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...

Using Nanotubes in Computer Chips : A new technique for growing carbon nanotubes should be easier to integrate with existing semiconductor manufacturing processes

Location: Cambridge, United States

Source: "Low Temperature Synthesis of Vertically Aligned Carbon Nanotubes with Electrical Contact to Metallic Substrates Enabled by Thermal Decomposition of the Carbon Feedstock," Gilbert Nessim, Carl V. Thompson et al, Nano...

Performance Parameters in GPRS Based Traffic with Data and Voice Integrated Transmission

Location: Dhaka, Bangladesh

Abstract :

 

General Packet Radio Service (GPRS) is a new bearer service for Global System for Mobile (GSM) that...

Formation of Ozone and Growth of Aerosols in Young Smoke Plumes from Biomass Burning

Location: Cambridge, United States

The combustion of biomass is a major source of atmospheric trace gases and aerosols. Regional- and global-scale models of atmospheric chemistry and climate take estimates for these emissions and arbitrarily "mix" them into grid boxes...

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,

Illuminating molecules from within : Calculations show that with new short pulse x-ray light sources, it should be possible to use photoelectron emission to make movies of changes in molecular structure.

Location: Berkeley, United States

Much of our knowledge about molecular structure and reactivity is based on interpreting how molecules interact with light. In particular, time-resolved pump-probe studies where a first “pump” laser pulse initiates a dynamical event,...

Robots swim with the fishes : New robots mimic fish's swimming, could be used in underwater exploration

Location: Cambridge, United States

Borrowing from Mother Nature, a team of MIT researchers has built a school of swimming robo-fish that slip through the water just as gracefully as the real thing, if not quite as fast.

Mechanical engineers Kamal Youcef-Toumi and Pablo...

Pushing the envelope of general relativity

Location: Tokyo, Japan

Einstein introduced general relativity in the early 20th century, and since then it has been proven to be an accurate description of gravity beyond the regime of validity of Newtonian gravitation. Since then, people have been asking...

Confinement of Electrons to Diamond Isotopes : Super lattice structure realized using only carbon

Location: Tsukuba, Japan

Among all available materials, diamond has the optimal characteristics with respect to hardness, thermal conductivity, light transmission wavelength range, and chemical stability. Furthermore, as a semiconducting material, diamond shows...

A better way to pinpoint underground oil reserves : CEE mapping technology could make extraction more efficient

Location: Cambridge, United States

An accurate map of a large underground oil reservoir that can guide engineers' efforts to coax the oil from the vast rocky subsurface into wells where it can be pumped out for storage or transport.

Researchers in MIT's Department of...

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...

Stuck in the middle : research explains how thin layers of tiny organisms form at sea; work could help predict harmful algal blooms like red tide

Location: Cambridge, United States

Not far beneath the ocean's surface, tiny phytoplankton swimming upward in a daily commute toward morning light sometimes encounter the watery equivalent of Rod Serling's Twilight Zone: a sharp variation in marine currents that traps...

More power from bumps in the road : energy-harvesting shock absorbers

Location: Cambridge, United States

A team of MIT undergraduate students has invented a shock absorber that harnesses energy from small bumps in the road, generating electricity while it smoothes the ride more effectively than conventional shocks. The students hope to...

New rocket aims for cheaper nudges in space : Plasma thruster is small, runs on inexpensive gases

Location: Cambridge, United States

Satellites orbiting the Earth must occasionally be nudged to stay on the correct path. MIT scientists are developing a new rocket that could make this and other spacecraft maneuvers much less costly, a consideration of growing importance as...

Good vibrations : Devices aid the deaf by translating sound waves to vibrations

Location: Cambridge, United States

Lip reading is a critical means of communication for many deaf people, but it has a drawback: Certain consonants (for example, p and b) can be nearly impossible to distinguish by sight alone.

Tactile devices, which translate sound...

Manufacturing inefficiency : Study sees 'alarming' use of energy, materials in newer manufacturing processes

Location: Cambridge, United States

Modern manufacturing methods are spectacularly inefficient in their use of energy and materials, according to a detailed MIT analysis of the energy use of 20 major manufacturing processes.

Overall, new manufacturing systems are...

New material could lead to faster chips : Graphene may solve communications speed limit

Location: Cambridge, United States

New research findings at MIT could lead to microchips that operate at much higher speeds than is possible with today's standard silicon chips, leading to cell phones and other communications systems that can transmit data much faster.

...

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,...

New virus-built battery could power cars, electronic devices

Location: Cambridge, United States

For the first time, MIT researchers have shown they can genetically engineer viruses to build both the positively and negatively charged ends of a lithium-ion battery.

The new virus-produced batteries have the same energy capacity and...
