Alcohol's effects on gene expression in the central nervous system

... despite recent advances, researchers need further developments in microarray technologies and bioinformatic approaches to better understand the complex neurobiological mechanisms underlying alcohol addiction. "Future research will need to determine changes in gene expression in very discrete neuronal pathways th...

New methods of gene delivery using lasers

.... Optical technology has huge potential for novel developments in the bio-medical field and St Andrews has outstanding research groups in this area. The new method -which involves a miniature violet laser -is cheap, simple, powerful and versatile. Its adaptability means it could have potentially wide medical app...

Tsunami-damaged coral reefs should be left to recover naturally, say scientists

...but they would be better advised to set back their developments a little to minimise the impact on sea life. Communities that are rebuilding hotels should take advantage of reconstruction funds to make sure there is effective sewage treatment available. And if builders are moving lots of earth around, they should...

Hopkins AIDS experts issue warning about global efforts to provide drug therapies

...Laura McGough, Ph.D., the team reviewed four major developments in medicine that shared the issues confronting distribution of antiretroviral therapies. The first two pivotal events were advances to treat if not cure then-fatal diseases: the discovery of insulin for diabetes in 1922 and the mass distribution of ...

Marine bacterium suspected to play role in global carbon and nitrogen cycles

...d genome-enabled studies, the MO program funds new developments in the laboratory cultivation of novel microorganisms--a worthy endeavor considering that less than 1 percent of Earth's microorganisms have been cultured in the lab. Matt Kane, NSF program manager for this research said, "This is a great example of...

Naturally occurring asbestos linked to lung cancer

...been a source of increasing concern as new housing developments cut through these areas. Of most concern are the areas of ultramafic rock associated with tremolite asbestos. In their ambitious study, Schenker and his colleagues used California Cancer Registry data to identify 2,908 cases of malignant mesotheliom...

Drugs from the deep blue

...s such as plants or bacteria. Molinski says modern developments in analytical chemistry, including highly sensitive instrumentation, sophisticated screening capabilities and discoveries from mapping the human genome, have created a renaissance of interest in these sources of potential medicines. Molinski's labor...

A step toward the $1,000 personal genome using readily available lab equipment

...bacterial DNA that had evolved in the lab. "These developments give the feeling that improvements are coming very quickly," said HMS professor of genetics Church, who also heads the Lipper Center for Computational Genetics, MIT-Harvard DOE Genomes to Life Center, and the National Institutes of Health (NIH) Cente...

Confronting Influenza: Are We Prepared?

... the 1918 pandemic, current H5N1 (Avian influenza) developments in Asia, the state of U.S. preparedness and influenza surveillance, and the private sector's views on drug development. ...

Researcher says flu responders can learn from 1918 epidemic

...al knowledge, research findings and pharmaceutical developments provide some hope that 21st century Americans might not suffer the fate of their forebears, but Higgins said that survival might depend on the simple concept of community planning. In studying the metropolitan areas around the state of Pennsylvania,...

Science's Breakthrough of the Year: Watching evolution in action

...make up Science 's list of the top ten scientific developments in 2005, chosen for their profound implications for society and the advancement of science. Science 's Top Ten list appears in the 23 December 2005 issue of the journal Science . Many of this year's breakthrough studies followed evolution at the g...

NIH launches comprehensive effort to explore cancer genomics

...ug for one form of breast cancer. These successful developments support further examination of the molecular origins of cancer to more quickly develop new tools to diagnose, treat, and prevent cancer. In the TCGA Pilot Project, a Human Cancer Biospecimen Core Resource will support the collection, processing, a...

Ahead of the game

...dern humans. Instead, the researchers suggest that developments in the social realm of modern human life, allowing routine use of distant resources and more extensive division of labor, may be better indicators of why Neanderthals disappeared than hunting practices. "The establishment of larger social networks a...

New University of Toronto research a 'pore' excuse for engineering

...cted ways, and what we've found here could lead to developments in microelectronics or drug delivery systems." Conventionally, computer chip manufacturers have insulated their wire connections with silica glass, preventing them from coming into contact and interfering, with each other. But the PMO film described...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...tive deterioration in old age. The basis for these developments is Schwartz's team's observations, published today in the February issue of Nature Neuroscience, that immune cells contribute to maintaining the brain's ability to maintain cognitive ability and cell renewal throughout life. Until quite recently, i...

Unraveling the viral mechanism

...eloped a new image reconstruction algorithm. These developments enabled him and his co-authors at MIT to see through the bacteriophage at very high resolution. "It turns out that, in addition to the surface protein, there are other proteins that make this virus viable," said Chiu. In particular, proteins prot...

Life, the remake

... groups. Vermeij said that many of life's "unique" developments might just appear to be so because other species died out and were not preserved as fossils. A "unique" innovation might also be the result of intense natural selection. For example, once the genetic code appeared, primitive organisms readily swappe...
