tower in Stanford, CaliforniaBy Sarah McBride SAN FRANCISCO (Reuters) – Computer science has for the first time become the most popular major for female students at Stanford University, a hopeful sign for those trying to build up the thin ranks of women in the technology field. Based on preliminary declarations by upper-class students, about 214 women are majoring in computer science, accounting for about 30 percent of majors in that department, the California-based university told Reuters on Friday. If more women majored in technological fields like computer science, advocates say, that could help alleviate the dearth of women in engineering and related professions, where many practitioners draw on computer science backgrounds.

Scientists predict drier Horn of Africa as climate warms

By Megan Rowling BARCELONA (Thomson Reuters Foundation) – The Horn of Africa is becoming drier in step with global warming, researchers said on Friday, contradicting some climate models predicting rainier weather patterns in a region that has suffered frequent food crises linked to drought. A new study using a sediment core extracted from the Gulf of Aden found the East African region covering Somalia, Djibouti and Ethiopia has dried at an unusually fast rate over the past century. Lead author Jessica Tierney, an associate professor at the University of Arizona, told the Thomson Reuters Foundation the research team was confident the drying was linked to rising emissions of climate-changing greenhouse gases, and was expected to continue as the region heats up further.

The Origins of Religion: How Supernatural Beliefs Evolved

The vast majority of the U.S. population does not belong to the Catholic Church, and a growing percentage of Americans are not affiliated with any organized religion at all, according to a recent survey by the Pew Research Centers. This understanding of how the world worked facilitated the rapid decision-making process that humans had to go through when they heard a rustling in the grass.

Nestle spends $70 million on U.S. health science hub

A logo is pictured outside the Nestle Institute of Health Sciences at the EPFL in Ecublens near LausanneNestle's health science division is investing $70 million in a product technology center that will become the unit's new U.S. headquarters and research hub, the division said on Friday. The Bridgewater, New Jersey center will further Nestle's healthcare push as the Swiss company delves deeper into nutritional therapy and the high-margin medicines arena. Opening in 2016, the hub will relocate the unit's current research and development activities from Minneapolis and its current headquarters from nearby Florham Park.

ZomBee Watch helps scientists track honeybee killer

While scientists have documented cases of tiny flies infesting honeybees, causing the bees to lurch and stagger around like zombies before they die, researchers don’t know the scope of the problem. Now they are getting help in tracking the honeybee-killing parasite from ZomBee Watch, created in 2012 by John Hafernik, a biology professor at San Francisco State University.

Myth Busted: Conspiracy Theorists Do Believe Stuff ‘Just Happens’

Myth Busted: Conspiracy Theorists Do Believe Stuff 'Just Happens'The sheriff of Douglas County in Oregon where a mass shooting occurred on Oct. 2 is in hot water after the discovery that he posted a "Sandy Hook truther" video to Facebook in 2013. Contrary to popular opinion, the research finds, people who think conspiratorially aren't more likely to assume everything happens for a reason, rejecting the likelihood of random chance, than people who don't hold conspiracy beliefs. "What we show is that the psychology of conspiracy theories is located in a rather high level of cognition, perhaps at the level of beliefs and ideology and not at the level of a deeper personality or perception mode," said study researcher Sebastian Dieguez, a postdoctoral researcher at the University of Fribourg in Switzerland.
