Promising antibacterial coating created from green tea and salt

By - August 23, 2013 1 Picture
Researchers at Northwestern University have discovered new ways of utilizing the properties of naturally occurring polyphenols found in green tea, red wine and dark chocolate. Dissolving polyphenol powders in water with a small amount of salt instantly produces transparent coatings that kill bacteria on contact, have antioxidant qualities and are non-toxic. The sticky nature of polyphenols and the low cost of materials could open the door to a wide range of uses for these coatings. Read More

The two faces of the "love hormone"

By - August 6, 2013 2 Pictures
Often called the love hormone, oxytocin has shown the ability to enhance social bonding, decrease anxiety and encourage an overall feeling of satisfaction with life. A new study out of Northwestern University, however, finds that this ancient hormone has a dark side, and is capable of strengthening unpleasant memories, fear, and anxiety. This Jeckyll and Hyde behavior results from the fact that oxytocin has a general strengthening effect on social memories, without regard to their polarity. Read More

Experimental procedure shows promise for treatment of MS

By - June 11, 2013 1 Picture
In multiple sclerosis, the body’s immune system attacks and damages myelin, which is the insulating layer on nerves in the spinal cord, brain and optic nerve. Just as would happen with an electrical cord with compromised insulation, this causes the nerves to short-circuit and cease functioning properly. An international team of scientists, however, have recently reported success in the first phase of clinical trials in which MS victims’ immune systems were conditioned to become much more tolerant of myelin.

Non-toxic corn starch could replace cyanide in gold mines

By - May 14, 2013 1 Picture
In the gold-mining process, the precious metal is often extracted from low-grade ore in a technique known as gold cyanidation. As its name suggests, the process utilizes highly-poisonous cyanide, some of which ends up entering the environment in the mines’ tailings. That’s not so good. Scientists at Illinois’ Northwestern University, however, recently announced their discovery of a new gold recovery process that’s based on a non-toxic component of corn starch. Read More

Experimental lithium-ion battery can be stretched, twisted and wirelessly charged

By - February 27, 2013 3 Pictures
Thanks to the advent of stretchable electronics, we’re currently witnessing the development of things like smart fabrics, bendable displays, and even pressure-sensitive skin for robots. In many potential applications, however, the usefulness of such electronics would be limited if they still had to be hooked up to a rigid battery. In response to that problem, a team of scientists have recently created – you guessed it – a stretchable lithium-ion battery. Read More

"Transient electronics" dissolve once they're not needed

By - September 27, 2012 6 Pictures
We’ve certainly been hearing a lot lately about tiny electronic devices that can do things such as delivering medication after being implanted in the body, measuring structural stress upon being attached to a bridge, or monitoring pollution after being placed in the environment. In all of these cases, the device has to be retrieved once it’s served its purpose, or just left in place indefinitely. Now, however, an interdisciplinary team of researchers have demonstrated “transient electronics,” which dissolve into nothing after a pre-determined amount of time. Read More
