A study by scientists at the University of California, San Diego and UC Irvine has identified an enzyme called a proteasome phosphatase that appears to regulate removal of damaged proteins from a cell. The understanding of how this process works could have important implications for numerous diseases, including cancer and Parkinson's disease.

PHILADELPHIA - Despite what Hollywood would have you believe, not all epidemics involve people suffering from zombie-like symptoms--some can only be uncovered through door-to-door epidemiology and advanced mathematics.
New drug delivery systems, solar cells, industrial catalysts and video displays are among the potential applications of special particles that possess two chemically distinct sides. These particles are named after the two-faced Roman god Janus and their twin chemical faces allow them to form novel structures and new materials.
Reston, VA (Sept. 27, 2011) – According to a recent poll of 1,000 American voters conducted for the American College of Radiology, nearly 9-in-10 women reported that having a regular mammogram gave them a feeling of control over their own health care. Nearly 90 percent of women who had a mammogram considered mammograms important to their health and well-being.
The poll, conducted Aug. 31 – Sept. 6, also showed that 86 percent of women report having a mammogram in last two years.
New research on public perceptions about cancer reveals that 50-year-old ideas still hold sway while many current lifestyle messages are not getting through.
On the positive side, however, the vast majority of people now believe cancer is curable.
Experts at the University of Leicester and Leicester's Hospitals carried out the research to assess patients' beliefs about the causes of cancer, which was funded by the Leicestershire-based charity Hope Against Cancer.
The way in which global warming causes many of the world's organisms to shrink has been revealed by new research from Queen Mary, University of London.
Almost all cold-blooded organisms are affected by a phenomenon known as the 'temperature-size rule', which describes how individuals of the same species reach a smaller adult size when reared at warmer temperatures. But until now, scientists have not fully understood how these size changes take place.
BEER-SHEVA, ISRAEL, September 27, 2011 — Ben-Gurion University of the Negev (BGU) researchers have discovered deep freshwater springs on the Dead Sea floor that feed into this rapidly dwindling body of water.
In the first-ever Dead Sea diving expedition, the researchers also found new types of micro-organisms growing around fissures in the sea floor as part of a collaboration with the Max Planck Institute of Marine Microbiology scientists in Germany.
Amsterdam, The Netherlands: Emissions from livestock farms cause asthma and COPD patients living nearby to experience more exacerbations, according to research presented today at the European Respiratory Society's Annual Congress in Amsterdam.
Also, chances of contracting Q fever from nearby sheep and goat farms increased with the number of animals rather than with the number of farms, the research found, hinting at higher health risks from 'mega farms'.
DURHAM, N.C. – Adding another incentive to exercise, scientists at Duke University Medical Center have found that physical activity improves arthritis symptoms even among obese mice that continue to chow down on a high-fat diet.
The insight suggests that excess weight alone isn't what causes the aches and pains of osteoarthritis, despite the long-held notion that carrying extra pounds strains the joints and leads to the inflammatory condition.
Published Sept. 27 online in the journal Arthritis & Rheumatism, the findings are now being tested in people.
Stockholm, Sweden: Children born after their mothers were treated with chemotherapy during pregnancy appear to be unaffected by the experience in terms of the development of their mental processes and the normal functioning of their hearts, according to new research presented at the 2011 European Multidisciplinary Cancer Congress [1].
A genomic study of chronic blood cancer - a precursor to leukaemia - has discovered gene mutations that could enable diagnosis using only a blood test, avoiding the need for an invasive and painful bone marrow biopsy.
The risk of depression appears to decrease for women with increasing consumption of caffeinated coffee, according to a report in the September 26 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
For decades, laboratory mice have been widely used in research aimed at understanding which genes are involved in various illnesses. But actual variations in past gene sequences of mice were unknown. While researchers were able to determine that a variant affecting disease was in a certain region, they couldn't pinpoint the exact set of variants in that region.
Cold Spring Harbor, NY – Scientists at Cold Spring Harbor Laboratory (CSHL) and the University of Southern California (USC) have uncovered intriguing new evidence helping to explain one of the ways in which a stem cell's fate can be determined.
A shorter course of radiation treatment that delivers higher doses of radiation per day in fewer days (hypofractionation) is as effective in decreasing intermediate to high-risk prostate cancer from returning as conventional radiation therapy at five years after treatment, according to a randomized trial presented at the plenary session, October 3, 2011, at the 53rdAnnual Meeting of the American Society for Radiation Oncology (ASTRO).
