Wildfires among ponderosa pines and Douglas firs of the U.S. West have long been part of nature's cycle of renewal, as much as the changing of the seasons. Scientists worry the hottest blazes could end up obliterating swathes of some forests forever. "When you get these large areas burned there are no surviving trees to reseed these areas," said Jon Keeley, a research scientist with the U.S....

Ice in the Arctic Ocean melted to its second lowest level on record this summer, triggered by global warming along with natural forces, U.S. scientists reported Monday. The extent of ice-covered ocean at the North Pole and extending further south to Alaska, Canada, Greenland and Russia reached its summertime low of 1.4 million square miles (3.7 million square kilometers) last week before starting...

Elon Musk wants to settle humans on Mars with his rocket company SpaceX. Amazon's founder, Jeff Bezos, wants a trillion people living in space. But the chief executive of one private space company is approaching space exploration differently, and now aims to play a part in the search for life on Venus.Last week, scientists announced the astonishing discovery of phosphine in the atmosphere of...

COVID-19 is a reminder that "we are all in it together" and the world needs a global response to the climate change crisis, David Attenborough said, as he launched a film about lessons learned during his seven decades as a television naturalist. The film "David Attenborough: A Life On Our Planet" sets out his "witness statement" on the destruction of the environment and ideas on how humans can...

A shark's skin is made up of thousands of armor-like scales, known as denticles. Now, humans are copying that pattern to fight the spread of...

Warming in the Arctic shrank the ice covering the polar ocean this year to its second-lowest extent in four decades, scientists announced Monday, yet another sign of how climate change is rapidly transforming the region. Satellites recorded this year's sea ice minimum at 3.74 million square kilometers on Sept. 15, only the second time the ice has been measured below 4 million square kilometers in...

Botswana wildlife officials said on Monday that toxins produced by microscopic organisms called cyanobacteria had caused the deaths of 330 elephants this year. Since they were first reported around early May, the elephant deaths had baffled and alarmed conservationists, who feared they could escalate. Below are some facts about...

Egyptian archaeologists have unearthed more than two dozen ancient coffins in a vast necropolis south of Cairo, an official said Monday. The sarcophagi have remained unopened since they were buried more than 2,500 years ago near the famed Step Pyramid of Djoser in Saqqara, said Neveine el-Arif, a spokeswomen for the Ministry of Tourism and Antiquities. Footage shared by the ministry showed...

A new study that analyzed the coronavirus outbreak in Brazil has found a link between the spread of the virus and past outbreaks of dengue fever that suggests exposure to the mosquito-transmitted illness may provide some level of immunity against COVID-19. The not yet published study led by Miguel Nicolelis, a professor at Duke University, and shared exclusively with Reuters, compared the...

Publicly traded U.S. companies have been slow to add minority directors over the past five years even as women grabbed a greater share of board seats during that period, a comprehensive study to be released on Monday shows. Across the Russell 3000, a broad index of U.S. companies, 29% now have two or more ethnically diverse directors, 7 percentage points more than in 2016, according to the new...

Toxins in water produced by cyanobacteria killed more than 300 elephants in Botswana this year, officials said on Monday, announcing the result of an investigation into the deaths which had baffled and alarmed conservationists. Cyanobacteria are microscopic organisms common in water and sometimes found in soil. Not all produce toxins but scientists say toxic ones are occurring more frequently as...

In the forests and on remote offshore islands of Taiwan, a group of conservationists are racing to collect as many rare plant species as they can before they are lost to climate change and human encroachment. Overseen by the Dr. Cecilia Koo Botanic Conservation Centre, the plant hunters are scouring sub-tropical Taiwan for as many rare plant samples as they can find, from the rugged eastern coast...
