Ancestral Fungus May Have Influenced Coal Formation
2012-07-01 10:03:04

Brett Smith for redOrbit.com - Your Universe Online A new study suggests that the evolution of a fungus known as white rot may have ended a 60-million-year-long period responsible for coal deposition. Coal deposits that occurred because of the Carboniferous Period, which ended about 300 million years ago, have fueled about 50 percent of U.S. electric power generation as recently as 2010. The research, presented online in the June 29 edition of Science, points to the evolution of...

Drugs target Nox2 enzyme directly instead of acting as antioxidants Scientists at Emory University School of Medicine have identified a new type of anti-inflammatory compound that may be useful in treating a wide range of conditions, including neurodegenerative and autoimmune diseases. These compounds inhibit the enzyme Nox2, part of a family of enzymes responsible for producing reactive oxygen species (ROS). "Nox2 inhibitors could be valuable with many conditions where inflammation...

International collaboration puts molecular face on enzyme family that allows plants to adjust quickly to herbivore attack or changes in growing conditions Science has known about plant hormones since Charles Darwin experimented with plant shoots and showed that the shoots bend toward the light as long as their tips, which are secreting a growth hormone, aren´t cut off. But it is only recently that scientists have begun to put a molecular face on the biochemical systems that...

Nanotechnology Harnesses The Power Of Fireflies
2012-06-17 03:00:18

What do fireflies, nanorods, and Christmas lights have in common? Someday, consumers may be able to purchase multicolor strings of light that don´t need electricity or batteries to glow.  Scientists at Syracuse University found a new way to harness the natural light produced by fireflies (called bioluminescence) using nanoscience. Their breakthrough produces a system that is 20 to 30 times more efficient than those produced during previous experiments. It´s all about the...

The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes the world's first "electrified snail," which now joins the menagerie of cockroaches, rats, rabbits and other animals previously implanted with biofuel cells that generate electricity – perhaps for future spy cameras, eavesdropping microphones and other electronics – from natural sugar in their bodies. Based on a report by Evgeny Katz, Ph.D.,...

A long-used anti-cancer drug could be a starting point to develop new treatments for the incurable nerve disease known as Lou Gehrig's disease or amyotrophic lateral sclerosis (ALS), scientists are reporting. Their research showing how the drug prevents clumping of an enzyme linked to ALS appears in the Journal of the American Chemical Society. Lucia Banci, Ivano Bertini and colleagues explain that ALS causes a progressive loss of muscle control as the nerves that control body movements...
