Approximately 21 million visits were made to physicians' offices due to back problems in 2006. While countless adults experience back pain and stiffness, many suffer from serious spine and back conditions –including injury, herniated discs and the deterioration of the vertebrae. Three new studies presented at the 2010 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) detail advances in back care and treatment options for specific back and spine conditions. Each of the following three studies consider and report on the patients' best outcomes and options:

At age 55, men can expect another 15 years of sexual activity, but women that age should expect less than 11 years, according to a study by University of Chicago researchers published early online March 10 by the British Medical Journal. Men in good or excellent health at 55 can add 5 to 7 years to that number. Equally healthy women gain slightly less, 3 to 6 years.

ITHACA, N.Y. — Consider this T-shirt: It can monitor your heart rate and breathing, analyze your sweat and even cool you off on a hot summer's day. What about a pillow that monitors your brain waves, or a solar-powered dress that can charge your ipod or MP4 player? This is not science fiction – this is cotton in 2010.

WASHINGTON, March 10—In the future, getting a broadband connection might be as simple as flipping on a light switch. In fact, according to a group of researchers from Germany, the light coming from the lamps in your home could one day encode a wireless broadband signal.

MADISON, WI, MARCH 8, 2010--Polycyclic aromatic hydrocarbons (PAHs) are components of petroleum products such as gasoline, coal, and oil. They are also produced as by-products of the combustion of fuels including petroleum and fire wood. PAHs can cause cancer and other health effects. Because they are produced during combustion, they are ubiquitous, and their levels are high enough to be a concern in all urban waterways.

Pioneering French physicists Marie and Pierre Curie have the curie, a unit of radioactivity, named after them. Renowned inventor Nikola Tesla is honored with the tesla, which measures a magnetic field. And now, the Rosenfeld, proposed as a unit for electricity savings, will be named after the man seen by many people as the godfather of energy efficiency, Arthur Rosenfeld.

A husband and wife research team has found a way to use the sleeve-like cover on bone to heal serious bone injuries faster and more simply than current methods. And they've developed an artificial sleeve that spurs fast healing when a car wreck, bomb blast or disease leaves too little cover.

ANN ARBOR, Mich. – Admission to a hospital when most of the beds are already full can be deadly for patients, according to a new University of Michigan Health System study showing high occupancy increases the risk of dying in the hospital by 5.6 percent.

For the study, published in the March issue of Medical Care, researchers evaluated a set of critical factors that can affect hospital deaths: hospital occupancy, nurse staffing levels, weekend admission and seasonal influenza.

The project, directed by CSIC researcher Cristina Sánchez Carretero was completed through close collaboration with associations for victims and those affected.

On Thursday March 11, the project will end with its transfer to the Spanish Railway Foundation and the digitized catalog will be available for study with prior approval.

Two papers published this week in PLoS Medicine by Margaret Kruk and colleagues investigate surgical provision in eight district hospitals in three sub-Saharan African countries. The authors, from the USA and Africa, show low levels of surgical care provision, a lack of specialist surgeons and anaesthetists, and low expenditure on surgical provision.

CHAPEL HILL – A one-page, 27-item questionnaire that is available free online is a valid and effective tool to help primary care doctors screen patients for four common psychiatric illnesses, a study led by University of North Carolina at Chapel Hill researchers concludes.

Results of the My Mood Monitor (M-3) checklist study are published in the March/April 2010 issue of Annals of Family Medicine. The checklist was developed by M-3 Information of Bethesda, Md., and is available at www.mymoodmonitor.com.

ITHACA, N.Y. - Another weapon in the arsenal against cancer: Nanoparticles that identify, target and kill specific cancer cells while leaving healthy cells alone.

Led by Carl Batt, the Liberty Hyde Bailey Professor of Food Science, the researchers synthesized nanoparticles – shaped something like a dumbbell – made of gold sandwiched between two pieces of iron oxide. They then attached antibodies, which target a molecule found only in colorectal cancer cells, to the particles. Once bound, the nanoparticles are engulfed by the cancer cells.

Materials such as paper, paint, and biological tissue are opaque because the light that passes through them is scattered in complicated and seemingly random ways. A new experiment conducted by researchers at the City of Paris Industrial Physics and Chemistry Higher Educational Institution (ESPCI) has shown that it's possible to focus light through opaque materials and detect objects hidden behind them, provided you know enough about the material.

The more heterogeneous the community of an online chat channel, the more chances the channel has to survive over time. This has been concluded in a new joint study carried out by researchers of the University of Haifa and the New Jersey Institute of Technology. "This study has shown that an essentially social characteristic significantly influences the survival chances of an online community," says Dr. Daphne Raban of the University of Haifa who took part in the study.

Farmers throughout the world spend an estimated $36 billion a year to buy seeds for crops, especially those with sought after traits such as hardiness and pest-resistance. They can't grow these seeds themselves because the very act of sexual reproduction erases many of those carefully selected traits. So year after year, farmers must purchase new supplies of specially-produced seeds.
