Is some homophobia self-phobia?
Homophobia is more pronounced in individuals with an unacknowledged attraction to the same sex and who grew up with authoritarian parents who forbade such desires, a series of psychology studies demonstrates.

Scientists identify major source of cells' defense against oxidative stress
New research from USC on a protein that protects cancer and other cells from oxidative stresses could one day help doctors to break down cancer cells' defenses, making them more susceptible to treatment.

Coordinating the circadian clock: Molecular pair controls time-keeping and fat metabolism
Disruption in circadian rhythms leads to increased incidence of many diseases, including cancer.

UK company to demonstrate their commercially effective graphene production process
The UK company Haydale will be demonstrating their patented plasma-based technology that enables the scalable production of graphene nano platelets from powdered graphite.

Neng Chen, PhD is the recipient of the 2012 Richard King Trainee Award.

Researchers use game to change how scientists study disease outbreaks
An international team of scientists--including researchers who teach an annual clinic at the African Institute for Mathematical Sciences in Muizenberg, South Africa -- is helping epidemiologists improve the mathematical models they use to study outbreaks of diseases like cholera, AIDS and malaria.

Innovation Generation
In INNOVATION GENERATION: How to Produce Creative and Useful Scientific Ideas, internationally renowned physician and scientist Roberta Ness bestows all the tools readers need to think

Impact of warming climate doesn't always translate to streamflow
An analysis of 35 headwater basins in the United States and Canada found that the impact of warmer air temperatures on streamflow rates was less than expected in many locations, suggesting that some ecosystems may be resilient to certain aspects of climate change.

Invasive heart test being dramatically overused, Stanford study shows
An invasive heart test used routinely to measure heart function is being dramatically overused, especially among patients who recently underwent similar, more effective tests, according to a new study from the Stanford University School of Medicine.

Pulse pressure elevation could presage cerebrovascular disease in Alzheimer's patients
Researchers at the University of California, San Diego and Veterans Affairs San Diego Healthcare System have shown that elevated pulse pressure may increase the risk of cerebrovascular disease in older adults with Alzheimer's disease.

Predictors identified for rehospitalization among post-acute stroke patients
Stroke patients receiving in-patient rehabilitation are more likely to land back in the hospital within three months if they are functioning poorly, show signs of depression and lack social support according to researchers at the University of Texas Medical Branch (UTMB) at Galveston.

Scientists forecast forest carbon loss
For more than 30 years, scientists at the Harvard Forest have scaled towers into the forest canopy and measured the trunks of trees to track how much carbon is stored or lost from the woods each year.

Long-term studies detect effects of disappearing snow and ice
Regions of the earth where water is frozen for at least a month each year are shrinking as a result of global warming.

Long-term research reveals causes and consequences of environmental change
As global temperatures rise, the most threatened ecosystems are those that depend on a season of snow and ice, scientists from the nation's Long Term Ecological Research Network say.

Long-term neuropsychological impairment is common in acute lung injury survivors
Cognitive and psychiatric impairments are common among long-term survivors of acute lung injury, and these impairments can be assessed using a telephone-based test battery, according to a new study.
