Elon Musk has decided that the next step for Tesla Motors cars is to go (mostly) autonomous, IEEE Spectrum reports.

From the Financial Times:
“We should be able to do 90 percent of miles driven within three years,” [Musk] said. Mr Musk would not reveal further details of Tesla’s autonomy project, but said it was “internal development” rather than technology being supplied by another company.read more

Simulated attack on the US power grid planned for Wednesday — Thursday

November 12, 2013

gridexii

The North American Electric Reliability Corporation (NERC) is quietly planning to launch a simulated attack on the U.S. power grid on Wednesday and Thursday (Nov. 13–14) called GridEx II, according to an unpublished document obtained by KurzweilAI from NERC.

The updated objectives for GridEx II are:

• Exercise the current readiness of the electricity industry to respond to a security incident, incorporating… read more

Nanomagnets may replace silicon-based transistors in computers, say UC Berkeley researchers

November 20, 2013

As the current passes through a strip of tantalum, electrons with opposite spins separate. This helps in orienting the nanomagnets  on the top of the tantalum strip such that they can be switched easily, which is also called "clocking". Thus information propagates from the input magnet along a chain of magnets and thus we perform nanomagnetic logic.

New work by University of California Berkeley researchers could one day make nanomagnetic switches a viable replacement for the conventional power-consuming transistors found in all computers.

“Increased energy consumption of modern day computers is a major challenge that the computer industry faces,” researcher Debanjan Bhowmik explained to KurzweilAI. Bhowmik is a UC Berkeley graduate student in the Department of Electrical Engineering and Computer Sciences and the first author of a paper on this… read more

Liquid air ‘offers energy storage hope’

October 2, 2012

wind farms

The Institution of Mechanical Engineers says liquid air can compete with batteries and hydrogen to store excess energy generated from renewables, BBC News reports.

IMechE says “wrong-time” electricity generated by wind farms at night can be used to chill air to a cryogenic state at a distant location. When demand increases, the air can be warmed to drive a turbine.

 

‘This house wants to defeat aging entirely’: de Grey vs. Blakemore

April 24, 2012

Aubrey de Grey

Oxford University Scientific Society is hosting a debate on Wednesday, April, 25, 2012, addressing whether aging should be a target of decisive medical intervention — raising the possibility of substantial extension of human lifespan.

Dr. Aubrey de Grey will propose the motion, “This house wants to defeat aging entirely“ and Professor Colin Blakemore will be opposing. The debate will be chaired and moderated by Professor Sir Richard… read more

MIT creates amazing UI from levitating orbs

In The Avengers, Tony Stark manipulates objects in thin air. MIT Media Lab researchers Jinha Lee and  Rehmi Post have actually created a similar tactile user interface for manipulating real floating objects in 3D space, called the ZeroN.

It’s essentially a small field in which gravity doesn’t overcome an object. Through the efforts of finely tuned electromagnetism, a user can place a metal ball in midair as easily… read more

Designing the exascale computers of the future

Tianhe-2-supercomputer

Several groups in Harvard’s School of Engineering and Applied Sciences (SEAS), are contributing to the basic science and engineering that will be needed to create the hardware and software for the next generation of supercomputers.

The goal: an exascale machine, performing at least 1018 (sextillian) operations per second — 30 times faster than the current fastest machine in the world, China’s Tianhe-2, capable of an Rmax* of 33.86… read more

Karlsruhe Institute of Technology (KIT) researchers have taken a big step towards miniaturizing magnetic data memory down to a single-atom bit: they fixed a single atom on a surface so the magnetic spin remained stable for ten minutes.

“A single atom fixed to a substrate is [typically] so sensitive that its magnetic orientation is stable only for less than a microsecond,” said Wulf Wulfhekel of KIT.

House to examine plan for United Nations to regulate the Internet

May 28, 2012

House lawmakers will consider an international proposal next week to give the United Nations more control over the Internet, Hillicon Valley reports.

The proposal is backed by China, Russia, Brazil, India and other UN members, and would give the UN’s International Telecommunication Union (ITU) more control over the governance of the Internet.

It’s an unpopular idea with lawmakers on both sides of the aisle in Congress,… read more

Gene-modified cow makes milk rich in protein, study finds

October 2, 2012

cows

Scientists have altered the genes of a dairy cow to produce milk that’s rich in a protein used in numerous food products and lacking in a component that causes allergies in humans.

Using a process called RNA-interference that turns certain genes on or off, scientists from New Zealand produced a cow whose milk had increased casein, a protein used to make cheese and other foods, and almost no… read more

Record 100,000 entangled photons detected

October 31, 2012

A whopping 100,000 entangled photons have been detected for the first time, beating the previous record of just 12, New Scientist reports.

The technique could be useful for safely sharing keys used in encrypted communications.

Entangled photons have linked quantum states, such that measuring the state of one photon determines the state of the others, no matter how far apart they are.

Detecting entanglement usually… read more

UCSD introduces Diego-san, a baby robot with ‘tude

UCSD has introduced Diego-san, a new humanoid robot who mimicks the expressions of a one-year-old child

Demonstrated at CES and in a video, the robot will be used in studies on sensory-motor and social development — how babies “learn” to control their bodies and to interact with other people.

Diego-san’s hardware was developed by two leading robot manufacturers: the head by Hansonread more

UC San Francisco neuroscientist Adam Gazzaley, MD, PhD, is hoping to paint a fuller picture of what is happening in the minds and bodies of those suffering from brain disease with his new lab, Neuroscape, which bridges the worlds of neuroscience and high-tech.

Gazzaley aims to eliminate the need to immobilize subjects inside big, noisy machines or tether them to computers — making… read more

High-capacity 3D transparent memory a step closer to reality

October 4, 2012

Transparent Memory

Rice University researchers led by chemist James Tour have just written a paper in the journal Nature Communications that describes transparent, non-volatile, heat- and radiation-resistant memory chips created in Tour’s lab from silicon oxide sandwiched between electrodes of graphene, the single-atom-thick form of carbon.

More than four years ago, they discovered it was possible to make bits of computer memory from silicon and carbon, but make them much smaller and perhaps better than anything… read more

Crowdsourcing — posing a question or asking for help from a large group of people — has allowed many problems to be solved, like scan for new galaxies and climate modeling, that would be impossible for experts alone..

But what if the crowd was asked to decide what questions to ask in the first place?

University of Vermont researchers Josh Bongard and Paul Hines decided to explore  that question… read more
