Published Why you shouldn't declaw tigers or other big cats



Researchers looked at the effects of declawing on larger cat species and found that declawing disproportionately impacts their muscular capabilities as compared to their smaller brethren.
Published Scientists create novel approach to control energy waves in 4D


Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.
Published That's funny -- but AI models don't get the joke


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 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 Way cool: 'freeze ray' technology


An unusual discovery is now being developed as an on-demand cooling solution for high-flying military electronics.
Published Researchers successfully train a machine learning model in outer space for the first time



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 Scientists vacuum animal DNA from air in a Danish forest



Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.
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 Fast electrical signals mapped in plants with new bioelectronic technology



What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress.
Published Aphids make tropical milkweed less inviting to monarch butterflies



When oleander aphids infested tropical milkweed, monarch butterflies laid fewer eggs on the plant, and the caterpillars developing on those plants were slower to mature.
Published Climate change threatens 771 endangered plant and lichen species



All plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change but there are few plans in place to address this threat directly, according to new research.
Published Global wildlife trade risks altering evolutionary history and ecosystem function, study suggests



Some of the world's most distinct and ancient animal species, which play crucial roles in our planet's ecosystems, are exploited for the wildlife trade across large parts of the world, according to new research.
Published Genetic study reveals that a captive-bred population could save endangered crocodile from extinction



Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.
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 Arctic terns may navigate climate dangers



Arctic terns -- which fly on the longest migrations of any animal on Earth -- may be able to navigate the dangers posed by climate change, new research suggests.
Published Discovery of key genetic sequence essential for plant reproduction



Researchers have identified a genetic sequence that is essential for plant reproduction. As this region is found in all plant species, it is expected to contribute to future crossbreeding initiatives and help solve the important problem of seed formation defects.
Published Soil microbes help plants cope with drought, but not how scientists thought



In a multi-generation experiment, researchers found microbes helped plants cope with drought, but not in response to plants' cries for help. Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.
Published Forgotten tropical plants rediscovered after 100-plus years with the help of community science



Deep in the tropical Andes, a genus called Nasa harbored elusive and forgotten plant species. Through the collaborative efforts of botanists and citizen scientists on iNaturalist, these plants have been rediscovered after decades, some even after more than a century.
