Harvard scientists have created a type of “cyborg” tissue for the first time by embedding a three-dimensional network of functional, biocompatible, nanoscale wires into engineered human tissues.

The research team led by Charles M. Lieber, the Mark Hyman Jr. Professor of Chemistry at Harvard, and Daniel Kohane, a Harvard Medical School professor in the Departmentread 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

CocaCola

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

RealityDeck

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

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

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

Following Sandy, DHS seeks security ‘Cyber Reserve’

The damage to the electrical grid from Superstorm Sandy is just a taste of what could happen from a major cyberattack, says Department of Homeland Security (DHS) Secretary Janet Napolitano, CSO Security and Risk reports.

And a DHS task force said this week that one way to minimize that kind of risk is to recruit a “Cyber Reserve” of computer security pros that could be… read more

World’s First 3D printing photo booth to open in Japan

omote3D-photobooth-6

The world’s first “3D printing photo booth” is set to open for a limited time at the exhibition space EYE OF GYRE in Harajuku, Japan, Spoon & Tamago reports.

From November 24 to January 14, 2013, people with reservations can go and have their portraits taken. Except, instead of a photograph, you’ll receive miniature replicas of yourselves.

Reservations can be madke via… read more

Macaque monkeys have the anatomy for human speech, so why can’t they speak?

December 14, 2016

macaque

While they have a speech-ready vocal tract, primates can’t speak because they lack a speech-ready brain, contrary to widespread opinion that they are limited by anatomy, researchers at Princeton University and associates have reported Dec. 9 in the open-access journal Science Advances.

The researchers reached this conclusion by first recording X-ray videos showing the movements of the different parts of a macaque’s vocal anatomy — such as the tongue,… read more

Whole-body vibration may be as effective as regular exercise

March 16, 2017

Hate treadmills? The Tranquility Pod uses “pleasant sound, gentle vibration, and soothing light to transport the body, mind, and spirit to a tranquil state of relaxation” --- and maybe lose weight (and $30,000). (credit: Hammacher Schlemmer)

If you’re overweight and find it challenging to exercise regularly, now there’s good news: A less strenuous form of exercise known as whole-body vibration (WBV) can mimic the muscle and bone health benefits of regular exercise — at least in mice — according to a new study published in the Endocrine Society’s journal Endocrinology.

Lack of exercise is contributing to the obesity and diabetes epidemics, according to the researchers. These… read more

We can survive killer asteroids — but it won’t be easy

More than a thousand known asteroids are classed as “potentially hazardous,” based on size and trajectory, says astronomer Neil deGrasse Tyson in Wired Science.

Currently, it looks doable to develop an early-warning and defense system that could protect the human species from impactors larger than a kilometer wide. … Smaller ones, which reflect much less light and are therefore much harder to detect at great distances, carry enough energy to incinerate entire… read more

Elon Musk has launched a California-based company called Neuralink Corp., The Wall Street Journal reported today (Monday, March 27, 2017), citing people familiar with the matter, to pursue “neural lace” brain-interface technology.

Neural lace would help prevent humans from becoming “house cats” to AI, he suggests. “I think one of the solutions that seems maybe the best is to add an AI layer,” Musk… read more
