Vernor Vinge is optimistic about the collapse of civilization

March 22, 2012

Noted author and futurist Vernor Vinge is surprisingly optimistic when it comes to the prospect of civilization collapsing.

“I think that [civilization] coming back would actually be a very big surprise,” he says in this week’s episode of the Geek’s Guide to the Galaxy podcast. “The difference between us and us 10,000 years ago is … we know it can be done.”

But could humanity really claw its way back… read more

Verizon’s fiber race is on

July 20, 2004

Verizon Communications plans to debut a 30mbps broadband-over-fiber service called Fios to homes later this summer.

It will offer voice calls, video and broadband in competition with telephone and cable companies, initially in three cites.

A 2mbps to 5mbps Fios connection will cost $35 a month if purchased along with Verizon’s local and long-distance telephone service. A connection of up to 15mbps is available for $45 a month… read more

Verizon trumps Wi-Fi with 500 k/bits

January 9, 2004

Verizon is rolling out its “BroadbandAccess” (300 to 500 kbit/s, with with bursts of 2 Mbits/s) cell phone service nationwide this year.

Verizon promises its “iobi” service will offer features such as programmable call forwarding or voice mail showing up as email and much closer integration between landline, IP and cellular networks.

Verizon Goes Up & Down at 10 Gbps in Tests

October 27, 2010

Verizon said Tuesday it had conducted a successful trial of 10 gigabit per second connections on both the download side and on the upload side, pioneering a new technology called XG-PON to make such speeds happen.

Verizon is offering a platform that’s not only competitive to cable broadband for consumers, but will become a platform for innovation for businesses now operating in the “cloud.”

Venture for Sharing Wi-Fi Draws Big-Name Backers

February 6, 2006

A “global network of shared Wi-Fi connections” will allow users of Wi-Fi wireless technology to connect to the Internet at many physical locations, in contrast to the limited access available now.

The “Fon” network, backed by Google, Skype, and two venture-capital firms, is operating in Europe, and plans call for expanding it into the United States and other countries this year.

Venture Capitalists Want to Put Some Algae in Your Tank

March 7, 2007

United States venture capital flowing into clean energy leapfrogged to more than $2.4 billion in 2006, well more than double that invested in 2005, and more than triple from 2004.

The ascent of venture capital in renewable energy has reminded some Silicon Valley venture capitalists of the early flow of money into the Internet in the mid-1990s.

Venture capitalist: We need to prepare for artificial intelligence

September 7, 2007

Q: What do people most misunderstand about the idea of singularity?

A: I don’t think they understand how radically different the world will be in 30 or 40 years, and there are choices that we need to make today to shape the future. – Peter Thiel, a venture capitalist who co-founded PayPal and speaker at the Singularity Summit this weekend.

Venture Capital Rushes Into Alternative Energy

April 30, 2007

Money is flowing into alternative energy companies so fast that “the warning signs of a bubble are appearing,” according to a report on investment in clean technology by a New York research firm, Lux Research.

The report also suggests that companies that make equipment to cleanse air or water, or that process waste, have been overlooked by investors.

The initial public offerings were primarily in companies involved in… read more

Venter to Bio World: Exa-Byte Me

November 13, 2002

Craig Venter, delivering the opening address yesterday at the BioITWorld conference here, said that computer power will be the limiting factor in crunching, storing, and manipulating the data necessary for linking the promise of genomics to insights into gene function, protein interaction, and personalized medicine. To underscore his point, he said the Celera computers that sequenced the human genome – the 1.5 teraflop, 120 terabyte machines that took up 6,000… read more

Venter Takes Step Toward Synthetic Cells

July 3, 2007

Moving a step closer to making cells from scratch, a team at the J. Craig Venter Institute took all of the genes from one species of bacteria, Mycoplasma mycoides, and transferred them into another, Mycoplasma capricolum.

The result: The genes from the mycoides took over, changing the cells from one species to another simply by moving around DNA.

Researchers hope that custom-engineered cells could be useful in producing… read more

vCJD may lurk in more people than realised

May 22, 2006

The deadly human form of mad cow disease, vCJD, may have infected far more people than previously thought, suggests a new study in the British Medical Journal.

Variant Creutzfelt-Jakob disease is linked to eating meat infected with bovine spongiform encephalopathy (BSE), also known as mad-cow disease. A rogue version of a prion protein proliferates in the brain, leading to distressing mental deterioration, loss of motor control, and eventually death.

Vast Spy System Loots Computers in 103 Countries

A vast electronic spying operation has infiltrated computers and has stolen documents from hundreds of government and private offices around the world, University of Toronto researchers have found.

Vapor nanobubbles rapidly detect malaria through the skin

One portable device able to screen up to 200,000 people per year, operated by non-medical personnel
January 2, 2014

Rice University researchers have developed a noninvasive technology that accurately detects even a single malaria-infected cell among a million normal cells through the skin in seconds with a laser scanner.

The “vapor nanobubble” technology requires no dyes or diagnostic chemicals, there is no need to draw blood, and there are zero false-positive readings.

The diagnosis and screening will be supported by a low-cost, battery-powered portable device that… read more

Vanishing Gas Confirms Black Hole Event Horizons

A type of X-ray explosion found on neutron stars does not occur near black holes, scientists announced at the 207th meeting of the American Astronomical Society.

The lack of explosions is strong evidence for the existence of a black hole event horizon, a theoretical boundary into which matter vanishes and cannot escape.

“By looking at objects that pull in gas, we can infer whether that gas… read more
