Breastfeeding possible deterrent to autism Posted: 06 Nov 2013 05:24 PM PST The emergence of autism in young children appears to result from dysmyelination of brain neurons, related to inadequate supply of insulin-like growth factor (IGF) in the newborn. The deficiency of IGF in affected infants may be due to a combination of genetic and environmental factors yet to be determined. If this hypothesis is correct, breastfeeding in particular could increase IGF levels, thereby compensating for an inborn deficiency of the growth factor.

Earliest record of copulating insects discovered Posted: 06 Nov 2013 05:24 PM PST Scientists have found the oldest fossil depicting copulating insects in northeastern China.

Presence of human settlements has negative impact on tiger connectivity Posted: 06 Nov 2013 05:22 PM PST Human settlements and roads place greater barriers on tiger dispersal than distance.

Clear association between ACE inhibitors, acute kidney injury Posted: 06 Nov 2013 05:22 PM PST New research shows clear association between ACE inhibitors -- drugs used to treat high blood pressure and heart disease -- and acute kidney injury. These and similar drugs are the second most prescribed on the National Health Services in England.

Stress makes snails forgetful Posted: 06 Nov 2013 05:22 PM PST New research on pond snails has revealed that high levels of stress can block memory processes. Researchers trained snails and found that when they were exposed to multiple stressful events they were unable remember what they had learned.

Children who have autism far more likely to have tummy troubles Posted: 06 Nov 2013 05:22 PM PST Children with autism experience gastrointestinal upsets such as constipation, diarrhea and sensitivity to foods six-to-eight times more often than do children who are developing typically, and those symptoms are related to behavioral problems, including social withdrawal, irritability and repetitive behaviors.

Infected butterflies lead geneticists up the garden path Posted: 06 Nov 2013 05:19 PM PST For animal species that cannot be distinguished using their external characteristics, genetic techniques such as DNA barcoding can help to identify cryptic species. An international team of researchers has now demonstrated how a bacterial infection can mimic cryptic speciation in butterflies. To avoid false results in the future, scientists recommend more in-depth genetic studies.

Floods didn't provide nitrogen 'fix' for earliest crops in frigid north Posted: 06 Nov 2013 05:18 PM PST Floods didn't make floodplains fertile during the dawn of human agriculture in the Earth's far north because the waters were virtually devoid of nitrogen. Instead, the hardy Norsemen and early inhabitants of Russia and Canada can thank cyanobacteria in the floodplains themselves for the abundant grasses that fed game and cattle, a process that continues today.

Russian fireball yields scientific treasure trove: Researchers obtain crucial data from meteoroid impact Posted: 06 Nov 2013 01:41 PM PST A team of NASA and international scientists for the first time have gathered a detailed understanding of the effects on Earth from a small asteroid impact. The unprecedented data obtained as the result of the airburst of a meteoroid over the Russian city of Chelyabinsk on Feb. 15, 2013, has revolutionized scientists' understanding of this natural phenomenon.

Rare new microbe found in two spacecraft clean rooms Posted: 06 Nov 2013 01:26 PM PST A rare, recently discovered microbe that survives on very little to eat has been found in two places on Earth: spacecraft clean rooms in Florida and South America. Microbiologists often do thorough surveys of bacteria and other microbes in spacecraft clean rooms. Fewer microbes live there than in almost any other environment on Earth, but the surveys are important for knowing what might hitch a ride into space. If extraterrestrial life is ever found, it would be readily checked against the census of a few hundred types of microbes detected in spacecraft clean rooms.

Speaking a second language may delay different dementias Posted: 06 Nov 2013 01:25 PM PST In the largest study on the topic to date, research shows that speaking a second language may delay the onset of three types of dementias.

Addicts may be seeking relief from emotional lows more than euphoric highs Posted: 06 Nov 2013 12:24 PM PST Researchers are challenging the commonly held view that drug addiction occurs because users are always going after the high. Based on new animal studies, they say the initial positive feelings of intoxication are short lived -- quickly replaced by negative emotional responses which may be more important in understanding substance abuse.

From one collapsing star, two black holes form and fuse Posted: 06 Nov 2013 12:24 PM PST Over billions of years, small black holes can slowly grow into supermassive black holes by taking on mass from their surroundings, and also by merging with other black holes. But this slow process can't explain how supermassive black holes existing in the early universe would have formed less than one billion years after the Big Bang. New findings help to test a model that solves this problem.

Bringing sun's light and energy to interior rooms: Innovative solar technology may lead to interior lighting revolution Posted: 06 Nov 2013 12:24 PM PST Researchers have seen the light -- a bright, powerful light -- and it just might change the future of how building interiors are brightened. In fact, that light comes directly from the sun. And with the help of tiny, electrofluidic cells and a series of open-air "ducts," sunlight can naturally illuminate windowless work spaces deep inside office buildings and excess energy can be harnessed, stored and directed to other applications.

Threats to cloud data storage, mobile devices Posted: 06 Nov 2013 12:22 PM PST As more businesses find their way into the cloud, few engage in security measures beyond those provided by the associated cloud storage firm, a new report notes. Even fewer seek heightened data protection because of concerns that usability and access to remote data would be significantly reduced.

RNA controls splicing during gene expression, further evidence of 'RNA world' origin in modern life Posted: 06 Nov 2013 10:19 AM PST RNA is the key functional component of spliceosomes, molecular machines that control how genes are expressed, report scientists. The discovery establishes that RNA, not protein, is responsible for catalyzing this fundamental biological process and enriches the hypothesis that life on Earth began in a world based solely on RNA.

New explanation for infection susceptibility in newborns: It is all about helping beneficial bacteria colonize the gut Posted: 06 Nov 2013 10:19 AM PST Cells that allow helpful bacteria to safely colonize the intestines of newborn infants also suppress their immune systems to make them more vulnerable to infections, according to new research. The study could prompt a major shift in how medicine views the threat of neonatal infections -- and how researchers go about looking for new strategies to stop it, said scientists who conducted the study.

Discovery of HIV 'invisibility cloak' reveals new treatment opportunities Posted: 06 Nov 2013 10:19 AM PST Scientists have discovered a molecular invisibility cloak that enables HIV, the virus that causes AIDS, to hide inside cells of the body without triggering the body's natural defense systems.

Sports Decision Review System: Hawk-eye or human eye? Posted: 06 Nov 2013 04:37 AM PST For ardent sports fans, decision review technology – popularly known as Hawk-Eye – is having a 'marmite moment'. It's either welcomed as a definitive mechanism to assist a referee make the right decision or an imperfect tool which has done nothing to improve the enjoyment of sporting fixtures.  Now used in a wide range of games including football, tennis, hurling and Gaelic football, it has often proved controversial.

Astronomers establish the strength of high-inclination asteroids Posted: 06 Nov 2013 04:35 AM PST Astronomers have been observing faint asteroids with highly inclined orbits. They found that a smaller fraction of tiny bodies occur among high-inclination asteroids than those near the ecliptic plane. This means that large asteroids in high-velocity collisions between asteroids probably have a greater increase of strength in resisting disruption than those in the present mean-velocity collisions. Clarification of the relationship between collisional velocity and asteroids' disruptive strength is helpful in understanding the collisional evolution of asteroids in the early Solar System.
