Mechanism for the captation of nutrients in plants- unknown to date

...tion. If this is the case, it will be necessary to discover what are the genetic and molecular mechanisms involved in the process, in order to improve the plant varieties. For example, in order to increase starch production in potato or maize, endocitosis would have to be encouraged through the stimulation of...

Chickadees can help humans get their bearings

How did University of Alberta researchers discover that animals zig when they were only supposed to z...niversity of Alberta researchers were surprised to discover the birds contradicting prior research that showed how animals navigate. This study is the first to ...

Brain Scan Study of Smokers Reveals Signature of Craving

... understand the underlying brain processes, we may discover new methods for manipulating those responses to better help smokers quit." While scientists have thought that nicotine is the primary agent responsible for cigarette addiction, recent evidence suggests that conditioned responses to sensory cues also...

Scientists map the world for nature conservation

...botanists. Greater efforts are needed in future to discover more about the plant life they contain. The project was conducted as a component of the large-scale BIOLOG-BIOTA programme, funded by German's Federal Ministry of Education and Research (BMBF) and run with the cooperation of the World Wildlife Fund (...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...nd in the area. Scientists were also intrigued to discover among other things two species of sand flea-like crustaceans (amphipods) which, though familiar, had never before been found in an ice environment. Animal density far higher than expected "Overall, the densities of animals are much higher than expe...

High fidelity keeps human DNA assembly line humming

... a growing strand of RNA. Burton's insight was to discover that the NTP bases preload to the DNA template several steps before they are added to the growing RNA chain. This idea contradicts the prevalent view of how RNA and NTP bases hook up. Preloading of NTPs hints at a previously unknown quality control ...

Searching the depths of the straits of Florida for disease cures

... illegal drug smuggling, but researchers expect to discover pristine reefs there down to 3,000 feet that could lead to a new reputation for the area as the source of lifesaving drugs. Regular dispatches and photos from the expedition will be posted at http://www.at-sea.org. "We don't really know what organis...

Function of new cancer genes discovered

... Nijman and his colleagues used genetic screens to discover the molecular mechanism underlying cylindromatosis. Nijman's research revealed that the CYLD protein plays an important role in the NF-kappa B signalling route. This is a cellular communications system which becomes overactive if the CYLD protein is ...

Experiment station researchers to explore genome of disease-fighting fungus

...ponsible for producing antibiotics and potentially discover novel antibiotics used in therapy for humans or animals. "We know some of the genes responsible for known antibiotics, however, there are additional genes in Trichoderma responsible for producing uncharacterized compounds that might be novel antibio...

Molecular thermometers on skin cells detect heat and camphor

...biologists and neuroscientists have been trying to discover the basic molecules and mechanisms that underlie t...ered TRPV3 a few years ago, they were intrigued to discover that it is unique among thermoTRP channels in that it is expressed on the surface of skin cells know...

Science study holds implications for gene therapy and stem cell biology

...me insertion of disabled retroviruses as a tool to discover genes that enhance the fitness of stem cells. Such genes are of great interest for regenerative medicine because they can improve the prospects of stem cell-based therapies. Stem cells are very rare in the body and typically need to be multiplied for...

The biggest family tree ever

...s family trees, ones that are almost impossible to discover through traditional genealogical methods. In contrast to written historical records that can be lost or oral histories that can fall into disuse, the information stored in people's genes persists. Cusanovich had his own DNA analyzed, which helped hi...

Disease progression model of pancreatic cancer developed by Penn researchers

...s for treatment. The researchers were surprised to discover a high degree of heterogeneity in expression among these key molecules across the specimens. After ruling out the likelihood that this variability resulted from additional acquired mutations in known key tumor suppressor pathways, Hingorani suggests,...

Supercomputers to focus brains on AIDS dilemma

...story of molecular dynamics simulations in helping discover HIV-1 protease inhibitors may be repeated with HIV-1 integrase inhibitors," said McCammon. "This could potentially save many lives in the fight against HIV/AIDS." The molecular dynamics simulations, carried out at SDSC and other sites, and the devel...

MUHC scientists describe genetic resistance to rampant virus

...s for fighting viruses; in the future we expect to discover additional resistant genotypes." CMV infects most of the world's organisms, including upwards of 80% of the human population. Although healthy people suffer only mild symptoms, infection can trigger fatal reactions in those with a compromised immune...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...er animals 'see' the world as we do. Every time we discover otherwise, it expands the horizons of scientific knowledge and sends us the humbling and vital message that we are not, after all, 'the measure of all things.'" Planthoppers and pachyderms Larom met O'Connell-Rodwell in Etosha in 1992, the year she...

Sickle cell and protection against malaria

...ere is an immune component to this protection. To discover whether the protection provided by HbAS is innate or varies with age, the authors studied age-specific malaria in a sample of children and adults in the Kilifi District of coastal Kenya. Protection against mild malaria increased up to 60% at age 10, ...

Stem cells from brain transformed to produce insulin at Stanford

...al stem cells is completely new. "The more ways we discover to form insulin-producing cells from stem cells, the more likely it is that stem cells can be used for islet replacement," Kim said. Kim hopes this work, or related work with other sources of stem cells, could one day replace human islet cells in pe...

How the environment could be damaging men's reproductive health

... Prof Giwercman. The study did not enable them to discover whether the increase in Y chromosome sperm would lead to an increase in boys being born, or what might be the mechanism involved. "We need a much larger population in order to investigate the implications of these changes on sex ratio of offspring as...

Effective Cancer Treatments Follow The Clock

...nction. We are also planning additional studies to discover the molecular signals from the circadian machinery to the immune system that might prove to be useful drug targets.?/p>...
