January 6 Wasn't a Riot. It Was War.
In the days and weeks after the storming of the U.S. Capitol on January 6, 2021, commentators and media outlets grappled with the question of what to call that event. Language is sticky; it clarifies and obfuscates the truth depending on who's wielding it. January 6 was described as or likened to a " riot ," a " tourist visit ," an " insurrection ," a " peaceful protest ," and a " coup attempt ."

Ivory poaching has led to evolution of tuskless elephants, study finds
Researchers say findings in Mozambique demonstrate impact of human interference in nature Ivory poaching over decades has led to the evolution of tuskless elephants, researchers have found, proving that humans are "literally changing the anatomy" of wild animals.

New Brain Implant Lets Blind Patient See Without Eyes
Scientists in Spain have implanted a blind patient that allowed a blind patient to see by directly stimulating her brain's visual cortex.

Cochlear outer hair cell electromotility enhances organ of Corti motion on a cycle-by-cycle basis at high frequencies in vivo [Neuroscience]

In 1969, English physicist Roger Penrose discovered a property which would later allow for a long-awaited link between thermodynamics, and the far stranger mechanics of black holes. Through new analysis published in EPJ H, Carla Rodrigues Almeida, based at the University of São Paulo, Brazil, sheds new light on Penrose's motivations and methods, and explores their historical influence on the groun

COVID-19 vaccination strategies: When is one dose better than two?
While most of the COVID-19 vaccines are designed as a two-dose regimen, some countries have prioritized vaccinating as many people as possible with a single dose before giving out an additional dose. In a new study, researchers illustrate the conditions under which a "prime first" vaccine campaign is most effective at stopping the spread of the COVID-19 virus.

While most people in the U.S. may think of bumble bees as the standard yellow and black variety, there are an estimated 260 bee species that sport about 400 different color patterns. One reason many people associate bumble bees with distinct colors is because evolution can influence multiple bee species to share similar color patterns in specific geographic regions, which scientists call mimicry.
