Ancient olfaction protein is shared by many bugs, offering new pest control target

In the battle against insect pests, new research indicates that it may all come down to the sense of smell. A group of Rockefeller University scientists who had previously identified a key gene essential for the sense of smell in fruit flies now shows that this ge...

Studies reveal methods viruses use to sidestep immune system

... we're most excited about," said Dr. Gale. "It's a battle between viruses and humans. Viruses have co-evolved with their hosts, so every time we have evolved a gene with a new function that allows us to fight off a virus, the virus adapts and comes up with a new function of its own to counteract our defense...

Computational Method Speeds Mapping of Cell Signaling Networks

...als" that attract other immune system molecules to battle the infection. Components in the pathway are chemically altered during the signaling. Such alterations occur only at points of active signaling in the network. The researchers measured the modified signaling molecules to determine where along the pa...

Leprosy microbes lead scientists to immune discovery

...t only in the milder form, indicating a successful battle against the leprosy bacterium. They were missing, however, in the more severe leprosy infections, meaning that the monocytes hadn't succeeded in producing those key anti-bacterial fighters. "The logic here is that because their monocytes are unable ...

... types of immune cells, or leukocytes to potential battle stations in the body. In certain situations, this ...g mechanisms that mobilize leukocytes to potential battle stations during stress could help us figure out ways to boost the immune response when it could be m...

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...ying on an invasive procedure." Immune cells that battle HIV must constantly divide in order to continue performing their protective functions. The massive amount of division prematurely shortens these cells' ends, or telomeres, ultimately exhausting the immune system. UCLA's previous research shows that ...

Molecular messengers perform a crucial role in the ability of injured nerve cells to heal themselves

...ory of the Greeks over the Persians in the fateful battle of Marathon. A team of researchers at the Weizmann Institute of Science has now discovered how molecular messengers perform a crucial role in the ability of injured nerve cells to heal themselves. A nerve cell has a cell body and a long extension, c...

At the molecular level, the predator is the prey

...ng of an illusion. At the molecular level, another battle rages. And in this second, miniature realm, it's the newt who's the aggressor. Biologists at Indiana University Bloomington, Utah State University and the University of Utah present evidence in this week's Nature that a toxin produced by the rough s...

Chemists synthesize molecule that helps body battle cancers, malaria

...medicinally important molecule that helps the body battle disease, has been achieved by chemists at the University of Illinois at Urbana-Champaign. In clinical trials, QS-21A has been shown to significantly improve the body's immune response in vaccine therapies against aggressive diseases such as melanoma...

Can our genes tell the story of our divergence?

...essures. It could be, for example, that there is a battle between the interests of sperm cells (favoring genetic changes that increase cell number and decrease cell death), and the need for the organism to avoid cancer. Future studies will have to determine whether these explanations - of an evolutionary a...

A new molecule discovered in the battle between plants and disease

...ave discovered a molecule that plays a role in the battle plants must win against bacteria and fungi that would eat them for lunch. The group led by Professor Clarence A. "Bud" Ryan isolated a small protein called Pep1 that appears to act like a hormone, signaling to the rest of the plant to raise its defen...

Seaweed could make junk food healthier

... it will be a valuable weapon in the international battle against obesity, diabetes and heart disease and diseases such as bowel cancer. The research paper examines the properties of a brown-coloured seaweed called Lessonia and Laminaria, found in the Far East, South America and parts of Norway and Scotlan...

AACR Favors 'full spectrum of stem cell research biology'

... community of scientists on the front lines of the battle against cancer, we are firm in our belief that continued experimentation with human stem cells is necessary to improve evaluation of anti-cancer drugs, to identify markers for early detection of cancer, and to illuminate the path to novel, targeted t...

Gradient guides nerve growth down spinal cord

...o these nerves," Zou suggests. "Although half the battle is acquiring the right cells to repair the nervous system," he said, "the other half is guiding them to their targets where they can make the right connections." "Understanding how the brain and the spinal cord are connected during embryonic develop...

Vaccine targets tumors where they live

Vaccine strategies are being designed to battle cancer, but their use for metastatic melanoma is a challenge. Effective vaccines against established tumors require tumor-reactive T cells to traffic to the sites of the tumors and are locally activated there in order to kill cancer cells. A problem ...

Techniques available to detect soil that inhibits destructive soybean pest

...discusses how to use nematode-suppressive soils to battle the root-dwelling pests and the limitations of the techniques. In previous research on a different cyst nematode, Westphal and his colleagues determined that mixing 1 percent to 10 percent of nematode-suppressive soil into the top layer of a soybean...

Kenya halts first field trials of GM maize

...field trials would continue. "This is just like a battle we lost," said Mugo. "But the main war will continue until we help African maize farmers overcome the pest". Stem borers destroy up to 12 per cent of maize growing in Kenya, amounting to US$76 million in lost harvests per year. The IRMA project, wh...
