A new, cost-effective process for colouring titanium can be used in manufacturing products from sporting equipment to colour-coded nuclear waste containers.
"The new method uses an electrochemical solution to produce coloured titanium, improving on an older, time-consuming and expensive method where heat was used to develop a coloured layer," says Gregory Jerkiewicz, a professor in the Department of Chemistry.
PULLMAN, Wash.—Some baseball superstitions are accepted as cold, hard truth. But in the world of physics, the most accepted verities are subject to experimentation.
A corked bat hits the ball further? Not in Lloyd Smith's lab.
Baseballs today are livelier than in the past? See above.
Storing balls in a humidor can curb home run production? We'll grant you that one, but only because Smith has fired the balls through a cannon and measured their bounciness as they hit a bat.
An EPA study published online Monday in Environmental Health Perspectives finds that the 2008 peat bog wildfires in NC led to an increase in emergency room visits for respiratory and cardiovascular effects.
The study found a 37 percent increase in ER visits for people with symptoms of heart failure during a three day period of dense smoke exposure and the following five days.
Other findings include a 65 percent increase in visits for asthma, 73 percent increase in visits for COPD and 59 percent increase in visits for pneumonia and bronchitis.
"There's a longstanding debate about how rapidly glaciation progressed in Antarctica," said Sophie Warny, a Louisiana State University geologist who specializes in palynology (the study of fossilized pollen and spores) and led the palynological reconstruction. "We found that the fossil record was unambiguous; glacial expansion in the Antarctic Peninsula was a long, gradual process that was influenced by atmospheric, tectonic and oceanographic changes."
(Santa Barbara, Calif.) –– Physicists working at the University of California, Santa Barbara and the University of Konstanz in Germany have developed a breakthrough in the use of diamond in quantum physics, marking an important step toward quantum computing. The results are reported in this week's online edition of Nature Physics.
The physicists were able to coax the fragile quantum information contained within a single electron in diamond to move into an adjacent single nitrogen nucleus, and then back again using on-chip wiring.
Scientists have discovered fundamental steps of charging of nano-sized water droplets and unveiled the long-sought-after mechanism of hydrogen emission from irradiated water. Working together at the Georgia Institute of Technology and Tel Aviv University, scientists have discovered when the number of water molecules in a cluster exceeds 83, two excess electrons may attach to it — forming dielectrons — making it a doubly negatively charged nano droplet.
Southern California's Salton Sea, once a large natural lake fed by the Colorado River, may play an important role in the earthquake cycle of the southern San Andreas Fault and may have triggered large earthquakes in the past.
Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say—a process that feeds back into the ongoing rise in global sea levels.
Greater understanding is needed of greenhouse gas (GHG) emissions from energy use in the water sector if it is to meet sustainability goals, according to researchers at the University of East Anglia (UEA).
Nuclear power is a major component of our nation's long-term clean-energy future, but the technology has come under increased scrutiny in the wake of Japan's recent Fukushima disaster. Indeed, many nations have called for checks and "stress tests" to ensure nuclear plants are operating safely.
This spring, scientists from the California Academy of Sciences braved leeches, lionfish, whip-scorpions and a wide variety of other biting and stinging creatures to lead the most comprehensive scientific survey effort ever conducted in the Philippines, documenting both terrestrial and marine life forms from the tops of the highest mountains to the depths of the sea.
COLUMBUS, Ohio – Astronomers' research on celestial bodies may have an impact on the human body.
Ohio State University astronomers are working with medical physicists and radiation oncologists to develop a potential new radiation treatment – one that is intended to be tougher on tumors, but gentler on healthy tissue.
In studying how chemical elements emit and absorb radiation inside stars and around black holes, the astronomers discovered that heavy metals such as iron emit low-energy electrons when exposed to X-rays at specific energies.
The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton Zeilinger at the University of Vienna and the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences used a system which does not allow for entanglement, and still found results which cannot be interpreted classically. Their findings were published in the latest issue of the renowned scientific journal Nature.
Marine biologist David Wiley of the National Oceanic and Atmospheric Administration (NOAA) and others report in the latest issue of Behaviour (Volume 148, Nos. 5-6) how humpback whales in the Gulf of Maine catch prey with advanced water technology. Humpback whales (Megaptera novaeangliae) are large baleen whales (up to 14 m long) that feed on a small prey in dense concentrations, such as krill or herrings.
(Boston) – A new study conducted by a team of researchers at Boston University School of Medicine (BUSM) sheds light on a possible new approach to treat the bone marrow disease known as myelofibrosis by inhibiting an enzyme that connects extracellular fibers. The study, published online in the Journal of Biological Chemistry, was conducted under the direction of Katya Ravid, PhD, professor of medicine and biochemistry and director of the Evans Center for Interdisciplinary Biomedical Research at BUSM.
