Using artificial intelligence, computational geometry and geo/ultrasound techniques, a project begun in 2009 at the Center for Research and Advanced Studies (CINVESTAV) have a success to report - a device to help people with low vision or blindness to navigate more easily.

The new navigation device consists of glasses with stereo sound sensors, GPS technology and a tablet, which guides the blind person to a specific point and avoids hitting static or moving obstacles - but it also recognizes currency of various denominations and the color of clothing. No more crazy plaids and stripes, no chance of getting cheated in a store.

The laws of physics are absolute - in theory.  And with an exception. So absolute doesn't always mean what we think it means.

How heat and temperature related to energy, the laws of thermodynamics, seem to violate the laws of physics theoretically. But now they theoretically don't.

A paper recently published in EPJ B discussed a theoretical model of the environment's influence on a particle does not violate the third law of thermodynamics, despite appearances to the contrary. These findings are relevant for systems at the micro or nanometer scale that are difficult to decouple from the heat or the quantum effects exerted by their environment.

She will tell you it doesn't matter. But it does, men. It does.

Up to a third of all men have had premature ejaculation - it's all good for them, but a University of Zurich sex researcher says curtailed sexual intercourse without climaxing can be more frustrating for women. Or less. It depends. Women are complicated that way..

Premature ejaculation in men can causes increased psychological strain and stress in women, according to the survey conducted by Andrea Burri, a clinical psychologist at the University of Zurich,  but if men are focused too heavily on controlling ejaculation, they ignore the sexual needs of women and are unable to cater to their individual desires, which can seriously jeopardize the relationship.  See? Complicated.

Some Sun-like stars are 'earth-eaters.' During their development they ingest large amounts of the rocky material from which 'terrestrial' planets like Earth, Mars and Venus are made.

Trey Mack, a graduate student in astronomy at Vanderbilt University, has developed a model that estimates the effect that such a diet has on a star's chemical composition and has used it to analyze a pair of twin stars which both have their own planets.

People attempting to quit smoking without professional help are approximately 60% more likely to report succeeding if they use e-cigarettes than if they use willpower alone or over-the-counter nicotine replacement therapies such as patches or gum, according to a large survey of smokers in England.

The results were adjusted for a wide range of factors that might influence success at quitting, including age, nicotine dependence, previous quit attempts, and whether quitting was gradual or abrupt.

A diet that combines unsaturated fats with nitrite-rich vegetables, such as olive oil and lettuce, can protect you from hypertension, suggests a new study led by King's College London. The findings, published in the journal PNAS, help to explain why some previous studies have shown that a Mediterranean diet can reduce blood pressure.

The Mediterranean diet typically includes unsaturated fats found in olive oil, nuts and avocados, along with vegetables like spinach, celery and carrots that are rich in nitrites and nitrates.

When these two food groups are combined, the reaction of unsaturated fatty acids with nitrogen compounds in the vegetables results in the formation of nitro fatty acids.
