DURHAM, N.C. -- Brain imaging using radioactive dye can detect early evidence of Alzheimer's disease that may predict future cognitive decline among adults with mild or no cognitive impairment, according to a 36-month follow-up study led by Duke Medicine.

The national, multicenter study confirms earlier findings suggesting that identifying silent beta-amyloid plaque build-up in the brain could help guide care and treatment decisions for patients at risk for Alzheimer's. The findings appeared online March 11, 2014, in Molecular Psychiatry, a Nature Publishing Group journal.

Ulnar collateral ligament (UCLR) reconstruction, a common injury for pitchers in Major League Baseball, is often called "Tommy John Surgery" after the New York Yankees pitcher who made it famous, In 1974, Dr. Frank Jobe made medical history when he replaced the pitcher's torn medial collateral ligament with a tendon from John's forearm and he went on to pitch for 14 more years and added 164 more victories - after an injury that had been career-ending in the past.

Results out today show that pitchers win more games following Tommy John Surgery but another paper disagrees. The scholars at Henry Ford Hospital say the performance decline is notabled and that they the largest cohort of professional pitchers to date to examine the issue.

Ulnar collateral ligament (UCLR) reconstruction, commonly called "Tommy John Surgery" after the New York Yankees pitcher who made it famous, is a procedure performed on Major League Baseball pitchers after they get a damaged or torn ulnar collateral ligament, a common elbow injury.  In 1974, Dr. Frank Jobe made medical history when he replaced the pitcher's torn medial collateral ligament with a tendon from John's forearm.

John then pitched for 14 more years and added 164 more victories - after an injury that had been career-ending in the past.

What do people living in Boston, Pittsburgh and Los Angeles have in common? From coast to coast, prairie to desert, people love their lawns.  

If only there was a study that dug deeper, like examining differences in fertilization and irrigation practices.  

Don't scoff, the authors of a paper in the Proceedings of the National Academy of Sciences assure us that with 80 percent of Americans living in urban or suburban neighborhoods, understanding urban lawn care is vital to sustainability planning.

An international team of researchers has found evidence that the steam and heat from volcanoes and heated rocks allowed many species of plants and animals to survive past ice ages, helping scientists understand how species respond to climate change.

The research could solve a long-running mystery about how some species survived and continued to evolve through past ice ages in parts of the planet covered by glaciers.

The team, led by Dr Ceridwen Fraser from the Australian National University and Dr Aleks Terauds from the Australian Antarctic Division, studied tens of thousands of records of Antarctic species, collected over decades by hundreds of researchers, and found there are more species close to volcanoes, and fewer further away.

In end-stage lung disease, transplantation is sometimes the only viable therapeutic option, but organ availability is limited and rejection presents an additional challenge. Innovative research efforts in the field of tissue regeneration, including pioneering discoveries by University of Vermont (UVM) Professor of Medicine Daniel Weiss, M.D., Ph.D., and colleagues, holds promise for this population, which includes an estimated 12.7 million people with chronic obstructive pulmonary disorder (COPD), the third leading cause of death in the U.S.
