Tempe, Ariz., (Jan. 21, 2016) - Mothers are deeply invested in the well being of their children, so when children go through trying times so do their moms, according to a new study by Arizona State University researchers Suniya Luthar and Lucia Cicolla.

Life on other planets would likely be brief and become extinct very quickly, say astrobiologists from The Australian National University (ANU).

In research aiming to understand how life might develop, the scientists realised new life would commonly die out due to runaway heating or cooling on their fledgling planets.

"The universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens," said Dr Aditya Chopra from the ANU Research School of Earth Sciences and lead author on the paper, which is published in Astrobiology.

College students whose parents lay on the guilt or try to manipulate them may translate feelings of stress into similar mean behavior with their own friends, a new study by a University of Vermont psychologist has found.

Those students' physical response to stress influences the way they will carry out that hostility - either immediately and impulsively or in a cold, calculated way, concluded Jamie Abaied, a UVM assistant professor of psychological science.

CAMBRIDGE, MA - A new brain imaging study from MIT and Harvard Medical School may lead to a screen that could identify children at high risk of developing depression later in life.

In the study, the researchers found distinctive brain differences in children known to be at high risk because of family history of depression. The finding suggests that this type of scan could be used to identify children whose risk was previously unknown, allowing them to undergo treatment before developing depression, says John Gabrieli, the Grover M. Hermann Professor in Health Sciences and Technology and a professor of brain and cognitive sciences at MIT.

How much alcohol you drink and how hard it affects you are rooted in your DNA, specifically, a “lazy” variant of the Alcohol Dehydrogenase 1B (ADH1B) gene, known to regulate the activity of a key group of enzymes.

When we drink, the alcohol rushes into our bloodstream, where the alcohol dehydrogenase enzymes metabolize, or break down, the ethanol into acetaldehyde. If this happens quickly, lots of acetaldehyde accumulates in a short amount of time, which can lead to adverse effects such as flushing, nausea, and headaches. Conversely, if the ethanol is metabolized slowly, the alcohol remains intact in the blood for longer periods, prolonging its more pleasant, euphoric effects.

Reduced meat consumption might not lower greenhouse gas emissions from one of the world’s biggest beef producing regions, new research has found.

The finding may seem incongruous, as intensive agriculture is responsible for such a large proportion of global greenhouse gas emissions.

According to research by University of Edinburgh, Scotland’s Rural College (SRUC) and Brazilian Agricultural Research Corporation (Embrapa), reducing beef production in the Brazilian Cerrado could actually increase global greenhouse gas emissions. The findings were published this week in the journal Nature Climate Change.
