Noise echoes in cell communications

.... Unlike a physics experiment that can produce the same result after various attempts, in biology, one particular experiment can yield a multitude of outcomes. This randomness, however, isn't problematic, but a necessary function for survival. Until now, the role of randomness in sustaining life has be...

BMI not accurate indicator of body fat

Sandia researchers take new approach to studying how cells respond to pathogens

...d not all cells are exposed to the pathogen at the same time," Singh says. "We wanted to look at cells in the same life cycle and same infectious state. This can only be done cell by cell. We also want to study popu...

2 brains -- 1 thought

Out-of-body experiences may be caused by arousal system disturbances in brain

...h an out-of-body experience could show many of the same prominent features of a near death experience. Near death experiences are responses to a life-threatening crisis, and are characterized by a combination of disassociation from the physical body, euphoria and transcendental or mystical elements.

Transfusion expert urges wider use of filtered blood

...that saves money and is better for patients at the same time. This is as basic as washing your hands before conducting a physical examination of a patient," Blumberg said. "But despite much scientific evidence that supports this notion, millions of people today are still receiving transfusions that might ...

Gut research yields new anti-cancer approach

... that PPARgamma inhibitors act through some of the same mechanisms as the blockbuster chemotherapy Taxol, but with key differences. While studying whether compounds known to affect PPARgamma could play a role in inflammatory bowel diseases, a team at the University of Rochester Medical Center found that ...

Gene tests and brain imaging reveal early dementia

"It's surprisingly difficult to diagnose Alzheimer's with any certainty, but things are made easier if you know who runs the greatest risk," she says. "If g...

In obesity, brain becomes 'unaware' of fat

Despite their heft, many dinosaurs had surprisingly tiny genomes

..., Organ and Edwards are the first to show that the same applies to the bone cells called osteocytes. These cells reside in individual lacunae, small pockets inside bone tissue. This uniquely durable cellular housing allowed the scientists to look back in time at the size of 31 extinct species' genomes:...

The number of mitochondria within muscle largely determines its metabolic capacity. The mitochondrial composition of fibers in different muscles corresponds to the jobs that they do, ...

Nanotextured implant materials: blending in, not fighting back

As a result, there is an increased probability that high-ranking males, with desirable social and physical attributes, will mate with the fertile females.
