Hundreds of fossils uncovered in southern China's province of Yunnan reveal that at least some of the life-forms scientists had thought arose in the Cambrian period were alive and thriving millions of years earlier, in an era known as the Ediacaran period.

Four protrusions appear to be arranged in pairs, each consisting of two connected branches surrounding a central depression. We really don't understand what any of these features represent anatomically.

Wildfires have become an ever bigger problem in Canada. The 2018 wildfires were the biggest in British Columbia's history, but this record was broken in 2021, and then again in 2023, when fires consumed an area three times the size of the Canadian province of Nova Scotia and the smoke travelled as far as New York City.

At a young age, I learned quickly how oil wealth and power could burn the land while people struggled. I saw heat rise off the streets, the Nile strained, and the air thickened with injustice. In my teenage years, through Aotearoa, being on the edge of the Pacific, I felt the ocean breathing heavy, swallowing the shores of islands that have done the least to cause this harm.

We found our route but advanced only a few hundred yards before encountering an impassable logjam. The dense forests on either side meant that we couldn't go around it, only through.

The repeal of the 2009 Endangerment Finding removed the legal basis for all federal greenhouse gas regulation for cars, power plants, and oil fields at once.

The only interest he has in our parks is the money he can make from them. Case in point is how Socha, as an executive for the hospitality company Delaware North, sued the NPS for $51 million for the naming rights to Yosemite National Park, Ahwahnee, Wawona, etc., claiming they were the company's intellectual property. Twenty-two years as concessionaire entitles them to own and profit from the names? How absurd and disrespectful.

Less than a year ago, United States company Colossal Biosciences announced it had "resurrected" the dire wolf, a megafauna-hunting wolf species that had been extinct for 10,000 years. Within two days of Colossal's announcement, the Interior Secretary of the US, Doug Burgum, used the idea of resurrection to justify weakening environmental protection laws: "pick your favourite species and call up Colossal". His reasoning appeared to confirm critics' fears about de-extinction technology. If we can bring any species back, why protect them to begin with?

But to environmental advocates, the announcement sounded less like relief and more like a bill for working people, one that would result in higher fuel costs, increased pollution, and a slower path to clean energy. Critics warn that the decision represents a blow to the energy transition and a significant setback in the fight against climate change overall.

Recent examination of some ancient rocks from the west coast of Scotland have now overturned that thinking, suggesting there were periods during snowball Earth when the climate woke up. Close-up views of thin, repeating rock layers known as varves, each thought to represent a single year of sedimentation during the snowball Earth period.

These sagebrush-covered foothills of primarily Bureau of Land Management land have a higher concentration of sage grouse than anywhere else on the planet, likely in part because the birds have room to move. More than a thousand elk winter there, too, sustained by the high-elevation landscape's cured grasses, dried wildflowers and shrubs. So do pronghorn and mule deer, wintering or using the area as a stopover on their journeys, which include the longest documented mule deer and pronghorn migrations in the Lower 48.

OHSU's National Primate Research Center may be no more, much to the delight of animal welfare advocates, who have long been pushing the university to shut the doors on its monkey research facility. Yesterday, OHSU's board voted unanimously to look into transitioning the center-which, with about 5,000 primates, is one of the largest research centers of its kind in the US-into a monkey sanctuary.

My father was a petroleum geologist. A lot of my childhood, he was gone, away on oil rigs in the Powder River Basin and remote parts of Wyoming, living in man camps long before cellphones. We had to wait days to talk to him. When he went into the nearest town to shower, he'd find a payphone and call us. I was always breathless with news.

At first glance, it looked like Wooller and his colleagues might have found evidence that mammoths lived in central Alaska just 2,000 years ago. But ancient DNA revealed that two "mammoth" bones actually belonged to a North Pacific right whale and a minke whale-which raised a whole new set of questions. The team's hunt for Alaska's last mammoth had turned into an epic case of mistaken identity, starring two whale species and a mid-century fossil hunter.

Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures. It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years.

From the beginning, we knew these bones were exceptional because of their minute size. It is equally impressive how the study of this animal overturns global ideas on ornithopod dinosaur evolution,

Last year, the nonprofit Climate Central launched an online database to track the most costly weather- and climate-related disasters across the country. The effort was led by the same lead scientist who tracked those costs for the National Oceanic and Atmospheric Administration-until the Trump administration axed the project in May. In 2025, the US experienced 23 such disasters with costs totaling at least $1 billion, for a total of $115 billion, Climate Central concluded.

The world spends 30 times more money destroying nature than protecting it. That's according to a new report from the United Nations Environment Programme (UNEP) that exposes a massive gulf between so-called "harmful investments" and financing that promotes nature preservation. The global environment agency's latest "State of Finance for Nature" (SNF) report is calling to phase out the US$7.3 trillion (6.2 trillion) in global investments that damage nature including into high-emissions energy infrastructure and manufacturing, for example.

"The numbers are really, really bad," Swain says. "If this were November, they might be less meaningful. We're not in November-we're heading toward mid-February. The normal numbers are pretty high. To be at half of them means that, in absolute terms, the deficit is large."
