Web inventor warns of ‘dark’ net

May 24, 2006

Web inventor Tim Berners-Lee warned that if the US decided to go ahead with a two-tier Internet, the network would enter “a dark period.”

Web freedom faces greatest threat ever, warns Google’s Sergey Brin

April 16, 2012

The principles of openness and universal access that underpinned the creation of the Internet three decades ago are under greater threat than ever, according to Google co-founder Sergey Brin.

The threat to the freedom of the Internet comes, he claims, from a combination of governments increasingly trying to control access and communication by their citizens, the entertainment industry’s attempts to crack down on piracy, and the rise of “restrictive” walled gardens… read more

Web experts ask scientists to use the Web to improve understanding, sharing of their data in science

February 14, 2011

Fox and Hendler, both professors within the Tetherless World Research Constellation at Rensselaer Polytechnic Institute, outlined a new vision for the visualization of scientific data, in a perspective piece titled “Changing the Equation on Scientific Data Visualization.”

As the researchers explain, visualizations provide a means to enable the understanding of complex data. The problem with the current use of visualization in the scientific community, according to Fox… read more

Web browser pioneer backs new way to surf Net

November 10, 2010

A new browser called RockMelt is built on the premise that most online activity today revolves around socializing on Facebook, searching on Google, tweeting on Twitter and monitoring a handful of favorite websites.

Rockmelt tries to minimize the need to roam from one website to the next by corralling all vital information and favorite services in panes and drop-down windows.

Web Apps Meet Consumer Electronics at CES

January 8, 2010

A big trend emerging at CES: web applications like Pandora, Napster, iTunes being ported to consumer electronics, from the technology inside cars to Web-enabled TVs.

Web apps for bioinformatics

JavaScript apps to improve diagnostic accuracy, health-care delivery, and research-data sharing
July 24, 2012


A University of Alabama at Birmingham (UAB) team has developed ImageJS, a free app system that analyzes tissue images.

The ImageJS module enables pathologists to drag a digitized pathology slide into a Web app and analyze it for malignancy based on color. Cancer cells change color when exposed to standard dyes. It is available from the Google Chrome App storeGoogle Code and Github.

ImageJS… read more

Web accessibility soon mandatory in Europe?

June 18, 2006

The 25 European Commission member states and nine accession countries have all signed up for an “Internet for all” action plan, designed to ensure that the most Web-disadvantaged groups can get online.

The EC has pledged to increase broadband coverage across the continent to 90 percent by 2010 and to halve exclusion rates in skills and digital literacy by 2010.

Weaving Batteries into Clothes

October 9, 2007

A new machine that makes nanostructured fibers could turn soldiers’ uniforms into power supplies.

Among the machine’s many potential uses is assembling fibers in regular, nanoscale patterns that combine battery electrodes with a polymer separator and electrolyte to form a complete battery.

Wearing your computer on your sleeve

December 19, 2011

Over the last year, Apple and Google have secretly begun working on projects that will become wearable computers, based on the smartphone, which is becoming the hub for our information sharing and gathering, New York Times Bits reports.

In Google’s secret Google X labs, researchers are working on peripherals that — when attached to your clothing or body — would communicate information back to an … read more

Wearing a computer is good for you

Fitness trends and health-care problems are creating demand for tiny computers we won’t even notice we’re carrying.

What if your doctor had already received the information from a tiny device built into your cell phone, wallet, or undershirt? Sonny Vu, a cofounder of the medical-device company AgaMatrix, believes a device like this could fundamentally change health care.

He created the first FDA-approved glucose sensor that plugs into an iPhone;… read more

Wearables and electric vehicles may get boost from boron-infused graphene

May 19, 2015

Infusing the polymer in a laser-induced graphene supercapacitor (used to rapidly store and discharge electricity) with boric acid quadrupled the supercapacitor’s ability to store an electrical charge while greatly boosting its energy density (energy per unit volume), Rice University researchers have found.

The Rice lab of chemist James Tour uses commercial lasers to create thin, flexible supercapacitors by burning patterns into common polymers. The laser burns… read more

Wearable Wireless Displays Are In Sight

May 13, 2004
A "heads up" display from MicroOptical

Tiny wearable screens–with diagonals of less than half an inch–are now available that project what looks like a lifesize screen floating in space just a couple of feet from your eyes.

These devices permit the wearer to remain totally engaged with their environment, able to see everything around them.

Future screens won’t stick out, but rather will be embedded into the frames and will be wirelessly connected to… read more

Wearable silicon solar cells may soon become possible

A silicon-based optical fiber with solar-cell capabilities has been developed, scalable to many meters in length. The research may allow for weaving together solar-cell silicon wires to create flexible, curved, or twisted solar fabrics.

The findings by an international team of chemists, physicists, and engineers, led by John Badding, a professor of chemistry at Penn State University, build on earlier work addressing the… read more

Wearable sensors can alert you when you are getting sick, Stanford study shows

January 18, 2017

Fitness monitors and other wearable biosensors can tell when your heart rate, activity, skin temperature, and other measures are abnormal, suggesting possible illness, including the onset of infection, inflammation, and even insulin resistance, according to a study by researchers at the Stanford University School of Medicine.

The team collected nearly 2 billion measurements from 60 people, including continuous data from each participant’s wearable biosensor devices* and periodic data… read more
