Astronomers have mapped the 3D structure of an exoplanet’s atmosphere for the first time, revealing powerful winds that transport elements like iron and titanium. Using all four telescope units of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), researchers uncovered complex weather patterns shaping the planet’s skies. This breakthrough paves the way for more detailed studies of atmospheric composition and climate on distant worlds.
Once thought impossible, quasicrystals revealed a hidden order that challenges our understanding of materials.
Their structure follows rules from higher dimensions, influencing both their mechanical and topological properties. Recent research has uncovered bizarre time-related behaviors in these crystals, suggesting deeper physical principles at play.
A Revolutionary Discovery in Crystallography.
“ tabindex=”0” acid reflux at a significantly faster rate than those without. This highlights the urgent need for a healthcare system that treats both mental and physical health together, rather than in isolation.
Depression’s Lasting Impact on Physical Health
Adults with a history of depression develop chronic physical conditions about 30% faster than those without, according to a study published on February 13 in PLOS Medicine. Researchers, led by Kelly Fleetwood from the University of Edinburgh, suggest that depression should be recognized as a “whole-body” condition, emphasizing the need for integrated care that addresses both mental and physical health.
A neutrino of record-breaking energy — 220 PeV — has been detected by the underwater KM3NeT telescope, marking a pivotal moment in astrophysics.
This tiny but powerful particle, born from the universe’s most extreme events, provides fresh clues about cosmic accelerators. While its exact origin remains unknown, scientists believe it could be the first detected cosmogenic neutrino. The discovery fuels new momentum for multi-messenger astronomy, with future observations expected to shed light on the deepest mysteries of the cosmos.
More pocked with craters than any other object in our solar system, Jupiter’s outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA’s Galileo spacecraft captured magnetic measurements near Callisto that suggested that its ice shell surface—much like that of Europa, another moon of Jupiter—may encase a salty, liquid water ocean.
But evidence for Callisto’s subsurface ocean has remained inconclusive, as the moon has an intense ionosphere. Scientists thought this electrically conductive upper part of the moon’s atmosphere might imitate the magnetic fingerprint of a salty, conductive ocean.
Now, researchers have revisited the Galileo data in more detail. Unlike in prior studies, this team incorporated all available magnetic measurements from Galileo’s eight close flybys of Callisto. Their expanded analysis much more strongly suggests that Callisto hosts a subsurface ocean.
The 3,000+ journals in the Springer Nature portfolio published over 482,000 articles in 2024, according to data published this week on a new research integrity page on the company’s website. The page also shares a data point you don’t typically get from publishers: 2,923 articles were retracted.
A dual-site electrocatalyst is developed to greatly enhance methanol production from CO2 reduction via a cascade process, taking advantage of molecular-scale CO spillover.
China has launched a global initiative to develop post-quantum cryptographic algorithms, diverging from US-led efforts.
Synthetic biologists have the know-how and ambition to retool whole genomes. But the hidden complexity of biological systems continues to surprise them.
The bibliometric infrastructure of citations has become an inescapable organising feature of academic life. Drawing on a range of evidence of the use and misuse of citations data, Stuart Macdonald argues its ubiquity has rendered authorship a questionable concept in modern scholarship.
