Phys.org / Third exoplanet detected in the planetary system HD 176986
Using HARPS and HARPS-N spectrographs, astronomers have observed a nearby K-type star designated HD 176986, known to host two super-Earth exoplanets. The observations resulted in the discovery of another planet in the system ...
Medical Xpress / How lung tumors use the brain to avoid immune attacks
University of Pennsylvania Perelman School of Medicine and Yale University School of Medicine, along with other collaborators, report that lung adenocarcinoma can engage nerve pathways that link the lung to the brainstem ...
Medical Xpress / AI algorithm enables tracking of brainstem's vital white matter pathways
The signals that drive many of the brain and body's most essential functions—consciousness, sleep, breathing, heart rate and motion—course through bundles of "white matter" fibers in the brainstem, but imaging systems ...
Phys.org / Muon Knight shift reveals the behavior of superconducting electron pairs
Quantum materials and superconductors are difficult enough to understand on their own. Unconventional superconductors, which cannot be explained within the framework of standard theory, take the enigma to an entirely new ...
Tech Xplore / Sunlight and liquid metal produce clean hydrogen from seawater with new 'harvest' method
Researchers have created a process using liquid metals, powered by sunlight, that can produce clean hydrogen from both freshwater and seawater. The method allows researchers to "harvest" hydrogen molecules from water while ...
Medical Xpress / San Bernardino County reports first measles case since 2023 as U.S. infections continue to climb
Health officials in San Bernardino County, California, have confirmed the first case of measles in the county since 2023. The county's Department of Public Health said the case involves an unvaccinated child who was visiting ...
Dialog / Scientists advance multi-purpose photocatalyst for clean hydrogen production and agricultural pollutant degradation
Can we use nothing more than sunlight and inexpensive materials to produce clean hydrogen fuel while also removing toxic pollutants from water? That question shaped our recent work with γ-In2S3, a semiconductor that has ...
Phys.org / 5,300-year-old 'bow drill' rewrites story of ancient Egyptian tools
A new study reveals that Egyptians were using a mechanically sophisticated drilling tool far earlier than previously suggested. Researchers at Newcastle University, and the Academy of Fine Arts, Vienna, have re-examined a ...
Phys.org / A smashing success: Relativistic Heavy Ion Collider wraps up final collisions
Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion Collider (RHIC) and ...
Phys.org / People act more helpfully in poor environments than rich ones, research reveals
People are more likely to act helpfully in situations where there are poorer choices to give to others, according to a new study that tested willingness to help others in different contexts.
Phys.org / Seeing the whole from a part: Revealing hidden turbulent structures from limited observations and equations
The irregular, swirling motion of fluids we call turbulence can be found everywhere, from stirring in a teacup to currents in the planetary atmosphere. This phenomenon is governed by the Navier-Stokes equations—a set of ...
Phys.org / Why only a small number of planets are suitable for life
For life to develop on a planet, certain chemical elements are needed in sufficient quantities. Phosphorus and nitrogen are essential. Phosphorus is vital for the formation of DNA and RNA, which store and transmit genetic ...
