New Zealand is one of only a few island nations that could continue to produce enough food to feed its population in a nuclear winter, researchers have found.
Surprises in sea turtle genes could help them adapt to a rapidly changing world
Around 100 million years ago, a group of land-dwelling turtles took to the oceans, eventually evolving into the sea turtles that we know today. However, the genetic foundations that have enabled them to thrive in oceans throughout the world have remained largely unknown.
Changing Climate Conditions Likely Facilitated Early Human Migration to the Americas at Key Intervals, Research Suggests
Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper published today in the Proceedings of the National Academy of Sciences shows.
Small Isolated Wetlands Are Pollution-Catching Powerhouses
Small isolated wetlands that are full for only part of the year are often the first to be removed for development or agriculture, but a new study shows that they can be twice as effective in protecting downstream lake or river ecosystems than if they were connected to them.
Devastating cost of future coastal flooding for many developing nations predicted in new study
New global modelling predicts the devastating socioeconomic impacts of future extreme coastal flooding for developing nations caused by climate change, with Asia, West Africa and Egypt facing severe costs in the coming decades.
Pacific Northwest Heat Dome Tree Damage More About Temperature Than Drought, Scientists Say
Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, Oregon State University researchers say.
A faster, more accurate 3D modelling tool recreates a landscape’s digital twin down to the pixel level
Researchers have developed a new technique that can help create high-quality, accurate 3D models of large-scale landscapes -- essentially, digital replicas of the real world. The framework reconstructs the geometry, structure and appearance of an area using highly detailed images taken by aircraft typically flying higher than 30,000 feet. These...
Why icicles are rippled
Winter is coming to an end; the last nights of below zero temperatures are here. In the morning, one still spots the occasional icicle on a gutter or car bumper. When you look at these icicles carefully, you may notice that they show a characteristic pattern of ripples -- always...
A fossil fruit from California shows ancestors of coffee and potatoes survived cataclysm that killed the dinosaurs
The discovery of an 80-million-year-old fossil plant pushes back the known origins of lamiids to the Cretaceous, extending the record of nearly 40,000 species of flowering plants including modern-day staple crops like coffee, tomatoes, potatoes and mint.
Antarctica’s Ocean Brightens Clouds
The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a study published today in Atmospheric Chemistry and Physics.
