Arthroscopic treatment of common hip problem improves range of motion
Arthroscopic treatment of a common hip problem that leads to arthritis is successful in terms of restoring range of motion, according to results from a recent Hospital for Special Surgery study.

High-resolution imaging technology reveals cellular details of coronary arteries
Researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed a one-micrometer-resolution version of the intravascular imaging technology optical coherence tomography that can reveal cellular and subcellular features of coronary artery disease.

Vitamin D lower in NFL football players who suffered muscled injuries, study reports
Vitamin D deficiency has been known to cause an assortment of health problems, a recent study being presented at the American Orthopaedic Society for Sports Medicine's Annual Meeting in San Diego today, suggests that lack of the vitamin might also increase the chance of muscle injuries in athletes, specifically NFL football players.

Unlocking the genetics and biology of ankylosing spondylitis
A study involving over 5,000 people living with the joint disorder ankylosing spondylitis has identified a series of genetic variants associated with increased susceptibility to the condition as well as providing new clues to how the condition may be treated in the future.

Climate change reducing ocean's carbon dioxide uptake
How deep is the ocean's capacity to buffer against climate change?

New genetic clues for schizophrenia
De novo mutations -- genetic errors that are present in patients but not in their parents -- are more frequent in schizophrenic patients than in normal individuals, according to an international group of scientists led by Dr.

Ant colonies: Behavioral variability wins
Evolutionary biologists at Mainz University found that ant colonies are more productive and raise more offspring when the workers in the colony display considerable variation in their levels of aggression.

Quick test can predict immune responses to flu shots
Researchers at the Emory Vaccine Center have developed a method for predicting whether someone will produce high levels of antibodies against a flu shot a few days after vaccination.

Olympia hypothesis: Tsunamis buried the cult site on the Peloponnese
Olympia, site of the famous Temple of Zeus and original venue of the Olympic Games in ancient Greece, was presumably destroyed by repeated tsunamis that traveled considerable distances inland, and not by earthquake and river floods as has been assumed to date.

Genetic study sheds new light on auto-immune arthritis
Researchers are one step closer to understanding how an individual's genetic make-up predisposes them to Ankylosing Spondylitis (AS), a common auto-immune arthritis which causes pain and stiffness of the spine, and in serious cases, progressive fusion of the vertebrae and other affected joints.

Study identifies patients who should not undergo surgery for a snapping hip tendon
Researchers at Hospital for Special Surgery have identified a group of patients who may have increased difficulty for surgical treatment of a snapping psoas, a condition that usually develops because a teenager or young adult has a pelvis that grows faster than their psoas tendon.

Scientists discover first gonorrhea strain resistant to all available antibiotics
An international research team has discovered a strain of gonorrhea resistant to all currently available antibiotics.

U of T researchers build an antenna for light
University of Toronto researchers have derived inspiration from the photosynthetic apparatus in plants to engineer a new generation of nanomaterials that control and direct the energy absorbed from light.

Light propagation controlled in photonic chips -- major breakthrough in telecommunications field
Columbia Engineering researchers have built optical nanostructures that enable them to slow photons down and fully control light dispersion.

A murder in the magpie's nest
A brutal case of infanticide has been recently reported in the black-billed magpie.

UW-Madison scientists played role in potato genome project
University of Wisconsin-Madison scientists are part of an international consortium that has successfully sequenced and analyzed the potato genome.
