For every woman who is a direct target of sexism, there are others who witness the event and are also affected. The actions of one sexist man affect how female bystanders feel and behave towards men in general. Stephenie Chaudoir and Diane Quinn, from the University of Connecticut in the US, publish their work1 on the effects of bystander sexism and group-level reactions to sexism in Springer's journal Sex Roles.

A 3,000-year record from 52 of the world's oldest trees shows that California's western Sierra Nevada was droughty and often fiery from 800 to 1300, according to new research.
Scientists reconstructed the 3,000-year history of fire by dating fire scars on ancient giant sequoia trees, Sequoiadendron giganteum, in the Giant Forest of Sequoia National Park. Individual giant sequoias can live more than 3,000 years.
The UChicago team found that making cells assume a star shape promotes a tense cytoskeleton, which provides structural support for cells, while a flower shape promotes a looser cytoskeleton. "On a flower shape you get the majority of cells turning to fat, and on a star shape you've got the majority of cells turning into bone," said Kris Kilian, a National Institutes of Health Fellow in Mrksich's research group. The UChicago team published its findings in the March 1 Early Edition of the Proceedings of the National Academy of Sciences.

BIRMINGHAM, Ala. – A vaccine designed to prevent cervical cancer also may protect females from post-surgical recurrence of the disease, according to researchers at the University of Alabama at Birmingham (UAB).
A new study shows that the Gardasil vaccine reduces the likelihood of human papillomavirus (HPV)-related disease recurring after teen and adult women already have had surgery to remove cancer or certain pre-cancerous changes, said Warner Huh, M.D., an associate professor in the UAB Division of Gynecologic Oncology and lead presenter on the study.

Boosting the radiation dose given to prostate cancer patients to a level that cut tumor recurrence in half did not increase the severity of side effects reported by patients up to a decade later. The study led by Massachusetts General Hospital (MGH) Cancer Center researchers also found that patients characterized the impact of continuing side effects on their quality of life as considerably less bothersome than would be expected, based on earlier studies. The article appears in the March 17 cancer issue of the Journal of the American Medical Association.
ATLANTA – New chemotherapy agents appear associated with improvements in survival time for patients with metastatic colorectal cancer but at substantial cost.
Young Britons see significantly more on-screen smoking in movies than their US peers, finds research published ahead of print in the journal Tobacco Control.
The UK film classification system, which rates more films as suitable for young people than its US counterpart, is to blame, say the authors.

Those who are most traumatised are twice as likely to develop the condition as those who are least traumatised by their experiences of war, the research suggests.
The authors base their findings on a random sample of just over 2000 Kuwaiti civilians who endured the Iraqi invasion and seven month occupation of their country in 1990, and were aged between 50 and 69 at the time.
Simple, low-cost measures such as wearing a pedometer to inspire walking and spending a few minutes a day meditating can put adolescents on the track toward better health, researchers report.
These types of side-effect-free steps can quickly help lower important numbers like blood pressure, heart rate and even weight, counteracting today's unhealthy, upward trends among young people, said Dr. Vernon Barnes, physiologist at the Medical College of Georgia's Georgia Prevention Institute.
Both new diagnoses and a history of non-melanoma skin cancer appear to have become increasingly common, and the disease affects more individuals than all other cancers combined, according to two reports in the March issue of Archives of Dermatology, one of the JAMA/Archives journals.
In an article published in the March 2010 Archives of Dermatology, researchers report that in the United States, melanoma treatment in late stages of the disease is of significant cost in the population 65 years and older.
