Makerbot Replicator 2 review

September 20, 2012

make_replicator_2

The Makerbot Replicator 2, a second generation of MakerBot’s wildly popular Replicator 3D printer, is now faster, quieter, and more rigid than the original, Make reports.

The Replicator now sports a sleek modern look with an all-black sheet metal frame and PVC side panels that are removable, customizable, and allow for easy cleaning of any excess material.

A larger, more responsive LCD panel on the front… read more

European scientists have built the first atlas of white-matter microstructure in the human brain in a project called CONNECT (Consortium of neuroimagers for the non-invasive exploration of brain connectivity and tracts).

The new atlas combines 3D images from the MRI scans of 100 brains of volunteers. To achieve this, the scientists developed advanced diffusion… read more

Why 3D printing will go the way of virtual reality

The notion that 3D printing will on any reasonable time scale become a “mature” technology that can reproduce all the goods on which we rely is to engage in a complete denial of the complexities of modern manufacturing, unless you’d like everything made out of plastic, says Technology Review | Mim’s Bits blog.

Microsoft’s Cortana to battle Siri

Microsoft is preparing a Siri-like personal voice assistant based on Bing, code-named Cortana, for Windows Phone,  eWeek reports. (Cortana is a holographic AI construct that figures prominently in the Halo video game series.)

Like its Halo counterpart, Cortana “will be able to learn and adapt, thanks to machine-learning technology and the ‘Satori’ knowledge repository powering Bing,” according to ZDNet’s Mary Jane Foley.

Satori, which… read more

BioPen rewrites orthopedic implant surgery

Delivers live stem cells and growth factors at the time of surgery to regenerate bone, cartilage, muscle, or nerve tissue
December 13, 2013

biopen3

Australian researchers have developed a handheld “BioPen” that will allow surgeons to precisely design and deliver customized bone and other implant materials (live stem cells and growth factors) at the time of surgery to regenerate bone, cartilage, muscle, or nerve tissue.

Here’s how it works:

  1. Similar to a multi-material 3D printer, the BioPen delivers stem cells embedded in a biopolymer carrier (such as alginate, a seaweed extract), protected

An electric car that actually goes far?

July 20, 2012

electric_car_goes_far

Researchers have made the first stable lithium-air batteries, Science NOW reports. They may one day give electric cars a driving range similar to today’s gas guzzlers.

Lithium-air batteries have potential to store 10 times more energy than the best lithium-ion batteries on the market today, but have been unstable, falling apart after a few charges.

So researchers at the University of St Andrews in the United… read more

Human brains share a consistent genetic blueprint and possess enormous biochemical complexity

First extensive analysis of Allen Human Brain Atlas has implications for basic understanding of the human brain and for medicine

The same basic functional elements are used throughout the cortex and understanding how one area works in detail will uncover fundamentals that apply to the other areas as well, scientists at the Allen Institute for Brain Science reported in the latest issue of the journal Nature.

Human brains share a consistent genetic blueprint, and possess enormous biochemical complexity, they said, based on the first deep and large-scale… read more

Physicists create synthetic magnetic monopoles

May lead to entirely new materials, such as superconductors
January 30, 2014

Nearly 85 years after pioneering theoretical physicist Paul Dirac predicted the possibility of their existence, scientists have created, identified and photographed synthetic magnetic monopoles.

The groundbreaking accomplishment, described by a paper in Nature, paves the way for the detection of the particles in nature, which would be a revolutionary development comparable to the discovery of the electron, according to the scientists.

“The creation of a synthetic magnetic monopole… read more

An Earth-like exoplanet in mass and size discovered

October 31, 2013

Gliese436b

MIT researchers have found that Kepler 78b, a small, intensely hot planet 400 light-years from Earth discovered by the researchers in August, shares Earth’s mass.

By analyzing the movement of its host star, Kepler 78, the scientists determined that the exoplanet is about 1.7 times as massive as the Earth.

From the same measurements, they calculated that the planet’s density is 5.3 grams… read more

Are you ready for computers as comedians?

January 7, 2013

As verbal interaction between humans and computers becomes more prominent in daily life — from Siri, Apple’s voice-activated assistant technology, to speech-based search engines to fully automated call centers — demand has grown for “social computers” that can communicate with humans in a natural way.

Teaching computers to grapple with humor is a key part of this equation, author Alex Stone writes in The New York Times Sunday Review.… read more

Stephen Hawking: ‘There is no heaven; it’s a fairy story’

May 16, 2011

A belief that heaven or an afterlife awaits us is a “fairy story” for people afraid of death, Stephen Hawking has said.

“I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark,” he said.

In a lecture Monday at the Google Zeitgeist meeting… read more

An easy, low-cost way to get into 3D printing

January 7, 2014

MakerBot Mini

If you’ve been thinking about getting into 3D printing, the compact MakerBot Replicator Mini 3D printer, just introduced at CES, could make it easy and affordable at $1,375 (available spring 2014).

It’s limited to printing objects around 4 x 4 x 4 inches, but the company claims it’s easy to use, with no 3D skills needed. You can download models from the free MakerBot Printshop and Thingverse,… read more

Ultra-thin capacitors could acclerate development of next-gen electronics

Japanese researchers at the National Institute for Materials Science and Shinshu University have developed a way to shrink capacitors — key components that store energy — further, which could accelerate the development of more compact, high-performance next-gen electronic devices. The study appears in the journal ACS Nano.

Takayoshi Sasaki and colleagues note that current technology has almost reached its limit in terms of materials and processing, which in turn… read more

Cloud-computing ‘Internet for robots’ launched

March 11, 2013

RoboEarth_Grafik

Researchers of five European universities have developed the RoboEarth Cloud Engine, a cloud-computing platform for robots.

The platform allows robots connected to the Internet to directly access the powerful computational, storage, and communications infrastructure of modern data centers — the giant server farms behind the likes of Google, Facebook, and Amazon — for robotics tasks and robot learning.

The new platform extends earlier work… read more
