IBM announced today it is investing $3 billion for R&D in two research programs to push the limits of chip technology and extend Moore’s law.

The research programs are aimed at “7 nanometer and beyond” silicon technology and developing alternative technologies for post-silicon-era chips using entirely different approaches, IBM says.

IBM will be investing especially in carbon nanoelectronics, silicon photonics, new memory technologies, and architectures that support quantum… read more

Transparent solar cells for windows that generate electricity

July 23, 2012

ucla_transparent_solar_cell

Researchers from UCLA and California NanoSystems Institute have developed a new transparent solar cell, giving windows in homes and other buildings the ability to generate electricity.

This new kind of polymer solar cell (PSC) produces energy by absorbing more near-infrared light but is less sensitive to visible light, making the cells nearly 70% transparent to the human eye. They use a near-infrared light-sensitive polymer and silver nanowire composite films as… read more

Samsung Electronics Co. said Sunday that it has successfully developed fifth-generation network (5G) core technology for the first time, allowing users to access faster data services expected to be available by 2020, Yonhap News Agency reports.

Under the new platform, users will be able to download and upload data at speeds of up to tens of gigabits per second (Gbps), compared to 75 megabits per second (Mbps)… read more

Wearable ‘neurocam’ records scenes when it detects user interest

February 10, 2014

Neuroware

Keio University scientists have developed a “neurocam” — a wearable camera system that detects emotions, based on an analysis of the user’s brainwaves.

The hardware is a combination of Neurosky’s Mind Wave Mobile and a customized brainwave sensor.

The algorithm is based on measures of “interest” and “like” developed by Professor Mitsukura and the neurowear team.

The users interests are quantified… read more

What zebrafish can teach us about healing brain damage

November 11, 2012

800px-Zebrafisch

The zebrafish regenerates its brain after injury, unlike mammals. Is there something we can learn about the process that might help with traumatic brain injury  and neurodegenerative disorders?

A research team at the Center for Regenerative Therapies Dresden (CRTD), Germany decided to investigate.

They found that that in zebrafish — in contrast to mammals — inflammation is a positive regulator of neuronal regeneration in the… read more

Biological transistor enables computing within living cells

Stanford University bioengineers have taken computing beyond mechanics and electronics into the living realm of biology by creating the “transcriptor” — a biological transistor made from DNA and RNA.

In electronics, a transistor controls the flow of electrons along a circuit. Similarly, a transcriptor controls the flow of a specific protein, RNA polymerase, as it travels along a strand of DNA.

“Transcriptors are the… read more

Fukushima plant spilling 300 tons of radioactive water every day into the sea since 2011

August 13, 2013

Mass contamination from major radiation exposure events, such as the meltdown at Japan’s Fukushima Daiichi nuclear power plant, require prompt treatment in the form of a pill, such as the treatment being developed at Berkeley Lab (credit: satellite image from Digital Globe)

Workers at the crippled Fukushima nuclear plant have told the Australian Broadcasting Company (ABC) that contaminated water has most likely been seeping into the sea since the disaster two-and-a-half years ago.

They do not have much faith in Tokyo Electric Power Company’s (TEPCO) ability to handle the situation and they claim another accident is inevitable.

Japan’s nuclear watchdog has described the leaks as a “state of… read more

Reprogramming your brain with transcranial magnetic stimulation

Weak repetitive transcranial magnetic stimulation (rTMS) applied to mice can shift abnormal neural connections to more normal locations in the brain, researchers from The University of Western Australia and the Université Pierre et Marie Curie in France have demonstrated.

The discovery has implications for treatment of nervous system disorders related to abnormal brain organization, such as depression, epilepsy, and tinnitus.

Panasonic develops highly efficient artificial photosynthesis system generating organic materials from carbon dioxide and water

August 1, 2012

panasonic_artificial_photosynthesis

Panasonic has developed an artificial photosynthesis system that converts carbon dioxide (CO2) to organic materials by illuminating with sunlight at a world’s top efficiency of 0.2%.

The efficiency is on a level comparable with real plants used for biomass energy. The key to the system is the application of a nitride semiconductor which makes the system simple and efficient.

This development will be a foundation… read more

World’s largest offshore wind farm generates first power

worlds-largest-offshore-windfarm

The first power has been produced at the London Array Offshore Wind Farm, DONG Energy, E.ON and Masdar have announced .

The 630MW scheme, located in the Thames Estuary, will be the world’s largest offshore wind farm, with construction on schedule to be finished by the end of the year.

The 175 turbines will produce enough power to supply over 470,000 UK homes with electricity.

Graphene antennas would enable terabit wireless downloads

March 6, 2013

Researchers at Georgia Tech have drawn up blueprints for a wireless antenna made from atom-thin sheets of carbon, or graphene, that could allow terabit-per-second transfer speeds at a range of about one meter, MIT Technology Review reports

This would make it possible to obtain 10 high-definition movies by waving your phone past another device for one second. At even shorter ranges, such as a few centimeters, data… read more

The Human Brain Project has officially begun

On Monday, October 7, 2013, scientists from the 135 partner institutions of the Human Brain Project — “the world’s most ambitious neuroscience project”— met at EPFL (Ecole polytechnique fédérale de Lausanne), the coordinating institution, in Switzerland.

Over the course of the coming week, neuroscientists, doctors, computer scientists, and roboticists will fine-tune the project’s details.

Six months after its selection by the EU as one… read more

Self-driving vehicles: benefits to society, policy challenges for lawmakers

January 6, 2014

Imagined autonomous vehicle

Self-driving vehicles offer the promise of significant benefits to society, but raise several policy challenges, including the need to update insurance liability regulations and privacy concerns such as who will control the data generated by this technology, according to a new RAND Corporation study.

“Our research finds that the social benefits of autonomous vehicles — including decreased crashes, increased mobility and increases… read more

The notion that 3D printing will on any reasonable time scale become a “mature” technology that can reproduce all the goods on which we rely is to engage in a complete denial of the complexities of modern manufacturing, unless you’d like everything made out of plastic, says Technology Review | Mim’s Bits blog.
