Nitrous oxide emissions respond differently to no-till depending on the soil type

MADISON, WI, October 20, 2008--The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but also influence nitrogen dynamics. Soils under no-till usually host...

Amphibians respond behaviorally to impact of clear cutting

COLUMBIA, Mo. The number of amphibians drastically decreases in forest areas that are clearcut, according to previous studies. A University of Missouri researcher, however, has found that some animals may not be dying. Instead, the Mizzou biologist said some animals may be moving away (possibly t...

Plants can be used to study how and why people respond differently to drugs

RIVERSIDE, Calif. While prescription medications work successfully to cure an ailment in some people, in others the same dose of the same drug can cause an adverse reaction or no response at all. According to a research team led by Sean Cutler, an assistant professor of plant cell biology at U...

International team shows mercury concentrations in fish respond quickly to increased deposition

A joint Canadian-American research team have, for the first time, demonstrated that mercury concentrations in fish respond directly to changes in atmospheric deposition of the chemical. The international teams research began in 2001 at the Experimental Lakes in Northern Ontario and is featured i...

New study shows fish respond quickly to changes in mercury deposition

Reducing atmospheric mercury emissions should quickly reduce mercury levels in lake fish, according to a three-year study published this week in the Proceedings of the National Academy of Science. The study showed that an increase in mercury loading at rates relevant to atmospheric deposition resu...

Sandia researchers take new approach to studying how cells respond to pathogens

A Sandia National Laboratories research team led by Anup Singh is taking a new approach to studying how immune cells respond to pathogens in the first few minutes and hours of exposure. Their method looks at cells one at a time as they start trying to fight the invading pathogens. Called the...

UCLA: How does your brain respond when you think about gambling or taking risks?

Should you have a surgery that is likely to extend your life but poses some risk that you will not survive the operation? Should you invest in a risky startup company whose stock may soar even though you could lose y...

UCSD study reveals how plants respond to elevated carbon dioxide

An important source of uncertainty in predictions about global warming is how plants will respond to increasing atmospheric carbon dioxide. Now biologists at the University of California, San Diego have made significant advances toward understanding the mechanism plants use to regulate their carbon...

HIV-infected adults in Botswana respond positively to ARV therapy public treatment program

With preliminary results from a study in Botswana, Harvard School of Public Health researchers have found that people with HIV-1 subtype C in resource-poor settings, who receive antiretroviral (ARV) therapy, can achieve comparable results to those in the developed world. A fully supported health ca...

Neurons generated in the adult brain learn to respond to novel stimuli

New brain cells that develop in the olfactory system of adult mice appear to play a role in the brain different from that of older neurons. The new olfactory neurons are especially sensitive to novel stimuli, preferentially learning to respond to new odors. This level of flexibility suggests that...

Bacteria recognize antimicrobials, respond with counter-defenses

Many living things, from fruit flies to people, naturally produce disease-fighting chemicals, called antimicrobial peptides, to kill harmful bacteria. In a counter move, some disease-causing bacteria have evolved antimicrobial detectors. The bacteria sense the presence of antimicrobial peptides as ...

Identification of specific genes predicts which patients will respond to Hepatitis C treatment

For the first time, physicians at University Health Network and University of Toronto have identified a small subset of genes that can predict whether a patient with chronic Hepatitis C will be able to respond to current treatments. These genes could also become the basis of a simple new test in...

Medical molecules designed to respond to visible light that can penetrate tissue

If you have ever covered a flashlight with your hand and seen the red light that still comes through, then you have seen light in the therapeutic window ?that magic wavelength that is not absorbed or reflected away by tissue. Scientists believe that they can use light at that wavelength to signal m...

Plants respond similarly to signals from friends, enemies

Two soil-dwelling strangers ?a friend and a foe ?approach a plant and communicate with it in order to enter a partnership. The friend wants to trade nitrogen for food. The foe is a parasite that wants to burrow in and harm the plant. In a new finding published in Proceedings of the National Acad...
