Using Microscopic Bugs to Save the Bees
October 27, 2014 02:49 PM - Brigham Young University

For decades, honeybees have been battling a deadly disease that kills off their babies (larvae) and leads to hive collapse. It’s called American Foulbrood and its effects are so devastating and infectious, it often requires infected hives to be burned to the ground. Treating Foulbrood is complicated because the disease can evolve to resist antibiotics and other chemical treatments. Losing entire hives not only disrupts the honey industry, but reduces the number of bees for pollinating plants. Now an undergraduate student at BYU, funded by ORCA grants, has produced a natural way to eliminate the scourge, and it’s working: Using tiny killer bugs known as phages to protect baby bees from infection.

Ebola - vaccines under development show promise

Not everyone who contracts the Ebola virus dies, the survival rate is around 30% suggesting that some kind of immunity to the disease is possible. Experimental treatments and vaccines against Ebola exist but have not yet been tested in large groups for safety and efficacy (phase 2 trials). 

The International Union of Immunology Societies (IUIS) published a statement today in its official journal, Frontiers in Immunology calling for urgent and adequate funding of vaccine candidates in clinical trials and speedy implementation of immunisation in African countries.

Which Form of Energy is the Cheapest?
October 16, 2014 10:47 PM - Kevin Mathews, Care2

Which kind of power is the cheapest? Listen to energy companies, and they'll insist that traditional forms like gas and coal are the way to go. Of course, they have money invested in keeping the existing systems in business. That's why the European Union commissioned an independent analysis to study the topic. According to the report, wind energy is the most cost-efficient way to supply power. When proponents of non-renewable energy point to costs, they intentionally overlook the overall economic impact that polluting causes. Once experts start to calculate the costs associated with public health and climate change that coincide with burning coal and gas, the true cost is far higher than initially reported. It's both irresponsible and shortsighted to ignore these environmental and health consequences from the equation.

Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University

If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.

Lawrence Livermore finds ocean warming underestimated by past analyses
October 6, 2014 07:32 AM - Anne M Stark, LLNL

Using satellite observations and a large suite of climate models, Lawrence Livermore scientists have found that long-term ocean warming in the upper 700 meters of Southern Hemisphere oceans has likely been underestimated. "This underestimation is a result of poor sampling prior to the last decade and limitations of the analysis methods that conservatively estimated temperature changes in data-€sparse regions," said LLNL oceanographer Paul Durack, lead author of a paper appearing in the October 5 issue of the journal Nature Climate Change.

How do we know an extreme weather event might be caused by climate change?
October 2, 2014 06:49 AM - CHRISTOPHER JOYCE, NPR

Nowadays, when there's a killer heat wave or serious drought somewhere, people wonder: Is this climate change at work? It's a question scientists have struggled with for years. And now there's a new field of research that's providing some answers. It's called "attribution science" — a set of principles that allow scientists to determine when it's a change in climate that's altering weather events ... and when it isn't. The principles start with the premise that, as almost all climate scientists expect, there will be more "extreme" weather events if the planet warms up much more: heat waves, droughts, huge storms.

NASA's GRAIL mission sheds light on the origin of the Procellarum basin on the Moon
October 1, 2014 02:24 PM - Jennifer Chu | MIT News Office

New data obtained by NASA's GRAIL mission reveals that the Procellarum region on the near side of the moon - a giant basin often referred to as the "man in the moon" - likely arose not from a massive asteroid strike, but from a large plume of magma deep within the moon's interior. The Procellarum region is a roughly circular, volcanic terrain some 1,800 miles in diameter - nearly as wide as the United States. One hypothesis suggested that it was formed by a massive impact, in which case it would have been the largest impact basin on the moon. Subsequent asteroid collisions overprinted the region with smaller - although still large - basins.

Dog waste contaminates our waterways
October 1, 2014 10:50 AM - American Chemical Society

Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria — including antibiotic-resistant strains — that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern, according to a report in the ACS journal Environmental Science & Technology.

Cornell finds molecule in space that connotes life origins
September 26, 2014 05:36 PM - Cornell University via EurekAlert

Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule — one with a branched structure — contained within a giant gas cloud in interstellar space. Like finding a molecular needle in a cosmic haystack, astronomers have detected radio waves emitted by isopropyl cyanide. The discovery suggests that the complex molecules needed for life may have their origins in interstellar space.
