Thousands of Clovis point tools have been found in North America, but exactly how they were used has been the subject of debate.
"If molecules continually exchange between droplets or between cells, then all the cells after a short while will look alike," researcher Aman Agrawal said.
New research by the University of Liverpool has revealed how an underwater avalanche grew more than 100 times in size, causing a huge trail of destruction as it traveled 2,000km across the Atlantic Ocean seafloor off the North West coast of Africa.
One of the major unanswered questions about the origin of life is how droplets of RNA floating around the primordial soup turned into the membrane-protected packets of life we call cells.
According to a new study, as of April 2021, US Congress members whose ancestors enslaved 16 or more people had a net worth that was five times higher than that of legislators whose ancestors did not have slaves. Neil Sehgal of the University of Pennsylvania, US, and Ashwini Sehgal of Case Western Reserve University, US present these findings in the open-access journal PLOS ONE on August 21, 2024.
As the human population grows, more than half of Earth's land will experience an increasing overlap between humans and animals by 2070, according to a University of Michigan study.
Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron—an object traveling so fast it could circle the Earth many times in a matter of a second. Researchers at the University of Arizona have developed the world's fastest electron microscope that can do just that.
In recent years, the news about Earth's climate—from raging wildfires and stronger hurricanes, to devastating floods and searing heat waves—has provided little good news.
How did early humans use sharpened rocks to bring down megafauna 13,000 years ago? Did they throw spears tipped with carefully crafted, razor-sharp rocks called Clovis points? Did they surround and jab mammoths and mastodons? Or did they scavenge wounded animals, using Clovis points as a versatile tool to harvest meat and bones for food and supplies?
Researchers at Stanford and Colorado State University have developed a rapid, low-cost approach for studying how individual extreme weather events have been affected by global warming. Their method, detailed on Aug. 21 in Science Advances, uses machine learning to determine how much global warming has contributed to heat waves in the U.S. and elsewhere in recent years.
Even the most capable robots aren’t great at sensing human touch; you typically need a computer science degree or at least a tablet to interact with them effectively. That may change, thanks to robots that can now sense and interpret touch without being covered in high-tech artificial skin. It’s a significant step toward robots that…
For the first time, climate scientists have explicitly said it will be impossible to limit peak warming to 1.5°C. Now our focus should be on taking action, not meaningless platitudes and slogans
Scientists have created the world's fastest microscope, which they hope will answer fundamental questions about how electrons behave.
Houston’s warm, wet spring, driven in part by climate change, was a boon for mosquitoes and West Nile virus
U.S. Senators and Representatives whose family had a history of enslaving others have greater present-day wealth
The most striking thing about the Democratic nominee’s economic platform is its timidity. She could go much further to lift up the working class.
A recent study has proposed four possible routes to connect the existing MoPac East trail from the Elmwood area to the Lied Bridge over the Platte River outside Louisville.
A viral video reminds us that God works through disciples, not edgelords.

ThredUp is testing a peer-to-peer resale marketplace, shifting from its traditional managed RaaS model, aiming to compete with platforms like Depop.
Long owned by late home hardware and bath accessories moguls Sherle and Rose Wagner, the modern Palm Beach residence is now on the market for the first time in nearly 40 years.
Deer, elk, giraffes, and other ungulates may have all gotten their headgear from a common ancestor that lived 15 million years to 20 million years ago.
The European Commission announced this AM that, in its ongoing findings of an anti-subsidy investigation into Chinese imports of battery electric vehicles, all Tesla vehicles imported from China will be subject to a 9% tariff. Proposed tariffs on other EV companies were revised slightly ahead of what could become EU trade policy later this year. Of all the proposed duties on Chinese EVs imported to the EU, Tesla appears to be the big winner and will pay the lowest rate of 9%. Reuters noted the EU "set a new reduced rate of 9% for Tesla...
