Queen bee promiscuity boosts hive health

...ed the leading hypothesis that queens' promiscuity improves colony disease resistance by boosting the genetic diversity of their offspring, the worker bees. "This required a particularly nasty experiment, in which we inoculated colonies with the most virulent disease of honeybees that is known, the dreaded Am...

Nano-devices hold promise for early-stage cancer detection

... Research has shown that early detection of cancer improves cure and survival rates dramatically. For example, the five-year survival rate of breast cancer patients when a tumor is detected at less than two centimeters in size is 98 per cent. It is only 26 per cent when the tumor is larger than five centime...

High tech help to prevent further heart disease

...for people who have had heart surgery to see if it improves health outcomes by reducing the risk of heart problems recurring. Study leader, Professor Kerry Mummery, said post-surgery monitoring and counselling is very important to ensure that patients who have undergone heart operations change the lifestyl...

Brain protein improves stroke symptoms in rats, even when injected after 3 days

A protein naturally occurring in the brain improves recovery from stroke when injected up to three days after the onset of the stroke, and could be used as an effective stroke drug. A study in rats published today in the open access journal BMC Biology shows that an injection of Granulocyte-Colony Sti...

New technology used to construct the first map of structural variation in the human genome

...ing) regions of the human genome and substantially improves resolution over previous arrays. The array was employed in a process known as comparative genomic hybridization (CGH), which involves tagging genomic DNA from two individuals and then co-hybridizing it to the array. Data from the array were assesse...

Paying attention sets off symphony of cell synchronization

... attention operates. The mystery of how attention improves the perception of incoming sensory stimulation has been a long-time concern of scientists. One hypothesis is that when you pay attention neurons produce stronger brain activity, as if the stimulus itself was stronger. That would mean that paying atte...

Protowings may have helped bird ancestors cover rough terrain

...wings in a characteristic way while running, which improves their ability to climb steep slopes and even vertical surfaces. Dial and colleagues have named this form of locomotion "wing-assisted Iincline running" (WAIR). After they are able to fly, chukars often use WAIR in preference to flying to gain elevate...

3-D ultrasound scanner could guide robotic surgeries

...be cancer. As artificial intelligence technology improves in the coming decades, the scanner might even be able to guide surgical robots without the help of a surgeon, the researchers said. The 3-D ultrasound probe has yet to be tested in human patients, Smith said, but he added that his team believes the...

Serotonin, acting in a specific brain region, promotes sleep in fruit flies

..., as well as the quality, of sleep. Serotonin even improves sleep in certain mutant flies that normally sleep less or have fragmented sleep, suggesting that serotonin treatment can overcome some deficits caused by other sleep problems. The researchers also identified a serotonin receptor that affects sleep, a...

Reversing 'hibernating' heart muscle focus of UB researchers

...estoring blood flow to these "hibernating" regions improves function and a patient's prognosis, cells in the left ventricle (the heart's main pumping chamber) often remain chronically dysfunctional and do not return to normal. The reasons for this remain unclear, researchers say, but in most circumstances d...

Methane-belching bugs inspire a new theory of the origin of life on Earth

...es. This new, "thermodynamic" theory of evolution improves upon both previous theories by proposing a central role for energy conservation during early evolution, based on a simple three-step biochemical mechanism. Their results also provide insights into the evolution of the microbial production of methane...

Compound in dairy products targets diabetes

Adult stem cell research at UB targets damaged hearts

However, these results also found that cells in the left ventricle, the heart's main pumping chamber, often do not return to normal, leaving the heart compromised. The new research is headed by Te-Chung Lee, Ph.D., associate professor of...
