Men and women may share more similarities than previously thought when it comes to the risk factors for major depression, according to a new study by Virginia Commonwealth University researchers.
In the January issue of the American Journal of Psychiatry, researchers reported that although there is a wide range of risk factors for depression that can act at different stages of development, the patterns of causes of depression for men and women are fairly similar. Some of these
Although the story on glacier fluctuations in northwestern North America over the last 10,000 years has remained largely unchanged for decades, new evidence discovered by a University of Alberta researcher will rewrite that glacial history and offer clues about our climate history during the last several thousand years.
Glacier fluctuations are sensitive indicators of past climate change, yet little is known about glacier activity in Pacific North America during the first millenniu
Project aims to consolidate information, coordinate efforts
E.coli is one of the most important model organisms for molecular science today and is arguably the single organism about which the most is known. The genes of higher-level plants and animals, even humans, are often understood by their similarity to E. coli genes. As such, the accuracy and completeness of E.coli genome information is of great importance to the scientific community.
In an attempt to consolidate
A multicenter international study, including Johns Hopkins, has found that after surgery for thyroid cancer, giving genetically engineered human thyroid-stimulating hormone (rhTSH) before radioiodine treatment avoids the previous need to stop thyroid replacement therapy and the miserable side effects that go with it.
The study, led by Paul Ladenson, M.D., director of the Division of Endocrinology at The Johns Hopkins University School of Medicine, and Furio Pacini at the Universi
When it comes to how much automobiles pollute, some makes are cleaner than others, according to new research.
A study using data on nearly 4 million cars that underwent government-mandated emissions test in three states found that cars manufactured by German auto maker BMW were the least likely to fail these state pollution tests. Cars manufactured by Hyundai, Mitsubishi, Chrysler and GM were most likely to fail.
While other studies have analyzed data from state
Galaxy’s warp explained by Magellanic Clouds plowing through dark matter halo
The most prominent of the Milky Way’s satellite galaxies – a pair of galaxies called the Magellanic Clouds – appears to be interacting with the Milky Way’s ghostly dark matter to create a mysterious warp in the galactic disk that has puzzled astronomers for half a century.
The warp, seen most clearly in the thin disk of hydrogen gas permeating the galaxy, extends across the en
Cross-cultural study compares cognitive development in 3-to-5-year-olds
Chinese children are better able to control impulsive behaviour than their North American counterparts, a new Queen’s University study shows.
But the development of a related ability – being able to connect what other people do with what they are thinking and feeling – shows no cross-cultural difference, says psychologist Mark Sabbagh, who led the international research team.

Corporations like Enron that overemphasize outcomes such as profits might make their leaders blind to ethics and limit their abilities to recognize ethical or moral issues when they surface, according to a University of Washington study.
Scott Reynolds, an assistant professor of business ethics in the UW Business School, examined why some managers recognize a situation as involving moral issues whiles others do not. His research demonstrates it is not always obvious when an issue
Scientists characterize large numbers of independently expressed, non-protein-coding RNA genes in the introns of protein-coding genes
Scientists from the Chinese Academy of Sciences have performed a comprehensive analysis of small, non-protein-coding RNAs in the model nematode, C. elegans. They characterize 100 heretofore-undescribed transcripts, including two novel classes; they provide insights into the genomic structure and transcriptional regulation of non-coding RNAs; an
Mayo Clinic Cancer Center researchers report aggressive surgical removal of as much cancer as possible throughout the abdomen in ovarian cancer patients is the best option for most women. Results of the study are published in the January issue of Obstetrics & Gynecology.
“This study provides further evidence that surgery to remove as much tumor as possible at the initial operation is the best option for most patients,” says William Cliby, M.D., Mayo Clinic gynecologic oncologist a
Dental implants, an artificial tooth root surgically anchored into a jaw to hold a replacement tooth or several teeth in place, offer a permanent solution to replace lost or extracted teeth. Implants have become a treatment of choice for some patients to eliminate the need for removable partial or complete dentures. Other patients choose implants for esthetic purposes or to conserve tooth structure in an otherwise cavity-free mouth.
However, according to a recent report in the Novembe
A spoon full of sugar may help the medicine go down, but most dentists would likely encourage parents to skip that step when treating a child’s illness. However, most parents might not realize that even without the sugar, some children’s medicines may cause cavities while they’re fighting other health issues, according to a report in the January/February issue of General Dentistry, the Academy of General Dentistry’s (AGD) clinical, peer-reviewed journal.

RIT/STScI astronomer presents at American Astronomical Society meeting
A massive cluster of red supergiants–super-sized stars on the verge of exploding–was recently discovered in the Milky Way by a group of stronomers using infrared technology to penetrate the thick dust that cloaks much of the galaxy.
Only a few hundred such stars are known to exist in the galaxy, with the previous largest collection of them containing only five. These are the biggest stars: a singl
Contrary to popular thinking in athletics, traditional neck muscle resistance training may not protect athletes from head injuries.
For eight weeks, kinesiologists at Temple University worked with male and female Division I intercollegiate soccer players to see if a resistance training program would reduce the player’s head acceleration during impact. According to Ryan Tierney PhD, director of Temple’s Graduate Athletic Training Program, head impacts experienced during
How does matter spiral its way to the center of a galaxy and into the mouth of a supermassive black hole? A new study provides the best glimpse yet at the death spiral of material as it descends into the core of a galaxy hosting a large black hole. The study predicts that, barring obstructions, the galactic debris will take about 200,000 years to make a one-way trip through the inner regions of the galaxy and into oblivion.

On 13 January the new Carl-Ivar Brändén Building (CIBB) will be inaugurated on the Polygone Scientifique Campus in Grenoble, France. The CIBB will be operated as a collaboration between major international and national partners based in Grenoble and is a further step in the development of the region as a European centre of excellence for structural biology.
The CIBB comprises two complementary units: the Partnership for Structural Biology (PSB), whose members include the Europea
