Searching for eco-friendly, "natural" biological control strategies, scientists at Jawaharlal Nehru University in New Delhi have identified the potent killer protein created by an insecticidal bacterium that lives symbiotically with an "entomopathogenic" nematode.
Autophagy means "self-eating." Cells use it to survive starvation and to recycle proteins but work by Japanese researchers at the National Institute of Genetics show autophagy in a new role as the cell's innate 'second line of defense' against invading pathogens such as strep. bacteria.
A "pdf" version of "Cell Biology 2004," the press book for the ASCB Annual Meeting, Dec. 4-8, is now accessible to registered science journalists. Registration is free, carries no obligation to attend, and is thus one heck of a deal.
The American Society for Cell Biology, with 11,000 scientist members working in basic biomedical research in the US and 50 countries around the world, opposes any United Nations action to prohibit stem cell research with the potential to understand and treat disease.
The American Society for Cell Biology has opened its "Free Online "˜Working Press' Registration" at www.ascb.org for science journalists interested in covering its 44th Annual Meeting.
Yale's Tom Pollard,the cell biologist whose research group discovered the long-sought mechanism by which eukaryotic cells move and change shape, is the 2004 winner of the E.B. Wilson Medal, the highest scientific honor of the American Society for Cell Biology.
Two scientists whose research discoveries changed the ground rules in their respective fields were named winners today of the 2004 "Women In Cell Biology Senior and Junior Career Awards" by the American Society for Cell Biology.
The ASCB is protesting the Bush administration's "Friday Afternoon Massacre," the removal of Elizabeth Blackburn, renowned biologist and former ASCB president from the President's Bioethics panel, saying the firing significantly undermines the Council scientific credibility.
Harvey Lodish, president of the American Society for Cell Biology and an Ohio native son, calls on Governor Taft and the Ohio Board of Education to reject the latest attempt by Creationists to undermine Ohio science education.
ASCB names"Hot Picks," top research papers in Late Abstracts presentions at Annual Meeting. Papers cover range of topics from the origins of Gullah-speaking African-Americans to a powerful cellular self-defense mechanism against breast cancer.
At the Annual Meeting: Cell biologists at UC Davis show for the first time that mesenchymal stem cells can be dehydrated for storage and activated for possible use in future stem cell therapies.
At the Meeting"”A simple worm with exactly 302 neurons may serve as a laboratory model for epileptic seizures in the vastly more complex human brain, say University of Alabama cell biologists.
At the meeting"” A new discovery about neuronal transport in mice may clarify a rare but devastating progressive neuromuscular disease in humans, according to University of Pennsylvania cell biologists.
At the Meeting: Johns Hopkins researchers demonstrate that a simple mechanical cue"”growing room"”can influence the fate of mesenchymal stem cells.
At the ASCB meeting"”The human genome is kept safe inside the cell nucleus behind gates called nuclear pore complexes. UC San Diego researchers have now identified the "linchpins" that hold these critical gates together.
At the meeting: The fast and furious "sonic" muscle of the male midshipman fish gives NIAMS researchers a possible clue to a human muscle-weakening genetic disease.
At the meeting: Harvard biologist shows video of a never-before-witnessed sight"”the transport and fusion of a single influenza virus inside a living cell.
At the meeting: European "Bionic Ear" researchers report isolation of stem cells from vestibular sensory epithelia (VSE) that can be manipulated into becoming new sensory hair-cells.
Researchers trace human sex reversal"”genetic XY males born with female reproductive organs or genitalia"”to a misshapen protein that cannot enter the cell nucleus.
Cells exposed briefly to soluble metal ions, specifically chromium or vanadium, can become chromosomally damaged, resulting in long-term genomic instability.
Weeks after the initial injury, the formation of fibrotic or scar tissue in muscle can prevent total recovery, say researchers, but the key to healing without scarring may be in controlling an overlooked transforming growth factor.
"Cell Biology 2003," the essential press guide for the American Society for Cell Biology's Annual Meeting, Dec. 13-17, 2003, in San Francisco, is now available at no charge to science journalists.
The world's largest society of cell biology researchers released a statement today opposing a proposed United Nations ban on cloning research as overbroad and likely to damage biomedical progress against human disease.
