The potentially lifesaving technique uses nanotechnology and shortwave infrared light to reveal small cancerous tumors and cardiovascular lesions deep inside the body.

Since their appearance over 150 million years ago, feather shafts (rachises) have evolved to be some of the lightest, strongest and most fatigue resistant natural structures.

Glass hangs in a metastable state in which the energy of the system is higher than the lowest-energy state the system could assume, a crystalline state. But its state is stable enough at room temperature to last a human lifetime.

The battery will also have a longer lifespan of over 20 years. Expected to be the next big thing in battery technology, this breakthrough has a wide-ranging impact on many industries, especially for electric vehicles which are currently inhibited by long recharge times of over 4 hours and the limited lifespan of batteries.

Researchers report that decaffeinated coffee drinking may benefit liver health. Results show that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes.

Results show that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes. This suggests that chemical compounds in coffee other than caffeine may help protect the liver.

Helped by fluorescent molecules the Nobel Laureates in Chemistry 2014 ingeniously circumvented this limitation. Their ground-breaking work has brought optical microscopy into the nanodimension.

Moser for their discoveries of cells that constitute a positioning system in the brain. The discoveries have solved a problem that has occupied philosophers and scientists for centuries -- how does the brain create a map of the space surrounding us and how can we navigate our way through a complex environment?

However, the large charging overpotential remains a challenge due to the difficulty in electrochemically oxidizing the insulating ​lithium peroxide. Recently, a redox shuttle has been introduced into the electrolyte to chemically oxidize ​lithium peroxide. Here, we report the use of a ​triiodide/iodide redox shuttle to couple a built-in dye-sensitized ​titanium dioxide photoelectrode with the oxygen electrode for the photoassisted charging of a lithium–oxygen battery. On charging under illumination, ​triiodide ions are generated on the photoelectrode, and subsequently oxidize ​lithium peroxide. Due to the contribution of the photovoltage, the charging overpotential is greatly reduced. The use of a redox shuttle to couple a photoelectrode and an oxygen electrode offers a unique... less
