Infants React to Social Cues from Sclera

October 28, 2014 2:00 pm | by Univ. of Virginia | News | Comments

Humans are the only primates with large, highly visible sclera– the white part of the eye. The eye plays a significant role in the expressiveness of a face, and how much sclera is shown can indicate the emotions or behavioral attitudes of a person. A new study has found that the ability to respond to eye cues apparently develops during infancy– at around seven months.

Two M Barrels of Oil Rest on Seafloor

October 28, 2014 7:00 am | by UC Santa Barbara | News | Comments

Because of the environmental disaster’s unprecedented scope, assessing the damage caused by the 2010 Deepwater Horizon spill in the Gulf of Mexico has been a challenge. One unsolved puzzle is the location of two million barrels of submerged oil thought to be trapped in the deep ocean.

Cell Membranes Spontaneously Assemble

October 28, 2014 7:00 am | by UC San Diego | News | Comments

All living cells use membranes to define physical boundaries and control the movement of biomolecules. Now, researchers have found a self-driven reaction can assemble phospholipid membranes, like those that enclose cells.

Test Needs One Drop of Blood to Check Vitamin B12

October 28, 2014 7:00 am | by Univ. of British Columbia | News | Comments

Researchers have developed a novel method to test for vitamin B12 deficiency that is sensitive enough to work on anyone, including newborn babies and large swaths of the general population.

Lower Population Won't Be 'Quick Fix' for Nature

October 28, 2014 7:00 am | by Univ. of Adelaide | News | Comments

New multi-scenario modeling of world human population has concluded that even stringent fertility restrictions or a catastrophic mass mortality would not bring about large enough change this century to solve issues of global sustainability.

Immune System Gene Key to Slowing Biological Clock

October 28, 2014 7:00 am | by American Friends of Tel Aviv Univ. | News | Comments

Difficulty in conceiving a child is a major challenge for one in seven heterosexual couples in America, especially for those over the age of 35. Now, a study has found that neutralizing an immune system gene could improve the success of fertility treatments in women.

Ultrasounds Help Kids with Speech Impediments

October 28, 2014 7:00 am | by New York Univ. | News | Comments

Using ultrasound technology to visualize the tongue’s shape and movement can help children with difficulty pronouncing “r” sounds, according to a small study. The ultrasound intervention was effective when individuals were allowed to make different shapes with their tongue in order to produce the “r” sound, rather than being instructed to make a specific shape.

Image of the Week: Shipwreck Found Near Aeolian Islands

October 28, 2014 7:00 am | by Associated Press, Jason Dearen | News | Comments

Highly trained technical divers with a Florida-based group are helping Italian researchers to unlock an ancient shipwreck thought to date to the second Punic Wars between Rome and Carthage. Able to descend hundreds of feet further than most divers, they aide the archaeologists by swimming about the wreck fetching artifacts— as no robotic submersible can.

Researchers Learn How Cells Sense, Respond to Chemicals

October 28, 2014 7:00 am | by Johns Hopkins Medicine | Videos | Comments

Amoebas aren’t the only cells that crawl: movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies, researchers have answered long-standing questions about how complex cells sense the chemical trails that show them where to go— and the role of cells’ internal “skeleton” in responding to those cues.

Imaging Helps Catalog Fundamental Processes of Life

October 27, 2014 2:00 pm | by Univ. of Cambridge | News | Comments

Scientists combined high-resolution 3-D confocal microscopy and computer-automated analysis of the images to survey the fission yeast genome with respect to three key cellular processes simultaneously: cell shape, microtubule organization and cell cycle progression.

Newer Blood Lowers Surgery Complications

October 27, 2014 2:00 pm | by Heart and Stroke Foundation of Canada | News | Comments

Heart surgery patients who received newly donated blood have significantly fewer post-operative complications than those who received blood that had been donated more than two weeks before their surgery, according to a study that examined a hospital’s records of non-emergency heart surgeries performed over almost nine years.

Just 30 Minutes of Exercise Helps the Brain

October 27, 2014 2:00 pm | by Univ. of Adelaide | News | Comments

Neuroscientists have discovered that just one session of aerobic exercise is enough to spark positive changes in the brain that could lead to improved memory and coordination of motor skills. They found changes in the brain that were likely to make it more "plastic" after only 30 minutes of vigorous exercise.

Faster Switching Key to Ferroelectrics

October 27, 2014 2:00 pm | by UC Berkeley | News | Comments

Ferroelectric materials– commonly used in transit cards, gas grill igniters, video game memory and more– could become strong candidates for use in next-generation computers. Researchers have found an easy way to improve the performance of ferroelectric materials in a way that makes them viable for low-power computing and electronics.
