In handling fraudulent stem-cell research articles, journal editors went above and beyond existing procedures to try and verify the findings, but in today’s competitive publishing environment, more stringent, less trusting safeguards are now essential, an independent committee has concluded.
A new type of stethoscope enables doctors to hear the sounds of the body in extremely loud situations, such as during the transportation of wounded soldiers in Blackhawk helicopters.
Researchers investigate the evolution of the bacterium Salmonella typhi and warn of an increased spread of resistant strains.
Roche Holding AG (ROG.VX: Quote, Profile, Research) on Tuesday said there had been no new evidence that resistance to its drug Tamiflu was on the rise, as governments move to deploy the treatment against avian influenza in humans.
An implantable pump can help heart-failure patients live and recover strength while they wait for a transplant. But an evaluation concludes that the UK’s National Health Service should continue to restrict the technology’s use — at least for now.
Wavy leaf thistle was difficult to find along Panhandle highways five years ago. But now the noxious weed can be found moving into pastures, said a Texas Agricultural Experiment Station researcher. Dr. Jerry Michels, Experiment Station entomologist at Bushland, along with Nagendra Earle, a West Texas A&M University graduate student, began looking at controlling the intruding noxious weed with natural controls about two years ago.
Certain women may miss out on routine tests that screen for early signs of breast cancer. Elderly women, women with publicly funded health insurance and women who don’t go to an obstetrician and gynecologist for routine exams are all less likely than others to get a clinical breast exam and a recommendation for a mammogram.
Cancer researchers have found that a gene that is involved in regulating aging also blocks prostate cancer cell growth. They have shown that the enzyme SIRT1 can block the growth of treatment-resistant prostate cancer cells that overexpress a mutation for the androgen receptor. The scientists hope the newly found connection will aid in better understanding the development of prostate cancer and lead to new drugs against the disease.
People who experience their first-ever bout of depression after having a heart attack are at greater risk for future heart problems than are patients who either don?t become clinically depressed after the medical emergency or who were depressed even before the incident, new research shows.
Researchers at New York University and the Scripps Research Institute have discovered a new enzyme, GAPDH, which regulates insulin pathways — a finding that offers a new direction for the treatment of diabetes. The research is reported in the most recent issue of the journal Nature Chemical Biology.
