For spending their 160 million years of existence mostly hiding in rivers and streams under rocks, Eastern and Ozark hellbenders had done pretty well for themselves.

Today East Asia, and in particular the Hengduan Mountains and other parts of southwestern China, hosts several of Earth's great biodiversity "hotspots." A biodiversity hotspot is where very large numbers of unique species are under threat of extinction, and so are conservation priority areas. However, to understand how best to look after this diversity we need to understand what created it and how it has been maintained before human threats.

More than 7,000 languages are spoken in the world. This linguistic diversity is passed on from one generation to the next, similarly to biological traits. But have language and genes evolved in parallel over the past few thousand years, as Charles Darwin originally thought?

Behind the fences surrounding this 40-square-mile outback of cactus and wiry creosote, the largest remaining population of Mojave desert tortoises was soaking up the morning sun and grazing on a mix of wild greens and flowers.

The Artemis I mission brought Orion on its closest approach to the moon while blasting out on its way to an orbit that will take it farther from the Earth than any previous human-rated spacecraft.

In the past few decades, the use of phase field-modeling equations for mathematical modeling has progressed. Phase separation has been studied extensively in thermodynamics and materials engineering, but the biological field has also begun to take an interest in this phenomenon.

Dust from the dry Puna Plateau in northwestern Argentina was an important source of iron for the nutrient-deficient South Pacific in the last two glacial cycles—especially at the beginning of these cycles. This was the key finding of a study presented in the Proceedings of the National Academy of Sciences journal by a team of researchers led by geochemist Dr. Torben Struve from the University of Oldenburg.

First, the bad news: Nothing is free. Moving the world energy system away from fossil fuels and into renewable sources will generate carbon emissions by itself, as construction of wind turbines, solar panels and other new infrastructure consumes energy—some of it necessarily coming from the fossil fuels we are trying to get rid of. The good news: If this infrastructure can be put on line quickly, those emissions would dramatically decrease, because far more renewable energy early on will mean far less fossil fuel needed to power the changeover.

The complete skeletal remains of a spider monkey—seen as an exotic curiosity in pre-Hispanic Mexico—gives researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers.

High-Q mechanical resonances are desired in many applications. The conventional wisdom relies on minimizing the size of the supporting structure of mechanical resonators, which renders the fabricated mechanical device fragile.

The cell is the basic structural and functional unit of life, with varying sizes, shapes, and densities. There are many different physiological and pathological factors that influence these parameters. It is therefore extremely important for biomedical and pharmaceutical research to study the characteristics of cells.

Preschool children's play involving tablets is less creative and imaginative compared to their play involving physical toys. This is shown in a new study by Uppsala University, and the difference is substantial. The results counter occasional claims that new technology would make children more creative.

Swarms of iridescent Christmas beetles used to mark Australia's summer season every year. But today, they seem as scarce as mixtapes and crochet swimsuits.

The next time you crack your backdoor to let your cat outside for its daily adventure, you may want to think again. For a cat, the outdoors is filled with undesirable potential. Like the risks of catching and transmitting diseases, and the uncontrollable drive to hunt and kill wildlife, which has been shown to reduce native animal populations and degrade biodiversity.

Add the name of Takeoff, a member of the popular rap trio Migos, to the ever-growing list of rappers, recent and past, tragically and violently killed.

QR codes on milk cartons could be used to provide consumers with detailed information on the care and well-being of farm animals reared as livestock.

A team of scientists led by crystallographers from St Petersburg University has succeeded in synthesizing an analog of the Earth's most structurally complex mineral, ewingite, in a laboratory. The findings of the research are published in Materials.

The planet is heating up as greenhouse gas emissions rise, contributing to extreme heat waves and once-unimaginable flooding. Yet despite the risks, countries' policies are not on track to keep global warming in check.

A new light source generates ultrashort infrared pulses at wavelengths around 12µm with previously unattained peak intensity and stability. First experiments in vibrational spectroscopy on water demonstrate the high potential of the system for applications.

Winning the FIFA World Cup significantly increases GDP growth in the two quarters following the competition by up to 0.25 percentage points, according to new research from the University of Surrey.

Two decades after having described a new Anaconda species based on morphological characteristics, a team guided by David Tarknishvili succeeded in extracting DNA from some old, pre-existing tissue samples. They used these to substantiate and verify the specific status of the new species.

On the 81st anniversary of the sinking of the Australian warship HMAS Sydney (II) and the disguised German raider HSK Kormoran following a battle off the coast of Western Australia during WWII, Curtin University has revealed a new large-scale 3D reconstruction from the wreck sites.

Africa's livestock farmers are at the forefront of climate change. Images of parched landscapes littered with the carcasses of starved cattle are becoming all too familiar as droughts increase in frequency and severity. But cattle farming globally is also one of the causes of climate change. The world's three billion or more ruminants—cattle, sheep and goats—produce methane, one of the most potent greenhouse gases, as a by-product of digestion.

It's hard for most people to imagine six feet of snow in one storm, like the Buffalo area saw over the weekend, but such extreme snowfall events occasionally happen along the eastern edges of the Great Lakes.

The COVID-19 pandemic has exacerbated social and economic inequalities between men and women in Canada.
