Acoustic levitation? It works like this: Two horns vibrate at 22,000 times a second, firing sound waves into a pocket of air between the two devices. “When these two waves interact, you’ll get what’s called a standing wave, so they’ll cancel in places and they’ll reinforce in others to create nodes and antinodes,” says physicist Chris Benmore, of the Argonne National Laboratory in Illinois. “Those particular places where they cancel, you put an object in and you can levitate it.”

How we know where we are and how we navigate from one place to another. The discovery of grid cells – the brain’s inner GPS – led to May-Britt Moser receiving the 2014 Nobel Prize in Physiology or Medicine.

Albatrosses strapped with sensors are spying on illegal fishing boats. They can travel vast distances and are attracted to the vessels.

There is compelling evidence that African penguins have speech patterns similar to ours? In which language again?

Pneumonia can be prevented with vaccines and easily treated with low-cost antibiotics. So why were 800,000 children left to die from the disease last year?

Supercells (a cyclone type) produce severe weather, including damaging winds, very large hail, and sometimes even tornadoes. What makes them unique from all other thunderstorms is that supercells contain a deep and persistent rotating updraft called a mesocyclone. In some cases, they can last for several hours.
