Determining Radiation Safety for Sunken-Ship Archaeology

A team of researchers at the National Oceanic and Atmospheric Administration rediscovered the scuttled U.S.S. Independence, determining the radiation risk of exploring the underwater aircraft carrier. About 42 miles southwest of San Francisco and 2,600 feet underwater sits the U.S.S. Independence, a bombed-out relic from World War II. The aircraft carrier was a target ship […]

Proper Copper Levels Essential to Spontaneous Neural Activity

A new study from the Berkeley Lab reveals that proper copper levels are essential to the health of a brain at rest and suggests that mismanagement of copper in the brain linked to Alzheimer’s and other neurological disorders can also contribute to misregulation of signaling in cell−to-cell communications. In recent years it has been established […]

Astrophysicists Reveal An Unusual Death for Ancient Stars

New supercomputer simulations show that non-rotating supermassive primordial stars can die as highly energetic thermonuclear supernovae powered by explosive helium burning, releasing about 10,000 times the energy of a Type Ia supernova and leaving no compact remnant. Certain primordial stars—those between 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died […]

New Results Pave the Way for Closed Loop Biofuel Refineries

Researchers have developed “bionic liquids” from lignin and hemicellulose, two by-products of biofuel production from biorefineries, paving the way closed loop biofuel refineries. While the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels, an even more promising candidate is on the […]
