Patients Find ‘Gut-Cam’ Technology Easy to Swallow

January 3, 2003

The M2A disposable diagnostic capsule, also called the “gut cam,” is the first of its kind: a self-contained, miniature, disposable color video system designed to travel painlessly through the digestive system, continuously capturing images along the way to spot tumors, internal bleeding and lesions.

The University of Manchester’s Jodrell Bank Observatory has been chosen as the headquarters for a $2 billion effort to build the world’s largest and most sensitive radio telescope, the Square Kilometre Array (SKA).

The SKA will be capable of answering some of the most fundamental questions about the Universe, including dark energy, how the first stars and galaxies formed after the Big Bang, how galaxies… read more

Scientists propose new hypothesis on the origin of life

September 4, 2009

Life on Earth originated at photosynthetically-active porous structures made of zinc sulfide, similar to deep-sea hydrothermal vents, under the high pressure of a carbon-dioxide-dominated atmosphere, suggest scientists from the University of Osnabrueck, Germany and U.S. National Institutes of Health.

Saving the Net: How to Keep the Carriers from Flushing the Net Down the Tubes

November 17, 2005

“Are you ready to see the Net privatized from the bottom to the top? Are you ready to see the Net’s free and open marketplace sucked into a pit of pipes built and fitted by the phone and cable companies and run according to rules lobbied by the carrier and content industries?

“Do you believe a free and open market should be ‘Your choice of walled garden’ or ‘Your… read more

Remote Microscopy: a modular microscope attachment for cell phones

March 19, 2008

University of California, Berkeley researchers have developed a modular, high-magnification microscope attachment for cell phones, enabling health workers in remote areas to take high-resolution images of blood samples and then transmit the photos to experts at medical centers.

The researchers say the cameras in late-model phones are capable of capturing all the details that a doctor would need to identify malaria parasites and cancer cells.

DNA barcode provides virtually unlimited color patterns for tagging molecules and cells

New technology could launch biomedical imaging to next level
September 25, 2012

DNA Barcode Nanotube

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have created a new kind of barcode (colored fluorescent biomarkers) that could come in an almost limitless array of styles — with the potential to enable scientists to gather vastly more vital information, at one given time, than ever before.

The new method harnesses the natural ability of DNA to self-assemble.

A day at the office in 2013

January 20, 2003

We are at the beginning of an era of pervasive digital intelligence. When RFID and other sensors are pervasive, cost less than a penny, have more chip-to-chip intelligence, and transmit at distances far beyond 15 feet or even 300 feet, the potential for abuse will be significant.

AR interface keeps information simplified

April 11, 2011

Researchers at the University of Tokyo have built an augmented reality (AR) interface that keeps information simplified until the user focuses on it.

The interface has an eye-tracking system that allows interaction to be driven entirely by gaze direction. It displays objects that demand attention in the user’s peripheral vision as simple icons that can be processed even by the limited visual acuity of human peripheral vision.

If a user… read more

Virtual maps for the blind

September 14, 2009

BlindAid, a virtual “”white cane” system that allows the blind to explore the world around them using a 3-D haptic device (a joystick that allows them to “feel” the world — it stiffens when the user meets a virtual wall or barrier, for example) has been developed by researchers at Tel Aviv University and MIT.

Brighter Nanotubes

November 29, 2005

IBM researchers have fabricated nanotube devices around 1,000 times more efficient than previous ones at emitting light.

Such light-emitting nanotubes could find applications in creating faster transistor interconnections and in telecommunications. The tubes emit light in the wavelengths used by the telecom industry to send information through optical fibers.

The nanotubes, which produce tightly focused light, could also be used for optical probing, manipulation, and spectroscopic analysis at… read more

Imaging the Genetic Profile of a Tumor

March 25, 2008

University of California at San Diego researchers have found evidence that the appearance of brain cancer tumors in magnetic resonance images (MRIs) can be used to predict the cancer’s genomic profiles–traits associated with how the tumors grow or react to treatment.

They looked for connections between the ten types of tumors shown in the MRIs and genetically linked cancer characteristics such as blood-vessel growth and cell proliferation by studying… read more

Utopia 2.0

February 10, 2003

Dave Biggs, a systems manager at the University of British Columbia’s Sustainable Development Research Institute, helps people of different philosophical backgrounds forge a common future with an innovative Web-based game called QUEST, which lets tens of thousands of users model and reshape the future of the towns where they live.

Low-cost motion-sensing programs

April 15, 2011

Predator Camera

Microsoft has announced Kinect support for Netflix for the Xbox 360 on April 14 along with a software development kit for do-it-yourself motion-sensing programmers — but a new open-source program called Predator promises to be cheaper.

Kinect for Netflix allows voice or gesture control of the Netflix interface to select any content, including playback, fast forward, and rewind.

Microsoft says the Kinect… read more

Text-to-Speech Technology Reaches an Inflection Point

September 18, 2009

People with speech-impairing conditions like A.L.S., autism, Down syndrome and strokes have started to discover that general-purpose devices, such as iPhones and netbooks equipped with downloadable text-to-speech software, can in many cases help them communicate better and more cheaply than the expensive proprietary speech devices covered by Medicare and private health insurance.

In addition, disease experts say that children with Down syndrome often prefer to have a standard computer… read more

Breakthrough chip delivers better digital pictures for less power

December 10, 2005

University of Rochester researchers have designed a prototype chip that can directly digitize each pixel location in a CMOS sensor and they plan a second technology that will compress the image with far fewer computations than the best current compression techniques while increasing dynamic range 100 times.

The new technologies may enable imaging chips to use just a fraction of the energy used today and capture high-resolutoin images while… read more
