Exercise reorganizes the brain to reduce stress and anxiety

July 5, 2013


Physical activity reorganizes the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function, according to a Princeton University research team.

The researchers report in the Journal of Neuroscience that when mice allowed to exercise regularly experienced a stressor — exposure to cold water — their brains exhibited a spike in the activity of neurons… 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

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

Delphi completes first coast-to-coast automated drive

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

A computerized house that generates as much energy as it uses

NIST unveils net-zero energy residential test facility to improve testing of energy-efficient technologies
September 18, 2012

NIST Net Zero Energy Residential Test Facility

The U.S. Commerce Department’s National Institute of Standards and Technology (NIST) has unveiled a laboratory in the form of a typical suburban home, designed to demonstrate that a family of four can generate as much energy as it uses in a year.

The two-story, four-bedroom, three-bath “Net-Zero Energy Residential Test Facility“ was built to U.S. Green Building Council LEED Platinum standards — the highest standard for sustainable… read more

Stumped by a problem? The ‘generic parts technique’ technique unsticks you

March 8, 2012


University of Massachusetts psychologist Dr. Tony McCaffrey has developed a systematic way of overcoming “functional fixedness” (the tendency to fixate on the common use of an object or its parts, hindering people from solving problems). He calls it the “generic parts technique” (GPT).

He found that people trained in GPT solved eight problems 67 percent more often than those who weren’t trained, and the trained group… read more

Homeland Security looking for (more than) a few good drones

DHS to test unmanned aircraft for variety of applications.

The U.S. Department of Homeland Security this week issued a call for unmanned systems makers to participate in a program that will ultimately determine their safety and performance for use in first responder, law enforcement and border security situations, Network World Layer 8 reports.

In a twist that will certainly raise some eyebrows,  the program’s results  of… read more

Easing brain fatigue with a walk in the park

An innovative new study from Scotland confirms the observation that you can ease brain fatigue simply by strolling through a leafy park, The New York Times reports.

Researchers have long theorized that green spaces are calming, requiring less of our so-called directed mental attention than busy, urban streets do, but it had not been possible to study the brains of people while they were actually outside, moving… read more

The highest-resolution immersive visualization facility ever built

November 21, 2012


Stony Brook University (SBU) recently unveiled its new Reality Deck, with 1.5 billion pixels total on 416 super-high-resolution screens in a four-walled surround-view theater — the highest-resolution  immersive display ever built — and driven by a 220 TFLOPs graphic supercomputer.

Its purpose and primary design principle is to enable scientists, engineers, and physicians to tackle current problems that require the visualization of vast amounts of… read more

Brain cells made from urine

December 11, 2012


Some of the waste that humans flush away every day could become a powerful source of brain cells to study disease, and may even one day be used in therapies for neurodegenerative diseases.

Scientists have found a relatively straightforward way to persuade the cells discarded in human urine to turn into valuable neurons, Nature News reports.

The method uses ordinary cells present in urine, and transforms… read more

Assembling big structures out of small ultralight pieces

"Can you 3-D print an airplane?" question leads to major design breakthrough
August 19, 2013

Assemblies of the cellular composite material are seen from different perspectives, showing the repeating "cuboct" lattice structure, made from many identical flat cross-shaped pieces.<br />

MIT researchers have developed a lightweight structure whose tiny blocks can be snapped together much like the bricks of a child’s construction toy.

The new material, the researchers say, could revolutionize the assembly of airplanes, spacecraft, and even larger structures, such as dikes and levees.

The new approach to construction is described in a paper appearing in the journal Science, co-authored by postdoc Kenneth Cheung and… read more

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

December 22, 2013


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
