Natural selection at single gene demonstrated

...ed annually. But two versions of FRI that appeared thousands of years ago enabled the plant to flower year-round, helping it out-compete other plants. Toomajian and his group showed that these two versions, also called gene variants, are too common to have spread solely by chance. "We've shown that for one g...

Unique equine cataract surgery offered on routine basis

... on a routine basis, which could save the sight of thousands of horses. Professor Derek Knottenbelt from the University's Division of Equine Studies and Professor David Wong from the Ophthalmology Research Unit, have developed a unique approach to cataract removal operations combining techniques used on hum...

...izing life at a molecular level ?life that existed thousands of years ago. Ostrom's work has spanned from examining organic matter in meteorites to reconstructing who eats who in the food web from the tropics to the arctic. The trail is laid by stubbornly durable molecules. She uses mass spectrometry, an anal...

Spring migration of pink-footed geese under threat

As thousands of pink-footed geese (Anser brachyrhynchus) prepare for their spring migration north to breeding grounds in the Arctic, ecologists are warning that the escalating conflict between farmers and the geese is threatening the birds' survival. Writing in t...

...which turns the cell into a factory to manufacture thousands of copies of the virus." One result is the disease infectious mononucleosis ?called the "kissing disease" because EBV is transmitted in saliva ?whose symptoms resemble that of a cold. But in rare cases activation of the virus also leads to EBV asso...

International HIV/AIDS trial finds continuous antiretroviral therapy superior to episodic therapy

...on among hundreds of dedicated AIDS clinicians and thousands of their patients, all of whom should be commended for their exceptional achievement in contributing to this pivotal HIV/AIDS treatment study." "This trial was designed to help physicians and their HIV-positive patients identify the best approach to...

Virginia Tech helping to develop higher quality, disease-resistant wheat varieties

... work with USDA genotyping laboratories to provide thousands of molecular analyses required to deploy the targeted genes into breeding lines. The genetic information will be stored in national databases and seed stocks deposited in USDA's Small Grain Collection, providing long-term public access to genetic in...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

"The cells have the ability to expand, or multiply, under controlled conditions, and the expanded cells have the ability to develop into different types of cells in the appropriate environment. One donation can produce billions of MSCs....

Scientists discover that widely available drug also helps fight kidney disease

...of kidney cells, which results in the formation of thousands of cysts that eventually destroy the kidney. Fortunately, a highly effective inhibitor of mTOR is well known. This drug, rapamycin, was originally discovered in the 1970s in soil from Easter Island. It is used for immunosuppression in kidney transpl...

Utah researchers confirm chromosome may harbor autism gene

Using technology that allows DNA from thousands of genes to be collected and surveyed on a 3 x 1½-inch chip, University of Utah medical researchers have confirmed that a region on a single chromosome probably harbors a gene that causes autism. The researchers at the U School of Medicine made the f...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

The largest such effort is Venter Institute's Sorcerer II Expedition, for which sequencing is funded by the Moore Foundation. The Expedition is developing the first large-scale genomic survey of microbial life in the world's oceans to pro...

Protein 'nanosprings' most resilient found in nature

... at the other end with the AFM cantilever. "After thousands of stretches, a pattern emerged," Marszalek said. "The molecule exhibited linear elasticity--a property that had never been seen in any other protein." The ankyrin repeats act like linear springs, meaning that their tension is directly proportional ...

Brain differences could explain why males and females experience pain relief differently

...cting on these brain regions. Interestingly, while thousands of studies have been conducted examining the role of the PAG and the RVM in pain and analgesia, these studies were conducted exclusively in males. The study by Murphy is the very first to examine if these brain regions are organized anatomically in ...
