Brain Images Predict Suicide Risk

April 22, 2010

Predict Stack

UCLA researchers are using “quantitative EEG” (QEEG) — an algorithm that mathematically analyzes data from EEG electrodes to transform the results into a map of brain activity — to detect markers of antidepressant-induced suicidal thoughts.

Patients on antidepressants who indicated an increase in suicidal thoughts showed a drastic decrease in activity in the midline- and right-frontal (MRF) portion of the brain just 48 hours after starting their meds–six times… read more

Planck satellite closer to revealing the cosmic blueprint

February 15, 2012

Planck_Molecular_Clouds

The European Space Agency (ESA)’s Planck mission has revealed that our Galaxy contains previously undiscovered islands of cold gas and a mysterious haze of microwaves.

These results give scientists new treasure to mine and take them closer to revealing the blueprint of cosmic structure.

These results include the first map of carbon monoxide to cover the entire sky. Carbon monoxide is a constituent of the cold… read more

Heart stem cells discovered by three teams

November 23, 2006

Cardiovascular “precursor” cells from cultures of mouse embryonic stem cells, dubbed “master” heart cells, hold the promise of treating patients with serious cardiovascular disease by rebuilding both cardiac muscle and blood vessels.

Self-assembling polymer arrays improve data storage potential

August 15, 2008

University of Wisconsin-Madison and Hitachi have achieved higher data-storage density by using self-assembling block copolymers to shrink the size of the pattern manufacturing templates used in disk drives and other data-storage devices, paving the way to smaller electronic devices and higher-capacity hard drives.

When added to a lithographically patterned surface, the copolymers’ long molecular chains spontaneously assemble into the designated arrangements, down to the molecular level. The method offers… read more

Verizon trumps Wi-Fi with 500 k/bits

January 9, 2004

Verizon is rolling out its “BroadbandAccess” (300 to 500 kbit/s, with with bursts of 2 Mbits/s) cell phone service nationwide this year.

Verizon promises its “iobi” service will offer features such as programmable call forwarding or voice mail showing up as email and much closer integration between landline, IP and cellular networks.

Bioengineer calls for personal health devices

April 29, 2010

A growing set of nanoscale components are emerging from the lab that someday will power handheld devices that can provide custom health care advice, marrying novel bioengineering components with existing computer and consumer technologies, says Luke P. Lee, professor of bioengineering, University of California, Berkeley.

The new devices he envisions could, for example, “examine your physiological data every week and help you behave based on examining very sensitive biomarkers… read more

Pocket Projectors

December 6, 2006

Microprojector technology could let handheld gadgets like mobile phones and iPods display big pictures. The The Microvision system, composed of semiconductor lasers and a tiny mirror, will be small enough to integrate into a phone or an iPod.

California Licenses 2 Companies to Offer Gene Services

August 21, 2008

California has granted business licenses to companies that offer consumers information about their genes: Navigenics and 23andMe, requiring doctors to be involved in ordering genetic tests.

Both offer services, costing from $1,000 to $2,500, that scan a person’s whole genome, providing a variety of information about the risk of various diseases.

New York State also has taken action against at least 31 genetic testing companies, saying they cannot… read more

An Ultrasound That Navigates Every Nook and Cranny

January 20, 2004

A highly miniaturized silicon-based ultrasound device is being developed that could be placed inside the body to gather images of artery-harming plaque from inside the arteries themselves.

The “capacitive micromachined ultrasonic transducers” might one day appear in other medical applications, from portable prenatal screeners to hand-held scanners used on battlefields to check the injured for internal bleeding.

New U.S. Push to Regulate Internet Access

May 6, 2010

The Federal Communications Commission plans to propose regulating broadband lines under decades-old rules designed for traditional phone networks, and wants to adopt “net neutrality” rules that require Internet providers to treat all traffic equally, and not to slow or block access to websites.

Cable and telecommunications executives have warned that using land-line phone rules to govern their management of Internet traffic would lead them to cut billions of capital… read more

New surgical center is a big technological cut above the rest

December 15, 2006

The movie magic that allowed Gollum to lurch across the screen in the Lord of the Rings films or capture the great ape’s naturalistic movements in the remake of King Kong is now being used in operating room research and training in the new Maryland Simulation Training and Innovation Center at the University of Maryland Medical Center.

By recording how expert surgeons move during simulated surgeries, researchers hope to… read more

A Genetic Link for Vision Loss

August 28, 2008

Researchers from multiple institution have identified a genetic link associated with dry macular degeneration, which they say may lead to treatments for the debilitating disease.

Top chip makers tout nanotechnology

February 5, 2004

Nanotechnology will play a key role in next-generation silicon, according to researchers.

Promising technologies include crossed nanowire structures that form matrices, transistors that use a single electron to control current flow, and carbon nanotubes, which may extend CMOS scaling down to the 1 to 3 nm range.

IBM has applied a molecular “self-assembly” technique to nanotechnology and recently applied it to flash memory devices.

Modern cars vulnerable to malicious hacks

May 14, 2010

Using a laptop and custom-written software, researchers at University of Washington and University of California, San Diego were able to hack into the control systems of a car.

In tests done wirelessly via the Internet, they demonstrated that they could disable the brakes and turn off the engine while the vehicle was moving at 65 kilometres per hour.
