Bone needles found at the 12,900-year-old site of La Prele in Wyoming, the United States, were produced from the bones of foxes; hares; and felids such as bobcats, mountain lions, lynx and possibly even the now-extinct American cheetah; these animal bones were used by the early Paleoindian foragers at La Prele because they were scaled

Paleontologists from Sweden and Poland have examined hundreds of fossilized samples of feces and vomit from the Polish Basin in central Europe to reconstruct the rise of the dinosaurs to become the dominant players in Earth’s ancient ecosystems.

Nociceptors are receptors that detect injurious stimuli and are necessary to convey such information from the periphery to the central nervous system. Crustaceans, such as shore crabs, are widely used in science and aquaculture. Understanding whether they can experience pain is essential for improving their welfare. One key criterion for assessing pain is the presence

Several of the icy moons in the Jupiter and Saturn systems appear to possess internal liquid water oceans. Our knowledge of the Uranian moons is more limited but a future tour of the Uranus system has the potential to detect subsurface oceans. Planning for this requires an understanding of how the moons’ internal structures —

The sharp resolution of Webb’s Mid-Infrared Instrument (MIRI) brings into focus details of the Sombrero galaxy’s outer ring, providing insights into how the dust is distributed. This Webb image shows the Sombrero galaxy. Image credit: NASA / ESA / CSA / STScI. The Sombrero galaxy is located approximately 28 million light-years away in the constellation

The Vikings played a preeminent role in the peopling of the North Atlantic, and one might expect populations that were founded by them to be genetically similar and homogeneous. New research suggests that the Icelandic and Faroese populations had distinguishably different founding fathers. The results are consistent with the scenario that the Faroese male population

The world’s thinnest spaghetti is just 372 nm across — about 200 times thinner than a human hair. Britton et al. used a scanning electron microscope, scanning the mat with a focused beam of electrons and creating an image based on the pattern of electrons that are deflected or knocked-off; each individual strand is too
