Firefighting robot creates 3D thermal imaging picture for rescuers

June 6, 2013

FFR is a robotic scout for firefighters developed by the Coordinated Robotics Lab at UC San Diego.

Engineers in the Coordinated Robotics Lab at the University of California, San Diego have developed new image processing techniques for rapid exploration and characterization of structural fires by small Segway-like robotic vehicles.

A sophisticated on-board software system takes the thermal data recorded by the robot’s small infrared camera and maps it onto a 3D scene constructed from the images taken by a pair of stereo… read more

Solving a 3.5 billion-year-old mystery

You can manipulate an existing memory simply by suggesting new or different information, Iowa State University researchers have shown.

The key is timing and recall of that memory, said Jason Chan, an assistant professor of psychology at Iowa State.

“If you reactivate a memory by retrieving it, that memory becomes susceptible to changes again. And if at that time, you give people new contradictory… read more

University of Washington computer scientists have developed gesture-recognition technology called “WiSee” that uses ambient Wi-Fi signals to detect specific movements (to turn off lights or flip through songs, for example )without needing sensors on the human body or cameras.

The team includes Shwetak Patel, an assistant professor of computer science and engineering and of electrical engineering and his lab.

By using an adapted Wi-Fi router… read more

OrCam, an Israeli start-up, has developed a camera-based system that gives the visually impaired the ability to read easily and move around freely.

It has an introductory price of $2,500, available in late 2013 and early 2014.

OrCam reads text and recognizes faces, locates bus numbers, monitors traffic lights, and identifies objects, products and places, and uses sound (via bone conduction) to convey information, the company… read more

Omni brings full-body VR gaming to Kickstarter

June 5, 2013

Omni

The Omni is a new virtual reality gaming device that launched a funding campaign Tuesday in  Kickstarter and, in a matter of hours, more than doubled its goal of $150,000, Digital Trends reports.

As of early Wednesday, the funding total is at more than $492,000. There are still 48 days left to go too, and the hope is that units will start shipping in January 2014.… read more

New method of mass-producing high-quality DNA molecules

June 5, 2013

A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods.

The new method can be of value to development of drugs consisting of DNA fragments and to DNA nanotechnology research.

The novel technique for manufacturing short, single-stranded DNA molecules — or oligonucleotides — has been developed by researchers at Karolinska Institute in Sweden and… read more

Brain makes its own version of Valium, Stanford scientists discover

Researchers at the Stanford University School of Medicine have found that a naturally occurring protein secreted only in discrete areas of the mammalian brain may act as a Valium-like brake on certain types of epileptic seizures.

The protein is known as diazepam binding inhibitor, or DBI. It calms the rhythms of a key brain circuit and so could prove valuable in developing novel, less side-effect-prone… read more

In the brain, cell-to-cell communication is dependent on neurotransmitters, chemicals that aid the transfer of information between neurons.

Several proteins have the ability to modify the production of these chemicals by either increasing or decreasing their amount, or promoting or preventing their secretion. One example is tomosyn, which hinders the secretion of neurotransmitters when in abnormal amounts.

Researchers at Bell Labs in New Jersey say they’ve used compressive sensing to build a camera that needs no lens and uses only a single sensing pixel to take photographs, MIT Technology Review reports.

What’s more, the images from this camera are never out of focus.

The invention could revolutionize optical, infrared and millimeter-wave imaging
