In a new book, MIT’s Ethan Zuckerman asserts that we need to overcome the Internet’s sorting tendencies and create tools to make ourselves “digital cosmopolitans.”

The Internet promises a seemingly frictionless way of connecting individuals from around the globe. But in reality, that’s not what happens online: Instead, we clump together with people similar to ourselves, and have those affinities reinforced by tools that guide us… read more

Neuroscientists have developed a new brain electrode that is a millimeter long, only a few nanometers wide and harnesses the superior electromechanical properties of carbon nanotubes to capture electrical signals from individual neurons.

“To our knowledge, this is the first time scientists have used carbon nanotubes to record signals from individual neurons, what we call intracellular recordings, in brain slices or intact brains of vertebrates,” said Bruce… read more

The herbal extract of a yellow-flowered mountain plant long used for stress relief was found to increase the lifespan of fruit fly populations by an average of 24 percent, according to UC Irvine researchers.

But it’s how Rhodiola rosea, also known as golden root, did this that grabbed the attention of study leaders. They discovered that Rhodiola works in a manner completely unrelated to dietary restriction and… read more

For less than $100, University of Washington researchers have designed a computer-interfaced drawing pad that helps scientists see inside the brains of children with learning disabilities while they read and write.

A paper describing the tool, developed by the UW’s Center on Human Development and Disability, was published this spring in Sensors, an online open-access journal.

“Scientists needed a tool that allows them to see… read more

Scientists at Rice University and Oak Ridge National Laboratory (ORNL) have advanced on the goal of achieving two-dimensional electronics with a method to control the growth of uniform atomic layers of molybdenum disulfide (MDS).

MDS, a semiconductor, is one of three materials needed to make functioning 2D electronic components. The hope is that MDS could be joined with graphene, which has no band gap, and… read more

Air-ground fire coordination—also known as Close Air Support or CAS—is a dangerous and difficult business. Pilots and dismounted ground agents must ensure they hit only the intended target using just voice directions and, if they’re lucky, a common paper map.

It can often take up to an hour to confer, get in position and strike — time in which targets can attack first or move out of reach. To… read more

An algorithm developed in EPFL’s School of Computer and Communications Sciences makes it possible to measure the dimensions and shapes of a room using just four microphones and a snap of your fingers.

“Our software can build a 3D map of a simple, convex room with a precision of a few millimeters,” explains PhD student Ivan Dokmanić.

Given recent revelations of intrusive government surveillance, this 2006 essay raises fundamental questions worth considering.

Criminals vs. Terrorists

In an attempt to make David Brin’s [1] privacy-free “transparent society” more palatable to civil libertarians, Robert Sawyer [2] has proposed an “Alibi Archive” in which everyone’s activities are meticulously recorded in a centralized, judicially controlled archive, with the archives legally accessible only under court order and only upon… read more

Most people know Timothy Leary as the “LSD guru” who encouraged people to “Turn On, Tune In, Drop Out” in the 1960s. But a surprising number of transhumanist types don’t know that he was one of them.

In fact, Leary may have been the first to signal a memeplex for the transhuman future — SMI2LE (Space Migration Intelligence Increase and Life Extension) — back in the mid-1970s.

Dear Mr. Raymond Kurzweil, hello,

How are you? My name is Noga, I’m a 16-year-old girl from Tel-Aviv, Israel.

First of all, I wanted to say that I’ve read one of your and it was fascinating. Secondly, I wanted to ask you a question. I’ll start from the beginning.

In my school, we have a course called “Human Rights.” It’s a course where we discuss many things… read more

Dear Ray:

If the development of computer-based intelligence will become equivalent to that of human intelligence within the next twenty or thirty years, this computer-based intelligence will be able to build even better computers.

Such computer intelligence will, no doubt, find a way to enhance the thought process of the human mind.

No doubt it will supersede the capacity of the human mind. This leads me to… read more

Hi, my name is Luke.

I’m contacting you now and asking you to please consider the following scenario. AD 2060 or later:

Humans can simulate multiple universes. We do so, and eventually intelligent life evolves in one and achieves a civilization with roughly the same science and computation as Earth 2010. This life will be a completely alien species, on a (simulated) alien planet.

That species figures… read more

Dan Brown’s latest action thriller Inferno follows art historian Robert Langdon in a fast-paced roller-coaster hunt for the source of a genetic hack delivered to everyone on the planet via a highly contagious airborne virus.

In Dan Brown’s Inferno [see book review | Dan Brown’s Inferno], an airborne virus permanently modifies the DNA in human cells in one third of the population of the world.

We asked synthetic biologist/genomic futurist Andrew Hessel to comment on this scenario (his co-authored “The Bio-Crime Prophecy” is the cover story in the current issue of Wired UK).

Q: How realistic is Brown’s… read more

Why can’t a robot be like a servant (to paraphrase My Fair Lady)? You know, one who would anticipate your every need — even before you asked?

The folks at the Personal Robotics Lab of Ashutosh Saxena, Cornell assistant professor of computer science have gone and done just that.

When we last (virtually) visited the lab, we learned that the roboticists taught  “hallucinating” robots to arrange your room… read more

A recent article in EE Times discusses the future of Moore’s law: “Broadcom: Time to prepare for the end of Moore’s Law.” This comes up innumerable times. People assume that Moore’s law is synonymous with my law of accelerating returns, which it is not.

Moore’s law was the fifth, not the first, paradigm to bring exponential growth to the price-performance of computing. The law of accelerating returns does… read more

The International Space Development Conference (ISDC), produced by the National Space Society (NSS) — the happening place to learn about the future of space — kicks off Thursday May 23 and runs through Monday May 27 at the Hyatt Regency La Jolla in San Diego, California. ISDC speakers will discuss a wide range of breakthroughs in space development. Here are just two that I find especially interesting. (Full… read more

Zoltan Istvan’s The Transhumanist Wager is an epic story of radical libertarian ideas, their enemies, and the violent global conflict that ensues, painted in strong saturated colors with little room for intermediate shades and character development.

After reading cover to cover, and then reading it more carefully, I have mixed love/hate feelings about this novel.

It’s a page turner. Istvan — a former journalist… read more

This is a really interesting article about body and mind which I recently read. I wanted to share it with my readers:

The New York Times | “I am not this body”

“My body and I have an intimate but awkward relationship, like foreign roommates who share… read more

“Where’s my flying car?”

Skeptics have trashed predictions of flying cars with this annoying question ever since the Jetsons.

But now Terrafugia Inc. has announced feasibility studies of a four-seat, vertical takeoff and landing (VTOL) [similar to a helicopter] plug-in hybrid-electric flying car, the TF-X.

Just tell it where to go. It flies (and lands) for you — no runway needed — and… read more
