Stunning evidence has emerged that the Earth avoided a cosmic bullet that could have wiped out the entire human race less than 130 years ago. A new study done at the Universidad Nacional Autónoma de México revealed the amazingly close counter.
It's name is Eta Carinae. It's a star—or to be absolutely accurate—a binary star. And it's getting ready to destroy anything within 50,000 light years of it...like Earth. Although few have ever heard of Eta Carinae, if things go wrong—horribly wro
Unlike previous attempts in which scientists tried to measure the transition temperature directly, the CNR team "snuck up" on the answer by inferring the temperature from a thorough study of the dynamics of water. They examined water's behavior in
I then remembered about a giant Indian that is on the roof of this tobacco store (that's what it was when I was a kid it's something else now) on the northwest corner of 63rd and Pulaski Rd in Chicago. One time when I was a kid I was on the CTA bus
The particle measures about 0.7 micrometres (thousandths of a millimetre) in diameter. "It is bigger than some bacteria," explained Prof Jean-Michel Claverie, from Aix-Marseille University, Marseille, France. "You don't need an electron micro
...researchers from Cornell University have demonstrated a working "temporal cloak" that is able to conceal a burst of light as if it had never occurred.
It's hard to comprehend the impact of the Black Death. The "Great Pestilence" is believed to have originated somewhere in Northern Asia in the 1330s before hitting Europe in 1347. It killed an estimated 75 million people worldwide
Dr Branney said: "It is one of the world's best-preserved accessible examples of such an awesome phenomenon, because the debris from such landslides mostly spreads far across the deep ocean floor, inaccessible for close study. "The beautifully-
Today, militaries from around the world — including Russia and China — are developing their own stealth arsenals. The American monopoly on near-invisible flight is being eroded.
Local government officials in Kemerovo said footprints and possibly even hair samples belonging to the yeti - or abominable snowman - had been found on a research trip.
Evidence for the kraken and its gruesome attacks comes from markings on the bones of the remains of nine 45-foot (14 meter) ichthyosaurs of the species Shonisaurus popularis, which lived during the Triassic, a period that lasted from 248 million to 2
All this means is that the big hunts were very much tribal affairs in which hundreds would gather to meet the migrating herds in order to knock down as much game as could be readily preserved over the next week by drying and smoking and converting in
While naturalists have known of slime molds for centuries, only now are scientists really starting to understand them. Lab experiments are revealing the complex choreography of signals in some species that allows 20,000 individuals to form a single s
Whoah! Check out this magical timelapse created from still-shots taken on-board the International Space Station on September 17, which are all available at The Gateway to Astronaut Photography of the Earth (ISS029, Roll E, Frames 5865 to 6210, for th
Take, for example, England’s Cannock Chase – a sprawling and dense mass of heath and woodland situated in the county of Staffordshire. For years, an absolute menagerie of unknown animals and out-of-place critters has been seen roaming the Chase. The
Serious scientists from Russia, the United States and other countries are gathering together during October 2011 for a conference followed by an expedition to hunt down the evasive Siberian Yeti. The expedition was announced in March 2011 and the tea
"I did a test site with a product early on and applied the product to a half-acre ... In 30 days I had two inches of dead ants covering the entire half-acre," Rasberry said. "It looked like the top of the dead ants was just total movement from all
sequences from many different genes, to examine how the different families of mammals are related to each other. This dataset, with all the sequences we generated, provides a large and reliable foundation - a springboard - for biologists to take the
He abandoned what would have been a fashionable project printing electronic circuits with nano-inks for one that seemed to have more in common with 1001 Nights than 21st-Century engineering.
The water in a comet called 103P/Hartley 2 is chemically very similar to water on Earth, suggesting that some of Earth's water comes from the same comet family, reports an international study led by Paul Hartogh at the Max-Planck-Institut fur Sonnen
The scenarios to be tested vary from a low-level event that would take out a handful of the transformers that control the grid that conceivably could be repaired within a matter of days, to a “worst case” scenario to simulate a total take-down of the
It's a bad day when 150 years of what everyone accepted as known must be tossed into the dust bin. That day may have arrived for cosmologists and their construct of the nature of the universe. At least Edmund Schluessel of Cardiff University thinks
director of the CPWF. "Yes, there is scarcity in certain areas, but our findings show that the problem overall is a failure to make efficient and fair use of the water available in these river basins. This is ultimately a political challenge, not a
Before the arrival of the Plantrose process, supercritical water had never successfully yielded sugar from biomass at significant scale. The process breaks down a wide range of non-food biomass in seconds, uses no significant consumables and produces
However, new research from scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) shows that at microscopic dimensions, the age-related loss of bone quality can be every bit as important as the loss o
. Thus the ability to control double bond positions would enable us to make new designer fatty acids that would be useful as industrial raw materials."
In this paper we report on the precision determination of the neutrino velocity, defined as the ratio of the precisely measured distance from CERN to OPERA to the time of flight of neutrinos travelling through the Earth’s crust. We used the high-st
Pennsylvania State University have developed a way to produce hydrogen that uses no grid electricity and is carbon neutral and could be used anyplace that there is wastewater near sea water.
"This provides additional support for the view that the mechanisms controlling the expression of yawning are involved in thermoregulatory physiology. Despite numerous theories posited in the past few decades, very little experimental research has be
But now it seems that researchers working in one of the world's largest physics laboratories, under a mountain in central Italy, have recorded particles traveling at a speed that is supposedly forbidden by Einstein's theory of special relativity.
