You know that thing that water does when it boils? The thing with the bubbles? Turns out, it doesn't really need to do that at all, with scientists finding a way to make boiling water a completely bubble-free zone. Researchers from Northwestern University, King Abdullah University of Science and Technology in Saudi Arabia and Melbourne University in Australia teamed up to prevent water from bubbling when it boils by using tiny spheres coated with a hydrophobic material.  Read More

The tiny hairs on the 'nano-velcro' particles trap heavy metal ions in their grasp allowin...

While progress has been made in reducing the amount of heavy metal pollution, the very nature of heavy metal contamination means it continues to be a problem in waterways around the world. Conventional heavy metal contamination detection methods require sending samples off to a lab for analysis on expensive equipment. Now a Swiss-American team has developed a cheap way to immediately ascertain the levels of heavy metals in lakes and rivers and the fish pulled out of them.  Read More

MOFs are composed of organic linkers held together by metal atoms, and this results in a m...

Researchers at Northwestern University, Illinois, have broken a world record in the creation of two synthetic materials, named NU-109 and NU-110, which have the greatest amount of surface areas of any material to date. To put this into perspective: if one were able to take a crystal of NU-110 the size of a grain of salt, and somehow unfold it, the surface area would cover a desktop. Additionally, the internal surface area of just one gram of the new material would cover one-and-a-half football fields.  Read More

A newly-developed electronic finger cuff could lead to smarter surgical gloves that make p...

Using industry-standard manufacturing technology, researchers have integrated ultrathin and stretchable silicon-based electronics, sensors and actuators on an artificial skin that can be worn on the tip of your fingers. The result is an artificial finger cuff that could be used to produce the ultimate hi-tech surgeon's glove, capable of sensing the electrical properties of tissue, removing it locally, or even performing ultrasound imaging with a simple touch.  Read More

New 'rubber-band electronics' technology could pave the way for flexible, stretchable medi...

In the quest to develop implantable electronics to monitor the human body from within, flexibility and stretchability have been major hurdles. We’ve seen numerous developments including stretchable LED arrays, an implantable device for measuring the heart’s electrical output, and an electrode array that melts onto the surface of the brain. Now researchers have developed technology that combines a porous polymer and liquid metal that allows electronics to bend and stretch to more than 200 percent their original size.  Read More

A new, stable dye-sensitized solar cell developed at Northwestern University promises to b...

Solar power is up there as the quintessential clean energy and there’s a race worldwide to develop better solar cells to overcome current challenges related to cell efficiency, manufacturing costs, durability and materials, among other things. One of the latest developments in the sector comes from Northwestern University where researchers have developed a stable dye-sensitized solar cell that may one day prove cheaper than silicon-based cells.  Read More

Researchers at Northwestern University have developed a neuroprosthesis that restores complex movement in the paralyzed hands of monkeys. By implanting a multi-electrode array directly into the brain of the monkeys, they were able to detect the signals that generate arm and hand movements. These signals were deciphered by a computer and relayed to a functional electrical stimulation (FES) device, bypassing the spinal cord to deliver an electrical current to the paralyzed muscles. With a lag time of just 40 milliseconds, the system enabled voluntary and complex movement of a paralyzed hand.  Read More

Gold nanostars like these are able to deliver drugs directly into the nucleus of cancer ce...

While effective at killing cancer cells, chemotherapy is currently a shotgun approach that can also harm healthy cells and cause serious side effects in patients. The ability to deliver drugs directly into cancer cells would provide a more targeted approach to more effectively treat the disease with lower doses of drugs and less side effects. Researchers at Northwestern University are claiming to be the first to develop gold nanostars that provide a much more precise approach by delivering a drug directly to a cancer cell’s nucleus.  Read More

Smartphone apps are currently being developed to keep people from turning to drugs, or soc...

Some day, perhaps soon, it's possible that your smartphone could stop you from shutting yourself off from the world, or turning to illicit substances to deal with the stresses of life. Two separate studies are currently under way, looking at how smartphone-enabled technologies could be used to monitor peoples' levels of stress or depression, and then take action to keep them from making the wrong choices.  Read More

Squid uses EMG sensors to keep track of the electrical activity of muscles during a workou...

Unless you have a personal fitness instructor following you around with a notepad, keeping track of your progress at the gym can be a real nuisance. Luckily, thanks to a group of students from from Northeastern University in Boston, you can now count on your squid-equipped shirt to do the statistical heavy lifting for you. Squid is essentially a set of electromyography (EMG) sensors attached to a box that pushes your workout data to a smartphone app. This is synchronized with a web-based management panel, to give you a detailed overview of your progress.  Read More
