A proprioceptive mechanism to enable fish-like swimming in robots

Over the past few decades, roboticists have developed a variety of robots inspired by nature, humans and animals. To effectively mimic animals or humans, however, these robots should not only look like them; they should also move in similar ways.

A new piece of the quantum computing puzzle

Research from the McKelvey School of Engineering at Washington University in St. Louis has found a missing piece in the puzzle of optical quantum computing.

New type of metasurface allows unprecedented laser control

The ability to precisely control the various properties of laser light is critical to much of the technology that we use today, from commercial virtual reality (VR) headsets to microscopic imaging for biomedical research. Many of today's laser systems rely on separate, rotating components to control the wavelength, shape and power of a laser beam, making these devices bulky and difficult to maintain.

In Physics of Fluids, researchers explain how turbulence in the air can create surprising and counterintuitive behavior of exhaled droplets, potentially laden with virus.

Turning plastic into foam to combat pollution

Biodegradable plastics are supposed to be good for the environment. But because they are specifically made to degrade quickly, they cannot be recycled.

Identifying a topological fingerprint

A FLEET theoretical study out this week has found a 'smoking gun' in the long search for the topological magnetic monopole referred to as the Berry curvature.

A new type of quasiparticle

Russian scientists have experimentally proved the existence of a new type of quasiparticle—previously unknown excitations of coupled pairs of photons in qubit chains. This discovery could be a step towards disorder-robust quantum metamaterials. The study was published in Physical Review B.

Hunting dark energy with gravity resonance spectroscopy

Dark Energy is widely believed to be the driving force behind the universe's accelerating expansion, and several theories have now been proposed to explain its elusive nature. However, these theories predict that its influence on quantum scales must be vanishingly small, and experiments so far have not been accurate enough to either verify or discredit them. In new research published in EPJ ST, a team led by Hartmut Abele at TU Wien in Austria demonstrates a robust experimental technique for studying one such theory, using ultra-cold neutrons. Named "Gravity Resonance Spectroscopy" (GRS), their approach could bring researchers a step closer to understanding one of the greatest mysteries in cosmology.

Astronomy and Space news

Massive quiescent galaxy found in a distant protocluster

Using the Keck I telescope, Japanese astronomers have identified a massive quiescent galaxy in a distant galaxy protocluster known as SSA22. The galaxy, designated ADF22-QG1, turns out to be the most distant quiescent galaxy in a protocluster to date. The finding is reported in a paper published June 21 on the arXiv pre-print repository.

Astrophysicists detect first black hole-neutron star mergers

A long time ago, in two galaxies about 900 million light-years away, two black holes each gobbled up their neutron star companions, triggering gravitational waves that finally hit Earth in January 2020.

Clearest images emerge of galaxies headed for collision on intergalactic 'highway'

An international group of astronomers has created images with never-before-seen detail of a galaxy cluster with a black hole at its center, traveling at high speed along an intergalactic "road of matter." The findings also support existing theories of the origins and evolution of the universe.

Glauconitic-like clay found on Mars suggests the planet once had habitable conditions

A team of researchers from Spain, France and the U.S. has found evidence of a glauconitic-like clay on Mars that suggests the planet once had habitable conditions. In their paper published in the journal Nature Astronomy, the group describes their study of clay minerals extracted from Gale Crater by Curiosity rover back in 2016 and what they found.

Bend it like Einstein: Astronomers turn galaxies into magnifiers

Astronomers have turned a cluster of galaxies into a gargantuan magnifying lens, using it to study another galaxy, 10.7 billion light years away, in unprecedented detail.

A model to predict how much humans and robots can be trusted with completing specific tasks

Researchers at University of Michigan have recently developed a bi-directional model that can predict how much both humans and robotic agents can be trusted in situations that involve human-robot collaboration. This model, presented in a paper published in IEEE Robotics and Automation Letters, could help to allocate tasks to different agents more reliably and efficiently.

How to build a better wind farm

Location, location, location—when it comes to the placement of wind turbines, the old real estate adage applies, according to new research published in Proceedings of the National Academy of Sciences by Carnegie's Enrico Antonini and Ken Caldeira.

Kiriform structures harness buckling for stable, deployable structures

Deployable structures—objects that transition from a compact state to an expanded one—are used everywhere from backyards to Mars. But as anyone who has ever struggled to open an uncooperative folding chair knows, transforming two-dimensional forms into three-dimensional structures is sometimes a challenge.

Steering wind turbines creates greater energy potential

As wind passes through a turbine, it creates a wake that decreases the downstream average wind velocity. The faster the spin of the turbine blades relative to the wind speed, the greater the impact on the downstream wake profile.

Conductive seams, when strategically placed in clothing, can accurately track body motion: study

When positioned strategically, garment seams sewn with conductive yarn can be used to accurately track body motion, according to computer scientists at the University of Bath in the UK. Best of all, these charged seams are able to respond to subtle movements that aren't picked up by popular fitness trackers, such as watches and wristbands.

Team proposes a data-driven approach for a more sustainable utility rate structure

Many drivers use tollways to get from point A to point B because they are a faster and more convenient option. The fees associated with these roadways are higher during peak traffic hours of the day, such as during the commute to and from work. With this structure, drivers who are not adding to the heavy flow of traffic do not have to pay higher toll prices. However, those who utilize the toll road during more congested hours pay a premium to use the faster, more convenient highways.
