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......»»
After slow start, NOAA predicts rest of hurricane season to be “above normal”
El Niño is developing slower than anticipated and the ocean is extremely warm. Enlarge / In Florida, parts of the Sanibel Causeway to Sanibel Island are washed away, along with sections of the bridge to the island, after Hurrica.....»»
Microplastics found embedded in tissues of whales and dolphins
Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student's study of ocean microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics ca.....»»
New paleoaltimetry research questions assumptions about the formation of the Himalayas
Mountain ranges play a key role in global climate, altering weather and shaping the flora and fauna that inhabit their slopes and the valleys below. As warm air rises windward grades and cools, moisture condenses into rain and snow. On the leeward si.....»»
New SARS-CoV-2 variant gains dominance in US amid mild summer COVID wave
Absolute numbers are low, but several indicators show pandemic virus is on the rise. Enlarge (credit: Getty | Thomas Trutschel) For a fourth consecutive summer, COVID-19 is on the rise, though this year's warm-weather wa.....»»
Gene grants powerful resistance to resurging plant disease
While wrapping oneself in 100% Egyptian cotton bedsheets is a delightful luxury on a warm summer night, cotton provides much more than breathable, soft fabric. In addition to textiles, the cotton plant is grown for food, fuel, and daily-use consumer.....»»
Winter storms over Labrador Sea influence Gulf Stream system
The Gulf Stream, which brings warm water from the Gulf of Mexico to Europe and keeps the climate mild, is only part of a larger system of oceanic currents called the Atlantic Meridional Overturning Circulation, or AMOC for short. It runs through the.....»»
Munching Bugs Gave the First Mammals an Edge
Early mammals got ahead by eating insects.....»»
Amsterdam builds massive bike garage resembling an Apple Store
Bicycle-loving Amsterdam has created an underground bike parking garage that looks directly inspired by the design language of the Apple Store.The Apple Store's modern aesthetic relies on clean lines and lots of wood on display, producing a warm and.....»»
Research team identifies human odorant receptor for "horse stable" odor, with implications for food testing
Para-cresol is an aromatic compound with a strong horse stable-like odor. It contributes to the off-flavor of some foods, but it is also detectable as a characteristic odorant in whiskey and tobacco, as well as in the urine of various mammals......»»
Do video doorbells work in extreme heat?
While video doorbells can work in warm weather, they start to shut down if the temperature gets too high. Here's a look at the thresholds for popular brands......»»
Chinese scientists complete a concept study for a 6-meter space telescope to find habitable exoplanets
We have discovered more than 5,400 planets in the universe. These worlds range from hot jovians that closely orbit their star to warm ocean worlds to cold gas giants. While we know they are there, we don't know much about them. Characteristics such a.....»»
Human presence found to influence overall mammal abundance in northern Myanmar
Understanding the factors that influence large mammal habitat use and their spatio-temporal response to human disturbance plays a crucial role in wildlife conservation and management. However, this knowledge is still limited for most mammals......»»
Fossil skulls alone cannot predict if animal was warm blooded, study finds
The ability of most mammals to maintain a relatively constant and high body temperature is considered a key adaptation, enabling them to successfully colonize new habitats and harsh environments. Eager to determine how this ability evolved, some scie.....»»
Generation of a human haploid neural stem cell line for genome-wide genetic screening
Haploid embryonic stem cells (haESCs) have been established in many species. Differentiated haploid cell line types in mammals are lacking due to spontaneous diploidization during differentiation that compromises lineage-specific screens......»»
Global warming will cause more multiyear La Niña events, study finds
Southern Oscillation (ENSO) is the Earth's most consequential interannual climate fluctuation. Alternating irregularly between warm El Niño and cold La Niña phases, it brings shifts in ocean surface temperature and disrupts wind and rainfall patter.....»»
Better energy harvesting with "law-breaking" device
If you take an object and set it out in the sun, it will begin to warm up. This is because it is absorbing energy from the sun's rays and converting that energy to heat. If you leave that object outside, it will continue getting warmer, but only to a.....»»
The UK is still not prepared for extreme temperatures—here"s what it should do
While massive heatwaves are affecting southern Europe, China, the US and many other places, it's rainy and not particularly warm in the UK. But that doesn't mean there's no risk of intense heat: on this exact week last year, the UK broke 40°C for th.....»»
How sea-ice anomalies in the Barents–Kara Sea are modulated by the "warm Arctic–cold Eurasia" pattern
"Warm Arctic—cold Eurasia" is one of the most significant patterns of winter climate system changes in the mid-high latitudes of the Northern Hemisphere. In winter 2020/21, this large-scale pattern underwent a significant and intense subseasonal re.....»»
Scientists discover filter-feeding basking sharks are warm-bodied like great whites
Approximately 99.9% of fish and shark species are "cold-blooded," meaning their body tissues generally match the temperature of the water they swim in—but researchers have just discovered the mighty basking shark is a one-in-a-thousand exception. I.....»»
Wild fruits with higher alcohol content found to be more widely dispersed by mammals
A team of researchers from the University of Calgary, Área de Conservación Guanacaste, the University of Exeter and the College of Central Florida has found that wild fruits in Costa Rica with higher alcohol content tend to be spread more widely by.....»»
