Humans love to take liberties when we talk about our heights. But Afruca tangeri fiddler crabs don’t have that luxury. Looking and listening in on the members of this species as they tried to attract mates, a team of researchers found that the males’ mating songs are shaped by their size, and are thus accurate signals of their fitness as mates, according to a press release, at least from the perspective of female fiddler crabs.Publishing their findings in a study in the Journal of Experiment ...read more

One of the most important parts of living a healthy lifestyle is getting a good night’s sleep. Quality sleep can prevent illness, reduce stress, and enhance cognitive function, just to name a few. A research team working with the Baycrest Corporate Centre for Geriatric Care has now added a new benefit to the list: unlocking the brain’s ability to sort memories. According to a study published in Nature Human Behaviour, sustained deep sleep not only safeguards against memory decline but also ...read more

Black holes — the supermassive gravitation forces at the center of most galaxies — actually spend much of their time dormant, or essentially asleep. Astronomers have now spotted one not only waking up but appearing to hit the celestial equivalent of a snooze button every few days. The black hole at the center of a galaxy named SDSS1335+0728, about 300 million light-years away, first showed signs of stirring when, in 2019, the galaxy started shining brightly. But since 2024, that black hole t ...read more

Every April, as winter’s grip finally loosens and the nights grow a little warmer, Earth drifts through a centuries-old cloud of cosmic dust. That’s when the Lyrid meteor shower — one of the oldest known and most reliable meteor showers of the year — lights up the night.The Lyrids will peak overnight from April 21, 2025 into April 22, 2025 this year. On the days near that peak, patient skywatchers may be treated to a modest but mesmerizing display of shooting stars streaking across the s ...read more

Back in 1950, Alan Turing proposed an elegantly simple yet profoundly challenging way to determine whether machines could be said to "think." Known as the Turing Test, this measure of machine intelligence sets humans and machines in conversational competition, challenging human judges to distinguish between artificial and genuine intelligence through text-based interactions. Despite numerous attempts, no artificial system had ever convincingly passed this test. Until now.Cameron Jones and Benjam ...read more

It might be time to grant the monkeypox virus a new name. Although the virus (mpox for short) was first detected in lab monkeys in 1958, the original host or reservoir has remained unknown. Identifying the reservoir is crucial, because it gives epidemiologists targets to help control outbreaks. For the monkeypox virus, experts need to shield people from the fire-footed rope squirrel (Funisciurus pyrropus), which lives in the forests of West and Central Africa.Mystery Monkeypox SourceA team of sc ...read more

The first full moon of spring, called the “Pink Moon,” will soon ascend in the night sky. Curious onlookers can expect to catch a glimpse of the full moon's peak at 8:22 p.m. Eastern Daylight Time (EDT) on April 12, 2025, yet the lack of a rosy hue may leave many people perplexed. The Pink Moon is significant for many reasons, but its color is not one of them; despite the vibrant name, the Pink Moon is not actually pink. Find out the true reason for this full moon’s colorful moniker, as w ...read more

Modern rhinos aren’t Nebraskan animals. And they aren’t North American animals, either. But millions of years ago, rhinos were. In the Middle Miocene, Teleoceras major rhinos lived across Nebraska and across much of North America, too.Analyzing an assembly of T. major remains, which were buried in volcanic ash in northeastern Nebraska around 12 million years ago, a team of researchers recently revealed that these rhinos lived relatively social and sedentary lives. In fact, as reported in a s ...read more

We’ve all been there: You’re hanging with a group of friends (either in real time or virtual), and one casually mentions doing something with the other — but neither explicitly mentions you. You’re faced with a dilemma. Inviting yourself when you’re not wanted could come off as intrusive at best, rude at worst. And not inviting yourself will leave you left out and feeling rejected.A new study now should put such anxieties to rest. In such situations, you’re more welcome than you thin ...read more

The Caspian Sea, considered the largest inland body of water on the planet, is shrinking. A new study published in the journal Communications Earth & Environment reports that as global temperatures rise, the Caspian Sea will start to go dry, critically impacting the people and animals that call this place home. Why Is the Caspian Sea Shrinking? According to the new study, the water sources that typically feed the sea are contributing less and less water. So much so that these sources canno ...read more
