University of Kentucky physician revolutionizes gene research

A dramatic new study published in the most recent issue of Nature questions some of the mechanisms underlying a new class of drugs based on Nobel Prize-winning work designed to fight diseases ranging from macular degeneration to diabetes.

Researchers urge ethics guidelines for human-genome research

A global team of legal, scientific and ethics experts have put forward eight key recommendations to establish much needed guidelines for conducting human-genome sequencing research.

New brain cells implicated in machinery of cannabinoid signaling

The researchers said their findings could aid in development of treatments for cannabinoid drug abuse. Also, because so-called "endocannabinoids" produced by brain cells are involved in the neural machinery of pain perception and learning and memory, the findings could help in understanding those processes, said the researchers.

Key factor in brain development revealed, offers insight into lissencephaly

In the earliest days of brain development, the brain's first cells - neuroepithelial stem cells - divide continuously, producing a population of cells that eventually evolves into the various cells of the fully formed brain.

Insulin-like growth factor found to have new role in development of brain's smell center

A human hormone known to stimulate the growth of cells throughout the body has a new role - helping to set up the proper nerve connections in the odor center of the brain, according to University of California, Berkeley, scientists.

Environmental factors linked to development of autoimmune diseases

Scientists working at the MRC National Institute for Medical Research have shown that environmental factors can influence the development of autoimmune diseases like multiple sclerosis.

The brain can sense the calories in food, independent of taste

Their finding that the brain's reward system is switched on by this “sixth sense” machinery could have implications for understanding the causes of obesity. For example, the findings suggest why high-fructose corn syrup, widely used as a sweetener in foods, might contribute to obesity.

Brain scientist shedding light on learning, memory

Neurons spoke to Dr. Joe Z. Tsien when he was a sophomore college student searching for some meaningful extracurricular activity.

Pectin-rich apple products shown to have anticarcinogenic effects on colon

The apples and apple juice you consume may have positive effects in one of the most unlikely places in the body – in the colon.

Scientists isolate, characterize the organism that causes Buruli ulcer

An international team of 17 researchers from four countries has for the first time isolated from the environment and fully characterized the organism that causes Buruli ulcer.

Next-generation nanomedicine

In an article featured on the cover of the March issue of Nature Nanotechnology, Mauro Ferrari, Ph.D., of The University of Texas Health Science Center at Houston, presented a proof-of-concept study on a new multistage delivery system (MDS) for imaging and therapeutic applications. This discovery could go a long way toward making injectable drugs more effective.

Targeting aggressive breast cancers by putting them to sleep

It is well established that Id1, a gene normally produced only in embryonic development, is reactivated in many 'solid' cancers, or carcinomas.

Spit in a cup to replace needle pricks

One day soon patients may spit in a cup, instead of bracing for a needle prick, when being tested for cancer, heart disease or diabetes.

New understanding of how color vision is processed

New York University biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed.

New method for rapid screening large numbers of antigens

A team of Washington State University scientists has devised a method that could lead to the development of vaccines against some of the most troubling infectious diseases we face diseases that have so far been difficult or impossible to vaccinate against.

A new form of inherited risk of cancer found

Like the subtext of a novel, the human genome sequence harbors more information than appears just in its "letters" of A, C, T and G. Since DNA is a data-packed molecule passed from generation to generation, comparing genome sequences among individuals also holds clues to ancestry.
