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......»»
In a desert seared by climate change, burrowers fare better than birds
In the arid Mojave Desert, small burrowing mammals like the cactus mouse, the kangaroo rat and the white-tailed antelope squirrel are weathering the hotter, drier conditions triggered by climate change much better than their winged counterparts, find.....»»
Deforestation is stressing mammals out
Lots of us are feeling pretty anxious about the destruction of the natural world. It turns out, humans aren't the only ones stressing out—by analyzing hormones that accumulate in fur, researchers found that rodents and marsupials living in smaller.....»»
More mammals are being struck by aircraft each year
Investigators have published a global review of mammal strikes with aircraft, noting that events have been increasing by up to 68% annually. More mammals were struck during the landing phase of an aircraft's rotation than any other phase, according t.....»»
After soaring above $23B, Qualtrics’ founder and CEO reflect on a stellar debut
Amidst the sturm und drang of l'affaire GameStop, the cloud software vendor received a warm welcome from public investors. Amidst all of the the sturm und drang of l’affaire GameStop, Qualtrics went public today. After pricing its sto.....»»
Marine heatwaves becoming more intense, more frequent
When thick, the surface layer of the ocean acts as a buffer to extreme marine heating—but a new study from the University of Colorado Boulder shows this "mixed layer" is becoming shallower each year. The thinner it becomes, the easier it is to warm.....»»
Harnessing the power of AI to understand warm dense matter
The study of warm dense matter helps us understand what is going on inside giant planets, brown dwarfs, and neutron stars. However, this state of matter, which exhibits properties of both solids and plasmas, does not occur naturally on Earth. It can.....»»
Squeeze it like toothpaste: The flexible brain of marsupial mammals
Being stretchy and squeezable may be the key to finding space for the brain in mammals, including humans......»»
Recovery of ovarian function in infertile mammals lacking gonadotropin release
Gonadotropins are any hormones that are released from the anterior pituitary to stimulate the gonads, or sex glands, to carry out their reproductive functions. The gonadotropin-releasing hormone (GnRH) is therefore fundamental for mammalian reproduct.....»»
How did forelimb function change as vertebrates acquired limbs and moved onto land?
When tetrapods (four-limbed vertebrates) began to move from water to land roughly 390 million years ago it set in motion the rise of lizards, birds, mammals, and all land animals that exist today, including humans and some aquatic vertebrates such as.....»»
As oceans warm, large fish struggle
Warming ocean waters could reduce the ability of fish, especially large ones, to extract the oxygen they need from their environment. Animals require oxygen to generate energy for movement, growth and reproduction. In a recent paper in the Proceeding.....»»

Eating omega-3 fat helps hibernating Arctic ground squirrels warm up during deep cold
By feeding arctic ground squirrels special diets, researchers have found that omega-3 fatty acids, common in flax seed and fish oil, help keep the animals warmer in deep hibernation......»»
Foraging humans, mammals and birds who live in the same place behave similarly
Foraging humans find food, reproduce, share parenting, and even organize their social groups in similar ways as surrounding mammal and bird species, depending on where they live in the world, new research has found......»»
A robot made of ice could adapt and repair itself on other worlds
Some of the most tantalizing targets in space exploration are frozen ice worlds. Take Jupiter's moon Europa, for instance. Its warm, salty subsurface ocean is buried under a moon-wide sheet of ice. What's the best way to explore it?.....»»
Future too warm for baby sharks
New research has found as climate change causes the world's oceans to warm, baby sharks are born smaller, exhausted, undernourished and into environments that are already difficult for them to survive in......»»
Researchers propose a framework for evaluating the impacts of climate change on California"s water and energy systems
As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand will intensify. But water and energy are inextricably linked. For instance, nearly a fifth of California's energy goes toward water-related act.....»»
Climate Change Is Turning Cities Into Ovens
A new model estimates that by 2100, cities across the world could warm as much as 4.4 degrees Celsius. It’s a deadly consequence of the “heat island” effect......»»
New work provides insight into the relationship between complexity and diversity
Most forms of life—species of mammals, birds, plants, reptiles, amphibians, etc.—are most diverse at Earth's equator and least diverse at the poles. This distribution is called the latitudinal gradient of biodiversity......»»
Finger pointed at poachers after rare lynx killed in France
A lynx, one of Europe's rarest mammals, has been found shot dead in eastern France in a suspected killing by poachers, local officials said Tuesday......»»
Drought of the century in the Middle Ages—with parallels to climate change today?
The transition from the Medieval Warm Period to the Little Ice Age was apparently accompanied by severe droughts between 1302 and 1307 in Europe; this preceded the wet and cold phase of the 1310s and the resulting great famine of 1315-21. In the jour.....»»
