“Los Alamos’ RAPTOR telescopes in New Mexico and Hawaii received a very bright cosmic birth announcement for a black hole on April 27,” said astrophysicist Tom Vestrand, lead author of a paper n the journal Science Nov. 21 that highlights the unusual event.

“This was the burst of the century,” said Los Alamos co-author James Wren. “It’s the biggest, brightest one to happen in at least 20 years, and… read more

It might be possible to restore lost memories

New UCLA research indicates that lost memories can be restored, offering hope for patients in the early stages of Alzheimer’s disease.

For decades, most neuroscientists have believed that memories are stored at the synapses — the connections between brain cells, or neurons — which are destroyed by Alzheimer’s disease. The new study provides evidence contradicting the idea that long-term memory is stored at synapses.

“Long-term memory is not… read more

Self-braking cars will save thousands of lives

October 8, 2012

How effective are systems that warn a driver about an impending front collision, then slam on the brakes if the driver doesn’t act quickly enough?

A lot, says a paper recently published in IEEE Transactions on Intelligent Transportation Systems, IEEE Spectrum Tech Talk reports.

Researchers at Virginia Tech’s Center for Injury Biomechanics studied systems that rely on radar to tell the car when it is coming… read more

Controlling heat like light

New approach using nanoparticle alloys allows heat to be focused or reflected just like electromagnetic waves
January 15, 2013

An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.

The approach relies on engineered materials consisting of nanostructured semiconductor alloy crystals.

Heat is a vibration of matter — technically, a vibration of the atomic lattice of a material — just as sound… read more

The future of cryonics debate between physicist Michio Kaku and Alcor CEO Max More

December 22, 2013

ALCOR2

In response to a question, “What are the practical applications of cryogenics today, and what potential improvements can we expect 20 to 30 years down the line?” Michio Kaku, PhD, replied with a critique.

Max More, PhD, CEO of Alcor Life Extension Foundation, offered this response, noting that cryonics is “affordable by regular people. Ice does not form inside cells… read more

Studying ethical questions as the brain’s black box Is unlocked

Excerpt from The New York Times
December 18, 2012

MRI Head

S. Matthew Liao, director of the bioethics program at New York University, has a singular title: neuroethicist.

Some researchers claim to be near to using fMRIs to read thoughts. Is this really happening?

The technology, though still crude, appears to be getting closer. For instance, there’s one research group that asks subjects to watch movies. When they

Michigan Technological University, scientists have replaced expensive ($1,500 an ounce) platinum in solar cells with low-cost 3D graphene.

Regular graphene is a two-dimensional form of carbon. Yun Hang Hu, the Charles and Caroll McArthur Professor of Materials Science and Engineering at MTU, and his team invented a way to synthesize a 3D version, with a honeycomb-like structure.

The 3D graphene had excellent conductivity and high… read more

In the new book Space Chronicles: Facing the Ultimate Frontier, Neil deGrasse Tyson says America is at a critical moment for future space exploration, as he explained to The Atlantic.

Give NASA the money it needs, he argues, and the agency will stimulate the economy and inspire students to pursue innovative, ambitious projects. (Say, for example, a way to thwart a wayward asteroid that could… 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

The PlayStation 4, as you’d expect for a seven-years-later follow-up, has impressively bumped specs. An eight-core X86 AMD “Jaguar” CPU and a 1.84 Teraflop AMD Radeon graphics engine (with “18 compute units”) comprise the central processing on the PS4, CNET reports.

There’s also 8GB of fast GDDR5 memory. The PS4 will use a hard drive for storage versus an SSD, but the included capacity in the box… read more
