 An international team of astronomers reports the discovery of two new "super-Earth" exoplanets orbiting a nearby late-type M dwarf star. The newfound alien worlds, designated LP 890-9 b and LP 890-9 c, are slightly larger than the Earth. The finding has been published in Astronomy & Astrophysics. "Super-Earths" are planets more massive than Earth but not exceeding the mass of Neptune. Although the term "super-Earth" refers only to the mass of the planet, it is also used by astronomers to describe planets bigger than Earth but smaller than the so-called "mini-Neptunes" (with a radius between two to four Earth radii). Now, astronomers led by Laetitia Delrez of the University of Liège in Belgium, have discovered two new planets of the super-Earth class. They observed LP 890-9 a nearby M dwarf star of M6V spectral type, using NASA's Transiting Exoplanet Survey Satellite (TESS). This led to the discovery of the inner planet, which received de

             A male rock hyrax in the Ein Gedi Natural Reserve singing.

In male rock hyraxes,  singing  frequency and  rhythm  could be seen as indicators of individual quality by potential mates  signaling  information about their health and suitability as a partner. "We have been studying hyraxes for the past 20 years and have previously found several patterns in their songs that are common features of human language and music," said Dr. Vlad Demartsev, now a postdoctoral researcher in the Department of Biology at the University of Konstanz and the Max Planck Institute of Animal Behaviour, who collected the data for this study during their time at Tel

  The linear response theory developed in this work provides a full characterization of the relation between output and input signals (indicated by green and yellow arrows, respectively) in terms of the eigenmodes and the canonical states of the underlying non-Hermitian Hamiltonian. Credit: Ramy El-Ganainy Linear analysis plays a central role in science and engineering. Even when dealing with nonlinear systems, understanding the linear response is often crucial for gaining insight into the underlying complex dynamics. In recent years, there has been a great interest in studying open systems that exchange energy with a surrounding reservoir. In particular, it has been demonstrated that open systems whose spectra exhibit non-Hermitian singularities called exceptional points can demonstrate a host of intriguing effects with potential applications in building new lasers and sensors. At an exceptional point, two or modes become exactly identical. To better understand this, let us consider h

 Floods, droughts, and other water-related disasters are some of the costliest natural events that occur in Canada and around the world. Even with significant global advances in science and infrastructure designed to predict and manage such extreme disasters, many communities still face major societal and economic impacts when these events occur. In a new paper published in Nature, a team of University of Saskatchewan (USask) and international researchers presented their findings from a global investigation to determine gaps in science and policy that require reinforcement to better protect the world from droughts and floods. "Our flood and drought risk management paradigms are still based on the assumption that the past is representative of the future," said Dr. Saman Razav, Ph.D., an associate professor in USask's School of Environment and Sustainability, the Global Institute for Water Security (GIWS), and the College of Engineering in the department of civil, geologica

A new species of panda has been uncovered by scientists who state it is currently the last known and “most evolved” European giant panda. It lumbered through the forested wetlands of Bulgaria around six million years ago. Unearthed from the bowels of the Bulgarian National Museum of Natural History, two fossils of teeth originally discovered in the eastern European nation in the late 1970s, provide new evidence of a sizable relative of the modern giant panda. Unlike today’s iconic black and white bear, however, it was not purely reliant on bamboo for sustenance. “Although not a direct ancestor of the modern genus of the giant panda, it is its close relative,” explains the Museum’s Professor Nikolai Spassov, whose findings are publ
