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

... resistance proteins from disappearing, while SGT1 helps them disappear. The result is that the system remains poised for an immediate response to bacteria and other attackers. "By controlling disappearance of resisting proteins, RAR1, HSP90 and SGT1 control whether or not the plant is about to recognize ...

Researchers extend mouse lifespan by protecting against free radicals

...heir study on catalase, an enzyme in the body that helps convert hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of metabolism and it can be a the precursor of free radicals that can damage the cell. The damage can in turn lead to more flaws in the cell's chemical processes, m...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

... highly electrically conductive. This breakthrough helps describe how microorganisms can clean up groundwater and produce electricity from renewable resources. It may also have applications in the emerging field of nanotechnology, which develops advanced materials and devices in extremely small dimensions....

Malaria killing a million a year

... but it makes sense that my first public statement helps make the case for fighting a largely preventable and utterly treatable disease," Executive-Director Ann Veneman said in New York. "It is a disease that kills one child in sub-Saharan Africa every 30 seconds. The numbers are astounding -- and unaccept...

Novel compounds show promise as safer, more potent insecticides

..., which block acetylcholinesterase, an enzyme that helps control nerve activity. Some experts are concerned that these older, less-selective insecticides could pose heath risks and there’s a growing effort underway to find safer replacements. Targeting the ryanodine receptor may offer a promising alternat...

Major advance made on DNA structure

...elationship to genetic sequences, researchers say, helps set the stage for applied advances in biology, biomedicine, genetic engineering, nanotechnology and other fields. The recent work was supported by grants from the National Institutes of Health and the National Science Foundation. ...

Compound might defeat African sleeping sickness, clinical trial beginning this month

...stage," the physician said. "When a drug works and helps a lot of people, that's when all our hard work really pays off, and we can be proud of our efforts." Three years ago, the National Foundation for Infectious Diseases presented its Jimmy and Roselyn Carter Humanitarian Award to Bill and Melinda Gates...

Scientists focus on 'dwarf eye'

...caused by an alteration in a gene called MFRP that helps control eye growth and regulates the organ's shape...ium (RPE), which is located beneath the retina and helps maintain photoreceptors, the eye's light-detecting cells. Blindness occurs when these cells die afte...

Gene therapy advance treats hemophilia in mouse models

...s liver-specific," McCray said. "This modification helps prevent negative side effects. For example, if the gene were expressed in immune cells instead of liver cells, it could lead to a damaging immune response." McCray said the team now is studying additional ways to make the hybrid vector express the p...

A molecule impedes the destruction of the 'Brucella' bacteria

...ty of Navarra has shown how a determinate molecule helps an important pathogen, Brucella abortus, escape destruction within the cells charged with eliminating infectious agents (macrophages). This research has been published in Nature Immunology scientific magazine. Brucella is a model of an intracellular...

Expanding forests darken the outlook for butterflies, study shows

Genetic discovery could lead to drought-resistant plants

...nior author Malcolm Campbell. "This is a gene that helps regulate carbon dioxide uptake. If plants are the Earth's lungs, we've just discovered a key piece of information about how the Earth breathes." The pores on the surface of plant leaves, called stomata, function like little mouths that open and clos...

Elderly mice yield clues to the process of growing old

... resides outside of the nucleus of a cell and that helps power critical cell processes. Such insight could also lead to strategies to restore some functions such as hearing by protecting mitochondrial DNA from naturally occurring mutations. Using mice genetically altered to have a deficiency in a protein...

'Sinkers' provide missing piece in deep-sea puzzle

... Institute (MBARI) recently published a paper that helps answer this question, at least for animals that live on the deep seafloor off the coast of Central California. After analyzing hundreds of hours of deep-sea video, Bruce Robison and his colleagues found that "sinkers"-the cast-off mucus nets of small...

Modification of program enables prediction of gene transcription

...u can learn something about one of the choices, it helps you with the other one," Brent said. "By making this integrated model that looks for both kinds of exons in both parts of the gene, we're able to convert a blind guessing game to a multiple choice question ?is it a UTR exon or a protein-coding exon? ...
