Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel Prize-winning technology behind today's most precise
From chewing to chomping to grinding, teeth suffer from a lifetime of repeated mechanical stress. It makes sense, then, that enamel is one of the hardest natural materials.
When cells experience sudden physical stress, like stretching or pressure, they can activate a fast, protective mechanism that shields their nuclei from destruction, according to a new study published in the Biophysical Journal. This mechanism could help scientists develop
With help from a novel cross-linking molecule, MIT chemists have shown they can substantially improve the ballistic impact resistance of common polymers, including polystyrene and a type of rubber used to make shoe soles.
Bryozoans are tiny, filter-feeding colonial invertebrates that thrive in the world's oceans today, yet for decades their origins presented a puzzling gap in the fossil record. While nearly every other major animal group made its first appearance during the Cambrian explosion
Food waste is a nagging problem that weighs heavily on global food production, distribution and sales industries—but an emerging generation of AI sensors is providing a raft of fresh solutions. The embrace of AI in food industries has been swift, which is why Flinders
For generations, scientists believed a queen honeybee was made almost entirely by diet: feed an ordinary larva enough royal jelly and a ruler emerges. But new research suggests queens are created through a more elaborate process.
A new study on multiple genomes from the extinct cave lion has discovered that it represented a highly distinct evolutionary lineage, which separated from modern lions more than a million years ago. The results also show that the cave lion had a history of interbreeding with
Although it had a habit of interbreeding with modern lions The post Ancient DNA Illuminates the Uniqueness of the Extinct Cave Lion appeared first on Nautilus .
Queen-cell wax helps shape honeybee queen development, challenging the idea that royal jelly alone makes a queen, a new study suggests.
If your child has ever dug their heels in on the morning of the school athletics or cross country day, or refused to speak in front of the class, you're not alone.
Living in the Dead Sea would be a very unpleasant experience for most creatures. With salt concentration above 30% and temperatures ranging from 10–50°C, it takes unique environmental adaptations to survive in such harsh conditions.
It’s the first definitive proof of the angrite parent body The post Rare Meteorite Hints at Ancient Planetary Collision in Our Solar System appeared first on Nautilus .
