International study shows some asteroids live in own little worlds

While the common perception of asteroids is that they are giant rocks lumbering about in orbit, a new study shows they actually are constantly changing "little worlds" that can give birth to smaller asteroids that split off to start their own lives as they circle around the sun.

Sunlight spawns many binary and 'divorced' binary asteroids

The asteroid belt between Mars and Jupiter is often depicted as a dull zone of dead rocks with an occasional wayward speedster smashing through on its way toward the sun.

A new study appearing in the Aug. 26 issue of the journal Nature paints a different picture, one of slow but steady change, where sunlight gradually drives asteroids to split in two and move far apart to become independent asteroids among the millions orbiting the sun.

The strange case of solar flares and radioactive elements

The strange case of solar flares and radioactive elements

It's a mystery that presented itself unexpectedly: The radioactive decay of some elements sitting quietly in laboratories on Earth seemed to be influenced by activities inside the sun, 93 million miles away.

Is this possible?

System uses electrical trickery on the brain to induce realistic spaceflight effects

HOUSTON – (Aug. 24, 2010) – What does it feel like to return to Earth after a long stay in space? Until now, it has been difficult during astronaut training to realistically simulate the dizzying effects the human body can experience.

Dr. Steven Moore leads a research group that has developed a Galvanic vestibular stimulation (GVS) system that safely induces the sensory and mobility disturbances commonly experienced by astronauts after returning to Earth's gravity, making it an excellent operational training tool.

See amazing new sun images from NJIT's Big Bear Solar Observatory

NJIT Distinguished Professor Philip R. Goode and the Big Bear Solar Observatory (BBSO) team have achieved "first light" using a deformable mirror in what is called adaptive optics at Big Bear Solar Observatory (BBSO). Using this equipment, an image of a sunspot was published yesterday on the website of Ciel et l'Espace, as the photo of the day: http://www.cieletespace.fr/node/5752

Cultural capital is key to preparing for college and getting into a good school

A study by Kristin Jordan, a doctoral student in Indiana University Bloomington's Department of Sociology, found that students with low-income or minority status do not prepare for college in the same way as their more privileged counterparts, regardless of their academic ability or plans to attend college. The less privileged students are over-represented in community colleges while their counterparts are more likely to attend more selected schools.

Drug addicts get hooked via prescriptions, keep using 'to feel like a better person,' research shows

BUFFALO, N.Y. -- If you want to know how people become addicted and why they keep using drugs, ask the people who are addicted.

Thirty-one of 75 patients hospitalized for opioid detoxification told University at Buffalo physicians they first got hooked on drugs legitimately prescribed for pain.

Another 24 began with a friend's left-over prescription pills or pilfered from a parent's medicine cabinet. The remaining 20 patients said they got hooked on street drugs.

Electronic tracking system can improve follow-up after an abnormal Pap test

(Boston) – Researchers from Boston University School of Medicine (BUSM) report that physicians who use an automated, electronic medical record (EMR) tracking system to follow-up on patients with an abnormal Pap test could increase the number of women who achieved diagnostic resolution and have women achieve resolution in less time than using traditional methods. These findings appear in the Journal of General Internal Medicine.

NASA's LRO reveals 'incredible shrinking moon'

GREENBELT, Md. -- Newly discovered cliffs in the lunar crust indicate the moon shrank globally in the geologically recent past and might still be shrinking today, according to a team analyzing new images from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft. The results provide important clues to the moon's recent geologic and tectonic evolution.
