Research identifies protein that signals flowering in squash plants

...lowering-inducing substance, known as florigen, is produced in the leaves of a plant under inducing conditions, and then is transported through the phloem to the floral meristems, where it acts together with other factors to induce flowering. The precise nature of the florigenic signal has eluded plant biolog...

Research team identifies new Alzheimer's gene

...rom Alzheimer’s patients and that the GAB2 protein produced by this gene is present in those brain cells conta...etrix 500K Arrays, the study’s researchers rapidly produced a genetic map of each brain tissue sample and isolated the GAB2 gene relatively quickly. “This A...

Dual-imaging technique useful before -- and during -- brain surgery

...Leach says the detailed, easy-to-understand images produced from functional MRI data also help patients understand what is happening in their head and how the surgery will be conducted. “We can essentially show patients a color-coded picture of their brain and explain to them where their tumor is in relati...

Researchers examine carbon capture and storage to combat global warming

...on sequestration, traps carbon dioxide after it is produced and injects it underground. The gas never enters the atmosphere. The practice could transform heavy carbon spewers, such as coal power plants, into relatively clean machines with regard to global warming. ''The notion is that the sooner we wean ou...

Newly discovered antibody may be body's natural defense against Alzheimer's

...allmark of Alzheimer's disease. While monomers are produced from birth and appear to be relatively benign, oligomers have been implicated as potent toxins responsible for Alzheimer's-linked memory loss and brain cell death. This has led many scientists to speculate that oligomers may be the main culprit in Al...

CT scan reveals ancient long-necked gliding reptile

...ontained the entire skeleton. Post-scan processing produced an amazingly clear, if somewhat flattened, image of a small reptile with a long neck and swept back wings. Gliding behavior evolved several times in reptiles and is present in the Indonesian reptile Draco. ...

Could fungal collection hold the key to new life-saving drugs?

...er of prescription drugs deriving from metabolites produced by fungi that have been on the market for many years. These include immunosuppressive agents, antibiotics such as penicillin, lipid lowering agents and anti-fungal drugs....

In nature, proteins sweep up nanoparticles

... “We found that the mineral aggregates, which are produced as a consequence of microbial activity, actually contain a lot of protein,” says Banfield. “This is very interesting because biomineralization has traditionally been thought of as a phenomenon that occurs within a cell, or in contact with it. But in ...

Potent possibilities for parasite attack

...eishmaniasis, respectively, with the sequence they produced in 2005 for L. major, which causes a less severe, cutaneous form of the disease. Despite the major differences in disease type, only 200 out of more than 8000 genes present in each genome were found to be differentially distributed between the three ...

Reconstructing the biology of extinct species: A new approach

...ld be irrevocably linked to the type of locomotion produced by its limbs. "If an animal evolves a new way of moving about the world, its organ of balance must evolve accordingly," Walker explains. From the visual information, the animal tracks its position relative to stationary objects such as tree trunks,...

Human genetic 'deserts' are teeming with significant life

...scriptomes [the set of all messenger RNA molecules produced in a population of cells] are made of a swarming mass of different overlapping transcripts, together with our findings that suggest we have only uncovered a portion of its complexity, has important implications for medicine, says Professor Reymond. ...

Researchers identify protein pathway involved in Parkinson disease development

...s is the damage caused to cells by reactive oxygen produced during oxygen metabolism. Although cells have mechanisms in place to protect against oxidative damage, this system can break down in the face of environmental challenges or genetic mutations. The Emory researchers found that the mitochondria...

Children of smokers have more than 5 times higher levels of a nicotine toxin

...r doubled the amount of cotinine, one of chemicals produced when the body breaks down nicotine from inhaled smoke to get rid of it. Sleeping with parents and lower temperature rooms were also associated with increased amounts of cotinine. Cotinine was measured in 100 urine samples taken from infants ...

3-D ultrasound scanner provides in-depth view of the brain

...geons now rely primarily on two-dimensional images produced by MRI or ultrasound, said Edward Light, a research and development engineer in the biomedical engineering department at Duke. "The problem is that without 3-D, you could miss something," he said. MRI machines are also expensive and require a dedicat...

"The trackway at La Virgen del Campo opens the door to several new areas of research," said Costeur. "New biomechanical modeling will increa...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

... creatures that live in the soil. The ‘chitinases’ produced by these genes can degrade the casing of insects and small crustaceans. It is not only animals that can feel the wrath of C. botulinum, explains Dr Sebaihia: "The soil can be a harsh environment and food can be scarce. To see off the competition,...

'Nurse cells' make life and death decisions for infection-fighting cells

...sceptibility to infection. The function of T cells produced by the thymus is to recognize harmful invaders. Once invaders have been identified, T cells then attempt to eliminate disease-infected cells. "In early studies, it was suggested that thymic nurse cells only removed non-functional thymocytes," said...
