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

Volvo Car Group’s “Drive Me” project — featuring 100 self-driving Volvos on public roads in everyday driving conditions — is moving forward rapidly, with the first test cars now driving around the Swedish city of Gothenburg.

“The test cars are now able to handle lane following, speed adaption, and merging traffic all by themselves,” says Erik Coelingh, Technical Specialist at Volvo Car Group.

“This is an important step… read more

MIT researchers have devised computational solutions to reduce the chances that Amazon’s planned delivery drones will crash and burn — along with your stuff.

It’s complicated. Drones have to deal with iffy factors like high winds, low fuel/power level, component failures, and even possible shooters in some locations.

So with Boeing support, the researchers developed two fixes.

  • An algorithm enables a drone to monitor aspects of

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

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.

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

uhd_quadhd_mit

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

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

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

Simulated attack on the US power grid planned for Wednesday — Thursday
