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.
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.
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.
Forest Management Will Have a Stronger Effect Than Climate Change on the Supply of Ecosystem Services
Forests contribute to human well-being by providing a wide variety of ecosystem services to the society.
The Plants Seeking Refuge Across Our Dynamically Changing Planet
Experts from the UK Centre for Ecology & Hydrology (UKCEH) are joining leading scientists from across Europe to provide practical and effective solutions for addressing the global biodiversity crisis.
More Frequent Atmospheric Rivers Hinder Seasonal Recovery of Arctic Sea Ice
The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt.
Rescuing small plastics from the waste stream
As plastic pollution continues to mount, with growing risks to ecosystems and wildlife, manufacturers are beginning to make ambitious commitments to keep new plastics out of the environment.
Wild Bumblebee Queens Lured and Killed in Commercial Hives
In the course of experiments to test how well commercial bumblebees pollinate early spring crops, researchers made a surprising discovery: dead wild bumblebee queens in the hives, an average of 10 per nest box.
How to make hydrogels more injectable
Gel-like materials that can be injected into the body hold great potential to heal injured tissues or manufacture entirely new tissues. Many researchers are working to develop these hydrogels for biomedical uses, but so far very few have made it into the clinic.
