Researchers at Weill Cornell Medical College have uncovered a mechanism that guides the exquisite wiring of neural circuits in a developing brain -- gaining unprecedented insight into the faulty circuits that may lead to brain disorders ranging from autism to mental retardation. Fuente :...

Air pollution in the Northern Hemisphere in the mid-20th century cooled the upper half of the planet and pushed rain bands south, contributing to the prolonged and worsening drought in Africa's Sahel region. Clean air legislation in the 1980s reversed the trend and the drought lessened. Fuente :...

A research team led by pediatric blood and marrow transplantation experts Mark Osborn, Ph.D. and Jakub Tolar, M.D., Ph.D. from the Masonic Cancer Center, University of Minnesota, have discovered a remarkable new way to repair genetic defects in the skin cells of patients with the skin disease...

Stanford scientists have identified key acoustic characteristics of the 2011 Japan earthquake that indicated it would cause a large tsunami. The technique could be applied worldwide to create an early warning system for massive tsunamis. Fuente : http://www.eurekalert.org/pub_releases/2013-06/su-...

Dust clouds around stars are thought to hide many undiscovered planets with conditions suitable for life, but observations have been hampered by the fact that only the brightest such clouds can be detected with current technology. UA astronomers are developing a technique to detect faint dust...

Towering thunderstorms are a sign of a strong tropical cyclone, and NASA's TRMM satellite spotted thunderstorms reaching heights of almost 9 miles high within Tropical Storm Andrea. NASA's Aqua satellite provided an infrared view that revealed very cold cloud top temperatures that coincided with...

Today, two scientists from Cold Spring Harbor Laboratory publish a mathematical method of simplifying and interpreting genome data bearing evidence of mutations, such as those that characterize specific cancers. Fuente : http://www.eurekalert.org/pub_releases/2013-06/csh...

Remora fish, with a sucking disc on their heads, have been the stuff of legend. They often attach themselves to boat hulls and were once thought to purposely slow the boat down. While that is a misunderstanding, something else not well understood was the origins of the fish's sucking disc....

Through genetic engineering of laboratory models, researchers at Dartmouth-Hitchcock Norris Cotton Cancer Center have uncovered a vulnerability in the way cancer cells diverge from normal regenerating cells that may help treat children with leukemia as reported in the journal PNAS on June 3, 2013....

Researchers found that a type of predatory sea slug with a simple nervous system has more complex cognitive abilities than previously thought, allowing it to learn the warning cues of dangerous prey and avoid them in the future. Fuente : http://www.eurekalert.org/pub_releases/2013-06/uoi...

La costilla de un neandertal que vivió en Croacia aún conserva lesiones de un tipo de tumor que hoy es relativamente frecuente en humanos ||| Fuente : http://feedproxy.google.com/~r/materia/noticias/~3...

Los neandertales sufrieron tumores óseos como los que padecemos en la actualidad. Así lo confirma un estudio publicado en la revista PLOS ONE, basado en el hallazgo en Croacia de una costilla de neandertal que conservaba evidencias de una displasia fibrosa, una tumoración benigna que a veces se...

If you suspect that opening windows to let in fresh air might be good for you, a new study has confirmed your hunch. Analyzing extensive data on ventilation rates collected from more than 150 classrooms in California over two years, the researchers found that bringing classroom ventilation rates up to the state-mandated...

Physicists have discovered surprising changes in electrical resistivity in iron-based superconductors. The findings offer further evidence that magnetism and superconductivity are closely related in this class of novel superconductors. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/C...

Untreated HIV infection destroys a person's immune system by killing infection-fighting cells, but precisely when and how HIV wreaks this destruction has been a mystery until now. New research reveals how HIV triggers a signal telling an infected immune cell to die. This finding has implications for preserving the immune...

A phase 1 clinical trial for the first treatment to reset the immune system of multiple sclerosis (MS) patients showed the therapy was safe and dramatically reduced patients' immune systems' reactivity to myelin by 50 to 75 percent. The therapy used billions of patients' own specially processed blood cells to create tolerance...

Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this world. Researchers have found that icy comets that crashed into Earth millions of years ago could have produced life building organic compounds, including the building blocks of...

Surprisingly large amounts of discarded trash end up in the ocean. Plastic bags, aluminum cans, and fishing debris not only clutter our beaches, but accumulate in open-ocean areas such as the "Great Pacific Garbage Patch." Now, new research shows that trash is also accumulating in the deep sea, particularly in Monterey Canyon....

A study that was presented in Nature last year attracted a great deal of attention when it asserted that intuition promotes cooperation. But a group of researchers in behavioral and neuroeconomics say that this is not true, in a new study now being published in Nature. Fuente :...

We don't just share our lives with animals; we are animals -- a reality that we often choose to forget in modern Western culture. New research delves deeper into our relationship with other creatures, critically examining our own animal nature, and looking at how animals profoundly influence our culture -- perhaps more so than...

Most skygazers recognize the Orion Nebula, one of the closest stellar nurseries to Earth. Although it makes for great views in backyard telescopes, the Orion Nebula is far from the most prolific star-forming region in our galaxy. That distinction may go to one of the more dramatic stellar nurseries like the Cat's Paw Nebula,...
