Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes      (via sciencedaily.com)     Original source 

Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.

Archaeologists map hidden NT landscape where first Australians lived more than 60,000 years ago      (via sciencedaily.com)     Original source 

Scientists have used sub-surface imaging and aerial surveys to see through floodplains in the Red Lily Lagoon area of West Arnhem Land in Australia. These ground-breaking methods showed how this important landscape in the Northern Territory was altered as sea levels rose about 8,000 years ago.

AI could run a million microbial experiments per year      (via sciencedaily.com)     Original source 

Automation uncovers combinations of amino acids that feed two bacterial species and could tell us much more about the 90% of bacteria that humans have hardly studied. An artificial intelligence system enables robots to conduct autonomous scientific experiments -- as many as 10,000 per day -- potentially driving a drastic leap forward in the pace of discovery in areas from medicine to agriculture to environmental science.

Scientists recover an ancient woman's DNA from a 20,000-year-old pendant      (via sciencedaily.com)     Original source 

An international research team has for the first time successfully isolated ancient human DNA from a Paleolithic artefact: a pierced deer tooth discovered in Denisova Cave in southern Siberia. To preserve the integrity of the artefact, they developed a new, nondestructive method for isolating DNA from ancient bones and teeth. From the DNA retrieved they were able to reconstruct a precise genetic profile of the woman who used or wore the pendant, as well as of the deer from which the tooth was taken. Genetic dates obtained for the DNA from both the woman and the deer show that the pendant was made between 19,000 and 25,000 years ago. The tooth remains fully intact after analysis, providing testimony to a new era in ancient DNA research, in which it may become possible to directly identify the users of ornaments and tools produced in the deep past.

A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads      (via sciencedaily.com)     Original source 

It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.

Highly dexterous robot hand can operate in the dark -- just like us      (via sciencedaily.com)     Original source 

Researchers demonstrated a highly dexterous robot hand, one that combines an advanced sense of touch with motor learning algorithms in order to achieve a high level of dexterity. In addition, the hand worked without any external cameras -- it's immune to lighting, occlusion, or similar issues. Because the hand doesn't rely on vision to manipulate objects, it can do so in difficult lighting conditions that would confuse vision-based algorithms -- it even operates in the dark.

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.

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.
