Reflections on Stephen Wolfram’s A New Kind of Science

May 13, 2002 by Ray Kurzweil

A New Kind of Science

In his remarkable new book, Stephen Wolfram asserts that cellular automata operations underlie much of the real world. He even asserts that the entire Universe itself is a big cellular-automaton computer. But Ray Kurzweil challenges the ability of these ideas to fully explain the complexities of life, intelligence, and physical phenomena.… read more

What just happened? Why some of us seem totally spaced out

Ever wonder why uncle Louie seems to imagine stuff that didn’t happen, and calls you crazy? Well now’s there’s an explanation.

Half of you won’t like it, I warn you.

A new study of the brain by University of Cambridge scientists explains why some people can’t tell the difference between what they saw and what they imagined or were told about — such as whether they or another… read more

“We are creating systems of comprehensive surveillance in which a billion people are involved and those people’s lives are being lived under a kind of scrutiny which no secret police service is the 20th century could ever have aspired to achieve,” claims militant digital privacy advocate Eben Moglen, Betabeat reports.

“And all of that data is being collected and sold by people whose goal it is to… read more

Ask Ray | Study shows a 30% lower rate of breast cancer mortality with supplement use

December 30, 2013 by Terry Grossman

Breast Cancer Research and Treatment cover

Dear readers,

Here is a study coming out of the large and well respected Women’s Health Initiative showing positive results for supplements and breast cancer.

Unfortunately, the media has largely ignored it.

It seems there is a strong media bias to headline studies suggesting negative or no benefit results and to ignore positive ones that do show benefit. For example, this study shows a 30% lower rate… read more

Electronic hippocampal system turns long-term memory on and off, enhances cognition

June 17, 2011 by Amara D. Angelica

Can we reverse-engineer the brain, and eventually replace damaged portions of it with electronic devices? Research just announced suggests that’s a realistic idea.

In a major breakthrough in treating brain disorders, Theodore Berger and his team at the USC Viterbi School of Engineering’s Department of Biomedical Engineering, along with Wake Forest University researchers, have developed a neural prosthesis for rats that is able to restore their ability… read more

How to access TV news on any topic for the last three years

September 20, 2012 by Amara D. Angelica

This is fantastic news for journalists and voters: the Internet Archive has launched the free TV News Search & Borrow service.

The collection now contains 350,000 news programs collected over 3 years from national U.S. networks and stations in San Francisco and Washington D.C.  The archive is updated with new broadcasts 24 hours after they are aired.  Older materials are also being added.… read more

Beyond texting: augmented-reality windshields — what could go wrong?

January 16, 2012 by Amara D. Angelica

What? You thought distracted drivers texting on cell phones and swerving erratically is a problem? That’s so 2011.

Imagine a future in which icons flash on your car windshield, hologram-style, as your car approaches restaurants, stores, historic landmarks or the homes of friends, effuses CNN.

Simply point your hand at them, and the icons open to show real-time information: when that bridge over there was built,… read more

Getting ‘hallucinating’ robots to arrange your room for you

When we last (virtually) visited the Personal Robotics Lab of Ashutosh Saxena, Cornell assistant professor of computer science, we learned that they’ve taught robots to pick up after you, while you sit around and watch Futurama.

But why stop there in your search for the ultimate slave robot? Now they’ve taught robots where in a room you might stand, sit, or work,read more

When The Speed Of Light Is Too Slow: Trading at the Edge

November 11, 2010 by Thomas McCabe

optimaltradinglocations

Modern stock market trading computers have become so fast that the speed of light is now their key limiting factor. A new paper by a physicist and a mathematician explains how traders can take advantage of this ultimate speed limit.

Computers were originally introduced in trading because they are faster than us in responding to market signals. A human trader might buy up a million shares of Microsoft for… read more

I’ve seen the future of electronics and it’s … vacuum tubes!

July 12, 2012 by Amara D. Angelica

back_to_the_vacuum

Huh? Yep, you read it right.

We are bumping into a limit to increasing transistor speed, determined by the “electron transit time” — the time it takes an electron to travel, says Hong Koo Kim, a professor in the University of Pittsburgh’s Swanson School of Engineering.

It’s back to the vacuum, folks.

Kim explains: electrons traveling inside a semiconductor device frequently experience collisions or scattering… read more

Richard B. Hoover, Ph.D. NASA/Marshall Space Flight Center has discovered evidence of microfossils similar to terrestrial cyanobacteria in freshly fractured slices of the interior surfaces of two meteorites. He found that similar to trichomic cyanobacteria and other trichomic prokaryotes such as filamentous sulfur bacteria.

“The filaments have been observed to be embedded in freshly fractured internal surfaces of the stones,” said. “They exhibit features (eg, the size and size… read more

How to remote-control a robot on another planet

July 4, 2011 by Amara D. Angelica

Meet Justin, an android on Earth who will soon be controlled remotely by an astronaut in the European Space Agency’s Columbus laboratory on the International Space Station. The astronaut will don an exoskeleton to remotely control Justin.

The long-range goal: explore the Moon and planets with tele-operated robots.

How to learn things automatically

December 12, 2011 by Amara D. Angelica

Decoded Neurofeedback

OK, this one’s right out of The Matrix and The Manchurian Candidate.

Imagine watching a computer screen while lying down in a brain imaging machine and automatically learning how to play the guitar or lay up hoops like Shaq O’Neal, or even how to recuperate from a disease — without any conscious knowledge.

Researchers at Boston University (BU) and ATR Computational Neuroscience Laboratories in Kyoto, Japan… read more

A super-memory smart drug?

December 15, 2011 by Amara D. Angelica

Suppression of PKR

Could this be the “Limitless” breakthrough we’ve been looking for?

Researchers at Baylor College of Medicine  (BCM) have discovered that when the activity of PKR — a molecule normally elevated during viral infections — is inhibited in the brain, mice learn and remember dramatically better.

“The molecule PKR (the double-stranded RNA-activated protein kinase) was originally described as a sensor of viral infections,… read more

Virtual self

January 25, 2011

A still image of a Project LifeLike avatar conversing with a person. Project LifeLike is a collaboration between the Intelligent Systems Laboratory (ISL) at the University of Central Florida (UCF) and the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC) that aims to create visualizations of people, or avatars, that are as realistic as possible. While their current results are far from perfect replications of a specific person, their work has advanced the field forward and opens up a host of possible applications in the not-too-distant future.  (University of Chicago/University of Central Florida)

Your avatar may be just a virtual identity, but it can also affect how you are in the real world.

“In this world of new media, people spend a lot of time interacting with digital versions of one another.” — Jeremy Bailenson

If you spend a lot of time online, you may even have an electronic alter ego–an avatar. An avatar is a movable image that people design… read more
