New research identifies age, gender, personality and how often people drive as potential risk factors for becoming distracted while driving. Young men, extroverted or neurotic people, and people who drive more often were more likely to report being distracted, while older women and those who felt that they could control their distracted behavior were less likely to report distraction.
For researchers pursuing the primordial history of oxygen in Earth's atmosphere, a new study might sour some "Eureka!" moments. A contemporary tool used to trace oxygen by examining ancient rock strata can produce false positives, according to the study, and the wayward results can mask as exhilarating discoveries.
EVANSTON, Ill. --- A Northwestern University research team is the first to capture on video organic nanoparticles colliding and fusing together. This unprecedented view of "chemistry in motion" will aid Northwestern nanoscientists developing new drug delivery methods as well as demonstrate to researchers around the globe how an emerging imaging technique opens a new window on a very tiny world.
With concerns over moving to a clean energy platform worldwide with electric vehicles and renewables, the energy we consume, or should we say do NOT consume, is as important as the green energy we produce. Thus, solid state lighting, more efficient than incandescent and fluorescent bulbs, based upon light emitting diodes (LED) is touted as the solution. However, LEDs struggle to deliver high brightness for the shorter-wavelength end of lighting needs. And emitted short wavelengths facilitate white light through known phosphor downconverters.
The University of Surrey has developed a new and cost-effective catalyst to recycle two of the main causes behind climate change - carbon dioxide (CO2) and methane (CH4).
In a study published by the Applied Catalysis B: Environmental, scientists have described how they created an advanced nickel-based catalyst strengthened with tin and ceria, and used it to transform CO2 and CH4 into a synthesis gas that can be used to produce fuels and a range of valuable chemicals.
CAMBRIDGE, Mass. -- In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel -- such as wood, brush or dung -- that is collected with significant time and effort.
Now, a new chemical composite developed by researchers at MIT could provide an alternative. It could be used to store heat from the sun or any other source during the day in a kind of thermal battery, and it could release the heat when needed, for example for cooking or heating after dark.

The thin veneer of Earth's surface that stretches from the top of the forest canopy to the base of bedrock is known as the "critical zone." It's where fresh water flows, rock turns to soil and life flourishes.
Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have revealed the pathology of cells and structures stricken by optic nerve hypoplasia, a leading cause of childhood blindness in developed nations.
The discovery in a rodent model may provide insight into what happens in the visual systems of children born with a condition that prevents the optic nerve from fully developing. The condition is also associated with autism spectrum disorder.
PHILADELPHIA (Nov.16, 2017) - Researchers identified a new way to lower the risk of complications after joint surgery, using a simple blood test. Patients with diabetes are more likely to need joint replacement surgery but also have a greater risk of serious complications after surgery, including heart attack, stroke, and wound infections, because of their underlying diabetes.
Researchers at UC San Francisco have shown how the Bengalese finch, a domesticated songbird, can learn to tweak its song in specific ways depending on context, which could shed light on how the human brain learns to apply different rules depending on the situation, and have implications for understanding human language and movement disorders.
