Poultry scientists develop 3D anatomy technique to learn more about chicken vision      (via sciencedaily.com)     Original source 

Poultry scientists are unraveling the complexities of bird brains and finding less expensive ways to do it. The scientists mapped the intricate neurological pathways that control vision in chickens with detailed 3D models of the connections between the eyes and four regions of the brain.

A non-allergenic wheat protein for growing better cultivated meat      (via sciencedaily.com)     Original source 

As the world's population increases, cultivated or lab-grown meat -- animal muscle and fat cells grown in laboratory conditions -- has emerged as a potential way to satisfy future protein needs. And edible, inexpensive plant proteins could be used to grow these cell cultures. Now, researchers report that the non-allergenic wheat protein glutenin successfully grew striated muscle layers and flat fat layers, which could be combined to produce meat-like textures.

Moth keeps a firm eye on the proboscis      (via sciencedaily.com)     Original source 

Just as when we humans reach for objects, the hummingbird hawk moth uses its visual sense to place its long proboscis precisely on a flower to search for nectar, according to biologists. This is why the moth is a great model organism for research into the visual control of appendages.

Endangered seabird shows surprising individual flexibility to adapt to climate change      (via sciencedaily.com)     Original source 

New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought.

How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle      (via sciencedaily.com)     Original source 

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out how flowing fluids exert forces and move structures, thereby revealing the answer to this long-standing mystery.

Researchers map genome for cats, dolphins, birds, and dozens of other animals      (via sciencedaily.com)     Original source 

Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.

New method flips the script on topological physics      (via sciencedaily.com)     Original source 

The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable -- and above all reliable -- properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. Researchers have demonstrated a model-free method for identifying topology, enabling the discovery of new topological materials using a purely experimental approach.

Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness      (via sciencedaily.com)     Original source 

How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.

Live animal transport regulations not 'fit for purpose', major international study finds      (via sciencedaily.com)     Original source 

A 'fitness check' of regulations in five countries meant to protect animals during transportation, has deemed that they all fall short of fully protecting animals during transport. Findings from this interdisciplinary work involving animal welfare scientists and a law lecturer which compared animal transport rules designed to protect the billions of livestock that are transported on lengthy journeys in Australia, Canada, New Zealand, EU (including UK) and US, highlights serious failures.

Marine heat waves trigger shift in hatch dates and early growth of Pacific cod      (via sciencedaily.com)     Original source 

Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study shows. These changes in the hatch cycle and early growth patterns persisted in years following the marine heat waves, which could have implications for the future of Gulf of Alaska Pacific cod, an economically and culturally significant species.

New research into hedgehogs injured by robotic lawn mowers discovers a significant but solvable animal welfare and conservation problem      (via sciencedaily.com)     Original source 

Scientists analyzed 370 documented cases of hedgehogs being injured (cut) by electric gardening tools in Germany. Almost half of the hedgehogs found between June 2022 and September 2023 did not survive the injuries. The data reveal a serious animal welfare and conservation issue for these specially protected animals, as most hedgehogs were only found hours or even days after the accidents.
