Invading mole rats found to kidnap pups from conquered colonies

A trio of researchers with Washington University St. Louis, the Columbia River Inter-tribal Fish Commission and San Francisco State University has found that invading mole rats at times kidnap pups from the colonies they conquer. In their paper published in the Journal of Zoology, Stan Braude, Jon Hess and C. Ingram describe their decade-long study of mole rats in Kenya’s Meru National Park and what they learned about their efforts to expand colony size.

Trees bring benefits to society, regardless of their origin

Trees planted in urban spaces provide a multitude of ecosystem services: they reduce air pollution and noise, provide habitat and shelter for other species, and reduce erosion during heavy rains. They also offer opportunities for relaxation, attenuate urban heat islands and contribute both to landscapes and a sense of place. At the same time, trees can be a source of allergens, generate maintenance costs and cause accidents or threats to native biodiversity if introduced from elsewhere.

Order up! AI finds the right material

Engineers are always looking for materials with very specific properties for their projects. Unfortunately, there are way too many options for researchers to simply guess-and-check until they find what they’re looking for. Even if they were to simulate materials, instead of testing them in the lab, it would take far too long to find a suitable material.

A new interpretation of quantum mechanics suggests that reality does not depend on the person measuring it

Quantum mechanics arose in the 1920s, and since then scientists have disagreed on how best to interpret it. Many interpretations, including the Copenhagen interpretation presented by Niels Bohr and Werner Heisenberg, and in particular, von Neumann-Wigner interpretation, state that the consciousness of the person conducting the test affects its result. On the other hand, Karl Popper and Albert Einstein thought that an objective reality exists. Erwin Schrödinger put forward the famous thought experiment involving the fate of an unfortunate cat that aimed to describe the imperfections of quantum mechanics.

NASA’s TESS creates a cosmic vista of the northern sky

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered 74 exoplanets, or worlds beyond our solar system. Astronomers are sifting through some 1,200 additional exoplanet candidates, where potential new worlds await confirmation. More than 600 of these candidates lie in the northern sky.
