At the TED conference in Los Angeles, architect and computer scientist Skylar Tibbits showed how the process allows objects to self-assemble, BBC News reports.

It could be used to install objects in hard-to-reach places such as underground water pipes, he suggested.

It might also herald an age of self-assembling furniture, said experts.

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.

Blocking this molecule in the brain could prevent age-related cognitive decline

February 8, 2013

Researchers have discovered a molecule that accumulates with age and inhibits the formation of new neurons. The finding might help scientists design therapies to prevent age-related cognitive decline.

The investigators identified the molecule, called Dickkopf-1 or Dkk1, in the brains of aged mice. By blocking production of Dkk1, “we released a brake on neuronal birth, thereby resetting performance in spatial memory tasks back to levels observed in… read more

Astronaut on ISS uses interplanetary Internet to control robot in Germany

November 12, 2012

legorobot_esa

NASA and the European Space Agency (ESA) used an experimental version of interplanetary Internet in late October to control an educational rover from the International Space Station, NASA says.

The experiment used NASA’s Disruption Tolerant Networking (DTN) protocol to transmit messages and demonstrate technology that one day may enable Internet-like communications with space vehicles and support habitats or infrastructure on another planet.

University of Cambridge scientists have created a new type of microchip that allows information to travel in three dimensions, enabling additional storage capacity on chips.

Currently, microchips can only pass digital information in a very limited way — from either left to right or front to back, the researchers say.

In the future, a 3D microchip would enable additional storage capacity on chips by… 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

Touted as an eco-friendly floating city, the Seascraper  is among concepts for sustainable offshore settlements described by National Geographic.

“With more than seven billion people on the planet, mass migrations to cities, and increased risks of flooding and sea level rise, more and more architects and innovators seem to be weighing anchor,” NatGeo says.

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

A consortium of European researchers has developed a customizable robot companion for people with memory or mobility problems.

The robot, a mobile wheeled semi-humanoid figure equipped with cameras, sensors, audio and a touch screen interface, can remind users to take their medicine, suggest they have their favorite drink or prompt them to go for a walk or visit friends if they haven’t been out for a while,… read more

A Japan-developed robot for disaster response

Toshiba has developed a remote-controlled tetrapod inspection robot with camera and dosimeter, designed to investigate risky areas, such as Fukushima nuclear power plants.

The multiple joints of its legs are controlled by a movement algorithm that enables the robot to walk on uneven surfaces (like Boston Dynamics’ Big Dog), avoid obstacles, and climb stairs to get access into areas can’t be reached by wheeled robots (such as some iRobot… read more

MIT researchers build ultrahigh-definition Quad HD (4K) TV chip

February 21, 2013

At the International Solid-State Circuits Conference this week, MIT researchers unveiled their own Quad HD video chip design.

Quad HD is also known as 4K and ultrahigh-definition (UHD). The new Quad HD video standard enables a fourfold increase in the resolution of TV screens.

At the Consumer Electronics Show (CES) in January, several manufacturers debuted new UHD models.

There is no UHD content… read more

Beyond Second Life: more realistic avatars

May 21, 2013

Philip Rosedale, founder of once-popular virtual world Second Life, has created a new company called High Fidelity. As suggested by the video above and the blog, the company is developing more natural ways for avatars to communicate (with heads and hand movements, for example) and with low latency (faster response time).

“Imagine holding your phone and being able to twist and move your avatar’s hand.… read more

Elon Musk has decided that the next step for Tesla Motors cars is to go (mostly) autonomous, IEEE Spectrum reports.

From the Financial Times:
“We should be able to do 90 percent of miles driven within three years,” [Musk] said. Mr Musk would not reveal further details of Tesla’s autonomy project, but said it was “internal development” rather than technology being supplied by another company.read more
