A Few 'Problem Wells' Source of Greenhouse Gas

April 15, 2014 7:00 am | by Purdue Univ. | News | Comments

High levels of the greenhouse gas methane were found above shale gas wells at a production point not thought to be an important emissions source, according to a study. The findings could have implications for the evaluation of the environmental impacts from natural gas production.


Scientists Examine World's Most Popular Drug: Caffeine

In a new video, researchers look at the science behind the world's most popular drug, caffeine, including why it keeps you awake and how much is too much.


Researchers Redirect Sunlight to Urban Alleys

April 15, 2014 7:00 am | by The Optical Society | News | Comments

Egyptian researchers have developed a corrugated, translucent panel that redirects sunlight onto narrow streets and alleyways. The panel is mounted on rooftops and hung over the edge at an angle, where it spreads sunlight onto the street below.


France Casts DNA Dragnet in Rape Case

April 15, 2014 7:00 am | by Associated Press, Lori Hinnant | News | Comments

French investigators have begun taking DNA samples from 527 male students and staff at a high school— including boys as young as 14— as they search for the assailant who raped a teenage girl on the closed campus.


Puget Sound’s Waters Come from Deep Canyon

April 15, 2014 7:00 am | by Univ. of Washington | News | Comments

The headwaters for Puget Sound’s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest’s inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales.


Nutrient-rich Forests Store More Carbon

April 15, 2014 7:00 am | by International Institute for Applied Systems Analysis | News | Comments

Forests growing in fertile soils, with ample nutrients, are able to sequester about 30 percent of the carbon they take up during photosynthesis. In contrast, forests growing in nutrient-poor soils may retain only 6 percent of that carbon.


Researchers ID Four New Killer Sponges

April 15, 2014 7:00 am | by Monterey Bay Aquarium Research Institute | News | Comments

Scientists first discovered that some sponges are carnivorous about 20 years ago. Since then only seven carnivorous species have been found in all of the northeastern Pacific. Now, a paper describes four new species of carnivorous sponges living on the deep seafloor, from the Pacific Northwest to Baja California.

Imagine you are an astronaut on the ISS and a fleck of dust gets in your eye. How do you wash it out? Engineers came up with the idea seen in this picture.


Technique Can Reverse-engineer Developing Lung

April 14, 2014 12:54 pm | by Stanford School of Engineering | News | Comments

In a feat of reverse tissue engineering, researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform a myriad of different biological tasks.


Long-term Antibiotic Use Linked to Weight Gain

April 14, 2014 12:43 pm | by American Society for Microbiology | News | Comments

Scientists have unearthed still more evidence that antibiotics can contribute to obesity. New research suggests that patients on long-term antibiotic treatment gained weight and had significant changes in their gut microbiota.


Material Stores Sun's Heat for Power When It's Cloudy

April 14, 2014 12:26 pm | by MIT, David Chandler | News | Comments

The problem with solar power is that sometimes the sun doesn’t shine. Now, scientists have come up with an ingenious workaround— a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand.


Silly Putty Ingredient Grows Better Stem Cells

April 14, 2014 12:14 pm | by Univ. of Michigan | News | Comments

Researchers coaxed human embryonic stem cells to turn into working spinal cord cells more efficiently by growing the cells on a soft, ultrafine carpet made of a key ingredient in Silly Putty.
