Study sheds light on how Down's prevents cancer
January 2, 2008 01:26 PM - Reuters

WASHINGTON (Reuters) - People with Down's syndrome suffer cancer less than most other people and a study in mice published on Wednesday gives one possible explanation -- they produce higher levels of a certain protein. The protein may keep tumors from growing, and this finding may help in the development of new cancer drugs, the team at Johns Hopkins University in Baltimore reported.

Study links ovarian cancer survival to gene change

Ashkenazi Jewish women who had changes in the BRCA1 or BRCA2 genes were 28 percent less likely to die from the disease over a follow-up period of up to nine years during the study even though such mutations increase the chances of developing breast or ovarian cancer in the first place, the researchers said.

Helium Supplies Endangered, Threatening Science And Technology
January 2, 2008 10:50 AM - Washington University in St. Louis.

The element that lifts things like balloons, spirits and voice ranges is being depleted so rapidly in the world's largest reserve, outside of Amarillo, Texas, that supplies are expected to be depleted there within the next eight years. This deflates more than the Goodyear blimp and party favors. Its larger impact is on science and technology, according to Lee Sobotka, Ph.D., professor of chemistry and physics in Arts & Sciences at Washington University in St. Louis.

LONDON (Reuters) - A married couple who sailed to America from England around 1630 are the reason why thousands of people in the United States are at higher risk of a hereditary form of colon cancer, researchers said on Wednesday. Using a genetic fingerprint, a U.S. team traced back a so-called founder genetic mutation to the couple found among two large families currently living in Utah and New York.

New plant study reveals a 'deeply hidden' layer of the transcriptome
January 1, 2008 09:55 PM - Salk Institute for Biological Studies

La Jolla, CA – Cells keep a close watch over the transcriptome – the totality of all parts of the genome that are expressed in any given cell at any given time. Researchers at the Salk Institute for Biological Studies and the University of Missouri-Kansas City have now teamed up to peel back another layer of transcriptional regulation and gain new insight into how genomes work.

Lack of deep sleep may increase risk of type 2 diabetes

Chicago - Suppression of slow-wave sleep in healthy young adults significantly decreases their ability to regulate blood-sugar levels and increases the risk of type 2 diabetes, report researchers at the University of Chicago Medical Center in the “Early Edition” of the Proceedings of the National Academy of Science.

Beijing introduces cleaner fuel standards
January 1, 2008 08:36 PM - Reuters

BEIJING (Reuters) - China has introduced cleaner fuel standards in its capital Beijing, its latest effort to curb the city's notorious pollution ahead of the Olympic Games in August. Under the new standards, retailers will be required to supply gasoline and diesel equivalent to the Euro IV standard, a move that will cut emissions of acid rain-causing sulphur dioxide by 1,840 tonnes, the China Daily said on Wednesday, citing Beijing's Environmental Protection Bureau.

Politics and graft undermine African health care
January 1, 2008 08:03 PM - Reuters

LIBREVILLE (Reuters) - The crowd of African women are tired and angry after hours waiting in the hot sun, but the officials will not vaccinate their children until the president inaugurates the campaign on state television. When he finally does so, half a day has been lost from the five-day vaccination scheme. It is a small reminder that, for health care in Africa, politics can be as decisive as poverty.
