DURHAM, N.C. -- In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms.
Fifty days after scientists applied a single low dose of silver nanoparticles, the experimental environments produced about a third less biomass in some plants and microbes.
Your risk of dying from a heart attack may increase after your adult sibling dies, according to new research in the Journal of the American Heart Association.
"Death of a family member is so stressful that the resulting coping responses could lead to a heart attack," said Mikael Rostila, Ph.D., lead author of the study and associate professor at Stockholm University/Karolinska Institutet in Stockholm, Sweden. "But our results suggest that this association between the loss of a sibling and having a heart attack is more likely to occur some years after bereavement."
PHILADELPHIA, PA (February 27, 2013)—Two proteins that scientists once thought carried out the same functions are actually antagonists of each other, and keeping them in balance is key to preventing diseases such as cancer, according to new findings published in the February 25 issue of Developmental Cell by scientists at Fox Chase Cancer Center. The results suggest that new compounds could fight cancer by targeting the pathways responsible for maintaining the proper balance between the proteins.
Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have achieved a major advance in understanding how genetic information is transcribed from DNA to RNA by providing the first step-by-step look at the biomolecular machinery that reads the human genome.
(Santa Barbara, Calif. –) Bioengineering researchers at University of California, Santa Barbara have found that changing the shape of chemotherapy drug nanoparticles from spherical to rod-shaped made them up to 10,000 times more effective at specifically targeting and delivering anti-cancer drugs to breast cancer cells.
COLUMBIA, Mo. — Fashion retailers have seen an increase in demand for maternity wear in recent years, as sales for maternity clothing have increased while overall women's apparel sales have declined. Currently, most retailers produce maternity wear using a standardized size chart that begins with women in their seventh month of pregnancy. Retailers produce garments for women who are earlier in their terms by adjusting the sizes smaller proportionally based on the standardized chart.
MAYWOOD, Il. – Loyola University Chicago Stritch School of Medicine researchers have developed a genetically modified protein that dramatically reverses the skin disorder vitiligo in mice, and has similar effects on immune responses in human skin tissue samples.
BOSTON, MA—Scientists from Brigham and Women's Hospital are on the brink of the next treatment advancement that may spell relief for the nearly nineteen million adults and seven million children in the United States suffering from asthma. The scientists discovered two new drug targets in the inflammatory response pathway responsible for asthma attacks.
The study will be published on February 27, 2013 in Science Translational Medicine.
Obesity rates across Canada are reaching alarming levels and continue to climb, according to a new University of British Columbia study.
Published today in the Canadian Journal of Public Health, the study provides the first comprehensive look at adult obesity rates across Canada since 1998, complete with "obesity maps."
Rosemont, Ill. – Patients with diabetes were no more likely to suffer infection, deep vein thrombosis (a deep vein blood clot) or other complications following total knee replacement (TKR) than patients without diabetes, according to new research published online today, in advance of its publication in the March 2013 Journal of Bone and Joint Surgery (JBJS).
Research indicates that half of all lifetime cases of mental illness begin by age 14, well before adulthood. Three new studies investigate the cognitive, genetic and environmental factors that may contribute to mental health disorders in adolescence. The studies are published in Psychological Science and Clinical Psychological Science, journals of the Association for Psychological Science.
STANFORD, Calif. — Hailed as a major step forward in the effort to develop targeted cancer therapies, a recently approved drug for the most common type of skin cancer has been a mixed blessing for patients. Although the initial response is usually dramatic, the tumors often recur as the cancer becomes resistant to treatment.
An extraordinary find allowing scientists to see through the head of the 'fuxianhuiid' arthropod has revealed one of the earliest evolutionary examples of limbs used for feeding, along with the oldest nervous system to stretch beyond the head in fossil record.
Until now, all fossils found of this extremely early soft-bodied animal featured heads covered by a wide shell or 'carapace', obscuring underlying contents from detailed study.
Chronic or acute, liver failure can be deadly. Toxins take over, the skin turns yellow and higher brain function slows.
"There is no effective therapy at the moment to deal with the toxins that build up in your body," said Neil Talbot, a Research Animal Scientist for the USDA Agricultural Research Service. "Their only option now is to transplant a liver."
