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
"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.
In any event in the case of Phobos with a mean radius of 11.1 we have an indicated shell thickness that is 2.5 to 3 km leaving a potential void having a radius of plausibly 8 km. This is huge of course but a spinning space habitat naturally provid
Varied impact craters, valleys, canyons and mountains among the highest in the Solar System - the 3D images and videos of the asteroid Vesta created byscientists at the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) reveal a
Dr. Denise L. Herzing intends to do something no person has ever done in the long history of the human race: establish a real dialogue with another species. Her goal is simple achieve a two-way conversation with dolphins, perhaps the smartest mammals
Developed in 2008 by the University of Washington, it is a fun-for-purpose video game in which gamers, divided into competing groups, compete to unfold chains of amino acids -- the building blocks of proteins -- using a set of online tools.
R returned evidence of living microorganisms. Initially discounted by NASA and most space scientists, the results of this milestone project have, nonetheless, been causing excitement and controversy ever since. In 1997, after 21 years of study of the
A cache of feathers preserved in amber, dating from around 70 to 85 million years ago, was just found in Canada, showing that border between winged dinosaurs and the earliest avians.
The National Maritime Museum's Royal Observatory in Greenwich England has announced the 2011 winners of its Astronomy Photographer of the Year contest, across categories from “Our Solar System” and “Deep Space” to “Best Newcomer” and “Young Astronomy
From there, the story echoes that of countless islands where the introduction of rats, cats, weasels and other predators upends the ecosystem. The island's nesting seabirds had no defenses against the predatory rats, which ate their eggs and their y
ASCE estimated the "costs to households and businesses" from transportation deficiencies in 2010 to be $130 billion. (pg. 3 of the report) ASCE estimated the cumulative losses to businesses will be $430 billion by 2020. (pg. 5) ASCE estimated
"With our approach to fabricating photonic crystals, there's a lot of potential to optimize electronic and optical properties simultaneously," said Erik Nelson, a former graduate student in Braun's lab who now is a postdoctoral researcher at Harv
Scientists have long known that birds, or avian dinosaurs, lived during the Mesozoic, the era when dinosaurs ruled the Earth. Although researchers have discovered numerous Mesozoic bird species, these were virtually all the size of crows or smaller.
The data "provide compelling evidence" that the oil component of the plume sampled in June 2010 essentially comprised benzene, toluene, ethybenzene, and total xylenes--together, called BTEX--at concentrations of about 70 micrograms per liter, the r
It all happened on the night of June 10,” she told KP. “I was sleeping, my daughter was sitting at the computer looking at the internet. She says that about 2.00 am she heard a sound in the yard. Some whining. “The dog which guards the farm scre
The results showed that King Tut belonged to a genetic profile group, known as haplogroup R1b1a2, to which more than 50 percent of all men in Western Europe belong, indicating that they share a common ancestor.
The two primary goals for a telescope are sensitivity and angular resolution. Interferometry among telescope arrays has become a standard technique in astronomy, allowing greater resolving power than would be available to a single telescope. In today
"There is no question in my mind it's muzzling," said Jeffrey Hutchings, a senior fisheries scientist at Halifax's Dalhousie University. "When the lead author of a paper in Science is not permitted to speak about her work, that is suppression
'Pterosaurs were the first flying animals - they appeared on Earth 50 million years before Archaeopteryx, the first bird - and they were good at what they did. But the amazing thing is that they didn't really begin to evolve until after the birds h
Canada's fabled East Coast fishery, which was feared to be gone forever, is showing "very positive" signs of recovery, according to scientists.
Scripps scientists Steve Cande and Dave Stegman have now discovered a new force that drives plate tectonics: Plumes of hot magma pushing up from Earth's deep interior. Their research is published in the July 7 issue of the journal Nature. Using a
They found the fossil buried just five inches below the K-T boundary, the geological layer that marks the transition from the Cretaceous period to the Tertiary period at the time of the mass extinction that took place 65 million years ago.
Scientists from British Antarctic Survey (BAS) have discovered previously unknown volcanoes in the ocean waters around the remote South Sandwich Islands. Using ship-borne sea-floor mapping technology during research cruises onboard the RRS James Clar
