Soils offer new hope as carbon sink

...research scientist Dr Lukas Van Zwieten said soils naturally emit about 10 times more greenhouse gas on a global scale than the burning of fossil fuels. "So it is not surprising there is so much interest in a technology to create clean energy that also locks up carbon in the soil for the long term and lifts...

Modeling the restless brain

...ow 5- to 10-second fluctuations of activity emerge naturally from much faster, chaotic neural interactions that typically last only a few milliseconds. "Our model suggests that the cortical resting state is not time-invariant, but instead contains rich and interrelated temporal structure at multiple time s...

How sneaky HIV escapes cells

...rs that cells make HIV and other retroviruses by a naturally occurring export mechanism,” says Stephen Gould, Ph.D., Professor of Biological Chemistry at Johns Hopkins. Cells normally export certain membrane-bound molecules to the outside world by means of small sacs known as exosomes. By studying human T-cell...

How to lose weight and not go hungry: HU researcher develops drug that mimics feeling of 'fullness'

...veloped a compound that mimics the activity of the naturally occurring hormone called aMSH. This hormone is naturally excreted during eating and binds to a receptor in the brain called MC4R. When this “communication” o...

Pesticides choke pathway for nature to produce nitrogen for crops

...s alfalfa and soybeans require such interaction to naturally replace nitrogen levels that, in turn, benefit primary market crops like corn grown after legume rotations. __IMAGE_2 Legume plants secrete chemical signals that recruit the friendly bacteria, which work with the plants to convert atmospheric n...

Newly discovered antibody may be body's natural defense against Alzheimer's

...pital/Weill Cornell Medical Center have identified naturally occurring antibodies in human blood that may help to defend against this form of dementia as well as other neurodegenerative diseases. The newly found antibodies selectively target aggregates of beta amyloid proteins called "oligomers" that are tox...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

...t,” explained McGraw, who studies the functions of naturally occurring chemicals in birds and their relationship to the birds’ colors and health. “In the case of the zebra finch, the cost is in the pigments – having enough of them to develop a red beak and enough to combat testosterone, which you also need...

Study shows lizard moms dress their children for success

...rds captured in the wild and found a wide range of naturally occurring estradiol concentrations in the egg yolks. The researchers then performed experiments in breeding enclosures, each holding one male lizard and three females. The numbers of orange- and yellow-throated females in each enclosure were expe...

Microbes at work cleaning up the environment

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...irefly's glow," Akin said. Certain bacteria are naturally programmed to dissolve vesicle membranes, a critical step to delivering the cargo. The nanoparticles are referred to as "smart" because they release their cargo at precisely the right moment after entering the cell. "At the same time that the bact...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

A naturally occurring molecule in the body appears to control whether certain medications, such as beta adrenergic receptor agonists used in acute heart failure or in inhalers for asthma, lose their effectiveness over time. Nitric oxide is a molecule produced b...

DNA repair proteins monitored at double-strand break

...he researchers used an enzyme called I-PpoI, which naturally seeks certain DNA areas to cut. The investigators modified I-PpoI so that they could better control when the enzyme moves into the nucleus and cleaves the DNA. The team then used a biochemical technique called chromatin immunoprecipitation to collect...

'Short-circuit' found in ocean circulation

...of a unique signal - the spread of helium released naturally from the Earth’s interior at deep vents in the Pacific. The helium dissolves in the deep sea and a plume of this marked water travels down the coast of Chile. It is injected at depth into the Antarctic current on the Pacific side of Cape Horn. It...

Hives ferment a yeasty brew, attract beetle pest

...s are also aided in their invasion by a yeast that naturally occurs on pollen and produces, as a fermentation product, the alarm chemical that draws the beetles. "It is possible that bees are being habituated to a low level of alarm hormone," says James H. Tumlinson, the Ralph O. Mumma Professor of Entomolo...

Deconstructing brain wiring, one neuron at a time

...rons, identifying them one by one. Viruses that naturally spread between neurons have previously been used to outline the flow of nerve cell communication, but they have two drawbacks. First, once inside the brain, they keep spreading from cell to cell without stopping. Second, they cross different synapses...

Using nanomagnets to enhance medical imaging

...ty is not believed to be an issue, because iron is naturally found in the body and other studies have found that these materials are non-toxic at the concentrations used in MRI. NIST works with Florida State University to make single-molecule magnets less than five nanometers (nm) in diameter, and works wit...

Hybrid molecule causes cancer cells to self-destruct

...earchers discovered that butyrate, which is formed naturally at high levels in the digestive system by symbiotic bacteria that feed on fiber, can restore healthy cell functioning. Efforts to use butyrate as a general drug for tumors elsewhere in the body, however, have been hindered by the high doses of th...

Anthrax attack posed greater potential threat than thought

... few studies of the immune response to high-level, naturally occurring anthrax exposure in humans, and may be the first to describe cell-mediated responses to this pathogen." Dr. Hadler said that the study's data suggest that cell-mediated responses in B. anthracis infection may be more sensitive than antibody...
