Jellyfish-like robots could one day clean up the world's oceans      (via sciencedaily.com)     Original source 

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.

ChatGPT is still no match for humans when it comes to accounting      (via sciencedaily.com)     Original source 

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.

Grambank shows the diversity of the world's languages      (via sciencedaily.com)     Original source 

What shapes the structure of languages? In a new study, an international team of researchers reports that grammatical structure is highly flexible across languages, shaped by common ancestry, constraints on cognition and usage, and language contact. The study used the Grambank database, which contains data on grammatical structures in over 2400 languages.

Multi-compartment membranes for multicellular robots: Everybody needs some body      (via sciencedaily.com)     Original source 

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.

Ancient DNA reveals the multiethnic structure of Mongolia's first nomadic empire      (via sciencedaily.com)     Original source 

The Xiongnu, contemporaries of Rome and Egypt, built their nomadic empire on the Mongolian steppe 2,000 years ago, emerging as Imperial China's greatest rival and even inspiring the construction of China's Great Wall. In a new study, researchers find that the Xiongnu were a multiethnic empire, with high genetic diversity found across the empire and even within individual extended elite families. At the fringes of the empire, women held the highest positions of power, and the highest genetic diversity was found among low-status male servants, giving clues to the process of empire building that gave rise to Asia's first nomadic imperial power.

Apes may have evolved upright stature for leaves, not fruit, in open woodland habitats      (via sciencedaily.com)     Original source 

Anthropologists have long thought that our ape ancestors evolved an upright torso in order to pick fruit in forests, but new research from the University of Michigan suggests a life in open woodlands and a diet that included leaves drove apes' upright stature.

Research in Japan shows the way toward tactile and proximity sensing in large soft robots      (via sciencedaily.com)     Original source 

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.

Kids judge Alexa smarter than Roomba, but say both deserve kindness      (via sciencedaily.com)     Original source 

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.
