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

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

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

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

Mapping the ‘fountain of youth’

Tibolium_castaneum_TERT_structure

University of Copenhagen researchers and an international team have for the first time mapped telomerase, an enzyme with a rejuvenating effect on cell aging.

This is one of the results of a major research project involving more than 1,000 researchers worldwide, four years of hard work, DKK 55 million from the EU, and blood samples from more than 200,000 people.

It is the largest collaboration project… read more

The Human Brain Project has officially begun

Scientists from the 135 partner institutions meeting in Switzerland this week
October 7, 2013

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

Reflected hidden faces in photographs revealed in pupil

The pupil* of the eye in a photograph of a face can be mined for hidden information, such as reflected faces of the photographer and bystanders, according to research led by Dr. Rob Jenkins, of the Department of Psychology at the University of York and published in PLOS ONE (open access).

The researchers say that in crimes in which the victims are photographed, such as hostage… read more

Researchers at the U.S. Department of Energy’s Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies.

Magnetic switching is used to encode information in hard drives, magnetic random access memory and other computing devices. The discovery, reported in the April 4 issue… read more

A Terminator-style contact-lens display

(Credit: University of Washington/

Bringing us a step closer to a Terminator-style augmented-reality display, University of Washington engineers have constructed an experimental contact lens with a single-pixel embedded light-emitting diode (LED) and tested it in a rabbit.

The LED lights up when it receives energy from a remote radio frequency transmission, picked up by an antenna around the edge and collected via a silicon power harvesting and radio integrated circuit.

But the… read more

A tiny computer attracts a million tinkerers

January 31, 2013

The Raspberry Pi Model B is a credit–card sized computer board that plugs into a TV. It’s a miniature ARM–based PC that can perform many of the functions of a large desktop PC such as spreadsheets, word–processers and games. It also plays High–Definition videos. (Credit: Raspberry Pi)

Almost one million $35 Raspberry Pi computers have shipped since last February, capturing the imaginations of educators, hobbyists and tinkerers around the world, The New York Times reports.

The Raspberry Pi — about 3 inches by 2 inches and less than an inch high — was intended to replace the expensive computers in school science labs. For less than the price of a new keyboard, a… read more
