Thanks to new technology developed in part at the UA, astronomers can now view objects in the sky at unprecedented sharpness in visible light. Using a telescope mirror that vibrates a thousand times each second to counteract atmospheric flickering, the team has achieved image resolution...

New Ohio University research suggests that the rise of an early phase of the Appalachian Mountains and cooling oceans allowed invasive species to upset the North American ecosystem 450 million years ago. Fuente : http://www.eurekalert.org/pub_releases/2013-08/ou-...

New research suggests that chronic traumatic encephalopathy, a brain disease associated with repeat brain trauma including concussions in athletes, may affect people in two major ways: Initially affecting behavior or mood or initially affecting memory and thinking abilities. Fuente :...

On Aug. 21, 2013 at 1:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of particles into space and reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but...

On Aug. 11, Fermi entered an extended phase of its mission -- a deeper study of the high-energy cosmos. This is a significant step toward the science team's planned goal of a decade of observations, ending in 2018. Fuente : http://www.eurekalert.org/pub_releases/2013-08/nsf...

While the 138,000-acre Silver Fire still smoldered, forest restoration specialists were on the job. They analyzed maps created using Landsat satellite data to determine where the burn destroyed vegetation and exposed soil -- and where to focus emergency restoration efforts. Fuente :...

A simple mixture of organic waste, such as chicken manure, and zeolite, a porous volcanic rock, has been developed into a powerful fertilizer which can also reclaim desert or contaminated land. Fuente : http://www.eurekalert.org/pub_releases/2013-08/uoc...

The concept behind gene therapy is simple: Deliver a healthy gene to compensate for one that is mutated. New research suggests this approach may eventually be a feasible option to treat Rett Syndrome, the most disabling of the autism spectrum disorders. Fuente :...

Cycads been around since before the age of the dinosaurs. Cycads living today have large, heavy seeds that suggests they rely on large fruit-eating animals to disperse their seeds. Yet there is little evidence that they are eaten and dispersed by today's larger-bodied animals, such as elephants. If...

Early-onset neonatal infection, defined as infection in the first 7 days of life, is associated with maternal infection and colonization, according to a systematic review and meta-analysis. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/_...

Sleep helps the brain consolidate what we've learned, but scientists have struggled to determine what goes on in the brain to make that happen for different kinds of learned tasks. In a new study, researchers pinpoint the brainwave frequencies and brain region associated with sleep-enhanced...

Light scoops provide optimal levels of daylight throughout the changing seasons and daily fluctuations in weather by capturing and strategically redirecting daylight into buildings. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/R...

A new report by biometric researchers uses data from thousands of frequent travelers enrolled in an iris recognition program to determine that no consistent change occurs in the distinguishing texture of their irises for at least a decade. These findings inform identity program administrators on...

Protein elF4E can promote cancer by activating another protein, 4A, to untangle knots in mRNA allowing gene translation to proceed. The discovery resolves a 35-year old mystery. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/3...

Researchers have devised a quantum algorithm for solving big linear systems of equations. Furthermore, they say the algorithm could be used to calculate complex measurements such as radar cross sections, an ability integral to the development of radar stealth technology, among many other...

Si una persona toma una lección de piano y se va a dormir, cuando se despierta sus dedos tocan mejor la secuencia de notas. ¿Cómo consigue el cerebro marcar esta diferencia a través del sueño? Esto es lo que ha investigado un equipo internacional de científicos que explica lo que ocurre en el...

Genetics may play a role in how people's taste receptors send signals, leading to a wide spectrum of taste preferences, according to food scientists. These varied, genetically influenced responses may mean that food and drink companies will need a range of artificial sweeteners to accommodate...
