Great lakes waterfowl die-offs: Finding the source

A deadly menace stalks the loons, gulls and other water birds of the Great Lakes region: Type E botulism. Cases of the disease are on the rise, and to understand die-off origin and distribution, ocean engineers are developing a novel way of tracking waterfowl carcasses to determine the source of lethal outbreaks.

The secrets of owls' near noiseless wings

Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence. A research group is working to solve the mystery of exactly how owls achieve this acoustic stealth -- work that may one day help bring "silent owl technology" to the design of aircraft, wind turbines, and submarines.

The physics of beer tapping

An old, hilarious if somewhat juvenile party trick involves covertly tapping the top of someone's newly opened beer bottle and standing back as the suds foam out onto the floor. Now researchers have produced new insight into the science behind the foaming, exploring the phenomenon of cavitation.

Even if emissions stop, carbon dioxide could warm Earth for centuries

Research suggests that even if carbon-dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years. Thus, it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.

Study identifies protein essential for immune recognition, response to viral infection

A research team has identified an immune cell protein that is critical to setting off the body's initial response against viral infection. They found that a protein called GEF-H1 is essential to the ability of macrophages -- major contributors to the innate immune system -- to respond to viral infections like influenza.

A new, flying jellyfish-like machine

Up, up in the sky: It's a bird! It's a plane! It's a . . . jellyfish? That's what researchers have built -- a small vehicle whose flying motion resembles the movements of those boneless, pulsating, water-dwelling creatures. The work demonstrates a new method of flight that could transport miniaturized future robots for surveillance, search-and-rescue, and monitoring of the atmosphere and traffic.

Gene-silencing study finds new targets for Parkinson's disease

Scientists have used RNA interference technology to reveal dozens of genes that may represent new therapeutic targets for treating Parkinson's disease. The findings also may be relevant to several diseases caused by damage to mitochondria, the biological power plants found in cells throughout the body.

X-rays reveal another feature of high-temperature superconductivity

Classical and high-temperature superconductors differ hugely in their critical temperature when they lose electrical resistance. Powerful X-rays made possible to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. This is why other scenarios must now be developed to explain high-temperature superconductivity.

How living cells solved a needle in a haystack problem to produce electrical signals

Scientists have figured out how cells do the improbable: pick the charged calcium ions out of vast sodium sea to generate electrical signals. The speed and accuracy of this selection is crucial to the beating of the heart and the flow of nerve impulses in the brain. The finding is likely to assist the development of new drugs, such as safer medications for chronic pain.

Continued increases in adhd diagnoses, treatment with meds among US children

New study reports that half of U.S. children diagnosed with ADHD received that diagnosis by age 6. The study found that an estimated two million more children in the United States (U.S.) have been diagnosed with attention-deficit/hyperactivity disorder (ADHD) between 2003-04 and 2011-12. One million more U.S. children were taking medication for ADHD between 2003-04 and 2011-12.

Meat, egg, dairy nutrient essential for brain development

Research indicates that brain cells depend on the local synthesis of asparagine to function properly. "The cells of the body can do without it because they use asparagine provided through diet. Asparagine, however, is not well transported to the brain via the blood-brain barrier," said senior co-author of the study.

Bird is the word -- plus some side dish science!

While the word "thanks" is included in our country's favorite holiday's name, we all know the real star of the day is the food. A well-known food scientist deconstructs the turkey-day menu by giving us the low-down on why all the flavors and textures go together so well and if tryptophan is the real culprit behind our post-meal food coma.

Water-based imaging maps brain neurons before surgery

Some neurosurgeons are using a new approach to visualize the brain's delicate anatomy prior to surgery. The novel technique allows neurosurgeons to see the brain's nerve connections thus preserving and protecting critical functions such as vision, speech and memory. No needles, dyes or chemicals are needed to create the radiology scan. The main imaging ingredient? Water.
