Fighting Sleep: Researchers Reverse Cognitive Impairment Caused By Sleep Deprivation

October 27, 2009

A University of Pennsylvania research team has found a molecular pathway in the brain that is the cause of cognitive impairment due to sleep deprivation.

The impairment may however be reversible by reducing the concentration of a specific enzyme that builds up in the hippocampus of the brain, they found.

Hot Off the Presses, New Skin for Burn Victims

February 22, 2011

Using skin cells as ink and a human body as paper, James Yoo of Wake Forest University School of Medicine in Winston-Salem, North Carolina has designed a printer that can analyze a burn. First, it uses a laser scanner to determine the exact size and shape of the lesion. Then it creates a 3D reconstruction. Finally, it prints the layers of different cells needed — all in less than an… read more

Toxoplasma Parasite Mind Control

February 13, 2006

Half of the world’s human population is infected with Toxoplasma gondii, parasites in the body — and the brain.

Dr. E. Fuller Torrey (Associate Director for Laboratory Research at the Stanley Medical Research Institute) noticed links between Toxoplasma, a common parasite found in the guts of cats, and schizophrenia in human beings, approximately three billion of whom are infected with T. gondii.

Second Family of High-Temperature Superconductors Discovered

(Kamihara et al.)

Researchers in Japan and China have discovered a new family of iron-and-arsenic compounds that operate as high-temperature superconductors. Physicists are hailing the discovery as a major advance.

Shaking up system of quake predictions

May 6, 2003

“A seismologist in Wisconsin and a geophysicist in California have developed an alarm system that promises to offer at least a few crucial seconds of warning that a major quake is about to strike. Simulations so far suggest that the technique can signal a quake’s magnitude and where the most dangerous ground motion might threaten people and buildings.”

Singularity University Kicks Off First Executive Program

November 6, 2009

Singularity University (SU) will launch the SU Executive Program at the NASA Ames Research Center, Moffett Field, Calif. on Saturday.

The nine-day program is designed to educate, inform and prepare executives for the imminent disruption and opportunities resulting from exponentially accelerating technologies.

The SU Executive Program addresses six fields experiencing exponentially accelerating change: AI and Robotics, Nanotechnology, Biotechnology and Bioinformatics, Medicine and Human Machine Interface, Networks… read more

Radio for the YouTube Era?

March 1, 2011

Broadcastr, a Brooklyn-based start-up whose service went live on a public beta site on Monday, collects audio clips from various sources and pins them to physical locations, so people can be fed stories, audio tour guides and historical clips that are relevant to their physical locations.

Playlists can also be formed based on subject matter or source. The start-up’s founders see the project as a tool for… read more

Is our universe about to be mangled?

February 23, 2006

Our universe may one day be obliterated or assimilated by a larger universe, according to a controversial new analysis. The work suggests the parallel universes proposed by some quantum theorists may not actually be parallel but could interact — and with disastrous consequences.

Photoluminescence in nano-needles

April 23, 2008

Scientists at the University of California, Berkeley have grown gallium-arsenide structures into the shape of narrow needles which, when optically pumped, emit light with high brightness.

In addition to optoelectronic devices, the needles could be valuable in such applications as atomic force microscopy (AFM), where the sharp tips can be grown in arrays without further etching or processing steps.

Some believe that AFM arrays, besides speeding up the… read more

Telescopes of the World, Unite! A Cosmic Database Emerges

May 20, 2003

In the past 25 years, the number of CCD pixels (each acting as a miniature astronomical instrument) in all the world’s telescopes has exponentially increased by a factor of 3,000, a beneficiary of Moore’s Law.

The resulting total amount of astronomical data collected every year is doubling; surveys of millions of astronomical objects now contain about 100 terabytes of distributed data in the “National Virtual Observatory.”

Digital ‘Cloud’ could form over London for the 2012 Olympics

November 12, 2009

digital-cloud-11-11-09

MIT researchers have proposed to build a tourist attraction called “The Cloud” in London for the 2012 Olympics.

The structure would consist of two 400-foot tall mesh towers that are linked by a series of interconnected plastic bubbles, which would themselves house an observation deck inside and be used to display everything from Olympic scores and highlights to a “barometer of the city’s interests and moods” outside.

How to discover asteroid impacts

March 12, 2006

An amateur geologist has demonstrated the power of the Internet with his discovery of two impact craters, using free distributed software (Google Earth, NASA World Wind).

New nanotech products hitting the market at the rate of 3 to 4 per week

April 25, 2008

New nanotechnology consumer products are coming on the market at the rate of 3 to 4 per week, Project on Emerging Nanotechnologies (PEN) Project Director David Rejeski said in testimony before the Senate Commerce Committee Thursday.

The number of consumer products using nanotechnology has grown from 212 to 609 since PEN launched the world’s first online inventory of manufacturer-identified nanotech goods in March 2006. Health and fitness items, which… read more

A wearable to help measure stress, epileptic seizures, activity, and sleep

November 24, 2014

MIT spinoff Empatica, which is developing a medical-quality wearable device to monitor epileptic seizures* and alert caregivers, has launched an Indiegogo crowdfunding campaign to fund its development.

“When people that have epilepsy wear Embrace, they will get an alert when an unusual event happens, like a convulsive seizure,” the Indiegogo site says. “It will go via their smartphone to parents, roommates or caregivers, so somebody can check… read more

CIA Developing Software to Scour Photos

June 2, 2003

The CIA is bankrolling efforts to improve technology designed to scour millions of digital photos or video clips for particular cars or street signs or even, some day, human faces.

The innovative software promises
to help analysts make better use of the CIA’s enormous electronic archives. Analysts also could be alerted whenever a helicopter or other targeted item appeared in a live video broadcast.
