Can a picture inflate the perceived truth of true and false claims?

Scientists discover the truth behind Colbert’s 'truthiness'
August 9, 2012

Trusting research over their guts, scientists in New Zealand and Canada examined the phenomenon that Stephen Colbert, comedian and news satirist, calls “truthiness” — the feeling that something is true.

In four different experiments they discovered that people believe claims are true, regardless of whether they actually are true, when a decorative photograph appears alongside the claim.

“We wanted to examine how the kinds of photos… read more

Can a new implant coating technique create a new six million dollar man?

June 30, 2009

An electrochemical process for coating metal implants to make them resemble biological material vastly improves their functionality, longevity and integration into the body a Tel Aviv University researcher has found.

Can a jellyfish unlock the secret of immortality?

November 29, 2012

The jellyfish can  transform itself back to a polyp, the organism’s earliest stage of life, author Nathaniel Rich writes in The New York Times.

During rejuvenation, it undergoes cellular transdifferentiation, an unusual process by which one type of cell is converted into another — a skin cell into a nerve cell, for instance. (The same process occurs in human stem cells.)

It is possible to imagine a… read more

Can a chip help computers see in 3D?

July 5, 2002

Silicon Valley start-up Tyzx believes it can give stereo vision to video cameras by encoding a processing scheme, based on the way humans see, into a custom chip. It could ready the way for robots with depth perception.
Its custom “DeepSea” chip runs an algorithm called “census correspondence” that finds similarities in real time across two streams of video images broken up into a square grid of 512 pixels.

CamSpace Creates a Wii For Everyone (Minus the Nintendo Console)

June 17, 2008

CamTrax’s CamSpace software converts nearly any object into an input device, using an ordinary PC webcam to track up to four objects–as small as 5mm–in real-time and with high accuracy and reliability.

Campaign to build 1837 Babbage’s Analytical Engine

October 20, 2010

Trial model of a part of the Analytical Engine, built by Babbage, as displayed at the Science Museum (London).

A campaign based in the UK is hoping to construct Charles Babbage’s steam-powered Analytical Engine, a prototype computer around the size of a steam locomotive, which Babbage designed in 1837.

While elements of the engine have been constructed in the past a complete working model has never been built.

The idea was the brainchild of author, science blogger and programmer John Graham-Cumming, who wrote the Geek Atlas.… read more

Camouflaging metamaterials create the LCD color display of the future

The secret: precision placement of plasmonic aluminum nanorods
September 16, 2014

Rice University’s new color display technology is capable of producing dozens of colors, including rich red, green and blue tones comparable to those found in high-definition LCD displays.<br />

The quest to create camouflaging metamaterials that can “see” colors and automatically blend into the background is one step closer to reality, thanks to a breakthrough color-display technology unveiled this week by Rice University‘s Laboratory for Nanophotonics (LANP).

The new full-color display technology uses aluminum nanorods to create the vivid red, blue and green hues found in today’s top-of-the-line LCD televisions and monitors.

Camero develops radar system to see thru walls

July 2, 2004

Israeli company Camero has developed a revolutionary technology that allows the user to see through walls and can be effectively used for both military and rescue services.

The UWB (ultra wideband) technology can produce real-time, three-dimensional pictures of what lies behind a wall, from a distance of up to 20 meters.

Cameras talk to each other to identify, track people

November 13, 2014

tracking subject

University of Washington electrical engineers have developed a way to automatically track people across moving and still cameras by using an algorithm that trains the networked cameras to learn one another’s differences. The cameras first identify a person in a video frame, then follow that same person across multiple camera views.

“Tracking humans automatically across cameras in a three-dimensional space is new,” said lead researcher Jenq-Neng Hwang,… read more

Cameraphone used to control computers in 3D

January 16, 2008

York University-developed prototype software allows a camera-equipped cellphone to control a computer as if the phone were a three-dimensional mouse.

On-screen items can be moved or manipulated simply by waving a handset in front of a screen.

Camera specs take candid snaps

September 25, 2003

A prototype pair of sunglasses with a camera built in to them has been created by Hewlett Packard researchers.

It allows for an unnoticeable wearable camera that can take pictures while being involved in events.

Camera sees behind objects

June 2, 2005

Researchers from Stanford University and Cornell University have put together a projector-camera system that can read a playing card that is facing away from the camera.

The dual-photography system gains information from a subject by analyzing the way projected patterns of light bounce off it.

Camera phones will be high-precision scanners

September 19, 2005

New cell-phone OCR software allows entire documents to be scanned simply by sweeping the phone across the page.

The software takes dozens of still images of the page and merges them, using the outline of the page as a reference guide.

Camera Phones Link World to Web

May 19, 2004

Semacode, a free system released this month, lets users scan bar codes on everyday objects with their camera phones and instantly pull up information about them. It’s an information bridge between the world and the Web.

Camera Firmware Hackers Build a Fully Open-Source Digicam

September 7, 2009

“Frankencamera,” an open-source digital camera built by Stanford computer- science researchers, will allow any programmer to write apps controlling any element of the camera’s performance, freely downloadable and installable by users of an under-$1,000 device.

One idea being explored is dynamic range expansion: taking multiple pictures of the same scene at varying exposures, and then compositing them into a single image in which each pixel is optimally lit.
