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

First human brain-to-brain interface

August 28, 2013

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

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

It's all in the rocks
March 23, 2014

“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

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

Solar-powered 3-D printer prints glass from sand

June 29, 2011

Solar Sinter

Markus Kaiser’s  solar sintering project explores the potential of desert manufacturing, where energy and material occur in abundance.

In this experiment, sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, combining natural energy and material with high-tech production technology.

His work with solar-sintering aims to raise questions about the future of manufacturing and the use of solar energy.… read more

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

Catching up with Nevada, it will be legal for autonomous cars to drive in California, probably within the next five years, if Gov. Brown signs SB 1298, just passed by the California Senate, the San Jose Mercury reports.

The bill charges the DMV by January 2015 with determining standards for vehicles and rules.

Automakers would have to get their vehicles approved by the state, and then licensed… 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

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

January 28, 2013

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.

Further proof for controversial quantum computer

April 29, 2013

dwave_ones_in_the_lab_large

Is the world’s only commercial quantum computer really a quantum device, or a just regular computer in disguise? Controversy has long swirled around the computer produced by D-Wave, a company based near Vancouver, Canada.

Now a paper published on the arXiv preprint server takes a step forward in showing that it really does operate on a quantum level, Nature News Blog reports.

Bitcoin price soars above $9 for the first time in almost a year

July 19, 2012

bitcoinaccepted

The price of Bitcoins surged this week, rising above $9 for the first time in almost a year, Ars Technica reports. The increase suggests growing public interest in the peer-to-peer cryptocurrency.

Vices like pornography and gambling continue to be a significant factor in the currency’s value.

But other new uses for the currency continue to pop up. Coinbase, a startup aiming to… read more

A low-cost water splitter that runs on an ordinary AAA battery

Could allow for true zero-emissions fuel-cell vehicles and save hydrogen producers billions of dollars in electricity costs
August 22, 2014

Stanford scientists have developed a low-cost device that uses an ordinary AAA battery to split water into oxygen and hydrogen gas. Gas bubbles are produced by electrodes made of inexpensive nickel and iron.

A cheap, emissions-free device that uses a 1.5-volt AAA battery to split water into hydrogen and oxygen by electrolysis has been developed by scientists at Stanford University.

Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive, abundant nickel and iron.

“This is the first time anyone has used non-precious metal catalysts to split water at a voltage… read more

Hawking offers new solution to ‘black hole information paradox’

New hope if you fall into a black hole

Addressing a current controversy in physics about information in black holes, “I propose that the information is stored not in the interior of the black hole as one might expect, but on its boundary, the event horizon.”

The event horizon is a boundary around a black hole beyond which events cannot affect an outside observer, also known as “the point of no return” — where gravitational pull… read more

Berkeley Lab scientists record first inside look at carbon-capture molecular structure

November 26, 2013

Mg-MOF-74 is an open metal site MOF whose porous crystalline structure could enable it to serve as a storage vessel for capturing and containing the carbon dioxide emitted from coal-burning power plants. (National Academy of Sciences)

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) have recorded the first electronic structure observations of the adsorption of carbon dioxide inside a metal-organic framework (MOF).

The “Mg-MOF-74″ MOF’s porous crystalline structure could enable it to serve as a storage vessel for capturing and containing the carbon dioxide emitted from coal-burning power plants.

MOFs are molecular systems consisting of a metal oxide center surrounded by organic… read more
