Implantable chip could serve as a prosthetic retina for people who suffer from age-related blindness

Where other types of chips use electricity to stimulate nerves, this one instead tickles cells with minute amounts of chemicals. Because nerve cells normally communicate with each other by releasing chemicals known as neurotransmitters, the new device points to a more effective way of treating very delicate tissues, such as those in the eye and in the brain.

Stimulation or drugs that target the pro-opiomelanocortin system will be effective in treating diabetes or obesity

There’s more than one way to slim a cat - at least that’s the hope of University of Florida obesity researchers, who believe pets and even people may someday benefit from gene therapy research aimed at breaking through the biochemical bottleneck that makes many middle-aged mammals gain weight.

A natural molecule that blocks a key bacterial enzymes could lead to a new generation of antibiotics

Rutgers scientists have deciphered the complex mechanics of microcin J25 (MccJ25), a tiny, natural molecule that acts like a cork in a bottle to block a key bacterial enzyme – potentially leading to a new generation of antibiotics.

Oxidants are responsible for sex in algae

Colonies of the multicellular green alga Volvox carteri exposed to temperatures of 111 degrees Fahrenheit (42.5 degrees Celsius) had twice the amount of free radicals, oxidants that can damage biological structures, as unheated colonies. High levels of oxidants within their cells activated the algae's sex-inducer gene, the researchers report.

Computational design used to engineer and construct a protein that could sense the nerve agent soman

Duke University Medical Center biochemists have used computational design to engineer and construct a protein that could sense the nerve agent soman. They said their achievement constitutes a proof-of principle that such engineered proteins can be made to detect nerve agents such as sarin and other toxic substances.

Neuroscientists have overcome a major obstacle in gene therapy research

Northwestern University neuroscientists have overcome a major obstacle in gene therapy research. They've devised a method that will safely deliver and regulate expression of therapeutic genes introduced into the central nervous system to treat Parkinson's disease and other neurodegenerative diseases.

3-D micro-imaging technology licensed to Carl Zeiss Jena by Cornell

Biomedical microscopic imaging deep inside living tissue with unprecedented clarity could become routine and widely available with the signing of technology-transfer and collaborative-research agreements today (May 28, 2004) by Carl Zeiss Jena GmbH, a leading maker of microscopy instrumentation, and by CCTEC, the technology, enterprise and commercialization arm of Cornell University.

Randomness in gene expression to lead to differences in people that are genetically identical

Experiments by Howard Hughes Medical Institute (HHMI) researchers have revealed it might be possible for randomness in gene expression to lead to differences in cells — or people, for that matter — that are genetically identical.

Evidence that abnormally short telomeres play a role in the early development of cancer

Scientists at the Johns Hopkins Kimmel Cancer Center say they have evidence that abnormally short telomeres - the end-caps on chromosomes that normally preserve genetic integrity -appear to play a role in the early development of many types of cancer.

Researchers to develop a highly sensitive, portable method of detecting bioterror agents like anthrax

Their method uses "Cellular Analysis and Notification of Antigen Risks and Yields" (CANARY) cells, which are immune-system cells engineered to contain a fluorescent protein naturally found in jellyfish. CANARY cells have the immune system's ability to detect specific disease-causing agents, lighting up when they recognize a pathogen.

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals. The discovery was made by applying the latest laboratory methods to a strain of mice restored from embryos frozen since the early 70s.

New study of tumor genetics may help to treat patients with head and neck cancer

Head and neck tumors account for more than 40,000 new cancers annually in the United States. The most common of these is squamous cell carcinoma. Prognosis is based largely on location and size of the tumor, and if the cancer has spread, or metastasized, to lymph nodes and distant sites in the body.

Scientists may have figured out how to use stem cells to regenerate lost or injured tissue

In experiments with fruit flies, Johns Hopkins scientists have restored the insect's sperm-making stem cells by triggering cells on the way to becoming sperm to reverse course. The unexpected findings are described in the May 13 issue of Science.

Scientists have identified a compound that halts the activity of a deadly toxin called anthrax

University of Chicago scientists have identified a compound that halts the activity of a deadly toxin called anthrax lethal factor in laboratory tests. Nature Biotechnology will publish the findings online on May 16 and in the June issue of the journal's print edition.

Technique to visualize changes in nerve connections when flies learn may help to understand how memories form

For the first time, researchers have used a technique called optical imaging to visualize changes in nerve connections when flies learn. These changes may be the beginning of a complex chain of events that leads to formation of lasting memories.

Protein identification gets a speed boost

But the labor intensity of the procedure is now a thing of the past for researchers in the Oregon Health & Science University School of Medicine. The Proteomics Shared Resource, an unassuming but state-of-the-art lab on the fifth floor of OHSU's Medical Research Building, can process more than three times as many protein samples in half a day, and much of it can be done by one person.
