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 […]

A Path Toward More Powerful Tabletop Accelerators

Berkley Lab researchers show how beams of various colors and phases affect plasma, finding that laser light needn’t be as precise as previously thought to drive miniature particle accelerators. Making a tabletop particle accelerator just got easier. A new study shows that certain requirements for the lasers used in an emerging type of small-area particle […]

Direct Confirmation That a Wolf-Rayet Star Died in a Type IIb Supernova

Using an innovative sky survey called the intermediate Palomar Transient Factory, scientists have the first direct confirmation that a Wolf-Rayet star died in a violent explosion known as a Type IIb supernova. Our Sun may seem pretty impressive: 330,000 times as massive as Earth, it accounts for 99.86 percent of the Solar System’s total mass; […]

Smart Window Material May Make Better Batteries

By using ultrathin sheets of smart-window material, nickel oxide, as the anode in a lithium-ion battery, researchers were able to see for first time exactly what happens when the battery’s lithium ions make contact with the nickel-oxide layer and how the resulting reaction spreads out from several different points. High-tech “smart windows,” which darken to […]
