Polar orbits are favoured for their ability to map the entire Earth's surface over time, making them critical for weather monitoring, climate research, and reconnaissance. Listen to Story Polar orbits ...

Polar sea ice has reached record, and near-record, lows for this time of year, pushing the pace of global warming and alarming scientists. The just declared 2025 Arctic sea ice extent winter ...

SOME cilia and flagella beat in a complex three-dimensional manner, and, in addition, the angular velocity at the tip is greater than at the base. Presumably the bundle of fibrils which make up a ...

SpaceX's mission to launch the first astronauts into polar orbit is quickly approaching. Named for the Norwegian seafaring ship Fram, which completed expeditions of the Arctic and Antarctic ...

A new study reported on by the Guardian has confirmed what climate scientists have feared for years: Earth's glaciers are melting at a record-breaking pace. Glaciers worldwide are vanishing at an ...

PHYSICOCHEMICAL characterization of components of flagella and cilia is essential for an understanding of the mechanisms underlying flagellar and ciliary movement. The so-called “9 + 2” fibres ...

Fungi in some Divisions produce mobile spores (zoospores) with filamentous asexual appendages called flagella. There are two types of flagellum: a smooth flagellum is called a whiplash flagellum; and, ...

Kleiber’s law, or the 3/4 -power law scaling of the metabolic rate with body mass, is considered one of the few quantitative laws in biology, yet its physiological basis remains unknown. Here, we ...
