Noise echoes in cell communications

...clarifying the JPG image. The findings could have numerous applications ?most obviously in treating hearing loss by artificially increasing the amount of noise in the cochlea of the inner ear, perhaps by an implanted device. Hong, Saidel and Martin applied this principle of noise to another process called...

Scientists genetically engineer tomatoes with enhanced folate content

...her developmental problems in children, as well as numerous health issues in adults, such as anemia. "Folate deficiency is a major nutritional deficiency, especially in the developing world," said Parag Chitnis, program director in the National Science Foundation's Division of Molecular and Cellular Biosci...

Study shows isolation of stem cells may lead to a treatment for hearing loss

...ions and potentially lead to new therapies for the numerous individuals that are going to suffer from noise-induced hearing loss in the near future. ...

New details on how the immune system recognizes influenza

...ions. Dr. Sette and his colleagues have also built numerous tools for analyzing and visualizing the data and for predicting immunity against different pathogens--all of which is publicly accessible on their Web site (see http://immuneepitope.org ). ...

Tracking sperm whales and jumbo squid

...satellite. Jumbo squid also were abundant, with numerous small fishing boats hauling in a total catch of about 10,000 squid per night throughout the six-day study. Captured squid were outfitted with a pop-up archival transmitting tag, which periodically sampled the animal’s depth. Unlike the instruments us...

Type of stem cell found to reside in transplanted lungs

...widely seen as a potential source of therapies for numerous diseases and conditions, such as heart disease, cystic fibrosis, graft-versus-host disease, muscular dystrophy, and as a possible source for improved recovery of cancer patients undergoing chemotherapy. Lama’s laboratory currently is working on a...

Genes set scene for metastasis

...ing cause of mortality in cancer patients ?entails numerous biological functions that collectively enable cancerous cells from a primary site to disseminate and overtake distant organs. A number of genes are already known to contribute to the spread of breast cancer cells to the lungs. Using genetic and p...

Synthetic peptide targets latent papilloma virus infections

... progress to cancer. Earlier work by Botchan and numerous other researchers on the human and cow (bovine) papilloma virus has shown how the virus moves into new cells. It carries its genes in the form of a circular DNA plasmid that nestles in the nucleus of the cell and makes use of the cellular machinery t...

New sucker-footed bat discovered in Madagascar

...s endemic to Madagascar but has been introduced to numerous tropical countries. Myzopoda are found in association with such plants because they can use their suckers to climb and adhere to the leaves' flat, slick surface. They are presumed to roost in the leaves during the day. Myzopoda were considered end...

Bioluminescence at the service of a novel cerebral imaging technique

...sing this approach. This novel technique opens numerous perspectives. This tracer can thus be expressed in all cells of the brain nervous system (both neurons and glial cells) in order to monitor the activity of the whole brain. Preliminary data are already available. For the first time, it is possible...

Researchers from the UGR use a bacterium to obtain biopreservatives from food

FSU researchers determine a critical factor in workings of proteins

...traction increases the rate. "This theory opens numerous opportunities for further study," Zhou said. "For example, we now can begin to uncover the molecular bases of large variations in association rate among proteins. It also might be possible to design proteins with the desired association rate." Att...

Bats prey on nocturnally migrating songbirds

Erectile dysfunction in diabetes is due to selective defect in the brain

...eripheral nervous systems. The site is involved in numerous functions, including erectile function and sexual behavior, and is a primary site within the forebrain that has been implicated in penile erection. The investigators also examined central nitric oxide (NO within the PVN) which plays an important role...

Out of Africa -- Bacteria, as well

.... Like humans, the bacteria are also split up into numerous regional populations. A team of scientists led by Mark Achtman at the Max Planck Institute for Infection Biology, François Balloux at the University of Cambridge and Sebastian Suerbaum at Hanover Medical University have found signs of the parallel e...

Long-lived deep-sea fishes imperiled by technology, overfishing

...sh species, it isn't unusual to find a school with numerous 18-year-old fish, for example, but very few fish that are 17 or 19 years of age. Scientists can determine the age of fish through their otoliths, or ear bones, which regularly accumulate rings much like trees. Variations in the size of the rings can ...

Twenty of world's 162 grouper species threatened with extinction

...ent (GMSA) by IUCN, Conservation International and numerous other partners that provides scientists with baseline data for analyzing threats to ocean species. “This assessment forms part of a growing focus on over-fishing and conservation concerns for fishes in general,?said GMSA Director Kent Carpenter. ...

Bacteria research offers hope for new vaccine against meningococci

...us vaccine candidates and new drugs, obviating the numerous costly and time-consuming tests that have been necessary until now. At the same time, the system provides a clear picture of the process of infection. “With these findings as tools, we can continue to study the course of the disease and test vacc...

Volcanic eruptions, ancient global warming linked

...of the world’s oceans and led to the extinction of numerous deep-sea species. Warming periods in Earth’s history are of interest as analogs to today’s climate change, Duncan said. The international science team was able to link the PETM with the breakup of Greenland from northern Europe through analyzin...

New science of metagenomics 'will transform modern microbiology'
