Study reveals that bats experience hearing loss in old age

Many mammals suffer hearing loss in old age, but bats were thought to be immune to this phenomenon because of the importance of hearing for echolocation. However, researchers in Israel have discovered that bats lose their ...

What do the elements sound like?

In chemistry, we have He, Fe and Ca—but what about do, re and mi? Hauntingly beautiful melodies aren't the first things that come to mind when looking at the periodic table of the elements. However, using a technique called ...

Galaxy changes classification as jet changes direction

A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the ...

Scientists develop new lithium niobate laser technology

Scientists at EPFL and IBM have developed a new type of laser that could have a significant impact on optical ranging technology. The laser is based on a material called lithium niobate, often used in the field of optical ...

Light and milling balls for greener chemical processes

Light-driven chemical reactions have usually been conducted with large amounts of solvents that are often toxic. By combining them with mechanical energy in ball mills, Professor Lars Borchardt's team at the Chair of Inorganic ...
