A new kind of mutation could explain numerous phenotypic variations in various species

...g). It will assist researchers around the world in discovering similar phenomena for other phenotypes including hereditary diseases. ...

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere

...eate DMS that rises into the air. "Isolating and discovering a novel, keystone bacterium from the ocean first, and then sequencing its genome enabled this team to find the genes involved in the DMSP cycle," said Matthew Kane, program director in the National Science Foundation (NSF) Division of Molecular and C...

UGA scientists engineer root-knot nematode resistance

...rcent of all infestations in agricultural land. By discovering a root-knot nematode parasitism gene that's essential for the nematode to infect crops, the scientists have developed a resistance gene effective against all four species. Using a technique called RNA interference, the researchers have effectively t...

How many genes does it take to learn? Lessons from sea slugs

... gotten an unprecedented look at brain mechanisms, discovering that the neural processes in even a simple sea creature are far from sluggish. At any given time within just a single brain cell of sea slug known as Aplysia, more than 10,000 genes are active, according to scientists writing in Friday's (Dec. 29,...

Molecular 'on/off switch' controls immune defenses against viruses

...leted several breakthrough studies on hepatitis C, discovering that the RIG-I protein binds to viral genetic material. Then, RIG-I changes its shape and sends signals to other proteins that spur production of interferon, a molecule that stops viral replication. The researchers also found that the virus launches ...

Researchers discover key mechanism by which lethal viruses Ebola and Marburg cause disease

...t deadly viruses the world over." The method for discovering this protein underscores the power of bioinformatics for addressing the challenges of emerging infectious diseases. The investigators are currently exploring whether insights derived from understanding the potency of these immunosuppressive peptides...

MIT's molecular sieve advances protein research

...could be used to replace 2D gels in the process of discovering disease biomarkers, as well as to learn more about disease. ...

Mutant mouse provides insights into breast cancer

By discovering a mutant mouse that is highly susceptible to mammary tumors, Cornell researchers have found a novel potential link between genetic defects in DNA replication (copying) and breast cancer. The mouse contains a mutation in a gene essential for replicat...

Novel pathway regulates timing of brain cell development

...ology Program at Children's Hospital Boston report discovering a new molecular pathway that influences the timing of nerve-cell production. The pathway--which acts through a novel and unexpected mechanism--inhibits production of astrocytes during the early stages of brain development, thereby favoring the produ...

Peering into the shadow world of RNA

...Nishikura says, a growing number of scientists are discovering other links between RNA editing and the activities of different forms of non-coding RNA. “We used to believe there were only a limited number of RNA editing sites,?she says, “but now we think there may be as many as 20,000 sites involving perhaps ...

Scientists unravel clue in cortisol production

...l steroid hormones. Researchers were interested in discovering what events have to occur in order for SF-1 to bind to DNA. The first thing they found was that because DNA is so tightly packed in the nucleus, SF-1 can't bind to it until it's unpacked by a group of proteins. Once that happens, SF-1 binds to the...

Antibody signal may redirect inflammation to fuel cancer

... to become fully malignant, UCSF scientists report discovering an apparent trigger to this potentially deadly process. Typically, the "innate" immune system's Pac-Man-like white blood cells, or leukocytes, engulf and destroy invading microbes when receptors on their surface receive a signal from serum in the b...

Small molecule dervived from Rb2/p130 could act as cancer therapeutic

...roval for clinical trials. "Fifteen years after discovering Rb2/p130, our research and hard work has led us to the discovery of this small molecule, which is a step forward in cancer research and a big step toward a cancer treatment," he said. ...

Old dinosaur research leads to new honor

... Engineering Research Council grantee Robert Reisz discovering the oldest known dinosaur embryos and the oldest known reptile that stands on two legs. Now, he is being honoured for more than 35 years of research excellence by joining the ranks of the American Association for the Advancement of Science (AAAS)....

Discovery could lead to better control of hemorrhagic fever viruses

Researchers report discovering the receptor through which a group of life-threatening hemorrhagic fever viruses enter and attack the body's cells, and show that infection can be inhibited by blocking this receptor. The findings, to be published online by the journal Nature on Febr...

From the deep -- Researchers find new species of sea anemone

...f a dead whale. A marine biologist would say that discovering a new sea anemone isn't so unusual. But finding one that calls a dead whale home is what sets this new creature apart. Since the scientists who initially found these animals weren't sea anemone specialists, they sent the 10 specimens they collecte...

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

...our partnership will prove the winning formula for discovering new pharmaceutical drugs to fight cancers, diseases and resistant strains of infections such as MRSA.” SIDR brings together scientists from different disciplines to focus on drug discovery. They have developed test systems to detect biological act...

Genetic factors are linked to fever following smallpox vaccination

...ake vaccines even more acceptable in the future by discovering ways to further reduce the chance of minor adverse events.” In an accompanying editorial, James E. Crowe Jr., MD, of Vanderbilt University Medical Center, echoes Dr. Stanley’s sentiments that the findings represent an important preliminary step ...
