Researchers Find Epigenetic Tie to Neuropsychiatric Disorders

July 21, 2014 2:44 pm | by Univ. of California, Irvine | News | Comments

Dysfunction in dopamine signaling profoundly changes the activity level of about 2,000 genes in the brain’s prefrontal cortex and may be an underlying cause of certain complex neuropsychiatric disorders, such as schizophrenia, according to new research.

Found: Exoplanet with Longest Known Year

July 21, 2014 2:38 pm | by Harvard-Smithsonian Center for Astrophysics | News | Comments

Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus exoplanets discovered to date are much closer to their stars and have much shorter orbital periods.

Scientists Can ID 'Worst' HIV Particles

July 21, 2014 2:35 pm | by Univ. of Michigan | News | Comments

HIV-infected people carry many different HIV viruses and all have distinct personalities—some much more vengeful and infectious than others. Yet, despite the breadth of infectivity, roughly 76 percent of HIV infections arise from a single virus. Now, scientists believe they can identify the culprit with very specific measurements of the quantities of a key protein in the HIV virus.

Parents Rank Their Obese Children as 'Very Healthy'

July 21, 2014 2:25 pm | by Univ. of California, San Diego | News | Comments

A new study suggests parents of obese children often do not recognize the potentially serious health consequences of childhood weight gain or the importance of daily physical activity in helping their child reach a healthy weight.

Ousted Pot Researcher Blames Legislators

July 21, 2014 2:17 pm | by Associated Press, Astrid Galvan | News | Comments

Veterans, medical marijuana activists and scientists welcomed the first federally approved research into pot as a treatment for post-traumatic stress disorder. But their hopes for the research were dashed when the Univ. of Arizona fired researcher Suzanne Sisley, who undertook the study after clearing four years of bureaucratic hurdles.

Research Explains Mystery of Starling Flocks

July 21, 2014 7:00 am | by Univ. of Warwick | News | Comments

The mystery behind the movements of flocking starlings could be explained by the areas of light and dark created as they fly. Research found that flocking starlings aim to maintain an optimum density at which they can gather data on their surroundings. This occurs when they can see light through the flock at many angles, a state known as marginal opacity.

'Frankenfood' Fears Sour Free Trade Agreement

July 21, 2014 7:00 am | by Associated Press, Juergen Baetz | News | Comments

Visions of chlorine-drenched chickens and the prospect of genetically modified "Frankenfood" invading dinner tables across the European Union are proving serious impediments to the signing of a sweeping free trade agreement between the U.S. and the 28-country bloc.

Method Rapidly Reconstructs Animal’s Development

July 21, 2014 7:00 am | by Howard Hughes Medical Institute | News | Comments

New imaging technology is transforming how scientists see the cellular universe, showing the form and movement of once grainy and blurred structures in stunning detail. Researchers have developed a computational method that can rapidly track 3-D movements of cells in these images. This allows them to essentially automate much of the time-consuming process of reconstructing an animal's developmental building plan cell by cell.

Research Finally Explains Bend in Appalachian Mountains

July 21, 2014 7:00 am | by Univ. of Rochester | News | Comments

The 1,500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland— except for a curious bend. Now, researchers have found that a dense block of volcanic rock forces the mountains to bend to the east through Pennsylvania, New Jersey and New York.

Process Helps Fruit Flies Cope with the Cold

July 21, 2014 12:00 am | by Univ. of Rochester | News | Comments

In colder temperatures, some biological processes in the cells of clod-blooded animals are slowed down more than others, which should throw the delicate chemical balance out of whack. Yet, those cells manage to keep their biological processes coordinated. Now, researchers have found out how they do that.

Researcher Calls For ‘Risky Research’ Review System

July 18, 2014 12:00 pm | by The Conversation, Nicholas Evans | News | Comments

The danger of reporting findings before peer review is that scientists often can’t talk about the details of their research, which can lead to hype or fear in the media.
