Aloof neutrons may actually 'talk' to one another briefly in new kind of symmetry

Even though neutrons love to partner with protons to make the nucleus of an atom, the particles have always been notorious for their reluctance to bind with each other. But according to a new proposed theory, these particles might communicate under certain circumstances, forming a new sort of 'unparticle'—which could offer evidence of a new kind of symmetry in physics.

Physicists find 'magnon' origins in 2D magnet

Rice physicists have confirmed the topological origins of magnons, magnetic features they discovered three years ago in a 2D material that could prove useful for encoding information in the spins of electrons.

Ultrafast electronic control of magnetic anisotropy by mid-infrared light

One of the most important tasks in modern information technologies is controlling spin directions in magnets. State-of-the-art hard disk drives and large-volume magnetic storage used in data centers require magnetization in solids to switch their directions in nanoseconds, corresponding to GHz frequency, or even faster speeds. An ever-increasing demand for writing speed has pushed researchers towards extensive research in optical techniques using femtosecond laser pulses.

Gap solitons break one-dimensional coherent atomic systems

As the core of the light field modulation technologies, optical lattice has highly tunability and is usually used to manipulate the nonlinear matter waves of Bose-Einstein condensate (BEC). At present, the mainstream researches focus on coherent atomic systems like BECs which have been confirmed to be able to stably generate optical solitons under electromagnetically induced transparency (EIT) mode. However, related studies are limited to the periodic physical system in one dimension.

By analyzing the data from NASA's Fermi spacecraft and Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescope, an international team of astronomers has investigated a millisecond pulsar known as PSR J0218+4232. Results of the study, published August 25 on arXiv.org, shed more light on the emission from this source.

What young stars teach us about the birth of our solar system

The familiar star at the center of our solar system has had billions of years to mature and ultimately provide life-giving energy to us here on Earth. But a very long time ago, our sun was just a growing baby star. What did the sun look like when it was so young? That's long been a mystery that, if solved, could teach us about the formation of our solar system—so-named because sol is the Latin word for sun—and other stellar systems made up of planets and cosmic objects orbiting stars. 

The case of the missing mantle: How impact debris may have disappeared from the solar system

In the early solar system, terrestrial planets like Mercury, Venus, Earth and Mars are thought to have formed from planetesimals, small early planets. These early planets grew over time, through collisions and mergers, to make them the size they are today.

China wants to build a spaceship that's kilometers long

It's no secret that China has become a major contender in spaceflight. In the past 20 years, the China National Space Agency (CNSA) has accomplished some historic firsts. This includes sending astronauts to space, deploying three space stations (as part of the Tiangong program), developing heavy launch vehicles (like the Long March 5), and sending robotic explorers to the far side of the moon and Mars.

Over the past few decades, roboticists and computer scientists have developed robots that can grasp and manipulate various objects in their surroundings. Most of these robots are primarily trained to grasp rigid objects or objects with specific shapes.

Imaginary numbers protect AI from very real threats

Computer engineers at Duke University have demonstrated that using complex numbers—numbers with both real and imaginary components—can play an integral part in securing artificial intelligence algorithms against malicious attacks that try to fool object-identifying software by subtly altering the images. By including just two complex-valued layers among hundreds if not thousands of training iterations, the technique can improve performance against such attacks without sacrificing any efficiency.

Making the case for hydrogen in a zero-carbon economy

As the United States races to achieve its goal of zero-carbon electricity generation by 2035, energy providers are swiftly ramping up renewable resources such as solar and wind. But because these technologies churn out electrons only when the sun shines and the wind blows, they need backup from other energy sources, especially during seasons of high electric demand. Currently, plants burning fossil fuels, primarily natural gas, fill in the gaps.

New scientific approach reduces bias in training data for improved machine learning

As companies and decision-makers increasingly look to machine learning to make sense of large amounts of data, ensuring the quality of training data used in machine learning problems is becoming critical. That data is coded and labeled by human data annotators—often hired from online crowdsourcing platforms—which raises concerns that data annotators inadvertently introduce bias into the process, ultimately reducing the credibility of the machine learning application's output.

New report details Switzerland's geo-energy potential

When the Swiss government decided to phase out nuclear power in the wake of the Fukushima accident on 11 March 2011, it also launched a major nationwide research program to explore alternative energy sources, with the goal of fully replacing the country's nuclear power with renewable energy by 2050. Some CHF 250 million in funding was deployed to develop and implement a comprehensive strategy. The nationwide research program entailed setting up eight Swiss Competence Centers for Energy Research (SCCERs) to explore seven energy-related topics. Universities and research institutes from across the country, in association with around 900 businesses and public-sector organizations, conducted 1,500 research projects through these Centers between 2013 and 2020. Innosuisse was commissioned to evaluate the results of the projects, and it issued its final report on 22 July 2021.

Increased advertising and algorithm changes at Google may make it harder to find what you're looking for

Over the past 25 years, the name "Google" has become synonymous with the idea of searching for anything online. In much the same way "to Hoover" means to use a vacuum cleaner, dictionaries have recognized "to Google" as meaning to undertake an online search using any available service.

Biofuels offer a cost-effective way to lower shipping emissions
