Cracking open a tasty menu for captive marsupials to sink their teeth into      (via sciencedaily.com)     Original source 

From sifting through topsoil for native truffles to cracking open hard shells of seeds and nuts to munch on the tasty kernels, Australia bettongs and potoroos are described as 'ecosystem engineers' in a two-way relationship between their rich diet and environmental health. However, with native ecosystems and potoroid marsupial numbers in decline, ecology and evolution experts are working to understand how difficult it is to bite into the foods these leading foragers seek out.

Researchers fabricate ultrastrong aluminum alloys for additive manufacturing      (via sciencedaily.com)     Original source 

Material engineers have created a patent-pending process to develop ultrahigh-strength aluminum alloys that are suitable for additive manufacturing because of their plastic deformability. They have produced the alloys by using several transition metals that traditionally have been largely avoided in the manufacture of aluminum alloys.

Restored oyster sanctuaries host more marine life      (via sciencedaily.com)     Original source 

Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.

A 2D device for quantum cooling      (via sciencedaily.com)     Original source 

Engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, which require extremely low temperatures to function optimally.

Blue and great tits deploy surprisingly powerful memories to find food      (via sciencedaily.com)     Original source 

Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.

Spotted apex predator being pressured by spotted pack hunters -- and it's our fault      (via sciencedaily.com)     Original source 

Leopards, who are already in decline, can't keep up with hyenas when people are around. As we humans move into the their territories more and more, we are helping to disturb and unbalance ecosystems. This has been shown in a new study where researchers used camera traps to observe both large carnivore species.

Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive      (via sciencedaily.com)     Original source 

Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.

The evidence is mounting: humans were responsible for the extinction of large mammals      (via sciencedaily.com)     Original source 

Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
