Was the Peace River earthquake induced or natural? New study tests frameworks to answer the question
Using questionnaires created to determine whether a particular earthquake is natural or induced by human activity, a panel of experts concluded that the November 2022 magnitude 5.2 Peace River earthquake sequence in Alberta, Canada was likely induced.....»»
Biodiversity modeling advances to improve predictions of nature"s contributions to people
People depend on nature in a multitude of ways. Crop pollination, pest management, storm buffering, and carbon capturing are all part of nature's contributions to people (NCP). But these contributions are subject to change—species that make vital c.....»»
How "sleeping" microorganisms can determine the fate of a population
Microorganisms that temporarily "go to sleep" play an important role in the evolution and survival of a population. Mathematician Shubhamoy Nandan conducted research on the effect of this characteristic called "dormancy" in a novel mathematical model.....»»
Reassessing what we can expect from peptides in disease detection
Based on blood tests, it is possible to detect rare genetic diseases, recognize cancer, or determine the inflammation level in the body. Moreover, due to the rapid development of medical diagnostics based on biofluid analysis, many efforts are being.....»»

Astronomers calculate which exoplanets are most likely to have water
Astronomers know of about 60 rocky exoplanets orbiting in the habitable zones of their stars. When they try to determine how habitable these planets might be, detecting water in their atmospheres plays a huge role. But what if there was another way o.....»»
Engineers develop a way to determine how the surfaces of materials behave
Designing new compounds or alloys whose surfaces can be used as catalysts in chemical reactions can be a complex process relying heavily on the intuition of experienced chemists. A team of researchers at MIT has devised a new approach using machine l.....»»
Identifying the fish species present in a river based on traces of their DNA
As they swim around, fish leave DNA fragments behind them, for example via their skin or their excrements. Once collected and analyzed, these indicators allow scientists to determine all the species present in the environment. What's more, the method.....»»
Astronomers determine the age of three mysterious baby stars at the heart of the Milky Way
Through analysis of high-resolution data from a 10-meter telescope in Hawaii, researchers at Lund University in Sweden have succeeded in generating new knowledge about three stars at the very heart of the Milky Way. The stars proved to be unusually y.....»»
What Mars would look like from an orbiting space station
NASA's Mars Odyssey orbiter snapped unprecedented horizon images of the Red Planet, capturing clouds as well as a moon, Phobos. Imagine being in the International Space Station and looking at the world below — except instead of gazing dow.....»»
