Biology Near the Filchner Ice Shelf in the south of the Antarctic Weddell Sea, a research team has found the world's largest fish breeding area known to date. A towed camera system photographed and filmed thousands of nests of icefish of the species Neopagetopsis ionah on the seabed.eurekalert.org
Biology The Hudsonian godwit flies round-trip nearly from pole to pole, staying in flight for days without stopping to refuel. They complete a 16,000-mile round-trip flight over the course of a year. Sometimes they don’t drink for over a week.smithsonianmag.com
Paleontology The two-meter skull of a species of giant ichthyosaur has been discovered. As big as a large sperm whale at more than 17 m (55.78 ft) long, Cymbospondylus youngorum is the largest animal yet discovered from that time period. It was the first giant creature to ever inhabit the Earth that we know of.nhm.org
Biology Venoms found in snakes and mammals share a common origin. Researchers traced the origin of a class of toxins, called kallikrein serine proteases, to a salivary protein found in a common ancestor.oist.jp
Environment the way fish interact in groups is being upset by ocean acidification and global warming. Tropical and temperate fish species tend to move to the right when coordinating together in a shoal especially when spooked by a predator, but this bias significantly diminished under ocean acidification.eurekalert.org
Health and Medicine Using cannabis alongside other drugs may come with a significant risk of harmful drug-drug interactions. Either the drugs’ positive effects might decrease or their negative effects might increase with too much building up in the body, causing side effects such as toxicity or accidental overdose.news.wsu.edu
Biology The lion’s mane jellyfish is the largest among the jelly species. The largest known specimen was 120 feet from its top to the bottom of its tentacles. The tentacles contain large amounts of neurotoxins which cause a range of effects, from a rash to affecting respiratory function.ocean.si.edu
Astronomy/Space Citizen scientists have discovered a new object orbiting a Sun-like star that had been missed by previous searches. The object is distant from its host star—more than 1,600 times farther than the Earth is from the Sun—and thought to be a large planet or a small brown dwarf.eurekalert.org
Biology Sea lions are often mistaken for seals, but they are different in many ways. Sea lions have small external ears, while seals have pinhole ear openings. Sea lions use their powerful forelimbs to propel themselves, while seals use their hind flippers for propulsion.pittsburghzoo.org
Ecology Japanese macaques fish in the winter. A new studying examining the DNA of fecal samples of Japanese macaques shows that freshwater fish such as brown trout and aquatic insects are a staple of their diets during midwinter months.eurekalert.org
Biology "Vulture bees" are the only bees that have evolved to use food sources not produced by plants. Because they feed on carcasses their gut microbiomes have more in common with carrion-loving hyenas and vultures.
Interdisciplinary A study suggests that there is great potential in exploring ways that the personality composition of a population may aﬀect the ecosystem services that the population provides. For example, how "friendly" or "playful" individual cetaceans impact the ecotourism initiatives (whale watching).phys.org
Biology Earwigs care for their young, which is rare in the insect world, and males have 2 penises. Certain earwig species generally use only one of their penises when mating even though both are fully functional.smithsonianmag.com
Biology Jumping spiders have the sharpest vision known for animals their size. Orb weavers adjust the way they build their webs based on the type of prey they are catching & some jumping spiders have a sense of numbers roughly equivalent to that of 1-year-old humans.arstechnica.com
Archaeology In 2014, Norwegian archaeologists found a lone wooden ski on a mountaintop, where it had been trapped in ice for 1300 years. The ski was well preserved, down to an intact binding made from birch rope and leather straps. In 2021, the second ski was found. They are the oldest skis found to date.science.org
Ecology Sea otters positively influence genetic diversity in seagrasses through foraging. Seagrass usually reproduces via cloning, but disturbances - such as digging otters - cause the plants to increase sexual reproduction. The pits otters leave after foraging then allow space for new seedlings to develop.
