Time-reversal acoustics research promises medical breakthroughs

Scientists have not yet found a way to actually make time run backward, but in the cutting-edge world of recent acoustics research, they have shown a way to make sound waves run backward in a kind of ultra-focused reverse echo. By the technology known as time-reversal acoustics, sound waves - in exact reverse order from the original sound - echo directly and very precisely back to their source point.

Completion of the sequencing of human chromosome 19

The United States Department of Energy (DOE) Joint Genome Institute (JGI) and Stanford University report today the completion of the sequencing of human chromosome 19, the most gene-rich of all the human chromosomes. This achievement is described in the April 1, 2004 edition of the journal Nature.

Analysis of Bacterial Genomes Begins to Unravel Complex Story of Metabolic Evolution

In a paper published in the current issue of the journal Molecular Biology and Evolution , Arizona State University biochemists Jason Raymond, Christopher Staples and Robert Blankenship and Rice University's Janet Siefert do an analysis of the genomes of a large group of bacteria and archaea, comparing in particular similar genes that produce the protein nitrogenase.

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules, including a key plague protein whose structure has eluded researchers until now. The technique, developed with support from the National Institute of General Medical Sciences (NIGMS) of the National Institutes of Health (NIH), promises to help pharmaceutical companies develop more effective drugs to treat various diseases by tailor-making molecules to "fit" a protein's shape.

Scientists studying vaccinia virus, a relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation

Scientists at the University of Illinois at Urbana-Champaign studying vaccinia virus, a close relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation, a crucial anti-viral immune response of host cells.

A simple urine sample could soon be used to predict the complex toxic effects of new drugs

BlueGnome has pioneered the use of statistical signal modelling in the analysis of high throughput experimental data. Its first product BlueFuse for Microarrays uses statistical modelling techniques to eliminate Œnoise‚ generated in microarray experiments, enabling researchers to automatically identify the presence or absence of genes and proteins with a higher level of confidence than is currently possible.

Michigan opens new center to treat exposure to Vermiculite, Taconite, Asbestos

In response to the United States Environmental Protection Agency's (EPA) identification of major sources of public asbestos exposure in Michigan, the Barbara Ann Karmanos Cancer Institute and the Center for Occupational and Environmental Medicine (COEM) affiliated with Wayne State University (WSU) have joined forces to establish The National Center for Vermiculite and Asbestos-Related Cancers.

Upcoming symposium to examine mercury exposure

The AMA is co-sponsoring a symposium for CME credit this month in Tampa, Fla., on the medical and public health aspects of mercury exposure. "Mercury: Medical and Public Health Issues" will be held from April 28-30 at the Tampa Marriott Waterside Hotel and Marina.

Mathematicians Predict Patterns in Fingerprints

Patterns in nature can be seen every day, yet in many cases, little is understood about how and why they form. Now University of Arizona mathematicians have found a way to predict natural patterns, including fingerprints and the spirals seen in cacti.

Video consultations to ease stress on frail patients

Monash University's Department of Geriatric Medicine is pioneering a high-tech way of consulting with elderly patients so they do not have to leave their nursing home beds.

New center enables genetic treatments and advances

A new state-of-the-art research facility dedicated to helping produce modified cells for treatment of cancer and other diseases recently opened at the Siteman Cancer Center.

Machine can switch off brain by transmitting harmless magnetic pulses

Professor Snyder's creativity machine was developed at the Centre for the Mind, a joint venture between The Australian National University and the University of Sydney. The machine transmits harmless magnetic pulses through the brain, temporarily switching part of it off, with the potential to reveal an inner genius

Scientists have discovered that a non-genetic molecular process can effect cell behaviour

Genetic mutations, sudden, random and usually harmful changes to the structure of a gene, are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

DakoCytomation has acquired exclusive worldwide rights to develop and commercialize pharmacogenomic diagnostic tests in the field of oncology

Human Genome Sciences, Inc. announced today a license agreement with DakoCytomation A/S (Glostrup, Denmark), under which DakoCytomation has acquired exclusive worldwide rights to develop and commercialize pharmacogenomic diagnostic tests in the field of oncology based on the TRAIL Receptor-1 (TRAIL-R1) and TRAIL Receptor-2 (TRAIL-R2) proteins.

Faster new cloning technique - transcript-based cloning

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function – a painstaking process often requiring years of laboratory trial and error.

Embryonic stem cells attached to a gel matrix instead of suspended in solution

Like many other kinds of cells used in biomedical research, human embryonic stem cells are stored and transported in a cryopreserved state, frozen to -320 degrees Fahrenheit, the temperature of their liquid nitrogen storage bath.

Newly diagnosed non-Hodgkin’s lymphoma linked to monkey virus DNA

Examination of tumors in patients with newly diagnosed non-Hodgkin’s lymphoma found that half of them show evidence of a monkey virus DNA that may have originated from contaminated polio vaccines.

Novel uses for bacterial cellulose, artificial blood vessels, bioengineered wound dressing

New and unique products created from bacterial cellulose — from electronic paper to treatment for wounds — will highlight a one-day symposium at the 227th national meeting of the American Chemical Society, the world's largest scientific society.

Biocompatible adhesives for use with vascular tissue that will speed the process of mending tissue

Surgeons battle time and the body's defenses as they stitch together veins and arteries, whether after an injury or in the course of such treatments as transplants or bypasses. Loss of blood before a site is closed and too much clotting soon after challenge medical care.
