Wolf-Rayet 104's Orbit Tilt Reduces Gamma-Ray Burst Threat, Study Finds
New research using Keck Observatory’s instruments confirms that the orbit of Wolf-Rayet 104 is tilted 30-40 degrees away from Earth, lowering concerns about a possible gamma-ray burst. Previously, it was believed that the system’s alignment could pose a risk. However, spectroscopy data now challenges these assumptions, raising new questions abo...

New Research Sheds Light on Iron’s Role in Earth’s Core Dynamics
Cutting-edge research using ultrafast X-ray absorption spectroscopy has revealed the structural and thermal behaviour of iron under extreme conditions mimicking Earth’s core. Findings show a hexagonal close-packed (hcp) structure at 240 GPa and 5,345 K, challenging prior theories favouring a body-centred cubic (bcc) form. The study provides criti...

MIT Researchers Measure Quantum Geometry of Electrons in Solid Materials for First Time
Physicists at MIT have successfully measured the quantum geometry of electrons in solids, marking a pivotal moment in quantum research. This was achieved using an advanced adaptation of angle-resolved photoemission spectroscopy (ARPES), enabling direct observation of quantum properties that were previously theoretical. The study, featured in Nature...

Semi-Dirac Fermions Found in ZrSiS: Quasiparticles with Directional Mass Behavior
Researchers at Penn State and Columbia University identified semi-Dirac fermions, quasiparticles theorized 16 years ago, in ZrSiS crystals. These particles are massless in one direction but have mass in another. The findings, published in Physical Review X, were made using magneto-optical spectroscopy at the National High Magnetic Field Laboratory....

NASA and JAXA’s XRISM Mission Captures Detailed Data from X-Ray Emitting Wolf-Rayet Star
NASA and JAXA’s XRISM mission recently produced a detailed analysis of Cygnus X-3, a high-mass binary system containing a Wolf-Rayet star and a likely black hole. Using high-resolution X-ray spectroscopy, scientists observed intricate gas dynamics involving the star’s stellar winds and interactions with its companion.

Japan’s XRISM Telescope Delivers Insights from a Supermassive Black Hole and a Supernova
Less than a year since Japan's X-Ray Imaging and Spectroscopy Mission (XRISM) launched, it has delivered its first results, uncovering crucial information about black holes and supernova remnants. XRISM is a collaborative effort between the Japan Aerospace Exploration Agency (JAXA) and the European Space Agency (ESA). Its observations have revealed...

Apple Reportedly Makes Advances in Developing Non-Invasive Blood Glucose Monitoring: Mark Gurman
Apple has reportedly hit a major milestone in the development of a prick-less glucose monitoring technology that could eventually makes its way to an Apple Watch. However, the protype device is currently the size of an iPhone, and therefore, could take a while until it actually makes its way to an Apple Watch.
