Edge.com - DREAM-LOGIC, THE INTERNET AND ARTIFICIAL THOUGHT By David Gelernter

What does it mean to think? Can machines think, or only humans? These questions have obsessed computer science since the 1950s, and grow more important every day as the internet canopy closes over our heads, leaving us in the pregnant half-light of the cybersphere. Taken as a whole, the net is a startlingly complex collection of computers (like brain cells) that are densely interconnected (as brain cells are). And the net grows at many million points simultaneously, like a living (or more-than-living?) organism. It's only natural to wonder whether the internet will one day start to think for itself.

(Or is it thinking already?)

These questions are important not only to the internet but to each individual computer. Computers grow more powerful all the time. Today, programs that are guided not just by calculations but by good guesses are important throughout the software landscape. They are examples of applied artificial intelligence — and the ultimate goal of artificial intelligence is to build a mind out of software, a thinking computer — a machine with human-like (or super-human) intelligence.

In a way these possibilities are frightening, or at least thought-provoking. But after all, human intelligence is the most valuable stuff in the cosmos, and we are always running short. A computer-created increase in the world-wide intelligence supply would be welcome, to say the least.

Big Bang Goes Bye Bye?

>> Friday, July 30, 2010

Technology Review - 7.27.10

A new cosmology successfully explains the accelerating expansion of the universe without dark energy; but only if the universe has no beginning and no end.

As one of the few astrophysical events that most people are familiar with, the Big Bang has a special place in our culture. And while there is scientific consensus that it is the best explanation for the origin of the Universe, the debate is far from closed. However, it's hard to find alternative models of the Universe without a beginning that are genuinely compelling.

That could change now with the fascinating work of Wun-Yi Shu at the National Tsing Hua University in Taiwan. Shu has developed an innovative new description of the Universe in which the roles of time space and mass are related in new kind of relativity.

Time Travel - Evading the "Grandfather Paradox"

>> Wednesday, July 28, 2010

ScienceNews - 7.20.10 by Laura Sanders


Novelists and screenwriters know that time travel can be accomplished in all sorts of ways: a supercharged DeLorean, Hermione’s small watch and, most recently, a spacetime-bending hot tub have allowed fictional heroes to jump between past and future.

But physicists know that time travel is more than just a compelling plot device — it’s a serious prediction of Einstein’s general relativity equations. In a new study posted online July 15, researchers led by Seth Lloyd at MIT analyze how some of the quirks and peculiarities of real-life time travel might play out. This particular kind of time travel evades some of its most paradoxical predictions, Lloyd says.

Any theory of time travel has to confront the devastating “grandfather paradox,” in which a traveler jumps back in time and kills his grandfather, which prevents his own existence, which then prevents the murder in the first place, and so on.

Even sharks are texting now

POPSCI - 7.21.10 by Justin McLachlan

When Animals Attack Australian researchers use satellite-linked buoys and seafloor sensors to track RFID-tagged great white sharks. Stephen Frink/Getty images.
Great white sharks have been around for more than four million years, yet they remain one of the world’s most mysterious animals. Scientists know that the beasts have special organs for sensing electromagnetic fields and that their jaws can snap down with 4,000 pounds of force. But migration patterns, which are critical for conservation efforts, are mostly unknown.
That will change now that marine biologists in Australia can follow the whereabouts of 75 of the man-eaters using radio-transmitter tags and a network of 20 satellite-linked buoys.

It’s not known how far great whites—whose worldwide numbers are estimated to be fewer than 3,500—migrate or if there’s a season when they spend more time near the coast, says Rory McAuley, a senior research scientist with Western Australia’s Department of Fisheries. McAuley hopes that the buoys, along with about 50 sensors on the ocean floor, will also reveal behavior. This information could help authorities better predict the monthly risk at beaches and restrict seasonal shipping routes to protect sharks from boats.

LiveScience - 7.23.10 by LiveScience Staff

Hitting the gym every day might do little to decrease your risk of death if you spend the rest of your time sitting down, a new study suggests.

The results show the time people spend on their derrieres is associated with an increased risk of mortality, regardless of their physical activity level.

The findings suggest public health messages should promote both physical activity and less time on the couch, the researchers say.

Internet running out of addresses

>> Friday, July 23, 2010

ReadWriteWeb - 7.21.10 by Richard MacManus

The Internet will run out of Internet addresses in about 1 year's time, we were told today by John Curran, President and CEO of the American Registry for Internet Numbers (ARIN). The same thing was also stated recently by Vint Cerf, Google's Chief Internet Evangelist.

The main reason for the concern? There's an explosion of data about to happen to the Web - thanks largely to sensor data, smart grids, RFID and other Internet of Things data. Other reasons include the increase in mobile devices connecting to the Internet and the annual growth in user-generated content on the Web.

Singularity Summit 2010 Announced

>> Tuesday, July 20, 2010

The Singularity Summit 2010 in San Francisco to Discuss Intelligence Augmentation

"Will it be one day become possible to boost human intelligence using brain implants, or create an artificial intelligence smarter than Einstein? In a 1993 paper presented to NASA, science fiction author and mathematician Vernor Vinge called such a hypothetical event a "Singularity", saying "From the human point of view this change will be a throwing away of all the previous rules, perhaps in the blink of an eye". Vinge pointed out that intelligence enhancement could lead to "closing the loop" between intelligence and technology, creating a positive feedback effect.

This August 14-15, hundreds of AI researchers, robotics experts, philosophers, entrepreneurs, scientists, and interested laypeople will converge in San Francisco to address the Singularity and related issues at the only conference on the topic, the Singularity Summit. Experts in fields including animal intelligence, artificial intelligence, brain-computer interfacing, tissue regeneration, medical ethics, computational neurobiology, augmented reality, and more will share their latest research and explore its implications for the future of humanity.

“This year, the conference shifts to a focus on neuroscience, bioscience, cognitive enhancement, and other explorations of what Vernor Vinge called ‘intelligence amplification’ (IA) — the other route to the Singularity,” said Michael Vassar, president of the Singularity Institute, which is hosting the event.

Irene Pepperberg, author of “Alex & Me,” who has pushed the frontier of animal intelligence with her research on African Gray Parrots, will explore the ethical and practical implications of non-human intelligence enhancement and of the creation of new intelligent life less powerful than ourselves. Futurist-inventor Ray Kurzweil will discuss reverse-engineering the brain and his forthcoming book, How the Mind Works and How to Build One. Allan Synder, Director, Centre for the Mind at the University of Sydney, will explore the use of transcranial magnetic stimulation for the enhancement of narrow cognitive abilities. Joe Tsien will talk about the smarter rats and mice that he created by tuning the molecular substrate of the brain’s learning mechanism. Steve Mann, “the world’s first cyborg,” will demonstrate his latest geek-chic inventions: wearable computers now used by almost 100,000 people.

Other speakers will include magician-skeptic and MacArthur Genius Award winner James Randi; Gregory Stock (Redesigning Humans), former Director of the Program on Medicine, Technology, and Society at UCLA’s School of Public Health; Terry Sejnowski, Professor and Laboratory Head, Salk Institute Computational Neurobiology Laboratory, who believes we are just ten years away from being able to upload ourselves; Ellen Heber-Katz, Professor, Molecular and Cellular Oncogenesis Program at The Wistar Institute, who is investigating the molecular basis of wound regeneration in mutant mice, which can regenerate limbs, hearts, and spinal cords; Anita Goel, MD, physicist, and CEO of nanotechnology company Nanobiosym; and David Hanson, Founder & CEO, Hanson Robotics, who is creating the world’s most realistic humanoid robots.

Harvard Business Review - 7.15.10 by Alexandra Samuel

#thankyoujesus for irl and online friends. Couldn't live w/o either.

Laptop down. It's IRL Face Time!

it was so cool meeting you irl! :)


IRL: In Real Life. It's used as shorthand all over the Internet, to distinguish what happens online from what happens offline.

And it's a lie.

If we still refer to the offline world as "real life," it's only a sign of deep denial — or unwarranted shame — about what reality looks like in the 21st century.

The race is on for handheld personal assistants

Technology Review - 7.16.10 by Erica Naone

Smart phones promise a lot of computing power and connectivity: We can search the Web and communicate from anywhere. But it can be hard to make full use of all these capabilities on small screens with tiny buttons. Now comes a new wave of applications that combine speech recognition and artificial intelligence to help people carry out simple tasks on their mobile devices.

The latest such service, from Vlingo, a company that makes voice-recognition applications, tries to go beyond earlier apps by combining a user's spoken commands with personal data and information stored online. Called "SuperDialer," the service can, for example, let a user say "Call pizza" and subsequently see a list of nearby pizza places drawn from both the user's address book and the Web.

British scientists claim to have solved one of the great mysteries of life, the universe, and everything in it: The chicken came before the egg, they say, and they're not mincing words.

"It had long been suspected that the egg came first, but now we have the scientific proof that shows that in fact the chicken came first," Sheffield University's Colin Freeman, according to a report in the Metro.

Researchers from Scotland and England used a supercomputer called HECToR to look in such detail at a chicken eggshell that they were able to determine the vital role of a protein used to kick-start the egg's formation.

Will the elusive Higgs be soon exposed to view?

>> Monday, July 12, 2010

NewScientist - 7.9.10 by Rachel Courtland

Could the unexpected results point to Higgs? (Image: Fermilab).

Could the elusive Higgs boson finally be in sight? On his blog, physicist Tommaso Dorigo of the University of Padua writes about talk of a tentative hint of the Higgs at the Tevatron, a particle accelerator at the Fermi National Accelerator Laboratory in Batavia, Illinois.

"It reached my ear, from two different, possibly independent sources, that an experiment at the Tevatron is about to release some evidence of a light Higgs boson signal. Some say a three-sigma effect, others do not make explicit claims but talk of a unexpected result," writes Dorigo.

The blog post is low on detail but if the "three-sigma" signature - a reference to the statistical certainty of the rumoured result - turns out to be real, it will be an immense discovery.

PhysOrg.com - 7.11.10

An image released by the ESA shows the Lutetia asteroid at closest approach from the Rosetta spacecraft. The European spacecraft Rosetta performed a fly-by of a massive asteroid on Saturday, the European Space Agency said, taking images that could one day help Earth defend itself from destruction.

The European spacecraft Rosetta performed a fly-by of a massive asteroid, the European Space Agency said, taking images that could one day help Earth defend itself from destruction.


Racing through the asteroid belt between Mars and Jupiter at 47,800 kph (29,925 mph), the billion-euro (1.25-billion-dollar) probe flew Saturday within 3,200 kms (2,000 miles) of the huge potato-shaped rock, Lutetia.

"The fly-by has been a spectacular success with Rosetta performing fautlessly," ESA said in a statement.

"Just 24 hours ago, Lutetia was a distant stranger. Now, thanks to Rosetta, it has become a close friend," the agency added.

Holger Sierks of Germany's Max Planck Institute, who is in charge of the spacecraft's Osiris (Optical, Spectroscopic and Infrared Remote Imaging System) camera said the more than 400 "phantastic images" showed many craters and details.

Taking God With You - How handheld tech is changing worship

>> Saturday, July 10, 2010

Live Science - 7.7.10 by Stuart Fox

From the printing press to the radio to the Internet, advances in communication technology have almost always instigated rapid and profound changes in religious practice. The proliferation of mobile devices like the iPhone is currently provoking a similarly profound change, simultaneously allowing worshippers to craft a personal religious environment in an otherwise secular world, but also diluting many practices central to all religions.

Already, hundreds of iPhone apps allow parishioners to bring Bible quotes, Torah-chanting practice and Buddhist prayer wheels wherever they go, allowing them to practice their religions in new times and spaces.

But some religious leaders worry that the inherently isolating and attention-diverting nature of smart phones has created a generation of worshippers unable to fully engage with the sublimation of self and quiet meditation that underlie both the Eastern and Western religious traditions.

Didn't we already know this? (New feature!)

I've decided to try a new feature here called, "Didn't we already know this?"

Scientific studies are great, but too often the results just confirm what we already knew from experience. Perhaps the study will prove to be helpful, but the titles make me want to scratch my head in wonder at the things we'll spend time, money and energy to prove.

Extreme-scale computing - approaching one quintillion calculations per second

>> Saturday, July 03, 2010

NetworkWorld - 6.23.10 by Michael Cooney

Not known for taking the demure route, researchers at DARPA this week announced a program aimed at building computers that exceed current peta-scale computers to achieve the mind-altering speed of one quintillion (1,000,000,000,000,000,000) calculations per second.

Dubbed extreme scale computing, such machines are needed DARPA says to "meet the relentlessly increasing demands for greater performance, higher energy efficiency, ease of programmability, system dependability and security." 

10 hot energy projects that could electrify the world

DARPA says its Omnipresent High Performance Computing (OHPC) systems will involve all manner of new research and development.  Specifically the outfit is looking for:

    * Hardware, software and algorithms for reducing and managing power requirements for high performance computing systems, including the memory and storage hierarchy


    * Hardware, software and language design that enables highly programmable systems, which reduces the need for users to be aware of system complexity, including heterogeneous cores, the memory hierarchy


    * Improved hardware and software for bolster system dependability, managing the component failure rate, and security compromises including approaches for shared information and responsibility among the OS, runtime system, and applications


    * Scalable I/O systems, which may include alternatives to file systems


    * Self aware system software, including operating system, runtime system, I/O system, system management/administration, resource management and means of exposing resources, and external environments

Inside Your Head - Who's really in charge?

>> Friday, July 02, 2010

Time - 7.27.10 by Eben Harrell

Laughing Stock / Corbis

Studies have found that upon entering an office, people behave more competitively when they see a sharp leather briefcase on the desk, they talk more softly when there is a picture of a library on the wall, and they keep their desk tidier when there is a vague scent of cleaning agent in the air. But none of them are consciously aware of the influence of their environment.

There may be few things more fundamental to human identity than the belief that people are rational individuals whose behavior is determined by conscious choices. But recently psychologists have compiled an impressive body of research that shows how deeply our decisions and behavior are influenced by unconscious thought, and how greatly those thoughts are swayed by stimuli beyond our immediate comprehension.

First ever direct photo of alien planet!

>> Thursday, July 01, 2010

Space.com - 6.29.10 by Denise Chow

A planet outside of our solar system, said to be the first ever directly photographed by telescopes on Earth, has been officially confirmed to be orbiting a sun-like star, according to follow-up observations.

The alien planet is eight times the mass of Jupiter and orbits at an unusually great distance from its host star — more than 300 times farther from the star than our Earth is from the sun.

Astronomers first discovered the planet in 2008 using visible light observations from telescopes on Earth, making it the first direct photo of an extrasolar world. But at the time there was still the remote chance that it only looked like it was orbiting the star, from the perspective of Earth, due to a lucky alignment of object, star and observer.
