Dr. Anthony Fauci reflects on 25 years of HIV

Dr. Anthony Fauci reflects on 25 years of HIV
On the 25th anniversary of the first scientific article linking a retrovirus to AIDS, Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, reflects in an essay in Nature on his experience treating and studying HIV/AIDS for the past quarter century. Outlining the peaks and valleys of the scientific communitys journey so far, Dr. Fauci writes, we must learn from........Go to the Infectious disease blog (Added on 5/15/2008 8:25:56 PM)

Doubt on Risk of Death from Higher Salt Intake

Doubt on Risk of Death from Higher Salt Intake
Contrary to long-held assumptions, high-salt diets may not increase the risk of death, as per researchers from the Albert Einstein College of Medicine of Yeshiva University. They reached their conclusion after examining dietary intake among a nationally representative sample of adults in the U.S. The Einstein scientists actually observed a significantly increased risk of death from cardiovascular disease (CVD) linked to lower sodium diets.

Risk For Developing Breast Cancer

Risk For Developing Breast Cancer
A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help scientists more accurately determine a woman's risk for developing breast cancer and provide a new approach for therapy, UT Southwestern Medical Center scientists have found.

Teens reach linguistic peak in online chat

Teens reach linguistic peak in online chat
Parents and teachers worry that teenagers use of these and other forms of online shorthand is harming their language skills. Perhaps they will take comfort from a study suggesting that instant messaging (IM) actually represents an expansive new linguistic renaissance. Sali Tagliamonte and Derek Denis at the University of Toronto, Canada, say teenagers risk the disapproval of their elders if they use slang, and the scorn of their friends if........Go to the Society medical news blog (Added on 5/14/2008 8:51:05 PM)

Attitudes to stem cell research

Attitudes to stem cell research
Unlike most scientific and technological advances, which tend to take their place silently in society, biotechnology often finds itself the center of public debate and regulatory attention, due partly to the moral issues posed by a number of of its applications.

Adding ultrasound screening to mammography

Adding ultrasound screening to mammography
Adding a screening ultrasound examination to routine mammography reveals more breast cancers than mammography alone, as per results of a major new clinical trial. The trial, however, also observed that adding an ultrasound exam also increases the rate of false positive findings and unnecessary biopsies.

What's the difference between a human and a fruit fly?
Fruit flies are dramatically different from humans not in their number of genes, but in the number of protein interactions in their bodies, as per researchers who have developed a new way of estimating the total number of interactions between proteins in any organism.

Number Of Fat Cells Remains Constant In All Body Types

Number Of Fat Cells Remains Constant In All Body Types
The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped scientists determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the actual number of fat cells. These results could help scientists develop new pharmaceuticals to........Go to the Weight watcher's blog (Added on 5/11/2008 10:13:41 AM)

Researchers are beginning to unravel the question why people distinctly vary in size. In cooperation with researchers of the HelmholtzZentrum M√ľnchen, an international genome-wide study has discovered ten new genes that influence body height and thus provides new insights into biological pathways that are important for human growth.

Is divorce bad for the parents?
The elderly are cared for by their adult children regardless of their marital status. In a unique study funded by the Economic and Social Research Council, scientists found British adult children help their elderly parents as per current need (i.e. health) rather than past behaviour. This contrasts with other countries such as the US, where parents with a history of divorce see less of their children and receive less help from them.

How slow growth as a fetus can cause diabetes as an adult

How slow growth as a fetus can cause diabetes as an adult
Intrauterine growth retardation (IUGR), which results in a baby having a low weight at birth, has been associated with the development of type 2 diabetes in adulthood. It has been suggested that this is because the expression of key genes is altered during fetal development and that this affects disease susceptibility during the later part of life. Evidence to support this hypothesis and indicating that the changes in gene expression might be........Go to the OBGYN news blog (Added on 5/8/2008 9:13:51 PM)

Teenagers and young adults across Europe drink and take drugs as part of deliberate sexual strategies. Findings published recently in BioMed Centrals open access journal, BMC Public Health, reveal that a third of 16-35 year old males and a quarter of females surveyed are drinking alcohol to increase their chances of sex, while cocaine, ecstasy and cannabis are intentionally used to enhance sexual arousal or prolong sex.

New Cancer Gene Discovered

New Cancer Gene Discovered
Scientists at the OU Cancer Institute have identified a new gene that causes cancer. The ground-breaking research appears Monday in Nature's cancer journal Oncogene. The gene and its protein, both called RBM3, are vital for cell division in normal cells. In cancers, low oxygen levels in the tumors cause the amount of this protein to go up dramatically. This causes cancer cells to divide uncontrollably, leading to increased tumor formation. ........Go to the Cancer-blog (Added on 5/8/2008 8:47:45 PM)

The developing nervous system makes far more nerve cells than are needed to ensure target organs and tissues are properly connected to the nervous system.
