How microscopic scallops wander

All microscopic objects, from enzymes to paint particles, are jittering constantly, bombarded by solvent particles: this is called Brownian motion. How does this motion change when the object is flexible instead of rigid? Ruben Verweij, Pepijn Moerman, and colleagues published the first measurements in Physical Review Research.

Experimental optimal verification of entangled states using local measurements

Quantum information is a field where the information is encoded into quantum states. Taking advantage of the "quantumness" of these states, scientists can perform more efficient computations and more secure cryptography compared to their classical counterparts.

In vivo imaging of the human cornea at high speed and high resolution

If the eyes are the mirror of the soul, then thanks to the translucent corneas, we can look deep into that soul. And thanks to the work of scientists from the Institute of Physical Chemistry of the Polish Academy of Sciences, we can look into the depths of the cornea itself. And that without touching it. All thanks to the introduction of an innovative method of holographic optical tomography.

A photonic amorphous topological insulator

The current understanding of topological insulators and their classical wave analogs, such as photonic topological insulators, is mainly based on topological band theory. Contrary to this, Scientists in China and Singapore experimentally showed photonic topological insulators based on glass-like amorphous phases, for which the bandstructure is ill-defined. The persistence of topological protection is also found to be closely related to the glass-to-liquid transition. This interplay between topology and amorphousness paves the way for new classes of non-crystalline topological photonic bandgap materials.

Astronomy and Space news

Two new high-redshift red quasars discovered

Using the Subaru Telescope, astronomers have identified two new dust-reddened (red) quasars at high redshifts. The finding, detailed in a paper published July 16 on the arXiv pre-print server, could improve the understanding of these rare but interesting objects.

Researchers offer unprecedented look into 'central engine' powering a solar flare

In a study published in Nature Astronomy, an international team of researchers has presented a new, detailed look inside the "central engine" of a large solar flare accompanied by a powerful eruption first captured on Sept. 10, 2017 by the Owens Valley Solar Array (EOVSA)—a solar radio telescope facility operated by New Jersey Institute of Technology's (NJIT) Center for Solar-Terrestrial Research (CSTR).

Testing Chernobyl fungi as a radiation shield for astronauts

A team of researchers from the University of North Carolina at Charlotte and Stanford University has tested the viability of using a type of fungus found growing in some of the destroyed nuclear reactors at the former Chernobyl nuclear power plant site to shield astronauts from radiation. They have written a paper describing their work and have uploaded it to the bioRxiv preprint site.

The moons of Uranus are fascinating enough on their own that we should send a flagship mission out there

What's the most interesting fact you know about Uranus? The fact that its rotational axis is completely out of line with every other planet in the solar system? Or that Uranus' magnetosphere is asymmetrical, notably tilted relative to its rotational axis, and significantly offset from the center of the planet? Or that its moons are all named after characters from Shakespeare or Alexander Pope?

Launch of the world's first soft X-ray satellite with 'Lobster-Eye' imaging technology

The 'Lobster-Eye X-ray Satellite' was successfully launched on July 25 into orbit from the Taiyuan Launch Center, with the first signal received, riding the Long March 4B lift rocket. The Lobster-Eye X-ray Satellite project is co-led by Nanjing University (NJU), the Laboratory for Space Research (LSR) of The University of Hong Kong (HKU), the 508 Institute of the Fifth Academy of China Aerospace Science and Technology Corporation (CASC), and Shanghai ASES Spaceflight Technology Co.Ltd. also under the 805 Institute of the Eighth Academy of CASC. It was successfully developed through five years of joint effort by the above outstanding teams. The satellite is equipped with an internally developed 'Lobster-Eye' focused X-ray detector and a small high-precision payload platform. During the satellite's long-term orbit operations, it will verify the ultra-large X-ray field-of-view within the X-ray energy regime and complete several important space X-ray detection experiments. This includes carrying out dark matter signal detection research within the X-ray energy regime in an earth orbit environment.

Mars 2020 mission to be guided by USGS astrogeology maps

When NASA's Perseverance rover lands on Mars next year, it will be equipped with some of the most precise maps of Mars ever created, courtesy of the USGS Astrogeology Science Center. Not only are the new maps essential for a safe landing on Mars, but they also serve as the foundation upon which the science activities planned for the Mars mission will be built.

Laser inversion enables multi-materials 3-D printing

Additive manufacturing—or 3-D printing—uses digital manufacturing processes to fabricate components that are light, strong, and require no special tooling to produce. Over the past decade, the field has experienced staggering growth, at a rate of more than 20% per year, printing pieces that range from aircraft components and car parts to medical and dental implants out of metals and engineering polymers. One of the most widely used manufacturing processes, selective laser sintering (SLS), prints parts out of micron-scale material powders using a laser: the laser heats the particles to the point where they fuse together to form a solid mass.
