Studies force new view on biology of flavonoids

03-05-2007 · EurekAlert!

Flavonoids, a group of compounds found in fruits and vegetables that had been thought to be nutritionally important for their antioxidant activity, actually have little or no value in that role. However, these same compounds may indeed benefit human health, but for reasons that are quite different - the body sees them as foreign compounds, researchers say, and through different mechanisms, they could play a role in preventing cancer or heart disease.

Fantastic Voyage: A New Nanoscale View Of The Biological World
10-06-2006 · ScienceDaily
Echoing the journey through the human body in "Fantastic Voyage," doctors might soon be able to track individual donor cells after a transplant, or to find where and how much of a cancer treatment drug there is within a cell. New technology described in a study published in the open access journal, Journal of Biology makes it possible to image and quantify molecules within individual mammalian or bacterial cells.

Study of diabetes and race reveals the imperfect science of defining ethnic groups
02-14-2007 · EurekAlert!
While previous biomedical research studies have found that genetics and race increase risk for some diseases, a new look into how researchers study genetic triggers of type 2 diabetes suggests that defining race remains an inexact science, with social and historic facts mixing with biology throughout the research process.

CMU researcher publishes anole lizard findings
03-06-2007 · EurekAlert!
Hundreds of species of anoles roam the Caribbean Islands and parts of North and South America, a highly diverse and colorful small lizard that scientists have studied in hopes of unlocking the secrets of evolution. Kirsten E. Nicholson, a Central Michigan University assistant biology professor, has just published a paper in PLoS ONE on her four-year study of Caribbean anoles that may provide a building block for future evolutionary studies.

UGA research shows rats are capable of reflecting on mental processes
03-08-2007 · EurekAlert!
A new study by researchers from the University of Georgia, just published in the journal Current Biology, shows that laboratory rats possess the ability to think about what they know or don’t know. It's the first demonstration that any non-primate knows when it doesn’t know something, and it could open the way to more in-depth studies about how animals -- and humans -- think.

Study examines correlation between race and police force size
10-01-2007 · EurekAlert!
Empirical studies have long shown that crime rate and budget alone do not account for the size of an area's police force. Police forces tend to be larger in areas where blacks comprise a larger percentage, and many sociologists have attributed this to racial attitudes, specifically the white population's perceptions of threat. A thought-provoking study is the first to empirically examine this premise.

Study led by Scripps Research scientist reveals little-known cell networks vital to circadian rhythm
05-03-2007 · EurekAlert!
In a wide-ranging systems biology study of circadian rhythm, a multi-institutional collaboration led by Scripps Research Institute Professor Steve Kay has uncovered some little-known cellular mechanisms for sustaining circadian rhythm and limiting the impact of genetic clock mutations in mammals. The new findings could have important implications for future circadian studies, and point researchers toward new ways to manipulate human circadian rhythm at the molecular level to treat diseases such as bipolar disorder.

The aye-ayes have it: The preservation of color vision in a creature of the night
09-04-2007 · EurekAlert!
Brian Verrelli and his ASU team have performed the first sweeping, genetic evolutionary study of color vision in the aye-aye (pronounced "eye-eye"), a bushy-tailed, Madagascar native primate. Verrelli, lead author George Perry, and collaborator Robert Martin's results, published in the journal Molecular Biology and Evolution, have led to some surprising conclusions on how this unusual nocturnal primate may have retained color vision function.

Gene in male fish lures females into sex
11-14-2007 · EurekAlert!
A gene has been found in male cichlid fish that evolved to lure female fish so that male cichlids can deposit sperm in the females mouths. A study in the online open-access journal BMC Biology reveals that the gene is associated with egg-like markings on the fins of cichlid fishes and uncovers the evolutionary history of these markings, which are central to the success of the fishes' exotic oral mating behavior.

Study of malaria parasite in patient blood finds distinct physiological states
11-28-2007 · EurekAlert!
In a groundbreaking study published Nov. 28 in the advance online edition of Nature, an international research team has for the first time measured which of the malaria parasite's genes are turned on or off during actual infection in humans, not in cell cultures, unearthing surprising behaviors and opening a window on the most critical aspects of parasite biology.
