Published Artificial muscle device produces force 34 times its weight
(via sciencedaily.com)
Original source 
Scientists developed a soft fluidic switch using an ionic polymer artificial muscle that runs with ultra-low power to lift objects 34 times greater than its weight. Its light weight and small size make it applicable to various industrial fields such as soft electronics, smart textiles, and biomedical devices by controlling fluid flow with high precision, even in narrow spaces.
Published Ancient cities provide key datasets for urban planning, policy and predictions in the Anthropocene
(via sciencedaily.com)
Original source 
A new study shows how state-of-the-art methods and perspectives from archaeology, history, and palaeoecology are shedding new light on 5,500 years of urban life.
Published Prehistoric person with Turner syndrome identified from ancient DNA
(via sciencedaily.com)
Original source 
Researchers have developed a new technique to measure the number of chromosomes in ancient genomes more precisely, using it to identify the first prehistoric person with mosaic Turner syndrome (characterized by one X chromosome instead of two [XX]), who lived about 2500 years ago.
Published Artificial intelligence helps unlock advances in wireless communications
(via sciencedaily.com)
Original source 
A new wave of communication technology is quickly approaching and researchers are now investigating ways to configure next-generation mobile networks.
Published New research sheds light on an old fossil solving an evolutionary mystery
(via sciencedaily.com)
Original source 
Picrodontids -- an extinct family of placental mammals that lived several million years after the extinction of the dinosaurs -- are not primates as previously believed.
Published Discovery of immense fortifications dating back 4,000 years in north-western Arabia
(via sciencedaily.com)
Original source 
The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis -- one of the longest known going back to this period -- was just revealed by a team of scientists. This new walled oasis is, along with that of Tayma, one of the two largest in Saudi Arabia.
Published Study on lamprey embryos sheds light on the evolutionary origin of vertebrate head
(via sciencedaily.com)
Original source 
Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science.
Published A beating biorobotic heart aims to better simulate valves
(via sciencedaily.com)
Original source 
Combining a biological heart and a silicone robotic pump, researchers created a biorobotic heart that beats like a real one, with a focus on a valve on the left side of the heart. The heart valve simulator can mimic the structure, function, and motion of a healthy or diseased heart, allowing surgeons and researchers to demonstrate various interventions while collecting real-time data.
Published The extinction of the giant ape: Long-standing mystery solved
(via sciencedaily.com)
Original source 
The largest ever primate Gigantopithecus blacki went extinct when other Asian great apes were thriving, and its demise has long been a mystery. A massive regional study of 22 caves in southern China explores a species on the brink of extinction between 295,000 and 215,000 years ago. As the environment became more seasonal, forest plant communities changed Primates such as orangutans adapted their eating habits and behaviors in response but G. blacki showed signs of stress, struggled to adapt and their numbers dwindled.
Published Towards more accurate 3D object detection for robots and self-driving cars
(via sciencedaily.com)
Original source 
Robots and autonomous vehicles can use 3D point clouds from LiDAR sensors and camera images to perform 3D object detection. However, current techniques that combine both types of data struggle to accurately detect small objects. Now, researchers have developed DPPFA Net, an innovative network that overcomes challenges related to occlusion and noise introduced by adverse weather. Their findings will pave the way for more perceptive and capable autonomous systems.
Published New soft robots roll like tires, spin like tops and orbit like moons
(via sciencedaily.com)
Original source 
Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.
Published Fastest swimming insect could inspire uncrewed boat designs
(via sciencedaily.com)
Original source 
Whirligig beetles, the world's fastest-swimming insect, achieve surprising speeds by employing a strategy shared by fast-swimming marine mammals and waterfowl, according to a new study that rewrites previous explanations of the physics involved.
Published Cult mentality: Monumental discovery in Italy
(via sciencedaily.com)
Original source 
Researchers have discovered an ancient Roman temple that adds significant insights into the social change from pagan gods to Christianity within the Roman Empire.
Published Soft robotic, wearable device improves walking for individual with Parkinson's disease
(via sciencedaily.com)
Original source 
Researchers have used a soft, wearable robot to help a person living with Parkinson's walk without freezing. The robotic garment, worn around the hips and thighs, gives a gentle push to the hips as the leg swings, helping the patient achieve a longer stride. The device completely eliminated the participant's freezing while walking indoors, allowing them to walk faster and further than they could without the garment's help.
Published Early primates likely lived in pairs
(via sciencedaily.com)
Original source 
Primate social organization is more flexible than previously assumed. According to a new study, the first primates probably lived in pairs, while only around 15 percent of individuals were solitary.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought
(via sciencedaily.com)
Original source 
Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published First high mountain settlers at the start of the Neolithic already engaged in other livestock activities apart from transhumance
(via sciencedaily.com)
Original source 
An archaeological find in the Huescan Pyrenees allowed researchers to identify for the first time livestock management strategies and feeding practices which demonstrate how the first high mountain societies, at the start of the Neolithic period, were already carrying out complex livestock and farming activities, instead of being limited to the transhumance of sheep and goats.
Published Could an electric nudge to the head help your doctor operate a surgical robot?
(via sciencedaily.com)
Original source 
People who received gentle electric currents on the back of their heads learned to maneuver a robotic surgery tool in virtual reality and then in a real setting much more easily than people who didn't receive those nudges, a new study shows.
Published Rise of archery in Andes Mountains dated to 5,000 years ago -- earlier than previous research
(via sciencedaily.com)
Original source 
Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago. The new research from UC Davis indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.
Published AI's memory-forming mechanism found to be strikingly similar to that of the brain
(via sciencedaily.com)
Original source 
An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
