Newly discovered hair cells on squid may offer clues to understanding hearing loss in humans‎

Scientists have known for years that squid have cells with bundles of tiny, hairlike protrusions on their heads and arms, similar to those buried deep inside the human ear that allow us to hear. Now, researchers at Case Western Reserve University have discovered that these animals have hundreds more of these cells, called hair cells, lining the entire surface of their bodies. The discovery may provide researchers with an unprecedented window into how humans use—and lose—their hearing.

A short breath extends the mating calls of male tokay geckos‎

Tokay geckos (Gekko gecko), large and mostly nocturnal geckos native to parts of Asia, are among the few nonbird reptiles that make sounds to attract potential mates, defend their territory and signal distress. Male tokay geckos' calls typically begin with quieter rattles, followed by louder two-part sounds that can sound like "ge-ko" or "to-kay."

Milky Way may have begun as thousands of galaxies, new simulations suggest‎

In the early days of the universe, our home looked very different from how it does today. Back then, the region in our universe that would eventually become our Milky Way neighborhood was a collection of thousands of smaller galaxies—some pumping out tons of new stars, others filled only with gas or littered with dead stars and black holes.

Energy production, virus defenses and toxin loading emerge as vulnerabilities in resistant bacteria‎

Antimicrobial resistance is one of the world's top public health threats. Often termed a silent pandemic, antimicrobial-resistant bacteria have caused millions of deaths annually. If left unchecked, the number of deaths attributed to antimicrobial-resistant bacteria is expected to increase to 10 million a year by 2050, according to estimates by the World Health Organization.

French deportation rulings show how judges navigate conflicting rules on forced removal‎

European deportation practices are governed by a complex web of European, national and human rights law, says the author of a paper published in the International Journal of Migration and Border Studies. Based on 100,000 French court cases, the study shows that national courts play a central role in determining whether individuals can be removed.

Cooper pairs found above superconducting critical temperature in pair density waves‎

Physicists with the University of Illinois Urbana-Champaign's Grainger College of Engineering have identified a new form of superconducting behavior. Experiments on the metal uranium ditelluride reveal that Cooper pairs, the composite electron units responsible for superconductivity, can organize into nonuniform patterns that exist even when the main superconducting phase is absent.
