UA Grows Gourmet Mushrooms That Recycle Waste

UA plant scientists are growing gourmet mushrooms on coffee grounds, landscape waste, even pizza boxes – and reducing that waste to compost.

The University of Arizona class is called “Mushrooms, Molds and Man.” Intrigued, undergraduate Lauren Jackson decided to learn about “Kingdom Fungi” and its impact on the world.

He was hooked in a heartbeat. Barely into the course, “I just raised my hand and asked about research opportunities.” That week he started working in the lab with UA mycologist Barry Pryor. (more…)

Do peppers reduce risk of Parkinson’s?

Eating peppers — which are in the same botanical family as tobacco — may reduce the risk of Parkinson’s disease. The findings are reported in the May 9 edition of the Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society.

Nearly one million people in the United States are living with Parkinson’s disease, a neurodegenerative disorder that results from the loss of dopamine-producing brain cells. In early stages, Parkinson’s is characterized by difficulties in controlling movement. Initial symptoms include hand tremors, limb rigidity, and problems walking. As the disease progresses, cognitive problems may develop and advance into dementia. (more…)

Warm Ocean Causing Most Antarctic Ice Shelf Mass Loss

PASADENA, Calif. — Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent’s ice shelf mass loss, a new study by NASA and university researchers has found.

Scientists have studied the rates of basal melt, or the melting of the ice shelves from underneath, of individual ice shelves, the floating extensions of glaciers that empty into the sea. But this is the first comprehensive survey of all Antarctic ice shelves. The study found basal melt accounted for 55 percent of all Antarctic ice shelf mass loss from 2003 to 2008, an amount much higher than previously thought. (more…)

Berkeley Lab Researchers Report First Fully Integrated Artificial Photosynthesis Nanosystem

In the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable energy sources has been achieved. Scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have reported the first fully integrated nanosystem for artificial photosynthesis. While “artificial leaf” is the popular term for such a system, the key to this success was an “artificial forest.” (more…)

Do songbirds hold key to stuttering?

A tiny Australian songbird may hold the answer to discovering the biological source of stuttering, which affects 3 million Americans and is notoriously difficult to treat.

A team of Michigan State University scientists will investigate the brain and behavior of the zebra finch in the first in-depth study of whether stuttering stems from a lack of rhythm. (more…)

UCLA’s undergraduate researchers: ‘We’re going to have an impact on the future’

Serena Lee aspires to increase our understanding of people living with “invisible disabilities.” Amy Stuyvesant wants to figure out how changes in hurricane activity are helping or hindering the forests of Puerto Rico.

Although their subjects of their research are unrelated, these two graduating seniors share a key distinction. Thanks to the Wasserman Undergraduate Scholars Program, they are pursuing high-level research that they expect to have an impact far beyond UCLA. (more…)

Active microbes discovered far beneath seafloor in ancient ocean sediment

Microbes are living more than 500 feet beneath the seafloor in 5 million-year-old sediment, according to new findings by researchers at the University of Delaware and Woods Hole Oceanographic Institution (WHOI).

Genetic material in mud from the bottom of the ocean — called the deep biosphere —revealed an ecosystem of active bacteria, fungi and other microscopic organisms at depths deeper than a skyscraper is high. The findings were published in Nature on June 12. (more…)
