Scientists have been puzzling over how to tell male dinosaurs from females for ages. Now, a fresh study from a team in Northern Ireland might have found a clue hidden in some unexpected places: healed fractures in dinosaur tails. These injuries could be the result of rough mating, where male dinosaurs might have been a bit too enthusiastic. The researchers focused o...
The human body is a symphony of rhythms. From the steady beat of the heart to the ebb and flow of sleep, these rhythms keep us ticking. Now, scientists have uncovered a surprising link between the gut and the brain. Researchers at the University of California San Diego have found that the gut's rhythmic muscle movements might hold the key to understanding how blood v...
The JUICE mission, headed to Jupiter, has a surprising chance to study a rare comet. This mission aims to explore Jupiter's icy moons, Ganymede, Callisto, and Europa, which may have hidden oceans and potential for life. Ganymede, the largest moon, is unique with its own magnetic field, and JUICE will be the first spacecraft to orbit it. JUICE is on a slow journey to...
Pregnancy can bring a lot of pain. Some moms try different things to feel better. One mom tried snorting Tylenol. She heard about it at a party. Pregnant women used mirrors and rolled-up bills to snort the medicine. It made them feel good fast. Soon, she did this often in her third trimester. This mom's son has autism. She thinks the Tylenol might have caused it. Bu...
Chimpanzees have always been fascinating creatures, showing behaviors that remind us of humans. They can get tipsy, follow trends, and now, they've shown they can think rationally too. A group of scientists from the Netherlands wanted to see if chimps could change their minds when they see new evidence. They did some tests at a chimpanzee sanctuary in Uganda. The ch...
China just sent a new crew to its space station, Tiangong. This mission, called Shenzhou-21, is pretty special. It's carrying three astronauts, or taikonauts as China calls them, and something even more unusual: four live mice. This is the first time China has sent mammals to space. The crew includes Zhang Lu, who's been to space before, and two newbies, Wu Fei and ...
Bowhead whales are amazing creatures. They live in the cold Arctic waters. These whales are the longest-living mammals on Earth. Some can live up to 268 years! That's way longer than any human. Scientists have been studying these whales. They found something interesting. Bowhead whales are really good at fixing damaged DNA. This helps them stay healthy for a very lo...
In the Chernobyl Exclusion Zone, a group of stray dogs has captured attention not just for their survival skills, but also for their striking blue fur. This unusual coloration is thought to be due to chemical exposure, possibly from a leaking portable toilet, rather than radiation. The dogs, descendants of pets left behind during the 1986 nuclear disaster, have becom...
In the 1950s, something strange was happening in the sky. Pictures taken by the Palomar Observatory showed quick, bright flashes that didn't look like anything natural. These flashes, called "transients, " appeared more often after nuclear tests. This isn't just a wild guess—it's backed by data. Researchers looked at over 100, 000 old photos and found that these fla...
The Mayans, a brilliant ancient civilization from Central America, were ahead of their time in astronomy and math. They could predict solar eclipses with surprising precision. But how did they do it? Recent studies offer some answers. A key piece of evidence is the Dresden Codex, a famous Mayan astronomical record. Researchers zoomed in on its eclipse prediction tab...
