Ancient Crinoids Hide Buckminsterfullerene-Like Spheres in Their Skeletons

Researchers found spherical, ball-like skeletal arrangements in 80-million-year-old crinoid fossils (Marsupites testudinarius and Uintacrinus socialis) that resemble buckminsterfullerene structures, suggesting these shapes helped with protection and buoyancy in predator-rich ancient oceans. The design appears across wide fossil deposits but vanished in later species, leaving scientists with questions about why the form disappeared.

Superhydrophobic tubes stay afloat, even when punctured

Researchers at the University of Rochester have etched aluminum tubes to create micro- and nano-pits that render the surface superhydrophobic. When placed in water, the tubes trap a stable air bubble and stay buoyant even if heavily damaged; a middle divider keeps the bubble in place, enabling linked tubes to form rafts for ships, buoys, and floating platforms with potential renewable-energy applications.

"Unusual Angelfish's CT Scan Reveals Surprising Swim Behavior"

A French angelfish at the Denver Zoo was swimming with a tilt, prompting a visit to the on-site hospital for a CT scan. The scan revealed that the fish had inflamed intestines, causing increased internal gas and affecting its buoyancy. The fish was treated with antibiotics and is now swimming normally.

Mass vs. Weight: Understanding the Difference.

Mass and weight are related but separate concepts in physics. Mass is an intrinsic property of an object, while weight is the force exerted on an object's matter by a gravitational field. The equivalence principle states that gravitational mass and inertial mass are equivalent. Buoyancy explains why floating objects still have weight, as they displace fluid and experience an upthrust equal to the weight of the fluid displaced. The weight of an object is spread out across the planet's atmosphere when it flies, making it difficult to measure.
