Some major trucking companies are turning to natural gas to fuel their fleets— and to earn "green" credit among customers. But celebrating lower emissions could be premature.

Serious Pediatric Mental Problems on Decline, More Seek Help

May 21, 2015 3:00 pm | by Associated Press, Marilynn Marchione | News | Comments

Contrary to public perception and horrific cases that make headlines, serious mental problems are declining among the nation's youth, and there has been a big rise in how many are getting help, a new study finds. The study is mostly good news: more children and teens are taking mental health medicines than ever before, but more also are getting therapy, not just pills.

Chamomile Tea Lowers Death Risk in Some Older Women

May 21, 2015 3:00 pm | by The Univ. of Texas Medical Branch at Galveston | News | Comments

Chamomile is one of the oldest, most-widely used and well-documented medicinal plants in the world and has been recommended for a variety of healing applications. Now, research has found that drinking chamomile tea was associated with a decreased risk of death from all causes in Mexican-American women over 65.


Ability of GM Crops to Deter Pests Diminishes

May 21, 2015 3:00 pm | by North Carolina State Univ. | News | Comments

A new study has found that the toxin in a widely used genetically modified (GM) crop is having little impact on the crop pest called corn earworm– which is consistent with predictions made almost 20 years ago that had been largely ignored. The study may be a signal to pay closer attention to warning signs about the development of resistance in agricultural pests to GM crops.

Donate Your Body to Science, Without Dying First

May 21, 2015 7:00 am | by Michelle Taylor, Editor-in-Chief | Blogs | Comments

Typically, when someone chooses to donate their body to science, it’s as a cadaver. While cadavers are great learning tools, there’s something to be said for having access to living, breathing humans. Now, a group of scientists has discovered a way to circumvent the “you must be dead first” rule.

Skipping Meals May Lead to Abdominal Weight Gain

May 20, 2015 3:00 pm | by Ohio State Univ. | News | Comments

A new study in animals suggests that skipping meals sets off a series of metabolic miscues that can result in abdominal weight gain. In the study, mice that ate all of their food as a single meal and fasted the rest of the day developed insulin resistance in their livers. When the liver doesn’t respond to insulin signals telling it to stop producing glucose, that extra sugar in the blood is stored as fat.

Light-emitting, Transparent Paper Key to Flexible Electronics

A new step has been made toward bendable electronics. Scientists have developed the first light-emitting, transparent and flexible paper out of environmentally friendly materials via a simple, suction-filtration method.


Good Soil Can Offset Impacts of Global Warming

May 20, 2015 3:00 pm | by Yale School of Forestry & Environmental Studies | News | Comments

Maintaining a healthy and diverse soil community can buffer natural ecosystems against the damaging impacts of global warming. In a long-term study, researchers showed that small soil animals can limit the effects of climate change, which would otherwise stimulate the loss of carbon from the soil into the atmosphere.

Robot IDs Beer Correctly Every Time

May 20, 2015 7:00 am | by Inside Science News Service, Lisa Marie Potter | News | Comments

Machines mimicking a human's sense of taste are going on a beer-tasting binge. Despite being called electronic tongues, these devices aren't party robots, pouring beer onto wagging, mechanical tongues— they accurately distinguished between four styles of lager beer 100 percent of the time.

Cancer Drugs May Treat Down Syndrome, Brain Disorders

May 20, 2015 7:00 am | by Univ. of Michigan | Videos | Comments

A class of FDA-approved cancer drugs may be able to prevent problems with brain cell development associated with disorders including Down syndrome and Fragile X syndrome, researchers have found. They showed that giving the leukemia drugs nilotinib or bafetinib to fly larvae with the equivalent of Fragile X prevented the wild overgrowth of neuron endings associated with the disorder.

'Redesigned' Antibodies May Neutralize HIV

May 20, 2015 7:00 am | by Vanderbilt Univ. | News | Comments

With the help of a computer program called "Rosetta," researchers have "redesigned" an antibody that has increased potency and can neutralize more strains of the AIDS-causing human immunodeficiency virus (HIV) than can any known natural antibody. The find suggests that computer-redesigned antibodies may speed the search for an effective therapy or vaccine for a virus that so far has eluded all attempts to eradicate it.

Nanosponges Clean Up MRSA Infections

May 18, 2015 3:00 pm | by UC San Diego | News | Comments

Nanoengineers have developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA, an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA— without the use of antibiotics.

Sugar Could Make Synthetic Opium

May 18, 2015 3:00 pm | by Concordia Univ. | News | Comments

Moonshiners and home-brewers have long used yeast to convert sugar into alcohol. Those methods could also be adapted for something more significant: the production of drugs including opiates, antibiotics and anti-cancer therapeutics. According to new studies yeast can be engineered to convert sugar to alkaloids— plant-derived compounds such as codeine and morphine, naturally produced in the opium poppy.
