Mar. 4, 2024 You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if ...
Mar. 1, 2024 Researchers succeed at generating 3D visualizations of chloroplasts' copying ...
Mar. 1, 2024 An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be ...
Mar. 1, 2024 Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal ...
Feb. 29, 2024 A new paper examines the possible effects of two properties of receiver playing fields documented in studies of animal psychology -- habituation and neural adaptation -- on the efficacy of mate ...
Feb. 29, 2024 Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, ...
Feb. 29, 2024 Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. ...
Feb. 29, 2024 Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of ...
Feb. 28, 2024 A genetic change in our ancient ancestors may partly explain why humans don't have tails like ...
Feb. 27, 2024 Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex ...
Feb. 26, 2024 Researchers have shown that inedible species of butterfly that mimic each others' color patterns have also evolved similar flight behaviors to warn predators and avoid being ...
Feb. 22, 2024 The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers ...
Feb. 22, 2024 More than 100 million years ago, the ancestors of the first snakes were small lizards that lived alongside other small, nondescript lizards in the shadow of the ...
Feb. 22, 2024 Researchers have uncovered a key link between the spread of antibiotic resistance genes and the evolution of resistance to new drugs in certain pathogens. Bacteria exposed to higher levels of ...
Feb. 21, 2024 Weedy rice is an agricultural pest with a global economic impact. It is an aggressive weed that outcompetes cultivated rice and causes billions of dollars in yield losses worldwide. A study offers ...
Feb. 21, 2024 Comparison of over 200 high-quality butterfly and moth genomes reveals key insights into their biology, evolution and diversification over the last 250 million years, as well as clues for ...
Feb. 21, 2024 The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling ...
Feb. 20, 2024 Common pool resources comprise around 65 percent of Earth's surface and vast tracts of the ocean. While examples of successful governance of these resources exist, the circumstances and ...
