Neuroscientists plant false memories in the brain

MIT study also pinpoints where the brain stores memory traces, both false and authentic
July 26, 2013

The phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction.

In a step toward understanding how these faulty memories arise, MIT neuroscientists have shown that they can plant false memories in the brains of mice.

They also… read more

Lab-grown model 3D brains

"Cerebral organoids” can model complex human brain disorders and the earliest stages of brain development
August 30, 2013

organoid

Scientists in an Austrian laboratory have developed complex human brain tissue made from stem cells in a laboratory 3D culture system for the first time. The method allows induced pluripotent stem (iPS) cells (which have the potential to differentiate into almost any cell in the body) to develop into “cerebral organoids” — or “mini brains.”

These mini brains, which are a few millimeters across, develop several… read more

Elon Musk has released a video demonstrating SpaceX’s new custom 3D design interface, inspired by Iron Man.

It includes use of Leap Motion control, free-standing glass projections (from Iron Man), 3D projections using glasses, and the Occulus Rift VR headset.

After generating and manipulating the 3D model, Musk then 3D-prints an actual titanium metallic rocket-engine part from the model.

Human v 2.0: Ray Kurzweil vs. Hugo de Garis

October 24, 2006

“Meet the scientific prophets who claim we are on the verge of creating a new type of human – a human v2.0.

“It’s predicted that by 2029 computer intelligence will equal the power of the human brain. Some believe this will revolutionise humanity – we will be able to download our minds to computers extending our lives indefinitely. Others fear this will lead to oblivion by giving rise to… read more

Paging Dr. Watson: artificial intelligence as a prescription for health care

“It’s not humanly possible to practice the best possible medicine. We need machines,” said Herbert Chase, a professor of clinical medicine at Columbia University and member of IBM’s Watson Healthcare Advisory Board, Wired Science reports.

“A machine like [IBM's Watson], with massively parallel processing, is like 500,000 of me sitting at Google and Pubmed, trying to find the right information.”

Yet though Watson is clearly a powerful tool,… read more

Carnegie Mellon computer searches web 24/7 to analyze images and teach itself common sense

NEIL program labels images, learns associations with minimal help from people

A computer program called the Never Ending Image Learner (NEIL) is now running 24 hours a day at Carnegie Mellon University, searching the Web for images, doing its best to understand them. And as it builds a growing visual database, it is gathering common sense on a massive scale.

NEIL leverages recent advances in computer vision that enable computer programs to identify and label objects in images,… read more

Amazon is developing smartphone with 3D screen

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

Warrior Web to augment soldiers’ endurance

DARPA‘s Warrior Web program seeks to create a soft, lightweight under-suit that would help reduce injuries and fatigue common for soldiers, who often carry 100-pound loads for extended periods over rough terrain.

DARPA envisions Warrior Web augmenting the work of soldiers’ own muscles to significantly boost endurance, carrying capacity and overall warfighter effectiveness — all while using no more than 100W of power.… read more

How unconscious processing improves decision-making

February 15, 2013

New brain imaging research from Carnegie Mellon University provides some of the first evidence showing how the brain unconsciously processes decision information in ways that lead to improved decision making. Published in the journal Social Cognitive and Affective Neuroscience, the study found that the brain regions responsible for making decisions continue to be active even when the conscious brain is distracted with a different task.

asteroid

NASA is mulling over a plan to build a robotic spacecraft to grab a small asteroid and place it in high lunar orbit, according to researchers with the Keck Institute for Space Studies in California.

The mission would cost about $2.6 billion and could be completed by the 2020s, New Scientist reports.

The Obama administration has said it also wants to send astronauts to a near-Earth asteroid. One… read more

Unexplained communication between brain hemispheres without corpus callosum

Ag CC

Could the brain be using electromagnetic fields to communicate between hemispheres — the electromagnetic field theory of consciousness proposed by Johnjoe McFadden (School of Biomedical and Life Sciences, University of Surrey)?

Neuroscientists at the California Institute of Technology (Caltech) have made a puzzling finding: people born without a corpus callosum (which links the two hemispheres of the brain)  — a condition called agenesis… read more

How easy would it be to monitor the movement of everyone on the street by a private citizen with a few hundred dollars to spare?

Brendan O’Connor, 27, bought some plastic boxes and stuffed them with a $25, credit-card size Raspberry Pi Model A computer and a few over-the-counter sensors, including Wi-Fi adapters, The New York Times reports.

He connected each of those boxes to a… read more
