Genes and genius: Researchers confirm association between gene and intelligence

...performance. Presently, she says it's too early to predict how small changes in the gene might be influencing communication in the brain to affect intelligence, and she says it's nearly certain CHRM2 is not the only gene involved. "Perhaps as many as 100 genes or more could influence intelligence," she s...

Scientists identify a candidate gene for osteoporosis

...trains of mice. However, Mohan and his colleagues predict that changes in the amino acid sequence or alterations in regulatory regions of the DARC gene may lead to key functional changes. "There are interesting differences between African Americans and Caucasians that could be associated with this gene...

Investment level in HIV prevention programs related to HIV incidence in the United States

...d in the mid 1980s when investment levels began to predict incidence. That is, as the nation continued to increase the funding of HIV prevention programs, HIV dropped substantially from 160,000 infections per year to about 40,000 infections per year. In the early 1990s, as the level of investment (adjusted f...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

By 2048 all current fish, seafood species projected to collapse

...ggests that small-scale experiments can be used to predict large-scale ocean change. "Through this research, it became clear to me that we hardly appreciate living on a blue planet," Worm said. "The oceans define our planet, and their fate may to a large extent determine our fate, now and in the future." ...

Proteins may predict lung transplant rejection

Math model predicts cancer behavior

...hen computer simulations like this will be used to predict a tumor's clinical progression and formulate individualized treatment plans. For the last two years, he has headed a major effort to develop the kind of mathematical model for cancer invasion powerful enough for this purpose. The result was published...

New way of tracking muscle damage from radiation

...tes that MRI might one day be able to help doctors predict the amount of long-term damage that radiation may ...dvanced and complex, clinicians must have a way to predict the outcomes--including side effects--on specific patients, according to Matthew Krasin, M.D., assoc...

Hundreds of thousands of viral species present in the world's oceans

...m terrestrial ecosystems. In fact, the researchers predict that the world's oceans hold a few hundred thousand broadly distributed viral species, with some species-rich regions likely harboring the majority of these species. ...

Comprehensive model is first to map protein folding at atomic level

... model that, for the first time, can fully map and predict how small proteins fold into three-dimensional, biologically active shapes. The work could help researchers better understand the abnormal protein aggregation underlying some devastating diseases, as well as how natural proteins evolved and how prote...

Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census

...und are still awaiting discovery. The researchers predict that 75% of discoverable genera will be found within 60-100 years and 90% within the next 140 years. In 1990, Dodson first census paper coincided with his publication of The Dinosauria," the first book to comprehensively depict known dinosaurs. I...

Global changes alter the timing of plant growth, scientists say

...l conditions within the range that climate experts predict may exist 100 years from now--a doubling of atmospheric carbon dioxide; a temperature rise of 2 degrees Fahrenheit; a 50 percent increase in precipitation; and increased nitrogen deposition--as a likely byproduct of fossil-fuel burning. Scientists ...

Researchers link ocean organisms with increased cloud cover and potential climate change

...ties right now in climate models is the ability to predict how clouds would respond to changing particle levels ?whether they originate from humans with air pollution or from biological activity. We can now see very strongly the influence of marine biology on oceanic clouds." Researchers had previously t...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

... the approach a "thought experiment," designed to predict how treating different groups in the population would affect the overall epidemic. "Exclusively treating non-drug users is not a wise approach. It's the least efficient and it's the least effective," said Long. According to the model, treating ...

Gene signature assesses breast cancer outcomes

...re group of 70 that make up a genetic signature to predict outcomes in a separate group of patients from the same institution. To determine whether the 70-gene signature performed better than traditional risk classifiers, scientists from the international consortium TRANSBIG assigned 307 patients to high- a...

RNA map provides first comprehensive understanding of alternative splicing

... this RNA map was valid by asking whether it could predict how Nova would act on RNA transcripts that had yet... "In other words, every transcript that we could predict as a Nova-regulated alternatively spliced RNA fit the prediction of this map," says Darnell. "Half o...

Newly identified biomarker detects and regulates spread of brain tumors

...e able in the future to better define the disease, predict what kind of treatment to use and allow doctors to monitor how well the tumor responds to treatment. "Using proteomic analyses of the CSF of patients with brain tumors, we have identified for the first time that attractin levels are elevated in p...

Novel vaccine shows promise against early-stage breast cancer

...rs, and HER-2/neu, all of which have been known to predict the severity of disease, recurrence and overall survival. Developing novel therapies that target these specific genetic variances may be extremely beneficial in preventing breast cancer for many women. In this study, researchers investigated a p...

Siberian lakes burp 'time-bomb' greenhouse gas

... byproduct of decomposition." "Permafrost models predict significant thaw of permafrost during this century, which means that yedoma permafrost is like a time bomb waiting to go off - as it continues to thaw, tens of thousands of teragrams of methane can be released to the atmosphere enhancing climate warm...

End of deforestation in view? Experts advance new way to size up global forest resources

...s either the USA or China." The authors also predict the share of industrial wood production in forest plantations will grow from an estimated one-third today to half by 2025 and three-quarters by 2050. "Plantations and the trade to make them effective reduce the impact of industrial pressures on ...
