Children who can stay focused and don't sweat the small stuff have a better shot at good health in adulthood -- especially girls, according to findings reported in the May issue of Health Psychology.

A detailed analysis of the feet of Homo floresiensis, the miniature hominins who lived on a remote island in eastern Indonesia until 18,000 years ago, may help settle a question hotly debated among paleontologists: how similar was this population to modern humans? A new research paper in Nature  may help answer this question.While the so-called "hobbits" walked on two legs, they say, several features of their feet were so primitive that their gait was not efficient.

A new study from Northwestern University shows what many mothers already know: their babies are a lot smarter than others may realize.Though only five months old, the study's cuties indicated through their curious stares that they could differentiate water in a glass from solid blue material that looked very much like water in a similar glass. The finding that infants can distinguish between solids and liquids at such an early age builds upon a growing body of research that strongly suggests that babies are not blank slates who primarily depend on others for acquiring knowledge. That's a common assumption of researchers in the not too distant past.

Most people know Edwin Hubble as a famed astronomer, the namesake of the orbiting Hubble Space Telescope (HST).  Most probably don't know he also starred as a forward on the University of Chicago Maroons' Big Ten-champion basketball teams in the early part of the 20th century.  As an astronomer, Hubble showed that galaxies besides our own existed in the universe, and that the universe is expanding. These findings formed the cornerstone of the Big Bang theory of the universe's origin and opened the field of cosmology.  As a basketball player, the 6-foot-2 Hubble was a member of Chicago teams that posted records of 24-2 in 1907-08 and 10-3 in 1908-09.

Toddlers with autism appear more likely to have an enlarged amygdala, a brain area associated with numerous functions, including the processing of faces and emotion, according to a report in the May issue of Archives of General Psychiatry.

In addition, this brain abnormality appears to be associated with the ability to share attention with others, a fundamental ability thought to predict later social and language function in children with autism.

It's certainly the case that 'dark matter', like 'Smurf' or 'government regulation', has in recent times become a de facto explanation for the unexplained.   We aren't big believers in magic so mysterious, undetected forces that explain everything probably actually explain nothing - and tossing out Newton in the process  brings on a higher order of scrutiny, since he has been declared irrelevant often before only to survive quite nicely.Dark matter is currently unable to reconcile all the current discrepancies between measurements and predictions based on theoretical models and competing theories of gravitation have therefore been developed - their problem is that they conflict with Newton's theory of gravitation.

If you want to learn a little something about 'characteristic curvature', you're in the right place.   Hydrophilic surfactants love water, but lipophilic surfactants love oils and dislike water.Okay, if you were expecting an article about Jessica Alba, you can stop reading.But if chemistry is your thing, a new research protocol developed by Dr. Acosta and colleagues from the University of Toronto's Department of Chemical Engineering and Applied Chemistry builds on more than 30 years of phase behavior studies of microemulsions, the clear, stable liquid mixtures of oil, water and surfactant, and the concept of hydrophilic-lipophilic difference.

NASA's Fermi Gamma-ray Space Telescope, launched June 2008, has certainly started its career with a (big) bang, discovering a new class of pulsars and watching flaring jets in galaxies billions of light-years away.Now it's going after another cosmic mystery; high-energy particles in cosmic rays.

The description of compounds and interactions between atoms is one of the basic objectives of chemistry. Admittedly, chemical bonding models, which describe these properties very well, already exist. However, any deviation from the normal factors may lead to improving the models further. Chemists with Professor Thomas M. Klapötke at Ludwig-Maximilians-Universität (LMU) München have now analyzed a molecule, which has an extremely short bond length.

Increased social stress in childhood and young adulthood has a direct link to later increased dating violence, and that young social stress is impacted by things like unemployment and economic worries, according to Murray Straus, professor of sociology and co-director of the University of New Hampshire Family Research Laboratory.  The research, based on a 32-nation study,  was presented at the conference on “War, Terrorism, and Social Stress: Impacts on Crime and the Criminal Justice System” at the Institute of Criminology, The Hebrew University, Jerusalem, Monday, May 4, 2009. He studied 14,252 university students from 68 universities in 32 nations in an International Dating Violence Study.

'Drought-proofing' Australia's urban regions by installing large domestic water tanks may enable the dengue mosquito Aedes aegypti to regain its foothold across the country and expand its range of possible infections, according to a new study published in PLoS Neglected Tropical Diseases. Dr Nigel Beebe and colleagues from the University of Queensland, CSIRO Entomology, the Australian Army Malaria Institute, and the Communicable Diseases Branch of Queensland Health, Brisbane, challenge the common assumption that climate change will drive the spread of this mosquito. 

An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team's results one day could be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy.
