Past abuse leads to loss of gray matter in brains of adolescents
Adolescents who were abused and neglected have less gray matter in some areas of the brain than young people who have not been maltreated, a new Yale School of Medicine study shows. The brain areas impacted by maltreatment may differ between boys and girls, may depend on whether the youths had been exposed to abuse or neglect, and may be linked to whether the neglect was physical or emotional.

Confidence is key to womens spatial skills
Boosting a woman's confidence makes her better at spatial tasks, University of Warwick scientists have found, suggesting skills such as parking and map-reading could come more easily if a woman is feeling good about herself. Previous studies have established that women are slower and less accurate than men on a range of spatial tasks.

Blood protein EPO involved in origin and spread of cancer
Researchers at Karolinska Institutet have demonstrated that a growth hormone, PDGF-BB, and the blood protein EPO are involved in the development of cancer tumours and that they combine to help the tumours proliferate in the body. These new preclinical findings offer new potential for inhibiting tumour growth and bypassing problems of resistance that exist with many drugs in current use.

Where have all the quasars gone?
An international team of astronomers has discovered two gigantic black holes with masses about 10 billion times the mass of our sun. These black holes have a mass more than 50 per cent greater than any other previously measured. "They may be the dormant remains of quasars that were extremely luminous billions of years ago," said Professor James Graham , director of the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto and founding member of the team behind the discovery.

Male infertility could soon have a boost through new treatments at a sub-DNA 'epigenetic' level, according to researchers from The Australian National University. The research team, led by Professor David Tremethick of The John Curtin School of Medical Research at ANU, have uncovered a new mechanism of gene activation which will have important implications in understanding how cellular differentiation is achieved.

Tiny genetic variation can predict ovarian cancer outcome
Yale Cancer Center researchers have shown that a tiny genetic variation predicts chances of survival and response to treatment for patients with ovarian cancer. The findings, published in the journal Oncogene, provide new insights into the biology of a new class of cancer marker and suggest a genetic test may help guide the treatment of women with ovarian cancer.

Most massive black holes ever found could be relics of the brightest quasars
ANN ARBOR, Mich.-At 10 billion times the mass of our sun, two newly discovered black holes are the most massive that astronomers have ever found. A paper on the discovery, which involved a University of Michigan researcher, is published in the Dec. 8 edition of Nature. Black holes are dense concentrations of matter that produce such strong gravitational fields that not even light can escape.

When brands seem like people, people act accordingly
From the Michelin Man to the Pillsbury Doughboy, anthropomorphized brands have often been used by companies eager to put a personal face on their products. Now new research shows that thinking about brands as people can make you either take on the brand's characteristics or display the opposite characteristics, depending on how you feel about the brand.

Scientists at King's have found that the body's surveillance for cancer causing damage and its response to allergies share a common pathway, according to research published in the journal, Science. The cells that line the body's surfaces, known as epithelial cells, are exposed to potentially cancer causing damage every day, such as the effects of UV light and tobacco smoke.

Discoveries of new planets just keep coming and coming. Take, for instance, the 18 recently found by a team of astronomers led by scientists at the California Institute of Technology (Caltech). "It's the largest single announcement of planets in orbit around stars more massive than the sun, aside from the discoveries made by the Kepler mission," says John Johnson, assistant professor of astronomy at Caltech and the first author on the team's paper, which was published in the December issue of The Astrophysical Journal Supplement Series.

Londoners and Scots are less likely to support reductions to immigration than people in the Midlands and Wales, new research by Oxford University's Migration Observatory shows. In their recent public opinion survey undertaken with Ipsos MORI, the Observatory highlights regional findings which suggest that there may not be a direct link between the scale of immigration to an area and public support for cuts to immigration.

Study of wolves will help scientists predict climate effects on endangered animals
Scientists studying populations of gray wolves in the USA's Yellowstone National Park have developed a way to predict how changes in the environment will impact on the animals' number, body size and genetics, amongst other biological traits. Writing in the journal Science , the researchers say they now have a way to predict the extent to which climate change could simultaneously impact animal numbers and the ways in which animals are likely to evolve.

Antioxidant-rich diet may reduce stroke risk in women
Women who ate an antioxidant-rich diet containing fruits, vegetables and grains had fewer strokes regardless of whether they had a previous history of cardiovascular disease, according to a new study by researchers at Karolinska Institutet. The findings are reported in Stroke, scientific journal of the American Heart Association.

Update on gas pipeline testing near campus
Just before Thanksgiving, PG&E work crews finished the hydrostatic pressure testing of gas transmission pipeline 132 near the Stanford campus. Two sections of pipe, called T-30 and T-31, were tested to more than 1.5 times their maximum allowable operating pressure. In the run up to the final test, both pipe sections experienced problems.

CO2 levels plunged as Antarctica froze
A Yale University-led research team has found evidence that carbon dioxide levels in Earth's atmosphere plunged prior to and during the initial icing of Antarctica, about 34 million years ago. The new findings provide further evidence of atmospheric carbon dioxide's role as a major trigger of global climate change.

Stem cell-like cells from human skin
Researchers investigating how stem cells can be used to regenerate dental tissue have discovered a way to produce cells with stem cell-like characteristics from the most common type of human skin cell in the epidermis . These skin cells, called keratinocytes, form the outermost layer of skin and can be cultured from discarded skin tissues or biopsy specimens.

Strange New "Species" of Ultra-Red Galaxy Discovered
Cambridge, MA - In the distant reaches of the universe, almost 13 billion light-years from Earth, a strange species of galaxy lay hidden. Cloaked in dust and dimmed by the intervening distance, even the Hubble Space Telescope couldn't spy it. It took the revealing power of NASA's Spitzer Space Telescope to uncover not one, but four remarkably red galaxies.

Yale discovery of ’young’ supermassive black holes challenges current theory
Astronomers at Yale University have discovered what appear to be three fast-growing supermassive black holes in a relatively young, still-forming galaxy. The discovery raises the possibility that this type of black hole continues to form billions of years after the Big Bang, challenging current theory.

The revival of a 150-year-old theory on how the human ear protects itself from damage caused by loud sounds could lead to better noise protection says a researcher from The Australian National University. In a paper published in the Journal of Hearing Science, Andrew Bell of the Research School of Biology at ANU urges reconsideration of the long-discarded 'pressure theory' that explains inconsistencies that have long puzzled hearing researchers.

Protein sheds insight into vCJD
A protein linked to the immune system could play a key role in helping scientists understand how vCJD spreads throughout the body. The disease occurs after corrupted proteins - known as prions - accumulate in the spleen, lymph nodes and tonsils. The prions then spread to the brain where the disease destroys nerve cells.
