A research team led by Professor Kang Taek Lee in the Department of Energy Science and Engineering developed electrode material for a new form of high-performance Solid Oxide Fuel Cell (SOFC). Since SOFC, which generates electricity by reacting hydrogen (fuel) with oxygen in the air, emits only water after reaction, is ecofriendly, and has little restrictions in installation place, it is drawing limelight as a new and renewable energy technology that is appropriate for distributed generation . However, it has been difficult to obtain stable supply due to the rapid performance decline of electrode generating power amidst sudden stop and the suspension of fuel supply.

Scientists study the energetic particles behind stunning light show. Scientists have quantitatively confirmed how energetic an auroral breakup can be. Using a combination of cutting-edge ground-based technology and new space-borne observations, they have demonstrated the essential role of an auroral breakup in ionizing the deep atmosphere. The research furthers our understanding of one of the most visually stunning natural phenomena.

Auroras, also known as Northern or Southern lights depending on whether they occur near the North or South Pole, are natural displa...

Auroras, also known as Northern or Southern lights depending on whether they occur near the North or South Pole, are natural displays of light in the Earth’s sky. Typically these lights are dimly present at night...

An MIT-led research team has developed a drug capsule that could be used to deliver oral doses of insulin, potentially replacing the injections that people with type 2 diabetes have to give themselves every day.

About the size of a blueberry, the capsule contains a small needle made of compressed insulin, which is injected after the capsule reaches the stomach. In tests in animals, the researchers showed that they could deliver enough insulin to lower blood sugar to levels comparable to those produced by injections given through skin. They also demonstrated that the device can be adapted to deliver other protein drugs.

“We are really hopeful that this new ty...
