Researchers step toward a Creutzfeldt-Jakob disease test

Researchers have shown that a recently developed laboratory method to amplify prions (Protein Misfolding Cyclic Amplification) can be applied to variant CJD (Creutzfeldt-Jakob Disease).

Genetic embryo screening found to be a costly mistake for many women

According to a new study older women whose embryos were screened for defects before being implanted in the womb lessened their chance of a successful pregnancy.

Scientists tackle deadly hospital superbugs

It infiltrates hospitals as microscopic spores. Its defences are so strong it can resist most antibiotics. And it kills three times as many people every year as MRSA. But scientists at The University of Nottingham are amassing an arsenal of weapons in preparation for counter offensive against the most deadly of hospital superbugs.

Discovery of method to identify how cancer evades the immune system

One of the fundamental traits of a tumor - how it avoids the immune system - might become its greatest vulnerability, according to researchers from the University of Southern California. Their findings, demonstrated in human breast and colorectal cancers, indicate that a technique for determining a tumor's "immune signature," could be useful for diagnosing and treating specific cancers.

Understanding the human journey

In the first scientific publication from The Genographic Project, a five-year effort to understand the human journey, we see the first attempts to answer these age-old questions.

Sensing and following motion

Researchers at the University of Pennsylvania have shed new light on how the brain and eye team up to spot an object in motion and follow it, a classic question of human motor control.

RNA molecules can orchestrate gene activity across vast portions of the human genome

Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

Five distinct subtypes of alcoholism identified

Analyses of a national sample of individuals with alcohol dependence (alcoholism) reveal five distinct subtypes of the disease, according to a new study by scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH).

New drug resistance screening method

A growing number of drug-resistant strains of HIV are a threat to the effectiveness of current treatments despite anti-HIV drug cocktails decreasing the number of HIV-related deaths and improving the quality of life for HIV patients.

Link between ciliary signaling and cancer

Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.

Exercise stimulates the production of new brain cells

Exercise has a similar effect to antidepressants on depression. This has been shown by previous research. Now Astrid Bjornebekk at Karolinska Institutet has explained how this can happen: exercise stimulates the production of new brain cells.

Protein ATM prevents DNA damage from persisting through generations

A protein long known to be involved in protecting a cell from genetic damage has been found to play an even more important role in protecting the cell's offspring.

Support for chromosomal theory of cancer found in cancers' development of drug resistance

Thirty-six years into the war on cancer, scientists have not only failed to come up with a cure, but most of the newer drugs suffer from the same problems as those available in the pre-war days: serious toxicity, limited effectiveness and eventual resistance.

New type of mouse embryonic stem cell discovered

Scientists have discovered a new type of mouse embryonic stem cell that is the closest counterpart yet to human embryonic stem (ES) cells, the National Institutes of Health (NIH) have announced.

Scientists discover role of ataxia telangiectasia mutated protein in DNA repair

Scientists from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), National Cancer Institute (NCI), and Integrative Bioinformatics Inc. have made an important discovery about the role of an enzyme called ataxia telangiectasia mutated protein (ATM) in the body's ability to repair damaged DNA.
