Published To help autonomous vehicles make moral decisions, researchers ditch the 'trolley problem'
(via sciencedaily.com) Original source Researchers have developed a new experiment to better understand what people view as moral and immoral decisions related to driving vehicles, with the goal of collecting data to train autonomous vehicles how to make 'good' decisions. The work is designed to capture a more realistic array of moral challenges in traffic than the widely discussed life-and-death scenario inspired by the so-called 'trolley problem.'
Published A new possible explanation for the Hubble tension
(via sciencedaily.com) Original source The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values. This so-called 'Hubble tension' poses a puzzle for cosmologists. Researchers are now proposing a new solution: Using an alternative theory of gravity, the discrepancy in the measured values can be easily explained -- the Hubble tension disappears.
Published Brainstorming with a bot
(via sciencedaily.com) Original source Electronic nanomaterials experts have imagined how recent advances in artificial intelligence (AI) and machine learning (ML) could aid scientific brainstorming and ideation. To accomplish this, they have developed a chatbot with knowledge in the kinds of science he's been engaged in.
Published Scientists build tiny biological robots from human cells
(via sciencedaily.com) Original source Scientists have created tiny moving biological robots from human tracheal cells that can encourage the growth of neurons across artificial 'wounds' in the lab. Using patients' own cells could permit growth of Anthrobots that assist healing and regeneration in the future with no nead for immune suppression.
Published Genomic study sheds light on how carnivorous Asian pitcher plants acquired signature insect trap
(via sciencedaily.com) Original source Scientists sequenced the genome of the East Asian pitcher plant, Nepenthes gracilis, a species of carnivorous plant related to Venus flytraps, as well as sundews, beets and spinach.
Published Discovery of planet too big for its sun throws off solar system formation models
(via sciencedaily.com) Original source The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems.
Published Scientists use A.I.-generated images to map visual functions in the brain
(via sciencedaily.com) Original source Researchers have demonstrated the use of AI-selected natural images and AI-generated synthetic images as neuroscientific tools for probing the visual processing areas of the brain. The goal is to apply a data-driven approach to understand how vision is organized while potentially removing biases that may arise when looking at responses to a more limited set of researcher-selected images.
Published 2D material reshapes 3D electronics for AI hardware
(via sciencedaily.com) Original source Researchers demonstrated monolithic 3D integration of layered 2D material into novel processing hardware for artificial intelligence computing. The new approach provides a material-level solution for fully integrating many functions into a single, small electronic chip -- and paves the way for advanced AI computing.
Published Sea fireflies synchronize their sparkle to seek soulmates
(via sciencedaily.com) Original source In sea fireflies' underwater ballet, the males sway together in perfect, illuminated synchronization, basking in the glow of their secreted iridescent mucus.
Published Rocky planets can form in extreme environments
(via sciencedaily.com) Original source Astronomers have provided the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy. These results suggest that the conditions for terrestrial planet formation can occur in a possible broader range of environments than previously thought.
Published Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables
(via sciencedaily.com) Original source Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound. And periodical cicadas -- the insects that emerge by the billions every 13 or 17 years and make a racket with their mating calls -- are loud enough to be detected. A new study shows how fiber optic sensing could open new pathways for charting populations of these famously ephemeral bugs.
Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com) Original source Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published Unknown animals were leaving bird-like footprints in Late Triassic Southern Africa
(via sciencedaily.com) Original source Ancient animals were walking around on bird-like feet over 210 million years ago, according to a new study.
Published An astronomical waltz reveals a sextuplet of planets
(via sciencedaily.com) Original source Astronomers have found a key new system of six transiting planets orbiting a bright star in a harmonic rhythm. This rare property enabled the team to determine the planetary orbits which initially appeared as an unsolvable riddle.
Published New astrophysics model sheds light on additional source of long gamma-ray bursts
(via sciencedaily.com) Original source Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- gamma-ray bursts, or GRBs. The new unified model confirms that some long-lasting GRBs are created in the aftermath of cosmic mergers that spawn an infant black hole surrounded by a giant disk of natal material.
Published How do you make a robot smarter? Program it to know what it doesn't know
(via sciencedaily.com) Original source Engineers have come up with a new way to teach robots to know when they don't know. The technique involves quantifying the fuzziness of human language and using that measurement to tell robots when to ask for further directions. Telling a robot to pick up a bowl from a table with only one bowl is fairly clear. But telling a robot to pick up a bowl when there are five bowls on the table generates a much higher degree of uncertainty -- and triggers the robot to ask for clarification.
Published Heart over head? Stages of the heart's cycle affect neural responses
(via sciencedaily.com) Original source Optimal windows exist for action and perception during the 0.8 seconds of a heartbeat, according to new research. The sequence of contraction and relaxation is linked to changes in the motor system and its ability to respond to stimulation, and this could have implications for treatments for depression and stroke that excite nerve cells.
Published How shifting climates may have shaped early elephants' trunks
(via sciencedaily.com) Original source Researchers have provided new insights into how ancestral elephants developed their dextrous trunks. A study of the evolution of longirostrine gomphotheres, an ancestor of the modern day elephant, suggests moving into open-land grazing helped develop their coiling and grasping trunks.
Published Researchers engineer a material that can perform different tasks depending on temperature
(via sciencedaily.com) Original source Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment.
Published Defending your voice against deepfakes
(via sciencedaily.com) Original source Computer scientists have developed AntiFake, a tool to protect voice recordings from unauthorized speech synthesis.
