Lower levels of blood sugar may make married people angrier at their spouses and even more likely to lash out aggressively, new research reveals. Researchers found that levels of blood glucose in married people, measured each night, predicted how angry they would be with their spouse that evening.

The local government of Gothenburg, Sweden, is to begin a yearlong experiment to see if cutting the working week to 30 hours will be more efficient. It is hoped working less hours will cut down on sick leave, and save money.
Beards are everywhere these days. From the urban lumberjacks of Brooklyn to the hirsute hackers of San Francisco, men’s faces have taken a turn for the hairy. But according to one theory of evolutionary population dynamics, the look is destined to die down because of its own popularity. And now an experiment involving 3 dozen bearded men lends credence to the prediction.
Can we sense the future before it happens? That question was at the heart of a set of nine experiments that sparked widespread controversy and debate when Professor Daryl Bem published his results in the Journal of Personality and Social Psychology in 2011. The reason: Bem's results were positive, suggesting that we can in some way do the seemingly impossible, and somehow 'know' (precognition) or 'feel' (presentiment) things before they even occur.
Internal damage in fiber-reinforced composites, materials used in structures of modern airplanes and automobiles, is difficult to detect and nearly impossible to repair by conventional methods. A small, internal crack can quickly develop into irreversible damage from delamination, a process in which the layers separate. This remains one of the most significant factors limiting more widespread use of composite materials.
"The history of materials is a history of mistakes," says Mark Miodownik, a materials scientist at University College London, who traces his own fascination with materials to the moment he was stabbed in the back with a razor while ambling to school one day.
The existence of exotic hadrons — a type of matter that doesn't fit within the traditional model of particle physics — has now been confirmed, scientists say.
Astronomers believe that Pluto and its moon were the result of two massive objects slamming into each other. The resulting gravitational dynamic may have warmed the interior of Pluto, creating an ocean comprised of liquid water. Remarkably, this underground sea could still be there.
The soil on Mars may be suitable for cultivating food crops – this is the prognosis of a study by plant ecologist Wieger Wamelink of Wageningen UR. This would prove highly practical if we ever decide to send people on a one-way trip to the red planet. After all, if we are going to live anywhere in outer space in the future Mars stands a good chance of being the place.
Consider a pair of brothers, identical twins. One gets a job as an astronaut and rockets into space. The other gets a job as an astronaut, too, but on this occasion he decides to stay home. After a year in space, the traveling twin returns home and they reunite.
Congratulations! It’s a baby… moon? A bright clump spotted orbiting Saturn at the outermost edge of its A ring may be a brand new moon in the process of being born, according to research recently published in the journal Icarus.
It is the stuff of gothic science fiction: men in white coats in factories of blood and bones.
A Chinese herb called thunder god vine works better than a widely-prescribed pharmaceutical drug at easing rheumatoid arthritis, a new study has found.
A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work. Scientists have demonstrated that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.
Solar power in the desert has problems: big land use requirements, and the need for scarce water to clean the panels and suppress dust. In an unrelated story, biofuels production has problems: life cycle greenhouse gas emission issues, and land use questions again. How about solving both sets of problems at once? Stanford researchers have modeled the co-location of solar panels with agave plants used to make ethanol, and found it to be a winning combination.
Light-absorbing glow-in-the-dark road markings have replaced streetlights on a 500m (0.3 mile) stretch of highway in the Netherlands.
In response to ever-crowded urban conditions in developing countries, researchers in Egypt have developed an inexpensive way of re-directing natural sunlight into dimly lit streets and alleys, where lack of sun is linked to health problems. The new optical device can increase brightness in alleyways by up to 400 percent.
What's your lucky number? An online survey threw up a hot favourite: people find 7 clever, cheery, divine. And our reactions to numbers shine a fascinating light on how our brains work, especially in the oh-so-superstitious far east.
