Researchers demonstrated for the first time a link between cell-death-inducing TRAIL's receptor and cancer susceptibility.

Human factors researchers test voting systems for seniors that can improve voting accuracy and speed
Human factors researchers at Florida State University have identified ways to improve electronic voting accuracy among older voters while also shortening waiting time at the polls.

Taxol with avastin produces noteworthy results
Treatment of breast cancer with Taxol and Avastin increased the period patients went without progression of their disease from 5.9 months to 11.8 months.

Copy number variation may stem from replication misstep
Genome rearrangements, resulting in variations in the numbers of copies of genes, occur when the cellular process that copies DNA during cell division stalls and then switches to a different genetic

New plant study reveals a 'deeply hidden' layer of the transcriptome
Cells keep a close watch over the transcriptome -- the totality of all parts of the genome that are expressed in any given cell at any given time.

In largest U.S. Hep C trial, researchers determine weight-based dosing is key to optimal treatment
As reported recently in the journal Hepatology, WIN-R, a multicenter study of over 5,000 patients with hepatitis C virus showed treatment with weight-based REBETOL® (ribavirin, USP) in combination with pegylated interferon alfa-2b achieved significantly higher rates of sustained virologic response and lower relapse rates compared to combination therapy using a flat dose of RBV 800 mg/day.

FOXO factor promotes survival of oxygen-deprived cancer cells
Scientists report that an evolutionarily conserved transcription factor may have both positive and negative effects on the growth of tumors, depending on whether or not the tumor cells have enough oxygen.

New research tools are too complex for easy answers, researchers say
Scientists who study cancer may be prone to drawing simplistic conclusions from the powerful molecular tools now available because they don't appreciate how complex the data is that is being generated, said a team of Georgetown University Medical Center researchers in the January issue of Nature Reviews Cancer.

Study maps life in extreme environments
A team of biologists have developed a model mapping the control circuit governing a whole free living organism.

Housewives are more ecologically aware and recycle more than university students
Research carried out at the University of Granada reveals that housewives are more willing to separate glass from other garbage than students.

Overeating and obesity triggered by lack of BDNF
Neuroscience researchers demonstrate for the first time that brain-derived neurotrophic factor is an essential component of neural circuits which regulate body weight in adult mice and that its expression in two particular brain regions is required to suppress appetite.

Cardiac stem cell therapy closer to reality
The current issue of Cell Transplantation is devoted to the
