Climate change is unlikely to lead to more days of extreme cold, similar to those that gripped the USA in a deep freeze last winter, new research has shown. The Arctic amplification phenomenon refers to the faster rate of warming in the Arctic compared to places further south. It is this phenomenon that has been linked to a...

Researchers have found evidence of widespread refreezing of ice at the bottom of the Greenland Ice Sheet; some of these features coincide with faster flows. The newly revealed forms may help scientists understand more about how ice sheets behave and how they will respond to a warming climate. Fuente :...

With the increase in childhood obesity and the associated increase in type 2 diabetes among children and adolescents, there is growing interest in how children's bodies process the foods they eat and how obesity and diabetes begin to develop at early ages.

A six-year-old Bolivian girl presented with an unusual medical symptom: uncontrollable and inappropriate fits of laughter. “She was considered spoiled, crazy, even devil-possessed,” according to those who knew her. Then medical researchers discovered a hamartoma -- a small tumor pressing on the temporal lobe of her brain....

Researchers have deduced essential biological and genetic information from the genome sequence of the whipworm, an intestinal parasitic worm that infects hundreds of millions of people in developing countries. This information acts as the foundation for the development of new strategies and treatments against this debilitating...

Investigators have found a therapy that reverses new onset type 1 diabetes in mouse models and may advance efforts in combating the disease among humans. There is no cure for Type 1 diabetes though it can be controlled with insulin therapy. Symptoms of the disease include frequent urination,...

The Affordable Care Act (ACA, also known as Obamacare) is dramatically changing health care delivery in the U.S. Specific parts of the new law, which will be phased in through 2020, will have a significant impact on patients with diabetes and prediabetes, as explored in a comprehensive Review...

New research suggests canola oil may be one of the oils of choice for people with Type 2 diabetes. Researchers compared people with Type 2 diabetes who ate either a low glycemic index diet that included bread made with canola oil, or a whole wheat diet known to reduce the risk of cardiovascular...

Los aromas y sabores que se perciben de las plantas se deben principalmente a la presencia de aceites esenciales, sustancias que sirven como materia prima en la industria química o cosmética, ante este panorama el Centro de Investigación Científica de Yucatán (CICY) estudió 20 especies nativas del...

A text message-based self-management intervention improves glycemic control in high risk Latinos with type 2 diabetes, a study shows. The messages in the study focused on healthy nutrition tips, the benefits of physical activity and medication adherence, and requests to check blood sugar and send...

Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time. This could provide a new explanation for the patterns observed in the speed of evolution and has implications for the interpretation of climate models. Fuente :...

Obesity, which affects more than one-third of Americans, is a chronic disease that can shorten one’s life span, but new findings show that its effect on mortality has reduced in recent years among many groups, particularly women. “One of the possibilities our findings suggest, but do not prove, is...

Se estima que a nivel mundial más del 60 por ciento de los bioplásticos se elaboran a partir de fuentes potenciales de alimento, como el maíz o la papa. Por ello y debido a que en México esta industria es incipiente, un estudiante del Instituto Tecnológico y de Estudios Superiores de Monterrey,...

If the icy surface of Pluto's giant moon Charon is cracked, analysis of the fractures could reveal if its interior was warm, perhaps warm enough to have maintained a subterranean ocean of liquid water, according to a new study. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/y...

Scientists have created a new recipe that captures key flavors of the brownish-orange atmosphere around Saturn's largest moon, Titan. The recipe is used for lab experiments designed to simulate Titan's chemistry. With this approach, the team was able to classify a previously unidentified material...

Scientists took a molecular-level journey into microtubules, the hollow cylinders inside brain cells that act as skeletons and internal highways, and watched how a protein called tubulin acetyltransferase (TAT) labels the inside of microtubules. The results answer long-standing questions about how...
