Lack of oversight by CMS to ensure private Medicare drug plans have anti-fraud programs in place 'risks significant use of funds,' according to GAO

CMS has not conducted audits to ensure that Medicare prescription drug plans have implemented programs to prevent fraud as required by law, a lack of oversight that "risks significant misuse of funds in this $39 billion program," according to a Government Accountability Office report scheduled for release on Monday, the AP/Orlando Sentinel reports. For the report, GAO examined five unnamed plans to determine whether they met requirements to participate in the Medicare prescription benefit.

Brown fat points to new ways to fight obesity

A surprise discovery -- that calorie-burning brown fat can be produced experimentally from muscle precursor cells in mice -- raises the prospect of new ways to fight obesity and overweight, say scientists from Dana-Farber Cancer Institute.

Lycopene molecules in tomatoes could help fight cancer

Turning up the heat on the red tomato during processing has the potential to give the popular garden staple added disease-fighting power, Ohio State University research suggests.

79 million adults with medical bill problems or medical debt in U.S.

The proportion of working-age Americans who have medical bill problems or who are paying off medical debt climbed from 34 percent to 41 percent between 2005 and 2007, bringing the total to 72 million, according to recent survey findings from The Commonwealth Fund. In addition, 7 million adults age 65 and over also had problems paying medical bills, for a total of 79 million adults with medical bill problems or medical debt.

Mosquitoes smell DEET and stay away

Spray yourself with a DEET-based insect repellent and the mosquitoes will leave you alone. But why? They flee because of their intense dislike for the smell of the chemical repellent and not because DEET jams their sense of smell, report researchers at the University of California, Davis.

New understanding on how Chilli peppers increase metabolism and body temperature

Chilli peppers can do more than just make you feel hot, reports a study in the August 1 Journal of Biological Chemistry; the active chemical in peppers can directly induce thermogenesis, the process by which cells convert energy into heat.

Researchers discover novel kind of learning gene

Scientists at the Freie Universität Berlin have come one step closer to unraveling the molecular basis of learning. A team led by neurobiologist Bjorn Brembs has discovered the first gene for operant conditioning in the fruit fly Drosophila.

Suprising finding on aging

Age may not be rust after all. Specific genetic instructions drive aging in worms, report researchers at the Stanford University School of Medicine. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage akin to rust, and implies science might eventually halt or even reverse the ravages of age.

House hearing to consider more federal funds for state Medicaid programs as part of second economic stimulus package

The House Energy and Commerce Health Subcommittee on Tuesday plans to hold a hearing that "might turn up the heat on congressional leaders to include Medicaid relief for states in a second economic stimulus package," CongressDaily reports.

Heat waves when in hospital

Deaths due to high temperatures occur so quickly that patients do not have time to be admitted to hospital. This is why prevention campaigns are necessary to try and reduce the negative effects of the heat on health. This is pointed out in new research undertaken at the Hospital Universitario Gregorio Maranon, Madrid.

Nanotechnology, biomolecules, and light unite to "cook" cancer cells

Using carbon nanotubes linked to tumor-homing antibodies, a research team headed by Ellen Vitetta, Ph.D., M.D., of the University of Texas Southwestern Medical Center has shown that they can specifically kill the targeted tumor cells using near-infrared light. This work appears in the Proceedings of the National Academy of Sciences.

Male cyclists risk sexual problems if they don't choose the right bike

Men who take up cycling in an effort to stay fit, do their bit for the environment or avoid spiralling motoring costs, could be harming their health if they don't choose the right bicycle.

Research sheds light on the molecular basis of SIDS

Sudden Infant Death Syndrome (SIDS) is a condition that unexpectedly and unexplainably takes the lives of seemingly healthy babies aged between a month and a year.

ETH Zurich and IBM improve diagnosis of osteoporosis

With the goal of developing an accurate, powerful and fast method to automate the ana-lysis of bone strength, scientists of the ETH Zurich Departments of Mechanical and Pro-cess Engineering and Computer Science teamed up with supercomputing experts at IBM's Zurich Research Laboratory. The breakthrough method developed by the team combines density measurements with a large-scale mechanical analysis of the inner-bone microstructure.

Yeast-based vaccine induces immune responses and reduces tumor size in mice

Scientists have found that vaccination with a heat-killed, non-toxic yeast that is genetically engineered to manufacture a common tumor protein can induce specific and repeated anti-tumor immune responses in mice.

Wound-cleaning laser kills harmful bacteria

A laser-activated antimicrobial offers hope for new treatments of bacterial infections, even those that are resistant to current drugs. Research published today in the open access journal BMC Microbiology describes the use of a dye, indocyanine green, which produces bacteria-killing chemicals when lit by a specific kind of laser light.

Laser "microscalpel" to target individual cancer cells

Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases.

Oral cannabis ineffective in treating acute pain

A study published in the July issue of the Journal Anesthesiology discovered that oral cannabis (a form of medical marijuana) not only failed to alleviate certain types of pain in human volunteers but, surprisingly, it instead caused increased sensitivity to some forms of pain.
