Stopping plants from getting sick

... have sequenced the genome of a smut fungus, I can look through thousands of genes on my desktop computer." Kronstad is now using his NSERC-funded research as a foundation to fight an outbreak of the yeast fungus Cryptococcus on Vancouver Island, applying his research on plants to help investigate how ...

Cancer researchers add spice to research against rare neuromuscular disease

... away the substances that turn on the receptor, we look for ways to attack the faulty receptor directly. In this experiment, for instance, the mice treated with ASC-J9 have normal fertility and are completely healthy sexually, which wouldn't be the case if we simply took away testosterone." ...

Old dinosaur research leads to new honor

...ntologist at the University of Toronto. "I like to look at the very beginnings of major evolutionary events ?to that time when mammals and reptiles and birds were just becoming separate from each other. It was an exciting time in history, about 270 million years ago ?it was between ice ages, just like the...

Jefferson researchers' discovery may change thinking on how viruses invade the brain

... the story." "We think we have to have a closer look at how viral transport in general works," Dr. Schnell says. "Viral transport has to be revisited." Next, the scientists plan to pay closer attention to other parts of the dynein-LC8 interaction, and attempt to find other proteins that could be inv...

Lead with a poisonous electron shield

...himie Théorique, Université Paris 6) took a closer look at two proteins to which lead likes to bind. Calmodulin, a calcium-binding protein, plays an important role in regulating and transporting the calcium cation in the human body. A calcium ion binds to seven ligands at the active centers of the enzyme....

New bird, bat species revealed by extensive DNA barcode studies

...oping this symposium I am hosting will help people look at cancer in a new light." After growing up on a wheat and cattle ranch in Oregon, von Borstel was drafted into the U.S. Navy as a seaman first-class in 1944. Following the Second World War, he pursued his university education in the United States...

Cancer that colonizes our bodies

Scientists uncover new target in cancer mutation puzzle

...ne mutations in tumors with p53 mutations, we will look for other molecules with similar features," Land said. "Our hope is that this line of research will give us a range of novel opportunities for treatments of cancer patients. We are at the beginning of a new and exciting road." ...

Largest genomic search finds genes that may contribute to autism

...archers used so-called "gene chip" technologies to look for genetic similarities among these family members. In addition, the team scanned the same DNA for what are called copy number variations. These are submicroscopic insertions and deletions of genetic material that scientists believe may be involve...

Mosquito genes explain response to climate change

...t does tell us in what parts of the genome we must look to identify the mechanism of photoperiodism," Bradshaw said. Collaborative studies already are underway to determine the same genes in stickleback fish at the UO and in fruit flies at the University of Pennsylvania. "The response to climate warmin...

How to manage forests in hurricane impact zones

...d resources. The recovery period is a good time to look at how to reduce the vulnerability of forests." Vulnerability can be lessened by converting to species that are less susceptible to hurricane damage, by controlling stand structure, and by dispersing harvesting and thinning operations. The author...

Neural bottleneck found that thwarts multi-tasking

...rforming complex tasks. "It may be possible to look to the sort of tasks people are going to have to do in a very complex environment, such as flying a plane, and find out under what circumstances these tasks may be less vulnerable to dual-task interference," Dux added. For the record, neither Maro...

Prehistoric mystery organism verified as giant fungus

... the same type. "But if you’re an animal, you will look like whatever you eat," Boyce said. And Prototaxites displayed a much wider variation in its ratio of carbon-12 to carbon-13 content than would be expected in any plant. Geological processes can alter the isotopic composition of fossils, but Boyce...

Making mice with enhanced color vision

...ight that was twice as bright as a red light would look identical to the red one. But if the animal adds a second photoreceptor with different absorption properties, then by comparing both receptors, the red and green lights could always be distinguished." Normal mice failed to discriminate yellow ve...

Cracking open the black box of autoimmune disease

...n Nature. "With this new list of genes, we can now look for possible therapies with far greater precision." The immune system is often described as a kind of military unit, a defense network that guards the body from invaders. Seen in this way, a group of white blood cells called T cells are the frontl...

2,000 influenza virus genomes now completed and publicly accessible

...enetic factors that determine their virulence, and look for new therapeutic, vaccine and diagnostic targets," says NIAID Director Anthony S. Fauci, M.D. The Influenza Genome Sequencing Project, initiated in 2004, has been carried out at the NIAID-funded Microbial Sequencing Center managed by The Instit...

Organic is healthier: Kiwis prove that green is good

...e effects on the health. “The authors also did not look for any plant secondary metabolites of potential toxicological impact.? According to the Soil Association, organic food sales in the UK increased by 30% to £1.6bn in 2006. The world market for certified organic foods was estimated to be worth US $2...

Short chromosomes put cancer cells in forced rest

...to the cancer’s returning," says Greider. A closer look showed microtumors in the mice’s lymph nodes that had begun the road to cancer, but stopped, falling instead into a state of senescence. "They don’t die, they don’t divide, they just sit there in permanent rest," says Greider. Greider, who won th...

Bacterial response to oxidation studied as toxin barometer

...icrobes in wastewater systems, Nancy Love began to look for other applications, from water monitoring in general to specific health monitoring in other biological systems in the environment, and met Rzigalinski, who is focused on neuroscience, particularly brain injury and aging, and nanotechnology (http:...
