The performance of microscopic and nano-scale devices could now be better predicted--and improved--thanks to MIT work with a substance familiar to any kid: bubbles.

Ancient reptile is efficient chewer
Researchers have discovered that a small mammal-like reptile that lived 260 million years ago is the first known efficient land vertebrate chewer -- able to use a shearing chewing action to break down tough vegetation.

Study finds nonviral gene therapy for severe hemophilia a is safe with early signs of benefit
A phase I study at Beth Israel Deaconess Medical Center has demonstrated that a factor VIII gene therapy-based treatment for severe hemophilia A is safe and well-tolerated.

At a ceremony today at the Department of Energy facility, researchers noted that the 300,000-watt radiant plasma source is the most powerful lamp in the world.

Magee-Womens Research Institute study finds undiagnosed sexually transmitted disease infection rate nearly 1 in 5 among adolescent females
Researchers at Magee-Womens Research Institute found undiagnosed sexually transmitted diseases in 18 percent of teenage girls who provided vaginal samples they collected themselves during a two-year study.

DNA evidence calls Irish potato famine theory into question
For years, scientists thought they knew which strain of late blight caused the great Irish potato famine of the 1840s, a catastrophic crop failure that changed the course of European and American history.

'Fast track' prostate cancer surgery gets patients home faster but just as satisfied
A new approach to prostate cancer surgery using a combination of existing techniques may help men get home within 24 hours of having their prostates removed - without making them less satisfied with their care or putting them at extra risk of complications.

Astronomers: mysterious brown dwarfs likely 'failed stars'
An international research team led by University of Florida astronomers announced Thursday (6/7) it has found dusty disks surrounding numerous faint objects believed to be

New environmental management and life cycle technologies for the shipbuilding industry
The University of New Orleans recently licensed two technologies developed in the College of Engineering to a Louisiana-based software development firm.

Astronomers discover unique link between stellar death and birth
Astronomers from the University of Colorado at Boulder and the University of California at Berkeley have discovered a key building block for new stars in the rapidly expanding remains of an ancient stellar explosion.

Scientists find that heart muscle cells regenerate after a heart attack
Challenging one of medicine's long-standing beliefs, scientists have found the strongest evidence to date that human heart muscle cells regenerate after a heart attack.

Pioneering hip replacement surgery sends patients home the day after the operation
A new approach to hip replacement surgery done through small portals instead of a large, 12 to 18 inch incision used in traditional hip replacement surgery, dramatically reduces time in the hospital, pain and expenses.

Chemists characterize regulators of zinc intake and export in cells
Zinc is vital to cell function, but the metal can be dangerous in excess.

Earliest chewing herbivore ever found spurred vertebrate life on land, scientists find
The advent of chewing by a group of herbivores 260 million years ago may have signaled one of the first great bursts of vertebrate life on land, say paleontologists from the University of Toronto and Duke University.

New coral record generated by Scripps researchers connects climate change in three oceans
Coral extracted from a remote central Pacific island has helped scientists at Scripps construct a valuable new record of climate conditions during the 20th century.

Catholic University chemist receives award from world's largest scientific society
Dr. Diane M. Bunce of Catholic University in Washington, D.C.

Star factory near galactic center bathed in high-energy X-rays
Astronomers have found a new phenomenon near the crowded core of the Milky Way galaxy: a cauldron of 60-million degree gas enveloping a cluster of young stars.

NASA Marshall scientists capture historic, first focused high-energy X-ray images of astronomical objects

Writing in Nature, scientists identify genes key to differentiating top from bottom in plant leaves
Biologists at the University of Pennsylvania and the University of Wisconsin have identified some of the first genes known to have a hand in differentiating top from bottom in plant leaves, a subtle morphological distinction that has profound implications for development and function across a wide range of plant species.

New software streamlines the search for disease-causing genes
One of the greatest challenges in molecular medicine is identifying the genes that cause specific diseases - often a painstaking process requiring months of laboratory trial and error.
