CORVALLIS, Ore. - Recovering populations of killer whales, sea lions and harbor seals on the West Coast have dramatically increased their consumption of chinook salmon in the last 40 years, which may now exceed the combined harvest by commercial and recreational fisheries, a new study finds.
CHAMPAIGN, Ill. -- Centuries of study have yielded many theories about how the brain gives rise to human intelligence. Some neuroscientists think intelligence springs from a single region or neural network. Others argue that metabolism or the efficiency with which brain cells make use of essential resources are key.
WOODS HOLE, Mass.--Using a simple "mirror trick" and not-so-simple computational analysis, scientists affiliated with the Marine Biological Laboratory (MBL) have considerably improved the speed, efficiency, and resolution of a light-sheet microscope, with broad applications for enhanced imaging of live cells and embryos.
Slight changes to the system for allocating deceased-donor kidneys could result in higher rates of organ procurement and lead to more kidney transplants across the country, according to new research co-authored by an Indiana University Kelley School of Business professor.
"Any increase in supply will result in saved lives," said Rodney P. Parker, an associate professor of operations management at Kelley. "The lists of patients awaiting a kidney transplantation are lengthy and growing. Many of these patients undergo expensive and inconvenient dialysis treatment while waiting."
URBANA, Ill. - Handling a poorly timed tantrum from a toddler--such as in the middle of the grocery store--is never an easy task. It could serve as a teachable moment for a mom to help her child learn to manage his own emotions. After all, research shows that how parents react in these types of situations can play an important role in a child's emotional development.
But how does that child's negative behavior -- that tantrum in the frozen food aisle -- affect a mother's own stress level, and therefore, her ability to parent?
URBANA, Ill. - Spending time together with family may help strengthen the family bond, but new research from the University of Illinois shows that specifically spending time outside in nature--even just a 20-minute walk--together can help family members get along even better.
Childhood obesity is often attributed to a lack of exercise. So what about sports among elementary school students? A team from the Technical University of Munich (TUM) pursued this question and collected the results of fitness tests for first-year students over a period of one decade. Their study shows that students did not lose their strength. Speed or balance even increased over the time of ten years. One change was in the boys, whose endurance decreased compared to the girls of the same age.
U of G scientists have made a discovery that could reduce the spread of cancer by hindering a protein that binds cancer cells together and allows them to invade tissues.
The groundbreaking study identified a protein, known as cadherin-22, as a potential factor in cancer metastasis, or spread, and showed that hindering it decreased the adhesion and invasion rate of breast and brain cancer cells by up to 90 per cent.
Appraisal of employees often gets a bad press, but recent research suggests if it involves frequent feedback between the formal appraisal and good prior planning and communication of standards then it can be successful and appreciated by employees.
Background: Enterococcus faecalis 2001 is a probiotic lactic acid bacterium and has been used as a biological response modifier (BRM). From physiological limitation of bacterial preservation in storage and safety, the live E. faecalis 2001 has been heat-treated and the BRM components containing high level of β-glucan, named EF-2001, were prepared. Method: The heat-treated EF-2001 has been examined for the antioxidative potential for radical scavenging and anti-tumor activities as well as immune-enhancing response in mice.
