We've Been Misreading a Major Law of Physics For The Last 300 Years. When Isaac Newton inscribed onto parchment his now-famed laws of motion in 1687, he could have only hoped we'd be discussing them three centuries later. Writing in Latin, Newton outlined three universal principles describing how the motion of objects is …More recently, in 2021, researchers developed an ultra-thin magnetic material just one atom thick. Not only could its magnetic intensity be fine-tuned for the purposes of quantum computing, but it also works at room temperature. The study has been published in Applied Physics Letters. Quantum behavior is a strange, fragile thing that …The dorsal raphe area of the brain, imaged using confocal microscopy. ( Spitzer Lab, UC San Diego) They found that a severe fright sort of flipped a switch in the neurons, changing the neurotransmission mechanism from glutamate, which excites neurons, to GABA, which inhibits neuronal activity. The switch appears to sustain a fear …Jun 1, 2022 · The author of a new research article in the International Journal of Astrobiology says that ETCs may not need starships to escape existential threats and travel to another star system. They could instead use free-floating planets, also known as rogue planets. The article is "Migrating extraterrestrial civilizations and interstellar colonization ... An international team of astronomers flipped it again in 2018 and found that a planetary nebula is indeed the most likely solar corpse. The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the ...

4 days ago · Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives. Never-before-seen ratios of particles making up atomic nuclei have emerged in a landmark experiment involving the fragmentation of heavy elements. By breaking apart the nuclei of platinum, physicists led by Oleg Tarasov of Michigan State University have discovered new isotopes of rare-Earth elements thulium, ytterbium, and lutetium. A new kind of black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing.. Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists has observed the equivalent of what we call Hawking radiation – particles born from disturbances in the quantum fluctuations caused by the black hole's break ...

Research into ancient geological events suggests that our planet has a slow, steady 'heartbeat' of geological activity every 27 million years or so. This pulse of clustered geological events – including volcanic activity, mass extinctions, plate reorganizations, and sea level rises – is incredibly slow, a 27.5-million-year cycle of ...

Scientists have known about these plant defenses since the 1980s, detecting them in over 80 plant species since then. Now, a team of Japanese researchers has deployed real-time imaging techniques to reveal how plants receive and respond to these aerial alarms.
