This study was published in the December 1, 2004, issue of the Journal of Agriculture and Food Chemistry. * Heart disease. Antioxidants found in apple extracts could potentially lowe...

To sea or not to sea: When it comes to salmon sex, size sometimes doesn't matter

...awn, instead straying to some other waterway. The process of straying is entirely mysterious, Quinn says. Do strays identify the home stream but then go elsewhere? Do they have poorer memory or sensory capabilities and so stray out of ignorance? Or are there other factors involved? "These strays are not me...

Putting ecology back into river restoration

...ll-or-nothing, single endpoint, but as an adaptive process where small improvements build up and lessons are learned from any failures. The third criteria for successful river restoration is to create hydrological, geomorphological and ecological conditions that allow the river to be a resilient, self-susta...

OneWorld Health drug receives 'Orphan' designation from U.S. and European regulatory agencies

... need is greatest. It will begin the drug approval process with the FDA and/or the EMEA next year. "We are pleased with the swift, positive responses by the FDA and EMEA agencies," said Victoria Hale, Ph.D., CEO and Founder of OneWorld Health. "By meeting the rigorous standards of either agency, we will be ...

Confocal imaging promises early detection of skin cancer

...blee, coordinator of the IST project EDISCIM. “The process involves visits to a general practitioner and a hospital specialist. With our new system, we hope to replace these visits with just one visit and by detecting skin cancer as early as possible, to offer patients the most complete treatment.?/p> Do...

Signs of aging: Scientists evaluate genes associated with longevity

...uld be those most critical to the vital biological process of aging. In addition, they reasoned that some of the genes that were differentially expressed between daf-2 mutants and controls would also be associated with longevity. Most strikingly, the scientists observed that during the early and mid-life ad...

After a time-shift, mixed signals from the circadian clock

...s now report findings that suggest this adaptation process does not necessarily involve a gradual and synchronous adaptation by the neurons that comprise the central circadian clock--rather, that different components of the clock tend to adapt to a shifted light schedule at two different speeds. The work is...

Basis for DNA ejection from single phage particles

...A was measured at different stages of the ejection process after being stretched by applied hydrodynamic flow. The study demonstrated that DNA release is not an all-or-none process, but rather is unexpectedly complex. DNA release occurred at a very high rate, reaching 75,000 base pairs of DNA/sec, but in a s...

Researchers make surprise discovery that some neurons can transmit three signals at once

...e neurotransmitters can produce depolarizations, a process that normally can only be achieved by excitatory transmitters. It is not yet known how long the cells retain this unique capacity, for how long the neurons are able to release all three neurotransmitters or what causes the cells to stop releasing gl...

Researchers develop assay that could be applied to drug screening

...ey invaginated and detected membrane scission, the process by which a coated pit is converted into a clathrin coated vesicle. In further experiments, the researchers showed how proteins linked to the actin framework of the cell are brought to sites of coated pit. Actin is a protein polymer used by cells both...

Conserved amino acids play both structural and mechanistic roles in sandwich-like protein

Doing a spin with DNA

The enzyme releases the torsion from the DNA as follows: The enzyme surrounds the double-stranded DNA like a clamp and then temporarily c...

Stanford gut check shows diversity of intestinal ecosystem

The latter will allow them to analyze samples much more quickly. They have been working with biochemistry professor P...

Unchecked DNA replication drives earliest steps toward cancer

Discovery clarifies role of peptide in biological clock

...s pacemakers," he said. It is surprising that the process is regulated by a peptide, usually a slow signaling agent, rather than a neurotransmitter, associated with fast events, Herzog said. "We're trying to understand the mechanics of how the system synchronizes and the secondary messenger systems as well...
