Buffet dish sequences may prompt healthier choices Posted: 06 Nov 2013 05:24 PM PST Most people are unaware that food order biases what ends up on their plates: the first food in line is taken the most and biases what else is taken. This influence is so strong that in one study researchers found that two-thirds of an individual's plate is filled with the first three items they encounter, thus food order can be leveraged to encourage selection and intake of healthier foods.

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.

Lower education levels linked to unhealthy diets Posted: 06 Nov 2013 05:22 PM PST People with lower levels of education may eat larger amounts of unhealthy, calorically dense food than those with a higher education level, possibly because they are more physically active.

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.

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.
