Could black holes help explain high-energy cosmic radiation? The universe is full of different types of radiation and particles that can be observed here on Earth. This includes photons across the entire range of the electromagnetic spectrum, from the lowest radio frequencies all the way to the highest-energy gamma rays. It also includes other particles such as neutrinos and cosmic rays, which race through the universe at close to the speed of light. Curiously, “cosmic rays” are not actually rays…
Norah Saarman receives American Mosquito Control Association Research Fund grant to develop improved species identification method Morphology is the study of the form and structure of organisms, including their physical characteristics such as shape, size and arrangement of parts. Morphology is key to taxonomy, the science of classifying organisms, as scientists use morphology to identify and study species, as well as to explore evolutionary processes. Identifying species is challenging — even with large animals and plants, says Utah State University…
From virtual reality to rehabilitation and communication, haptic technology has revolutionized the way humans interact with the digital world.

The standard model of particle physics is our best theory of the elementary particles and forces that make up our world: particles and antiparticles, such as electrons and positrons, are described as quantum fields. They interact through other force-fields, such as the electromagnetic force that binds charged particles. To understand the behaviour of these quantum fields and with that our universe, researchers perform complex computer simulations of quantum field theories. Unfortunately, many of these calculations are too complicated for even…
AI-enhanced IV nutrition for preemies Artificial intelligence can improve intravenous nutrition for premature babies, a Stanford Medicine study has shown. The study, which will publish March 25 in Nature Medicine, is among the first to demonstrate how an AI algorithm can enable doctors to make better clinical decisions for sick newborns. The algorithm uses information in preemies’ electronic medical records to predict which nutrients they need and in what quantities. The AI tool was trained on data from almost 80,000…
A new study co-led by Dartmouth researchers shows how radiation from black holes could have a nurturing effect on life. At the center of most large galaxies, including our own Milky Way, sits a supermassive black hole. Interstellar gas periodically falls into the orbit of these bottomless pits, switching the black hole into active galactic nucleus (AGN)-mode, blasting high-energy radiation across the galaxy. It’s not an environment you’d expect a plant or animal to thrive in. But in a surprising…

Plasmonic modulators are tiny components that convert electrical signals into optical signals in order to transport them through optical fibres. A modulator of this kind had never managed to transmit data with a frequency of over a terahertz (over a trillion oscillations per second). Now, researchers from the group led by Jürg Leuthold, Professor of Photonics and Communications at ETH Zurich, have succeeded in doing just that. Previous modulators could only convert frequencies up to 100 or 200 gigahertz – in…

A new analysis of data collected over three years by the Dark Energy Spectroscopic Instrument (DESI) collaboration provides even stronger evidence than the group’s previous datasets that dark energy, long thought to be a “cosmological constant,” might be evolving over time in unexpected ways. Dr. Mustapha Ishak-Boushaki, professor of physics at The University of Texas at Dallas, is co-chair of the DESI working group that interprets cosmological survey data gathered by the international collaboration, which includes more than 900 researchers…
A study published in JCAP places new limits on quantum gravity using data from the underwater detector KM3NeT Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the infinitely small. The solution to this puzzle might lie in the humble neutrino, an elementary particle with no electric charge and almost invisible, as it rarely interacts with matter, passing through everything on our…
American Gastroenterological Association guideline concludes that it is not clear whether computer-aided detection systems (CADe) for colonoscopy should be recommended for routine widespread use The American Gastroenterological Association (AGA) released a new clinical guideline making no recommendation — for or against — the use of computer-aided detection systems (CADe) in colonoscopy. A rigorous review of evidence showed that artificial intelligence-assisted technology helps identify colorectal polyps. However, its impact on preventing colorectal cancer — the third most common cancer worldwide —…
Knowing from what debris field in the asteroid belt our meteorites originate is important for planetary defense efforts against Near Earth Asteroids. Where do meteorites of different type come from? In a review paper in the journal Meteoritics & Planetary Science, published online this week, astronomers trace the impact orbit of observed meteorite falls to several previously unidentified source regions in the asteroid belt. “This has been a decade-long detective story, with each recorded meteorite fall providing a new clue,”…
