A Digital Life

February 21, 2007

New systems may allow people to record everything they see and hear–and even things they cannot sense–and to store all these data in a personal digital archive

Microsoft Research’s Gordon Bell has launched a research project, called MyLifeBits, aimed at creating a digital archive of all his interactions with the world. Bell’s digital memories include documents from his long career in the computer industry, all the photographs he takes… read more

A digital ‘magazine’ with one subscriber

March 10, 2011

Zite is an iPad app that crawls a half million Web domains to find specific reading material that would be of interest to you, according to your social network and/or online reading behavior.

It evaluates this potential content by tracking signals (like tweets, comments, tags and sharing) from stories that indicate a certain level of social interest and momentum in the story. The result is a personalized magazine that… read more

A Digital World With Analog as Its Workhorse

August 9, 2004

The digital revolution is driving strong demand for advances in analog electronics.

A Dim View of a ‘Posthuman Future’

April 7, 2002

In a new book, “Our Posthuman Future,” political theorist Francis Fukuyama warns that biotechnology may disruptively alter human nature.Fukuyama, who is also the author of “The End of History and the Last Man,” is concerned about genetic engineering of the human germline, mood-altering drugs, and major increases in human longevity, all of which could change society and alter the balance of human nature and cause us to “lose our humanity,”… read more

A display that makes interactive 3D seem mind-bogglingly real

The Z Space display could be revolutionary for designers and animators, but might also inspire innovation in computer gaming and augmented reality
December 19, 2012

The “Z Space” display, developed by Californian company Infinite Z, tracks a user’s eye and hand movements and adjusts the 3-D image that he or she sees in real-time, MIT Technology Review reports.

The resulting effect is stunning. Unlike the 3-D video seen in a movie theater or on a 3-D TV, you can move your head around an object — to look it from… read more

A Display That Tracks Your Movements

June 20, 2008

Samsung and interactive advertising company Reactrix Systems plan to bring 57-inch interactive displays to Hilton hotel lobbies by the end of the year.

These displays can “see” people in 3D standing up to 15 feet away from the screen as they wave their hands to play games, navigate menus, use maps –and interact with ads.

A DIY medical diagnosis app

March 23, 2014

colorimetric test featured

Colorimetrix, a new app developed by University of Cambridge researchers, turns a smartphone into a portable medical diagnostic device.

The app could make monitoring conditions such as HIV, tuberculosis, malaria, diabetes, kidney disease, and urinary tract infections clearer and easier for both patients and doctors, and could eventually be used to slow or limit the spread of pandemics in the developing world, the researchers say.… read more

A DNA nanocage for transporting drugs in the body

December 4, 2013

A method for developing a “nanocage” — which may eventually enable transport of medications in the body to target diseased cells — has been developed by researchers at Aarhus University and colleagues in Italy and the U.S.

Using DNA self-assembly, the researchers designed eight unique DNA molecules from the body’s own natural DNA molecules. When these DNA molecules are mixed together, they spontaneously aggregate in… read more

A ‘DNA nanotrain’ for targeted cancer drug transport

Targeted chemotherapy delivery without toxic side-effects

Chemotherapy drugs are specifically transported to target cancer cells, unloaded, and induce cytotoxicity to cancer cells (credit: )

University of Florida researchers have developed a “DNA nanotrain” that fast-tracks its payload of cancer-fighting drugs and bioimaging agents to tumor cells deep within the body.

The nanotrains can cost-effectively deliver high doses of drugs to precisely targeted cancers and other medical maladies without leaving behind toxic nano-clutter.

DNA nanotechnology holds great promise as a new way to deliver chemotherapy directly to cancer cells, but… read more

A DNA Success Raises Bioterror Concern

January 12, 2005

Researchers have made an unexpectedly sudden advance in synthesizing long molecules of DNA, creating concern the technique might be used to create the smallpox virus.

“This has the potential for a revolutionary impact in the ease of synthesis of large DNA molecules,” said Dr. Richard Ebright, a molecular biologist at Rutgers University.

“This will permit efficient and rapid synthesis of any select agent virus genome in very short… read more

A DNA-based nanosensor that detects cancer by its pH

May 13, 2014

Bioengineers at the University of Rome, Tor Vergata and the University of Montreal have used DNA to develop a tool that detects and reacts to chemical changes caused by cancer cells. It may one day be used to deliver drugs to tumor cells.

The researchers’ nanosensor measures pH variations at the nanoscale, indicating how acidic (a lower pH level) or alkaline (a higher pH level).… read more

A doctor in your pocket

January 16, 2012

Most of the conditions that kill us, including cancer and heart disease, could be prevented or delayed by a new way of looking at and treating health: personalized medicine using tiny health monitors and tailored therapies, leading to the end of illness.

A Doll That Can Recognize Voices, Identify Objects and Show Emotion

August 26, 2005

Using an advanced speech-recognition/voice response chip, an electronic memory, and facial motors, Amazing Amanda, scheduled for release next month by Playmates Toys, will “listen, speak and show emotion,” with responses customized to the individual child.

A Dose Of Genius

June 12, 2006

The use of “smart pills” that increase concentration, focus, wakefulness and short-term memory is soaring.

A Dream Interpretation: Tuneups for the Brain

November 11, 2009

Dr. J. Allan Hobson, a psychiatrist and sleep researcher at Harvard, argues that dreaming is a parallel state of consciousness that is continually running but normally suppressed during waking. This is supported by research on lucid dreaming, which has been found to have elements of both rapid-eye-movement (REM) sleep and of waking.

Hobson argues that the main function of REM, when most dreaming occurs, is physiological: the brain is… read more
