Tel Aviv University researchers hope to turn smartphones into powerful hyperspectral sensors that determine precise spectral data for each pixel in an image.

As with the Star Trek tricorder,* the enhanced smartphones would be capable of identifying the chemical components of objects from a distance, based on unique hyperspectral signatures.

The technology combines an optical component and image processing software, according to… read more

Researchers at NYU Langone Medical Center have captured images of dendrite nerve branches that show how mice brains sort, store, and make sense out of information during learning.

In a study published online in the journal Nature March 30, the NYU Langone neuroscientists tracked neuronal activity in dendritic nerve branches as the mice learned motor tasks such as how to run forward and backward on… read more

Penn State scientists have started their own crowd-funding campaign to bring brain-repair research from the lab into clinical trials.

The research team recently discovered a way to transform a support brain cell — called a glial cell — into healthy, functioning neural cells to replace nerves damaged by Alzheimer’s or Parkinson’s disease, brain or spinal-cord traumas, or stroke.

The campaign’s website features videos about the research, including a video… 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

UNSWTV | Google Maps for the Body

Biomedical engineer Melissa Knothe Tate at the University of New South Wales (UNSW) in Australia is using previously proprietary semiconductor technology to zoom through organs of the human body, down to the level of a single cell.

The imaging technology, developed by high-tech German optical and industrial measurement manufacturer Zeiss, was originally developed to scan silicon wafers for defects.… read more

Researchers build brain-machine interface to control prosthetic hand

Non-invasive technique allows amputee to control hand with his thoughts

A research team from the University of Houston has created an algorithm that allowed a man to grasp a bottle and other objects with a prosthetic hand, controlled only by his thoughts.

The technique, demonstrated with a 56-year-old man whose right hand had been amputated, uses non-invasive brain monitoring, capturing brain activity to determine what parts of the brain are involved in grasping an object.

With that information,… read more

A ‘Wikipedia’ for neurons

Carnegie Mellon University | NeuroElectro.org description

Carnegie Mellon University researchers have used data mining to create neuroelectro.org, a publicly available website that acts like Wikipedia, indexing the decades worth of physiological data collected about the billions of neurons in the brain.

The site aims to help accelerate the advance of neuroscience research by providing a centralized resource for collecting and comparing this “brain big… read more

‘Nanoneedles’ generate new blood vessels in mice, paving the way for new regenerative medicine

Scientists have developed “nanoneedles” that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice.

The researchers, from Imperial College London and Houston Methodist Research Institute in the U.S., hope their nanoneedle technique could ultimately help damaged organs and nerves repair themselves and help transplanted organs thrive.

In a trial described in Nature Materials, the team showed they could deliver nucleic… read more

A new microscopic shape-shifting probe capable of sensitive, high-resolution remote biological sensing has been developed by scientists at the National Institute of Standards and Technology (NIST) and the National Institutes of Health (NIH).

If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology, and engineering and ultimately used in clinical diagnostics, according to the researchers.

To date, most efforts… read more

Iron-metabolizing bacteria can load electrons from microscopic particles of magnetite (magnetic iron oxides) and later, discharge electrons to the microparticles, which could lead to a new way to clean up environmental pollution and other bioengineering applications, an international team of researchers have found.

For example, using light energy, magnetite can reduce (gain electrons from) the toxic form of chromium, chromium VI, converting it to the less toxic… read more

A nanolaser and a bendable-light material promise to speed up microelectronic devices

nanolaser-honeycomb ft.

University of Washington (UW) scientists have built a new nanometer-sized laser — using the thinnest semiconductor available today — that is energy efficient, easy to build, and compatible with existing electronics.

The UW nanolaser, developed in collaboration with Stanford University, uses a tungsten-based semiconductor only three atoms thick as light emitter.

The technology is described in a paper published in the March 16 online edition of read more

Researchers at University of Texas at Dallas (UT Dallas) have created a material made from nanofibers that can stretch to up to seven times its length while remaining tougher than Kevlar.

These structures absorb up to 98 joules per gram. Kevlar, often used to make bulletproof vests, can absorb up to 80 joules per gram. The researchers hope the structures will one day form material that can… read more

Researchers at MIT and Stanford University have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material to harvest a broader range of the sun’s energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations, the researchers say.

The new cell uses a layer of silicon — which forms the basis for most of today’s… read more
