Government development policies, not communities, main threat to forest conservation projects

...huayo reserve grew from strong community action to defend fish stocks and prevent access to extensive forest uplands by outsiders. It has worked in the sense that the variety of plant and animal life has not diminished, and management at local level has been highly flexible and able to adjust to changing ne...

Gene found to defend against environmental pollutants and pulmonary emphysema

...he degree of lung damage depends on the ability to defend against environmental factors. We now know that Nrf2 is the key player in protection even in the case of chronic exposure to pollutants." In 2002, Dr. Biswal and colleagues were the first to show that activation of Nrf2 in response to an anticancer a...

UCLA scientists uncork fountain of youth for HIV-fighting cells

...helping the AIDS patient's exhausted immune system defend itself against HIV. The researchers extracted immune cells from the blood of HIV-infected persons and tested what would happen if telomerase remained permanently switched on in the cell. "By exploiting telomerase's growth influence on telomeres, we...

Researchers discover defense mechanisms in some plants believed bred out by humans

...tivated to serve humans' needs lost the ability to defend themselves. So costly pesticides that are sometimes harmful to the environment now defend the plants from the same things they used to be able to fight on their own. Asim Esen, biology prof...

New pheromone creates buzz about the clout of older bees

... ones that go out to collect nectar and pollen and defend the hive, and those that stay home and nurture the larvae. Huang had documented that this balance is controlled by the elder bees, those that typically spend the final one to three weeks of their five-week lifespan out in the field. Experiments show...

K-State professors develop vaccine to prevent abscess in liver of cattle

...s white blood cells or leukocytes, which generally defend the body from germs or infections. The vaccine prevents abscesses from occurring by neutralizing the toxin, which is a protein. Once injected into the animal, antibodies are produced that act on the protein. When the bacteria goes into the liver and ...

Plant protein mimics hormone that mitigates diabetes and obesity

...elongs to a large, diverse family of proteins that defend plants from fungal pathogens. Bressan and his colleagues report in the current issue (Friday, Jan. 21) of Molecular Cell that a protein in mammal muscle cells called a receptor, which normally binds to the hormone adiponectin, also binds osmotin. The...

Plants, animals share molecular growth mechanisms

... how cells respond to external stimuli so they can defend themselves against insect or fungal attacks," Szymanski said. A protein complex known as Actin Related Protein 2/3 (ARP2/3) is a cellular machine that controls formation of actin filaments, which are important for cell growth and movement. Actin fila...

Defenseless plants arm themselves with metals

...YETTE, Ind. - A group of plants that uses metal to defend against infection may do so because the normal defense mechanism used by most other plants is blocked. Purdue University researchers found that this group of plants produces, but does not respond to, the molecule that triggers the infection response ...

Antioxidant blood levels key to MnSOD gene

...yme that works as an antioxidant in human cells to defend against disease. The MnSOD gene is passed from parents to offspring in one of three forms: VV, VA or AA. "Compared with men with the MnSOD VV or VA genotype, people with the AA genotype seemto be more sensitive to the antioxidant status," said Li. ...

How important is sexual conflict?

...te females, while females again evolve measures to defend against manipulation, potentially setting off an endless evolutionary cycle of adaptation and counter adaptation. As with many exciting areas of biology, however, controversy exists over the details and generality of the scenario outlined. Sexual con...

Genetic testing could bolster radiotherapy's effectiveness against cancer

...ting. "We have discovered that breast cancer cells defend themselves on the molecular level against radiation, and this response could be reducing the effectiveness of modern medicine's fight against cancer," said Li, who is an associate professor of health sciences in Purdue's School of Health Sciences. "B...

NJIT professor explains bird songs with science, poetry, music

... Rothenberg. "Songs are used to attract mates and defend territories, but the form is much more than function. Nature is full of beauty, and of music." David Rothenberg is the author of Sudden Music: Improvisation, Art, Nature (University of Georgia Press, 2001) Blue Cliff Record: Zen Echoes (...

Scientists discover how plants disarm the toxic effects of excessive sunlight

...t used to sense the presence of singlet oxygen and defend itself from this toxic substance. He notes that the response mechanism is likely highly conserved across species from microbes to plants and humans - and therefore very applicable to other fields of study. For example, too much sunlight can actually...

Study: Plants use dual defense system to fight pathogens

...etween two biochemical pathways that plants use to defend themselves against pathogens pathways that scientists have long believed worked independently of each other. Knowing how these pathways of immunity work may one day help researchers breed plants that can better resist a variety of pathogens, said D...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...oth in biology. "Plants use resistance proteins to defend themselves against pathogen attack by initiating a defense response," Holt said. "The proteins RAR1, HSP90 and SGT1 were previously thought to work together to help resistance proteins in this function. To our surprise, we found that SGT1 can actuall...

Gene changes linked to deficient immune suppression in MS

...re white blood cells produced by the human body to defend against infection. Scientists believe a sub-group of "pathogenic" T-cells cause MS by attacking myelin, the fatty sheath insulating nerve fibers in the brain and spinal cord. As a result, the fibers can't conduct impulses, leading to such chronic neu...

Purdue researchers find key to rice blast fungus

...the rice leaf cells, the infected cells attempt to defend the plant by dying. This means death for young plants, while in older plants, rice grain is lost. The biggest rice blast problem is in Asia and Latin America where rice is an important food staple. About two-thirds of the people in the world rely on ...
