Two ambient backscatter test devices are able to communicate, despite having no batteries ...

In order for the Internet of Things to become a reality, devices will need to be able to communicate with the internet and with one another. If they have to be powered up in order to so, however, a lot of electricity is going to be wasted. That’s where a new technology known as “ambient backscatter” comes into the picture. Developed by engineers at the University of Washington, it uses ever-present existing TV and cellular signals to provide the power and medium for battery-less communications.  Read More

LED light bulbs may be more energy-efficient and longer-lived than their incandescent equivalents, but they’re also considerably more expensive to purchase. This is largely because rare earth elements (REEs) are used in their phosphors. There are hazards involved in the mining and processing of REEs, plus China is responsible for almost the entire world’s supply, so they’re becoming increasingly pricey. Now, however, scientists have come up with a plentiful alternative material that they say is much more environmentally friendly, and that should drive down the price of LEDs.  Read More

A WiSee user could control their TV using gestures, even if a wall separated them and the ...

By now, even if they’ve never used one themselves, most people are pretty familiar with the idea behind gesture control systems such as the Kinect – the user makes a movement, the device “sees” that movement, and interprets it. However, what would happen if the user was in another room, blocked from the device’s cameras and depth sensors? Well, as long as there was a Wi-Fi signal available, it wouldn’t be a problem ... at least, not if the WiSee system was being used.  Read More

A collagen 'wall' (blue, at left) built up around an implanted material vs. more evenly-di...

No matter what sort of wondrous implantable medical devices are created, they’re not going to do anyone much good if the recipient's body simply rejects them. With that in mind, scientists at the University of Washington have developed a synthetic biomaterial that they claim is “exceptional” at keeping implanted materials from being attacked by the immune system.  Read More

Artist's concept of a fusion-drive ship

Traveling through deep space is a hazardous undertaking and choosing the right engine can mean the difference between a fast, successful mission and a slow one with mounting dangers of radiation sickness, equipment failures and personal conflicts. A team of researchers from the University of Washington (UW) and Redmond, Washington-based MSNW are aiming to expand the options by developing a new fusion drive rocket engine that promises to make possible a manned spacecraft that could reach Mars and return to Earth in months rather than years.  Read More

Better understanding the structure of the humulone molecule found in hops could lead to mo...

A beer a day might not keep the doctor away but hops, one of the basic ingredients in beer brewing, could be good for you. In a development that could lead to better drug treatments of diabetes and cancer, University of Washington research associate professor of chemistry, Werner Kaminsky, has determined the exact structure of humulones and their derivatives – the acids in hops that give beer its distinctive bitter taste.  Read More

An electron microscope image of the fabric, complete with blocked sperm

While condoms are the only things that protect against both unwanted pregnancies and HIV, a lot of people aren’t big fans of stopping to put them on. Additionally, women are sometimes put in an awkward role, needing to pressure the man to use the thing – although female condoms certainly do exist, their bulkiness makes them rather unpopular. Now, however, a team of scientists from the University of Washington are working on a type of dissolvable fabric that could be used by women both for contraception and HIV protection.  Read More

Researchers at the University of Washington have found a way to turn scraps of common offi...

A group of researchers at the University of Washington has found a way to isolate and identify medically interesting molecules using little more than scraps of office paper, a Ziplock bag and a cheap diluted solvent. If properly developed, the system – which requires minimal costs and know-how to build and operate – could be made to administer a wide range of medical tests nearly free of charge.  Read More

SpiroSmart allows users who suffer from lung-related conditions to monitor their health st...

A new Smartphone application designed by researchers at the University of Washington, UW Medicine and Seattle Children’s Hospital has the potential to save the lives of people suffering from asthma and other respiratory diseases by allowing them to measure lung functions, so far only possible with spirometers, with nothing but a smartphone.  Read More

Researchers have discovered a chemical that makes cells in the retinas of blind mice sensitive to light, temporarily restoring some vision. They are working on an improved compound that they hope could one day be used to restore sight in human patients suffering from retinitis pigmentosa, the most common form of inherited blindness, and macular degeneration, the most common cause of acquired blindness in the developed world.  Read More
