New visualization techniques yield star formation insights
New computer visualization technology developed by the Harvard Initiative in Innovative Computing has helped astrophysicists understand that gravity plays a larger role than previously thought in deep space's vast, star-forming molecular clouds.

Trapped water cause of regular tremors under Vancouver Island: UBC researchers
University of British Columbia researchers are offering the first compelling evidence to explain regular tremors under Vancouver Island.

A rigorous method for liver biopsy
A research group from Italy describes a rigorous method based on the fundamentals of measurement theory, which metrically defines the changes of magnitude of liver tissue prime basic structural elements occurring during the course of B and C chronic hepatitis.

The prevalence of gluten-sensitive enteropathy in iron-deficient anemia patients
A research group from Iran investigated the prevalence of gluten-sensitive enteropathy (GSE) in a large group of patients with iron deficiency anemia (IDA) of obscure origin.

Is bismuth a safe medicine for the treatment peptic ulcer disease?
Researchers in Canada and Germany performed a systematic review and meta-analysis examining adverse events arising from the use of bismuth compounds in Helicobacter pylori (H. pylori) eradication therapy.

Lung cancer cells activate inflammation to induce metastasis
A research team from the University of California, San Diego School of Medicine, has identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells.

Grape-seed extract kills laboratory leukemia cells, proving value of natural compounds
An extract from grape seeds forces laboratory leukemia cells to commit cell suicide, according to researchers from the University of Kentucky.

In lung cancer, silencing one crucial gene disrupts normal functioning of genome
While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism.

What is the pathogenesis of C. jejuni-related disease?
A research group from United Kingdom investigated the mechanisms by which Campylobacter jejuni (C. jejuni ) causes inflammation and diarrhea.

Bright lights, not-so-big pupils
A team of Johns Hopkins neuroscientists has worked out how some newly discovered light sensors in the eye detect light and communicate with the brain.

A new light on the anti-tumor mechanisms of Scutellaria barbata
A research group in China investigated the growth inhibitory and apoptotic effects of Scutellaria barbata D.Don (S. barbata) and determined the underlying mechanism of its anti-tumor activity in mouse liver cancer cell line H22.

Smokers with stroke in the family 6 times more likely to have stroke too
A new study shows that people who are smokers and have a family history of brain aneurysm appear to be significantly more likely to suffer a stroke from a brain aneurysm themselves.

Seizing the day
Tel Aviv University researchers find epileptics in stressful jobs can handle the pressure.

Hubble telescope to get last tuneup during International Year of Astronomy
As the International Year of Astronomy dawns, the renowned Hubble Space Telescope is preparing for its final chapter, starting with the scheduled May 12 launch of the space shuttle Atlantis for NASA's fifth and final service mission to the telescope.

Fewer deaths with preventive antibiotic use
Administering antibiotics as a preventive measure to patients in intensive care units increases their chances of survival.

The culture of medicine
Everybody is familiar with the stereotypes of medical education from the student perspective: grueling hours, little recognition and even less glory.

Why prostate cancer patients fail hormone deprivation therapy
The hormone deprivation therapy that prostate cancer patients often take gives them only a temporary fix, with tumors usually regaining their hold within a couple of years.

Researchers engineer pancreatic cell transplants to evade immune response
In a finding that could significantly influence the way type 1 diabetes is treated, researchers at Albert Einstein College of Medicine of Yeshiva University have developed a technique for transplanting insulin-producing pancreatic cells that causes only a minimal immune response in recipients.
