The mysterious bias of life on Earth toward molecules that skew one way and not the other could be due to how light shines in star- and planet-forming clouds, researchers say.
Nearly all the water present in Jupiter's upper atmosphere today comes from the comet Shoemaker-Levy 9, which collided with the planet in July 1994. Using ESA's Herschel telescope, the discovery was made by an international team of astronomers led by a researcher from the Laboratoire d'Astrophysique de Bordeaux (CNRS/Université Bordeaux 1). It is published in the journal Astronomy and Astrophysics dated 23 April 2013.
New research published in the journal Nature Geoscience has revealed how Saturn keeps itself looking young and hot
As planets age they become darker and cooler. Saturn however is much brighter than expected for a planet of its age - a question that has puzzled scientists since the late sixties. New research published in the journal Nature Geoscience has revealed how Saturn keeps itself looking young and hot.
Saturn's icy moon Enceladus is emerging as the most habitable spot beyond Earth in the Solar System for life as we know it. "It has liquid water, organic carbon, nitrogen [in the form of ammonia], and an energy source," says Chris McKay, an astrobiologist at NASA's Ames Research Center in Moffett Field, California. Besides Earth, he says, "there is no other environment in the Solar System where we can make all those claims.".
If there are extraterrestrial rewards for perseverance, the organisers of the UFO conspiracy hearings that are under way at the National Press Club in Washington this week deserve a visit from space.
In February 2012, the Nobel Prize-winning physicist Frank Wilczek decided to go public with a strange and, he worried, somewhat embarrassing idea. Impossible as it seemed, Wilczek had developed an apparent proof of “time crystals” — physical structures that move in a repeating pattern, like minute hands rounding clocks, without expending energy or ever winding down. Unlike clocks or any other known objects, time crystals derive their movement not from stored energy but from a break in the symmetry of time, enabling a special form of perpetual motion.
Imagine if this Swedish invention were to become a part of stop-and-frisk. US News and World Report writes:
The ruse is common in James Bond movies—an attractive female saunters in at a critical moment and seduces the otherwise infallible protagonist, duping him into giving up the goods.
Children born outside the United States have a lower risk of asthma, skin and food allergies, and living in the United States for a decade or more may raise the risk of some allergies, said a study Monday.
The research in the Journal of the American Medical Association suggests that certain environmental exposures could trigger allergies later in life, overcoming the protective effects of microbial exposure in childhood.
If we’re finished obsessing about yoga jeans, perhaps it’s time to think about yoga and genes.
Newly published research from Norway suggests that a comprehensive yoga program rapidly produces internal changes on a genetic level. The results help explain the well-documented health benefits of this ancient practice.
Researchers have solved the riddle of how one of Africa's greatest civilisations survived a catastrophic drought which wiped out other famous dynasties. Geomorphologists and dating specialists from The Universities of Aberystwyth, Manchester, and Adelaide say that it was the River Nile which made life viable for the renowned Kerma kingdom, in what is now northern Sudan.
Kerma was the first Bronze Age kingdom in Africa outside Egypt.
Their analysis of three ancient river channels where the Nile once flowed shows, for the first time, that its floods weren't too low or too high to sustain life between 2,500 BC and 1,500 BC, when Kerma flourished and was a major rival to its more famous neighbour downstream.
Amy Meyer wanted to see the slaughterhouse for herself. She had heard that anyone passing by could view the animals, so she drove to Dale Smith Meatpacking Company in Draper City, Utah, and from the side of the road she could see through the barbed-wire fence. Piles of horns littered the property. Cows struggled with workers who tried to lead them into a building. And one scene in particular made her stop.
Europe will enforce the world's first continent-wide ban on widely used insecticides alleged to cause serious harm to bees, after a European commission vote on Monday.
The suspension is a landmark victory for millions of environmental campaigners, backed by the European Food Safety Authority (EFSA), concerned about a dramatic decline in the bee population. The vote also represents a serious setback for the chemical producers who make billions each year from the products and also UK ministers, who voted against the ban. Both had argued the ban would harm food production.
More than 160 researchers across 10 European countries joined together, in what is being hailed as the first international project to focus on ocean acidification and its consequences.
According to the partners in the EPOCA project ('European Project on Ocean Acidification') marine research was a relatively new field when they initiated the project four years ago. It brought together scientists who were concerned about the possible risks associated with ocean acidification for marine organisms and ecosystems.
MIND reading can be as simple as slapping a sticker on your forehead. An "electronic tattoo" containing flexible electronic circuits can now record some complex brain activity as accurately as an EEG. The tattoo could also provide a cheap way to monitor a developing fetus.
The most massive neutron star known and its tightly orbiting companion, a wimp of a white-dwarf, have provided one of the most extreme tests yet of Einstein's theory of general relativity.
The theory has again passed with flying colors – for now.
Although the theory has cleared test after test over the past century, researchers keep trying to find its limits. They don't think it's wrong, just incomplete.
SCHRÖDINGER'S cat, both dead and alive at once, was always meant to be a thought experiment, but will ordinary objects or your favourite feline ever enter the quantum world? No one knows, but now there is a way to measure how close physicists are to realising the thought experiment.
The laws of quantum mechanics should apply to everything, from the tiniest particle to the entire universe. However, their effects are usually too small to see on everyday scales. Physicists are continually testing quantum effects at increasing scales, to probe the divide between the classical and quantum realms. But without a ranking system it wasn't clear how far they had got.
Kids like to taunt each other with the cry, "Last one there is a rotten egg!" In Earth's case, that might be more true of the first ones there, according to a new study suggesting that millions of years ago, the planet emanated such a stench.
Mercury, traveling in its 88-day-long orbit around the Sun with basically zero axial tilt, has many craters at its poles whose insides literally never see the light of day. These permanently-shadowed locations have been found by the MESSENGER mission to harbor considerable deposits of ice (a seemingly ironic discovery on a planet two-and-a-half times closer to the Sun than we are!*).
BERLIN — Nets, harpoons and killer robots could become weapons of choice to hunt down the space junk threatening crucial communications satellites currently in orbit round Earth, scientists said Thursday.
Even lasers that act like "Star Trek" tractor beams were among the proposals put forward to protect some $100 billion worth of satellites from man-made cosmic garbage.
