Study casts doubt on 'Snowball Earth' theory

...0 to 600 million years ago. They disagree over the severity of the glaciation. "Snowball Earth" proponents, who say that Earth's oceans were covered by thick ice, explain the survival of life by hypothesizing the existence of small warm spots, or refugia. On the other side are supporters of a "Slushball Ear...

Neurologix announces positive results of gene therapy clinical trial in Parkinson's disease

...ing (ADL), another standard measure of Parkinson's severity which is recorded by the patients themselves, showed a strong trend toward statistical improvement(p= .06). In addition, fluorodeoxyglucose (FDG)-PET scans at one year revealed that the treated side of the brain exhibited a statistically significant...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

...researchers noted a direct association between the severity of the infection and greater loss of brain matter. In methamphetamine abusers who are also HIV-positive, decreased volumes are correlated with increased cognitive impairment in one brain region, the hippocampus. Dr. Jernigan explains that the chang...

Swimming with dolphins can alleviate depression

...participants dropped out of the study, the average severity of the depressive symptoms was more reduced in the experimental group than in the control group. Animal facilitated therapy with dolphins is more effective than water therapy in treating people with mild to moderate depression, say the authors. Des...

Building a better mouse model of lung cancer: FHIT counts

...op were larger and more numerous. In addition, the severity of the tumor growth appeared to follow a continuum paralleling the loss of the protein. While the normal mice developed only benign tumors, 17 percent of the mice that had lost one copy of the gene developed malignant tumors and all of the tumors in ...

Shorter colds, milder flu may follow from newly revealed immune mechanism

The ability to decrease the severity of lung infections may also have important implications for asthma, COPD (chronic obstructive pulmonary disease) and other chronic lung diseases, according to Holtzman. "We commonly see children, for example, who develop these same types of severe ...

New drug could reduce tissue damage after heart attack

... has previously shown that human CRP increases the severity of damage in experimental models of heart attack and stroke. This first identified CRP as a valid therapeutic target. The present collaborative study has now rationally designed a potent small molecule inhibitor of CRP. The new compound, bis(phosph...

They add, "In the rural part of central Anatolia, Turkey, millions of inhibitants are likely exposed to hazardous amounts of mineral fibers from the environment. Res...

Scientists develop malaria forecasting tool to predict disease risk

...untries, which could then be used to calculate the severity of an epidemic, months before its occurrence." The team created a prediction system using seven, state-of-the-art, global climate models which produce weather forecasts up to six months in advance. The system allows researchers to assess the proba...
