Shoulder pain...me? how bout you?

Wake up to find your shoulder killing you but don't recall an injury? It could be the start of frozen shoulder, a curse of middle-aged women and one of the most puzzling joint conditions. The shoulder's normally smooth lining becomes so inflamed it resembles cherry Jell-O. That leads to scar tissue, making the shoulder too stiff to move.In fact, doctors can easily confuse early symptoms with a rotator cuff injury — and the wrong physical therapy can worsen a frozen shoulder-in-progress by further irritating it.

Why the mystery? Nobody knows just what triggers frozen shoulder. It seems to strike out of the blue.Diabetics are at higher risk; up to 20 percent get it. Having an underactive thyroid also is a risk factor. Trauma sometimes precedes a frozen shoulder.Add the fact that 70 percent of patients are middle-aged women, and specialists say hormones clearly play some role but they don't know what.Beyond that, it's hard to predict who will get adhesive capsulitis, or how severe a case. It doesn't strike the same shoulder twice, but at least 15 percent of patients eventually suffer a bout in the opposite shoulder.Surrounding the ball of the shoulder is a thin stretchy sac, or capsule. Inflammation in that lining is the start of frozen shoulder, and it causes immense pain.

When the pain starts to wane, that's bad news. It means the capsule is thickening with excess collagen, a sort of scar tissue, that further stiffens the shoulder. Eventually, the body can mostly recover on its own. But it takes so long that most late-stage patients find themselves undergoing painful physical therapy or even surgery to break apart the collagen and spur thawing.


Voyager 2 Detects Odd Shape of Solar System's Edge

SAN FRANCISCO -

At a media teleconference today, NASA scientists announced the Voyager 2 could pass beyond the outermost layer of our solar system, called the "termination shock" sometime within the next year. Sister to a spacecraft Voyager 1, launched in 1977 on a mission to the outer planets .The Voyager 2 crossed the shock boundary Aug. 30 this year, about 10 billion miles away from where its twin crossed. As before, the Voyager 1 spacecraft crossed this boundary between the heliosphere and interstellar space that is called the solar wind termination shock .While Voyager 1 only crossed the shock wave once, Voyager 2 had multiple crossings, because the shock wave sloshes back and forth like surf in a beach . The sloshes allowed many measurements of the velocity, density and temperature of the solar wind. This ''solar wind" , is actually a thin gas of electrically charged particles , blows outward in all directions from the sun, at between 1 million and 2 million mph, forming a bubble called the heliosphere with boundaries far beyond the orbit of Pluto .


Researchers find new deep water coral

A new deep water coral and sponge beds found several thousands of feet below the ocean surface.The a lemon-yellow bamboo coral tree and a giant sponge were discovered last month in the Papahanaumokuakea Marine National Monument by the Pisces V submersible operated by the Hawaii Undersea Research Laboratory (HURL).They were found in depth from 3,000 to 6,000 feet.Randy Kosaki, the National Oceanic and Atmospheric Administration research coordinator said most of the monument is below scuba diving depths .The new found water coral , is potentially protecting so many new species and new records of species that many will not be revealed for decades to come.
