An ancient bathtub ring of mammoth fossils

...cient Lake Lewis. PNNL geologists are plotting the deposits to reconstruct the high-water marks of many of the floods, the last of which occurred as recently as 12,000 to 15,000 years ago. "Now is the perfect time to collect geologic and paleontologic data," said George Last, a senior research scientist at...

UW launches study testing adult stem cells for heart damage repair

... heart muscle become narrowed or blocked by plaque deposits and blood clots. Poor blood flow and blood clots "starve" and injure the heart muscle. The American Heart Association estimates that every year, between 125,000 and 250,000 individuals with coronary artery disease develop chronic myocardial ischem...

New biofuels process promises to meet all US transportation needs

...ion's transportation sector could deplete all coal deposits in the United States in about 90 years, whereas H2CAR would enable the known coal reserves to last 140 years. The researchers suggest in the paper the chemical processing steps needed to make the new approach practical. But making the concept econ...

Inhibiting blood to save the brain

... is associated with the accumulation of fibrinogen deposits in the brain of human MS patients. In this study, Akassoglou and colleagues showed that fibrinogen is not merely associated with the damage in MS, but an active participant. Fibrinogen activates macrophage cells in the brain called microglia, causin...

Blocking immune cell action increases Alzheimer's-associated protein deposits

Pharmaceutical compounds found in nation's fresh water

...water from septic tanks located in sand and gravel deposits in Missoula, Montana. Many pharmaceutical and pharmaceutically-active compounds (e.g. caffeine) persist through the human body and are resistant to conventional waste water treatment practices. They are often detected in aquatic environments such ...

Monitoring poisons in the environment -- a woolly matter

...ol was then washed to ensure that only metabolised deposits of heavy metals were detected, rather than anything that had stuck to the outside of the wool. Copper and lead concentrations were then determined using highly sensitive equipment which can accurately detect very small quantities of heavy metals. Thi...

Scientists crack rhino horn riddle

Enzyme shreds Alzheimer's protein

... aging mice with human APP markedly reduced plaque deposits in the animals' brains. Gan and colleagues concluded that "our findings suggest that inhibition or loss of CatB function could interfere with its protective function and promote the development of AD, whereas overexpression of CatB could counteract...

Oldest animal fossils may have been bacteria

...that these bacteria were causing these phosphorite deposits to form," Bailey said. Also in 2005, University of Georgia marine biologists Samantha Joye and Karen Kalanetra, who are co-authors on Bailey's study, found that Thiomargarita can multiply by reductive cell division, a process rare among bacteria bu...

Scientists work to identify genes that contribute to early heart attack risk

...ses. Atherosclerosis is the development of fatty deposits in arteries that leads to blood clot formation, angina, heart attack and stroke. This process can begin in childhood and early adult life. Doctors have known that genetic factors contribute to risk for early atherosclerosis but the exact genes involv...

The Midas Bug -- the bacterial alchemy of gold

...ich may be responsible for one of the largest gold deposits in the world, the Witwatersrand deposit in South Africa." Applying molecular biology techniques, Dr Reith discovered a living biofilm on the surface of gold grains collected. DNA profiling of this biofilm identified 30 bacterial species with popula...

Arctic expedition will investigate alien-like glacier

...001 and collected samples of the water and mineral deposits from the spring, which contained new forms of bacteria and an extremely rare mineral known as vaterite. Sulfur-loving organisms have been found living in extremely hot water around geothermal vents deep in the ocean floor but are seldom observed liv...

U of M study examines kidney stone prevention in astronauts

One of the most common types of kidney stones is caused by the buildup of calcium oxalate. Researchers studied the effects of exercise in pairs of identical twins, sinc...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

One of the puzzles von Andrian has been working on, is how foreign invaders manage to proliferate in the very area, the lymph node, where the imm...

But a new study, published online on April 10 in The Journal of Experimental Medicine, suggests that the heart-healthy effect of one antioxidant has little to do with cholesterol oxidation.
