Evolving warm-bloodedness and an upright posture after a massive extinction event allowed the ancestors of mammals and birds to survive — and thrive, said paleontologist Mike...
It's possible to build a roller coaster as high as the tallest building in the world, the Burj Khalifa. But it could seriously injure or kill...
A new method for verifying a widely held but unproven theoretical explanation of the formation of stars and planets has been proposed by researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL). The method grows from simulation of the Princeton Magnetorotational Instability (MRI) Experiment, a unique laboratory device that aims to demonstrate the MRI process...
Large wildfires may be linked to increases in COVID-19 cases and deaths in the San Francisco area, according to a paper in the European Review for Medical and Pharmacological Sciences. Researchers found that between March and September, increases in smoke particles, other wildfire pollutants and carbon monoxide levels corresponded to increases in daily COVID-19 diagnoses and total COVID-19...
The presence of insecticides in streams is increasingly a global concern, yet information on safe concentrations for aquatic ecosystems is sometimes sparse. In a new study led by Colorado State University's Janet Miller and researchers at the United States Geological Survey, the team found a common insecticide, fipronil, and related compounds were more toxic to stream communities than previous...
As the world enters a next wave of the ongoing COVID-19 pandemic, we are aware now more than ever of the importance of a healthy immune system to protect ourselves from disease. This is not only true for humans but corals too, which are in an ongoing battle to ward off deadly diseases spreading on a reef.
In 2000, children's author Michael Kusugak named a group of Saturn's many moons. Twenty years later, he's looking to rename the street near his...
Scientists have discovered the first nest of so-called murder hornets in the United States and plan to wipe it out Saturday to protect native honeybees, officials in Washington state said.
Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team.
A team led by scientists at Scripps Research has developed a theoretical approach that could ease the process of making highly complex, compact molecules.
If you flew from the sea towards the land in the north slope of Alaska, you would cross from the water, over a narrow beach, and then to the tundra. From the air, that tundra would look like a landscape of room-sized polygonal shapes. Those shapes are the surface manifestations of the ice in the frozen ground below, a solidified earth known as permafrost.
Facing increased pressure to protect woodland caribou herds, the federal and Alberta governments have signed a conservation agreement aimed at restoring dwindling herds in the...
Scientists from Scripps Research and Los Alamos National Laboratory have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system.
Researchers at Rice University and Baylor College of Medicine have developed a new method to isolate specific cells, and in the process found a more robust fluorescent protein.
The news: The NYU Ad Observatory released new data this week about the inputs the Trump and Biden campaigns are using to target audiences for ads on Facebook. It’s a jumble of broad and specific characteristics ranging from the extremely wide (“any users between the ages of 18-65”) to particular traits (people with an “interest in Lin-Manuel Miranda”). Campaigns use these...

A 14,000-year paleoecological reconstruction of the sub-Antarctic islands has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Islands ecosystems through the deposit of high concentrations of guano that helped nourish tussac, produce peat and increase the incidence of fire.

Research has found permafrost to be mostly absent throughout the shallow seafloor along a coastal field site in northeastern Alaska. That means carbon can be released from coastline sources much more easily than previously thought.
All biological processes are in some way pH-dependent. Human bodies and those of other organisms need to maintain specific and constant pH regulation in order to function. Changes in pH can have serious biological consequences—or serious benefits, as researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS) found.
The Falkland Islands are a South Atlantic refuge for some of the world's most important seabird species, including five species of penguins, Great Shearwaters, and White-chinned Petrels. In recent years, their breeding grounds in the coastal tussac (Poa flabellata) grasslands have come under increasing pressure from sheep grazing and erosion. And unlike other regions of the globe, there has been...
Scientists have discovered the first nest of so-called murder hornets in the United States and plan to wipe it out Saturday to protect native honeybees, officials in Washington state said. After weeks of searching, the agency said it found the nest of Asian giant hornets in Blaine, a city north of Seattle near the Canadian border. The world’s largest hornet at 2 inches (5 centimeters) long,...
Stress is present everywhere, even bacteria and plant cells have to cope with it. They express various specific stress proteins, but how exactly this line of defense works is often not clear. A group of scientists has now discovered a protective mechanism in cyanobacteria as well as in chloroplasts of plant cells.
Bob McDonald's blog: Paint that can actually cool buildings, and tinted windows that generate solar power could be important innovations in reducing energy used by...
There is much debate surrounding the age of the Clovis—a prehistoric culture named for stone tools found near Clovis, New Mexico in the early 1930s—who once occupied North America during the end of the last Ice Age. New testing of bones and artifacts show that Clovis tools were made only during a brief, 300-year period from 13,050 to 12,750 years ago.
