The emergence of individuality in genetically identical mice

May 13, 2013

Enrichment enclosure housing 40 mice

How do people and other organisms evolve into individuals that are distinguished from others by their own personal brain structure and behavior?

Why do identical twins not resemble each other perfectly even when they grew up together?

To shed light on these questions, the scientists observed 40 genetically identical mice that were kept in an enclosure that offered a rich shared environment with a large variety of activity… read more

Samsung Electronics Co. said Sunday that it has successfully developed fifth-generation network (5G) core technology for the first time, allowing users to access faster data services expected to be available by 2020, Yonhap News Agency reports.

Under the new platform, users will be able to download and upload data at speeds of up to tens of gigabits per second (Gbps), compared to 75 megabits per second (Mbps)… read more

Bitcoin network speed 8 times faster than top 500 supercomputers combined

May 13, 2013

bitcoin

The mining speed of the bitcoin network on bitcoinwatch.com passed 1 exaFLOPS (1,000 petaFLOPS) this week — more than 8* times the combined speed of the Top 500 supercomputers, according to The Genesis Block.

(FLOPS stands for FLoating-point Operations Per Second, and is frequently used as a standard to measure computer speed.)

However, that calculation was based on 2011 supercomputer data and it’s not… read more

Creating a sense of touch in a prosthetic hand

May 13, 2013

prosthetic sensing

Scientists have made tremendous advances toward building lifelike prosthetic limbs that move and function like the real thing.

But what’s missing is a sense of touch, so a patient knows how hard he or she is actually squeezing something, or exactly where the object is positioned relative to his or her hand.

“If you lose your somatosensory [body senses] system, it almost looks like your motor system is… read more

Can bonding with your virtual self alter your perceptions?

May 12, 2013

avatar_bonding

If you create and modify your own virtual reality avatars, could what happens to these alter egos influence how you perceive virtual environments?

Penn State researchers found this question relevant to designing more realistic and immersive virtual reality exercises and games. They assigned random avatars to one group of participants, but allowed another group to customize their own avatars.

When placed in a virtual environment with three hills… read more

Amazon is developing smartphone with 3D screen

May 10, 2013

emporer

Amazon.com Inc. is developing a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, The Wall Street Journal reports.

Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, and users may be able to navigate through content using just their eyes, according to sources,

With smartphones, Amazon could collect new… read more

First biological signature of a supernova

May 10, 2013

Researchers at the Technical University of Munich have found a radioactive iron isotope in bacteria microfossils.that they trace back to a supernova in our cosmic neighborhood.

This is the first proven biological signature of a starburst on our earth. The age determination of the deep-drill core from the Pacific Ocean showed that the supernova explosion must have occurred about 2.2 million years ago, roughly around the… read more

US State Dept. orders removal of 3D-printed gun designs

May 10, 2013

liberator_1

The U.S. State Department has demanded designs by Defense Distributed for a 3D-printed gun be taken offline because publishing them online may breach arms-control regulations, Forbes reports.

The order to remove the blueprints for the plastic gun comes after they were downloaded more than 100,000 times.

However, the files were actually being served by Mega, the New Zealand-based storage service created by ex-hacker entrepreneur Kim… read more

Real-time brain feedback can help people overcome anxiety

May 10, 2013

This image from the study shows changes in degree of connectivity in the feedback group. Increases are shown in red/yellow and decreases in blue/purple. Decreases in connectivity are seen in limbic areas, and increases are seen in prefrontal regions. (Credit: Yale University)

People provided with a real-time readout of activity in specific regions of their brains can learn to control that activity and lessen their anxiety, say Yale researchers.

They used functional magnetic resonance imaging (fMRI), to display the activity of the orbitofrontal cortex (a brain region just above the eyes) to subjects while they lay in a brain scanner.

Through a process of trial and… read more

Robots with sensitive arms for delicate assistive tasks

May 9, 2013

With the new control method, Kemp’s robots have performed numerous tasks, such as reaching through dense artificial foliage and a cinder block representative of environments that search-and-rescue robots can encounter.

For safety reasons, robot makers have avoided contact between the robot’s arm and the world.

Now Georgia Tech and Meka Robotics researchers have developed a control method that enables a robot’s arm to make contact with objects, people, and the rest of the robot while keeping forces low.

The method  works with compliant robotic joints and whole-arm tactile sensing, and keeps the robot’s arm flexible,… read more

In his role as Google’s chief internet evangelist, Cerf has spent much of his time thinking about the future of the computer networks that connect us all.

Working with NASA and JPL, Cerf has helped develop a new set of protocols that can stand up to the unique environment of space, where orbital mechanics and the speed of light make traditional networking extremely difficult. Though this space-based… read more

The man behind the Google brain: Andrew Ng and the quest for the new AI

May 9, 2013

Artificial.intelligence

There’s a theory that human intelligence stems from a single algorithm.

The idea arises from experiments suggesting that the portion of your brain dedicated to processing sound from your ears could also handle sight for your eyes. This is possible only while your brain is in the earliest stages of development, but it implies that the brain is — at its core — a general-purpose machine that can be tuned… read more
