Bubble dynamics reveal how to empty bottles faster

Bottle emptying is a phenomenon most of us have observed while pouring a beverage. Researchers from the Indian Institute of Technology Roorkee discovered how to make bottles empty faster, which has wide-ranging implications for many areas beyond the beverage industry.

Simulations show extreme opinions can lead to polarized groups

In recent years, chaos theory and other forms of computational modeling have sought to leverage findings in the social sciences to better describe—and maybe one day predict—how groups of people behave. One approach looks to update a widely used model to examine how changes in political opinions ripple through a group and how polarization can arise.

Bethe strings experimentally observed

Ninety years ago, the physicist Hans Bethe postulated that unusual patterns, so-called Bethe strings, appear in certain magnetic solids. Now, an international team has succeeded in experimentally detecting such Bethe strings for the first time. They used neutron scattering experiments at various neutron facilities, including the unique high-field magnet of BER II at HZB. The experimental data are in excellent agreement with the theoretical prediction of Bethe, and prove once again the power of quantum physics.

Belle II yields the first results: In search of the Z′ boson

The Belle II experiment has been collecting data from physical measurements for about one year. After several years of rebuilding work, both the SuperKEKB electron–positron accelerator and the Belle II detector have been improved compared with their predecessors in order to achieve a 40-fold higher data rate.

Bending microwaves and forbidding frequencies with simulated metamaterials

Using plasma to control microwaves for beaming direct energy toward a specific point is explored for their durability in high-energy electric fields and their reconfigurable structure. High power microwave beams, similar to lasers, can transmit energy at high speeds over long distances, unaffected by wind, gravity, or other forces. Aerospace engineers at the University of Illinois at Urbana-Champaign simulated a metamaterial formed from plasma structures to demonstrate its potential to tune microwave frequencies.

When Maxwell's demon takes its time: Measuring microparticle reaction time

Researchers at the Universities Vienna and Stuttgart have investigated a version of Maxwell's demon embodied by a delayed feedback force acting on a levitated microparticle. They confirmed new fundamental limits that time delay imposes on the demon's actions which are not covered by the standard laws of thermodynamics. The team of scientists published their new study in the journal Nature Communications.

Antibiotic matter waves: The quantum wave nature of a complex antibiotic polypeptide

One of the central tenets of quantum mechanics is the wave-particle duality. It tells us that even massive objects behave like both particles and waves. A number of previous experiments have shown this for electrons, neutrons, atoms and even large molecules. Quantum theory maintains that this is a universal property of matter. However, it had been notoriously difficult to extend this research to complex biomolecular systems. New experiments at the University of Vienna, supported by quantum chemical modeling at Stanford University, now demonstrate for the first time the quantum wave nature of a complex antibiotic polypeptide, here gramicidin. The results have been published in Nature Communications.

AI system that predicts movement of glass molecules transitioning between liquid and solid states

A team of researchers at Google's DeepMind has developed an AI system that is able to predict the movement of glass molecules as the material transitions between liquid and solid states. They have published a paper outlining their work on the DeepMind website.

Secure light-based communication through biological tissues

Visible light communications (VLC), and optical communications overall, caught professor Marcos Katz's interest when he and his team first demonstrated in 2017 a reconfigurable hybrid wireless network exploiting VLC and radio technologies. The network seamlessly switched from radio to optical, or vice versa, according to the condition of the channels, context information, local policies and others.

Astronomy and Space news

What makes Saturn's atmosphere so hot

The upper layers in the atmospheres of gas giants—Saturn, Jupiter, Uranus and Neptune—are hot, just like Earth's. But unlike Earth, the Sun is too far from these outer planets to account for the high temperatures. Their heat source has been one of the great mysteries of planetary science.

X-ray source 3XMM J000511.8+634018 is a polar, study suggests

Astronomers from Germany and France have investigated a newly discovered variable X-ray source known as 3XMM J000511.8+634018. Results of the new study suggest that the source is a polar. The finding is detailed in a paper published March 30 on the arXiv pre-print server.

Boeing to redo test flight of uncrewed Starliner spaceship

Boeing will relaunch an uncrewed test flight of its Starliner spaceship, the company said Monday, after an earlier mission failed due to multiple glitches.

Are gamma-ray bursts powered by a star's collapsing magnetic fields?

When a massive star in a distant galaxy collapses, forming a black hole, two giant jets of light-emitting plasma shoot from its core. These extremely bright gamma-ray bursts (GRBs) are the most powerful explosions in the universe, and when a jet points towards Earth, the afterglow can be detected from ground and space-borne telescopes. Material does not simply catapult from an exploding star, it accelerates to ultra-high speeds along the narrow beam of the gamma-ray jet, leaving astrophysics puzzled over the power source driving these extraordinary explosions. Now a new international study led by the University of Bath promises to shed light on this mysterious phenomenon.

Something is lurking in the heart of Quasar 3C 279

One year ago, the Event Horizon Telescope (EHT) Collaboration published the first image of a black hole in the nearby radio galaxy M 87. Now the collaboration has extracted new information from the EHT data on the distant quasar 3C 279: they observed the finest detail ever seen in a jet produced by a supermassive black hole. New analyses, led by Jae-Young Kim from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, enabled the collaboration to trace the jet back to its launch point, close to where violently variable radiation from across the electromagnetic spectrum arises.

First-ever photo proof of powerful jet emerging from colliding galaxies

A team of Clemson University College of Science researchers, in collaboration with international colleagues, has reported the first definitive detection of a relativistic jet emerging from two colliding galaxies—in essence, the first photographic proof that merging galaxies can produce jets of charged particles that travel at nearly the speed of light.

Innovative technologies for satellites

Some satellites are only slightly larger than a milk carton. This type of construction is now to be given a further simplified architecture and thus become even lighter and more cost-effective: This is the goal of the teams of Professors Sergio Montenegro of the University of W├╝rzburg and Enrico Stoll of the Technical University of Braunschweig, both in Germany.

Analytical model predicts exactly how much a piece of hardware will speed up data centers

Large-scale software services fight the efficiency battle on two fronts—efficient software that is flexible to changing consumer demands, and efficient hardware that can keep these massive services running quickly even in the face of diminishing returns from CPUs. Together, these factors determine both the quality of the user experience and the performance, cost, and energy efficiency of modern data centers.
