Published How a horse whisperer can help engineers build better robots



New research shows us that age-old interactions between people and their horses can teach us something about building robots designed to improve our lives.
Published Jellyfish-like robots could one day clean up the world's oceans



Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
Published Massive iceberg discharges during the last ice age had no impact on nearby Greenland, raising new questions about climate dynamics



New findings suggest that Heinrich Events had no discernible impact on temperatures in Greenland, which could have repercussions for scientists' understanding of past climate dynamics.
Published Puerto Rico tsunami deposit could have come from pre-Columbian megathrust earthquake



Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to new research.
Published ChatGPT is still no match for humans when it comes to accounting



ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical processes required for the latter type.
Published Two qudits fully entangled



Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.
Published African penguins: Climate refugees from a distant past?



Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.
Published A once-stable glacier in Greenland is now rapidly disappearing



As climate change causes ocean temperatures to rise, one of Greenland's previously most stable glaciers is now retreating at an unprecedented rate, according to a new study.
Published X-ray analysis sheds new light on prehistoric predator's last meal



We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.
Published The diversity of present tree species is shaped by climate change in the last 21,000 years



A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.
Published Nullarbor rocks reveal Australia's transformation from lush to dust



Researchers have discovered how long ago the Australian Nullarbor plain dried out, with a new approach shedding light on how ancient climate change altered some of the driest regions of our planet.
Published Team designs four-legged robotic system that can walk a balance beam



Researchers have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam -- a feat that is likely the first of its kind.
Published A neuromorphic visual sensor can recognize moving objects and predict their path



The new smart sensor uses embedded information to detect motion in a single video frame.
Published Multi-compartment membranes for multicellular robots: Everybody needs some body



We typically think of robots as metal objects, filled with motors and circuits. But the field of molecular robotics is starting to change that. Like the formation of complex living organisms, molecular robots derive their form and functionality from assembled molecules stored in a single unit, i.e., a body. Yet manufacturing this body at the microscopic level is an engineering nightmare. Now, a team has created a simple workaround.
Published Professor unearths the ancient fossil plant history of Burnaby Mountain



New research led by a paleobotanist provides clues about what plants existed in the Burnaby Mountain area (British Columbia, Canada) 40 million years ago during the late Eocene, when the climate was much warmer than it is today.
Published Research in Japan shows the way toward tactile and proximity sensing in large soft robots



To make human-robot interactions safer and more fruitful, robots should be capable of sensing their environment. In a recent study, researchers developed a novel robotic link with tactile and proximity sensing capabilities. Additionally, they created a simulation and learning framework that can be employed to train the robotic link to sense its environment. Their findings will pave the way to a future where humans and robots can operate harmoniously in close proximity.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball



Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions



Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Table tennis brain teaser: Playing against robots makes our brains work harder



Brain scans taken during table tennis reveal differences in how we respond to human versus machine opponents.
Published Kids judge Alexa smarter than Roomba, but say both deserve kindness



Most kids know it's wrong to yell or hit someone, but what if that someone is a robot named Alexa? A new study asked kids how smart and sensitive they thought the virtual assistant was compared to a robotic vacuum. Four- to eleven-year-olds rated Alexa as more intelligent than the Roomba but felt neither deserve to be yelled at or otherwise harmed.
