Research Explains Beetle’s Defense Mechanism

May 4, 2015 7:00 am | by MIT, David Chandler | Videos | Comments

When disturbed or attacked, bombardier beetles produce an internal chemical explosion in their abdomen and then expel a jet of boiling, irritating liquid toward their attackers. Researchers had been baffled by the half-inch beetles’ ability to produce this noxious spray while avoiding any physical damage. Now, that conundrum has been solved.

Female Brains Up Reward Response at Sight of Crying Babies

May 1, 2015 7:00 am | by Indiana Univ. Bloomington | News | Comments

Researchers studying postpartum depression have found that the hormone oxytocin increased activation in a reward-sensitive area of the brain when women viewed images of crying infants, but not when they viewed images of smiling ones. The researchers say oxytocin might spark the motivation to help an upset baby.

Nanoengineering May Be Key to Reducing Foodborne Bacteria

April 30, 2015 3:00 pm | by Wayne State Univ. | News | Comments

Nearly half of foodborne illnesses in the U.S. from 1998 through 2008 have been attributed to contaminated fresh produce. The current strategy remains industrial washing of the product in chlorinated water. However, because of sanitizer ineffectiveness there is an urgent need to identify alternative antimicrobials, particularly those of natural origin.

Turning All Donated Blood into a Universal Type

April 30, 2015 7:00 am | by ACS | News | Comments

Every day, thousands of people need donated blood. But only blood without A- or B-type antigens, such as type O, can be given to all of those in need, and it’s usually in short supply. Now, scientists are reporting an efficient way to transform A and B blood into a neutral type that can be given to any patient.

Urine Provides Clues to How Obesity Causes Disease

April 30, 2015 7:00 am | by Imperial College London | News | Comments

Scientists have identified chemical markers in urine associated with body mass, providing insights into how obesity causes disease. A new study shows that obesity has a “metabolic signature” detectable in urine samples, pointing to processes that could be targeted to mitigate its effects on health.

Less Pollution May Be Linked to Heavier Babies

April 29, 2015 3:00 pm | by Associated Press | News | Comments

Women in the Chinese capital in the final stage of pregnancy during the 2008 Beijing Olympics— when officials strictly controlled air pollution— gave birth to heavier babies than in years when the city was smoggier. The babies were, on average, 23 grams heavier than those born either a year earlier or a year later.

In the Beginning, Water May Have Been Abundant

April 29, 2015 7:00 am | by Harvard-Smithsonian Center for Astrophysics | News | Comments

How soon after the Big Bang could water have existed? Not right away, because water molecules contain oxygen and oxygen had to be formed in the first stars. But, new theoretical work finds that, despite the complications, water vapor could have been just as abundant in pockets of space a billion years after the Big Bang as it is today.

Forty Years On, Agent Orange’s Harm Remains

April 28, 2015 3:25 pm | by Seth Augenstein, Digital Reporter | News | Comments

The final shots in the Vietnam War were fired 40 years ago this week. But for some, the war never ended. Thousands of veterans have been haunted physically by the use of the defoliant Agent Orange. From cancers to neurological diseases, to diabetes and congenital birth defects in children, Agent Orange has been tied to a litany of diseases for those who served in Southeast Asia– and even those who never set foot in the country.
