Research on Worms Yields Clues on Aging

...ndings are reported in the January 14 issue of the journal Science. Theanti-aging effect was revealed in a random screening of 19 drugsapproved for treating a variety of disorders in humans. "We didn'tstart with a hypothesis about what causes aging," says senior authorKerry Kornfeld, M.D., Ph.D., associate ...

Iron Deficiency Sparks Dramatic Changes In Gene Expression

...h, arepublished in the Jan. 14, 2005, issue of the journal Cell. Iron deficiency is the most prevalent and severe nutritional disorderworld wide, affecting more than 2 billion people. The most widelyrecognized symptom is anemia, in which too few red blood cells areproduced, and the body is deprived of oxyge...

Found: Missing sequence of the human Y chromosome

Scientists report today in the journal GenomeResearch that they have successfully cloned and characterized apreviously intractable DNA sequence: a 554-kilobase-pair genomicsegment near the centromere of the human Y chromosome. This sequencecontains eight putatively active genes that could...

Researchers reveal the infectious impact of salmon farms on wild salmon

...e March 30th edition of the prestigious scientific journal Proceedings of the Royal Society B (a publication of the UK's national academy of science) shows that the transfer of parasitic sea lice from salmon farms to wild salmon populations is much larger and more extensive than previously believed. This qu...

Molecular machine may lead to new drugs to combat human diseases

...ue study are published in the January issue of the journal Nature Structural and Molecular Biology. "In terms of human health, Group I introns are interesting because they cause their own removal and also splice the ends of the surrounding RNA together, forming a functional gene," Golden said. "We can desi...

Color-blind method opens new doors in DNA sequencing

In the paper, Metzker, Rice University Professor Robert Curl and colleagues from BCM and Rice describe a new way of doing DNA sequencing that could be more accurate than current methods. DNA in the nu...

Mouse brain tumors mimic those in human genetic disorder

... will be published in the January 2005issue of the journal Annals of Neurology.NF1 is one of the most common neurological disorders caused by a singlegene mutation. The disorder can lead to a variety of complicationsincluding brain cancer.To supplement their clinical research, Gutmann's team developed a mous...

New Clues Add 40,000 Years to Age of Human Species

... report their findings in the Feb. 17 issue of the journal Nature. The fossils, from near the town of Kibish, are far more ancient than researchers originally suspected and nearly 40,000 years older than skulls from Herto, Ethiopia, the previous record holders. The Kibish hominids—dubbed Omo I and Omo II—w...

A bacterial genome reveals new targets to combat infectious disease

...new study published in the freely-available online journal PLoS Biology, Barton Slatko and colleagues present the complete DNA sequence of the Wolbachia pipientis strain within Brugia malayi, a parasitic nematode responsible for lymphatic filariasis. This Wolbachia genome is small, only about a million base...

BRCA1 causes ovarian cancer through indirect, biochemical route

...rk is being published in the March 29 issue of the journal Current Biology. "Before, we thought this gene was a classical tumor suppressor," says Louis Dubeau, professor of pathology at the Keck School and principal investigator on the paper. If that were the case, it would mean that mutation of the gene wo...
