Little Punch, a seven-month-old Japanese macaque living in the Ichikawa City Zoo in Japan, has captured hearts on the internet. Abandoned by his mother in the first few days of his life and raised by the keepers at the zoo, he has had some trouble integrating into the group of
Do the bones of all Nile crocodiles have the same number of growth marks as their age? And can such growth rings be counted to accurately gauge the age of these reptiles? Is this also an accurate method to use when trying to "age" dinosaurs and other extinct and extant
Students using AI to cheat on homework or tests is a source of much discussion. But some scholars argue the greater risk of students using AI is that they will simply not learn.
Between 1347 and 1353, Europe was gripped by the most catastrophic pandemic in its history: the Black Death. Killing many millions, the plague wiped out between one-third and a half of Europe's population.
Researchers at the University of Vienna have uncovered a surprising phenomenon: polymer chains with segments that simply fluctuate at different intensities can spontaneously develop directional, persistent motion when densely packed—even though nothing in the system points them
As a space scientist, every time I go outside with my family, I tell my children to look up at the sky. The front door of our home looks southeast, and on winter nights the constellation Orion hangs majestically just above the horizon as soon as it grows dark enough to see stars.
The past three years have been the world's hottest on record by far, with 2025 almost tied with 2023 for second place. With that energy came extreme weather, from flash flooding to powerful hurricanes and severe droughts. Yet, by most indicators, the planet should have been
Polypropylene and polyethylene are two durable and affordable plastics commonly used as packaging materials, snack wrappers, microwave containers, and other, usually flexible, plastic films. Their flexibility, however, makes them resilient to recycling processes, and these
From brightly colored textile dyes to persistent pesticides and antibiotics, many modern pollutants dissolved in water—such as Bisphenol A—resist traditional treatment methods. A promising approach uses electricity to power chemical reactions in water over an electrode surface.
When analyst attention is absorbed by CEO turnover, other companies in their portfolio pay the price, new Cornell research finds. The study, "Analyst Rational Inattention: Evidence from CEO Turnover Events," published in the Accounting Review, finds that high-impact turnover
How do biological cells join forces to form a structure? In her Ph.D. research, Daphne Nesenberend uses mathematics to show how forces and cooperation between cells create structure—and how simulations and experiments can reinforce each other.
Genes that play a key role in the formation of an infectious organ used by parasitic plants have been identified by plant scientists at RIKEN. This discovery fills a gap in our understanding of how parasitic plants infect their hosts. The research is published in the journal
During the hottest summer days in New Haven's Dwight neighborhood, the kids at Kensington Playground improvise a way to stay cool—wedging T-shirts along the splash pad drain to form a makeshift pool. As the water rises, they lie on their stomachs in a circle around the drain,
Due to climate change, agriculture is facing an unprecedented transformation. While Germany was hardly affected by massive crop failures for decades, the picture has changed drastically since 2015. Since then, heat waves and dry spells have been responsible for yield losses in
Biology textbooks explain that cells follow a universal rule when processing gene transcripts to make proteins. Non-coding snippets of RNA are bracketed by a guanine-thymine (GT) nucleotide sequence on one end and an adenine-guanine (AG) sequence on the other—unmistakable
A new study finds that heart attack deaths in U.S. hospitals are rising in people aged 54 and below, signaling a shift in cardiovascular issues in younger ages
All complex biological systems—like the DNA, RNA and proteins constantly being copied and built within our cells—are prone to errors. That means as life evolved to be more elaborate, it also had to evolve error-correcting strategies.
A new catalog of gravitational waves more than doubles the known number of these spacetime ripples
When Vasilis Rodovitis rips open his brown paper bag in a sunny persimmon orchard just outside Naousa, in Greece, I half expect groceries to spill out. Instead, a barely there gray cloud emerges. For half a week, the bag was home to some 4,000 Mediterranean fruit flies
To misquote a famous song, "Diamonds are industry's best friend." Cubic diamond is the hardest mineral on Earth and is used in everything from precision cutting tools to high-performance semiconductors as well as expensive jewelry. But there is a rare and potentially tougher
Anyone familiar with the search for alien life will have heard of the "Goldilocks Zone" around a star. This is defined as the orbital band where the temperature is just right for liquid water to pool on a rocky planet's surface—a good approximation for what we thought of as the
Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster known as NGC 2158. Results of the study, published Feb. 25 on the arXiv pre-print server, provide essential insights into the population of binary stars in
