Researchers from Linköping University together with colleagues from Poland and Chile have confirmed a theory that proposes a connection between the complementarity principle and entropic uncertainty. Their study is published in the journal Science Advances.

“Our results have no clear or direct application right now. It’s basic research that lays the foundation for future technologies in quantum information and quantum computers. There’s enormous potential for completely new discoveries in many different research fields,” says Guilherme B Xavier, researcher in quantum communication at Linköping University, Sweden.

But to understand what the researchers have shown, we need to start at the beginning.

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with their collaborators, have achieved the first precise mass measurements of several exotic atomic nuclei. Using this mass data, they have determined the proton dripline for aluminum, phosphorus, sulfur, and argon elements, and proposed a new approach to uncover proton halo structures.

The results were published in Physical Review Letters on November 27.

The atomic nucleus is a quantum many-body system composed of protons and neutrons, typically exhibiting a size similar to that of neighboring nuclei. A halo is an exotic nuclear structure found in weakly bound nuclei, characterized by one or more valence nucleons that display an extended spatial distribution, resulting in a radius significantly larger than that of neighboring nuclei.

Major findings on the inner workings of a brittle star’s ability to reversibly control the pliability of its tissues will help researchers solve the puzzle of mutable collagenous tissue (MCT) and potentially inspire new “smart” biomaterials for human health applications.

The work is directed by Denis Jacob Machado—assistant professor in Bioinformatics at The University of North Carolina at Charlotte Center for Computational Intelligence to Predict Health and Environmental Risks (CIPHER)—and Vladimir Mashanov, staff scientist at Wake Forest Institute for Regenerative Medicine.

In “Unveiling putative modulators of mutable collagenous tissue in the brittle star Ophiomastix wendtii: an RNA-Seq analysis,” published recently in BMC Genomics, the researchers describe using advanced transmission electron microscopy (TEM), RNA sequencing, and other bioinformatics methods to identify 16 potential MCT modulator genes. This research offers a breakthrough towards understanding precisely how echinoderms quickly and drastically transform their collagenous tissue. The first author of the paper, Reyhaneh Nouri, is a Ph.D. student in UNC Charlotte’s Department of Bioinformatics and Genomics.

Cleveland Clinic Genome Center researchers have unraveled how immune cells called microglia can transform and drive harmful processes like neuroinflammation in Alzheimer’s disease. The study, published in the journal Alzheimer’s & Dementia, also integrates drug databases with real-world patient data to identify FDA-approved drugs that may be repurposed to target disease-associated microglia in Alzheimer’s disease without affecting the healthy type.

The researchers, led by study corresponding author Feixiong Cheng, Ph.D., hope their unique approach of integrating genetic, chemical and human health data to identify drug targets and corresponding drugs will inspire other scientists to take similar approaches in their own research.

Microglia are specialized immune cells that patrol our brains, seeking and responding to tissue damage and external threats like bacteria and viruses. Different types of microglial cells use different methods to keep the brain safe. Some may cause neuroinflammation—inflammation in the brain—to fight invaders or kickstart the repair process in damaged cells. Others may work to “eat” dangerous substances in the brain, and clean up damage and debris. However, during Alzheimer’s disease, new types of microglia can form that promote disease progression.

NASA’s Parker Solar Probe mission has detected magnetic distortions in solar wind, known as switchbacks. To better understand these phenomena, whose origins remain uncertain, a study was conducted by a network of collaborators. This study, published in the journal Astronomy & Astrophysics, reveals that solar jets can create similar disturbances without causing a complete reversal of the magnetic field.

NASA’s Parker Solar Probe mission revealed the presence of switchbacks, sudden and rapid reversals of the magnetic field in the solar wind. These peculiar phenomena, rarely observed near Earth, have captivated the scientific community due to their enigmatic origins. A leading theory suggests that switchbacks originate from solar jets, which are ubiquitous in the lower atmosphere of the sun.

To investigate their origins, a team of researchers from LPP, LPC2E, FSLAC, the University of Dundee and Durham University conducted 3D numerical simulations to replicate plasma behavior in the sun’s atmosphere. These simulations modeled solar jets and studied their propagation in solar wind.

The Zwicky Transient Facility has reached an incredible milestone: It has classified over 10,000 cosmic explosions that mark the deaths of massive stars and the feeding frenzies of vampire stellar remnants. These events, called supernovas, are undoubtedly some of the most fearsome and powerful events in the universe.

Since 2012, humanity has discovered almost 16,000 supernovas. The Zwicky Transient Facility (ZTF), which began operations in 2017 using the 48-inch telescope at Palomar Observatory, is responsible for almost two-thirds of these detections. That makes it the largest and arguably most successful supernova surveyor to date.

“There are trillions of stars in the universe, and about every second, one of them explodes,” California Institute of Technology astronomer Christoffer Fremling said in a statement. “Reaching 10,000 classifications is amazing, but what we truly should celebrate is the incredible progress we have made in our ability to browse the universe for transients, or objects that change in the sky, and the science our rich data will enable.”
