Marine animals ingest microplastic particles and excrete them in their feces, posing a risk to the marine environment
Professor Schenker on a research dive. Credit: Dr. Tom Schlesinger. A new study from Tel Aviv University reveals alarming findings about the spread of microplastic particles in marine food webs. In recent years, numerous studies have investigated the dangers of marine animals, and more specifically filter feeders, ingesting non-degradable microplastic particles. In this study, the researchers sought to understand how…

Breeding success: London Zoo counts animals one by one
Last year, 11 chicks and five new adults were born, and keepers are able to recognize each Humboldt penguin individually. Armed with tons of lettuce and buckets of nuts, London Zoo began its annual animal count on Friday, ushering everything from goats to gorillas out of their enclosures for a monumental inventory. The nearly two-century-old zoo holds a nearly week-long…

Scientists uncover insights into neuron function by measuring two key signals simultaneously in living animals
When triggered by odor, C. elegans olfactory neurons undergo rapid changes in membrane potential and intracellular calcium ion levels, leading to fluctuations in the fluorescence intensity of membrane potential sensors and calcium ion sensors. Researchers at Kyushu University measured these changes simultaneously using high-speed capture under a microscope and subsequent image processing, showing that the two signals encode different information…

5 animals that behave differently under the moonlight
Credit: CC0 Public Domain Once every spring, a few days after a full moon, Great Barrier Reef corals simultaneously release eggs and sperm. This phenomenon is so spectacular that it can be seen from space. Not only does the moon’s gravitational pull interact with the sun to cause tidal ebbs and flows (ebbs and flows), but the moon’s orbit around…
