Evolution after Chicxulub asteroid impact: Rapid response of life to end-cretaceous mass

The impact event that formed the Chicxulub crater (Yucatán Peninsula, México) caused the extinction of 75% of species on Earth 66 million years ago, including non-avian dinosaurs. One place that did not experience much extinction was the deep, as organisms living in the abyss made it through the mass extinction event with just some changes to community structure.

Road verges could be havens for pollinators

Better-managed road verges can help boost pollinating insects, new research shows.

Sea surface temperature has a big impact on coral outplant survival

A new study has shown that coral outplant survival is likely to drop below 50% if sea surface temperatures exceed 30.5 degrees Celsius and that survival rates can also be predicted by considering temperature conditions in the year prior to outplanting.

Ways to keep buildings cool with improved super white paints

Materials scientists have demonstrated ways to make super white paint that reflects as much as 98% of incoming heat from the sun. The advance shows practical pathways for designing paints that, if used on rooftops and other parts of a building, could significantly reduce cooling costs, beyond what standard white 'cool-roof' paints can achieve.

A 'regime shift' is happening in the Arctic Ocean

Scientists find the growth of phytoplankton in the Arctic Ocean has increased 57 percent over just two decades, enhancing its ability to soak up carbon dioxide. While once linked to melting sea ice, the increase is now propelled by rising concentrations of tiny algae.

Socio-economic, environmental impacts of COVID-19 quantified

How is COVID-19 impacting people and the planet and what are the implications for a post-pandemic world? A new study quantifies the socio-economic losses and environmental gains.

Technique fishes valuable nutrients out of shrimp processing water

The seafood industry requires large amounts of water for food processing. Before used water is discharged, some organic matter, including protein, is typically removed. This sludge is usually landfilled or converted into biogas, which results in the valuable nutrients it contains being lost from the food chain. Now researchers report a method to recover these nutrients from shrimp processing water so they can be incorporated in food or feed.

Making a list of all creatures, great and small

A new article outlines a roadmap for creating, for the first time, an agreed list of all the world's species, from mammals and birds to plants, fungi and microbes.

1.5 billion people will depend on water from mountains

Global water consumption has increased almost fourfold in the past 100 years, and many regions can only meet their water demand thanks to essential contributions from mountain regions. In 30 years, almost a quarter of the world's lowland population will strongly depend on runoff from the mountains. Only sustainable development can ensure the important function of mountain areas as Earth's ''water towers''.

Tree rings show unprecedented rise in extreme weather in South America

A new South American Drought Atlas reveals that unprecedented widespread, intense droughts and unusually wet periods have been on the rise since the mid-20th century.

Microplastic pollution harms lobster larvae, study finds

Microplastic fiber pollution in the ocean impacts larval lobsters at each stage of their development, according to new research. A study reports that the fibers affect the animals' feeding and respiration, and they could even prevent some larvae from reaching adulthood.

Plant study challenges tropics' reputation as site of modern evolutionary innovation

In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as the tropics.

Heatwave trends accelerate worldwide

The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950's. The research has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons. As expected, that number is also on the rise.

Coconut confusion reveals consumer conundrum

Coconut oil production may be more damaging to the environment than palm oil, researchers say.

Nitrogen pollution policies around the world lag behind scientific knowledge

National and regional policies aimed at addressing pollution fueled by nitrogen lag behind scientific knowledge of the problem.
