Offshore wind farms could power much of coastal China

If China is to meet and exceed its Paris Climate Agreement goal by 2030, it's going to need to find a way to increase its wind capacity. Researchers found that offshore wind could be a big part of the solution.

Genetics of how corn can adapt faster to new climates

Researchers have decoded the genetic map for how maize from tropical environments can be adapted to the temperate US summer growing season. They believe that if they can expand the genetic base by using exotic varieties, they might be able to counter stresses such as emerging diseases and drought associated with growing corn in a changing climate.

Fossilized wing gives clues about Labrador's biodiversity during the Cretaceous

A fossilized insect wing discovered in an abandoned mine in Labrador has led palaeontologists to identify a new hairy cicada species that lived around 100 million years ago.

Why do whales migrate? They return to the tropics to shed their skin

Whales undertake some of the longest migrations on earth, often swimming many thousands of miles, over many months, to breed in the tropics. The question is why? Scientists propose that whales that forage in polar waters migrate to low latitudes to maintain healthy skin.

Frozen bird turns out to be 46,000-year-old horned lark

Scientists have recovered DNA from a well-preserved horned lark found in Siberian permafrost. The results can contribute to explaining the evolution of sub species, as well as how the mammoth steppe transformed into tundra, forest and steppe biomes at the end of the last Ice Age.

Himalayan wolf discovered to be a unique wolf adapted to harsh high altitude life

Researchers have discovered that the Himalayan wolf is a unique wolf characteristically adapted to the harsh life in the Asian high altitudes where low oxygen levels challenge all life forms.

New studies explore how knowledge drives action in climate change decision-making

In several new studies, researchers explore the importance of learning and knowledge in environmental decision-making and the different ways in which scientific knowledge can become more relevant and useful for societies.

A better pregnancy test for whales

To determine whale pregnancy, researchers have relied on visual cues or hormone tests of blubber collected via darts, but the results were often inconclusive. Research points to a weakness of previous testing and evaluation methods and provides a new hormone testing regime that offers better results.

Water reuse could be key for future of hydraulic fracturing

Enough water will come from the ground as a byproduct of oil production from unconventional reservoirs during the coming decades to theoretically counter the need to use fresh water for hydraulic fracturing operations in many of the nation's large oil-producing areas. While other industries might want to recycle some of that water for their own needs, water quality issues and the potential costs involved may be prohibitive.

DNA from ancient packrat nests helps unpack Earth's past

New work shows how using next-generation DNA sequencing on ancient packrat middens -- nests made out of plant material, fragments of insects, bones, fecal matter, and urine -- could provide ecological snapshots of Earth's past. The study may pave the way for scientists to better understand how plant communities -- and possibly animals, bacteria, and fungi as well -- will respond to human-caused climate change.

How transient invaders can transform an ecosystem

Study finds microbes can alter an environment dramatically before dying out.

Huge stores of Arctic sea ice likely contributed to past climate cooling

Climate scientists propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8,000 to 13,000 years ago.

Earth formed much faster than previously thought, new study shows

By measuring iron isotopes, researchers have shown that our planet originally formed much faster than previously thought. This finding provides new insights on both planetary formation and the likelihood of water and life elsewhere in the universe.

The climate and increased extreme weather affect our energy systems

Climate change, with more and more storms and heat waves, also has consequences for our energy supply. An international research team has now developed a new method for calculating how extreme weather affects energy systems.

New strategies for helping children process negative emotions

A recent study of indigenous people in southern Chile challenges Western assumptions about children's emotional capabilities and highlights the value of spending time outdoors to help children regulate their emotions.

Risk of coronavirus importation in Africa

Egypt, Algeria and Republic of South Africa are the African countries most at risk for coronavirus COVID-19 importation in the continent, due to high air traffic with the contaminated Chinese provinces. But these countries are also among the best equipped on the continent to quickly detect and deal with new cases. In other African countries, the risk of importation is lower, but health organization deficiencies raise concerns about rapid spread.

Earthquakes disrupt sperm whales' ability to find food

Scientists studying sperm whales have discovered earthquakes affect their ability to find food for at least a year. The research is among the first to examine the impact of a large earthquake on a population of marine mammals, and offers new insight into how top predators such as sperm whales react and adapt to a large-scale natural disturbance.

'Wood' you like to recycle concrete?

Scientists studied a method for recycling unused concrete with wood fibers. They found the conditions that produce new building materials with bending strength even greater than the original concrete. This work may help reduce the CO2 emissions associated with manufacturing new concrete.

Illuminating interactions between decision-making and the environment

Employing a game theory model, researchers demonstrate how strategic decisions influence the environment in which those decisions are made, alterations which in turn influence strategy. Their analysis, which identifies how incentives can tip a strategy from one extreme to another, applies to fields as diverse as fisheries dynamics to climate change policy.
