Semiconductor Tech Key to ‘Google Maps’ for Human Body

March 31, 2015 7:00 am | by Univ. of New South Wales | Videos | Comments

Previously top-secret technology that zooms through the human body down to the level of a single cell could be a game-changer for medicine. The imaging technology, developed by high-tech German optical and industrial measurement manufacturer Zeiss, was originally developed to scan silicon wafers for defects.

Plants Enable Extremely Accurate Temperature Sensor

March 31, 2015 7:00 am | by ETH Zurich | News | Comments

In order to develop an extremely sensitive temperature sensor, researchers took a close look at temperature-sensitive plants. However, they did not mimic the properties of the plants— instead, they developed a hybrid material that contains, in addition to synthetic components, the plant cells themselves.  

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.

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.

Method Yields Quality-control Tool for Nanocomposites

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

Layered nanocomposites containing tiny structures mixed into a polymer matrix are gaining commercial use, but their complex nature can hide defects that affect performance. Now, researchers have developed a system capable of detecting such defects using a "Kelvin probe" scanning method with an atomic force microscope.

March 26, 2015 3:00 pm | by MIT, Jennifer Chu | News | Comments

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.

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.

'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.

Computers to Heat Homes

March 24, 2015 3:00 pm | by Associated Press | News | Comments

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.

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.

Earth Has Hidden Layer

March 23, 2015 3:00 pm | by Univ. of Utah | News | Comments

By crushing minerals between diamonds, a study has suggested the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: why slabs of Earth's sinking tectonic plates sometimes stall and thicken 930 miles underground.

Biodegradable Plastic Doesn't

March 20, 2015 3:00 pm | by Michigan State Univ. | News | Comments

Recycling plastic works; additives to biodegrade plastic do not. A new study has shown that several additives that claim to break down polyethylene and polyethylene terephthalate simply don’t work in common disposal situations such as landfills or composting.
