A hallmark of the individual is the cultivation of personal interests, but for some people, their intellectual pursuits might actually be genetically predetermined. Survey results published by Princeton University researchers in the journal PLoS ONE suggest that a family history of psychiatric conditions such as autism and depression could influence the subjects a person finds engaging.

A longstanding California occupational safety program requiring all businesses to eliminate workplace hazards can help prevent injuries to workers, but only if it is adequately enforced, according to a new study by the RAND Corporation.
The first-ever evaluation of the California Injury and Illness Prevention Program found evidence that the program reduces workplace injuries, but only at businesses that had been cited for not addressing the regulation's more-specific safety mandates.
EAST LANSING, Mich. -- In the current issue of Science, researchers at Michigan State University demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations.
University of Rochester Medical Center researchers have discovered new links between leukemia cells and cells involved in bone formation, offering a fresh perspective on how the blood cancer progresses and raising the possibility that therapies for bone disorders could help in the treatment of leukemia.
A multi-university research group which includes several University of Notre Dame faculty and graduate students, has recently published a paper detailing new work on the analysis and dating of human bruises. The research, which is funded by the Gerber Foundation, will have particular application to pediatric medicine, as bruise age is often key evidence in child abuse cases.
LA JOLLA, CA -- A team led by scientists at The Scripps Research Institute has discovered key elements of a strategy commonly used by tumor cells to survive when they spread to distant organs. The finding could lead to drugs that could inhibit this metastasis in patients with tumors.
CORAL GABLES, FL. -- The key to understanding how future hurricanes and sea level rise may trigger changes to South Florida's native coastal forests lurks below the surface, according to a new model linking coastal forests to groundwater. Just inland from the familiar mangroves that line the coasts lie hardwood hammocks that are sensitive to salinity changes in water found in the soils.
Bethesda, Md. -- Women have long bemoaned the fact that as they have more children, their weight gain from pregnancy becomes more difficult to lose. A new study using a mouse model that mimics the human effects of multiparity (giving birth more than once) has found that mouse moms who gave birth four times accrued significantly more fat compared to primiparous females (those giving birth once) of similar age. The study also found significantly more inflammation in the livers of multiparous animals.
Dr. François Robert, molecular biology researcher at the Institut de recherches cliniques de Montréal (IRCM), and his team confirmed that the phosphorylation of RNA polymerase II, a key enzyme in the process of gene expression, is uniform across all genes. This discovery, which contributes to numerous debates on the topic within the scientific community, will be published tomorrow in the scientific journal Molecular Cell.
Los Angeles, CA - Distrust and paranoia about government has a long history, and the feeling that there is a conspiracy of elites can lead to suspicion for authorities and the claims they make. For some, the attraction of conspiracy theories is so strong that it leads them to endorse entirely contradictory beliefs, according to a study in the current Social Psychological and Personality Science (published by SAGE).
While residents of the United States and much of Europe think of locust plagues as biblical references, locust swarms still have devastating effects on agriculture today, especially in developing countries in Asia and Africa.
In a study in the journal Science on Jan. 27, scientists from Arizona State University and the Chinese Academy of Sciences show that insect nutrition and agricultural land management practices may partially explain modern day locust outbreaks.
Ecologists are still arguing about the nature of the factors that determine the species composition of ecological communities. On the one hand, there are those who view interspecies competition as the key element. A second group of influential ecologists postulates that random fluctuations in population structure and rates of species dispersal play the dominant role, particularly in the biological communities found in species-rich tropical rainforests. LMU biologist Professor Susanne Renner, who is Director of the Botanic Garden and herbaria in Munich, and Professor Robert E.
Irvine, Calif., Jan. 26, 2012 – Location matters for birds on the hunt for caterpillars, according to researchers at UC Irvine and Wesleyan University. Findings suggest that chickadees and others zero in on the type of tree as much as the characteristics of their wriggly prey.
(SACRAMENTO, Calif.) -- Patients with head and neck cancers who have been treated with newer, more sophisticated radiation therapy technology enjoy a better quality of life than those treated with older radiation therapy equipment, a study by UC Davis researchers has found.
WASHINGTON, DC – Research physicians from Georgetown Lombardi Comprehensive Cancer Center will present new data about a complex group of cancers known as head and neck cancers at the Multidisciplinary Head and Neck Cancer Symposium, January 26 through 28, in Phoenix, Arizona.
Should patients with HPV+ head and neck cancers receive less chemotherapy?
Georgetown researchers are examining a hypothesis about whether HPV+ patients with a head and neck cancer should receive more or less chemotherapy.
