Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning

...ill any other insects/microfauna and inserted into experimental grassland to enable colonization by AM fungi from the surrounding plants. Twenty mites from the order Collembola, which would view the AM mycelia as food stuff, were introduced to half of the cores. After another four weeks the grassland was exposed ...

Yale participates in global human genome initiative

...forum for sharing research protocols, establishing experimental standards and developing ways to exchange and compare data. The continued interaction is expected to help optimize rapid, genome-wide screening and accelerate drug discovery. The other Global Initiative founding member institutions are the Campbell...

Bare metal stents deliver gene therapy to heart vessels with less inflammation in animal studies

...enosis in the carotid arteries of animals with the experimental stents, compared to control animals with conventional, polymer-coated stents. The researchers used a therapeutic gene that encodes for a protein, inducible nitric oxide synthase (iNOS), in the carotid artery studies, because of iNOS's ability to con...

How Fruitflies Know It's Time for Lunch

...(they wait a while before initiating feeding), the experimental flies started eating new food right away. These hug neurons may help flies decide whether or not to eat a new food source. Larvae express hug in only about 20 neurons, all located in the subesophageal ganglion. The axons of some of these hug neurons...

Compound from marine bacteria shows potential as multiple myeloma therapy

...archers in the November issue of Cancer Cell. The experimental compound, NPI-0052, has been found to block or inhibit cancer cells' proteasomes from working effectively. The proteasome work as a cell's "garbage disposal," chewing up and disposing of old, unwanted proteins. With their proteasome jammed, cells die...

Free-energy theory borne out in large-scale protein folding

...s have successfully combined computer modeling and experimental results in folding studies for small proteins, but...ring efforts were required to establish comparable experimental and theoretical data, and the method worked remarkably well. We expect others to adopt it in their o...

New understanding of regeneration gained by Forsyth scientists

... Institute Department of Cytokine Biology. Through experimental approaches and mathematical modeling, Dr. Levin and his team examine the processes governing large-scale pattern formation and biological information storage during animal embryogenesis. The lab's investigations are directed toward understanding the...

Genetic analysis of cavefish reveals more about evolution

... The replicated experiment is a powerful tool for experimental science, but typically unavailable in the study of evolution. Cave adaptations have evolved in many species independently, however, and each cave species can be considered a replicate of the same evolutionary experiment that asks how species change i...

Do the Europeans turn ill sitting up so late?

Cord blood cells may widen treatment window for stroke

An experimental treatment that spares disability from acute stroke may be delivered much later than the current three-hour treatment standard ?a potential advance needed to benefit more stroke victims. Researchers at the University of South Florida found that human...

Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool

The largest-ever experimental analysis of duplicated genes provides insight into...ng an integrative combination of computational and experimental approaches, they classified duplicate pairs of genes involved in yeast metabolism into four function...

Leading lampreys to slaughter: Pheromone for scourge of Great Lakes identified

...prey nurseries are being used to trap adults on an experimental basis in Michigan streams. "Using these extracts has been shown to work," said Sorensen. "Capture rates are up six-fold." Most lamprey traps have been simple, rather ineffective devices, but now the attractants have opened up many new possibilitie...

Jefferson scientists identify gene defect leading to abnormal skin development and cancer

Most lamprey traps have been simple, rather ineffective devices, but now the attractants have opened up many new possibilitie...

Some good news for the world's poor

...nd 1980s. For both China andIndia, the increase in experimental yield slowed down in the 1990s. "One of the reasons is a lack of agricultural research investment at both the national and international levels," he warns. "The budget of the International Rice Research Institute has also been severely cut in recent...

How E. coli bacterium generates simplicity from complexity

...d a computer model of an E. coli cell based on the experimental results of thousands of previous experiments, some of which were completed decades ago. "The goal of this study was to comprehensively simulate all the possible molecular interactions in a well studied strain of E. coli to gain a global view of the r...

Worms know bad food when they smell it

...od they had found to be safe. With the traditional experimental set-up, where worms migrate toward either of two types of bacteria growing on opposite sides of a lab dish, this was impossible to discern, Bargmann said. Hang Lu, a postdoctoral fellow in Bargmann's lab, used her engineering expertise to design a ...

New technique helps researchers determine amino-acid charge

...ether an amino acid is charged or not. Appropriate experimental benchmarks also had been lacking. All cells have membrane proteins that form channels to allow water and/or ions to pass through. Malfunctions have been linked to such problems as hypertension, abnormal insulin secretion, abnormal heart conditions a...

Study shows combination of immune substances to be safe

This strategy, a form of immunotherapy, is sometimes used to treat melanoma, advanced kidney cancer and other tumors that respond...

ASU researchers 'wire' DNA to identify mutations

... can carry an electrical current. Depending on the experimental conditions, DNA has been previously shown to act as both a conductor and insulator. "We have developed a technology that allows us to wire single molecules into an electrical circuit," said Tao, professor of electrical engineering in the Ira A. Ful...

Carnegie Mellon U. transforms DNA microarrays with standard Internet communications tool

The innovative method combines a new experimental procedure and a new algorithm to identify gene activation captured by DNA microarray analysis with greater sensitivity and specificity. The work holds great promise for vastly improving research on health and disease, according to Ziv Bar-Joseph, ass...
