Groundbreaking study reveals oceanic seabirds chase tropical cyclones      (via sciencedaily.com)     Original source 

A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.

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.

Life underground suited newly discovered dinosaur fine      (via sciencedaily.com)     Original source 

A newly discovered ancestor of Thescelosaurus shows evidence that these animals spent at least part of their time in underground burrows. The new species contributes to a fuller understanding of life during the mid-Cretaceous -- both above and below ground.

Scientists discover how to improve vaccine responses to potentially deadly bacterium      (via sciencedaily.com)     Original source 

Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.

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.

Brain size riddle solved as humans exceed evolution trend      (via sciencedaily.com)     Original source

Migrating starlings are no copycats      (via sciencedaily.com)     Original source 

Young, na ve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a classic 'displacement' experiment and by adding new data, a team of researchers have settled a long-lasting debate.

Not so selfish after all: Viruses use freeloading genes as weapons      (via sciencedaily.com)     Original source 

Certain pieces of DNA have been labeled as 'selfish genetic elements' due to notions that they don't contribute to a host organism's survival. Instead, researchers have now discovered that these elements have been weaponized and play a crucial role by cutting off a competitor's ability to reproduce.

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.

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.
