Needling Chromosomes Reveals Cell Division Secret

...urrent Biology, Leocadia Paliulis andBruce Nicklas report their progress in understanding how the pairs ofchromosomes in each cell manage to balance their adhesion to oneanother and their release during cell division. Their work wassponsored by the National Institutes of Health. Chromosomes are thetiny fibe...

Scientists discover the cellular roots of graying hair

...ause of this usually unwelcome transformation.In a report posted today on the Web site of the journal Science,researchers from Dana-Farber Cancer Institute and Children’s HospitalBoston say they have found the cellular cause of graying hair whileinvestigating the origins of malignant melanoma, the potential...

Researchers identify target for cancer drugs

...journal Science, researchers from the Sabatini lab report on discovering an important missing piece of the activation process. This missing component, a molecule called mTOR, is a protein that influences a cell's ability to expand in size. mTOR has been widely studied as the target for the immunosuppressan...

U-M scientists find genes that control growth of common skin cancer

... forthe treatment of this widespread disease.Their report will be published in the Jan. 15 issue of Genes &Development, but is available now on the journal's Web site . Basal cell carcinoma (BCC) affects over 1,000,000 Americans each year and frequently develops onsun-exposed sites, such as the face....

Study: Soap And Water Work Best In Ridding Hands Of Disease Viruses

Rutala and David J. Weber, professors of medicine and epidemiology at the UNC schools of medicine and public health; Dr. Mark D...

UCSD researchers maintain stem cells without contaminated animal feeder layers

... clinical applications is timely, given the recent report of 17 newly derived stem cell lines available for non-federal research. The findings here may facilitate the derivation of new human embryonic stem cell lines without the use of animal or human feeder layers." ...

Placenta Is A Rich Source Of Blood Stem Cells

...spital Boston and the Dana-Farber Cancer Institute report a surprising finding about embryonic development: the blood system begins to form not only in the embryo itself, but also in the placenta, the organ that nurtures the baby in utero. Meticulous experiments in mice revealed that the placenta harbors a...

Researchers find missing genes of ancient organism

Yale scientists report in the journal Nature that the "missing" genes for tRNA in an ancient parasite are made up by splicing together sequences in distant parts of the DNA genome. The research led by Professor Dieter Söll in the Department of Molecular Biophysics and Bio...

Scientists identify genetic pathways essential to RNA interference

...which someday may help to fight human disease. The report will appear in the journal Science and is receiving early online release on the Science Express website at http://www.sciencexpress.org. "The gene activation produced by RNAi is exquisitely specific, which gives it enormous potential for therapeutic...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...sor of physiology at Humboldt University, Germany, report their findings in the Feb. 3 issue of Nature. The insect respiratory system is designed to accommodate occasions when the insect is active. For example, a grasshopper is most active when it flies. When the grasshopper is inactive and resting, howeve...

Scientists document complex genomic events leading to the birth of new genes

...tist at the European Molecular Biology Laboratory, report today in the journal Genome Research that they have identified a new primate-specific gene family that spans about 10% of human chromosome 2. Comprised of eight family members, the RGP gene cluster may help to explain what sets apart humans and other...

Antibodies from plants protect against anthrax

...that could be used to treat anthrax exposure. They report their findings today at the 2005 American Society for Microbiology Biodefense Research Meeting. "The nature of bioterrorism is such that an aggressor is likely to strike at a time and place calculated to induce maximum terror through mass casualties...

Influenza vaccine uses insect cells to speed development

...an experimental cell-based influenza vaccine. They report their findings today at the 2005 American Society for Microbiology Biodefense Research Meeting. "The bird flu may become the next flu pandemic strain. It could happen at any time," says Keyang Wang, a scientist at Protein Sciences Corp. and a resear...

Boosting HIV screening can increase survival and is cost effective

...le, Harvard and the Massachusetts General Hospital report in the February 10 issue of the New England Journal of Medicine (NEJM). The study's findings are part of a two-paper series in NEJM on the value of expanded HIV screening in the United States. The Yale/Harvard study used different data and methods t...
