Credit ScitkeTo the casual observer, the Sun appears constant and unchanging. In reality, it is a turbulent sphere of seething plasma, where electrically charged gas is in constant motion, influenced by the Sun’s magnetic field. Understanding and predicting this chaotic activity remains one of the greatest challenges for modern solar physicists.One of the most...
X-ray spectrum in colors showing differences in alternamagnetic properties. (Amin et al., Nature, 2025)Physicists in Sweden have successfully controlled a newly discovered form of magnetism, opening exciting possibilities for advancements in electronics, from memory storage to energy efficiency.A team led by researchers from the University of Nottingham used high-speed electron accelerators to bombard an ultra-thin wafer...
Filtering spin with a helix. Credit: Angela WittmannElectrons are primarily known for their negative charge, which drives electric currents, but they also possess spin—a magnetic property with vast potential for advancing data storage technology. However, effectively controlling electron spin remains a challenge.Harnessing Spin Through Ferromagnetic Materials and Chiral MoleculesOne common method to align electron...
Light therapy shows promise in improving sleep and mood for Alzheimer’s patients, with minimal side effects, but larger studies are needed for confirmation. Credit: SciTechDaily.comA new study published in PLOS ONE suggests that light therapy may significantly improve sleep quality, strengthen circadian rhythms, and reduce caregiver burden in Alzheimer’s patients.Alzheimer’s not only impairs memory...
Credit: PixabayNeurons, the brain’s essential cells, form intricate networks by exchanging signals, enabling learning and adaptation. Researchers at Delft University of Technology (TU Delft) in the Netherlands have created a 3D-printed environment that closely resembles real brain tissue. Using nanoscale pillars, they replicate the soft, fibrous structure that supports neurons. This innovation provides a...
Credit: PixabayUsing multiple NASA telescopes, scientists have conducted a groundbreaking survey to detect both visible and hidden supermassive black holes—colossal objects billions of times more massive than the Sun. Nearly every large galaxy is thought to harbor one at its core, yet directly counting them is impossible. Instead, astronomers analyze smaller samples to estimate...

A new study reveals that a diet rich in nitrates—found in leafy greens and the Mediterranean diet—could promote beneficial oral bacteria linked to improved memory and reduced dementia risk.Researchers suggest that the microbial...
NASA astronaut Victor Glover tests collection methods for ISS External Microorganisms in the Neutral Buoyancy Lab at Johnson Space Center. (NASA)On January 30, astronauts Suni Williams and Butch Wilmore will embark on a 6.5-hour spacewalk outside the International Space Station (ISS). One key objective is collecting surface samples to study microbial presence on the station’s...
