Scientists outline long-term sea-level rise in response to warming of planet - 15/07/2013

A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms. This is one of the first analyses to combine four major contributors to potential sea level rise into a collective...

Notre Dame researchers offer new insights on cancer cell signaling - 15/07/2013

A pair of studies by a team of University of Notre Dame researchers led by Crislyn D'Souza-Schorey, professor of biological sciences, sheds light on a biological process which is activated across a vast range of malignancies. Fuente : http://www.eurekalert.org/pub_releases/2013-07/uon...

The heart of space weather observed in action - 15/07/2013

Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions...

Pain control in children with cerebral palsy - 15/07/2013

Researchers at Holland Bloorview Kids Rehabilitation Hospital have found that more than 25 percent of children with cerebral palsy seen by physicians have moderate to severe chronic pain, limiting their activity. Findings indicate that pediatricians should be aware of chronic pain in this group and...

Affordable Care Act could cause people to leave their jobs - 15/07/2013

As a consequence of the Affordable Care Act, between 500,000 and 900,000 Americans may choose to stop working. That possibility is predicted in a new analysis of an analogous situation in reverse: the abrupt end of Tennessee's Medicaid expansion in 2005. That year, Tennessee dropped 170,000 of its citizens from Medicaid. It was...

Early spatial reasoning predicts later creativity and innovation, especially in STEM fields - 15/07/2013

Exceptional spatial ability at age 13 predicts creative and scholarly achievements over 30 years later, according to results from a new longitudinal study published in Psychological Science, a journal of the Association for Psychological Science. Fuente :...

Antiviral enzyme contributes to several forms of cancer - 14/07/2013

Researchers have discovered that a human antiviral enzyme causes DNA mutations that lead to several forms of cancer. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/h...

Scientists solve a 14,000-year-old ocean mystery - 14/07/2013

At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large...

Artificial cells to study molecular crowding and gene expression created - 14/07/2013

Scientists have approximated molecular crowding in an artificial cellular system and found that tight quarters help the process of gene expression, especially when other conditions are less than ideal. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/Q...

Boldly illuminating biology's 'dark matter' - 14/07/2013

Microbial dark matter comprises the invisible infrastructure of life that can have profound influences on the most significant environmental processes. By employing next generation DNA sequencing of single cell genomes, researchers are systematically filling in the bacterial and archaeal tree of...

Continuous satellite monitoring of ice sheets needed to better predict sea-level rise - 14/07/2013

The length of the satellite record for the Greenland and Antarctic ice sheets is currently too short to tell if the recently reported speed-up of ice loss will be sustained in the future or if it results from natural processes, according to a new study. Fuente :...

Is the ice in Greenland in growing decline? Accelerated loss of ice mass could be 'ice shield weather' - 14/07/2013

The time period of satellite observations of the ice sheets of Greenland and the Antarctic is still too short to be able to say whether the accelerated loss of ice measured today will persist in the future. Researchers conclude that predictions of the contribution of both ice shields to the sea...

Key step in molecular 'dance' that duplicates DNA deciphered - 14/07/2013

Scientists have captured new details of the biochemical interactions necessary for cell division. The research may suggest ways for stopping cell division when it goes awry. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/O...

Descubiertas nuevas causas de terremotos inducidos por la actividad industrial - 14/07/2013

La inyección de aguas residuales bajo tierra aumenta la probabilidad de que se produzcan terremotos, ya que incrementa el estrés sísmico de la zona. Estas conclusiones se desprenden de dos estudios publicados en Science sobre la implicación de las actividades humanas en la generación de... Fuente :...

Se investiga el impacto perjudicial de los protectores solares sobre los ecosistemas marinos costeros - 14/07/2013

Una investigación del Instituto Mediterráneo de Estudios Avanzados (IMEDEA, CSIC-UIB), en España, estudia el impacto potencial que los protectores solares usados por los bañistas tienen sobre los ecosistemas marinos costeros. El trabajo, que se ha publicado en la revista científica internacional......

Imaging electron pairing in a simple magnetic superconductor - 14/07/2013

Using a technique to measure the energy required for electrons to pair up and how that energy varies with direction, scientists have identified the factors needed for magnetically mediated superconductivity -- as well as those that aren't.

Key step in molecular 'dance' that duplicates DNA deciphered - 14/07/2013

Scientists have captured new details of the biochemical interactions necessary for cell division -- molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target. The research may suggest ways for stopping cell division when it goes awry....

Continuous satellite monitoring of ice sheets needed to better predict sea-level rise - 14/07/2013

The length of the satellite record for the Greenland and Antarctic ice sheets is currently too short to tell if the recently reported speed-up of ice loss will be sustained in the future or if it results from natural processes, according to a new study led by Dr. Bert Wouters from the University of Bristol.

Some volcanoes 'scream' at ever-higher pitches until they blow their tops - 14/07/2013

Swarms of small earthquakes often precede a volcanic eruption. They can reach such rapid succession that they create a "harmonic tremor" that resembles sound made by some musical instruments. A new analysis of an eruption sequence at Alaska's Redoubt Volcano in March 2009 shows the harmonic tremor glided to substantially higher...

Antiviral enzyme contributes to several forms of cancer, University of Minnesota researchers say - 14/07/2013

Scientists discover kill-switch controls immune-suppressing cells - 14/07/2013

Scientists have uncovered the mechanism that controls whether cells that are able to suppress immune responses live or die. The discovery of the cell death processes that determine the number of 'regulatory T cells' an individual has could one day lead to better treatments for immune disorders....

Sexual reproduction only second choice for powdery mildew - 14/07/2013

Genetically, powdery mildew is perfectly adapted to its host plants. Evidently, sexual reproduction and new combinations of genetic material usually prove disadvantageous for the fungus. Asexual reproduction, however, is considerably more successful for mildew, as plant biologists from the...
