A self-driving car equipped by GM spinoff Delphi Automotive completed today a historic, 3,500-mile journey across the U.S. from San Franscisco to New York.

The trip demonstrated the full capabilities of its active safety technologies with the longest automated drive ever attempted in North America. The coast-to-coast trip, launched in San Francisco on March 22, covered approximately 3,500 miles.

Demonstrated on the streets of Las Vegas at… read more

Rutgers researchers have used carbon nanotubes as a catalyst for splitting water into hydrogen and oxygen, which could replace expensive platinum for making clean-burning hydrogen fuel — which could one day replace expensive, environmentally harmful fossil fuels.

The Rutgers technology is also far more efficient than other low-cost catalysts investigated to date for electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen,… read more

A paper-thin flexible tablet computer

January 9, 2013

papertab

A flexible paper computer developed at Queen’s University in collaboration with Plastic Logic and Intel Labs could one day revolutionize the way people work with tablets and computers.

The PaperTab tablet looks and feels just like a sheet of paper. However, it is fully interactive with a flexible, high-resolution 10.7” plastic display developed by Plastic Logic, a flexible touchscreen, and powered by the second generation… read more

D-Wave Systems has broken the quantum computing 1000 qubit barrier, developing a processor about double the size of D-Wave’s previous generation, and far exceeding the number of qubits ever developed by D-Wave or any other quantum effort, the announcement said.

It will allow “significantly more complex computational problems to be solved than was possible on any previous quantum computer.”

At 1000 qubits, the new processor considers 21000 possibilities… read more

FDA OK’s ingestible sensor chip

Chip tracks adherence to oral medications, can report to caregiver
July 31, 2012

Injestible chip

Proteus Digital Health, Inc. announced Monday that the U.S. Food and Drug Administration (FDA) has cleared its ingestible sensor for marketing as a medical device.

The ingestible sensor (formally referred to as the Ingestion Event Marker or IEM) is part of the Proteus digital health feedback system, an integrated, end-to-end personal health management system designed to help improve patients’ health habits and connections to caregivers.… read more

Human muscle, regrown on animal scaffolding

September 17, 2012

Sergeant Strang has grown new leg muscle thanks to a thin sheet of material from a pig, The New York Times reports.

The material, called extracellular matrix, is the natural scaffolding that underlies all tissues and organs, in people as well as animals. It is produced by cells, and for years scientists thought that its main role was to hold them in their proper position.

But… read more

Nanoparticles reprogram immune cells to fight cancer

August 16, 2013

mitochondria-targeted NPs

Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer.

However, most cancerous cells are able to avoid detection by the immune system because they so closely resemble normal cells.

That leaves the cancerous cells free to multiply and grow into life-threatening tumors while the body’s… read more

How terahertz laser scanners will spy on you in airports

July 12, 2012

Genia

Genia Photonics has developed a programmable picosecond laser that is capable of spotting trace amounts of a variety of substances, including explosives, chemical agents, and hazardous biological substances at up to 50 meters.

It’s basically a spectrometer for radiation in the terahertz band. The beam used by Genia’s spectrometer is capable of penetrating most materials including wood, leather, cloth, ceramics, plastic, and paper, and can essentially… read more

A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor.

The researchers’ new imaging technique, based on the detection of calcium ions in neurons, could help them map the brain circuits that perform such functions.

It could also provide new insights into the… read more

First human brain-to-brain interface

August 28, 2013

uw_brain2brain_interface_1

University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other… read more

Finding ET may require giant robotic leap

April 24, 2012

NGC Galaxy

Autonomous, self-replicating robots — exobots — are the way to explore the universe, find and identify extraterrestrial life and perhaps clean up space debris in the process, according to John D. Mathews, professor of electrical engineering at Penn State.

“The basic premise is that human space exploration must be highly efficient, cost effective, and autonomous as placing humans beyond low Earth orbit is fraught with political… read more

Brain-boosting technique might help some functions while hurting others

transcranial_stimulation

Electrically stimulating the brain may enhance memory, but impede a person’s ability to react without thinking, MIT Technology Review reports.

Using a noninvasive technique called transcranial electrical stimulation (TES) to stimulate the brain, researchers found they could enhance learning when they targeted a certain spot.

But that also made people worse at automaticity, or the ability to perform a task without really thinking about it. Stimulating another… read more

iRobot files patent application for autonomous all-in-one 3D printing, milling, drilling and finishing robot

irobot_patent

Well, just when you thought 3D printing was finally putting you back in charge of creating your own stuff, along comes iRobot Corporation with a U.S. patent application for a “Robotic Fabricator.”

It’s conceived as a completely autonomous all-in-one product fabrication robot that handles manufacturing (including 3D printing) and all the post-printing work, from seed component to mature product, 3Ders reports.

Why Earth remains capable of supporting life despite CO2 greenhouse gas emissions

It's all in the rocks
March 23, 2014

WEB_Peru-Valley.jpg

“Fresh” rock — nature’s atmospheric carbon dioxide regulator — explains why the Earth has become neither sweltering like Venus nor frigid like Mars. So say researchers from USC and Nanjing University in China.

Scientists have long known that “fresh” rock pushed to the surface via mountain formation effectively acts as a kind of sponge, soaking up the greenhouse gas CO2.

Left unchecked, however, that process would… read more

New solar structure cools buildings in full sunlight, replacing air conditioners

Homes and buildings chilled without air conditioners? Car interiors that don't heat up in the summer sun? Tapping the frigid expanses of outer space to cool the planet? Yes.

sunlight_building

Stanford University researchers have designed an entirely new form of cooling structure that cools even when the sun is shining, eliminating the need for air conditioning.

Such a structure could vastly improve the daylight cooling of buildings, cars, and other structures by reflecting sunlight back into space.

“We’ve developed a new type of structure that reflects the vast majority of sunlight, while at the same… read more
