Salty oceans provide early warning for climate change

...iness in South African waters could be linked to a slowing down of the North Atlantic circulation. Models and data both indicate that these changes in ocean circulation occur over very short time-scales, usually in less than a decade or two. Ocean water can’t possibly travel this fast (it takes nearly a c...

Undergraduate research shows leaderless honeybee organizing

...changing her behavior -- reducing her food intake, slowing egg laying and becoming more active. At this point, the workers begin to send a second signal that researchers call “worker piping” at a fevered pitch. Piping, which consists of bees making contact and vibrating their wing muscles rapidly, appears to...

Weizmann Institute scientists develop a general 'control switch' for protein activity

... controlling these applications – strengthening or slowing the rate of protein activity in an immediate and reversible manner – can be of great value....

Confirmed -- deforestation plays critical climate change role

...s that while tropical deforestation will continue, slowing the amount of clearing will make significant impacts. "If by 2050 we slow deforestation by 50 per cent from current levels, with the aim of stopping deforestation when we have 50 per cent of the world’s tropical forests remaining, this would save the...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

... muscles of mice with Duchenne muscular dystrophy, slowing the disease-associated muscle wasting. The authors caution that they have not yet found a way to tweak the switch, known as PGC-1alpha, in humans. “I think that if we could elevate the levels of PGC-1alpha in the muscles of patients with Duchenne ...

Researchers find link between food odors and lifespan in fruit flies

Aspirin discovery may improve cancer treatments

...hesis," Professor Williams said. "Inhibiting or slowing down protein synthesis reduces the accumulation of incorrectly folded proteins in cells, which reduces cellular stress and allows protein synthesis to return to normal." Under conditions of cellular stress, eIF2Ą is phosphorylated by a group of ...

Anti-wrinkle compound causes pathological reaction in skin cells

...ion of DMAE, the researchers observed an important slowing down of cell division—sometimes coming to a complete stop, the inhibition of certain metabolic reactions, and the death of a significant percentage of fibroblasts. The mortality rate of fibroblasts, which varied according to DMAE concentration, was a...

Molecular motors and brakes work together in cells

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...and completely prevents flu symptoms developing by slowing influenza infection rates to such an extent that the harmful infection becomes a vaccine against that very form of influenza. It can also counter an actual infection and offer protection if given up to 24 hours after first infection (and possibly lon...

Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...ge to not shivering when diving. In addition to slowing metabolism and generally reducing the need for oxygen, the researchers found that the seal's brain may cool about 3° C during the dives. The cooler brain requires less energy and oxygen and reduces the chance of damage caused by hypoxia, Folkow expla...

Plant-derived molecules, genetic manipulation point to future chemoprevention methods

...molecules have demonstrated their effectiveness in slowing the growth of lung cancer tumors, a research team from Dartmouth University has found. Following up on previous work showing strong links between inflammation and the development of cancer, Karen Liby, Ph.D., a postdoctoral fellow, and her collea...

Researchers image molecular motor structural changes

... kinesin activity might be a potential approach to slowing the uncontrolled cell division of cancer. For example, the drug Taxol, which is used to treat breast and ovarian cancers, works by stabilizing microtubules. But the problem with using Taxol as a general inhibitor of cell division is that it works on ...

Study defines effective microbicide design for HIV/AIDS prevention

...semen into body tissues, Geonnotti explained. That slowing would give the HIV-neutralizing ingredient in the microbicide layer, as well as the body's natural defenses against HIV, more time to work. If left untreated, HIV attacks a person's immune system and can progress to AIDS, acquired immune deficiency s...

Diabetes research takes wing thanks to long-lived fruit fly

...mount of insulin, preparing the body for stress by slowing its metabolism and limiting its energy output. It might also offer a new way to control insulin production. Like JNK, the insulin receptor is also involved in determining life span. Caloric restriction ?limiting the calories an organism ingests ?gen...

Nanotechnology being used to improve biocompatibility of human prosthetics and implants

...world age the current trend is that people are not slowing down in their later years. The desire for increased activity among the elderly also means increased demands on medical researchers to come up with better ways to keep them active. In the fields of implants and prosthetics calcium phosphate (CP) coati...

New research: Soy germ isoflavones reduce bone loss

... isoflavones (84 and 126 mg SoyLife® EXTRA/day) in slowing bone loss in 90 early postmenopausal Chinese women. Isoflavones are found predominately in soy products. Their structure and functions are similar to estrogen, and observational studies suggest that higher intakes of soy and soy products may lower th...

Science finds new fix for UV-damaged skin in arthritis treatment

... they knew that niacinamide had similar effects on slowing down pigment production and hypothesized that the two might work better together. The panel reviewed data from three studies involving the n-acetyl glucosamine /niacinamide formulation. Tissue studies showed a reduction in melanin and an increase i...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

...ancing measures could be particularly effective in slowing pandemic flu spread in the U.S.," added Longini. The results show that advance preparation of a modestly effective vaccine in large quantities appears to be preferable to waiting for the development of a well-matched vaccine that may not become avai...
