corneal reflections - featured

The pupil* of the eye in a photograph of a face can be mined for hidden information, such as reflected faces of the photographer and bystanders, according to research led by Dr. Rob Jenkins, of the Department of Psychology at the University of York and published in PLOS ONE (open access).

The researchers say that in crimes in which the victims are photographed, such as hostage… read more

Yes. A space elevator appears possible and space elevator infrastructure could indeed be built via a major international effort, a study conducted by experts under the auspices of the International Academy of Astronautics has found, Space.com writer Leonard David reports.

Two technologies pacing the development of the space elevator are an ultra-strong space tether and other space elevator components, and lightweight solar cells, according to study lead… read more

Laser could trigger rain and lightning

April 22, 2014

Illustration of a high-intensity laser dressed with a secondary laser that helps provide fuel to extend the distance of the primary beam.

Researchers at the University of Central Florida’s College of Optics & Photonics and the University of Arizona have further developed a new technique to aim a high-energy laser beam into clouds to make it rain or trigger lightning.

The solution: surround the beam with a second beam to act as an energy reservoir, sustaining the central beam to greater distances than previously possible. The secondary “dress” beam… read more

Wearable ‘neurocam’ records scenes when it detects user interest

February 10, 2014

Neuroware

Keio University scientists have developed a “neurocam” — a wearable camera system that detects emotions, based on an analysis of the user’s brainwaves.

The hardware is a combination of Neurosky’s Mind Wave Mobile and a customized brainwave sensor.

The algorithm is based on measures of “interest” and “like” developed by Professor Mitsukura and the neurowear team.

The users interests are quantified… read more

Disney Research 3-D printer can combine fabrics, wiring

April 20, 2015

layered fabric 3D printed objects-ft

A team from Disney Research, Carnegie Mellon University and Cornell University have devised a 3-D printer that layers together laser-cut sheets of fabric to form soft, squeezable objects such as phone cases and toys. These objects can have complex geometries and incorporate circuitry that makes them interactive.

“Today’s 3-D printers can easily create custom metal, plastic, and rubber objects,” said Jim McCann, associate… read more

Graphene antennas would enable terabit wireless downloads

March 6, 2013

Researchers at Georgia Tech have drawn up blueprints for a wireless antenna made from atom-thin sheets of carbon, or graphene, that could allow terabit-per-second transfer speeds at a range of about one meter, MIT Technology Review reports

This would make it possible to obtain 10 high-definition movies by waving your phone past another device for one second. At even shorter ranges, such as a few centimeters, data… read more

NASA video on LENR (low energy nuclear reactions), a clean form of nuclear energy

January 13, 2012

NASA Langley Research Center posted Thursday (but has not announced) a new video on NASA research on LENR (low energy nuclear reactions), entitled “Method for Enhancement of Surface Plasmon Polaritons to Initiate & Sustain LENR.”

The research focuses on “another way of producing energy-efficient nuclear power,” says NASA Senior Research Scientist Joseph Zawodny, featured in the video (posted on YouTube by KurzweilAI). “This other form of nuclear power releases… read more

Memory implants

A maverick neuroscientist believes he has deciphered the code by which the brain forms long-term memories
May 1, 2013

Teodore Berger, a biomedical engineer and neuroscientist at the University of Southern California in Los Angeles, envisions a day in the not too distant future when a patient with severe memory loss can get help from an electronic implant, MIT Technology Review reports.

In people whose brains have suffered damage from Alzheimer’s, stroke, or injury, disrupted neuronal networks often prevent long-term memories from forming. For more than… read more

What zebrafish can teach us about healing brain damage

The zebrafish regenerates its brain after injury, unlike mammals. Is there something we can learn about the process that might help with traumatic brain injury  and neurodegenerative disorders?

A research team at the Center for Regenerative Therapies Dresden (CRTD), Germany decided to investigate.

They found that that in zebrafish — in contrast to mammals — inflammation is a positive regulator of neuronal regeneration in the… read more

A new 3D printing process using human stem cells could pave the way to custom replacement organs for patients, eliminating the need for organ donation and immune suppression, and solving the problem of transplant rejection.

The process, developed at Edinburgh-based Heriot-Watt University, in partnership with Roslin Cellab, could also speed up and improve the process of reliable, animal-free drug testing by growing three-dimensional human tissues and structures… read more

Google isn’t just the backbone of the Internet anymore, writes Steve Kovach at Business Insider.

“It’s rapidly becoming the backbone of your entire life, all thanks to data you’re voluntarily giving up to a private company based on your Web searches, photos, Gmail messages, and more. …

“It’s the most apparent in Google Now, a voice-powered personal assistant that launched on Android phones last year.” [...]

Researchers at the U.S. Department of Energy’s Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies.

Magnetic switching is used to encode information in hard drives, magnetic random access memory and other computing devices. The discovery, reported in the April 4 issue… read more
