Cardiologist's 'living chip' changes science of disease monitoring

...scheduled testing at a routine visit. Catching the problem earlier means the patient remains healthier, and greatly lessens the chance of a hospital stay. The initial application for this technology is expected to involve pharmaceutical companies, which could use the biological chips to test potential drug...

Coral reefs are increasingly vulnerable to angry oceans

... "Our study offers a solution to this longstanding problem by factoring in the shape of different coral colon...orals' cells to become toxic, or bleached. Another problem is overfishing, which can deplete the fish that eat dead coral and keep the reef clear for the next ...

Dinosaurs -- stones did not help with digestion

...ave a toothless beak, such as ostriches, solve the problem with what is known as a gastric mill. Their muscular stomach is equipped with a layer of horn and contains stones which help to break up, crush and thereby also to digest food. Giant dinosaurs from the Jurassic and Cretaceous period (200 million t...

Serengeti patrols cut poaching of buffalo, elephants, rhinos

...s confounds efforts to learn how best to solve the problem when wildlife numbers decline catastrophically. So Hilborn and his co-authors employed the catch-per-unit-of-effort technique used for decades by managers to estimate fish abundance and set fishing limits. Estimates are based on a ratio comparing ...

Gene therapy research switches off joint inflammation; switches on genetic process of joint repair

...has plagued researchers for decades and corrects a problem that is exacerbated with aging. Multi-center, Randomized controlled Clinical Trial Underway Dr. Mark J.S. Miller said that, "This trial is important because it directly compares Reparagen with glucosamine in treating subjects with moderate oste...

Search on for treatment of slow-healing wounds

...people from different disciplines they can see the problem in different ways," James said. "The more minds working on a problem, the better." The NIH grant will represent the largest single medical research project at the center. "The ultimate goal," James said, "is to heal people's wounds, save their l...

On the golf tee or pitcher's mound, brain dooms motion to inconsistency

... It's as if each time the brain tries to solve the problem of planning how to move, it does it anew, Churchla...Practice and training can help the brain solve the problem more capably, but people and other primates simply aren't wired for consistency like computers or ma...

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

... those who frequent tennis courts, but is a common problem for people whose activities require strong gripping or repetitive wrist motions. It is a degeneration of the tendon above the elbow that controls the movements of the wrist and hand. Treatments such as rest, nonsteroidal anti-inflammatory drugs, br...

A simple feedback resistor switch keeps latent HIV from awakening

...low level of erroneous transcription. This poses a problem for the virus--how does it prevent stray transcrip...tivation? Certain bacterial viruses manage this problem by encoding intricate repressor circuits that efficiently block transcription. But animal viruses, s...

Steep oxygen decline halted first land colonization by Earth's sea creatures

...An unshelled mollusk has a far greater respiratory problem than a shelled mollusk," Ward said. "In many groups the shell is an active part of the respiratory system." ...

'Mindless autopilot' drives people to underestimate food decisions

...ood decisions are made on mindless autopilot." The problem with making so many more food decisions than we are aware of, he said, is that "each of these small decisions is a point where a person can be unknowingly influenced by environmental cues." When Wansink and Jeffery Sobal, Cornell professor or nutri...

Female pronghorns choose mate based on substance as well as show

... tail, as cues that females might use. The thorny problem has been to explain how the correlation between male genetic quality and ornament quality can be maintained. If an ornament gives a male a mating advantage, then evolution would rapidly move to the point where all males, regardless of genetic quality...

Stormy days ahead for coral reefs

... "Our study offers a solution to this longstanding problem by factoring in the shape of different coral colonies, the strength of the sea-bed to which they attach and the change in force of the waves as they move across the reef. "This enables us to predict the likely changes in composition of the coral...

USC team reveals structure of APOBEC family protein

Resistant bacteria increasing source of muscle infection

...she said, they have not yet determined whether the problem is this specific gene or another that is close to it. Others who participated in this research include: Drs. Kristina G. Hulten, Blanca E. Gonzalez, Edward O. Mason, Jr., and Sheldon L. Kaplan, all of the section of infectious diseases in the depa...

Bacterial protein shows promise in treating intestinal parasites

...matode infections, which are a major global health problem in developing countries. Many of the nearly two billion people worldwide infected with these intestinal parasites are children, who are at particular risk for anemia, malnutrition and delayed growth. The UCSD-Yale team found that a protein produce...

Key gene controlling eye lens development identified

...ye normally forms. The St. Jude team overcame this problem by taking advantage of Cre/loxP-technology, which allowed them to choose the time and place in which to remove Six3 function from specific cells. This permitted the investigators to remove Six3 activity from the presumptive lens ectoderm (PLE)--the a...

...ers react to the technology." He added, "It's a problem that is ecologically complex. We cannot say, 'Because it's good in Arizona that it will necessarily be good somewhere else.' We need to study many systems carefully before we can generalize." ...

Immune cell communication key to hunting viruses, Jefferson immunologists show

... a novel "biosensor" to solve in part a perplexing problem in immunology: how immune system cells called killer T-cells hunt down invading viruses. They found that surprisingly little virus can turn on the killer T-cells, thanks to some complicated communication among so-called "antigen presenting" protei...
