Falcon 9 aborts launch attempt

A SpaceX Falcon 9 aborted its launch May 19 moments after its engines ignited when computers detected higher pressure readings than allowed. The center engine pressure built above limits and a shutdown occurred one-half second before liftoff, SpaceX officials said.

Oxytocin improves brain function in children with autism

Preliminary results from an ongoing, large-scale study shows that oxytocin -- a naturally occurring substance produced in the brain and throughout the body -- increased brain function in regions that are known to process social information in children and adolescents with autism spectrum disorders (ASD).

Pollution teams with thunderclouds to warm atmosphere

New simulation study shows that atmosphere warms when pollution intensifies storms. How much the warming effect of these clouds offsets the cooling that other clouds provide is not yet clear.

Newfound exoplanet may turn to dust: Planet’s dust cloud may explain strange patterns of light from its star

Researchers have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris -- much like the tail of a comet -- is following the planet, and that this tail may tell the story of the planet's disintegration. According to the team's calculations, the tiny exoplanet, not much larger than Mercury, will completely disintegrate within 100 million years.

'Rare' genetic variants are surprisingly common, life scientists report

A large survey of human genetic variation shows that rare genetic variants are not so rare after all, and offers insights into human diseases. A team of scientists studied 202 genes in 14,002 people -- one of the largest ever in a sequencing study in humans.

A crowning success for crayfish

Australian freshwater crayfish have a tooth enamel very similar to humans. Nature sometimes copies its own particularly successful developments. Scientists have now found that the teeth of the Australian freshwater crayfish Cherax quadricarinatus are covered with an enamel amazingly similar to that of vertebrates. Both materials consist of calcium phosphate and are also very alike in terms of their microstructure. This extremely hard substance has apparently developed in freshwater crayfish independently from vertebrates, as it makes the teeth particularly strong.

New method detects traces of veterinary drugs in baby food

The quantities are very small, but in milk powder and in meat-based baby food, residues of drugs given to livestock were found. Researchers have now developed a system to analyze these substances quickly and precisely. Antibiotics, such as tilmicosine, or antiparasitic drugs, such as levamisole, are given to livestock in order to avoid illness, but they can remain later in food.
