MIT and Technion researchers have developed an adaptive algorithm that optimizes machine learning by combining imitation and reinforcement learning. The algorithm autonomously decides when to follow or diverge from a teacher model, improving training efficiency and effectiveness. This approach presents a potential way to improve training for complex tasks and could potentially be used with … Read more
The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) is using pioneering techniques to search for extraterrestrial intelligence (SETI) within the Milky Way. The team developed software based on a Fast Folding Algorithm (FFA), a search method that offers enhanced sensitivity to periodic sequences of narrow pulses. This approach is aimed at detecting repeating patterns … Read more
Majorana particles, named after the Italian physicist Ettore Majorana, are fascinating entities in the field of particle physics. They are unique because they possess the remarkable property of being their own antiparticles. These elusive particles have the potential to revolutionize quantum computing and contribute to the understanding of fundamental physics, offering exciting possibilities for the … Read more
The research team worked with organoids derived from untreated cancer tissue taken from patients. Credit: UNIGE A team from the University of Geneva (UNIGE) has devised a novel method for customizing treatments by testing them on artificial tumors. Determining the optimal treatment for colon cancer can be challenging as each patient’s response to chemotherapy varies … Read more
Botox, short for botulinum toxin, is a neurotoxic protein derived from the bacterium Clostridium botulinum. It is widely known for its use in cosmetic procedures to reduce the appearance of wrinkles by temporarily paralyzing facial muscles. Professor Frederic Meunier and Dr. Merja Joensuu, affiliated with the Queensland Brain Institute at The University of Queensland, have … Read more
Artist’s impression of the Cassini spacecraft flying through plumes erupting from the south pole of Saturn’s moon Enceladus. These plumes are much like geysers and expel a combination of water vapor, ice grains, salts, methane, and other organic molecules.

Artist’s impression of an aurora and the surrounding radiation belt of the ultracool dwarf LSR J1835+3259. Credit: Chuck Carter, Melodie Kao, Heising-Simons Foundation High-resolution imaging of radio emissions from an ultracool dwarf shows a double-lobed structure like the radiation belts of Jupiter. A team of astronomers has successfully observed the first radiation belt outside our … Read more
Scientists have conducted laboratory experiments at the National Ignition Facility at Lawrence Livermore National Laboratory that generated the extreme compressions necessary for pressure-driven ionization. Their research provides new insights for atomic physics at gigabar pressures, which benefits astrophysics and nuclear fusion research.

Vaping, a popular alternative to traditional smoking, involves inhaling and exhaling aerosol produced by e-cigarettes. While it is promoted as a safer option, especially for adults trying to quit smoking, concerns have arisen regarding its impact on children. The accessibility and enticing flavors of vaping products have led to an alarming increase in underage usage, … Read more
Layers of Earth’s atmosphere are shown in a view looking across Earth’s surface from the International Space Station. Credit: NASA New research by Lawrence Livermore National Laboratory scientists reveals that human activities are undeniably altering the thermal structure of Earth’s atmosphere. By expanding climate “fingerprinting” to the mid-to upper stratosphere, the team has improved the … Read more
