What Comes After Web 2.0?

December 4, 2006

Today’s primitive prototypes show that a more intelligent Internet is still a long way off.

Most of the current projects are so far from producing practical tools–let alone services that could be commercialized–that it’s premature to say they represent a “third generation” of Web technology. For that, judging from today’s state of the art, we’ll need to wait another few years.

What comes after the cloud? How about the fog?

Startup Symform thinks it can provide better disaster resilience than even data centers hundreds of miles apart. And, says Bassam Tabbara, Symform cofounder and Chief Technical Officer, it can do that in a way that’s extremely cheap — and in some cases free — to its customers, Tekla Perry writes on IEEE Spectrum.

Tabbara describes Symform’s approach as a “decentralized, distributed, virtual, and crowd-sourced” cloud. .… read more

Higher education is at a crossroads not seen since the introduction of the printing press, said MIT president L. Rafael Reif* in The Wall Street Journal.

“Residential education’s long-simmering financial problem is reaching a crisis point,” he said. “At the Massachusetts Institute of Technology and other campuses, the upheaval today is coming from the technological change posed by… read more

What Are We Thinking When We (Try to) Solve Problems?

January 30, 2008

Researchers have monitored the brain activity of volunteers tackling verbal problems to uncover what goes through the mind–literally–when the brain has an “aha!” moment of problem solving.

The singularity of a black hole

Now you can see what an epic journey through a tunnel in space-time might look like, thanks to an animation by astrophysicist Andrew Hamilton from University of Colorado at Boulder.

First, you free fall through the outer horizon of a black hole. Once you reach its inner horizon, you see an infinitely-energetic flash of light from the outside world containing an image of the entire… read more

Whales boast the brain cells that ‘make us human’

November 28, 2006

Whales have spindle neurons — specialised brain cells that are involved in processing emotions and helping us interact socially.

The cells occur in parts of the human brain that are thought to be responsible for our social organization, empathy, speech, intuition about the feelings of others, and rapid “gut” reactions.

What is more, whales appear to have had these cells for at least twice as long as humans,… read more

‘Wet’ computer server could cut wasted energy for cooling

February 27, 2013

iceotope_leeds

A revolutionary liquid-cooled computer server design that could slash the carbon footprint of the Internet is being tested at the University of Leeds.

Unlike most computers, which use air to cool their electronics, all of the components in the new server are completely immersed in liquid. The power-hungry fans of traditional computing are replaced by a silent liquid-cooling process that relies on the natural convection… read more

Western diets turn on fat genes

December 1, 2009

A diet high in fat and sugar switches on genes that ultimately cause our bodies to store too much fat, adding to the already difficult task of converting high-fat and high-sugar foods to energy, according to a study published online in the Federation of American Societies for Experimental Biology Journal.

West Antarctic Ice Sheet collapse is underway

ThwaitesShelf

Antarctica’s fast-moving Thwaites Glacier will likely disappear in a matter of centuries, potentially raising sea level by more than a half-a-meter (two feet), National Science Foundation-funded researchers at the University of Washington have concluded

Data gathered by NSF-funded airborne radar, detailed topography maps, and computer modeling were used to make the determination.

The glacier acts as an ice dam, stabilizing and regulating movement toward the sea… read more

Amid a worldwide boom in unmanned aerial vehicles (UAVs), a handful of U.S. colleges have begun offering classes and even four-year degrees for students looking for jobs in this fast-growing field, where even newcomers can earn six-figure salaries, The Daily reports.

Starting salaries for drone pilots range from $50,000 to $120,000 per year, said Tom Kenville, who founded a trade group called Unmanned Applications Institute International for development… read more

We’re underestimating the risk of human extinction

h-bomb

Unthinkable as it may be, humanity, every last person, could someday be wiped from the face of the Earth. We have learned to worry about asteroids and supervolcanoes, but the more-likely scenario, according to Nick Bostrom, a professor of philosophy at Oxford, is that we humans will destroy ourselves.

Most worrying to Bostrom is the subset of existential risks that arise from human technology, a subset that he expects… read more

We’re In Danger of Losing Our Memories

January 27, 2009

As the Internet evolves and technologies become obsolete, and with the continual loss of online records (like what happened at whitehouse.gov on Jan. 20, when all traces of George W. Bush disappeared), we are in danger of creating a black hole for future historians and writers unless urgent action is taken.

As chief executive of the British Library, it’s Lynne Brindley’s job to ensure that this does not extend… read more

‘We’re building a brain!’

April 5, 2002

Lobal Technologies of London is building a natural language processing system called LAD (Language Acquisition Device) that understands sentences word by word and builds its replies word-by-word, rather than just reading a script.The system is based on a model of the human brain, with emulators for the five brain areas that are most important for language processing, built using neural network technology

Lobal’s roadmap for developing LAD is based… read more

We’re all living longer, but longevity increases not benefitting everybody

Life_expectancy

Global lifespans have risen dramatically in the past 40 years, but the increased life expectancy is not benefitting body equally, say University of Toronto researchers. In particular, adult males from low- and middle-income countries are losing ground.

People are living longer on average than they were in 1970, and those extra years of life are being achieved at lower cost, the researchers, led by U of… read more

WellPoint and IBM to use Watson to improve health care

IBMWatson

IBM and health insurer WellPoint have teamed up to develop and launch Watson-based solutions to help improve patient care through the delivery of up-to-date, evidence-based health care. They plan to start in early 2012, working with select physician groups in clinical pilots.

For physicians, incorporating hundreds of thousands of articles into practice and applying them to patient… read more
