New research findings on avocado consumption, presented as two posters at the IUNS 20th International Congress of Nutrition, in Granada, Spain, suggest that although calorie consumption at dinner was unchanged, inclusion or addition of fresh Hass Avocado to a meal may help to reduce hunger and the...

When it comes to fat, you want the brown type and not so much of the white variety because brown fat burns energy to keep you warm and metabolically active, while white fat stores excess energy around your waist, causing health problems. Researchers at the University of Texas Health Science Center...

We often ignore what we cannot see, and yet organisms below the soil's surface play a vital role in plant functions and ecosystem well-being. These microbes can influence a plant's genetic structure, its health, and its interactions with other plants. A new series of articles in a special section...

The female common market squid -- Doryteuthis opalescens -- may not be so common after all. Researchers at UC Santa Barbara have discovered that this glamorous cephalopod possesses a pair of stripes that can sparkle with rainbow iridescence. These flank a single stripe, which can go from complete...

Pioneering new research from a team of Indiana University Bloomington biologists has shown for the first time that a protein which has been long known to be critical for the initiation of protein synthesis in all organisms can also play a role in the regulation of gene expression in some bacteria,...

As e-readers grow in popularity as convenient alternatives to traditional books, researchers at the Smithsonian have found that convenience may not be their only benefit. The team discovered that when e-readers are set up to display only a few words per line, some people with dyslexia can read more...

Infection with the toxoplasma parasite makes mice fearless in the presence of cats -- to their regret. But how does the protozoan do that? UC Berkeley scientists looked at the effects of three common strains of toxoplasma and found that they remove the fear of cat urine for as long as four months,...

Un artículo publicado hoy en el British Medical Journal afirma que la crisis económica mundial de 2008 podría ser la causa del aumento de las tasas de suicidio en Europa y América, especialmente en los hombres y en los países con mayores niveles de destrucción de empleo. Fuente :...

Researchers have made the first experimental determination of the weak charge of the proton. The results also include the determinations of the weak charge of the neutron, and of the up quark and down quark. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/z...

Can world-saving claims like "not tested on animals" and "phosphate free," help sell bottles of shampoo and bars of soap? A new study proves such statements can make consumers more likely to buy, especially when one's sense of touch is appealed to alongside one's sense of social justice. Fuente :...

Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report. The research compares multiple satellite records of atmospheric temperature change with results from a large, multi-model archive of simulations. Fuente :...

Until now, researchers believed that asthma, allergies, and respiratory infections contributed to disorders that affect children's breathing during sleep. Now a new study demonstrates that, contrary to this belief, viruses alone may be responsible for the seasonal variation seen in children. Fuente...

18/09/2013, New anti-fraud technology based on microscopic laser dots, models that can predict how efficient a drug will be in the bloodstream and materials that could one day be used to mend a damaged eye: these are some of the highlights that will feature at the Royal Academy of Engineering Research Forum on Wednesday 18...

Neither the total nor the core diameters of laser fibers correspond to the advertised laser fiber diameter, revealed a new study investigating lasers used for urological surgery. Furthermore, there are serious differences between manufacturers of fibers with a supposedly equal diameter. Fuente :...

Removing nitrogen from the environment “the natural way” by creating a wetland is a long-term, nutrient-removal solution, more cost effective than upgrading a wastewater treatment plant, but it isn’t necessarily socially beneficial to offer landowners multiple payments for the environmental services that flow from such...
