Large and publicly available astronomical archives open up new possibilities to search for and study small solar system objects such as asteroids and comets. A citizen scientist spotted the main-belt asteroid 2001 SE101 passing in front of the Crab Nebula. Image credit: NASA / ESA / Hubble / M. Thévenot, @AstroMelina. In its 32 years of observations, the NASA/ESA Hubble Space Telescope has produced...
In the 2000s, planetary researchers spotted ghostly, blue-white morning frost on the Martian surface in visible light images from NASA’s Mars Odyssey spacecraft. But using Mars Odyssey’s Thermal Emission Imaging System (THEMIS), the orbiter’s heat-sensitive camera, the frost appeared more widely, including in areas where none was visible. The scientists knew they were looking at frost that...
Despite several important studies, Indigenous fisheries generally receive less attention from scholars and managers than the 17th-20th century capitalist commercial fisheries that decimated many keystone species, including oysters. In new research, archaeologists investigated Indigenous oyster harvest through time in North America and Australia, placing their data in the context of sea level histories...
The newly-identified species of screw palm, named Pandanus estellae, is significant because it provides credible pre-Pleistocene evidence of the genus Pandanus. Reconstruction of Pandanus estellae. Image credit: Alison Douglas. Pandanus is a genus of palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. Commonly known as pandans, screw palms, and screw pines, there...
A team of scientists from Binghamton University, the Amazon Conservatory for Tropical Studies, the California State University Sacramento and the Universidade de Aveiro has documented the prolonged underwater refuge use (over 30 minutes) of Trechalea extensa following pursuit by a perceived threat. While submerged, Trechalea extensa uses a film of air to hide from predators. Image credit: Lindsey...
The flexible, thin-film loudspeaker, developed by MIT researchers, weighs only 2 g, is 120 microns thick, and can generate high-quality sound no matter what surface the film is bonded to. These advantages make it a promising candidate for ubiquitous applications in existing and emerging industrial and commercial scenarios. Han et al. developed an ultra-thin loudspeaker that can turn any rigid surface...
New research highlights the important role of nutrition for the treatment of depression and should inform advice given by clinicians to young men. Young males with a poor diet saw a significant improvement in their symptoms of depression when they switched to a healthy Mediterranean diet.

Scientists have sequenced the genome of a desert dingo (Canis dingo) from a remote region of South Australia and compared it with those of five breeds that span the domestic dog genealogy (boxer, German shepherd dog, basenji, Great Dane, and Labrador retriever) as well as Greenland wolf. Sandy as a 3-year-old; she was found as a 4-week-old puppy in a remote region of South Australia in 2014; subsequent...
The nature of Earth’s earliest crust and crustal processes remains enigmatic due to the almost complete lack of a rock record older than 4 billion years (Hadean Eon) and the scarcity of rocks between 4 and 3.6 billion years (Eoarchean Era). One unresolved question is when mobile-lid tectonics commenced. To study the Hadean, the only direct record is from the mineral zircon, but Hadean zircon is...
