Triple threat: The first observation of three massive gauge bosons produced in proton-proton collisions

The Standard Model, the most exhaustive existing theory outlining fundamental particle interactions, predicts the existence of what are known as triboson interactions. These interactions are processes in which three-gauge bosons are simultaneously produced from one Large Hadron Collider event.

New semiconductor detector shows promise for medical diagnostics and homeland security

Security officials are tasked with preventing criminals from smuggling dangerous materials into a country, and detecting nuclear substances has been difficult and costly. Now Northwestern University researchers have developed new devices based on a low-cost material to aid in the detection and identification of radioactive isotopes.

A photonic curveball has real-world examples in soccer, baseball

Have you ever been amazed by a curveball goal scored by Diego Maradona, Lionel Messi or Christiano Ronaldo? Then you have—possibly without knowing it—been exposed to the Magnus effect: the fact that spinning objects tend to move along curved paths. In a new publication that appeared in Physical Review Letters this week, Robert Spreeuw shows that the same effect occurs to atoms moving through light—and that this effect has practical consequences.

The lightest light – the future of digital displays and brain science

A team of scientists from the University of St Andrews has developed a new way of making the most durable, lightweight and thinnest light source available so far, which could revolutionize the future of mobile technologies and pave the way for new advances in brain science.

Appearances can be deceiving: Display versus surface colors

The white of paper and the white of a monitor can be precisely the same color values, yet they appear fundamentally different. That disparity may not lie in the mode of display, but rather in how the colors are constructed, according to a research team at Yokohama National University in Japan.

Team develops component for neuromorphic computer

Neural networks are some of the most important tools in artificial intelligence (AI): they mimic the operation of the human brain and can reliably recognize texts, language and images, to name but a few. So far, they run on traditional processors in the form of adaptive software, but experts are working on an alternative concept, the 'neuromorphic computer.' In this case, the brain's switching points—the neurons—are not simulated by software but reconstructed in hardware components. A team of researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has now demonstrated a new approach to such hardware—targeted magnetic waves that are generated and divided in micrometer-sized wafers. Looking to the future, this could mean that optimization tasks and pattern recognition could be completed faster and more energy efficiently. The researchers have presented their results in the journal Physical Review Letters.

Researchers develop unique process for producing light-matter mixture

A neglected mechanism in antiferromagnets may be key to spintronics

Enormous efforts are being made worldwide in a technological field that could far surpass the capabilities of conventional electronics: Spintronics. Instead of operating based on the collective movement of charged particles (electrons), spintronic devices could perform memory storage and data transmission by manipulating spin, an intrinsic property of elementary particles related to angular momentum and from which many magnetic characteristics in materials arise. Unfortunately, controlling spin has proven to be a challenging endeavor, leading physicists and engineers to look for efficient materials and techniques to do so.

Astronomy and Space news

Two young planetary systems detected by TESS

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new young planetary systems. They found that two stars not older than 320 million years, namely TOI-251 and TOI-942, are orbited by a mini-Neptune planet and two Neptune-sized exoplanets. The finding is reported in a paper published November 26 on

Chinese probe orbiting moon with Earth-bound samples

A Chinese probe was orbiting the moon on Monday in preparation for the returning of samples of the lunar surface to Earth for the first time in almost 45 years.

Carbon emission from star-forming clouds

The carbon atom can be easily ionized, more easily than hydrogen atoms for example. In star forming regions, where massive young stars emit ultraviolet light capable of ionizing atoms, all the neutral carbon nearby becomes ionized. The singly-ionized carbon atom (abbreviated CII) emits a strong line in the far infrared that is both very intense and consequently a reliable proxy for the ultraviolet flux from star formation activity. In some extreme star forming galaxies, the energy in this one infrared CII line alone can be as much as one percent of the entire energy budget of the galaxy. The extreme brightness of the line makes it a very powerful tool for studying cosmically remote galaxies in the early universe because it is one of the easiest lines to detect and its measured wavelength, shifted by expansion of the universe, provides a precise measure of the galaxy's distance. All this means that astronomers are working towards a more precise understanding of how and where carbon is ionized by young stars. One major outstanding puzzle is that in some bright star-forming galaxies the strength of the CII emission is as much as one hundred or more times weaker than it is in the strongest cases, and the reason is not well understood.

New sunspot cycle could be one of the strongest on record, new research predicts

In direct contradiction to the official forecast, a team of scientists led by the National Center for Atmospheric Research (NCAR) is predicting that the Sunspot Cycle that started this fall could be one of the strongest since record-keeping began.

Image-based navigation could help spacecraft safely land on the moon

Safe space: Improving 'clean' methanol fuel cells using a protective carbon shell

Because of environmental problems caused by the use of fossil fuels, many scientists worldwide are focused on finding efficient alternatives. Though high hopes have been placed on hydrogen fuel cells, the reality is that transporting, storing and using pure hydrogen comes with a huge cost, making this process challenging with current technology. In contrast, methanol (CH3O3), a type of alcohol, does not require cold storage, has a higher energy density and is easier and safer to transport. Thus, a transition to a methanol-based economy is a more realistic goal.

There are plenty of obstacles standing in the way of developing the first zero-emission, hydrogen-powered plane. It's tricky to safely store and use the highly combustible fuel. There aren't any airports equipped to refuel jets with it. And the cost of hydrogen itself is prohibitive, at least if you want to avoid producing greenhouse gases.

Bend, don't break: New tool enables economic glass design

Curved glass fa├žades can be stunningly beautiful, but traditional construction methods are extremely expensive. Panes are usually made with 'hot bending,' where glass is heated and formed using a mold or specialized machines, an energy-intensive process that generates excess waste in the form of individual molds. Cold-bent glass is a cheaper alternative in which flat panes of glass are bent and fixed to frames at the construction site. However, given the fragility of the material, coming up with a form that is both aesthetically pleasing and manufacturable is extremely challenging. Now, an interactive, data-driven design tool allows architects to do just that.
