The first modern barcode was scanned 50 years ago this summer – on a 10-pack of chewing gum in a grocery store in Troy, Ohio. Fifty is ancient for most technologies, but barcodes are still going strong. More than 10 billion barcodes are scanned every day around the world. And newer types of barcode symbols,...

AI Found to Boost Individual Creativity – at the Expense of Less Varied Content
Stories written with AI assistance have been deemed to be more creative, better written and more enjoyable. A new study published in the journal Science Advances finds that AI enhances creativity by boosting the novelty of story ideas as well as the ‘usefulness’ of stories – their ability to engage the target audience and potential for publication....
‘A History of Contact’: Princeton Geneticists Are Rewriting the Narrative of Neanderthals and Other Ancient Humans
Ever since the first Neanderthal bones were discovered in 1856, people have wondered about these ancient hominins. How are they different from us? How much are they like us? Did our ancestors get along with them? Fight them? Love them? The recent discovery of a group called Denisovans, a Neanderthal-like group who populated Asia and...
The Evidence Is Mounting: Humans Were Responsible for the Extinction of Large Mammals
The debate has raged for decades: Was it humans or climate change that led to the extinction of many species of large mammals, birds, and reptiles that have disappeared from Earth over the past 50,000 years? By “large,” we mean animals that weighed at least 45 kilograms – known as megafauna. At least 161 species...
Researchers From UNH and Northeastern Dig into History to Uncover a “King”
Archaeologists at the University of New Hampshire along with a historian at Northeastern University believe they have unearthed the long-lost homestead of King Pompey, an enslaved African who won his freedom and later became one of the first Black property owners in colonial New England. “We are thrilled,” said Meghan Howey, professor of anthropology and...
Bringing Back an Ancient Bird
Using ancient DNA extracted from the toe bone of a museum specimen, Harvard biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. Published in Science Advances, the work is the first complete genetic map of the turkey-sized bird whose distant living cousins...
Model Disgorgement: the Key to Fixing AI Bias and Copyright Infringement?
– Ian Scheffler By now, the challenges posed by generative AI are no secret. Models like OpenAI’s ChatGPT, Anthropic’s Claude and Meta’s Llama have been known to “hallucinate,” inventing potentially misleading responses, as well as divulge sensitive information, like copyrighted materials. One potential solution to some of these issues is “model disgorgement,” a set of techniques that force models to...
Physics Confirms That the Enemy of Your Enemy Is, Indeed, Your Friend
Most people have heard the famous phrase “the enemy of my enemy is my friend.” Now, Northwestern University researchers have used statistical physics to confirm the theory that underlies this famous axiom. The study published on May 3 in the journal Science Advances. In the 1940s, Austrian psychologist Fritz Heider introduced social balance theory, which explains...
The Mars Sample Return Mission Has a Shaky Future, and NASA Is Calling on Private Companies for Backup
A critical NASA mission in the search for life beyond Earth, Mars Sample Return, is in trouble. Its budget has ballooned from US$5 billion to over $11 billion, and the sample return date may slip from the end of this decade to 2040. The mission would be the first to try to return rock samples...
Can Bismuth Prevent Oil Leaks – (And Save Norwegians Billions)?
Over the next 25 years, as the world shifts away from fossil fuels, the oil and gas wells that have sustained the fossil fuel age will have to be plugged. No big deal, you might think, drilling those wells was the hard part. Plugging them should be no problem. But think again. The Norwegian Continental...
