FORT DAVIS, Texas — Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin’s McDonald Observatory to measure the mass of what may be the most massive black hole yet — 17 billion times our sun’s mass — in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy’s mass, rather than the usual 0.1 percent. This galaxy and several more in the same study could change theories about how black holes and galaxies form and evolve. The work will appear in the journal Nature on Nov. 29.
NGC 1277 lies 220 million light-years away in the constellation Perseus. The galaxy is only 10 percent the size and mass of our Milky Way. Despite NGC 1277’s diminutive size, the black hole at its heart is more than 11 times as wide as Neptune’s orbit around the sun. (more…)
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…)
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…)
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…)
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…)
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.

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…)
