Early Stage Breast-cancer Rates Are Rising As Incidence Of Invasive Ca
Since 1980, the incidence of ductal carcinoma in situ has increased more than sevenfold while the incidence of invasive breast cancer has leveled off. Both trends suggest that widespread mammography screening, among other factors, are catching breast cancer earlier. Novel Hydrogels Invented For Repairing, Regenerating Human Tissue
Scientists have invented a novel biomaterial with surprising antibacterial properties, that can be injected as a low-viscosity gel into a wound where it rigidifies nearly on contact--opening the door to the possibility of delivering a targeted payload of cells and antibiotics to repair the damaged tissue. Pinpointing The Cause Of A Neurodegenerative Disorder
Howard Hughes Medical Institute researchers have discovered how the abnormal repetition of a genetic sequence can have disastrous consequences that lead to the death of neurons that govern balance and motor coordination. The studies bolster the emerging theory that neurodegenerative disorders can be caused by having extra copies of a normal protein, not just a mutated one. Dust-enshrouded Star Looks Similar To Our Sun
Astronomers report evidence of cosmic collisions surrounding a star similar to the sun, approximately 300 light years from Earth. The colliding objects could range in size from the largest asteroids to planets the size of Earth and Mars; the latter type of collision early in the history of our solar system may have produced the Earth's moon, along with huge amounts of interplanetary dusty debris. The discovery is published July 21 in Nature. Scientists Find New Causes For Neurodegeneration
Diseases that cause neurons to break down, such as Alzheimer's, continue to be elusive to scientists and resistant to treatments. A new finding demonstrates an unpredicted link between a virtually unknown signaling molecule and neuron health. Scientists connect the loss of this molecule to massive neurodegeneration in the brain, which plays a key role in the survival of nervous system cells. Natural Compounds Block Autoimmune Response In Diabetes, Arthritis
Natural compounds derived from a sea anemone extract and a shrub plant have been found to block the autoimmune disease response in type 1 diabetes and rheumatoid arthritis, according to University of California, Irvine researchers. Deep Inside Planet Earth, Interplay Of Temperature, Pressure, Chemistr
Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and chemically diverse. This new view of Earth's inner workings depicts the planet as a living organism where events that happen deep inside can affect what happens at its surface, like the rub and slip of tectonic plates and the rumble of the occasional volcano. No Blind Mice, Thanks To University Of Florida Scientists
University of Florida stem cell scientists reported today (Jan. 3) that they have prevented blindness in mice afflicted with a condition similar to one that robs thousands of diabetic Americans of their eyesight each year. JumpTV

Tiny Dust Particles From Asian Deserts Common Over Western United Stat
Dust from the Gobi and Taklimakan deserts in China and Mongolia is routinely present in the air over the western United States during spring months, a researcher has found. He found that in years with large Asian dust storms there was an increase in particles of 2.5 microns or less in the air over the western United States. Particles that small can be inhaled more deeply into the lungs and are a health concern.
