Three teenage athletes from the Ebola-affected region of Africa will not be allowed to compete at the Youth Olympics in China because of the risk of possible infection, the IOC and local organizers said today.
It's an eye-catching angle in the story of an experimental treatment for Ebola: the drug comes from tobacco plants that were turned into living pharmaceutical factories. Using plants this way can produce complex and valuable proteins for medicines. That approach, studied for about 20 years, hasn't caught on widely in the pharmaceutical industry.
“Here’s some of the stories trending This Week at NASA!” Carbon Observatory’s First Data A month after its launch, the Orbiting Carbon Observatory-2, NASA’s first spacecraft dedicated to studying atmospheric carbon dioxide – has reached its final operating orbit and returned its first science data. “First light” test data were collected on August 6 as OCO-2 flew over central New Guinea -- confirming the health of the spacecraft’s science instrument’s.
An international team of sky scholars has produced new maps of the material located between the stars in the Milky Way. The results should move astronomers closer to cracking a stardust puzzle that has vexed them for nearly a century.
Researchers using a mouse model have recorded the activity of individual nerve cells in a small part of the brain that works as a “switchboard,” directing signals coming from the outside world or internal memories. Because human brain disorders typically show disturbances in that switchboard, the investigators say the work suggests new strategies in understanding and treating them.
Chemists have used click chemistry to uncover unprecedented, powerful reactivity for making new drugs, diagnostics, plastics, smart materials and many other products. The new reactions enable chemists to link molecules of their choice together using derivatives of a common commercial chemical considered essentially inert.
Scientists say seven microscopic particles collected by NASA's comet-chasing spacecraft, Stardust, appear to have originated outside our solar system. If confirmed, this would be the world's first sampling of contemporary interstellar dust.
Through commands, autonomous devices arranged selves into vast, complex shapes in the first 1,000-robot flash mob.
Scientists looking at glacier melt since 1851 didn't see a human fingerprint until about the middle of the 20th century. Even then only one-quarter of the warming wasn't from natural causes. But since 1991, about 69 percent of the rapidly increasing melt was man-made.
NASA astronaut Reid Wiseman, Expedition 40 flight engineer, has installed Capillary Channel Flow experiment hardware in the Microgravity Science Glovebox located in the Destiny laboratory of the International Space Station.
Chemical engineers have achieved a breakthrough in the race for safer, longer-lasting batteries to power the world’s automobiles, cell phones, computers and autonomous robots. Adding certain halide salts to liquid electrolytes spontaneously creates nanostructured surface coatings on a lithium battery anode. The coating hinders the development of detrimental dendritic structures that grow within the battery cell.
Children with high everyday levels of a protein released into the blood in response to infection are at greater risk of developing depression and psychosis in adulthood, according to new research that suggests a role for the immune system in mental illness.
As the oil and gas drilling technique called hydraulic fracturing proliferates, a new study on the contents of the fluids involved in the process raises concerns about several ingredients. Out of nearly 200 commonly used compounds, there’s very little known about the potential health risks of about one-third, and eight are toxic to mammals.
Chasing cancer cells with chemotherapy drugs can save lives, but there's no guarantee that the treatment will kill every runaway cancer cell in the body. What if a treatment could lure them out of hiding and eliminate them in one swift blow? A scientist has created such a therapy— a tissue-like biomaterial that attracts cancer cells, like bits of metal to a magnet, and entraps them.
This week, journalist and scientific organizations accused the EPA of attempting to muzzle its independent scientific advisers by directing them to funnel all outside requests for information through agency officials.
