Brazil’s National museum burned, destroying priceless historical and scientific artifacts. (Credit: A.PAES/shutterstock) A version of this article originally appeared on The Conversation. We now know what history going up in flames looks like. On Sept. 2, the National Museum of Brazil lit up Rio de Janeiro’s night sky. Perhaps started by an errant paper hot air balloon landing on the roof or a short circuit in a laboratory, the fire gutted the historic 200-year-old building. Likely ...read more

The design on the housing of ATERUI II represents an artist’s (Jun Kosaka) contemporary take on traditional Japanese block style lettering, spelling out the supercomputer’s nickname.(Credit: NAOJ) One of the long-standing problems in astronomy is that you cannot hold the Sun. You can’t jump into it or examine it under a microscope. Nor can astronomers go back in time to witness the Big Bang or even ...read more

Stegodyphus dumicola spiders. (Credit: Wikimedia Commons) A bold or aggressive person can change the dynamic of a group. That happens in spider colonies, too. In a study published this week in Proceedings of the Royal Society B, researchers show that bold spiders can change the behavior of other spiders. The meek spiders start copying the behavior, something that can both help and potentially harm the colony. Copycat Spiders Researchers collected colonies of Stegodyphus dumicola in South Afric ...read more

'Robat' The Robot Explores Using Echolocation

Posted on Categories Discover Magazine

Robat can’t fly. But the autonomous robot can use echolocation to survey its environment. (Robat is a fully-autonomous bat-like terrestrial robot that uses echolocation to navigate its environment. (Credit: Itamar Eliakim) Bats can fly nimbly at night in large part because echolocation helps them “see” in the dark. Now researchers say they have created the first robot to use echolocation like a bat to help it explore its surroundings fully autonomously. Bats echolocate by emi ...read more

Researchers witness a one billion year old galaxy blow molecular gas to its outskirts to avoid an overproduction of stars. Credit: ALMA (ESO/NAOJ/NRAO), Spilker; NRAO/AUI/NSF, S. Dagnello; AURA/NSF The years following the Big Bang were undoubtedly an exciting time in our cosmological history, with galaxies birthing hundreds or even thousands of hot new stars each year. But despite rapid star formation being exhilarating, it’s far from sustainable. Star Formation Secrets Re ...read more
