Subconscious change of heart could happen in response to failure in a competitive situation

You may think of your love for your mate as the noble emotion of a pure heart, but some primitive parts of your brain are taking a decidedly more pragmatic approach to the subject, according to Stanford biologists.

Immunity-enhancing probiotics may be the best line of defense for good health

Good bacteria, bad bacteria, billions of bacteria—sounds downright germy. But the truth is that research in gut health is germinating more insight into the role bacteria, also known as "probiotics," play in our overall health and wellness.

Researchers explain molecular mechanism that induces HER2+ tumours to ignore cell signals

About 30% of breast cancer patients have tumours that show rapid growth and invasion through the body. A common denominator in all of these cases is the presence of a large number of Her2 proteins in tumour cellular membranes. Consequently, these aggressive tumours are referred to as HER2+. Scientists working in the Metastasis Laboratory (MetLab) at IRB Barcelona headed by ICREA researcher Roger Gomis, have described the molecular mechanism that induces HER2+ tumours to ignore the signals that protect cells from excessive growth.

Collective efforts in transplantation reduces risk of treatment-related complications in blood cancer

A decade of refinements in marrow and stem cell transplantation to treat blood cancers significantly reduced the risk of treatment-related complications and death, according to an institutional self-analysis of transplant-patient outcomes conducted at Fred Hutchinson Cancer Research Center.

Research finds ways to tackle drug resistance in melanoma

The past year has brought to light both the promise and the frustration of developing new drugs to treat melanoma, the most deadly form of skin cancer. Early clinical tests of a candidate drug aimed at a crucial cancer-causing gene revealed impressive results in patients whose cancers resisted all currently available treatments.

Dendritic cell vaccine induces immune responses in patients

A new process for creating a personalized vaccine may become a crucial tool in helping patients with colorectal cancer develop an immune response against their own tumors. This dendritic cell (DC) vaccine, developed at Dartmouth and described in a research paper published this week in the journal Clinical Cancer Research, was used after surgical resection of metastatic tumors to try to prevent the growth of additional metastases.

How HIV kills CD4 T cells

Researchers appear to have an explanation for a longstanding question in HIV biology: how it is that the virus kills so many CD4 T cells, despite the fact that most of them appear to be "bystander" cells that are themselves not productively infected. That loss of CD4 T cells marks the progression from HIV infection to full-blown AIDS, explain the researchers who report their findings in studies of human tonsils and spleens in the November 24th issue of Cell, a Cell Press publication.

Chronic jet lag alters brain's intricate role in memory processing

Chronic jet lag alters the brain in ways that cause memory and learning problems long after one's return to a regular 24-hour schedule, according to research by University of California, Berkeley, psychologists.

Mercury from dental fillings exceeds Reference Exposure Level: Report

A new risk assessment report submitted by the International Academy of Oral Medicine and Toxicology this month to the U.S. Food and Drug Administration (FDA) warns that mercury from dental fillings is estimated to cause 67.2 million Americans to exceed the Reference Exposure Level (REL) of 0.3 ug/m3 established by the U.S. Environmental Protection Agency (U.S. EPA) in 1995.

Cannabis compounds trigger immune cells that promote cancer growth

An international team of immunologists studying the effects of cannabis have discovered how smoking marijuana can trigger a suppression of the body's immune functions. The research, published in the European Journal of Immunology, reveals why cannabis users are more susceptible to certain types of cancers and infections.

Embryonic stem cell research has not made good on taxpayer investment

In 2004 Robert Klein, chairman of the California Institute of Regenerative Medicine (CIRM), helped pass Proposition 71, establishing the CIRM with a state taxpayer-funded $3 billion budget for ten years. The measure was passed with promises of affordable cures for virtually all diseases, cures specifically from embryonic stem cells and cloning, as well as tremendous financial payback for the citizens of California. The Los Angeles Times recently noted that Klein plans to seek up to $3 billion more from state taxpayers for his stem cell fiefdom.

Tension-dependent stabilization helps chromosome separation machinery

Scientists have discovered an amazingly simple way that cells stabilize their machinery for forcing apart chromosomes. Their findings are reported Nov. 25 in Nature.

Brain sees same face as male or female depending on field of view

Neuroscientists at MIT and Harvard have made the surprising discovery that the brain sees some faces as male when they appear in one area of a person's field of view, but female when they appear in a different location.

Response to PLX4032 drug short lived in BRAF-mutated metastatic melanoma patients

Researchers with UCLA's Jonsson Comprehensive Cancer Center have found that melanoma patients whose cancers are caused by mutation of the BRAF gene become resistant to a promising targeted treatment through another genetic mutation or the overexpression of a cell surface protein, both driving survival of the cancer and accounting for relapse.

Scientists reveal long-standing mystery about HIV infection

Scientists at Gladstone Institute of Virology and Immunology have solved a long-standing mystery about HIV infection-namely how HIV promotes the death of CD4 T cells.

Researchers discover cells’ response to sour tastes

This Thanksgiving, when you bite into the cranberry sauce and the tartness smacks your tongue as hard as that snide comment from your sister, consider the power of sour. Neurobiology researchers at the University of Southern California have made a surprising discovery about how some cells respond to sour tastes.

Chronic high fat cholesterol diet may lead to Alzheimer's disease

Research from the Laboratory of Psychiatry and Experimental Alzheimers Research at the Medical University Innsbruck (Austria) demonstrated that chronic high fat cholesterol diet in rats exhibited pathologies similar to Alzheimer's disease. The results were published in Molecular Cellular Neuroscience with lead author Dr. Christian Humpel. The study was co-authored by PhD students, Celine Ullrich and Michael Pirchl, from the same Laboratory.

Discovery may lead to new generation of drugs to minimize heart attack risk

An international team led by researchers from the Universities of Leicester and Cambridge has announced a breakthrough in identifying people at risk of developing potentially fatal blood clots that can lead to heart attack.

Diabetes drug may counteract against Alzheimer's disease: Research

Metformin, a drug used in type 2-diabetes might have the potential to also act against Alzheimer's disease. This has been shown in a study from scientists of the German Center for Neurodegenerative Diseases (DZNE), the University of Dundee and the Max-Planck-Institute for Molecular Genetics.
