By-the-wind sailor jellies wash ashore in massive numbers after warmer winters

Observations by citizen scientists help researchers find patterns in jellyfish strandings Velella velella, also called “by-the-wind sailor” jellies, washed ashore at Moolack Beach, Oregon. As their name suggests, by-the-wind sailor jellyfish know how to catch a breeze. Using a stiff, translucent sail propped an inch above the surface of the ocean, these teacup-sized organisms skim along the water, dangling a fringe of delicate purple tentacles just below the surface to capture zooplankton and larval fish as they travel. At the mercy of the wind, these jellies, sometimes numbering in the trillions, can wash ashore on beaches around the world, including up and down the U.S. West Coast, in what is called a stranding event. While these mass stranding events are hard to miss, very little is known about how or why they happen.

Skin deep: Aquatic skin adaptations of whales and hippos evolved independently

Credit: Carl Buell A new study shows that the similarly smooth, nearly hairless skin of whales and hippopotamuses evolved independently. The work suggests that their last common ancestor was likely a land-dwelling mammal, uprooting current thinking that the skin came fine-tuned for life in the water from a shared amphibious ancestor. The study is published today in the journal Current Biology and was led by researchers at the American Museum of Natural History; University of California, Irvine; University of California, Riverside; Max Planck Institute of Molecular Cell Biology and Genetics; and the LOEWE-Centre for Translational Biodiversity Genomics (Germany). How mammals left terra firma and became fully aquatic is one of the most fascinating evolutionary stories, perhaps rivaled only by how animals traded water for land in the first place or by the evolution of flight, said John Gatesy, a senior research scientist in the American Museum of Natural History s Division of Verte

We need to strengthen and accelerate US science and technology progress

We need to strengthen and accelerate US science and technology progress Sethuraman Panchanathan, opinion contributor © The Hill We need to strengthen and accelerate US science and technology progress For the past year, the public has looked to the science community to develop countermeasures for COVID-19, from models of the virus structure and how it spreads, to novel tests and treatments. Researchers have risen to the occasion, as exemplified by vaccines produced at a speed faster than many thought possible. But our job is far from done. Americans will depend on scientists for new technologies to help us navigate this pandemic and recover from it, for innovations that can help our economy bounce back, and for solutions to other critical issues facing our country, such as racial equity and climate change.
