Scientists close in on computers that work like the human brain

Scientists have been working since 2008 to develop technology based on memristors (short for memory resistors), which promise computers that need never boot up and function more akin to the human brain – like neurons, they can retain information and perform logic operations. Now scientists at Northwestern University have made a new breakthrough that may make possible brain-like computing capabilities.  Read More

The new tool is designed to be clinically beneficial and socially engaging (Image: Christi...

A combined research effort between MIT and Northwestern University has led to the development of a new socially engaging tool designed to help people cope with depression. Focusing on a technique known as cognitive reappraisal, the application allows members to both receive help from others, and offer it themselves.  Read More

Don't throw that graphene away – its holes are proton-friendly (Image: University of Minne...

We already knew that graphene was a highly useful material, but just how useful is it? Well, it turns out that even defective graphene may be valuable. According to a team of mostly-American scientists, improperly-formed graphene could find use in next-generation fuel cells. Among other things, those cells might allow electric cars to be recharged in the amount of time that it currently takes to refuel a gas-burning vehicle.  Read More

The new MOH material could be used to make better gas masks and suits for soldiers and eme...

While the Iran-Iraq war of 1981-1988 saw the only large-scale use of chemical weapons since WWII, in a world beset by rogue states, civil wars, and terrorism, protecting against nerve agents and disposing of them remains a major problem. One bright spot is a team from Northwestern University, which has developed a new material capable of neutralizing nerve gases. The zirconium-based Metal-Organic Framework (MOF) called NU-1000 is not only useful for disposing of stockpiles of such toxins, but also for use in gas masks and protective suits for soldiers and rescue workers.  Read More

A new theoretical result could lead to designing semiconductors with ideal efficiency for ...

Solar cell efficiency has made significant strides in recent times, but cells are still far from their maximum theoretical efficiency, and part of the reason is that the semiconductors we use to build them don’t have ideal electrical properties. Researchers at Northwestern University have now found a way to tweak an important electrical feature of transition metal oxides, compounds commonly used as semiconductors, to build the optimal light-absorbing material for solar cells, lasers and photoelectrochemical cells.  Read More

An illustration depicting a ruptured ACL (Image: Shutterstock)

If you follow sports at all, then you've probably heard about athletes rupturing their ACL, or anterior cruciate ligament. It connects the femur to the tibia, and once it breaks, it's incapable of healing. Treatment most often involves reconstructing the ACL using grafts from the patellar tendon, which connects the patella (aka the kneecap) to the tibia – although this can present problems of its own. Now, scientists at Northwestern University in Illinois are creating a man-made replacement ACL, which could make treatment much more effective.  Read More

A new MRI technique could lead to early detection of Alzheimer’s Disease

The development of brain plaques are thought to correlate with symptoms of Alzheimer’s disease, such as memory loss. Previous research has indicated that limiting these buildups could be the key to tackling the disease, but scientists from Northwestern University are digging a little deeper. The team has devised a non-invasive MRI technique capable of tracking the specific toxins that accumulate to form plaques, potentially enabling doctors to pick up early signs of the disease before it starts to take hold.  Read More

According to researchers, Blu-ray disc patterns markedly improve the efficiency of solar c...

Blu-ray discs have proven themselves superior to DVDs as storage media in light of their high capacity, high definition, and higher transfer rate. Now researchers claim that Blu-ray discs have one more advantage over DVDs: they also have the ability to help markedly improve the efficiency of solar cells, when their etched information patterns are repurposed for use as light concentrators.  Read More

Ampy is also pocketable at 3 inches square

Kinetic chargers have been around for a few years, but have typically been big and bulky. Ampy is much smaller and fashionable enough to wear around.  Read More

Researchers from Northwestern University and the University of Illinois at Urbana-Champaign have developed a health monitor capable of tracking heart and skin condition while worn discretely on the skin. Measuring around 5 cm squared (0.8 in sq), the patch is designed to be inconspicuous and alert the user to conditions ranging from dry skin to cardiovascular problems.  Read More
