New tooth enamel dating technique could help identify disaster victims

...ive off plants, the carbon-14 concentration in our bodies closely parallels that in the atmosphere at any one time," he said. Buchholz and his colleagues analyzed 33 teeth from 22 different people whose ages were known. The enamel separations were done at the Karolinska Institute, and sample preparation an...

Drugs from the deep blue

...at could be made from natural products in the soft bodies of some of the ocean's simplest inhabitants. "Three quarters of the world is covered by oceans, and we've only dipped below the surface," Molinski said. This chemist sees natural products from marine organisms as an opportunity to answer questions ...

Scientists use gene transfer technology and common virus to block neuropathic pain

... through the axon back to the sensory ganglia cell bodies next to the spinal cord," says Shuanglin Hao, M.D., Ph.D., a U-M research investigator and first author of the study. "Since the vector lacks essential viral genes for replication, it remains in the nucleus expressing the GAD enzyme, which triggers ...

Hurricane aftermath: Infectious disease threats from common, not exotic, diseases

... in the city poses a risk of infection. "Decaying bodies pose very little risk for major disease outbreaks," says Berkelman. Furthermore, mosquitoes do not spread disease by feeding on dead bodies. There is, however, a risk of mosquito-borne diseases such as West Nile because mosquitoes breed in standing w...

New study finds how cells with damaged DNA alert the immune system

...ent a special challenge because they are still the bodies own cells, albeit ones in which the genes have gone awry. "Many scientists question the importance of the immune system in stemming the development of cancer," said David H. Raulet, professor of immunology at UC Berkeley's Department of Molecular an...

Oceans turning to acid from rise in CO2

...to Earth's climate. International and governmental bodies must focus on this area before it's too late." The pH (potential of Hydrogen) scale is from 1 to 14, with 7 being neutral. Anything that lowers pH makes the solution more acidic. The scientists calculated that over the past 200 years, the pH of the ...

Researcher says flu responders can learn from 1918 epidemic

CO2 sensing proves critical for fungal pathogens to adapt to life in air and human hosts

...hesis of a polysaccharide capsule is key. In the bodies of mammals, the CO2 concentration is more than 150-fold higher (5%) than it is in atmospheric air (0.033%). Consequently, C. albicans and C. neoformans are exposed to dramatically elevated CO2 concentrations when causing systemic disease. In their re...

New insights into the software of life

...ide the code for making the building blocks of our bodies - the proteins ?and the consortium has a made a massive step towards identifying all of those building blocks. But the genome must also contain the code to ensure that protein building blocks are made in the right place at the right time. "The new ...

Missing fossil link 'Dallasaurus' found

...e quick to deteriorate under ocean currents; their bodies often fell victim to the ravages of other sea life, such as sharks, who would pick away at carcasses for food. Because of their mostly shallow sea and seaside habitats, the remains of early mosasaurs are even more rare and much harder to find. But i...

Free-energy theory borne out in large-scale protein folding

...es of biology. At any given time, each cell in our bodies contains 10,000 or more of them. Each of these proteins is a chain of amino acids strung end-to-end like beads in necklace. For longer proteins, the chain can contain hundreds of amino acids. Thanks to modern genomics, scientists can use DNA to deci...

Sleeping sickness parasite shows how cells divide their insides

...oteins to different membranes in the cell. "Basal bodies in particular and centrosomes in general have been implicated in the biogenesis of a number of membrane-bound organelles," said Warren. "It prompted us to study further their role in Golgi duplication." Warren's group has identified a new cellular ...

Ancient DNA helps UF researchers unearth potential hemophilia therapy

...life-threatening for people with hemophilia, whose bodies don't produce enough of a protein that prevents prolonged bleeding. Now University of Florida researchers may be one step closer to finding a safe way to spur production of this missing protein in patients with the most common form of the hereditary...

Tissue engineers try to capitalize on the body's own regenerative powers to grow replacement tissues that can be transplanted without risk of rejection. Donor cells from the p...

Tiny polyps gorge themselves to survive coral bleaching

... organisms that host one-celled algae within their bodies for mutual benefit. The coral polyp, a relative of jellyfish and anemones, provides a safe home within its cells for the algae while the algae convert sunlight into energy for the polyp. Grottoli said that when the temperature of the waters around ...
