Scientists measure communication between stem cell-derived motor neurons and muscle cells Posted: 04 May 2012 02:20 PM PDT Researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish.

Students more likely to be fit when physical education is mandatory Posted: 04 May 2012 02:20 PM PDT Fifth graders in California public school districts that comply with the state's mandatory physical education requirement are more likely to have better fitness levels than students in districts that don't comply, according to a new study.

Parents important in steering kids away from sedentary activities Posted: 04 May 2012 02:19 PM PDT Parents can have a significant impact in steering young children away from too much time spent in sedentary pursuits.

New technique could identify drugs that help fight broad range of viruses Posted: 04 May 2012 02:19 PM PDT Results of a new study demonstrate the feasibility of a novel strategy in drug discovery: screening large numbers of existing drugs — often already approved for other uses — to see which ones activate genes that boost natural immunity.

Expensive hospital readmissions linked to health-care-associated infections Posted: 04 May 2012 10:59 AM PDT New research finds a strong link between healthcare-associated infections and patient readmission after an initial hospital stay. The findings suggest that reducing such infections could help reduce readmissions, considered to be a major driver of unnecessary healthcare spending and increased patient morbidity and mortality.

Scientists identify prostate cancer stem cells among low-PSA cells Posted: 04 May 2012 10:59 AM PDT Prostate cancer cells that defy treatment and display heightened tumor-generating capacity can be identified by levels of prostate specific antigen (PSA) expressed in the tumor cells, scientists have found.

Scientists aim to kill lung tumors Posted: 04 May 2012 10:58 AM PDT Enzyme regulates the division of tumor cells and blood vessel growth in the cancer tissue.

New muscular dystrophy treatment approach developed using human stem cells Posted: 04 May 2012 08:05 AM PDT Researchers have effectively treated muscular dystrophy in mice using human stem cells derived from a new process that -- for the first time -- makes the production of human muscle cells from stem cells efficient and effective.

Beehive extract shows potential as prostate cancer treatment Posted: 04 May 2012 08:04 AM PDT An over-the-counter natural remedy derived from honeybee hives arrests the growth of prostate cancer cells and tumors in mice, according to a new article. Researchers combined traditional cancer research methods with cutting-edge proteomics to find that CAPE arrests early-stage prostate cancer by shutting down the tumor cells' system for detecting sources of nutrition.

Sifting through 'junk' to find colorectal cancer clues Posted: 03 May 2012 01:20 PM PDT Analysis of non-coding "junk" DNA has identified switches capable of turning on or off genes associated with the very common cancer.

Key contribution to Melanesian blonde hair color discovered Posted: 03 May 2012 11:25 AM PDT Researchers studying pigmentation in the South Pacific have uncovered a key genetic contribution to hair color. The findings reveal a functional genetic variant which has led the islanders to have simultaneously the darkest skin pigmentation outside of Africa and the highest prevalence of blonde hair outside of Europe.

Anthropologists discover new research use for dental plaque: Examining diets of ancient peoples Posted: 02 May 2012 03:48 PM PDT While we may brush and floss tirelessly and our dentists may scrape and pick at our teeth to minimize the formation of plaque known as tartar or dental calculus, anthropologists may be rejoicing at the fact that past civilizations were not so careful with dental hygiene. Researchers have discovered that particles of plaque removed from teeth of ancient populations may provide clues about their diets.
