Cutting-edge technology was billed as a way to decipher where exactly the morass of nuclear fuel might sit at the bottom of reactors in the Japanese power plant that went into multiple meltdowns four years ago. But the technology went wrong today during a simple demonstration for reporters. It’s a sobering reminder of the enormous challenges that lie ahead for the decommissioning of Fukushima Dai-ichi.
Imaging tests like mammograms or CT scans can detect tumors, but figuring out whether a growth...
This afternoon, Scott Kelly and Mikhail Kornienko will launch to the ISS, beginning a one-year...
One infrared scan can give pathologists a window into the structures and molecules inside tissues and cells, enabling fast and broad diagnostic assessments, thanks to an imaging technique. Using a combination of advanced microscope imaging and computer analysis, the new technique can give pathologists and researchers precise information without using chemical stains or dyes.
Researchers have created a transparent nanoscale capillary out of graphene to investigate the atomic structure of water trapped inside. They used high magnification electron microscopy that allowed them to see individual water molecules. To their surprise, the scientists found small square crystals of ice at room temperature, provided the graphene capillaries were narrow enough, allowing no more than three atomic layers of water.
A plastic used in filters and tubing has an unusual trait: it can produce electricity when pulled or pressed. This ability has been used in small ways, but now researchers are coaxing fibers of the material to make even more electricity for a wider range of applications from green energy to "artificial muscles."
Physicists have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results represent the largest number of particles that have ever been mutually entangled experimentally.
Effective lab-based tests are required to eliminate the need for animal testing in assessing the toxicological effects of inhaled chemicals and safety of medicines. A 3-D model of human respiratory tissue has been shown to be an effective platform for measuring the impact of chemicals, like those found in cigarette smoke, or other aerosols, on the lung.
Scientific literature traces manhole explosions back nearly a century, but a series of such incidents in Indianapolis has authorities looking for a quick solution. A combination of power system design, winter road salt, older electrical cable insulation and basic chemistry have triggered underground explosions in older downtowns, launching 350-pound manhole covers high in the air.
Researchers have developed a county-by-county map of the U. S. that tells a story of land cover and development across the nation, and could provide a framework for future development. They integrated satellite data with census population data and produced a map that depicts— in vivid shades of red and green— how each county's developed land compares to that of counties with similar populations.
Laboratory Equipment’s scientist of the week is Diane Favro from UCLA. Favro and a team recreated Augustan Rome algorithmically using a technique known as procedural modeling. According to legend, the founder of the Roman Empire, Augustus, boasted, “I found Rome a city of bricks and left it a city of marble.” Favro wanted to know if he telling the truth or making an empty claim.
“Create a password” is a prompt familiar to anyone who has tried to buy a book from Amazon or register for a Google account. Equally familiar is that red / yellow / green bar that rates the new password’s strength. But when those meters give the go-ahead to passwords like Password1+, their effectiveness is called into question.
A pocket-sized device that can rapidly determine the sequence of an organism's DNA has shown its potential in disease detection. In the first analysis of its kind, researchers were able to use the device to accurately identify a range of closely related bacteria and viruses within six hours, demonstrating the potential for this technology to be used as a mobile diagnostic clinic during outbreaks.
New findings from an international team of archeological researchers highlight the complexity of geopolitics in Aztec era Mesoamerica and illustrate how the relationships among ancient states extended beyond warfare and diplomacy to issues concerning trade and the flow of goods.
Officials say a minor glitch will delay the restart of Europe's multi-billion dollar Large Hadron Collider either a couple of days or more than a month. A small metallic piece near a magnet has to be removed before the machine fires its circulating beam.
Improving the efficiency of the current wastewater cleaning process, using membrane filtration and oxidation, can remove more than 95 percent of contaminants, such as drug residues and pesticides, from water. The results show that these technologies remove up to 99 percent of contaminants and nutrients.
An energy company is joining forces with a tech startup to harness computing power to heat homes in the Netherlands. A Dutch-based energy company with more than 2 million customers said today it is installing "e-Radiators" in five homes in a trial to see if their warmth could be a commercially viable alternative for traditional radiators.
An experiment has, for the first time, demonstrated Albert Einstein's original conception of "spooky action at a distance" using a single particle. Researchers used homodyne measurements to show what Einstein did not believe to be real, namely the non-local collapse of a particle's wave function.
New observations made with telescopes reveal that the star that European astronomers saw appear in the sky in 1670 was not a nova, but a much rarer, violent breed of stellar collision. It was spectacular enough to be easily seen with the naked eye during its first outburst, but the traces it left were so faint that very careful analysis using submillimeter telescopes was needed before the mystery could be explained.
Three of the nation’s largest philanthropies, the HHMI, the Bill & Melinda Gates Foundation and the Simons Foundation are announcing a new partnership to provide much needed research support to outstanding early career scientists in the U.S. Through the new Faculty Scholars Program, the philanthropies will invest a total of $148 million in research support over the program’s first five years.
Francisco Rangel has won FEI’s 2014 Image Contest grand prize for his “Expanded Vermiculite.” Vermiculite is a hydrated magnesium-aluminum-iron-silicate. It is a versatile mineral that is clean to handle, odorless and mold-resistant.
Poop could be a goldmine— literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now, researchers are looking at identifying the metals that are getting flushed and how they can be recovered. This could decrease the need for mining and reduce the unwanted release of metals into the environment.
If every new car made in the U.S. had a built-in blood alcohol level tester that prevented impaired drivers from driving the vehicle, how many lives could be saved, injuries prevented and injury-related dollars left unspent? According to researchers, estimates of injury prevention and cost savings are significant.
A device resembling a plastic honeycomb yet infinitely smaller than a bee's stinger can steer light beams around tighter curves than ever before possible, while keeping the integrity and intensity of the beam intact. The work introduces a more effective way to transmit data rapidly on electronic circuit boards by using light.
A new study has shown how to sharpen nanoscale microscopy (nanoscopy) even more by better locating the exact position of the light source.
An Indiana Univ. cognitive scientist and collaborators have found that posture is critical in the early stages of acquiring new knowledge. The study offers a new approach to studying the way "objects of cognition," such as words or memories of physical objects, are tied to the position of the body.
Researchers developed a system for obtaining clean hydrogen that can be used as fuel.
Researchers have helped untangle a long-standing mystery of astrophysics: why iron is found spattered throughout Earth’s mantle, the roughly 2,000-mile thick region between Earth’s core and its crust.
