Pick up any physics textbook and you’ll find formula after formula that explains how things sway, fly, turn, and stop. The formula describes actions that we can observe, but behind each can be a series of factors that are not immediately apparent. Now, a new AI program developed by researchers at Columbia University appears to have found its own alternative physics. After being shown videos of physical phenomena on Earth, AI did not rediscover the current variables we used; instead, it actually comes up with a new variable to explain what it sees. To be clear, this does not mean that our current physics is flawed or that there is a more suitable model to explain the world around us. (Einstein’s laws have proven to be very powerful.) But they can only exist because they are built on a pre-existing ‘language’ of theories and principles established by centuries of tradition. Given an alternate timeline where other minds tackle the same problem from a slightly different perspective, wou

MIT scientists have created the first fully digitally produced plasma sensor to orbit a spacecraft. These plasma sensors, also known as retarding potential analyzers (RPAs), are used by satellites to determine the chemical composition and energy distribution of ions in the atmosphere. The 3D printing and laser cut hardware works and the advanced semiconductor plasma sensors are manufactured in a clean room, which makes them expensive and requires weeks of complex fabrication. In contrast, 3D printed sensors can be produced for tens of dollars in a matter of days. Due to their low cost and fast production, these sensors are ideal for CubeSats. These inexpensive, low-power, and lightweight satellites are often used for communications and environmental monitoring in the Earth’s upper atmosphere. The researchers developed RPA using a glass-ceramic material that is more durable than traditional sensor materials such as silicon and thin-film coatings. By using glass-ceramic in a fabricat

Over the past 10 years, researchers led by FU Qiaomei of the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences (CAS) have used ancient DNA (aDNA) technology to explore the history of ancient human populations, especially those in East Asia. . As part of their effort, the researchers reconstructed the entire genomes of two extinct groups of ancient humans—Neanderthals and Denisovans; map the history of migration and global population interactions; uncover the genetic structure of the oldest East Asian people; reveal adaptive genetic changes in East Asian Ice Age populations; and traces the formation of population patterns in northern and southern China and the origins of Austronesian populations in southern China. Recently, the FU team reviewed the development history of aDNA technology, discussed current technical barriers and solutions, and assessed the future of the technology. The study was published in Cell on July 21. The main

Penguins are no strangers to climate change. Their life history has been shaped by fluctuations in temperature, and their bodies are highly specialized for some of the most extreme conditions on Earth. However, scientists fear the penguin’s evolutionary path may have stalled, thanks to the lowest evolutionary rate ever detected in birds. An international team of researchers has just published one of the most comprehensive studies on penguin evolution to date, which is the first to integrate data from living and fossil penguin species. The research reveals a general chaotic penguin life history, with three-quarters of all known penguin species – now represented only by fossils – already extinct. “Over 60 million years, this iconic bird has evolved into a highly specialized marine predator, and is now well-adapted in some of the most extreme environments on Earth,” the authors wrote. “However, as their evolutionary history reveals, they now stand as guardians highlighting the vulnerabil

Water boils a lot – whether it’s a cup of tea brewed in the kitchen or a power station that generates electricity. Any increase in the efficiency of this process will have a major impact on the overall amount of energy used for it each day. One such improvement could come with newly developed treatments for surfaces involved in heating and evaporating water. The treatment improves the two main parameters that determine the boiling process: heat transfer coefficient (HTC) and critical heat flux (CHF). Most of the time, there is a trade-off between the two – when one improves, the other worsens. After years of investigation, the research term behind this technique has found a way to improve both. “Both parameters are important, but raising the two parameters together is a bit tricky because they have an intrinsic trade-off,” said bioinformatics scientist Youngsup Song of the Lawrence Berkeley National Laboratory in California. “If we have a lot of bubbles on the boiling surface, that

Mone Zaidi, MD, PhD, Director of the Center for Translational Medicine and Pharmacology and Professor of Medicine, and Pharmacological Sciences, at the Icahn School of Medicine at Mount Sinai, has received the 2022 International Research Award from the Austrian Bone and Mineral Society, Austria’s largest medical society. The International Research Prize is the most coveted prize in bone and mineral research and is awarded every three years. Since its inception in 1988, the International Research Prize has been awarded to individuals whose recent work in molecular, cellular, or materials science, or the pathophysiological or clinical aspects of bone and mineral metabolism, has resulted in new findings or concepts. . An international jury independently selected Dr. Zaidi was the prize winner, and he was awarded EUR 7,500 ($8,000 USD) at Osteoporoseforum, the 30 th The annual meeting of the Austrian Bone and Mineral Society, held in St. Wolfgang, Austria, June 23-25.
