Mammals were not the first to be warm-blooded
Endothermy, or warm-bloodedness, is the ability of mammals and birds to produce their own body heat and control their body temperature......»»
Slower metabolism of warm-blooded animals on islands correlated with higher risk of anthropogenic extinction
A multi-institutional team of zoologists and animal behavioral specialists in China and Germany has found an association between the slower metabolism of island-dwelling, warm-blooded animals and an increased risk of anthropogenic extinction......»»
Evidence for butchery of giant armadillo-like mammals in Argentina 21,000 years ago
Cut marks on fossils could be evidence of humans exploiting large mammals in Argentina more than 20,000 years ago, according to a study published July 17, 2024 in the open-access journal PLOS ONE by Mariano Del Papa of National University of La Plata.....»»
Researchers predict fewer, pricier strawberries as temperatures warm
Strawberries could be fewer and more expensive because of higher temperatures caused by climate change, according to research from the University of Waterloo......»»
Earth system scientists discover missing piece in climate models
As the planet continues to warm due to human-driven climate change, accurate computer climate models will be key in helping illuminate exactly how the climate will continue to be altered in the years ahead......»»
The return of Bladerunner the humpback and Spilt Fin the killer whale—a cautionary tale about seafaring vessels
In the past few days, two well known survivors of the battle between marine mammals and vessels have been spotted in Australian waters. I'm talking about Bladerunner the humpback and Split Fin the killer whale. Both have become famous for the massive.....»»
Evolutionary biologists investigate how plant cold specialists can adapt to the environment
Plant cold specialists like the spoonworts have adapted well to the cold climates of the Ice Ages. As cold and warm periods alternated, they developed a number of species that also resulted in a proliferation of the genome......»»
A stealth fungus has decimated North American bats, but scientists may be a step closer to treating white-nose syndrome
An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, wh.....»»
Mars likely had cold and icy past, new study finds
The question of whether Mars ever supported life has captivated the imagination of scientists and the public for decades. Central to the discovery is gaining insight into the past climate of Earth's neighbor: Was the planet warm and wet, with seas an.....»»
Surfing NASA"s internet of animals: Satellites study ocean wildlife
Anchoring the boat in a sandbar, research scientist Morgan Gilmour steps into the shallows and is immediately surrounded by sharks. The warm waters around the tropical island act as a reef shark nursery, and these baby biters are curious about the ne.....»»
Why Hurricane Beryl Underwent Unprecedented Rapid Intensification
Hurricane Beryl, the earliest Category 5 storm in the Atlantic, exploded in strength unusually early in its development, fueled by exceptionally warm ocean waters.....»»
Egg cell maintenance: Long-lived proteins may be essential for fertility
Female mammals—including humans—are born with all of their egg cells. Of a woman's one to two million egg cells, about 400 mature before menopause and can be fertilized. Some egg cells therefore survive for several decades—and need to remain fu.....»»
Features of H5N1 influenza viruses in dairy cows may facilitate infection, transmission in mammals
A series of experiments with highly pathogenic H5N1 avian influenza (HPAI H5N1) viruses circulating in infected U.S. dairy cattle found that viruses derived from lactating dairy cattle induced severe disease in mice and ferrets when administered via.....»»
Pregnant fish can also get "baby brain," but not the way that mammals do
New research reveals that pregnancy-related brain impairment is present in live-bearing fish, but instead of affecting learning and memory as expected from similar research on mammals, it appears to have a stronger impact on decision-making and senso.....»»
Clues to mysterious disappearance of North America"s large mammals 50,000 years ago found within ancient bone collagen
50,000 years ago, North America was ruled by megafauna. Lumbering mammoths roamed the tundra, while forests were home to towering mastodons, fierce saber-toothed tigers and enormous wolves. Bison and extraordinarily tall camels moved in herds across.....»»
Scientists pit primates against smaller-brained mammals to find out who is the smartest forager
Primates, including humans, have larger brains than most other mammals, but why? Scientists searching for the answer have long followed a trail pointing to diet—specifically fruit—as the reason for why primates evolved larger brains......»»
Dinosaurs needed to be cold enough that being warm-blooded mattered
Two groups of dinosaurs moved to cooler climes during a period of climate change. Enlarge / Later theropods had multiple adaptations to varied temperatures. (credit: SCIEPRO/SCIENCE PHOTO LIBRARY) Dinosaurs were once ass.....»»
Exceptionally early heat wave hits Finland
Finland has been experiencing unusually warm weather this May, prompting the Meteorological Institute to issue a heat warning on Monday......»»
US dairy cows are tip of the iceberg as bird flu spreads in mammals globally, says ecologist
Health authorities are working to gather information on the spread of the H5N1 virus, or bird flu, in U.S. dairy cows—the first confirmation of the virus in cattle......»»
EarthCARE satellite to probe how clouds affect climate
Will clouds help cool or warm our world in the years ahead? The EarthCARE satellite will soon blast off on a mission to find out, aiming to investigate what role clouds could play in the fight against climate change......»»
Finding the beat of collective animal motion: Scientists show reciprocity is key to driving coordinated movements
Across nature, animals from swarming insects to herding mammals can organize into seemingly choreographed motion. Over the last two decades, scientists have discovered that these coordinated movements arise from each animal following simple rules abo.....»»
