Mutant Gene Shatters Nerves: Was Abe Lincoln Affected?
If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke. The discovery may provide a new explanation for spinocerebellar ataxia type 5 (SCA5) -- a disease previously tied to a human version of the gene and identified in 11 generations of U.S. President Abraham Lincoln's family, starting with his paternal grandparents. SCA5 may have afflicted Lincoln himself. The new study suggests how. Surprising New Role For Proteins In Sister Chromatid Cohesion
Scientists reveal a surprising new role for tDNAs and RNA polymerase III-associated proteins in sister chromatid cohesion. Sister chromatid cohesion (the binding together of the two identical copies of each chromosome that are formed during replication) helps to ensure that chromosomes are accurately segregated during the anaphase of the cell cycle. Sister chromatid cohesion is mediated by a multi-subunit protein complex called cohesin. Inside the cell nucleus, cohesin localizes to centromeres (the point of attachment of sister chromatids) as well as heterochromatin (condensed and genetically inactive regions of DNA). New Risk Marker For Overweight Children Isolated
A study of 40 overweight children has revealed they all share something in common aside from being heavy: each one of them has high levels of apoB48, a structural protein found in intestinal cholesterol. Inexpensive, Mass-produced Genes At Core Of Synthetic Biology Advances
Devices the size of a pager now have greater capabilities than computers that once occupied an entire room. Similar advances are being made in the emerging field of synthetic biology at the University of Houston, now allowing researchers to inexpensively program the chemical synthesis of entire genes on a single microchip. Utah Rep's New Assault on Gaming
Dropping his attempt to outlaw selling violent games to minors, a Utah Representative throws his support behind other states' efforts to ban such sales. In Game|Life. Childhood Cancer Survivors At Increased Risk Of Sarcoma
Survivors of childhood cancers have a ninefold increased risk of developing a secondary sarcoma -- a cancer of connective or supportive tissue such as bone, fat, or muscle -- compared with the general population, according to a study in the February 21 Journal of the National Cancer Institute.

Experiments on moss grown aboard two Space Shuttle missions showed the plants didn't behave as scientists expected them to in the near-absence of gravity. The common roof moss (Ceratodon purpureus) grew in striking, clockwise spirals, according to Fred Sack. He is the study's lead investigator and professor of plant cellular and molecular biology at Ohio State University, Columbus, Ohio.

The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... For Treating Malaria, Less Drugs May Be Best Drugs
The current dosage of drugs used in treating malaria may be helping the parasites become resistant to the drugs faster, without improving the long-term outcome in patients. According to evolutionary biologists, studies using mice suggest that the optimal use of the drugs might slow the spread of drug resistance while making the patient just as healthy.
