Important gene controlling tree growth and development found

...milar to the Arabidopsis FT gene, the gene that is producing the messenger molecule that controls the flowering of annual plants and that is considered to be the so called ³Florigen². Results concerning the Arabidopsis gene were published last year by the Nilsson group, also in Science. This finding was ranked...

Just like us, social stress prompts hamsters to overeat, gain weight

...matic stress they often head for the refrigerator, producing unhealthy extra pounds. When Syrian hamsters, which are normally solitary, are placed in a group-living situation, they also gain weight. So scientists at the Center for Behavioral Neuroscience at Georgia State University are using hamsters as a mod...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

...er, the new technology opens up the possibility of producing chickens with enhanced agronomic traits, including...ggs. The use of primordial germ cells, the ease of producing small or large flocks of chickens, and the existing infrastructure for rearing chickens and processi...

Large-scale genomics project will hunt genes behind common childhood diseases

... Dr. Hakonarson. "The equipment will be capable of producing approximately 150 million genotypes per day, all extracted from blood samples. Children's Hospital will be the only pediatric hospital to have this technology entirely at its disposal." The Center plans to analyze blood samples from over 100,000 chi...

Bone marrow may restore cells lost in vision diseases

...eristics. Furthermore, these cells were capable of producing pigment - a colorful indication that the RPE could only have arisen from the donor bone marrow stem cells. "We did not use a direct model of age-related macular degeneration," Scott said. "But we now know that when RPE is injured, it can be replaced...

Drug dials down the energy within cells, UM researchers find

...e specific enzyme, F1F0-ATPase, is responsible for producing most of the cell's ATP. That's a critical role because ATP, often referred to as the cell's energy currency, is the molecule that captures chemical energy from food and transfers it to energy-demanding processes, such as muscle contraction and the tr...

Corals switch skeleton material as seawater changes

... magnesium-to-calcium ratio less than 2-to-1 began producing a large portion of their skeleton with the calcite mineral, while those grown in unmodified modern seawater produced exclusively the aragonite mineral. Though most scientists believed that corals were programmed to produce only the aragonitic form o...

Proteins as parents

... British Columbia (Vancouver, Canada) succeeded in producing proteins with new mechanical properties through the combination of two "parent" protein fragments. The research group of Hongbin Li chose two different titin domains from heart muscle for their experiments. Titin, a giant molecule, is responsible f...

Researchers attack tumor cells by exploiting dependency on sugar metabolism

...itch to what is known as a "glycolytic phenotype," producing ATP through a process that can occur in the absence of oxygen and involves conversion of glucose to lactate. Scientists believe that the glycolytic phenotype enables rapidly proliferating tumor cells to survive even when environmental oxygen levels a...

Biofuels researcher searches for new sources

...borators are investigating Montana's potential for producing biofuels using "biomass," which refers to all biologically produced materials like grains, straw, hay, trees and fruits. He and his collaborators are working on a project to evaluate the ethanol production potential of various straws, hays, and silag...

Infected for life

...sis is prevented. Because the latent virus is not producing any viral proteins the immune system of the infected individual cannot detect the infected cell. Latent HSV-1 infections form in neuronal cells of the peripheral nervous system. When a latent infection is reactivated (by stress of many kinds), HS...

Loosen up, DNA: Leukemia gene changes genetic packaging

...e was inserted ?the gene was silent when expected, producing flies with white eyes, and active when expected, producing flies with red eyes. But in flies with increased JAK/STAT signaling, similar to what occurs in many ...

Scientists take 'snapshots' of enzyme action

...e trimethylamine through breath, sweat, and urine, producing a fish-like odor that can be embarrassing and result in psychological effects such as withdrawal and depression. People with defective FMOs might also suffer additional side effects from drugs, industrial compounds, or other chemicals. ...

Harmful Algal Blooms monitored from space in Chile

... Algal Blooms, which occur when some algae species producing poisons bloom rapidly in water, causing physical or biochemical damage to fish and shellfish. Early detection of Harmful Algal Blooms (HABs) allows fish farmers to make timely key decisions in order to minimise the damage to aquaculture. To aid in ...

Brain-computer link lets paralyzed patients convert thoughts into actions

...he trial and continued to aid the clinical team in producing valuable feedback concerning the BrainGate technology. The second patient, a 55-year-old man with a similar injury, had the sensor implanted by surgeons at the University of Chicago in April 2005 and was followed by researchers from the Rehabilitat...

Scientists identify gene involved in stem cell self-renewal in planaria

...e the stem cells to differentiate, instead of also producing new stem cells to maintain the population." While there is still much to be learned about stem cell self-renewal, the researchers' results suggest that Bruli protein is required for stem cell maintenance in planarians. "The next steps are to see if...

Invasive species alter habitat to their benefit

... change the ecosystem through litter accumulation, producing an environment in which native plants don't perform well but the invaders do," said Farrer. "As the environment changes, the cattails get more abundant and change the environment even more, resulting in even more cattails. It's interesting---and sobe...

EGF receptor activation prevents microbes from going more than skin deep

...nt an immune response to kill invading microbes by producing antimicrobial polypeptides (AMPs). As overt infection in the skin is a rare event, researchers have theorized that AMPs must not only help fight infection, but play a role in preventing infection from developing in the first place. In a study appear...

Basic work on E. coli identifies two new keys to regulation of bacterial gene expression

...ion in detail allows us to harness these cells for producing products of biotechnological importance, like pharmaceuticals." Gourse's work was supported by the National Institutes of Health, the United States Department of Agriculture, and by Pfizer Biotechnology. His team included graduate student Shanil Hau...

Wild vs. lab rodent comparison supports hygiene hypothesis

...or antigen, its immune system kicks into action by producing antibodies that bind to the invader and destroy it. Of the many classes of immunoglobulins (Ig), the IgG type is often involved in autoimmune disease, while the IgE type is likely a key defender against parasites and has been implicated in allergic ...
