Evolution too slow to keep up with climate change Posted: 09 Jul 2013 02:57 PM PDT Many vertebrate species would have to evolve about 10,000 times faster than they have in the past to adapt to the rapid climate change expected in the next 100 years, a new study has found.

Breakthrough study reveals biological basis for sensory processing disorders in kids Posted: 09 Jul 2013 11:35 AM PDT In a groundbreaking new study, researchers have found that children affected with sensory processing disorders have quantifiable differences in brain structure, showing a biological basis for the disease that sets it apart from other neurodevelopmental disorders.

Wildfires may contribute more to global warming than previously predicted Posted: 09 Jul 2013 09:41 AM PDT Wildfires produce a witch's brew of carbon-containing particles, as anyone downwind of a forest fire can attest. But measurements taken during the 2011 Las Conchas fire near Los Alamos National Laboratory show that the actual carbon-containing particles emitted by fires are very different than those used in current computer models, providing the potential for inaccuracy in current climate-modeling results.

5-D optical memory in glass could record the last evidence of civilization Posted: 09 Jul 2013 09:39 AM PDT Using nanostructured glass, scientists have, for the first time, experimentally demonstrated the recording and retrieval processes of five dimensional digital data by femtosecond laser writing. The storage allows unprecedented parameters including 360 TB/disc data capacity, thermal stability up to 1000 degrees C and practically unlimited lifetime.

3-D structures built out of liquid metal Posted: 09 Jul 2013 08:53 AM PDT Researchers have developed three-dimensional printing technology and techniques to create free-standing structures made of liquid metal at room temperature.

Space-time is not the same for everyone Posted: 09 Jul 2013 08:53 AM PDT Before the Big Bang, space-time as we know it did not exist. So how was it born? The process of creating normal space-time from an earlier state dominated by quantum gravity has been studied for years. Recent analyses suggest a surprising conclusion: not all elementary particles are subject to the same space-time.

Neandertals shared speech and language with modern humans, study suggests Posted: 09 Jul 2013 08:52 AM PDT Fast-accumulating data seem to indicate that our close cousins, the Neandertals, were much more similar to us than imagined even a decade ago. But did they have anything like modern speech and language? And if so, what are the implications for understanding present-day linguistic diversity? Modern language and speech can be traced back to the last common ancestor we shared with the Neandertals roughly half a million years ago, according to new research.

Ancient Egyptian leader makes surprise appearance at archaeological dig in Israel Posted: 09 Jul 2013 08:52 AM PDT As modern Egypt searches for a new leader, Israeli archaeologists have found evidence of an ancient Egyptian leader in northern Israel. At a site in Tel Hazor National Park, north of the Sea of Galilee, archeologists have unearthed part of a unique Sphinx belonging to one of the ancient pyramid-building pharaohs.

Rate of aging may be determined in the womb and linked to birthweight, study reveals Posted: 09 Jul 2013 06:48 AM PDT Scientists have found that key metabolites in blood -- chemical 'fingerprints' left behind as a result of early molecular changes before birth or in infancy -- could provide clues to a person's long-term overall health and rate of aging in later life.

Scientists image vast subglacial water system underpinning West Antarctica's Thwaites Glacier Posted: 09 Jul 2013 06:48 AM PDT In a development that will help predict sea level rise, scientists have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica's Thwaites Glacier, detecting a swamp-like canal system several times as large as Florida's Everglades. The new observations suggest dynamics of the subglacial water system may be as important as ocean influences in predicting the fate of Thwaites, which holds substantial potential for triggering sea-level rise.

H7N9 influenza: History of similar viruses gives cause for concern Posted: 09 Jul 2013 06:47 AM PDT The H7N9 avian flu strain that emerged in China earlier this year has subsided for now, but it would be a mistake to be reassured by this apparent lull in infections. The virus has several highly unusual traits that paint a disquieting picture of a pathogen that may yet lead to a pandemic, according to scientists.

The origin of the turtle shell: Mystery solved Posted: 09 Jul 2013 06:44 AM PDT Biologists have finally solved the riddle of the origin of the turtle shell. By observing the development of different animal species and confirming their results with fossil analysis and genomic data, researchers show that the shell on the turtle's back derives only from its ancestors' ribcage and not from a combination of internal and external bone structures as is often thought.

How nature maintains diversity: Temporal niches are important, study finds Posted: 09 Jul 2013 06:14 AM PDT By studying rapidly evolving bacteria as they diversify and compete under varying environmental conditions, researchers have shown that temporal niches are important to maintaining biodiversity in natural systems.

Irregular bed times curb young kids' brain power: And may have knock-on effects on health throughout life Posted: 08 Jul 2013 05:01 PM PDT Going to bed at different times every night throughout early childhood seems to curb children's brain power, finds a large, long term study.

Early, late first exposure to solid food appears associated with development of Type 1 diabetes Posted: 08 Jul 2013 01:19 PM PDT Both an early and late first exposure to solid food for infants appears to be associated with the development of Type 1 diabetes mellitus, according to a new study.
