Withering well can improve fertility

Contrary to a thousand face cream adverts, the secret of fertility might not be eternal youth. Research by the ecologist Dr. Carlos Herrera, a Professor of Research at the Consejo Superior de Investigaciones Científicas in Seville, Spain has shown that the withering action of flowers may have evolved to protect their seeds. His research is published in the October 2010 issue of the Annals of Botany (http://dx.doi.org/10.1093/aob/mcq160).

African-Americans face kidney disease-related disparities according to 2 new studies

1. Among HIV-Infected Kidney Disease Patients, African Americans are More Likely to Develop Kidney Failure and Die Prematurely

Researchers find faster, less-intrusive way to identify transplant recipients' organ rejection

STANFORD, Calif. - A simple, inexpensive blood test could soon help doctors halt organ rejection before it impairs transplanted hearts and kidneys.

Nonstick coating of a protein found in semen reduces HIV infection

A non-stick coating for a substance found in semen dramatically lowers the rate of infection of immune cells by HIV a new study has found.

The new material is a potential ingredient for microbicides designed to reduce transmission of HIV, a team from the University of Rochester Medical Center and the University of California, San Diego reports in a forthcoming issue of the Journal of Biological Chemistry.

Groundwater depletion rate accelerating worldwide

WASHINGTON– In recent decades, the rate at which humans worldwide are pumping dry the vast underground stores of water that billions depend on has more than doubled, say scientists who have conducted an unusual, global assessment of groundwater use.

Molecular 'playbook' for halting heart failure risk factor uncovered

Like a well-crafted football play designed to block the opposing team's offensive drive to the end zone, the body constantly executes complex 'plays' or sequences of events to initiate, or block, different actions or functions.

Scientists at the University of Rochester Medical Center recently discovered a potential molecular playbook for blocking cardiac hypertrophy, the unwanted enlargement of the heart and a well-known precursor of heart failure. Researchers uncovered a specific molecular chain of events that leads to the inhibition of this widespread risk factor.

Imaging study provides new view of multiple sclerosis

Scientists have uncovered an alternative source for some of the damage associated with multiple sclerosis (MS), an incurable neuroinflammatory disorder. The research, published online by Cell Press on September 23rd in the journal Immunity, reveals a direct interaction between immune cells and neurons that plays a significant role in neuronal injury and may respond to therapeutic intervention.

UCLA cancer researchers discover new signaling pathway that controls cell development and cancer

Researchers at UCLA's Jonsson Comprehensive Cancer Center have discovered a new cell signaling pathway that controls cell growth and development, a pathway that, when defective, helps promote the formation of several major forms of human cancer, including lymphoma and leukemia.

The new pathway, part of a global DNA damage response, turns off 136 genes, including some that have are known to cause cancer because, unchecked, they can promote aberrant cell division.

New technique uncovers hidden insecticide resistance

New technique uncovers hidden insecticide resistance

A new technique pioneered at Liverpool School of Tropical Medicine (LSTM) is improving the detection and monitoring of insecticide resistance in field populations of an important malaria-carrying mosquito.

Arctic soil study turns up surprising results

Across the globe, the diversity of plant and animal species generally increases from the North and South Poles towards the Equator but surprisingly that rule isn't true for soil bacteria, according to a new study by Queen's University biology professor Paul Grogan.

"It appears that the rules determining the patterns for plant and animal diversity are different than the rules for bacteria," says Professor Grogan.

Increased attention to women's health research has yielded gains on some important conditions, but progress lags on others

WASHINGTON -- A concerted effort to boost research on women's health over the last two decades has lessened the burden of disease and reduced deaths among women due to cardiovascular disease, breast cancer, and cervical cancer, says a new report from the Institute of Medicine. The effort has yielded less but still significant progress in reducing the effects of depression, HIV/AIDS, and osteoporosis on women, added the committee that wrote the report.

Vitamin C rapidly improves emotional state of acutely hospitalized patients, say LDI researchers

Treatment with vitamin C rapidly improves the emotional state of acutely hospitalized patients, according to a study carried out by researchers at Montreal's Jewish General Hospital (JGH) and the affiliated Lady Davis Institute for Medical Research (LDI).
