A narwhal can grow a single 10-feet tooth through its upper lip; scientists used 3D X-rays and 3 particle accelerators to discover how nature's only straight tusk stays straight

An international team of biologists, chemists and physicists has used sophisticated 3D X-ray technology to investigate the tooth at an unprecedented level. A unicorn may be a mythical creature, but nature made something very similar under the Arctic ice. Wondering what? Well, the narwhal has a strange tusk that can reach nearly 10 feet long … Read more

Zebra mussel DNA detected in Utah’s Colorado River for first time, raising alarm over invasive species threat across the Upper Colorado River basin

An invasive species threat has reached a new stretch of the Colorado River, after scientists detected zebra mussel DNA in Utah’s portion of the river for the first time. The discovery has raised concerns among wildlife officials because zebra mussels can spread rapidly once established, potentially damaging infrastructure, disrupting recreation and altering freshwater ecosystems. The … Read more

In 1962, NASA loaded 22,900 gallons of water onto a Saturn I rocket and deliberately blew the container apart 65 miles above Earth to study what water would do in the upper atmosphere

Representative Image (AI-generated) For humans to travel deeper into space and remain there for months or even years, they will need much more than powerful rockets. Astronauts must have a continuous supply of oxygen, water and food, while waste and carbon dioxide must be carefully managed. On short missions, these needs can largely be met … Read more
