Combustion powers bug-sized robots to leap, lift and race      (via sciencedaily.com) 

Researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors.

Buried ancient Roman glass formed substance with modern applications      (via sciencedaily.com)     Original source 

Researchers discover how molecules in ancient glass rearrange and recombine with minerals over centuries to form a patina of photonic crystals -- ordered arrangements of atoms that filter and reflect light in very specific ways -- an analog of materials used in communications, lasers and solar cells.

Making AI smarter with an artificial, multisensory integrated neuron      (via sciencedaily.com)     Original source 

The feel of a cat's fur can reveal some information, but seeing the feline provides critical details: is it a housecat or a lion? While the sound of fire crackling may be ambiguous, its scent confirms the burning wood. Our senses synergize to give a comprehensive understanding, particularly when individual signals are subtle. The collective sum of biological inputs can be greater than their individual contributions. Robots tend to follow more straightforward addition, but researchers have now harnessed the biological concept for application in artificial intelligence (AI) to develop the first artificial, multisensory integrated neuron.

How just one set of animal tracks can provide a wealth of information      (via sciencedaily.com)     Original source 

Rock faces in Namibia are decorated with hundreds of stone-age images not only of animals and human footprints, but also of animal tracks. These have been largely neglected to date as researchers lacked the knowledge required to interpret them. Archaeologists have now worked together with animal tracking experts to investigate the engraved animal tracks on six rock faces in more detail, and were able to determine detailed information on the species, age, sex, limbs, side of the body, trackway and relative direction of the tracks.

Evolution wired human brains to act like supercomputers      (via sciencedaily.com) 

Scientists have confirmed that human brains are naturally wired to perform advanced calculations, much like a high-powered computer, to make sense of the world through a process known as Bayesian inference.

Battery-free robots use origami to change shape in mid-air      (via sciencedaily.com) 

Researchers have developed small robotic devices that can change how they move through the air by 'snapping' into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air.

Shipboard cannon found off the Swedish coast may be the oldest in Europe      (via sciencedaily.com)     Original source 

Maritime archaeologists have studied what might be Europe's oldest shipboard cannon. The cannon was found in the sea off Marstrand on the Swedish west coast and dates back to the 14th century. The findings from the interdisciplinary study contribute new knowledge about the early development of artillery on land and at sea, but also bears witness to a troubled period for seafarers as well as coastal populations.

'Brainless' robot can navigate complex obstacles      (via sciencedaily.com) 

Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a 'brainless' soft robot that can navigate more complex and dynamic environments.

What do neurons, fireflies and dancing the Nutbush have in common?      (via sciencedaily.com) 

Synchronicity is all around us, but it is poorly understood. Computer scientists have now developed new tools to understand how human and natural networks fall in and out of sync.

St Helena's 'liberated' Africans came from West Central Africa between northern Angola and Gabon      (via sciencedaily.com)     Original source 

Between 1840 and 1867, thousands of enslaved Africans who had been 'liberated' from slave ships intercepted by the British Royal Navy were taken to the South Atlantic island of St Helena. But little is written in history books or otherwise known about the lives of these individuals. Now, ancient DNA analyses offer the first direct evidence for the origins of St Helena's liberated Africans.

Paving the way for advanced quantum sensors      (via sciencedaily.com) 

Quantum physics has allowed for the creation of sensors far surpassing the precision of classical devices. Now, several new studies show that the precision of these quantum sensors can be significantly improved using entanglement produced by finite-range interactions. Researchers were able to demonstrate this enhancement using entangled ion-chains with up to 51 particles.

Wastewater pipe dig reveals 'fossil treasure trove'      (via sciencedaily.com)     Original source 

A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.
