‘Minority Report’ interface created for US military

April 18, 2005

A computer interface inspired by the futuristic system portrayed in the movie Minority Report could soon help real military personnel deal with information overload.

The system under development at Raytheon lets users don a pair of reflective gloves and manipulate images projected on a panoramic screen. A mounted camera keeps track of hand movements and a computer interprets gestures.

Raytheon plans to offer the technology as a way… read more

New Thoughts On Language Acquisition: Toddlers As Data Miners

February 7, 2008

Indiana University researchers are studying a groundbreaking theory that young children are able to learn large groups of words rapidly by data mining.

They are studying whether this phenomenon contributes to a system approach to language learning that helps explain the ease by which 2- and 3-year-olds can learn one word at a time. Once understood, the learning mechanisms used by the children could be used to further machine… read more

Researchers close to delivering molecular circuits

February 20, 2002

Molecular electronics researchers are converging on viable circuit-fabrication methods. A Hewlett-Packard and UCLA team are tackling one universal problem with molecular circuits: the inherent defects created by any chemical reaction. They’re designing a molecular equivalent of an FPGA (floating point gate array) that can be used to implement a redundant wiring scheme in which defective cells are simply switched out of the network.

The team is also working on… read more

Stephen Hawking: ‘Humans Have Entered a New Stage of Evolution’

July 6, 2009

The rate of biological evolution in humans is about a bit a year, compared to 50,000 new books published in the English language each year, containing on the order of a hundred billion bits of information, Stephen Hawking says.

This means we are now entering a new phase of evolution — “self designed evolution” — in which we will be able to change and improve our DNA, and during… read more

New technology could inspire brain implant for detecting, treating seizures

June 2, 2011

Researchers at the University of Pittsburgh have developed a novel technology to precisely modulate individual neurons in rats, allowing the molecular, neuronal, and circuit functions to be analyzed with unprecedented precision.

The researchers demonstrated a novel way of loading specific drugs onto an array of electrodes and triggering their release into cultured rat neurons, allowing for more precise insight into the cellular mechanisms of neuronal… read more

VR headset spots concussion in minutes

April 28, 2005

A virtual-reality headset is being developed that can diagnose the extent of a head injury within minutes.

The system puts the wearer through an array of neuropsychological tests designed to pick up reduced reaction times and deficits in working memory, conditions that would indicate injuries to different parts of the brain.

By measuring reaction times in a battery of tests, the system is designed to detect even mild… read more

Just Desserts: Artificial Sweeteners Linked to Weight Gain

February 12, 2008

Purdue University researchers report that artificial sweeteners may make it harder to lose weight, possibly because the sweetness without calories confuses the body’s appetite and metabolism controls.

Rats given yogurt sweetened with saccharin ended up eating more and gaining more weight and body fat than rats given yogurt containing glucose.

Computer Screen Controlled with Monkeys’ Brain Signals

March 18, 2002

Researchers at Brown University have demonstrated that brain patterns can be used to control machines. The development could lead to techniques that allow paraplegics to articulate artificial limbs through thought alone.In the experiment, which resembled a computer game, monkeys initially used a joystick to chase red and purple dots around a screen.

Then, unknown to the monkeys, the joystick was disconnected — but the animals were still able to… read more

Sequencing a Genome a Week

July 15, 2009

The Human Genome Project took 13 years to fully sequence a single human’s genetic information. At Washington University’s Genome Center, they can now do one in a week. But when you’re generating that much data, just keeping track of it can become a major challenge….

Design by DNA

May 12, 2005

DNA molecules provide the architecture for all living things. New York University chemist Ned Seeman thinks they could also be a perfect assembly platform for the smallest computing devices ever built.

‘Junk’ RNA May Have Played Role in Vertebrate Evolution

February 15, 2008

Dartmouth College and University of Bristol researchers report that microRNA transcribed from “junk DNA” could be responsible for the evolution of animals with backbones.

They found a surfeit of microRNA in the genomes of the earliest vertebrates, such as lampreys (jawless fish), compared with invertebrates like sea squirts.

Big Brains Rule Trading Floor

April 17, 2002

“A growing number of tech-savvy traders…[are creating] programs to make the computer a tool for making small-scale pricing decisions, the task traditionally performed by traders.”

Mismatched materials produce self-assembling gears

July 24, 2009

Columbia University engineers have devised gears and cogs that make themselves, formed from polymer discs that buckle into shape after a change in temperature.

The key is to adjust the polymer’s properties so that it shrinks preferentially in a preferred wrinkle direction, generating all kinds of teeth patterns.

Attaching amino acids to electronic device materials

May 26, 2005

Researchers at Lucent Technologies’ Bell Laboratories has tested the adhesion of amino acids to semiconductors, metals and insulators used in electronic devices. The team used their results to design an inorganic nanostructure that selectively bound to a particular primary peptide sequence.

Their results could have applications ranging from biomolecular detection to biomolecular manipulation and basic biological molecule studies, such as X-ray analysis of proteins or intracellular peptide assays.

Study identifies new patterns of brain activation used in forming long-term memories

February 21, 2008

New York University and Weizmann Institute of Science researchers have identified patterns of brain activation linked to the formation of long-term memories in a simulated real-life experience, finding activity in new areas of the brain: the temporal pole, superior temporal gyrus, medial prefrontal cortex, and temporal parietal junction.

Previous studies had not simulated the real-world settings in which long-term memories are typically formed, and found only that medial temporal… read more
