EPFL’s Institute of Microengineering has reached a remarkable 10.7% efficiency for a single-junction microcrystalline silicon solar cell, surpassing the previous world record of 10.1% held by the Japanese company Kaneka Corporation since 1998.

The efficiency increase was also achieved with with only 1.8 microns of photovoltaic active material — 100 times less material than with standard wafer-based crystalline silicon PV technology.

Newspapers have continued to churn out the same content while watching their advertisers steadily flee for sites like Craigslist, Yahoo, the Huffington Post/AOL, Facebook, and Google, says writer Will Oremus in Slate Future Tense.  

The chart above, from Statista’s Felix Richter, plots Google’s digital advertising revenue against the print advertising revenue of all U.S.… read more

Technology mimics the brushstrokes of masters

October 24, 2013

New technology in 3-D printing has reached the art world. The race is on to produce high-quality 3-D reproductions of masterpieces by such artists as Rembrandt and Vincent van Gogh, The New York Times reports.

This year the Van Gogh Museum in Amsterdam teamed up with Fujifilm in Japan to produce the first fully color-corrected three-dimensional copies of some of van… read more

‘Neural dust’ brain implants could revolutionize brain-machine interfaces and allow large-scale data recording

July 17, 2013

Neural dust

In a potential neuroscience breakthrough, University of California Berkeley scientists have proposed a system that allows for thousands of ultra-tiny “neural dust” chips to be inserted into the brain to monitor neural signals at high resolution and communicate data highly efficiently via ultrasound.

The neural dust design promises to overcome a serious limitation of current invasive brain-machine interfaces (BMI): the lack of an implantable neural interface system that remains… read more

Queen Mary University of London researchers have developed a Google Play app called Phoney based on a mind-reading card trick, part of a research exploration into what can be achieved when human intelligence is replaced or assisted by machine intelligence.

The app arranges a deck of playing cards in such a way that a specific card picked by an audience member can beread more

John Moravec of Education Futures interviewed mathematician and science-fiction writer Vernor Vinge, noted for his foundational 1993 essay, “The Coming Technological Singularity.

“I’m still where I was in my 1993 essay that I gave at a NASA meeting, and that is that I define the Technological Singularity as being our developing, through technology, superhuman intelligence — or becoming, ourselves, superhuman intelligent through technology,” said Vinge.

Scott Summit created a 3D model of his ideal guitar and sent the computer design to 3D Systems, which used its massive 3D printers to transform the graphic model into an actual acoustic instrument that Summit can play, Bloomberg Businessweek reports.

As far as anyone seems to know, this is the first 3D-printed guitar on the planet, and it raises all kinds musical possibilities. “It’s rich and full and… read more

A strange lonely planet found without a star

An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago — -a newborn in planet lifetimes.

It was identified from its faint and unique heat signature by the … read more

On May 14, 2014, astronomers at Parkes Radio Telescope led by Emily Petroff at Swinburne University of Technology observed live an extremely short, sharp “fast radio burst” for 2.8 milliseconds at a microwave frequency of 1.4 GHz from an unknown source at an estimated distance of up to 5.5 billion light years from Earth. 24 seconds later, an email alert went out to astronomers at… read more

Real-world stereotypes continue to exist in virtual worlds

Stereotypes related to gender and appearance that burden women in the real world could follow them into virtual ones, according to Penn State researchers.

In a study of how people interacted with avatars in an online game, women received less help from fellow players than men when they operated an unattractive avatar and when they used a male avatar, said T. Franklin Waddell, a doctoral candidate in massread more

A new battery that’s cheap, clean, rechargeable, and organic

Could pave the way for renewable energy sources to make up a greater share of a country's energy generation by economically storing energy at night

Scientists at USC have developed a water-based organic battery that is long-lasting and built from cheap, eco-friendly components (no metals or toxic materials).

The new battery is intended for use in power plants, where it could make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as needed.

“The batteries last for about 5,000 recharge cycles, giving them an estimated… read more
