Researchers develop new method to help find deadly malaria parasite's Achilles heel

...lead to the development of antimalarial drugs that exploit that difference. Researchers at UCSD have discover...lead to the development of antimalarial drugs that exploit that difference. The scientists will report in the Nov. 3 issue of Nature a comparison of newly dis...

Bees solve complex colour puzzles

...mation. 'One long-term aim of our research is to exploit this understanding to build seeing robots that, like the bee with its mere one million neurons, can learn to find a simple flower in a meadow, which no machine can do at present. Our lab has reconstructed our specially designed bee flight arena - kno...

Scientists discover interplay between genes and viruses in tiny ocean plankton

... evolution and helping scientists see how microbes exploit changing conditions, such as altered light, temperature and nutrients. "These results tell us that even the smallest organisms show genetic variation related to the environment in which they exist," said Philip Taylor, director of the National Scien...

MIT: Oceans are a major gene swap-meet for plankton

...tists see how photosynthesizing microbes manage to exploit changing conditions such as altered light, temperature and nutrients. The work will be reported in two articles in the March 24 issue of Science. As a result of the new findings, "we are beginning to get a picture of gene diversity and gene flow i...

Genome sequencing is for ecologists, too

...gy, but rarely in ecology. Scientists are eager to exploit genomic technologies and genomic experimental approaches that have already revolutionized research in the human health sciences, with the goal of diagnosing the state of aquatic environments. Despite their common name, water fleas are not insects bu...

Research could lead to better drugs and whiter whites

... the longer term, this research could also help us exploit enzymes more successfully and lead to better manufacturing processes in a number of commercial sectors. "In cleaning products, for instance, enzymes help speed up the chemical reactions that break down protein and starch stains; a better understandi...

For the first time: Longevity modulated without disrupting life-sustaining function

...periments, meddling with this versatile pathway to exploit its beneficial effects on aging and life span inevitably invited a host of problems," says Andrew Dillin, Ph.D., an assistant professor in the Molecular and Cell Biology Laboratory at the Salk Institute for Biological Studies and leader of the study,...

Molecular force field helps cancer cells defend against attack

... discovery provides an important clue as to how to exploit this overexpression for the therapy of human cancers." Steven Frisch, a professor of biochemistry and molecular pharmacology at West Virginia University, said the research raises "the compelling possibility of targeting FAK for a novel cancer therap...

Study fishes out new role for prostaglandins

...t can spell the end for an embryo, finding ways to exploit this pathway could have beneficial effects in cancer cells. "The pathways important for regulating development are also dysregulated in cancer," said DuBois, who studies prostaglandin signaling in colon cancer. Knowing how prostaglandins regulate c...

MIT researchers build tiny batteries with viruses

...esearch, Belcher and colleagues learned they could exploit the abilities of microbes to recognize the correct molecules and assemble them where they belong. A new means of inducing this order comes from self-assembly, a tool that is commonly used now in Hammond's lab. "By harnessing the electrostatic natur...

When the going gets tough, slime molds start synthesizing

Scientists tie several cancers to common 'oncogene engine'

...owth.In the short term, clinicians will attempt to exploit this interconnectedness by using therapies that may be effective against one tumor to try to treat other tumors, said Fisher. "In the longer term, the focus is on targeting the real culprit ?and that is the MiT transcription factors or their targets....

Drug dials down the energy within cells, UM researchers find

...on disease-causing cells. In an attempt to better exploit its therapeutic properties, the researchers have been studying the details of Bz-423's activity. They learned that the compound targets an enzyme inside mitochondria, the energy factories of cells. The specific enzyme, F1F0-ATPase, is responsible for...

New angiogenesis finding may help fight cancer growth

Cell wall of pneumonia bacteria can cause brain and heart damage

...h onto PAFr. "S. pneumoniae have learned how to exploit PAFr and use it as a ferry to cross the endothelium of the blood vessels and escape from the bloodstream," Tuomanen said. "From there they enter the cardiomyocytes or neurons in the brain by binding to PAFr on those cells as well." The investigato...

'Erectile dysfunction' drugs heighten natural anti-cancer activity

... Borrello and his colleagues found that tumors exploit nitric oxide-producing immune cells to create a sort of "fog" that keeps them hidden from white blood cells (T-cells) that mount attacks on tumors. These NO-producing cells, a.k.a. myeloid-derived suppressor cells (MDSCs), normally use nitric oxid...

A valuable fly for research into disease

... therapies. Moreover, more and more companies that exploit this model system are being established worldwide. In order to highlight the potential of applied science, the organizers of this conference have invited two of the main pharmaceutical companies currently making considerable investments into research...

Novel laboratory technique nudges genes into activity

...rolled, as well as how scientists might be able to exploit the process to develop new drug targets, Dr. Corey said. For example, current methods to block gene expression, such as RNA interference, rely on using RNA strands to intercept and bind with messenger RNA. While RNA interference is an effective to...

Virtual duck bills demonstrate species coexistence

...hological or physiological traits that allow it to exploit some resources more efficiently than all other species. Such partitioning of resources essentially provides each species with exclusive access to resources necessary for its survival. Although coexistence is often attributed to interspecific differen...

Whitefly spreads emerging plant viruses

... adaptive capacity of B. tabaci and its ability to exploit agricultural systems," Brown said. B. tabaci has proven difficult to control partly because of its tendency to develop insecticide resistance. "As the population levels of the whitefly B. tabaci continue to remain robust, new species of plant vir...
