Vital intertwining: Blood parasite’s chainmail-like DNA structure could inspire next-generation materials

As tough as medieval chainmail armor and as soft as a contact lens. This material is not taken from science fiction, it is a natural structure made of thousands of DNA circles interlinked with each other. Studying it can help us advance our knowledge in many fields, from biophysics and infectious diseases to materials science and biomedical engineering.

This topic is the subject of “Organisation and dynamics of individual DNA segments in topologically complex genomes,” an article that has been published in Nucleic Acid Research.

The study, which also appeared on the front cover of the journal, is the result of a collaboration between the Department of Physics of the University of Trento, with Guglielmo Grillo under the supervision of Luca Tubiana, and the Department of Physics and Astronomy of the University of Edinburgh, with Saminathan Ramakrishnan and Auro Varat Patnaik, supervised by Davide Michieletto.

Not everyone reads the room the same: Some brains perform a complicated assessment—while others take a shortcut

Are you a social savant who easily reads people’s emotions? Or are you someone who leaves an interaction with an unclear understanding of another person’s emotional state?

New UC Berkeley research suggests that those differences stem from a fundamental way our brains compute facial and contextual details, potentially explaining why some people are better at reading the room than others—sometimes, much better.

A new family of barium-based crystals reveals rules for structural changes

The ultimate goal of materials scientists is to design and create materials with precise structures and tailored properties. Predictive technologies have advanced significantly with the rise of AI, yet the delicate nature of chemistry, where even the smallest change can alter a material’s behavior, remains a challenge for building truly chemically intuitive frameworks.

In a recent study, a team of researchers from the US presented a homologous series of barium-based crystals, where the family of materials was built from the same molecular building blocks and capable of forming an infinite range of structures. The only differences among the versions are the size and the arrangement of the blocks, brought about by slight changes in the ratio of the two elements with different electron affinities.

What makes this set of materials unique is that knowing one member of a sequence allows you to predict the next. The researchers believe that understanding the relationship between small changes and a material’s overall chemistry can help improve AI frameworks for predicting and synthesizing new materials.

Shaking magnets with ultrafast light pulses reveals surprising spin control

An international team of researchers led by Lancaster University has discovered a highly efficient mechanism for shaking magnets using very short light pulses, shorter than a trillionth of a second. Their research is published in Physical Review Letters.

The discovery of new fundamental properties and phenomena in magnetic materials is essential for the development of faster and energy-efficient devices.

Using a very short electromagnetic pulse to shake the magnetization, researchers investigated its effect on the magnetization steering angle in two similar magnetic materials with different electronic orbitals. After shaking the magnet and subsequently analyzing its magnetic state, they found that interaction between orbital motion and spinning enables a 10-fold larger spin deflection by the light pulse than the one without such interactions.

A universal law could explain how large trades change stock prices

Financial markets are often seen as chaotic and unpredictable. Every day, traders around the world buy shares and sell assets in a whirlwind of activity. It looks like a system of total randomness—but is it really?

Scientists have long suspected that there is a hidden order under this noise, but it has been difficult to prove. Now, Yuki Sato and Kiyoshi Kanazawa of Kyoto University have provided some of the strongest evidence yet. By studying eight years of data from the Tokyo Stock Exchange (TSE), they have confirmed a long-standing hypothesis known as the square-root law (SRL) of price impact.

30,000 Brain Scans Reveal a Hidden Danger in Ultra-Processed Foods

Brain imaging of 30,000 people revealed that ultra-processed foods are associated with structural differences in the brain that could fuel overeating.

The study suggests that additives like emulsifiers may influence these effects. While some processed foods are beneficial, ultra-processed products pose a clear risk.

Brain imaging study reveals concerning links to ultra-processed foods.

New Microscope Makes an Invisible 2D Material Visible

A new microscopy technique allows scientists to see single-atom-thick boron nitride by making it glow under infrared light. Researchers from the Physical Chemistry and Theory departments at the Fritz Haber Institute have developed a new way to visualize boron nitride layers that are just one atom

Strange, Record-Breaking Gamma-Ray Explosion Lasted 7 Hours and Defies Explanation

Data collected using multiple NSF NOIRLab facilities reveal a gamma-ray burst that lasted more than seven hours and originated in a massive, extremely dust-rich galaxy. Gamma-ray bursts (GRBs) rank among the most extreme explosions known in the Universe, surpassed only by the Big Bang itself. Mos

New AI Model Is Shockingly Good at “Reading” Human Minds

A new AI model is demonstrating an unprecedented ability to anticipate human actions by interpreting visual and contextual cues in real time. Rather than simply reacting to movement, the system reasons about what people are likely to do next. Researchers from the Texas A&M University College
