New study reveals components of cocoa may enhance the appearance of the skin

...esearch just published in the Journal of Nutrition reveals the potential benefits of consuming flavanol-rich cocoa and how it might actually benefit skin from the inside out. Researchers found that certain components in cocoa may actually help improve the appearance of women's skin ?increasing hydration, de...

HIV infection requires an accomplice: B cells with special protein direct HIV to T cells

...molecule on the surface of B cells, a finding that reveals yet another pathway the virus uses in its insidious attack on the immune system, University of Pittsburgh researchers will report at the XVI International AIDS Conference (AIDS 2006). "The research supports a new role for B cells in the development...

Study identifies new role for breast cancer susceptibility gene

...cet of the breast cancer susceptibility gene BRCA1 reveals a mechanism linking mutation of BRCA1 to formation of large blood vessels needed to support cancer progression. The findings demonstrate that, in addition to an impaired DNA damage response associated with cancer initiation, mutation of BRCA1 is also...

Genetic snooze button governs timing of spring flowers

...iate flowering in the spring. What they have found reveals some of the complex interplay of genes and environment and provides hints that, one day, it may be possible to exert precise control over flowering, a process essential for plant reproduction and fruiting and that has enormous implications for agricu...

Researchers attack tumor cells by exploiting dependency on sugar metabolism

...w study published in the June issue of Cancer Cell reveals a functional connection between carbohydrate-driven energy production and tumor maintenance. Importantly, the results suggest that inhibition of a specific aspect of glucose metabolism may represent an attractive and potentially well-tolerated approa...

Triple threat polymer captures and releases

...eterogeneous coating that, upon close examination, reveals treacherous nanometer-sized terrain composed of mountains and valleys, ranging from hard to soft, hydrophilic to hydrophobic. The complex surface that is created makes it difficult for marine organisms to establish a toehold. Her laboratory has prod...

Corals switch skeleton material as seawater changes

...orm of calcium carbonate, he said, the team's work reveals that corals are far more flexible and able to vary at least a portion of their skeleton to growth favored by seawater chemistry. He postulates that this "mineralogical flexibility" provides corals with an "evolutionary advantage," as it would take mo...

Drug dials down the energy within cells, UM researchers find

... ATP, and that's fatal," Glick said. "Our new work reveals the mechanism by which Bz-423 inhibits the enzyme while still allowing it to function. This is important because it suggests principles that may be useful for targeting other bioenergetic pathways. Now we have some rules that we can apply to be able ...

Wasps queue for top job

...y the Natural Environment Research Council (NERC), reveals that those higher up the chain and therefore with a greater chance of being the next in line to breed are much lazier than their lower-ranked nest-mates: rather than use up their energy in foraging to feed the queen's larvae, high-rankers sit tight o...

What controls stickiness of 'smart' chromosomal glue

... miscarriages and mental retardation. The new work reveals how gluelike protein complexes release pairs of chromosomes at precisely the moment of meiosis ?the specialized cell division process that produces sperm and eggs ?enabling them to separate properly. The researchers, led by Howard Hughes Medical In...

Researchers discover how bacteria sense their environments

... issue of Nature Structural and Molecular Biology, reveals that receptors assemble into a kind of cooperative lattice on a bacterium's surface to amplify infinitesimal changes in the environment and kick off processes that lead to specific responses within the cell. "Bacteria sense a lot of different things...

Hair samples show babies can be exposed to 'crystal meth' while in the womb

...thamphetamine or "crystal meth" while in the womb, reveals an analysis of hair samples, published ahead of print in the Fetal and Neonatal Edition of Archives of Disease in Childhood. Unlike hair, the most commonly used detection methods (blood and urine), cannot register long term use, nor can they always...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

...iterature, Science, and the Arts. "This finding reveals a type of brain Morse code for pleasure," says Berridge. "The faster these neurons fire, the more pleasant the taste seems to become. The hardest test for a pleasure code is whether the brain signal can track the change from nasty to nice. The amazin...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...g normal copies of the gene. "We think our study reveals a direct weight management pathway," says Michael Wolfgang, Ph.D., a postdoctoral fellow in the Department of Biological Chemistry at The Johns Hopkins University School of Medicine and an author of the report. "CPT1c seems to allow the body to resp...

Ohio University researchers discover evolutionary oddity in flamingos

...discovery by a team of Ohio University researchers reveals an anatomical oddity that helps flamingos eat: erectile tissue. Flamingos are known for their peculiar feeding behavior. While standing in shallow water, they bend their necks, tilt their bills upside down in the water and swish their heads from sid...

How nature tinkers with the cellular clock

...lished in this week's online issue of Nature, also reveals that although most components of the cell cycle have been conserved over one billion years, the temporal regulation of this process has evolved remarkably fast. The cell cycle is so fundamental for a cell that its machinery has been almost entirely...

Viral marker of human migration suspect

...n size followed by a rapid increase, a closer look reveals that while human populations started to expand considerably about 50,000 years back, the viral population expanded only in the last few hundred years. "Besides, there are several instances of one population group harboring a subtype typically asso...

Chemotherapy temporarily affects the structures of the human brain

... journal of the American Cancer Society, the study reveals that within 12 months of receiving adjuvant chemotherapy, significant regions of the brain associated with memory, analysis and other cognitive functions were significantly smaller in breast cancer patients who received chemotherapy than those who di...

Long-term cancer risk follows stem cell transplant recipients

... journal of the American Cancer Society, the study reveals that within 10 years of an allogeneic HSCT, the relative risk of a second, solid cancer is almost twice that of the general population. In addition, cancer risk almost quadruples for patients who were over 40 years old at the time of transplant or fo...

New target for cancer therapy identified

...human cells," Associate Professor Liu said. "This reveals an important mechanism for developing anti-cancer agents that mimic these proteins and thereby inhibit the production of telomerase. " ...
