Graphene micro-supercapacitors to replace batteries for microelectonics devices

Will power biomedical implants, active RFID tags, embedded micro-sensors, and flexible electronics
February 27, 2013

Micro-supercapacitor

UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate miniature graphene-based supercapacitors — devices that can charge and discharge a hundred to a thousand times faster than standard batteries.

These micro-supercapacitors, made from a one-atom–thick layer of carbon, can be easily manufactured and readily integrated into small devices, such as next-generation pacemakers.

The new cost-effective fabrication method holds promise for the… read more

Drug laws are ‘worst case of scientific censorship in modern times’

June 17, 2013

brain_psilocybin

Outlawing psychoactive drugs amounts to the worst case of scientific censorship in modern times, leading scientists have argued.

UN conventions on drugs in the 1960s and 1970s have not only compounded the harms of drugs but also produced the worst censorship of research for over 300 years. This has set back research in key areas such as consciousness by decades and effectively stopped the investigation of promising… read more

Scientists speculate on top-secret Mars Rover discovery

NASA’s Curiosity rover’s Sample Analysis at Mars (SAM) instrument has likely relayed some provocative findings, Space.com reports.

John Grotzinger, lead mission investigator for the Curiosity rover, set the rumors in motion during an interview with NPR last week, saying, “We’re getting data from SAM … this data is gonna be one for the history books. It’s looking really good.”

Most scientists contacted… read more

Domestic drones and their unique dangers

March 31, 2013

AR Drone 2.0

The use of drones by domestic U.S. law enforcement agencies is growing rapidly, both in terms of numbers and types of usage, blogger Glenn Greenwald writes in The Guardian.

A short summary of Greenwald’s comprehensive article:

  • The belief that weaponized drones won’t be used on U.S. soil is patently irrational. Police departments are already speaking openly about how their drones “could be equipped to carry

A bucket-full of this material can absorb all the oxygen in a room

The stored oxygen can be easily released again whenever and wherever needed

A new crystalline material absorbs 160 times more oxygen than in the air around you — only a spoonful bucket-full (10 liters) of it is enough to suck up all the oxygen in a room, according to its developer, Professor Christine McKenzie in the Department of Physics, Chemistry and Pharmacy at the University of Southern Denmark.

A few grains of this material might absorb enough oxygen from the… read more

Replacing a defective gene with a correct sequence to treat genetic disorders

April 10, 2014

NewsImage-GeneRepair

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

The findings, described in the March 30 issue of Nature Biotechnology, offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with… read more

Tesla Autopilot predicts collision ahead seconds before it happens

Tesla autopilot predicts

Hans Noordsij, a Dutch Tesla driver, uploaded a Dec. 27 dashcam video that dramatically shows the new radar processing capacity of Tesla’s Autopilot and resulting auto-breaking, DarkVision Hardware reports. The system’s radar saw ahead of the car in front and tracked two cars ahead on the road. Note the audible warning a second or so before the accident.

Drones are no longer the sole domain of the military, and just as with many new technologies, they can easily fall into the wrong hands,  global security advisor, writer and consultant  reports in Time.

Criminal organizations are early adopters of technology, and some have already used UAVs and other forms of robotics to violate the law… read more

Supersapiens, the Rise of the Mind

In the new film Supersapiens, writer-director Markus Mooslechner raises a core question: As artificial intelligence rapidly blurs the boundaries between man and machine, are we witnessing the rise of a new human species?

“Humanity is facing a turning point — the next evolution of the human mind,” notes Mooslechner. “Will this evolution be a hybrid of man and machine, where artificial intelligence forces the emergence of a… read more

Musk, others commit $1 billion to non-profit AI research company to ‘benefit humanity’

Open-sourcing AI development to prevent an AI superpower takeover
December 11, 2015

OpenAI ft

Elon Musk and associates announced OpenAI, a non-profit AI research company, on Friday (Dec. 11), committing $1 billion toward their goal to “advance digital intelligence in the way that is most likely to benefit humanity as a whole, unconstrained by a need to generate financial return.”

The funding comes from a group of tech leaders including Musk, Reid Hoffman, Peter Thiel, and Amazon Web Services, but the… read more

Amazingly realistic digital screen characters are finally here

Zoe

Meet Zoe: a digital talking head. She can express a range of human emotions on demand with “unprecedented realism” and could herald a new era of human-computer interaction, according to researchers at Toshiba’s Cambridge Research Lab and the University of Cambridge’s Department of Engineering, who created her.

Zoe, or her offspring, could be used as a visible version of Siri, as… read more

Research debunks the ‘IQ myth’

After conducting the largest online intelligence study on record, with more than 100,000 participants, a Canadian Western University-led research team has concluded that the notion of measuring one’s intelligence quotient or IQ by a singular, standardized test is highly misleading.

Utilizing an online study open to anyone, anywhere in the world, the researchers asked respondents to complete 12 cognitive tests tapping memory, reasoning, attention and… read more

Planetary scientists have calculated that there are hundreds of billions of Earth-like planets in our galaxy which might support life.

The new research, led by PhD student Tim Bovaird and Associate Professor Charley Lineweaver from The Australian National University (ANU), made the finding by applying a 200 year old idea called the Titius-Bode relation — used to predict the existence of… read more

Robot learns to use tools by ‘watching’ YouTube videos

"Hmmm, I can do that." Robot watches videos to detect objects and how to grasp them (credit: Yezhou Yang et al.)

Imagine a self-learning robot that can enrich its knowledge about fine-grained manipulation actions (such as preparing food) simply by “watching” demo videos. That’s the idea behind a new robot-training system based on recent developments of “deep neural networks” in computer vision, developed by researchers at the University of Maryland and NICTA in Australia.

The objective of the system is to improve performance, improving on previous automated robot-training systems such… read more
