Published 319-million-year-old fish preserves the earliest fossilized brain of a backboned animal
(via sciencedaily.com) The CT-scanned skull of a 319-million-year-old fossilized fish, pulled from a coal mine in England more than a century ago, has revealed the oldest example of a well-preserved vertebrate brain.
Published Legged robots need more testing before real-world use
(via sciencedaily.com) When it comes to the 'evolution' of mobile robots, it may be a long time before legged robots are able to safely interact in the real world, according to a new study.
Published Autonomous steering system keeps human drivers engaged
(via sciencedaily.com) Researchers have developed an automated driving system based on the concept of 'collaborative steering', which aims to increase transportation safety, efficiency, and comfort by encouraging active interaction between autonomous vehicles and their human drivers.
Published New ancient 'marine crocodile' discovered on UK's Jurassic Coast -- and it's one of the oldest specimens of its type ever found
(via sciencedaily.com) A new study has uncovered a new thalattosuchian -- an ancient 'sister' of modern-day crocodiles' ancestors.
Published Will machine learning help us find extraterrestrial life?
(via sciencedaily.com) Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of interest.
Published A neuro-chip to manage brain disorders
(via sciencedaily.com) Researchers have combined low-power chip design, machine learning algorithms, and soft implantable electrodes to produce a neural interface that can identify and suppress symptoms of various neurological disorders.
Published A fairy-like robot flies by the power of wind and light
(via sciencedaily.com) The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?
Published Qubits on strong stimulants
(via sciencedaily.com) Original source In the global push for practical quantum networks and quantum computers, an international team of researchers has demonstrated a leap in preserving the quantum coherence of quantum dot spin qubits.
Published Quantum physicists make major nanoscopic advance
(via sciencedaily.com) Original source In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Published Scientists observe 'quasiparticles' in classical systems
(via sciencedaily.com) Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs -- a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems.
Published AI technology generates original proteins from scratch
(via sciencedaily.com) Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.
Published Versatile robo-dog runs through the sandy beach at 3 meters per second
(via sciencedaily.com) Meet the new addition to the robo-dog family, 'RaiBo', that can run along the sandy beach without losing balance and walk through grassy fields and back on the hard-floored tracking fields all on its own -- no further tinkering necessary.
Published Person-shaped robot can liquify and escape jail, all with the power of magnets
(via sciencedaily.com) Inspired by sea cucumbers, engineers have designed miniature robots that rapidly and reversibly shift between liquid and solid states. On top of being able to shape-shift, the robots are magnetic and can conduct electricity. The researchers put the robots through an obstacle course of mobility and shape-morphing tests.
Published New geosciences study shows Triassic fossils that reveal origins of living amphibians
(via sciencedaily.com) A team of paleontologists have discovered the first 'unmistakable' Triassic-era caecilian fossil -- the oldest-known caecilian fossils -- thus extending the record of this small, burrowing animal by roughly 35 million years. The find also fills a gap of at least 87 million years in the known historical fossil record of the amphibian-like creature.
Published A butterfly flaps its wings and scientists make jewelry
(via sciencedaily.com) In the 'butterfly effect,' an insect can flap its wings and create a microscopic change in initial conditions that leads to a hurricane halfway around the world. This chaos is seen everywhere, from weather to labor markets to brain dynamics. And now researchers explored how to turn the twisting, fractal structures behind the science into jewelry with 3D printing. The jewelry shapes are based on the Chua circuit, a simple electronic system that was the first physical, mathematical, and experimental proof of chaos.
Published Click beetle-inspired robots jump using elastic energy
(via sciencedaily.com) Researchers have made a significant leap forward in developing insect-sized jumping robots capable of performing tasks in the small spaces often found in mechanical, agricultural and search-and-rescue settings. A new study demonstrates a series of click beetle-sized robots small enough to fit into tight spaces, powerful enough to maneuver over obstacles and fast enough to match an insect's rapid escape time.
Published First computational reconstruction of a virus in its biological entirety
(via sciencedaily.com) A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.
Published Plague trackers: Researchers cover thousands of years in a quest to understand the elusive origins of the Black Death
(via sciencedaily.com) Seeking to better understand more about the origins and movement of bubonic plague, in ancient and contemporary times, researchers have completed a painstaking granular examination of hundreds of modern and ancient genome sequences, creating the largest analysis of its kind.
Published Mummified crocodiles provide insights into mummy-making over time
(via sciencedaily.com) Crocodiles were mummified in a unique way at the Egyptian site of Qubbat al-Hawa during the 5th Century BC, according to a new study.
Published Microelectronics give researchers a remote control for biological robots
(via sciencedaily.com) First, they walked. Then, they saw the light. Now, miniature biological robots have gained a new trick: remote control. The hybrid 'eBiobots' are the first to combine soft materials, living muscle and microelectronics, said researchers.
