Energy Savings – Easy as Dirt, Heat, Pressure
By using common materials found pretty much anywhere there is dirt, a team of Michigan State University researchers have developed a new thermoelectric material. (more…)

Bothered by Negative, Unwanted Thoughts? Just Throw Them Away
COLUMBUS, Ohio — If you want to get rid of unwanted, negative thoughts, try just ripping them up and tossing them in the trash.
In a new study, researchers found that when people wrote down their thoughts on a piece of paper and then threw the paper away, they mentally discarded the thoughts as well.
On the other hand, people were more likely to use their thoughts when making judgments if they first wrote them down on a piece of paper and tucked the paper in a pocket to protect it. (more…)
Astronomers Pin Down Origins of “Mile Markers” for Expansion of Universe
COLUMBUS, Ohio – A study using a unique new instrument on the world’s largest optical telescope has revealed the likely origins of especially bright supernovae that astronomers use as easy-to-spot “mile markers” to measure the expansion and acceleration of the universe.
In a paper to appear in the Astrophysical Journal, researchers describe observations of recent supernova 2011fe that they captured with the Large Binocular Telescope (LBT) using a tool created at Ohio State University: the Multi-Object Double Spectrograph (MODS). (more…)
For Ancient Birds, Wing Feathers Were a Serious Drag
A new study of ancient feathers adds weight to the theory that primitive birds — close relatives of feathered dinosaurs — were far less versatile fliers than their modern descendants. (more…)
BOSS Quasars Unveil a New Era in the Expansion History of the Universe
Berkeley Lab scientists and their Sloan Digital Sky Survey colleagues use quasars to probe dark energy over 10 billion years in the past
BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on the spectra of over 48,000 quasars with redshifts up to 3.5, meaning that light left these active galaxies up to 11.5 billion years in the past.

Less Wait Time for Safe Travel Could Reduce Drinking and Driving in People with ‘Urgency’ Personality Trait, Says MU Researcher
COLUMBIA, Mo. — Saving bar patrons’ time on their commute home could save lives. A pair of studies by University of Missouri psychologists found that people who reported drinking and driving also exhibited “urgency,” or a lack of emotional self-control, especially while drinking. This suggests that some people when intoxicated may be more likely to choose the convenience of driving themselves home instead of waiting for a taxi, said Denis McCarthy, associate professor of psychology at MU.
“Our study correlated urgency, a specific type of impulsivity, to drinking and driving,” McCarthy said. “Individuals with a high degree of urgency tend to act impulsively when they are in both positive and negative emotional states. By looking at personality traits that correlate with drinking and driving, we can help people understand how their personalities might incline them to choose the risk of driving after drinking. Once a person knows this, they can decide to take extra care to moderate their drinking or be prepared to call a cab, hop on a bus or ask a designated driver for help.” (more…)
Can Life Emerge on Planets Around Cooling Stars?
Astronomers find planets in strange places and wonder if they might support life. One such place would be in orbit around a white or brown dwarf. While neither is a star like the sun, both glow and so could be orbited by planets with the right ingredients for life. (more…)
Native Delaware: Parenting’s toll
Stewart studies birds to understand trade-offs between reproduction, immunity
Does parenting take a toll on the immune system?
If you’ve ever been the parent of a newborn who demanded to be fed every three to four hours, your gut instinct tells you the answer is an absolute, unequivocal yes.
University of Delaware post-doctoral researcher Ian Stewart is conducting research to answer this question a bit more scientifically. His subjects – tree swallows – make human parents look like slouches. Both the mother and father tree swallow feed their hatchlings every five minutes, 12 hours a day. (It should be noted, though, that their parenting gig is much shorter than ours — after 17 or 18 days the young leave the nest.) (more…)
