Evidence now suggests eating soy foods in puberty protects against breast cancer

Evidence is growing from animal and human studies that genistein, a potent chemical found in soy, protects against development of breast cancer - but only if consumed during puberty, says a Georgetown University Medical Center researcher in the British Journal of Cancer published online today. The challenge now, she says, is for scientists to understand precisely why soy appears to provide a shield against the most common cancer in women.

Carbon nanotubes made into conductive, flexible 'stained glass'

Carbon nanotubes are promising materials for many high-technology applications due to their exceptional mechanical, thermal, chemical, optical and electrical properties.

Now researchers at Northwestern University have used metallic nanotubes to make thin films that are semitransparent, highly conductive, flexible and come in a variety of colors, with an appearance similar to stained glass. These results, published online in the journal Nano Letters, could lead to improved high-tech products such as flat-panel displays and solar cells.

The habits and roles of blog readers

In a first-of-its-kind study, UC Irvine researchers have provided new insight into blog readers’ online habits and experiences, as well as how they perceive their roles in blog-based communities.

Wellmune WGP supplementation alleviates

SAN DIEGO, CA. — April 9, 2008 — Wellmune WGP®, a natural immune-enhancing ingredient from Biothera, reduced the incidence of fever and eliminated the need for study subjects to miss work or school due to the cold-like symptoms, researchers reported today at the 2008 Experimental Biology annual meeting.

Negligent, attentive mouse mothers show biological differences

MADISON - In mice, child neglect is a product of both nature and nurture, according to a new study.

Video doc helps HIV-positive patients reduce risky behaviors

A computer-based interactive risk assessment and risk reduction counseling program using a video doctor sharply reduces sexual and drug risk behaviors by HIV-positive patients, according to UCSF researchers who developed and tested the intervention.

At home on a crab, with new evolutionary neighbors

The members of Drosophilidae, a family consisting of about 3000 species, are often referred to as fruit flies although most of the members feed on microbes. As microbes can be found growing on a wide range of substrates, fruit flies can accordingly also be found in a multitude of habitats.

Diabetes drug may hold potential as treatment for epilepsy

Metformine, a widely used diabetic drug, might also be an effective and safe therapy for epilepsy, researchers report. This new approach may be especially helpful for the subset of patients who have recurrent seizures despite therapy with the best available drugs.

Stopping a cancer trial early: is it for the benefit of patients or industry?

New research has identified a growing trend for trials of new cancer treatments to be stopped prematurely before the therapies’ risks and benefits have been properly evaluated.

Hepatitis B virus triggers cell 'suicide' in patients with chronic infection

Scientists from UCL (University College London) have identified a key difference between people who can fight the Hepatitis B virus (HBV) off successfully and those who fail to do so – that a group of cells important in controlling the disease are triggered to ‘commit suicide’ in patients who are chronically infected. This discovery provides an important new focus for developing therapies or vaccines that boost the body’s ability to manage this infection.
