Published Self-supervised AI learns physics to reconstruct microscopic images from holograms
(via sciencedaily.com) Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.
Published AI transformation of medicine: Why doctors are not prepared
(via sciencedaily.com) The success of artificial intelligence technologies depends largely on how physicians interpret and act upon a tool's risk predictions -- and that requires a unique set of skills that many are currently lacking, according to a new perspective article.
Published Modified virtual reality tech can measure brain activity
(via sciencedaily.com) The research team at The University of Texas at Austin created a noninvasive electroencephalogram (EEG) sensor that they installed in a Meta VR headset that can be worn comfortably for long periods. The EEG measures the brain's electrical activity during the immersive VR interactions.
Published Deep learning for new protein design
(via sciencedaily.com) Deep learning methods have been used to augment existing energy-based physical models in 'do novo' or from-scratch computational protein design, resulting in a 10-fold increase in success rates verified in the lab for binding a designed protein with its target protein. The results will help scientists design better drugs against diseases like cancer and COVID-19.
Published Denial of service threats detected thanks to asymmetric behavior in network traffic
(via sciencedaily.com) Scientists have developed a better way to recognize denial-of-service internet attacks, improving detection by 90 percent.
Published New method simplifies the construction process for complex materials
(via sciencedaily.com) A new technique incorporates many different building blocks of cellular metamaterials into one unified graph-based representation. This can be used to make a user-friendly interface that can quickly and easily model metamaterials, edit the structures, and simulate their properties.
Published Thermal imaging innovation allows AI to see through pitch darkness like broad daylight
(via sciencedaily.com) Engineers have developed HADAR, or heat-assisted detection and ranging.
Published Google and ChatGPT have mixed results in medical informatiom queries
(via sciencedaily.com) Computer scientists found that queries for medical information about dementia disease on ChatGPT provided more objective results than similar queries on Google, but both services have strengths and weaknesses. Google provided the most current information, but the query results are skewed by service and product providers seeking customers, the researchers found. ChatGPT, meanwhile, provides more objective information, but it can be outdated and lacks the sources of its information in its narrative responses.
Published That's funny -- but AI models don't get the joke
(via sciencedaily.com) Using hundreds of entries from the New Yorker magazine's Cartoon Caption Contest as a testbed, researchers challenged AI models and humans with three tasks: matching a joke to a cartoon; identifying a winning caption; and explaining why a winning caption is funny.
Published 3D display could soon bring touch to the digital world
(via sciencedaily.com) Engineers have designed a new, shape-shifting display that can fit on a card table and allows users to draw 3D designs and more.
Published Researchers successfully train a machine learning model in outer space for the first time
(via sciencedaily.com) Original source Scientists have trained a machine learning model in outer space, on board a satellite. This achievement could revolutionize the capabilities of remote-sensing satellites by enabling real-time monitoring and decision making for a range of applications.
Published Reinforcement learning allows underwater robots to locate and track objects underwater
(via sciencedaily.com) A team has shown that reinforcement learning -i.e., a neural network that learns the best action to perform at each moment based on a series of rewards- allows autonomous vehicles and underwater robots to locate and carefully track marine objects and animals.
Published Breakthrough in Monte Carlo computer simulations
(via sciencedaily.com) Researchers have developed a highly efficient method to investigate systems with long-range interactions that were previously puzzling to experts. These systems can be gases or even solid materials such as magnets whose atoms interact not only with their neighbors but also far beyond.
Published Why computer security advice is more confusing than it should be
(via sciencedaily.com) If you find the computer security guidelines you get at work confusing and not very useful, you're not alone. A new study highlights a key problem with how these guidelines are created, and outlines simple steps that would improve them -- and probably make your computer safer.
Published Detecting threats beyond the limits of human, sensor sight
(via sciencedaily.com) Original source A new patented software system can find the curves of motion in streaming video and images from satellites, drones and far-range security cameras and turn them into signals to find and track moving objects as small as one pixel. The developers say this system can enhance the performance of any remote sensing application.
Published Dreaming in technicolor
(via sciencedaily.com) Original source A team of computer scientists and designers has developed a tool to help people use color better in graphic design.
Published How urea may have been the gateway to life
(via sciencedaily.com) Original source Urea reacts extremely quickly under the conditions that existed when our planet was newly formed. This new insight furthers our understanding of how life on Earth might have begun.
Published There may be good news about the oceans in a globally warmed world
(via sciencedaily.com) Original source An analysis of oxygen levels in Earth's oceans may provide some rare, good news about the health of the seas in a future, globally warmed world. A study analyzing ocean sediment shows that ocean oxygen levels in a key area were higher during the Miocene warm period, some 16 million years ago when the Earth's temperature was hotter than it is today.
Published What math can teach us about standing up to bullies
(via sciencedaily.com) Original source New research from Dartmouth takes a fresh look at game theory to show that being uncooperative can help people on the weaker side of a power dynamic achieve a more equal outcome -- and even inflict some loss on their abusive counterpart. The findings can be applied to help equalize the balance of power in labor negotiations, international relations and everyday interactions, as well as integrate cooperation into interconnected AI systems such as driverless cars.
Published Research in a place where geological processes happen before your eyes
(via sciencedaily.com) Original source Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant earthquakes, the region experiences about four typhoons per year on average, and in some places, it receives upwards of several meters of rain annually.
