Studies force new view on biology of flavonoids

...ting cancer or heart disease. Based on this new view of how flavonoids work, a relatively modest intake of them ?the amount you might find in a healthy diet with five to nine servings of fruits and vegetables ?is sufficient. Large doses taken via dietary supplements might do no additional good; an appl...

Paper challenges 1491 Amazonian population theories

... many conservationists take to be ‘natural.' This view has become fashionable among many archaeologists a... that the Amazonia has been disturbed and that the view of the Amazonian rainforest as a built landscape is gaining momentum. There are extremes at either e...

Horse genome assembled

...r SNPs, will provide scientists with a genome-wide view of genetic variability in horses and help them identify the genetic contributions to physical and behavioral differences, as well as to disease susceptibility. There are more than 80 known genetic conditions in horses that are genetically similar to ...

New study sheds light on 'dark states' in DNA

...sipation, and this is a major correction in how we view DNA photostability." Until now, the proposed dark energy state of DNA was a little like the dark matter in the universe ?there was no direct way of probing it. The Ohio State chemists used a technique called transient absorption, which is based on ...

Stability of mRNA/DNA and DNA/DNA duplexes modulates mRNA transcription

...nov. "Until now we have pretty much simplified our view of DNA helix as a Lego combination of four different pieces, which encodes genetic information and contain patterns, recognized by DNA binding proteins. However, nucleic acids are real molecules with defined physical characteristics, which can influe...

Inflammation may play role in metastasis of prostate cancer

...astatic program. The new results also support the view that RANK ligand is a general promoter of prostate, and possibly breast, cancer metastasis. "Maspin is a very potent inhibitor of metastasis; in a patient with metastasis, cells have found a way to turn off Maspin, which may depend on invasion of t...

Scientists map key landmarks in human genome

...ex.html . "This study presents the first global view of human nucleosome positioning," said Fisher. Although analyses of this type had been pioneered in simpler organisms such as yeast, those approaches were not feasible when applied to the massively larger and more complex human genome. The new tec...

Sleep enforces the temporal sequence in memory

...niversity of Lübeck have confirmed the widely held view that long-term memories are formed particularly during sleep, and that this process relies on the brain replaying recently encoded experiences during the night. The same research group now provides evidence that sleep not only strengthens the content...

Studies yield insight into the numerical brain

...ects whose brains were being scanned using fMRI to view consecutive numbers presented on a screen that represented either the same or different quantities. Crucially, the numbers were also presented either as two words (e.g., two or eight), two digits (e.g., 2 or 8), or a mixed notation (two and 8). The...

Antibody signal may redirect inflammation to fuel cancer

...s a critical and surprising detail to the emerging view that inflammation, usually a helpful response to invading pathogens, can become misdirected and fuel cancer. The new research was presented today (February 19) by UCSF scientist Lisa M. Coussens, PhD, at the annual meeting of the American Associa...

New test for most virulent HPV strains under study

... Pap smears or colposcopy, in which physicians can view the cervix and freeze, excise or vaporize significant cellular changes. For more information about the study, call Study Coordinator Ansley Dennis in Dr. Ferris?office at 706-721-2535. ...

Do you hear what i see?

...atory at McGill University. "The textbook-standard view of sensory systems as isolated from one another is no longer tenable." Zatorre did not participate in the study. Kayser’s team used functional magnetic resonance imaging to draw a map of 11 small, tightly packed fields in the monkeys?auditory cort...

Cells use 'noise' to make cell-fate decisions

... housed. "Our research provides a systems-level view of how gene circuits work as a whole," he said. Dr. Süel said the next step in his research would be to uncover the theoretical design principles of genetic circuits and what role interactions between distinct circuits play in regulating complex b...

Microfluidic chip helps solve cellular mating puzzle

...ched to a microscope, the researchers were able to view a microfluidic chip and study the mating behavior of yeast cells in response to different concentrations of pheromone in the presence or absence of Kss1. They were surprised to find that this second MAPK, thought to be relatively unimportant, actuall...

Stem cell identity in culture may strongly depend on the cellular microenvironment

...servations are in line with the currently emerging view that differentiation is context dependent rather than a pre-programmed attribute of the cells. In practice, this work provide a rationale to research strategies that aim to increase the efficiency of stem cell-related culture methods and, perhaps, ev...

Fish can determine their social rank by observation alone, study finds

...milar, right down to the eyebar. From the point of view of the bystander, therefore, each rival looked like a winner. Using a video camera, researchers recorded which rival the bystander approached first, and the overall time he spent next to each of them. "Previous experiments in A. burtoni and other...

Satellites shed light on global warming

... unrivalled accuracy on account of its unique dual view of the Earth’s surface, whereby each part of the surface is viewed twice, through two different atmospheric paths," Llewellyn-Jones added. "This not only enables scientists to correct for the effects of dust and haze, which degrade measurements of su...

Breathing easy: When it comes to oxygen, a bug's life is full of it

... “flying?snakes. He has used synchrotron x-rays to view working tracheal tubes and air sacs in living insects that give further clues to how the system works. Insects employ autoventilation (using wings or legs to pump air through the body), abdominal pumping (using the muscles in the abdomen to pump air)...

Research project tackles 'regeneration' gap

...project is "bold" because it takes a comprehensive view of regenerative medicine, according to Arlene Y. Chiu, Ph.D., director for scientific activities at the California Institute for Regenerative Medicine. "We are all excited by the great potential of stem cells to repair damage and return function,"...
