Technology Fails to See Inside Fukushima

March 27, 2015 3:00 pm | by Associated Press, Yuri Kageyama | News | Comments

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.

Tissue Samples Can Be Painted with Light

March 27, 2015 7:00 am | by Univ. of Illinois | News | Comments

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.

Graphene Makes Square Water

March 27, 2015 7:00 am | by The Univ. of Manchester | News | Comments

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.

Plastic Has Energy, Artificial Muscle Applications

March 26, 2015 3:00 pm | by ACS | News | Comments

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."

Recent Manhole Explosions Caused by Winter, Age and Chemistry

March 26, 2015 7:00 am | by Associated Press, Seth Borenstein | Videos | Comments

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.

County-by-county Map Shows U.S. Development

March 26, 2015 7:00 am | by SUNY College of Environmental Science and Forestry | News | Comments

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.

Q&A: Diane Favro and Rebuilding Ancient Rome

March 26, 2015 7:00 am | by Lily Barback, Associate Editor | News | Comments

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.

Password Strength Meters Aren't Uniform

March 26, 2015 7:00 am | by Concordia Univ. | News | Comments

“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.

Tiny DNA Sequencer May Aid Disease Surveillance

March 26, 2015 7:00 am | by BioMed Central | News | Comments

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.

Archeologists Uncover Aztec Empire's Complex Geopolitics

March 25, 2015 3:00 pm | by North Carolina State Univ. | News | Comments

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.

'Minor Glitch' is a Big Setback for Large Hadron Collider

March 25, 2015 7:00 am | by Associated Press | News | Comments

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.

Cleaning Could Remove 95% of Contaminates from Wastewater

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.

Experiment Proves Einstein's 'Spooky Action at a Distance’

March 24, 2015 3:00 pm | by Griffith Univ. | News | Comments

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.

Telescopes Explain Mysterious 17th Century Explosion

March 24, 2015 7:00 am | by ESO | News | Comments

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.

We Flush Valuable Metals, Critical Elements

March 23, 2015 3:00 pm | by ACS | News | Comments

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.
