Putting feelings into words produces therapeutic effects in the brain

...t moment, without distraction — seems to produce a variety of health benefits. When people see a photograp... mindfulness meditation is effective in reducing a variety of chronic pain conditions, skin disease, stress-related health conditions and a variety of other ai...

Modified mushrooms may yield human drugs

...genetically modify Agaricus bisporus -- the button variety of mushroom, which is the predominant edible species worldwide. One application of their technology is the use of transgenic mushrooms as factories for producing therapeutic proteins, such as vaccines, monoclonal antibodies, and hormones like insulin...

St. Jude study shows genes play an unexpected role in their own activation

...ecule called cAMP, which acts as a messenger for a variety of stimuli including hormones and nerve-signaling molecules called neurotransmitters. The St. Jude team showed that each gene that responds to CREB chooses which co-factors, or helper molecules, CREB uses to activate that gene. This finding adds ...

'Smart' mice teach scientists about learning process, brain disorders

...rgets that hold promise for future treatments of a variety of cognitive disorders," he said. The researchers also recorded nerve-cell firings in the hippocampus, an area of the brain associated with learning. Hippocampus slices from the knock-out mice responded much more strongly to an electrical stimula...

New research shows sharks use their noses and bodies to locate smells

...s no directional properties, so animals must use a variety of senses to get the directional information for a smell," said Jelle Atema, professor of biology at Boston University and study co-author. The new study examined the contribution of the olfactory system, the lateral line, and vision in odor sourc...

New study suggests potential for a broadly-protective HIV vaccine

...effectiveness in neutralizing the infectivity of a variety of HIV-1 strains. Antibodies produced as a result of immunization neutralized all 48 strains of HIV-1 tested. The results are encouraging for vaccine development, because they showed that it is possible to elicit a broad-spectrum antibody response....

More recycling on the farm could reduce environmental problems

...switch to regenerative agriculture would involve a variety of changes, including reduced use of inorganic fertilizers and more on-farm energy generation from wind and fermentation of biosolids. It would also reduce overcropping and leakage from manure storage that contaminates groundwater. Yet despite simila...

Technique monitors thousands of molecules simultaneously

...rochemically addressable chip. In this way, a wide variety of molecules can be generated and then probed for their biological behavior in real-time," said Moeller. "It's a tool, still being developed, to map receptors. We're right at the cusp of things." Moeller published on the technology in a recent arti...

Amphibians in losing race with environmental change

...der today's conditions may subject amphibians to a variety of damaging agents." Natural selection and species adaptation may, in time, allow amphibians to react to and recover from the new environmental insults, Blaustein said, if they don't go extinct first. But evolution is an erratic, often slow and...

Climate change impacts stream life

...Welsh streams and rivers, affecting the number and variety of some of their smallest animals, a major Cardiff University study has found. Rivers and streams are key ecosystems for many aquatic species and form important links with surrounding habitats, yet little emphasis has been given so far to the ecolo...

Novel system developed to turn data into real-time, interactive 3-D images

...the ability of physicians to make diagnoses from a variety of imaging techniques," Blank says. "Our approach allows the physician to rapidly and efficiently study hundreds of images at once by turning the data into a three-dimensional (3-D) object that appears to float in midair." The technology will all...

Master regulatory gene of epithelial stem cells identified

...place the tissue it sloughs off is controlled by a variety of genes. A new study from Harvard Medical School published in the May 4 issue of Cell, however, identifies a "master regulator" of this regeneration process not only for skin, but for many epithelial tissues including breast, prostate, and urogenita...

Alien plants attack using 'resource conservation' as weapon, researchers say

...es typically involve early detection followed by a variety of removal methods, such as weed-whacking or intro... potential invaders, he said. Scientists look at a variety of factors to assess which plants should be included on the lists, but models for determining which ...

Simple home spit test to spot deadly pre-eclampsia

...n addition, high blood pressure can be caused by a variety of factors other than pre-eclampsia, and even when a woman develops pre-eclampsia, problems with high blood pressure may not occur until the latter stages. The new test works by monitoring levels of urate, a salt of uric acid, increased levels of...

Targeting sugar on blood vessels may inhibit cancer growth

...th factor, or others that impact angiogenesis in a variety of carcinomas ?this therapy could be used to inhibit cancer growth and metastasis with fewer side effects....

DNA repair proteins monitored at double-strand break

...es ataxia-teleangiectasia, a disease that causes a variety of debilitating problems, such as neurodegeneration, cancer and sensitivity to irradiation leading to double-strand breaks that are not repaired," Kastan said. "And a lack of NBS1 causes Nijmegen breakage syndrome, another disease that leaves its vic...

World's leading scientists announce creation of 'Encyclopedia of Life'

...e all can increase our appreciation of the immense variety of life, the challenges to it, and ways to conserve biodiversity. The Encyclopedia of Life will ultimately make high-quality, well-organized information available on an unprecedented level. Even five years ago, we could not create such a resource, b...

Tissue engineered scaffolding allows reproduction of cartilage tissue

...affolding may hold great promise for the future. A variety of applications are possible for the engineering of cartilage tissue as the shape and porosity can be altered to suit the type of tissue required." ...

Parasites' impact goes beyond host to affect ecosystem

...y are an important food and habitat resource for a variety of organisms. Over the three-and-a-half-week field experiment, ephemeral algae increased 186 percent in the no-snails control cage and 59 percent in the cage of infected snails; it decreased by six percent in the uninfected snails treatment. "Wha...

DNA-damage test could aid drug development

...assay in rats and other organisms, and with a wide variety of other toxic chemicals. "This research is the first stage in a new type of clinical drug toxicity test," says Lodish. "And although we haven't done it, you may be able to extend the technique to humans. Humans are the gold standard in that one w...
