Stick-on electronic patches for health monitoring

Better than fitness trackers on your wrist or clipped to your belt, the inventors say
April 7, 2014


Engineers at the University of Illinois at Urbana-Champaign and Northwestern University have developed soft, thin stick-on patches that stretch and move with the skin, using commercially available, off-the-shelf chip-based electronics for sophisticated wireless health monitoring.

The patches stick to the skin like a temporary tattoo and incorporate a unique microfluidic construction, with wires folded like origami to allow the patch to bend and flex without being constrained by the… read more

Sticky future for the spider suture

November 2, 2009

University of Wyoming scientists have identified the genes potentially involved in the glycoprotein-based ultra-strong glue that spiders use to trap their prey, raising the hope that similar substances could one day be synthezised to produce surgical adhesives.

Sticky Nanotape

October 10, 2008

University of Dayton and Georgia Tech scientists have developed an adhesive made of carbon nanotubes whose structure closely mimics that of gecko feet, but is 10 times more adhesive, and could aid climbing robots.

Sticky tape emits useful terahertz rays

August 3, 2009

Peeling sticky tape can generate terahertz radiation, raising the possibility of a cheaper alternative to lasers for medical imaging.

Still Waiting for Personalized Medicine

November 28, 2006

Pharmacogenomics–a field whose researchers aim to let doctors tailor prescriptions to their patients’ genetic makeups–is one of the most tantalizing promises of the genomic era: quick and easy tests that tell you which drugs to take or what dose is right for you.

A few tests have been developed for specific diseases, such as cancer–most notably a genetic test that predicts which lung cancer patients will respond to some… read more

Still Waiting on Neural Nets

August 13, 2001

Neural network technology needs to connect with current research about how the human brain works, said researchers gathered at a session of the International Joint Conference on Neural Networks in Washington, DC in July.
Jim Olds, director of George Mason University’s Krasnow Institute for Advanced Study in Fairfax, VA, remarked that the information about brain function that computer scientists have been relying on is about 30 years old.

Stimulating brain cells with light to combat Parkinson’s disease

October 29, 2012


Lund University researchers plan to use optogenetics to stimulate neurons to release more dopamine to combat Parkinson’s disease.

Optogenetics allows scientists to control specific cells in the brain using light, leaving other cells unaffected.

To do this, the relevant cells are equipped with genes that express a special light-sensitive protein. The protein switches on cells when they are illuminated with light from a thin optic fiber… read more

Stimulating Healing in the Heart

Cardio Heal B

CardioHeal, based in Brookline, MA, is developing peptide drugs that can spur growth of new heart muscle cells in the human body.

Stimulating Nerve Cells with Infrared Lasers

October 27, 2004

Vanderbilt University researchers have discovered a method that uses laser light, rather than electricity, to stimulate and control neurons.

They discovered in an experiment with rats that low-intensity infrared laser light can activate specific nerves, exciting a leg or even individual toes without actually touching the neurons. Immediately following the experiment, the rats regained full use of their legs with no signs of weakness or damage.… read more

Stimulating Sight: Retinal Implant Could Help Restore Useful Level Of Vision To Certain Groups Of Blind People

September 24, 2009

(Shawn Kelly)

Scientists from MIT and other organizations have developed a new prototype of a less invasive retinal prosthesis to be implanted behind the retina to take over the function of lost retinal cells by electrically stimulating retinal neurons.

A camera mounted on a pair of glasses sends images to a microchip attached to the eyeball. The glasses also contain a coil that wirelessly transmits power to receiving coils surrounding the… read more

Stimulus Funding for Solar and Geothermal

May 28, 2009

President Obama has announced $467 million in funding for solar and geothermal power from the recovery bill signed in February — most of the money for research and development.

Stink bomb gas puts mice into suspended animation

April 21, 2005

Suspended animation has been deliberately induced in a species of mouse which does not naturally hibernate, using hydrogen sulphide.

If a similar response could be triggered in humans, there would be major healthcare benefits and the futuristic idea of putting astronauts into suspended animation on long-haul space flights could move a step closer to reality.

Stock exchange for ‘grid’ computing?

February 26, 2008

Computer scientists and economists in Spain, the UK, Italy and Germany have developed a successful decentralized, free-market approach to grid computing.

Called CATNETS, it showed that a free-market network can be much bigger than a centrally administered one without becoming bogged down by administrative overheads.

Stomach hormone turns hungry people into junkies

May 7, 2008

When volunteers received a dose of a natural hunger-inducing hormone called ghrelin, their brains responded to pictures of food in the same way that addicted people’s brains do to cigarettes or drugs, says Alain Dagher, a neurologist at McGill University.

Made in the stomach, ghrelin levels rise when people are hungry and wane after a meal. This mechanism probably helped humans to load up on life-saving calories when food… read more

Stomach-acid-powered micromotors tested in living animal

January 28, 2015

Zinc stomach micromotors

Imagine a micromotor fueled by stomach acid that can take a bubble-powered ride inside a mouse — and that could one day be a safer, more efficient way to deliver drugs or diagnose tumors for humans.

That’s the goal of a team of researchers at the University of California, San Diego.

The experiment is the first to show that these micromotors can operate safely in… read more
