Air Pollution, Climate Change Curb Food Supplies

July 29, 2014 | by MIT | News | Comments

Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution — specifically ozone pollution, which is known to damage crops. A new study shows that these interactions can be quite significant.

Vision-correcting Display Renders Glasses Obsolete

July 30, 2014 7:00 am | by UC Berkeley | Videos | Comments

Researchers are developing computer algorithms to compensate for an individual’s visual impairment, and creating vision-correcting displays that enable users to see text and images clearly without wearing eyeglasses or contact lenses.                        


Neanderthal Jaws Evolved Before Brains

July 29, 2014 3:32 pm | by Todd Shilton, Editor, The Conversation | News | Comments

Ancient remains have confirmed that the face and jaw evolved before the rest of the skull in Neanderthals and early human ancestors. Research conducted at the Sima de los Huesos (Pit of the Bones) archaeological site in northern Spain has confirmed a much-debated hypothesis on how our early human ancestors evolved.


Brain Study Reveals Social Origin of Intelligence

July 29, 2014 3:19 pm | by Univ. of Illinois at Urbana-Champaign | News | Comments

By studying the injuries and aptitudes of Vietnam War veterans who suffered penetrating head wounds during the war, scientists are tackling - and beginning to answer - longstanding questions about how the brain works. The researchers found that brain regions that contribute to optimal social functioning are also vital to general and emotional intelligence.


Mutant Protein 'Hijacks' Cell Program to Spread Cancer

July 29, 2014 3:12 pm | by Cold Spring Harbor Laboratory | News | Comments

Researchers have discovered how the protein p53-psi, a variant of the well-known anti-cancer guardian protein p53, can reprogram cells to "switch sides" and acquire pro-metastatic features.                             


Brain Marker Explains Stress Susceptibility

July 29, 2014 3:05 pm | by Duke Univ. | News | Comments

Some people can handle stressful situations better than others, and it's not all in their genes: Even identical twins show differences in how they respond. Researchers have identified a specific electrical pattern in the brains of genetically identical mice that predicts how well individual animals will fare in stressful situations.


Report Questions Physician Training Program

July 29, 2014 3:01 pm | by National Academies of Sciences | News | Comments

The U.S. should significantly reform the federal system for financing physician training and residency programs to ensure that the public’s $15 billion annual investment is producing the doctors that the nation needs, says a new report by the Institute of Medicine.


Report: Worldwide Water Shortage by 2040

July 29, 2014 2:54 pm | by Aarhus Univ. | News | Comments

Two new reports that focus on the global electricity water nexus have just been published. Three years of research show that by the year 2040 there will not be enough water in the world to quench the thirst of the world population and keep the current energy and power solutions going if we continue doing what we are doing today. It is a clash of competing necessities, between drinking water and energy demand.

Police officers were deployed to Liberia's international airport to ensure passengers are screened for Ebola symptoms as a major regional airline announced Tuesday it was suspending flights to the cities hardest hit by an outbreak that has killed more than 670 people.


Preemie Drug Maker Fights Pediatricians' New Advice

July 29, 2014 8:46 am | by Lindsey Tanner, Associated Press | News | Comments

A costly drug given mostly to premature babies is at the center of a clash between the manufacturer and the nation's leading pediatrician's group, which recommends scaling back use of the medicine. The dispute involves new guidelines from the American Academy of Pediatrics, which say medical evidence shows the drug benefits few children other than very young preemies.


Healthy Lifestyle Means Healthy Cell Aging

July 29, 2014 8:41 am | by UC San Francisco | News | Comments

A new study from UC San Francisco is the first to show that while the impact of life's stressors accumulate overtime and accelerate cellular aging, these negative effects may be reduced by maintaining a healthy diet, exercising and sleeping well.


A Genome to Feed the World

July 29, 2014 8:36 am | by Univ. of Arizona | News | Comments

An international team of researchers has sequenced the complete genome of African rice. The genetic information will enhance scientists' and agriculturalists' understanding of the growing patterns of African rice, as well as enable the development of new rice varieties that are better able to cope with increasing environmental stressors to help solve global hunger challenges.


Google Searches Hold Key to Future Market Crashes

July 29, 2014 7:00 am | by Univ. of Warwick | News | Comments

A team of researchers has developed a method to automatically identify topics that people search for on Google before subsequent stock market falls. The researchers suggest that this method could be applied to help identify warning signs in search data before a range of real-world events.


Common Mineral Can Make, Break Bonds

July 29, 2014 7:00 am | by Arizona State Univ. | News | Comments

Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth's deep carbon cycle: they provide energy for the deep biosphere and may have implications for the origins of life. However, very little is known about how minerals influence organic reactions. A team of researchers has demonstrated how a common mineral acts as a catalyst for specific hydrothermal organic reactions.


What's Old is New Again: 3-D Printing of Antique Instruments

July 29, 2014 7:00 am | by Pat Eaton-Robb, Associated Press | News | Comments

Researchers are using medical technology to breathe new life into some antique musical instruments. They have developed a process for using CT scanning technology not only to make images of those instruments but also to print 3-D copies of parts that will allow more of them to be played.
