Engineers place tiny synthetic motors inside live human cells

For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. It's not exactly "Fantastic Voyage," but it's close. The nanomotors, which are rocket-shaped metal particles, move around inside the cells, spinning and battering against the cell membrane.

Exposure to Manga comics promotes fruit intake and healthy snack selection

A recent pilot study in Brooklyn, New York, with minority students found that exposure to Manga comics (Japanese comic art) promoting fruit intake significantly improved healthy snack selection. As snacking accounts for up to 27% of children's daily caloric intake, and childhood obesity has been linked to inadequate intake of fruits and vegetables, the results of this study could have wide-reaching implications.

Long-distance signaling molecules tell brain to produce anti-viral interferon

The brain contains a defense system that prevents at least two unrelated viruses-and possibly many more-from invading the brain at large. The research is published online ahead of print in the Journal of Virology.

Mayo Clinic researchers shed light on new mechanism by which prostate cancer develops in men

Mayo Clinic researchers have shed light on a new mechanism by which prostate cancer develops in men. Central to development of nearly all prostate cancer cases are malfunctions in the androgen receptor - the cellular component that binds to male hormones.

People who do shiftwork are more likely to have diet that promotes chronic inflammation

People who do shiftwork are more likely to have a diet that promotes chronic inflammation—which may partly explain the health risks associated with shiftwork, reports a study in the February Journal of Occupational and Environmental Medicine, official publication of the American College of Occupational and Environmental Medicine (ACOEM).

New online resource centre helps to create better strategies for food risks and benefits

Food scare make authorities uneasy. In previous cases, national food safety agencies have not always known how to react, making the public wary. For example, in 2011, the German health authorities incorrectly linked the deadly E. coli outbreak to cucumbers from Spanish greenhouses.

Researchers develop low-power wireless microsystem for hearing aids and implants

Microsystems are at the heart of portable hearing aids and implants. Now researchers are developing a miniature, low-power wireless microsystem to make these medical aids smaller, more comfortable and more efficient.

Researchers shed new light on pain associated with bacterial infections

Components in the outer wall of bacteria directly activate pain sensors, triggering immediate pain and inflammatory responses. This finding by a multinational team of researchers led by Professor Karel Talavera (KU Leuven, Belgium) and Professor Félix Viana (Institute of Neuroscience, Spain) sheds new light on pain associated with bacterial infections and reveals a new target for drugs designed to treat them.

Short-Form OAB questionnaire validated

Researchers from the USA have developed a short form version of the overactive bladder questionnaire, which they say can capture the full spectrum of symptom bother and quality of life impact, while being more convenient than the full version of the test.

Caution against over-intensive BP control in diabetes patients

Very intensive control of blood pressure in patients with Type 2 diabetes does not prevent cognitive decline and may even be counterproductive, suggest findings from the ACCORD MIND substudy.

Low-income countries more prone to obesity, diabetes as TV, computer and car ownership rises

The spread of obesity and type-2 diabetes could become epidemic in low-income countries, as more individuals are able to own higher priced items such as TVs, computers and cars. The findings of an international study, led by Simon Fraser University health sciences professor Scott Lear, are published today in the Canadian Medical Association Journal.

New AAA screening program reduces number of undiagnosed at-risk men by more than 50%

A screening program for abdominal aortic aneurysms, integrated into an electronic health record, dramatically reduced the number of unscreened at-risk men by more than 50 percent within 15 months, according to a Kaiser Permanente study published today in the Journal of Vascular Surgery. An abdominal aortic aneurysm is a balloon-like bulge in the aorta, which - if ruptured - can result in death.

UCLA researchers awarded $6M grant to explore new therapies for spinal-cord injuries

The National Institute of Biomedical Imaging and Bioengineering has awarded UCLA researchers Dr. Daniel Lu (Brentwood) and Dr. Reggie Edgerton (Bel Air) a $6 million, five-year grant to explore new therapies for the approximately 273,000 Americans living with spinal-cord injuries. Some 12,000 Americans suffer such injuries each year.
