Super-massive black holes observed at the center of galaxies Posted: 11 Dec 2009 05:00 PM PST An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate.

Cataloging all that goes wrong in a cancer cell Posted: 11 Dec 2009 05:00 PM PST A team of scientists has produced a systematic listing of the ways a particular cancerous cell has "gone wrong," giving researchers a powerful tool that eventually could make possible new, more targeted therapies for patients.

Pathological gambling may be successfully treated with medications for substance addiction Posted: 11 Dec 2009 05:00 PM PST Pathological gambling can be successfully treated with medications that decrease urges and increase inhibitions, according to researchers. They found positive outcomes in gamblers treated with medications often used for substance addictions.

RXR activation: Hope for new Parkinson's disease treatment Posted: 11 Dec 2009 05:00 PM PST Researchers have investigated the potential of RXR ligands for the treatment of Parkinson's disease. In a new study, the scientists describe the use of two cellular models of Parkinsonian damage to explore the neuroprotective function of the two RXR ligands LG268 and XCT.

Astronaut balancing act: Training to help explorers adapt to a return to gravity Posted: 11 Dec 2009 05:00 PM PST Challenges associated with long-duration spaceflight do not end with landing. Astronauts often suffer from balance problems that lead to dizziness and difficulty standing, walking and turning corners when they return to normal gravity. Researchers are developing techniques, using a treadmill and simulated balance disturbances, to help astronauts adapt to a new gravity environment. The techniques could also have benefits for Earth-bound populations such as the elderly.

Old math reveals new thinking in children's cognitive development Posted: 11 Dec 2009 05:00 PM PST Five-year-olds can reason about the world from multiple perspectives simultaneously, according to a new theory by researchers in Japan and Australia. Using an established branch of mathematics called Category Theory, the researchers explain why specific reasoning skills develop in children at certain ages, particularly at age five. The new theory shows that these reasoning skills have similar profiles of development because they involve related sorts of processes.

Nerve-cell transplants help brain-damaged rats fully recover lost ability to learn Posted: 11 Dec 2009 02:00 PM PST Nerve cells transplanted into brain-damaged rats helped them to fully recover their ability to learn and remember, probably by promoting nurturing, protective growth factors, according to a new study.

MRI detects breast cancer at earlier stage, study shows Posted: 11 Dec 2009 02:00 PM PST Magnetic resonance imaging (MRI) coupled with mammography detects almost all cancers at an early stage, thereby reducing the incidence of advanced stage breast cancer in high-risk women.

Unexpected weakness in H1N1's method for evading detection by the immune system Posted: 11 Dec 2009 02:00 PM PST The H1N1 influenza virus has been keeping a secret that may be the key to defeating it and other flu viruses as well. Researchers have found what they believe is a weakness in H1N1's method for evading detection by the immune system.

Genetic variations indicate risk of recurrence, secondary cancer among head and neck cancer patients Posted: 11 Dec 2009 02:00 PM PST Eighteen single-point genetic variations indicate risk of recurrence for early-stage head and neck cancer patients and their likelihood of developing a second type of cancer, researchers report.

Surgery on beating heart thanks to robotic helping hand Posted: 11 Dec 2009 02:00 PM PST If you've been waiting for the day to arrive when computers actually start performing surgery, that moment might soon be upon us. Scientists have developed a computerized 3-D model that allows surgeons to use robotics to operate on a beating heart.

Fit teenage boys are smarter -- but muscle strength isn't the secret, study shows Posted: 11 Dec 2009 02:00 PM PST In the first study to demonstrate a clear positive association between adolescent fitness and adult cognitive performance, researchers find that better aerobic health among teenage boys correlates to higher scores on a range of intelligence tests -- and more education and income later in life.

Universal quantum mechanism: Physicists find reappearing quantum trios Posted: 10 Dec 2009 09:00 PM PST Using atoms at temperatures colder than deep space, physicists have delivered overwhelming proof for a 1970 theory that was largely scoffed at when it first appeared. They offers experimental proof of a universal quantum mechanism that causes trios of particles to appear and reappear at higher energy levels in an infinite progression. The triplets, or trimers, form in special cases where pairs cannot.

New inherited eye disease discovered Posted: 10 Dec 2009 09:00 PM PST Researchers have found the existence of a new, rare inherited retinal disease. Now the search is on to find the genetic cause, which investigators hope will increase understanding of more common retinal diseases.

New light vision goggles light up the night Posted: 10 Dec 2009 09:00 PM PST Vanderbilt LifeFlight is now using technology once reserved for military operations or secret spy missions. With the ability to enhance light 10,000 times, the air ambulance service's new night vision goggles essentially turn night into day.

Ancient Book of Mark Found Not So Ancient After All Posted: 10 Dec 2009 09:00 PM PST A biblical expert, together with experts in micro-chemical analysis and medieval bookmaking, has concluded that one of the University of Chicago Library's most enigmatic possessions is a forgery.

Action on climate change compatible with long-term U.S. economic growth Posted: 10 Dec 2009 09:00 PM PST Measures being proposed by the U.S. Climate Action Partnership to curb greenhouse gas emissions are unlikely to affect potential long-term economic growth in the United States, according to a study.

Forest service early warning system Posted: 10 Dec 2009 09:00 PM PST A national early warning system designed to assist land managers in rapidly detecting threats to forest health has been developed. A new article describes the vision and progress of the system.
