Published Engineers are on a failure-finding mission



Engineers developed a technique to quickly identify a range of potential failures in a system before they are deployed in the real world.
Published How human faces can teach androids to smile



A research team used 125 physical markers to understand the detailed mechanics of 44 different human facial motions. The aim was to better understand how to convey emotions with artificial faces. Beyond helping with the design of robots and androids, this research can also benefit computer graphics, facial recognition, and medical diagnoses.
Published Palaeo-CSI: Mosasaurs were picky eaters



Mosasaurs, those large marine reptiles from the long-gone Cretaceous world, were quite picky in their choice of diet. Researchers came to this conclusion after studying the wear marks on mosasaur teeth.
Published Head lice evolution mirrors human migration and colonization in the Americas



A new analysis of lice genetic diversity suggests that lice came to the Americas twice -- once during the first wave of human migration across the Bering Strait, and again during European colonization.
Published Machine learning gives users 'superhuman' ability to open and control tools in virtual reality



Researchers have developed a virtual reality application where a range of 3D modelling tools can be opened and controlled using just the movement of a user's hand.
Published French love letters confiscated by Britain finally read after 265 years



Over 100 letters sent to French sailors by their fianc es, wives, parents and siblings -- but never delivered -- have been opened and studied for the first time since they were written in 1757-8.
Published Neuromorphic computing will be great... if hardware can handle the workload



Scientists believe they may have discovered a way to rework the hardware of AI. By mimicking the synapses of the human brain.
Published 450-million-year-old organism finds new life in Softbotics



Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Long-distance weaponry identified at the 31,000-year-old archaeological site of Maisières-Canal



The hunter-gatherers who settled on the banks of the Haine, a river in southern Belgium, 31,000 years ago were already using spearthrowers to hunt their game. The material found at the archaeological site of Maisières-Canal permits establishing the use of this hunting technique 10,000 years earlier than the oldest currently known preserved spearthrowers. This discovery is prompting archaeologists to reconsider the age of this important technological innovation.
Published AI should be better understood and managed -- new research warns



Artificial Intelligence (AI) and algorithms can and are being used to radicalize, polarize, and spread racism and political instability, says an academic. An expert argues that AI and algorithms are not just tools deployed by national security agencies to prevent malicious activity online, but can be contributors to polarization, radicalism and political violence -- posing a threat to national security.
Published Hebrew prayer book fills gap in Italian earthquake history



The chance discovery of a note written in a 15th century Hebrew prayer book fills an important gap in the historical Italian earthquake record, offering a brief glimpse of a previously unknown earthquake affecting the Marche region in the central Apennines.
Published Giant dinosaur carcasses might have been important food sources for Jurassic predators



Carnivorous dinosaurs might have evolved to take advantage of giant carcasses, according to a new study.
Published Where is a sea star's head? Maybe just about everywhere



A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.
Published Nanowire 'brain' network learns and remembers 'on the fly'



Like a collection of 'Pick Up Sticks', this neural network has passed a critical step for developing machine intelligence. For the first time, a physical neural network has successfully been shown to learn and remember 'on the fly', in a way inspired by and similar to how the brain's neurons work. The result opens a pathway for developing efficient and low-energy machine intelligence for more complex, real-world learning and memory tasks.
Published The brain may learn about the world the same way some computational models do



New studies support the idea that the brain uses a process similar to a machine-learning approach known as 'self-supervised learning.' This type of machine learning allows computational models to learn about visual scenes based solely on the similarities and differences between them, with no labels or other information.
Published Study uncovers hundred-year lifespans for three freshwater fish species in the Arizona desert



New study finds some of the oldest animals in the world living in a place you wouldn't expect: fishes in the Arizona desert.
Published New species of mosasaur named for Norse sea serpent



Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With 'transitional' traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found.
Published Cold War spy satellite imagery reveals Ancient Roman forts



A new study analyzing declassified Cold War satellite imagery reveals 396 previously undocumented Roman forts and reports that these forts were constructed from east to west, spanning from what is now western Syria to northwestern Iraq. The analysis refutes Father Antoine Poidebard's claim that the forts were located along a north-south axis.
Published Robot stand-in mimics movements in VR



Researchers have developed a souped-up telepresence robot that responds automatically and in real-time to a remote user's movements and gestures made in virtual reality.
Published Engineers develop breakthrough 'robot skin'



Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.
