New research suggests climate change may have contributed to extinction of Neanderthals
A researcher at the University of Colorado Denver has found that Neanderthals in Europe showed signs of nutritional stress during periods of extreme cold, suggesting climate change may have contributed to their demise around 40,000 years ago.

Brain imaging links Alzheimer's decline to tau protein
Using a new imaging agent that binds to the Alzheimer's-linked tau protein and makes it visible in positron emission tomography scans, scientists at Washington University School of Medicine in St. Louis have shown that measures of tau are better markers of the cognitive decline characteristic of Alzheimer's than measures of amyloid beta seen in PET scans.

Fossil dog represents a new species, Penn paleontology grad student finds
A doctoral student at the University of Pennsylvania has identified a new species of fossil dog. The specimen, found in Maryland, would have roamed the coast of eastern North America approximately 12 million years ago, at a time when massive sharks like megalodon swam in the oceans.

NSF grant to enable research computing infrastructure dedicated to science and engineering
A $500,000 grant from the National Science Foundation will enable FAU to install networking infrastructure to amplify its ability to conduct data-intensive science and engineering research. Referred to as a DMZ, the network isolates research traffic from other university network operations to achieve high performance. With a tenfold increase in capacity, the DMZ will span the Boca Raton, Jupiter, and Harbor Branch campuses, as well as Scripps Florida and the Max Planck Florida Institute.

Silk stabilizes blood samples for months at high temperatures
Researchers at Tufts University have stabilized blood samples for long periods of time without refrigeration and at high temperatures by encapsulating them in air-dried silk protein. The technique, published online in PNAS, has broad applications for clinical care and research that rely on accurate analysis of blood and other biofluids.

Big thinking in small pieces: Computer guides humans in crowdsourced research
Getting a bunch of people to collectively research and write a coherent report without any one person seeing the big picture may seem akin to a group of toddlers producing Hamlet by randomly pecking at typewriters. But Carnegie Mellon University researchers have shown it actually works pretty well -- if a computer guides the process. Their system, called the Knowledge Accelerator, uses a machine-learning program to sort and organize information uncovered by individuals focused on just a small segment of the larger project.

Radioactive isotopes reveal age of oil and gas wastewater spills
A Duke study shows that radium isotopes in soils can be used to determine the age of oil and gas wastewater spills. Three new isotopic age-dating methods developed by the team could be useful for identifying the source of a spill where it's not certain if contamination stems from recent unconventional oil and gas drilling or from older, conventional oil and gas operations in the same watershed.

Hijacked cell division helped fuel rise of fungi
The more than 90,000 known species of fungi may owe their abilities to spread and even cause disease to an ancient virus that hijacked their cell division machinery, researchers report. Over a billion years ago, a viral protein invaded the fungal genome, generating a family of proteins that now play key roles in fungal growth. The research could point to new antifungals that inhibit cell division in fungi but not in their plant or animal hosts.

Heartburn drug damages blood vessel cells in lab finding
A commonly used heartburn medication caused blood vessel cells to age faster in laboratory testing. These findings could help explain recent reports linking long-term use of heartburn medication to several serious illnesses, including heart disease, kidney disease and dementia. Clinical studies still are necessary to determine if the drugs damage blood vessel cells within the body.

A team of more than 80 mathematicians from 12 countries has begun charting the terrain of rich, new mathematical worlds, and sharing their discoveries on the Web. The mathematical universe is filled with both familiar and exotic items, many of which are being made available for the first time. The project provides a new tool for several branches of mathematics, physics, and computer science.

New Oligocene primates from China highlight key evolutionary period
In a study published May 6 in Science, Dr. Ni Xijun, Institute of Vertebrate Paleontology and Paleoanthropology and his team reported the discovery of a diverse primate fauna from the early Oligocene of southern China. Asian and Afro-Arabian primate faunas responded differently to EOT climatic deterioration, indicating that the EOT functioned as a critical evolutionary filter constraining the subsequent course of primate evolution across the Old World.

UGA study finds Saharan dust affects marine bacteria, potential pathogen Vibrio
Iron can be hard to hard to come by in open marine waters -- except each summer, when atmospherically transported dust from north Africa's Sahara Desert provides pulses of biologically important nutrients, including iron, to the tropical marine waters of the Caribbean and southeastern US. University of Georgia researchers found Vibrio bacteria respond rapidly to this influx of iron-rich Saharan dust, leading to large blooms of the potentially harmful bacteria.

UCI sleuths search the seas for soot
UCI scientists have taken water samples from the north Pacific, north and south Atlantic, and Arctic oceans in search of repositories of black carbon, soot from burning biomass and diesel engines, among other sources. There is considerably less of the material than expected, and it exists in at least two varieties, a younger pool near the ocean's surface that cycles on a centennial scale and an ancient reserve that remains stable for millennia.

Shellfish response to ocean acidification depends on other stressors
A study of California mussels, a key species in the rocky intertidal ecosystems of the West Coast, indicates that the effects of ocean acidification will vary from place to place along the coast depending on a range of interacting factors. Researchers found that the ability of mussels to cope with more acidic conditions depends largely on how much food is available to them, and both factors vary from place to place.
