Helium: Not so super after all

As a gas, helium glows yellow-pink when an electric current is added. Scientists recently reported that they’d made a mistake in a 2004 study that found the element was a supersolid. Turns out helium as a solid isn’t so super. Caption: Pslawinski

An exciting discovery in physics turns out to be merely a case of mistaken identity

No more bubble trouble

Bottlenose dolphins can tell the difference between noisy echoes bounced off of bubbles and other echoes, including those bounced off of prey. Now scientists have figured out a way to tell apart the noises, too. Credit: Emma Jugovich, NOAA
