New genetic understanding of progressive hearing loss

In parallel studies in human and mouse, two groups of researchers have come to the same conclusion: that a new kind of gene is associated with progressive hearing loss.

New type of probe enables visualization of single ribonucleic acid

Biomedical engineers have developed a new type of probe that allows them to visualize single ribonucleic acid (RNA) molecules within live cells more easily than existing methods.

New cancer genomics web-based tools provide researchers a powerful new to visualize and analyze data

A Cancer Genomics Browser developed by researchers at the University of California, Santa Cruz, provides a new way to visualize and analyze data from studies aimed at improving cancer treatment by unraveling the complex genetic roots of the disease.

Discovery of major new risk factor for melanoma in young women

Researchers may have found a more potent risk factor for melanoma than blistering sunburns, freckling, or family history of the deadly skin disease.

Rewrite of the recipe for life - new type of DNA

In a dramatic rewrite of the recipe for life, scientists from Florida today described the design of a new type of DNA with 12 chemical letters instead of the usual four.

Scientists make a new protein from scratch

No doubt proteins are complex. Most are "large" and full of interdependent branches, pockets and bends in their final folded structure.

Understanding mental illness through gene-environment interactions

Biological Psychiatry, published by Elsevier, is very pleased to present a special section of its February 1st issue devoted to fundamental new insights into epigenetics, a field of research devoted to understanding how the environment can produce long-lasting or even heritable changes in gene function without altering the DNA sequence.

New tumor markers determine therapy intensity

Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are.

One virus particle is enough to cause infectious disease

Can exposure to a single virus particle lead to infection or disease? Until now, solid proof has been lacking. Experimental research with insect larvae at Wageningen University and Simon Fraser University in Canada has shown that one virus particle is theoretically enough to cause infection and subsequent disease.

Measuring the strength needed to move chromosomes

It's about as long as the width of a human hair and only half that length across. So it's tiny - measured in millionths of a meter - and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly important a role in separating our chromosomes during cell division that scientists are compelled to try to study it.

RNA World: a new frontier in biomedical research

Research into RNA, a molecule found in every cell of our bodies, could lead to remarkable advances in the treatment of diseases such as cancer and diabetes, a meeting organised by the European Science Foundation was told.

Scientists develop general-purpose method for detecting trace chemicals

Described in an advance, online publication of the journal Nature Biotechnology on February 22, 2009, the team's general method could be adapted for detecting a wide variety of compounds, including many that are relevant to diagnostic medicine and environmental work.

New statistical model could predict an individual's lifetime risk of stroke

Using genetic information from 569 hospital patients, the researchers showed that their predictive model could estimate an individual's overall risk of cardioembolic stroke -- the most common form of stroke -- with 86 percent accuracy. The findings are reported in the March issue of Stroke.

Calculating protein and gene connections in a Parkinson's model

Researchers have created an algorithm that meshes existing data to produce a clearer step-by-step flow chart of how cells respond to stimuli.

Optimizing dosage of blood-thinning drug warfarin

In a large-scale study and an upcoming clinical trial, scientists supported by the National Institutes of Health address one of the trickiest issues in prescribing medicine - how to quickly optimize each patient's dosage of the common blood-thinning drug warfarin.
