A team of researchers led by Santos Alonso, et. al., have examined the evolutionary selective pressure for a fair skin gene, MC1R, among a large population of Spaniards in comparison to their Northern Europeans counterparts as well as individuals with melanoma. Using data from the 1,000 Genomes...

As a new feature to science reporters, the journal Molecular Biology and Evolution will be highlighting recent research publications. Highlighted in this release is research about cell growth in yeast and genetic adaptation to high-altitude conditions in Sherpas. Fuente :...

Investigadores estadounidenses han demostrado tras un estudio llevado a cabo con 35 personas que comer sano, hacer ejercicio físico moderado, relajarse y relacionarse adecuadamente, aumenta el tamaño de los telómeros. La longitud de estos complejos de ADN se vincula con el envejecimiento celular y...

Philosophers and scientists have long puzzled over where human imagination comes from. In other words, what makes humans able to create art, invent tools, think scientifically and perform other incredibly diverse behaviors? The answer, researchers conclude, lies in a widespread neural network --...

Scientists have solved a 300-year-old riddle about which direction the center of Earth spins. Earth's inner core, made up of solid iron, 'superrotates' in an eastward direction -- meaning it spins faster than the rest of the planet -- while the outer core, comprising mainly molten iron, spins...

For the first time, researchers have built and demonstrated the ability of two-dimensional disordered photonic band gap material, designed to be a platform to control light in unprecedented ways. The new material could lead to arbitrarily shaped, wavy, curved, and sharply bending ways to steer...

Un estudio realizado por investigadores británicos señala que si el ganado vacuno se sometiera a un proceso de vacunación para la Escherichia coli se evitaría el 85% de las infecciones en los seres humanos. La E. coli es una bacteria que provoca graves enfermedades gastrointestinales. Fuente :...

The PDK1 gene, known to regulate many cell functions such as metabolism and survival, is now identified as a key regulator in melanoma development and metastasis, offering new opportunities to interfere with cancer progression. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/U...

If aboriginal women had the same income and education levels as non-aboriginal women, their risk of being abused by a partner could drop by 40 percent, according to a new study. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/A...

Scientists have found a way to make dramatic improvements to the cancer cell-killing power of vinblastine, one of the most successful chemotherapy drugs of the past few decades. The team's modified versions of vinblastine showed 10 to 200 times greater potency than the clinical drug. Fuente :...

The U.S. recession that began in December 2007 may have officially ended in June 2009, but in terms of job status, pay and retirement options, American workers are feeling its lingering negative impact, according to a new study. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/b...

Researchers have previously shown that men with wider faces are more aggressive, less trustworthy and more prone to engaging in deception. Now they have shown, in a series of four studies, that individuals behave more selfishly when interacting with men with wider faces and this selfish behavior...

Spare a thought for American doctors and their partners: because of long working hours and dedication to their work, they seem to have more squabbles over home and family responsibilities than people in most other professions.. This constant struggle to balance work and home life are felt...

In a ground-breaking study, Swedish scientists have shown that people can detect nano-scale wrinkles while running their fingers upon a seemingly smooth surface. The findings could lead such advances as touch screens for the visually impaired and other products, says one of the researchers from KTH...

A research team from Bielefeld University analysed how the body language of the potential customer helps the bartenders to identify who would like to place an order and who does not. The team found that real-life observations were at odds with the widespread belief that customers wave for...

The stage is now set for superconductivity to branch out and meet some of the biggest challenges facing humanity today. A new article explains how superconducting technologies can move out of laboratories and hospitals and address wider issues such as water purification, earthquake monitoring and...

La estratosfera es donde reside la mayor parte del ozono que protege a la Tierra de los rayos ultravioleta del Sol. Por esta razón, el ozono estratosférico es a menudo llamado "bueno", a diferencia del ozono que se halla a nivel del suelo, que es llamado "malo." El ozono es un gas muy reactivo......
