Rumours that first dark matter particle found

December 9, 2009

The physics blogs are abuzz with rumors that a particle of dark matter* has finally been found in the Cryogenic Dark Matter Search experiment.

* Dark matter is hypothetical matter that is thought to make up 23 per cent of the mass density of the universe.

A New Approach to Treating Alzheimer’s

May 12, 2008

Neurosurgeon Andres Lozano at the University of Toronto is testing electrical stimulation of the hypothalamus as a novel treatment for Alzheimer’s disease.

Immortality Institute’s Second Book Project invites abstracts

June 26, 2006

The Immortality Institute is inviting abstracts for possible chapters in a forthcoming anthology on the science and ethics of life extension.

ImmInst’s first book, “The Scientific Conquest of Death,” is available online and includes eighteen essays from leading scientists such as Aubrey de Gray, Ray Kurzweil, Marvin Minsky, Robert Freitas, Nick Bostrom, Max More, Mike West and William Sims Bainbridge.

Free online journal gives sneak preview

August 20, 2003

The Public Library of Science has released a sneak preview of the research papers it will be giving away for free from October. Its first journal, PLoS Biology, is a monthly, peer-reviewed journal intended to compete head-to-head with the most prestigious paid-for journals.

SearchTrends Shows What’s Hot In The Search World On The iPhone

December 16, 2009

SearchTrends for the iPhone displays real-time search trends for Google, Yahoo!, Bing, and Twitter, and lets you search on these terms from within the app.

Instead of relying on news sources, you’re keying off of what people around the world are talking about in real time.

Robotic suit could usher in super soldier era

May 16, 2008

An exoskeleton that multiplies a soldier’s strength and endurance as many as 20 times has been developed by Sarcos Inc.

It could also allow factory workers someday using the technology to perform manual labor more easily, and firefighters more quickly carrying heavy gear up stairwells of burning buildings. Disabled people also may find uses for the technology.

Make way for the terabyte laptop drive

July 7, 2006

Seagate Technology Inc. plans to increase disk capacity by 10 times with new technology it has just patented, meaning a computer hard drive could soon be storing as much as a terabyte of data.

The Heat-Assisted Magnetic Recording (HAMR) technology created by Seagate includes nanotube-based lubrication to allow the read/write head of a disk to get closer to the surface and store more information.

New knowledge about ‘flawed’ diamonds could speed the development of diamond-based quantum computers

October 14, 2011

Calculated energy surface of the 3E excited state of a diamond nitrogen-vacancy center as a function of distortions, a shape that is often referred to as a "warped Mexican hat" (credit: University at Buffalo)

A University at Buffalo-led research team has established the presence of an important effect in defective diamonds, a finding that will help advance the development of diamond-based systems in applications such as quantum information processing.

“We normally want things to be perfect, but defects are actually very important in terms of electronic applications,” said Peihong Zhang, the UB associate professor of physics who led the… read more

Is it time to move beyond zeroes and ones?

August 27, 2003

The economics of semiconductor manufacturing now is forcing us to consider moving beyond binary to ternary and quaternary logic.

This would effectively increase a device’s information density without further shrinking the transistor structure. This option should be considered as we move ultimately into the sub-nanometer range, where we are already facing problems relating to the cost of the fabrication equipment and more fundamentally, quantum uncertainties.

Video Startup Thwapr Doesn’t Bother With iPhone App, Shoots for 400 Million Users

December 23, 2009

Thwapr lets mobile phone users share photos and videos via SMS (texting) — no app required, and supports 169 mobile handsets, as well as PCs and Macs.

Full size replacement ‘Neo-Bladders’ do well in animal models

May 21, 2008

Researchers at the biotechnology company Tengion have successfully grown replacement urinary bladders in large mammals within six months after implantation, which may lead to FDA clearance to initiate clinical trials on humans in 2009.

These fully functional replacement bladders were produced from autologous (each individual’s own cells) bladder cells seeded onto a biodegradable scaffold and then surgically implanted into 23 large mammals.

Stuck Pig

July 14, 2006

Gryonic suspension may be just a few years away from clinical trials on humans, based on successful suspended animation with hundreds of pigs for an hour at a time.

Eye-tracking allows for more creative computer-aided design

October 24, 2011

Designing with Vision, a system using eye-tracking technology, has been developed by researchers at The Open University and the University of Leeds to give computer-aided design users a more fluid human-machine interface.

The software can identify and select shapes of interest automatically within a drawn sketch. The combination of eye-tracking technology and conventional mouse-based input allows initial design sketches to be manipulated and… read more

No More Human Guinea Pigs

September 9, 2003

DARPA’s “Virtual Soldier” program plans to create an army of digital test subjects that can be subjected to new drugs, new medical procedures—even new weapons—without using soldiers as human guinea pigs. The “Virtual Soldier” will be an exact, computerized copy of every part of a person’s body.

Scientists discover a controller of brain circuits

December 29, 2009

A Johns Hopkins neuroscientist has found that semaphorin proteins regulate the number of synapses and their distribution in the part of the brain involved in conscious thought, which could have an impact on how scientists think about the early origins of autism, schizophrenia, epilepsy and other neurological disorders.
