Can superconducting rings provide clues to the early development of the universe?

Location: Nepoli, France

Watching a metal transform into a superconductor, it may not be obvious that this transition provides access to some of the same physics that governed the cooling of the universe following the Big Bang. Yet at the root of both of these...

Shifting entropy elsewhere : New methods for lowering the entropy of ultracold gases may allow observation of more subtle quantum materials.

Location: Berkeley, United States

Ultracold atoms are still too hot. This may seem a ridiculous claim—after all, the low-temperature exploits of the purveyors of quantum gases are notorious. Laser cooling can flash-freeze atoms to temperatures in the micro- and nanokelvin...

NanoPen: Dynamic, Low-Power, and Light-Actuated Patterning of Nanoparticles

Location: California, United States

Abstract:

The ability to pattern nanostructures has important applications in medical diagnosis,(1, 2) sensing,

Enlisting microbes to solve global problems : Researchers harness bacteria to produce energy, clean up environment

Location: Cambridge, United States

In the search for answers to the planet's biggest challenges, some MIT researchers are turning to its tiniest organisms: bacteria.

The idea of exploiting microbial products is not new: Humans have long enlisted bacteria and yeast to...

Knowing when to fold : Engineers use 'nano-origami' to build tiny electronic devices

Location: Cambridge, United States

Folding paper into shapes such as a crane or a butterfly is challenging enough for most people. Now imagine trying to fold something that's about a hundred times thinner than a human hair and then putting it to use as an electronic device....

'Nanostitching' could lead to much stronger airplane skins, more

Location: Cambridge, United States

MIT engineers are using carbon nanotubes only billionths of a meter thick to stitch together aerospace materials in work that could make airplane skins and other products some 10 times stronger at a nominal increase in cost.

Moreover,...

Re-engineered battery material could lead to rapid recharging of many devices : Beltway for electrical energy solves long-standing problem

Location: Cambridge, United States

MIT engineers have created a kind of beltway that allows for the rapid transit of electrical energy through a well-known battery material, an advance that could usher in smaller, lighter batteries -- for cell phones and other devices -- that...

Nanospheres on a Silver Platter

Location: IL , United States

Illinois researchers in the Department of Materials Science and Engineering--post-doctoral fellow LinLin Wang and

Genesis of fish shoals: Observations of herring apply to other animals; could impact conservation

Location: Cambridge, United States

For the first time, MIT engineers and colleagues have observed the initiation of a mass gathering and subsequent migration of hundreds of millions of animals -- in this case, fish.

The work, conducted using a novel imaging technique,...

Robotic therapy holds promise for cerebral palsy

Location: Cambridge, United States

Devices can help children with brain injuries learn to grasp and manipulate objects

Over the past few years, MIT engineers have successfully tested robotic devices to help stroke patients learn to control their arms and...

Solar Cells with Self-assembled Nanowires

Location: Seattle, United States

A single hour of sunlight contains enough energy to meet global energy consumption for an entire year. With demand for energy on the rise and environmental pollution an increasing concern, scientists are exploring new ways to harness the sun's...

Propelling Underwater Vehicles Using Vortex Ring Generation

Location: California, United States

Abstract : As robots designed to operate underwater become more common, it is useful to look at ways to make them more efficient. Autonomous Underwater Vehicles (AUVs) carry their power source with them, so improving the efficiency of the...

Cutting CO2 emissions from existing coal plants

Location: Cambridge, United States

Professor Ernest Moniz, director of the MIT Energy Initiative (MITEI) unveiled a report on reducing carbon dioxide emissions from existing coal plants. The report is based on the findings of a major MIT symposium on retrofitting coal-fired power...

Scientists Work To Plug Microorganisms Into The Energy Grid

Location: Oak Ridge, United States

The answer to the looming fuel crisis in the 21st century may be found by thinking small, microscopic in fact. Microscopic organisms from bacteria and cyanobacteria, to fungi and microalgae, are biological factories that are proving to be...

Unique Survey Of Ocean Climate May Improve Climate Predictions

Location: Nansen, Norway

A research team from the Nansen Environmental and Remote Sensing Center, and the Bjerknes Centre for Climate Research, both in Bergen, Norway, has studied observed anomalies in ocean climate, and identified the anomalies’ progression...

New tool transforms the Internet into seismologists

Location: Paris, France

A few seconds after the earthquake that devastated L'Aquila, in Abruzzo, a group of seismologists, south of Paris, already knew that a quake of earth had to produce. Their instruments? The Web. Seismologists? Witnesses themselves. To...

New molecular force probe stretches molecules, atom by atom

Location: Illinois, United States

Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed.
...

New Listening Device Should Help Find Trapped Miners

Location: University of Utah, United States

University of Utah scientists devised a new way to find miners trapped by cave-ins. The method involves installing iron plates and sledgehammers at regular intervals inside mines, and sensitive listening devices on the ground...

Intruder alert: 'Smart Dew' will find you!

Location: Tel Aviv, Israel

A remarkable new invention from Tel Aviv University — a network of tiny sensors as small as dewdrops called "Smart Dew" — will foil even the most determined intruder. Scattered outdoors on rocks, fence posts and...

Hydrogen: a new electrolysis process would decrease production costs

Location: Pennsylvania, United States

Hydrogen is an attractive alternative to address the depletion of fossil fuels. A large-scale exploitation of this form of energy requires, however, to resolve a number of technical problems associated with the production, transport and...
