Diabetes heart risk ‘can be cut’

May 22, 2009

A Cambridge University study of 33,000 people found getting blood sugar levels closer to the level for healthy people — 4% to 5% — could cut the risk of heart attacks by 17%.

The current recommended level in the UK is 7%.

TiVo to Feature Web Video

January 8, 2008

TiVo Inc. said Monday its subscribers will soon be able to select video from the Web for playback on televisions through its digital video recording service, building on its strategy to extend its DVR beyond regular TV.

Self-forming biological scaffolding

A model system that can interpret the role of cross-linking proteins
September 20, 2012

bio_scaffolding

A new model system of the cytoskeleton (cellular skeleton) of living cells is akin to a mini-laboratory designed to explore how the cells’ functional structures assemble.

Physicist Volker Schaller and his colleagues from Technical University in Munich, Germany, presents one hypothesis concerning self-organization. It hinges on the finding that a homogeneous protein network, once subjected to stresses generated by molecular motors, compacts into highly condensed fibers.… read more

Using nanoparticles, in vivo gene therapy activates brain stem cells

July 26, 2005

University at Buffalo scientists have delivered genes into the brains of living mice with no observable toxic effect.

Scientists used gene-nanoparticle complexes to activate adult brain stem/progenitor cells in vivo, demonstrating that it may be possible to “turn on” these otherwise idle cells as effective replacements for those destroyed by neurodegenerative diseases, such as Parkinson’s.

In addition to delivering therapeutic genes to repair malfunctioning brain cells, the nanoparticles… read more

Chrome browser integrates speech technology using HTML5

April 7, 2011

Google’s latest Chrome browser integrates speech-to-text capabilities.

Google has been working with the World Wide Web Consortium’s HTML Speech Incubator Group to determine the feasibility of integrating speech technology in HTML5, the Web’s new, emerging standard language.

A Web page employing the new HTML5 feature could have an icon that, when clicked, initiates a recording through the computer’s microphone, using Google’s Chrome browser. Speech is captured and sent… read more

Only the Strong Survive

August 12, 2002

Santa Fe Institute research computer scientist Melanie Mitchell is studying how natural systems perform computation and says we can solve some complex problems by letting systems evolve solutions through a process of natural selection.

Restoring Sight

Scientists aim to treat retinitis pigmentosa by developing novel gene therapies using channelrhodopsin-2 (a light-sensitive protein derived from algae) and similar tools to make different retinal cells, such as bipolar cells (shown in pink in the middle section of the photo), responsive to light.

Scientists believe that channelrhodopsin targeted toward different cell types could ultimately treat a broader range of diseases, including Parkinson’s and epilepsy.

Researchers enable solar cells to use more sunlight

March 4, 2015

Scientists of the University of Luxembourg and of the Japanese electronics company TDK have extended sensitivity of a conductive oxide film used in solar cells in the near-infrared region to use more energy of the sun and thus create higher current.

Similar attempts have been made before, but this is the first time that these films were prepared by a one-step process and, at the same time, stable in… read more

Crash Warning System Monitors Nearby Traffic And Warns Of Possible Collisions

January 14, 2008

European researchers have demonstrated a software-based collision warning system for cars that could alert the driver several seconds in advance of an impact.

The Collision Warning System prototype finds the position, speed and trajectory of neighboring and oncoming traffic using GPS and the Vehicle2Vehicle (V2V) car communication protocol.

A step toward the $1,000 personal genome using readily available lab equipment

August 5, 2005

The theoretical price of having one’s personal genome sequenced just fell from the prohibitive $20 million dollars to about $2.2 million, and the goal is to reduce the amount further–to about $1,000–to make individualized prevention and treatment realistic.

The sharp drop is due to a new DNA sequencing technology developed by Harvard Medical School researchers.

The new technique calls for replicating thousands of DNA fragments attached to one-micron… read more

The Even-More-Compact Disc

August 30, 2002

The new miniaturized DataPlay digital media offers CD performance and 500 MB storage at a tiny size but at expensive prices initially for media and players.

DataPlay discs will be available in blank, recordable form as well as prerecorded, copy-protected albums.

Targeting the Brain with Sound Waves

Ultrasonic waves could one day be used as a noninvasive alternative to deep-brain stimulation (DBS) and vagus nerve stimulation in treating neurological disorders, says William Tyler, a neuroscientist at Arizona State University, who has started a company called Supersonix to commercialize the technology.

3D-printed sensors to lower cost, improve comfort in diabetes management

Engineers at Oregon State University have used additive manufacturing to create an improved type of glucose sensor for patients with Type 1 diabetes, part of a system that should work better, cost less, and be more comfortable for the patient.

A key advance is use of an electrohydrodynamic jet (“e-jet” printing) to make the sensor, which detects glucose concentration based on electric current… read more

Nanotubes Help Advance Brain Tumor Research

January 17, 2008

The potential of carbon nanotubes to diagnose and treat brain tumors is being explored through a partnership between NASA’s Jet Propulsion Laboratory and City of Hope.

They plan to functionalize and attach inhibitory RNA to nanotubes and deliver it to specific areas of the brain. It could also be used to treat stroke, trauma, neurodegenerative disorders and other disease processes in the brain.
