Published Fiber optic cables detect and characterize earthquakes



The same fiber optic networks that provide internet can simultaneously act as earthquake sensors, as demonstrated in a new study.
Published Dune patterns reveal environmental change on Earth and other planets



Researchers have analyzed the shifting patterns of entire dune fields on Earth and Mars, as seen from orbit, and found they are a direct signature of recent environmental change. This new tool can be applied anywhere with dunes, such as Mars, Titan, and Venus.
Published Earth's most ancient impact craters are disappearing



Earth's oldest craters could give scientists critical information about the structure of the early Earth and the composition of bodies in the solar system as well as help to interpret crater records on other planets. But geologists can't find them, and they might never be able to, according to a new study.
Published Thermal imaging innovation allows AI to see through pitch darkness like broad daylight


Engineers have developed HADAR, or heat-assisted detection and ranging.
Published Sun 'umbrella' tethered to asteroid might help mitigate climate change



Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach -- a solar shield to reduce the amount of sunlight hitting Earth, combined with a tethered, captured asteroid as a counterweight. Engineering studies using this approach could start now to create a workable design that could mitigate climate change within decades.
Published GPT-3 can reason about as well as a college student, psychologists report


The artificial intelligence language model GPT-3 performed as well as college students in solving certain logic problems like those that appear on standardized tests. The researchers who conducted the experiment write that the results prompt the question of whether the technology is mimicking human reasoning or using a new type of cognitive process. Solving that question would require access to the software that underpins GPT-3 and other AI software.
Published 3D display could soon bring touch to the digital world


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 Reinforcement learning allows underwater robots to locate and track objects underwater


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 This 3D printed gripper doesn't need electronics to function


This soft robotic gripper is not only 3D printed in one print, it also doesn't need any electronics to work.
Published Researchers develop low-cost sensor to enhance robots' sense of touch


Researchers have developed an L3 F-TOUCH sensor to enhance tactile capabilities in robots, allowing it to 'feel' objects and adjust its grip accordingly.
Published A simpler method for learning to control a robot


A new machine-learning technique can efficiently learn to control a robot, leading to better performance with fewer data.
Published Robotic hand rotates objects using touch, not vision


Inspired by the effortless way humans handle objects without seeing them, engineers have developed a new approach that enables a robotic hand to rotate objects solely through touch, without relying on vision.
Published Missing island explains how endemic species on the Miyako Islands emerged



Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.
Published What can central Utah's earthquake 'swarms' reveal about the West's seismicity?



Much of central Utah's seismic activity comes in groups of small earthquakes. A study by seismologists examines 2,300 quakes occurring 40 'swarms' dating back to 1981, opening a window into Earth's crust in a geothermally active area.
Published Robot preachers get less respect, fewer donations


As artificial intelligence expands across more professions, robot preachers and AI programs offer new means of sharing religious beliefs, but they may undermine credibility and reduce donations for religious groups that rely on them.
Published Future AI algorithms have potential to learn like humans


Memories can be as tricky to hold onto for machines as they can be for humans. To help understand why artificial agents develop holes in their own cognitive processes, electrical engineers have analyzed how much a process called 'continual learning' impacts their overall performance.
Published Allowing robots to explore on their own


Scientists have developed a suite of robotic systems and planners enabling robots to explore more quickly, probe the darkest corners of unknown environments, and create more accurate and detailed maps. The systems allow robots to do all this autonomously, finding their way and creating a map without human intervention.
Published A faster way to teach a robot


A new technique enables a human to efficiently fine-tune a robot that failed to complete a desired task with very little effort on the part of the human. Their system uses algorithms, counterfactual explanations, and feedback from the user to generate synthetic data it uses to quickly fine-tune the robot.
Published Bot inspired by baby turtles can swim under the sand


This robot can swim under the sand and dig itself out too, thanks to two front limbs that mimic the oversized flippers of turtle hatchlings. It's the only robot that is able to travel in sand at a depth of 5 inches. It can also travel at a speed of 1.2 millimeters per second--roughly 4 meters, or 13 feet, per hour. This may seem slow but is comparable to other subterranean animals like worms and clams.
Published Robotics: New skin-like sensors fit almost everywhere


Researchers have developed an automatic process for making soft sensors. These universal measurement cells can be attached to almost any kind of object. Applications are envisioned especially in robotics and prosthetics.
