Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.

Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.

Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilization. Research reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.

The Celtic culture of the pre-Roman Iron Age in Western and Central Europe has left numerous traces to this day, not least in the form of enormous burial mounds and spectacular archaeological artifacts. Despite this rich legacy, much about this civilization remains hidden from us.

Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.

Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Like eyeglasses that darken to provide sun protection, the optical properties of these transparent films can be tuned with electricity to block out solar heat and light. Now, researchers report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating red.

Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.

According to a paper, climate and weather predictions of increased rainfall will lead to an exponential expansion of land-locked lakes on the Tibetan Plateau, resulting in major land loss and related economic, environmental and climatic impacts.

The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.

Short but severe episodes of flooding from hurricanes in Texas and Florida triggered a nationwide increase in flood insurance sign-ups depending on how socially connected a county was to the flooded counties.

The discovery of thousands of stone artefacts and animal bones in a deep cave in Timor Island has led archaeologists to reassess the route that early humans took to reach Australia. Researchers dated and analysed the artefacts and sediment at the Laili rock shelter in central-north Timor-Leste, north of Australia, to pinpoint the arrival of the colonists.

A new study found evidence that Indigenous groups in the Pacific Northwest were intentionally harvesting edible camas bulbs at optimal stages of the plant's maturation as far back as 3,500 years ago.

The analysis of fat traces in over one hundred pottery vessels reveals deep changes in food consumption and preparation by communities living in central Germany between the Early Neolithic and the Late Bronze Age, as well as in their relation with innovations in pottery styles and decorations. In a groundbreaking study, researchers identified a generalized inclusion of dairy products in prehistoric diets, a preference in consuming pork with the arrival of communities from the Eurasian Steppe, and the importance of dairy products in funeral rites. Central Germany was a key region for the emergence of great prehistoric cultures, such as the Linear Pottery Culture, the Corded Ware Culture, the Bell Beaker populations and the Unetice Culture, one of the first state societies in Europe.

Researchers show that nocturnal heat significantly increases the risk of stroke. The findings can contribute to the development of preventive measures: With them, the population can better protect themselves against the risks of climate change with increasingly frequent hot nights. In addition, knowledge of the consequences of hot nights can improve patient care.

Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.

A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.

From the small ossicones on a giraffe to the gigantic antlers of a male moose -- which can grow as wide as a car -- the headgear of ruminant hooved mammals is extremely diverse, and new research suggests that despite the physical differences, fundamental aspects of these bony adaptations likely evolved from a common ancestor.
