Vitamin and mineral supplements can enhance mental energy and well-being not only for healthy adults but for those prone to anxiety and depression, according to a July 15 panel discussion at the 2013 Institute of Food Technologists Annual Meeting & Food Expo held at McCormick Place. Fuente :...

People with impaired glucose tolerance -- the precursor to Type 2 diabetes -- often show impaired cognitive function that may be alleviated through a diet designed specifically for their condition, according to a panel discussion at the 2013 Institute of Food Technologists Annual Meeting & Expo....

Researchers at Johns Hopkins have coaxed stem cells into forming networks of new blood vessels in the laboratory, then successfully transplanted them into mice. The stem cells are made by reprogramming ordinary cells, so the new technique could potentially be used to make blood vessels genetically...

Healthy snacks that promote a feeling of fullness (satiety) may reduce the amount of food intake at subsequent meals and limit overall food consumption, according to a presentation today at the 2013 Institute of Food Technologists Annual Meeting & Food Expo in Chicago. Fuente :...

Researchers at the City University of New York and Rutgers University have developed a novel procedure enabling early detection and identification of downy mildew in basil. This simple method, which does not require expensive equipment, is described in the July issue of Applications in Plant...

Sweet and salty flavors, repeat exposure, serving size and parental behavior are the key drivers in children's food choices, according to a July 15 panel discussion at the 2013 Institute of Food Technologists Annual Meeting & Food Expo held at McCormick Place. Fuente :...

On July 16, 2013, at 12:09 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on...

Drought resistance is the key to large-scale production of Jatropha, a potential biofuel plant -- and an international group of scientists has identified the first step toward engineering a hardier variety. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/Z...

Scientists have developed a comprehensive list of genetic variants for each of the types of cells that comprise what is known as the NCI-60 cell line collection. This new list adds depth to the most frequently studied human tumor cell lines in cancer research, molecular pharmacology, and drug discovery. Fuente :...

How do stationary cancer cells get the mutations that allow them to travel through the body to seed metastasis? Do they just grow these mutations themselves? Study shows that cancer cells fuse with blood cells -- which already can travel! -- to create a hybrid, metastatic cancer cell. Fuente :...

A drug targeting a protein complex containing two different types of opioid receptors may be an effective alternative to morphine and other opioid pain medications, without any of the side effects or risk of dependence, according to new research.

Plant-based diets are healthy. Plants are high in flavonoids. So flavonoids are healthy. At least that's the reasoning of many manufacturers of flavonoid-based nutritional supplements. But a new study shows that may not be the case. Flavonoids tested in the study affected the endocrine system in ways that in one case promoted...

Many children develop fevers without an obvious cause. Now, researchers have shown they can tell whether a child has a viral or bacterial infection by profiling the activity of genes in a blood sample. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/j...

Researchers have found that Fiji’s largest marine reserve contains more sharks than surrounding areas that allow fishing, evidence that marine protected areas can be good for sharks. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/j...

Investigadores del instituto suizo ETH Zúrich han desarrollado un método de levitación acústica que permite transportar y manejar materia sin llegar a tocarla. La técnica se basa en la emisión de potentes sonidos y se podría usar para fusionar gotas de material o manipular células. Fuente :...

Un diente de T. rex fusionado entre las vértebras de una de sus presas confirma que este enorme dinosaurio era capaz de cazar a otros dinosaurios aunque, en este caso, la víctima sobreviviera al ataque, tal y como publican hoy paleontólogos estadounidenses en la revista PNAS. Fuente :...

New research provides a rare "picture" of the activity taking place at the single molecular level: visual evidence of the mechanisms involved when a cell transports mRNA (or messenger RNA) to where a protein is needed to perform a cellular function.

Investigadores del Museo Nacional de Ciencias Naturales (CSIC) han identificado la existencia de una segunda apertura al exterior en la Cueva de Altamira (Cantabria). El estudio arroja luz sobre la dinámica atmosférica de la cueva y es esencial para diseñar medidas más eficaces para la conservación...

Las subunidades GluN3A de los receptores NMDA que interactúan con el glutamato podrían ser futuras dianas terapéuticas en la lucha contra el huntington. La corea de Huntington es un trastorno neurodegenerativo progresivo e irreversible, originado por la mutación en el gen que codifica para la...

Endogenous retroviruses (ERVs) are viruses that at some point in the past inserted themselves into the nuclear genome of a host’s germ cell. Once integrated in a germ cell the virus would be passed on from one generation to the next and the endogenous retroviral genome would therefore be inherited...
