Kung fu stegosaur: Lethal fighters when necessary


October 21st, 2014         by Latest Science News -- ScienceDaily

Stegosaurs might be portrayed as lumbering plant eaters, but they were lethal fighters when necessary, according to paleontologists who have uncovered new evidence of a casualty of stegosaurian combat. The evidence is a fatal stab wound in the pubis bone of a predatory allosaur. The wound -- in the conical shape of a stegosaur tail spike -- would have required great dexterity to inflict and shows clear signs of having cut short the allosaur's life. Continue reading ...

Getting the salt out: Electrodialysis can provide cost-effective treatment of salty water from fracked wells


October 21st, 2014         by Latest Science News -- ScienceDaily

The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that's much saltier than seawater, after leaching salts from rocks deep below the surface. Now researchers say they have found an economical solution for removing the salt from this water. Continue reading ...

Immune proteins moonlight to regulate brain-cell connections


October 21st, 2014         by Latest Science News -- ScienceDaily

When it comes to the brain, 'more is better' seems like an obvious assumption. But in the case of synapses, which are the connections between brain cells, too many or too few can both disrupt brain function. Researchers recently found an immune-system protein that moonlights in the nervous system to help regulate the number of synapses, and could play an unexpected role in conditions such as Alzheimer's disease, type 2 diabetes and autism.

Exploring x-ray phase tomography with synchrotron radiation


October 21st, 2014         by Latest Science News -- ScienceDaily

X-ray phase tomography is an imaging technique that uses penetrating X-rays to create volumetric views through "slices" or sections of soft biological tissues, such as tumors, and it offers strongly enhanced contrast compared to conventional CT scans. Yet scientists still do not know which X-ray phase tomography methods are best suited to yield optimized results for a wide variety of conditions. Continue reading ...

Not just skin cancer: Triplet threat from the sun


October 21st, 2014         by Latest Science News -- ScienceDaily

The most obvious effects of too much sun exposure are cosmetic, like wrinkled and rough skin. Some damage, however, goes deeper—ultraviolet light can damage DNA and cause proteins in the body to break down into smaller, sometimes harmful pieces that may also damage DNA, increasing the risk of skin cancer and cataracts. Understanding the specific pathways by which this degradation occurs is an important step in developing protective mechanisms against it. Continue reading ...
