UrduIn Physics of Fluids, researchers develop a model to explore the forces and flow structures created by penguin wings underwater. Penguin can adjust swimming posture by active wing feathering, pitching, and flapping and their dense, short feathers can also lock air between the skin and water to reduce friction and turbulence. The hydrodynamic model takes in information about the flapping and feathering of the wings and, using the immersed boundary method, solves for the motion of the wing and the thrust, lift, and lateral forces.

New Study Finds Emperor Penguins Increasingly Threatened by Climate Change
Woods Hole, MA (August 3, 2021) – A new study published today in Global Change Biology provides valuable new data that highlights how species extinction risk is accelerating due to rapid climate change and an increase in extreme climate events, such as glacial calving and sea ice loss. The study, led by Stephanie Jenouvrier, associate scientist, and seabird ecologist at Woods Hole Oceanographic Institution, and co-authored by an international team of scientists, policy experts, ecologists, and climate scientists, provided pivotal research and projections tailored for use by the U.S Fish & Wildlife Service (USFWS). Their work proposed that emperor penguins be listed as threatened under the Endangered Species Act and this week, USFWS submitted that listing proposal.
Emperor penguins, increasingly under siege by climate change, Proposed as threatened species under Endangered Species Act
Today, the U. S Fish and Wildlife Service (USFWS) announced a proposal to list the emperor penguin as a threatened species under the Endangered Species Act (ESA) based on evidence that the animal’s sea ice habitat is shrinking and is likely to continue to do so over the next several decades. Proposing a listing of threatened means the animal is at risk of becoming an endangered species–in danger of extinction–in the foreseeable future if its habitat continues to be destroyed or adversely changed.
