Storing carbon to combat global warming may cause other environmental problems, study suggests

... To predict whether this increased moisture might boost rainfall to counter tree water withdrawals, co-authors Bruce McCarl of Texas A&M University and Brian Murray of RTI International inResearch Triangle Park, N.C. first investigated where in the United States additional tree plantations would most ...

Membrane research opens window to benefits for plants, humans

...ssage eventually could help agricultural producers boost survivability of drought-stricken and flood-ridden crops. It also could lead to new pharmaceuticals that specifically target these proteins. "The kidneys are responsible for maintaining a water balance in the body," said Swedish co-author Per Kjellb...

UCR environmental scientists propose chemical solution to cleaning California's Salton Sea

... hand could greatly stimulate eco-tourism here and boost the economy of this region." L. B. Mason, C. C. Goodson, M. R. Matsumoto and M. A. Anderson of UCR assisted with the study, which was conducted in 2003-2005. The California State Water Resources Control Board and the Salton Sea Authority provided fi...

Scientists directly view immune cells interacting to avert autoimmunity

... "We now have a pattern to look for when we try to boost or prevent immune responses. 'Clusters' of cells in a lymph node such as we have seen may be indicative of certain unbridled T cell responses. The ultimate hope here is that seeing patterns of T cell activation may ultimately allow similar imaging t...

Primates harvest bee nests in Ugandan reserve

...ca to Brazil as part of a scientific experiment to boost honey production in 1956. From Brazil, it invaded the Americas, working its way northward and is now found in southern U.S. states. Dave Roubik has followed the progress of Africanized honeybees in the New World, documenting effects of pollen and ...

Infection 'alarm' yields clues to immune system behavior

...y promising target for new medications designed to boost or suppress the immune system, the researchers said. An overactive immune system, for example, can set off the excessive inflammation associated with rheumatoid arthritis and lupus. In addition, some cancers are more likely to grow where inflammation...

There's something fishy about human brain evolution

...sially, according to Dr. Cunnane our initial brain boost didn't happen by adaptation, but by exaptation, or chance. "Anthropologists and evolutionary biologists usually point to things like the rise of language and tool making to explain the massive expansion of early hominid brains. But this is a Catch-2...

Clues to breast cancer hidden inside stem cells

Stem cells and how to boost them is hot on the research agenda. But stopping them could be critical too, as evidence implicating stem cells in cancer is mounting. In the human breast, up to 20 per cent of all tumours are now suspected to originate in stem cells. Now scientist...

Defective immune system response to smallpox vaccine detailed in new study

...eams that could be applied to the skin in order to boost its ability to contain vaccinia virus infection. Another approach could be to develop agents to neutralize IL-4 and IL-13. Although no such drugs are currently marketed, compounds that can neutralize IL-4 and IL-13 are under study as possible asthma ...

Front-line immune cells mature in four stages, study shows

... veterinary biosciences. "The findings will also boost NK-cell research," says first author Aharon G. Freud, a physician who is a doctoral student in Caligiuri's laboratory. "The next step is to figure out why they develop in lymph tissue and whether patients with cancer have altered NK cell development....

Protein finding could lead to treatment for inflammatory diseases

... Cytokines are chemicals made by immune cells that boost the immune system by stimulating inflammation to fight infectious pathogens. "We found that the NF-kB levels were always lower in MC160-expressing cells," Shisler said. "This was an exciting new finding because no one had previously found a function...

Do plants have the potential to vaccinate against HIV?

...d her colleagues have found a way to significantly boost HIV-1 p24 protein production in plants by producing an entirely new molecule ?a fusion of the HIV-1 p24 protein and part of another protein, human immunoglobulin A (IgA) - a major component of the immune system. The team found that the HIV-1p24 antig...

Aldwinckle, professor in the Department of Plant Pathology at Cornell University, Geneva, New York, who has developed highly efficient techniques for ...

Nobelist discovers antidepressant protein in mouse brain

...also examined the effect of treatments designed to boost weak serotonin systems on p11 levels in brain cells by administering to mice two types of antidepressants ?a tricyclic, a monoamine oxidase (MAO) inhibitor ?and electroconvulsive therapy (ECT). "These three different ways of treating depression all ...

HIV vaccine takes different tack to boosting immune response

...said Chen. "Hopefully this therapeutic vaccine can boost the natural immune responses strong enough so you don't have to take these anti-HIV drugs all the time." Chen anticipates testing the HIV vaccine in humans in the next several years. He foresees the SOCS1 silencing strategy enhancing therapeutic and...

...ons to help these individuals hide such stains and boost their self-esteem. However, Kim L. Capehart, DDS, MBA, AGD member and clinician, will explain how a new tooth whitening procedure he used on a patient helped significantly lighten these tough-to-remove stains and saved his patient more than $10,00...

Role of protein in immune response may aid HIV research

...ns might be used to develop medications that could boost the body's impaired day-to-day response to bacteria in HIV/AIDS patients and others with compromised immune responses. The scientists announced discovery of the protein called PGLYRP ? peptidoglycan recognition proteins ? earlier this year. Patient...

Iron critical to ocean productivity, carbon uptake

...iron is introduced into the ocean in an attempt to boost productivity. Those studies found that introducing iron into small portions of the Pacific did indeed trigger phytoplankton growth, but it wasn't as robust or as sustained as models predicted. "It wasn't the silver bullet that scientists originally ...
