Shoulder motion after rotator cuff surgery remains significantly different when compared to the patient's opposite shoulder, according to a Henry Ford Hospital study.In a study that updated prior findings, researchers used X-rays providing a 3D view of motion of the arm bone in relation to the shoulder blade, to compared motion in the shoulders of 22 patients who had arthroscopic surgical repair...

In a technique that could eventually shed light on how gene expression influences human disease, scientists have for the first time ever successfully visualized single molecules of naturally occurring messenger RNA transcribed in living mammalian cells.

In a technique that could eventually shed light on how gene expression influences human disease, scientists at Albert Einstein College of Medicine of Yeshiva University have for the first time ever successfully visualized single molecules of naturally occurring messenger RNA transcribed in living mammalian cells. The scientific achievement is detailed in the Jan. 16 online edition of Nature...

Researchers are using inexpensive LCD projectors to control the brain and muscles of tiny organisms, including freely moving worms. This technology advances the field of optogenetics, which has given researchers unparalleled control over brain circuits in laboratory animals.

A small slice of RNA inhibits prostate cancer metastasis by suppressing a surface protein commonly found on prostate cancer stem cells. miR-34a targets a surface protein common to cancer stem cells and associated with tumor development and metastasis. When the micro RNA stifles CD44, it inhibits formation of prostate stem cells. Researchers blocked tumor formation, shrunk tumors and inhibited...

Michigan State University researchers attempting to increase the genetic base of today's most common cultivated strawberry (F. ananassa) and introduce novel genetic diversity into the cultivated gene pool crossed elite clones of two wild strawberry species and hybridized them to produce 26 reconstructed populations. The study found that the reconstruction of F. ananassa by crossing elite genotypes...

Researchers have developed a new technique that allows them to monitor the tiny branches of neurons in a live brain for months at a time. Neuroscientists will now be able to monitor the microscopic changes that occur over the course of progressive brain disease.

Scientists have identified a protein that acts as a "master switch" in certain white blood cells, determining whether they promote or inhibit inflammation. The study, published in the journal Nature Immunology, could help researchers look for new treatments for diseases such as rheumatoid arthritis that involve excessive inflammation.

Shoulder motion after rotator cuff surgery remains significantly different when compared to the patient's opposite shoulder, according to new study. In a study that updated prior findings, researchers used X-rays providing a 3-D view of motion of the arm bone in relation to the shoulder blade, to compared motion in the shoulders of 22 patients who had arthroscopic surgical repair of tendon tears...

In research described as "a stark warning" to those tempted to start smoking, scientists are reporting that cigarette smoke begins to cause genetic damage within minutes -- not years -- after inhalation into the lungs. Their report is the first human study to detail the way certain substances in tobacco cause DNA damage linked to...

Some ideas are ridiculed until shown to be true. Just ask scientists studying continental drift.

The federal government couldn’t pass climate change legislation, but carbon emissions are down anyway.

A West Virginia coal miner’s daughter, she led a fight against mountaintop-removal mining after her grandson scooped up fistfuls of dead fish in 1996.

California faces the risk of a catastrophic storm that could cause four to five times as much economic damage as a large quake, scientists and emergency planners warn.

Warmer temperatures are exposing secrets long held by the world’s glaciers and snow fields.

Tourists, adventurers and history buffs are lining up to visit the South Pole this year and next in honor of the 100th anniversaries of two polar expeditions.

New findings should serve as a "stark warning" to those considering taking up cigarette smoking.
