How to inkjet-print circuits at fraction of time and cost

November 8, 2013

A single-sided wiring pattern for an Arduino micro controller was printed on a transparent sheet of coated PET film.

A novel method to rapidly and cheaply 3D-print electrical circuits has been developed by researchers from Georgia Tech, the University of Tokyo, and Microsoft Research.

For about $300 in equipment costs, anyone can produce working electrical circuits in the 60 seconds it takes to print them using commodity inkjet printers and off-the-shelf materials.

Instant inkjet circuits

The technique, called instant inkjet circuits, allows for printing arbitrary-shaped conductors… read more

A five-year, multidisciplinary collaborative research effort based at Cornell has resulted in the world’s best material for tunable capacitors — broadly called a tunable dielectric, a special insulator whose ability to store electrical charge changes when a voltage is applied.

“This is a radically different material compared to what people have been using for decades,” said Darrell Schlom, the Herbert Fisk Johnson Professor of Industrial Chemistry at Cornell, who… read more

Just a few years of early musical training benefits the brain later in life

November 7, 2013

music changes

Older adults who took music lessons as children but haven’t actively played an instrument in decades have a faster brain response to a speech sound than individuals who never played an instrument, according to a  new study by Northwestern University researchers.

They found that the more years study participants spent playing instruments as youth, the faster their brains responded to a speech sound.

As people grow older, they… read more

An analog synaptic transistor with spike-timing-dependent plasticity learning

First of its kind brain-inspired device looks toward highly efficient and fast parallel computing
November 7, 2013

Synaptic-transistor-web

Materials scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have created a new type of neuromorphic transistor that mimics the behavior of a synapse. The novel device simultaneously modulates the flow of information in a circuit and physically adapts to changing signals.

Exploiting unusual properties in modern materials, the synaptic transistor could mark the beginning of a new kind of artificial intelligence:… read more

Southeast Asia’s first nanomedicine research institute gets $60 million funding

November 6, 2013

NTU is the world's largest engineering university

Nanyang Technological University (NTU) is establishing the new $60 million Nanomedicine Institute@NTU to focus on applications of nanotechnology for diabetes, cardiovascular, ophthalmology, and skin therapeutics.

Set to be Southeast Asia’s first research institute in nanomedicine, the new institute will be headed by Professor Subbu Venkatraman, Chair of NTU’s School of Materials Science and Engineering, with Professor Chad Mirkin from Northwestern University as the chairman of its advisory committee.… read more

Findings may lead to new tissue cryopreservation methods for grafts and organ transplantations

November 6, 2013

Researchers have gained new information about the processes that promote freezing of cells within tissues, which could ultimately lead to novel approaches for preventing tissue injury during cryopreservation, they report in the Nov. 5 issue of the Biophysical Journal (open access), a Cell Press publication.

Developing an efficient way to freeze and store living tissues could transform many aspects of medical care and research, but… read more

Tens of billions of potentially habitable, Earth-size planets in our galaxy, say astronomers

The nearest such planet may be within 12 light-years

One in five stars in our galaxy like the Sun have planets about the size of Earth and a surface temperature conducive to life, astronomers at UC Berkeley and University of Hawaii, Manoa now estimate.

The estimate was based on a statistical analysis of all the Kepler observations of NASA’s Kepler space telescope of the 200 billion stars in our galaxy.

Given that about… read more

Black holes found in globular star clusters, upsetting 40 years of theory

Astrophysicists have discovered another example of a black hole in a globular star cluster for a total of three, upsetting 40 years of theories against their possible existence.

Tom Maccarone, a Texas Tech University associate professor of physics, said globular star clusters are large groupings of stars thought to contain some of the oldest stars in the universe and could have… read more

Metamaterial might improve TMS depression treatment

November 5, 2013

TMS headpiece

A brain stimulation technique that is used to treat tough cases of depression could be considerably improved with a new headpiece designed by University of Michigan engineers.

Computer simulations showed that the headpiece — a square array of 64 circular metallic coils — could one day help researchers and doctors hit finer targets in the brain that are twice as deep as they can reach… read more

How nanotechnology can advance regenerative medicine

Nanotechnology may provide new strategies for regenerative medicine, including better tools to improve or restore damaged tissues, according to a review paper that summarizes the current state of knowledge on nanotechnology with application to stem cell biology.

Researchers have found that the adhesion, growth, and differentiation of stem cells are likely controlled by their surrounding microenvironment, which contains both chemical and physical cues. These cues include the… read more

‘No morsel too minuscule for NSA,’ says New York Times

MIT chemists have built a sensor using carbon nanotubes that can monitor nitric oxide (NO) in living animals for more than a year.

Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed.

“Nitric oxide has contradictory roles in cancer progression, and we need new… read more
