Published Voiceless frog discovered in Tanzania
(via sciencedaily.com)
Original source 
Researchers discovered a new species of frog in Africa that has an unusual trait: it's completely silent. The Ukaguru spiny-throated reed frog does not croak, sing or ribbit. Found in Tanzania's Ukaguru Mountains for which it is named, Hyperolius ukaguruensis is among the few frogs around the world that do not vocalize to other frogs.
Published Entangled atoms cross quantum network from one lab to another
(via sciencedaily.com) 
Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.
Published Deer browsing is just one of many factors shaping North American forests
(via sciencedaily.com) 
In a new study, a research team discovered evidence that browsing by white-tailed deer had relatively little long-term impact on two tree species in a northern forest.
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 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 UK's Overseas Territories at ongoing risk from wide range of invasive species
(via sciencedaily.com) 
A new study has for the first time predicted which invasive species could pose a future threat to the UK's ecologically unique Overseas Territories.
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 New species of microalgae discovered
(via sciencedaily.com) 
A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers discovered Medakamo hakoo, whose DNA sequence didn't match any on record. This new species is the smallest known freshwater green algae, with inherent qualities which enable it to be cultured stably at high density, meaning it could be effectively used to produce useful products for food and industry.
Published Ancestral variation guides future environmental adaptations
(via sciencedaily.com) 
The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity. New research shows that early plasticity can influence the ability to subsequently evolve genetic adaptations to conquer new habitats.
Published Rapid plant evolution may make coastal regions more susceptible to flooding and sea level rise, study shows
(via sciencedaily.com) 
Evolution has occurred more rapidly than previously thought in the Chesapeake Bay wetlands, which may decrease the chance that coastal marshes can withstand future sea level rise, researchers at the University of Notre Dame and collaborators demonstrated in a recent publication in Science.
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 How salmon feed flowers and flourishing ecosystems
(via sciencedaily.com) 
Nutrients from salmon carcasses can substantively alter the growth and reproduction of plant species in the surrounding habitat, and even cause some flowers to grow bigger and more plentiful, researchers have found.
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 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.
