Early-nesting ducks at increased risk due to changes in climate, land use      (via sciencedaily.com)     Original source 

Each year approximately 10 million waterfowl fly north to their breeding grounds in the Prairie Pothole Region of North America, but the landscape that greets them has changed. Weather patterns and agricultural practices have significantly transformed the pothole-dotted native grasslands that waterfowl have used for thousands of years.

Elephant ecosystems in decline      (via sciencedaily.com)     Original source 

Global space for Asian elephant habitats has been in rapid decline since the 1700s, a new report reveals. More than 3 million square kilometers of the Asian elephant's historic habitat range has been lost in just three centuries and may underlie present-day conflicts between elephants and people.

Ant mounds are more important for biodiversity than previously thought      (via sciencedaily.com)     Original source 

The ant mounds on the heath, in the forest and in your garden are oases for life. The heat and nutrients from ant mounds make them the perfect home for unique plant and animal species, according to new research.

Male California sea lions are becoming bigger and better fighters as their population rebounds      (via sciencedaily.com)     Original source 

California sea lions have managed to maintain -- and, in the case of males, increase -- their average body size as their population grows and competition for food becomes fiercer. This is in contrast to other marine mammals, whose average body size tends to decrease as their numbers increase. Researchers report that sexual selection was a strong driving force for males to grow bigger and to strengthen muscles in their neck and jaw that help them fight for mates. Both male and female sea lions evaded food shortages by diversifying their diets and, in some cases, foraging further from the shore.

Speedy robo-gripper reflexively organizes cluttered spaces      (via sciencedaily.com)     Original source 

A new gripper robot grasps by reflex. Rather than start from scratch after a failed attempt, the bot adapts in the moment to reflexively roll, palm, or pinch an object to get a better hold.

Researchers explore techniques to successfully reintroduce captive birds into the wild      (via sciencedaily.com)     Original source 

Studies show that some species may require breeding in captivity within the next 200 years to avoid extinction. This reality places heavy importance on the reintroduction practices used to successfully transfer species from captivity to the wild. A new study looks at some of the most popular conservation techniques and identifies which have the highest likelihood of success for the reintroduction of bird species back into the wild.

Can jack-of-all-trades AI reshape medicine?      (via sciencedaily.com)     Original source 

Most medical AI models in use today are trained to perform one or two specific tasks and have limited utility. Next-generation AI -- called generalist medical AI -- incorporates various types of data to perform a variety of complex tasks in a range of clinical scenarios. Generalist medical AI can reshape medicine by augmenting clinical decision-making, real-time surgical and bedside support, and more.

Using microbes to get more out of mining waste      (via sciencedaily.com)     Original source 

Researchers have developed a new mining technique which uses microbes to recover metals and store carbon in the waste produced by mining. Adopting this technique of reusing mining waste, called tailings, could transform the mining industry and create a greener and more sustainable future.

Most massive touching stars ever found will eventually collide as black holes      (via sciencedaily.com)     Original source 

A new study looked at a known binary star (two stars orbiting around a mutual center of gravity), analyzing starlight obtained from a range of ground- and space-based telescopes. The researchers found that the stars, located in a neighboring dwarf galaxy called the Small Magellanic Cloud, are in partial contact and swapping material with each other, with one star currently 'feeding' off the other. They orbit each other every three days and are the most massive touching stars (known as contact binaries) yet observed.

Casting a safety net: A reliable machine learning approach for analyzing coalescing black holes      (via sciencedaily.com)     Original source 

An interdisciplinary team has developed an algorithm that immediately checks its own calculations of merging black holes' properties and corrects its result if necessary -- inexpensively and rapidly. The machine learning method provides very accurate information about the observed gravitational waves and will be ready for use when the global network of gravitational-wave detectors starts its next observing run in May.
