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.

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.

Polymer power: Researchers enhance the safety of lithium batteries      (via sciencedaily.com)     Original source 

Lithium-ion batteries face safety concerns as a result of internal separator issues which often lead to short circuits. Scientists have now developed a method to improve the stability and properties of separators with a layer of silicon dioxide and other functional molecules. Batteries employing these separators demonstrated improved performance and reduced growth of disruptive root-like structures, paving the way for high-safety batteries that can aid the adoption of electric vehicles and advanced energy storage systems.

Liquid lithium on the walls of a fusion device helps the plasma within maintain a hot edge      (via sciencedaily.com)     Original source 

Emerging research suggests it may be easier to use fusion as a power source if liquid lithium is applied to the internal walls of the device housing the plasma. Past experiments studied solid lithium coatings and found they could enhance a plasma. The researchers were pleased they could yield similar results with liquid lithium, as it's better suited for use in a large-scale tokamak.

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.
