Your Butt Is Getting in the Way of Science

The Body’s Most Embarrassing Organ Is an Evolutionary Marvel Katherine J. Wu © Provided by The Atlantic Arne Svenson, Stray #55 To peer into the soul of a sea cucumber, don’t look to its face; it doesn’t have one. Gently turn that blobby body around, and gaze deep into its marvelous, multifunctional anus. The sea cucumber s posterior is so much more than an exit hole for digestive waste. It is also a makeshift mouth that gobbles up bits of algae; a faux lung, latticed with tubes that exchange gas with the surrounding water; and a weapon that, in the presence of danger, can launch a sticky, stringy web of internal organs to entangle predators. It can even, on occasion, be a home for shimmering pearlfish, which wriggle inside the bum when it billows open to breathe. It would not be inaccurate to describe a sea cucumber as an extraordinary anus that just so happens to have a body around it. As Rebecca Helm, a jellyfish biologist at the University of North

Planet Earth Report -- Biological Fukushima Threatens the Planet to Mutation that Rewired the Human Mind

Cosmic census reveals 540 stars and planets in our neighborhood, reports New Scientist. –Using existing databases of objects alongside data from the European Space Agency’s Gaia telescope, which is mapping billions of stars in our galaxy, Céline Reylé at the UTINAM Institute in France and her colleagues pooled all knowledge of objects within 10 parsecs, or 33 light years, of our sun.” How Long Can We Live? asks Ferris Jabr for The New York Times Magazine. New research is intensifying the debate with profound implications for the future of the planet–“As the global population approaches eight billion, and science discovers increasingly promising ways to slow or reverse aging in the lab, the question of human longevity’s potential limits is more urgent than ever. When their work is examined closely, it’s clear that longevity scientists hold a wide range of nuanced perspectives on the future of humanity.”

Life on the surface of the ocean

Image sourced from Helm (2021) - Dr Anjani Ganase reveals the intricate web of life that exists between water and air off our shores As budding marine biologists, some of our first introductions to the ocean did not include exciting encounters on exotic reefs or swimming with dolphins. Rather we were introduced to the very top layer of the ocean and the marine creatures that lived near the surface of the water. These creatures are referred to as a neuston community. Neuston is a Greek word for “to swim” and “to float”. Skimming a net along the surface of the water, we would find a collection of transparent shapes and drifting forms that were larvae of fish and invertebrates and other marine critters. In her recent publication, Rebecca Helm, assistant professor at the University of North Carolina,
