LONDON, England (CNN) — Over the past 20 years, robotics have revolutionized surgery, and new innovations are continuing to push the boundaries of medicine.
Mike Rustic, senior lecturer at the mechanical engineering department at Imperial College, London, says machines such as the “da Vinci” system have had a huge impact on surgery.
The “da Vinci” first appeared in 1991 and lets surgeons carry out keyhole surgery remotely, allowing them to control robot arms from a console that also provides a three-dimensional image of the proceedings.
While the “da Vinci” …

(WIRED) — Scientists are one step closer to knowing what you’ve seen by reading your mind.
Having modeled how images are represented in the brain, the researchers translated recorded patterns of neural activity into pictures of what test subjects had seen.
Though practical applications are decades away, the research could someday lead to dream-readers and thought-controlled computers.
“It’s what you would actually use if you were going to build a functional brain-reading device,” said Jack Gallant, a University of California, Berkeley neuroscientist.
The research, led by Gallant and Berkeley postdoctoral researcher …

Forgot to charge your cell phone last night? Imagine that you could power it by walking. Weirder still, you might be able to just spray a new battery on.
These concepts are being developed by two leading nanotechnology researchers who are developing cleaner, more efficient ways of delivering electrical power. In working toward making these ideas realities, they are making use of structures that are 100 nanometers or smaller, where one nanometer is a billionth of a meter.
“[The nanoscale] can make the components small, sensitive and high-performance,” said Zhong Lin …

Mobile providers have said that US proposals to ensure all traffic on the internet is treated equally should not be applied to wireless traffic.
The Federal Communications Commission (FCC) wants rules to prevent providers blocking or slowing down bandwidth-heavy usage such as streaming video.
Providers claim a two-tiered system is essential for the future vitality of the net.
Mobile operators said any regulation would damage innovation.
FCC chairman Julius Genachowski said doing nothing was not an option.
In his first major speech since his appointment earlier in the summer, he told an …

When is a cyber-attack a real one?
AMERICA and other countries still have to fine-tune their cyber-defences to distinguish mere nuisances from real menaces. That, rather than any revelations about fiendish North Korean cyber-warfare, seems to be the upshot of the latest reported cyber-attack on South Korean and American websites.
Initially, it was reported that this was the first series of attacks to hit government websites in several countries simultaneously. Officials in both Seoul and Washington, DC, said they were suffering “distributed denial of service” overload (known as DDOS in geekspeak). In …

ISLAMABAD: Despite the fact that dumping old computers in developing countries has been declared as violation of international law, Pakistan was being used as dumping ground for over 50,000 tons of e-waste that hurts local industry and also creates environmental and health hazards.
Despite being a signatory to the Basel Convention that restricted importing used/old computers, more than 500,000 used computers are finding ways into Pakistani computer market each year.
These concerns were voiced at a discussion ‘Cost effective or technology defective’ held here on Tuesday.
The speakers from both public and private …

Open-source software firms are flourishing, but are also becoming less distinctive
MANY technology firms are floundering amid the recession. But many of the ones that offer services tied to open-source software—free programs written by volunteers who collaborate online—are boasting double-digit growth. Sales at Red Hat, the world’s biggest independent open-source firm with annual revenues of $653m, grew by 18% year-on-year in the first quarter. More and more firms, particularly in Europe, seem prepared to embrace open source (see chart). “Budgets are tight and we think that is good for open source,” …

This Islamic country, located in the mountainous region neighboring to the Central Asia and the Middle East, is the sixth most populous country in the world and has the second largest Muslim population in the world after Indonesia. That is Pakistan. The country is listed among the “Next Eleven” economies that means it’s among eleven countries, such as Bangladesh, Egypt, Indonesia, Iran, Mexico, Nigeria, Pakistan, The Philippines, South Korea, Turkey, and Vietnam, identified by Goldman Sachs investment bank as having a high potential of becoming the world’s largest economies in …

A disc that can store 500 gigabytes (GB) of data, equivalent to 100 DVDs, has been unveiled by General Electric.
The micro-holographic disc, which is the same size as existing DVD discs, is aimed at the archive industry.
But the company believes it can eventually be used in the consumer market place and home players.
Blu-ray discs, which are used to store high definition movies and games, can currently hold between 25GB and 50GB.
Micro-holographic discs can store more data than DVDs or Blu-ray because they store information on the disc in three dimensions, …

The computer company that has in the past taken on the grandmasters of chess is now turning its attention to the famed US trivia quiz show Jeopardy.
In a head-to-head challenge of man versus machine, IBM will pit a supercomputer named Watson against human contestants.
Watson is a new question-answering system based on natural language.
“The aim is to get Watson to think and interact in human terms,” IBM’s Dr David Ferrucci told BBC News.
“It will try to understand a user’s question and …
