Global Climate Change Action

New research reveals for the first time how our brains coordinate two different types of attention and why we may be temporarily blinded by surprises.

Researchers are the first to fully characterize a special type of stem cell, endothelial progenitor cells (EPCs) that exist in circulating blood, to see if they can behave as endothelial cells in the body when cultured on a bioengineered surface. The results show promise for a new generation of tissue-engineered vascular grafts which could improve the success rate of surgery for peripheral arterial disease.

Space physicists have identified the impact of the Sun on Mars' atmosphere. The scientists report that Mars is constantly losing part of its atmosphere to space. The new study shows that pressure from solar wind pulses is a significant contributor to Mars's atmospheric escape.

A low-cost water purification technique could help drastically reduce the incidence of waterborne disease in the developing world. The procedure, which uses seeds from the Moringa oleifera tree, can produce a 90.00% to 99.99% bacterial reduction in previously untreated water.

Obese teenage girls with a greater ratio of visceral fat (fat around internal organs) to subcutaneous fat (fat found just beneath the skin) are likely to have lower bone density than peers with a lower ratio of visceral to subcutaneous fat, according to a new study.

Total knee arthroplasty patients may be able to participate in high-impact sports without increasing risk of early implant failure, according to a new study.

Scientists have discovered a previously unknown cellular "switch" that may provide researchers with a new means of triggering programmed cell death, findings with implications for treating cancer.

Scientists have succeeded in growing empty particles derived from a plant virus and have made them carry useful chemicals. The external surface of these nano containers could be decorated with molecules that guide them to where they are needed in the body, before the chemical load is discharged to exert its effect on diseased cells. The containers are particles of the Cowpea mosaic virus, which is ideally suited for designing biomaterial at the nanoscale.

Repair proteins appear to efficiently scan the genome for errors by jumping like fleas between DNA molecules, sliding along the strands, and perhaps pausing at suspicious spots, say researchers who tagged the proteins with quantum dots to watch the action unfold.

Engineers and doctors have designed a new tool for operating on the inner ear with maximum precision, reducing the possibility of damage to the auditory function during the surgery. This is the first micromanipulator specifically for operations involving cochlear and middle ear implants, of which about a hundred are carried out in this hospital annually.

Scientists have discovered a new mechanism that governs this pathway and in the process identified a novel potential therapeutic target for controlling fat metabolism.

African-Americans age 65 and younger are more than twice as likely to have a stroke compared with Caucasians in any region, and people who have a stroke are more likely to die in the South than elsewhere, according to researchers.
