Museums house thousands of animal specimens that are ancient, extinct, newly discovered and have yet to be studied. New York's American Museum of Natural History has 33 million specimens inside, while the Smithsonian's National Museum of Natural History in Washington D.C. has a whopping 145 million holdings.While most animals collected by these institutions have been obtained legally, euthanized painlessly and researched with respect, some researchers often wonder whether there could be a better ...read more
We like to think of ourselves as special. We’re Homo sapiens, after all. But a new study of Ice Age Europe has found that our supposedly unique bone tools, a sign of higher intelligence, weren’t so unique after all. Neanderthals fashioned and used hundreds of the same tools while butchering animals and preparing hides, according to a new paper.Evidence for this has arisen, in recent years, from two Neanderthal sites of some note – starting with the Chagyrskaya Cave in the Altai Mountains i ...read more
Although dirt doesn’t seem to be particularly interesting on the surface — we often picture a lifeless, unremarkable substance beneath our feet — it’s actually a dynamic ecosystem teeming with organisms. And these organisms hold the power to make or break all of life on Earth.One such unsung hero is the humble earthworm and, most importantly, its toilet habits. If you plop your spade into a patch of healthy soil, chances are that most of this is stuff that's come out the back end of an e ...read more
Humans lived in South America many thousands of years earlier than previously believed, during the height of the Last Ice Age. A new archaeological study discovered this by analyzing a trio of necklaces made from ground sloth bones. The project wades into an ongoing debate over when and how Homo sapiens, who evolved in Africa and first spread to Europe and Asia, made it to the relatively remote Americas.How Did Humans Settle the Americas?In the conventional view of American settlement, human bei ...read more
A female American crocodile has spent her entire life in captivity in a reptile park in Costa Rica and just laid several fertile eggs — without mating first.This recent event means that researchers are now adding crocodilians to a growing list of birds, reptiles, amphibians and fish that can generate offspring without the help of a male mate.“It’s likely that this has happened for thousands and thousands of years and [has] just been missed,” says Warren Booth, an evolutionary biologist a ...read more
The Earth hasn’t always had ozone — or even oxygen — in its atmosphere. Our planet spent more than 2.4 billion years with an oxygen concentration of less than 1 part per million, in fact. While the element is plentiful throughout the universe, what little Earth was born with quickly evaporated away into space.It wasn’t until the arrival of plants and photosynthesis, which consumes abundant carbon dioxide from the atmosphere and leaves oxygen as a byproduct, that the concentration of ox ...read more
“Doubt has killed more dreams than failure ever will,” is a popular Suzy Kassem quote, especially for those who are too afraid of failing at something that they don’t even bother to try. Think of all the songs and books that were never written or the athletes and artists that never made it because they were too afraid of failing. Or, imagine the pressure professional athletes or musicians feel to perform well enough that the audience isn’t disappointed in them. This doubt or fear is wh ...read more
You probably know them, even if you don’t love them. They pop up on social media and in text messages — how else would you share your Wordle score without giving away the solution? — and have even infiltrated advertisements and work emails. In 2015, the Oxford Dictionary chose one as its “word” of the year.We’re talking, of course, about emojis. The colorful pictographs are superb substitutes for those things that are sometimes lost in text-based communication: emotions, body langu ...read more
A new paper proposes that the universe's first stars were about as different from twinkling, sunlike stars as you can get. These "dark stars," it argues, were fueled by huge globs of annihilating dark matter and seeded the galaxies we see today.Strange as they are, such stellar bodies explain one of the newer mysteries in astronomy.In December 2022, the James Webb Space Telescope identified three ancient galaxies as part of its JWST Advanced Deep Extragalactic Survey (JADES). These distant, deep ...read more
This article was originally published on Nexus Media News.Duke Riley started out making maritime crafts, like sailor’s valentines and scrimshaws, entirely out of shells, bones and other natural materials that washed ashore on the beaches of Cape Cod, Massachusetts and greater New York. Then, on a walk in 2017, he picked up what he thought was a piece of bone. Upon closer inspection, he realized it was a plastic brush used for scrubbing boats. The moment marked a turning point in his practi ...read more
