A Deeper U.S.-India Relationship

November 12, 2010

In his trip to India, President Obama announced Indian purchases of about $10 billion worth of American aircraft, locomotives, jet engines and gas turbines.

In exchange, the President announced American backing for a permanent seat for India on the Security Council.
Washington has also given a green light for high-technology exports to leading government agencies involved with space exploration, defense research and munitions development.

A Deluge of Data Shapes a New Era in Computing

December 16, 2009

Computational power created computational science, which produced
a “fourth paradigm” — the overwhelming flow of data that now requires a computing change, said Jim Gray, a database software pioneer and a Microsoft researcher, a few weeks before he was lost at sea off the California coast in January 2007.

The goal, he insisted, was not to have the biggest, fastest single computer, but rather “to have a world in… read more

A diabetes ‘breathalyzer’

Diabetes patients often receive their diagnosis after a series of glucose-related blood tests in hospital settings, and then have to monitor their condition daily through expensive, invasive methods. But what if diabetes could be diagnosed and monitored through cheaper, noninvasive methods?

Chemists at the University of Pittsburgh have demonstrated a sensor technology that could significantly simplify the diagnosis and monitoring of diabetes through breath analysis… read more

A Digital Health-Care Revolution

January 28, 2009

The more wired the hospital, the better off its patients: there are fewer deaths and complications, and lower bills. That’s the conclusion of a large study of Texas hospitals released earlier this week.

Unfortunately, only a small percentage of hospitals and doctors’ offices in the United States are wired, and the country lags far behind other developed nations in implementing such systems.

However, legislators and health-technology specialists hope… read more

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

z-space1

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

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
