El telescopio espacial Herschel de la ESA ha descubierto una capa fría en la atmósfera de Alfa Centauri A, una característica de nuestro Sol detectada por primera vez en otra estrella. Este descubrimiento no sólo es importante para comprender la actividad del Sol, también... Fuente :...

While short-term weather is notoriously volatile, climate is thought to represent a kind of average weather pattern over a long period. This dichotomy provides the analytical framework for scientific thinking about atmospheric variability, including climate change. But the weather-climate dichotomy...

The idea that boys are better at math and in competitions has persisted for a long time -- primarily because of the competition format. A new study shows that competitions that extend beyond a single round result in parity between the sexes. Fuente : http://www.eurekalert.org/pub_releases/2013-02/byu...

For decades scientists around the world have attempted to regenerate primary liver cells known as hepatocytes because of their numerous biomedical applications, including hepatitis research, drug metabolism and toxicity studies, as well as transplantation for cirrhosis and other chronic liver conditions. But no lab in the...

A healthy lung has some capacity to regenerate itself like the liver. In COPD, these reparative mechanisms fail. HDAC therapies may be useful for COPD, as well as other airway diseases. The levels of HDAC2 expression and its activity are greatly reduced in COPD patients. Decreased HDAC activity may impair the ability of the...

University of Kansas researchers have found that the infants of mothers who were given 600 milligrams of the omega-3 fatty acid DHA during pregnancy weighed more at birth and were less likely to be very low birth weight and born before 34 weeks gestation than infants of mothers who were given a placebo.

Some family physicians' offices discriminate against people of low socio-economic status, even when there is no economic incentive to do so under Canada's system of publicly funded universal health insurance, new research has shown. Fuente : http://www.eurekalert.org/pub_releases/2013-02/smh...

As of today, the Wikipedia entry for the hummingbird explains that the bird's flight generates in its wake a single trail of vortices that helps the bird hover. But after conducting experiments with hummingbirds in the lab, researchers at the University of California, Riverside propose that the hummingbird produces two trails...

A recombinant Newcastle disease virus kills all kinds of prostate cancer cells, including hormone resistant cells, but leaves normal cells unscathed, according to a paper published online ahead of print in the Journal of Virology. A treatment for prostate cancer based on this virus would avoid the...

Arizona State University researchers have found significantly higher levels of toxic metals in children with autism, compared to typical children. They hypothesize that reducing early exposure to toxic metals may help lessen symptoms of autism, though they say this hypotheses needs further examination. Fuente :...

The parasitic flatworm Schistosoma mansoni hatches in feces-tainted water, grows into a larva in the body of a snail and then burrows through human skin to take up residence in the veins. Once there, it grows into an adult, mates and, if it's female, starts laying eggs. It can remain in the body for decades. A new study...

A newly released international study reveals that the issue of climate change is not a priority for people in the United States and around the world. The surveys showed that when asked to rank priority worries, people were five times more likely to point to the economy over the environment. Climate change is seen as more of a...

New research examines the role of PKC in airway smooth muscle contraction and raises the possibility that this enzyme could be a therapeutic target for treating asthma, COPD, and other lung diseases. Fuente : http://www.eurekalert.org/pub_releases/2013-02/rup...

Tropical Cyclone Rusty formed on Feb. 24 and has already caused warnings up for the residents of northwestern West Australia, including Port Hedland. NASA's Terra satellite saw that outer bands of this quick-forming tropical cyclone were already affecting land. Fuente : http://www.eurekalert.org/pub_releases/2013-02/nsf...

Ex-cyclone Haruna is expected to dissipate in the Southern Indian Ocean under increasing wind shear in the next day or two. Infrared imagery from a NASA satellite shows that Haruna is being blown apart several hundred miles away from La Reunion Island. Fuente : http://www.eurekalert.org/pub_releases/2013-02/nsf...

The eighteenth tropical cyclone of the Southern Indian Ocean season formed over the weekend of Feb. 23-24 along with Cyclone Rusty as Cyclone Haruna crossed southern Madagascar. NASA's Aqua satellite measured Tropical Storm 18S' cloud top temperatures and saw powerful thunderstorms around the storm's core. Fuente :...

A new nine-year study of more than 367,000 children in Detroit supports the idea that a mysterious seasonal fluctuation in blood lead levels -- observed in urban areas throughout the United States and elsewhere in the northern hemisphere -- results from resuspended dust contaminated with lead....

Low-birth-weight babies with a particular brain abnormality are at greater risk for autism, according to a new study that could provide doctors a signpost for early detection of the still poorly understood disorder. Fuente : http://www.eurekalert.org/pub_releases/2013-02/msu...

Princeton University researchers developed a model that can help determine the future range of nearly any disease-causing parasite under climate change, even if little is known about the organism. Their method calculates how the projected temperature change for an area would alter the creature's...

Screening for lung cancer with low-dose computed tomography (LDCT) in all screening-eligible current and former smokers has the potential to avert approximately 12,000 lung cancer deaths each year in the United States. That is the conclusion of a new analysis published early online in CANCER, a peer-reviewed journal of the...

A survey of tanning salon operators in Missouri shows that 65 percent would allow children as young as 10 to 12 years old to use tanning beds. That's despite evidence that any tanning bed use increases the risk of all skin cancers, including melanoma, the deadliest form of skin cancer, later in life. Fuente :...

New research from the Children of the 90s study at the University of Bristol shows that most babies who are slow to put on weight in the first nine months of life have caught up to within the normal range by the age of 13, but remain lighter and shorter than many of their peers. There are significant differences in the pattern...
