With the aid of a straightforward experiment, researchers have provided some clues to one of biology's most complex questions: how ancient organic molecules came together to form the basis of life.…

Have you ever wondered why it seems like the littlest things make people angry?   University of Minnesota marketing professor Vladas Griskevicius says he can explain in three words why people…

A key challenge of nanotechnology research is investigating how different materials behave at lengths of merely one-billionth of a meter. When shrunk to such tiny sizes, many everyday materials…

Bling, foreclosures, rising credit card debt, bank and auto bailouts, upside down mortgages and perhaps a mid-life crisis new Corvette---all symptoms of compulsive overspending.   University of…

In the rainforests of equatorial Asia, a link between drought and deforestation is fueling global warming, finds an international study that includes a UC Irvine scientist. The study, analyzing six…

When it comes to the world of the very, very small — nanotechnology — we may have a big problem: Nano and its capacity to alter the fundamentals of nature could be failing the moral litmus test of…

Scientists from Monash University, Melbourne have shown that infants born prematurely have lower blood pressure during sleep in the first six months of life, compared to healthy, full-term infants.…

In the search for life beyond Earth, scientists 'follow the water' to find places that might be hospitable. However, every home gardener knows that plants need more than water, or even sunshine. They…

It's always fun science when we can say researchers from Brown have discovered that men have more red in their skin and women more green - but Michael J. Tarr and graduate student Adrian Nestor say…

Cells are filled with membrane-bound organelles like the nucleus, mitochondria and endoplasmic reticula. Over the years, scientists have made much progress in understanding the biomolecular details…

Eating saturated fats from butter, cream and meat, as well as trans fats found in hydrogenated oils can boost our risk of cardiovascular disease, while consuming mono-unsaturated fat can be good for…

New data from The Kinsey Institute at Indiana University demonstrate that many women think condoms undermine sexual pleasure, but those who use both hormonal contraception and condoms report higher…

Having kids believe there's a jolly man in a red suit who visits on Christmas Eve doesn't turn out to be very detrimental, according to a new analysis by Serge Larivée, although some parents can feel…

Every living thing is composed of cells and, via receptor proteins on their outer surface, cells communicate with each other and with the outside world. Receptors are found on skin cells (pain and…

A new genome-wide study examines genetic variants associated with nine metabolic traits and is the first to draw out novel variants from a population unselected for current disease. The traits are…

A new study presages a real aim of genetics: to look at whole populations to in order determine the significance of individual genetic variants for individual health. A research team says they found…

(Publicado no jornal O Primeiro de Janeiro a 29/11/2007)O actual governo “devia governar um bocadinho mais à esquerda”, afirmou Mário Soares. Respondeu Vitalino Canas: "O PS governa à esquerda e…

The debate over gene selection versus group or multi-level selection continues unabated in biological circles, and no end appears in sight. Despite a resurgence of interest in group selection, the…

A future episode of CSI or your favorite crime drama may have an interesting new way to establish time of death, thanks to the work of a team of researchers from the University of Santiago de…

The wild pea pod is big and heavy, with seemingly little prayer of escaping the shade of its parent plant. And yet, like a grounded teenager who knows where the car keys are hidden, it manages – if…
