Virtual animal shelters ?How the Internet is transforming the experience of pet adoptions

...to function as a shelter without having a physical location where the work is done," Garcia says. "Because potential adopters can view photos and descriptions of dogs over the Internet, they can pre-screen them and decide which specific dogs they want to visit in person. The Internet thus has had a profound e...

Sugar helps control cell division

...ook at what it's modifying, and the extent and the location of the modification." The sugar seems to modify as many proteins as the ubiquitous phosphate groups widely recognized as protein controllers, and it frequently seems to compete with phosphate groups for the same spots on proteins. Hart suggests that...

UQ researcher tracking key to healing the brain

...e us to determine, for the first time, the precise location and prevalence of neural stem cells in situ, which in turn will allow us to determine more rapidly and accurately the role played by stem cells in the mammalian brain and spinal cord under normal conditions and following injuries." He said at the m...

New bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity

... able to develop a set of rules for predicting the location of binding site combinations based on limited bind...e regulation, the approach was able to predict the location of regulatory sites for about one-third of the genes in the yeast genome - a success rate as good as...

A vaccine to kill tapeworm

...cysticercosis. Its symptoms vary depending on the location and number of what are called cysticerci. Many people have no serious symptoms, but some go blind, become confused, suffer difficulty with balance or have epileptic seizures. Heavy infections can kill, often as a result of inflammation after the para...

Gene controlling circadian rhythms linked to drug addiction

...e, demonstrated by their strong preference for the location where the drug was administered. In addition, Clock-deficient mice produced more dopamine than control mice did, suggesting that the gene controlling circadian rhythms is a key regulator of the brain's reward system and may influence the addictive p...

For first time, brain cells generated in a dish

...titute and senior author of the paper. Its general location was known, but it was an obscure species in a sea of cell types. "We've isolated for the first time what appears to be the true candidate stem cell," said Steindler, a neuroscientist and member of UF's Program of Stem Cell Biology and Regenerative M...

Fundamental discovery -- Bone fracture

...on images of bone ever published, which reveal the location of the adhesive or "glue" that holds together mineralized collagen fibrils (protein fibers) of bone. The glue appears to contain "springs" that uncoil when the bone is stressed, helping the bone to absorb shock. When the stress is relaxed, they coil...

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

... tick-borne flaviviruses by examining the role and location of NS5 in Powassan virus. Powassan virus, found in North America, Russia, China and Southeast Asia, rarely infects people but is potentially fatal. If the research group can track the movement of NS5 in Powassan-infected cells and learn how it intera...

Siberian tigers hang tough

...ks of a single individual. Researchers map out the location of all these tracks, and then estimate a minimum number of tigers, based on their size and distribution. Dale Miquelle, Director of the Wildlife Conservation Society's (WCS) Russia Program, and overall coordinator for the project, remarked, "This ti...

Scientists track stealth DNA elements in primate evolution

...gh an RNA intermediate, and inserting into another location in the genome. Over evolutionary time, this retrotransposition activity has led to the generation of over one million copies of Alu elements in the human genome, making them the most abundant type of sequence present. Because Alu elements are so abun...

New protein vital for immune response is found in surprise location

...nfections but also has been found in an unexpected location within the cell, causing researchers to rethink previous notions about the workings of the human immune system. Researchers at UT Southwestern Medical Center said their findings may lead to new therapies aimed at preventing and treating viral diseas...

Scientists to mimic nature for newest cancer drugs

...inimize the risk of ship strikes -- mandatory ship location reporting, extensive aerial survey efforts and mariner education -- the scientists say that the initiatives don't lead to a reduction in ship strike mortalities without required changes in the operation of ships within right whale habitats and migrat...

FSU scientist warns North Atlantic right whale facing extinction

Such circadian clocks govern the approximately 24 hour activity and metabolic cycles of animals from the simplest insects to humans. Reppert and his colleagues found that key genes responsible for the cl...

International Team Determines Geographic Origin of Leprosy

... close correlation between SNP type and geographic location of the leprosy patient. Type 2, predominant in a small region of East Africa and Central Asia, is the rarest and oldest, the scientists believe. Type 1, present in Asia and the Pacific region, represents the eastward migration of leprosy, while type ...

Biologists determine genetic blueprint of social amoeba

...somes of Dictyostelium. The scientists mapped the location of several hundred genes on those chromosomes based on landmarks that had been discovered over the years, then created a set of 5,000 large DNA clones, each about 200,000 nucleotide bases long, that proved useful for other researchers in assembling t...

Improved statistical tools reveal many linked loci

...genetic factors, even though more than one genetic location contributes to the observed trait, such as blood pressure or cell growth. The new statistical method bypasses the previously overwhelming computations needed to puzzle together the myriad elements that influence gene expression throughout an entire ...
