The Higgs boson, often dubbed the “God particle,” has been a focal point of physics since its groundbreaking discovery in 2012. This elusive particle plays a crucial role in our understanding of how elementary particles acquire mass, a concept that has puzzled scientists for decades. But the excitement doesn’t stop there. Seven years after its discovery, new findings from researchers at the Max Planck Institute are taking our knowledge of the Higgs boson to an entirely new level. These advancements promise to unravel deeper mysteries of the universe and open doors to future scientific exploration.

To fully appreciate the recent developments in Higgs boson research, it’s important to revisit the concept of this fundamental particle. In the Standard Model of particle physics, the Higgs boson is the particle responsible for giving mass to other particles. But how exactly does this happen? The answer lies in the Higgs field—a sort of invisible “medium” that permeates the universe, even in a vacuum.

Imagine you’re trying to walk through a swimming pool. When the water is still, you move easily, but if the pool were filled with foam, your movements would slow down considerably. The Higgs field operates similarly, with particles gaining mass as they interact with it, much like how a swimmer would find it harder to move through foam. The more a particle interacts with this field, the more mass it acquires, which allows particles to form the building blocks of matter as we know it.

Mathematician Stephen Wolfram has attempted to develop a theory of everything using hypergraphs, which are essentially sets of graphs that can describe space-time. Recently, another mathematician named Jonathan Gorard has used hypergraphs to describe what happens if a black hole accretes matter. He claims that evidence for hypergraphs should be observable in the energy that is emitted during the accretion. Big if true, as they say. Let’s take a look.

Perched in the constellation Orion, 1,300 light-years from Earth, lies GW Orionis, a unique triple-star solar system. Unlike most known systems, GW Orionis features two stars orbiting each other closely, while a third star circles at a much greater distance. Surrounding these stars are three enormous, misaligned rings of planet-forming dust, creating a striking bullseye pattern in the sky.

Recent studies, published in Science and The Astrophysical Journal Letters, suggest that these rings may harbor a young planet—or the makings of one. This celestial body could explain the dramatic misalignment of the system’s inner ring, which appears to wobble like a broken gyroscope. If confirmed, this would be the first known planet orbiting three stars simultaneously.

Nienke van der Marel, astrophysicist and co-author of the May 21 study, noted that the combined gravitational pull of the three stars alone cannot account for the rings’ behavior. Instead, the presence of a planet carving a gap in the disk could be disrupting the system’s balance.

Though he doesn’t remember it, Branden Baptiste had his first sickle cell crisis at age 2. Through elementary school, he was in and out of the hospital with pain episodes, not knowing why. As he got older, he learned he had sickle cell disease. His red blood cells were forming sickle shapes and getting stuck in his blood stream, preventing oxygen from reaching his tissues.

“Sickle cell disease has a broad spectrum of severity, and the severity and frequency of complications can wax and wane,” says Matthew Heeney, MD, Branden’s long-time hematologist at Boston Children’s Hospital.

What’s the best way to precisely manipulate a material’s properties to the desired state? It may be straining the material’s atomic arrangement, according to a team led by researchers at Penn State. The team discovered that “atomic spray painting” of potassium niobate, a material used in advanced electronics, could tune the resulting thin films with exquisite control.

The finding, published in Advanced Materials (“Colossal Strain Tuning of Ferroelectric Transitions in KNbO 3 Thin Films”), could drive environmentally friendly advancements in consumer electronics, medical devices and quantum computing, the researchers said.

The process, called strain tuning, alters a material’s properties by stretching or compressing its atomic unit cell, which is the repeating motif of atoms that builds up its crystal structure. The researchers use molecular beam epitaxy (MBE), a technique that involves depositing a layer of atoms on a substrate to form a thin film. In this case, they produced a thin film of strain-tuned potassium niobate.

Investigating how proteins interact is key to understanding how cells work and communicate. In a new study published in Nature Communications, FMI researchers have provided key insights into how protein interactions are governed and how mutations influence cellular functions.

Proteins are the molecular machines of life, performing tasks ranging from driving chemical reactions to orchestrating cell communication. For these tasks, proteins must bind to the right partners with precision, avoiding mispairings that could disrupt cellular processes and lead to disease.

Scientists have long been curious about how changes in the sequence of amino acids —the building blocks of proteins—can alter a protein’s binding capabilities. To investigate this question, researchers in the Diss lab analyzed the effects of all possible mutations in a single protein across its interactions with an entire family of partner proteins. They focused on a protein called JUN, which plays a key role in DNA binding and cellular communication.

A new way of mapping activity and connections between different regions of the brain has revealed fresh insights into how higher order functions like language, thought and attention, are organized.

Traditional models of human brain activity represent interactions in pairs between two different brain regions. This is because modeling methods have not developed sufficiently to describe more complex interactions between multiple regions.

A new approach, developed by researchers at the University of Birmingham is capable of taking signals measured through neuroimaging, and creating accurate models from these to show how different brain regions are contributing to specific functions and behaviors. The results are published in Nature Communications.

An experiment more than 10 years in the making has delivered its first glimpse of the hurricane of particles whirring inside subatomic particles called neutrons, laying the groundwork to solve a mystery deep in the heart of matter.

Data from the Central Neutron Detector at the US Department of Energy’s Thomas Jefferson National Accelerator Facility (TJNAF) is already playing a role in describing the quantum map of the neutron’s engine.

“It’s a quite important result for the study of nucleons,” says Silvia Niccolai, a research director at the French National Centre for Scientific Research.
