Medical Xpress / Coordinated brainstem slow waves may determine when it's time for REM sleep
Sleep is one of the most widely studied states of consciousness, known to play a role in physical recovery, the processing of memories and the regulation of immune functions. During sleep, the brain transitions between light ...
Phys.org / Bullet Cluster observations reopen dark matter debate with MOND-compatible explanation
The Bullet Cluster has so far been considered evidence of the existence of dark matter. An international team of researchers has now analyzed new data and current images from the James Webb Space Telescope (JWST). According ...
Phys.org / Building more apartments won't ease housing crisis
Building more apartments will not solve Australia's housing affordability crisis unless policymakers address rising house prices and investor activity, new research shows. Australia's housing affordability crisis is being ...
Phys.org / 'Timescapes' may help explain how animal species perceive events so differently in time
There is evidence that nonhuman animals perceive the world, and how it unfolds in time, differently from humans and from each other. For example, certain beetles can see flickering in lights up to around 500 Hz, while in ...
Phys.org / Hidden electric space waves are quietly cleaning Earth's 'killer' electrons
High above our heads, a silent battle is unfolding within Earth's magnetic shield. For decades, scientists have tracked "killer electrons"—ultrafast particles capable of piercing satellite armor and endangering astronauts ...
Phys.org / New JWST images of abnormally well-developed galaxy cluster open up the 'cosmic noon' frontier
A stunningly concentrated and hefty galaxy cluster, from a time in the universe's history when such massive structures aren't expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of ...
Phys.org / Bow-and-arrow-shaped radio galaxy discovered by citizen scientist
Astronomers have discovered a "remarkable" bow-and-arrow-shaped radio galaxy with an enormous arc-like structure extending nearly 1.8 million light-years across. The newly identified system, detailed in a new paper published ...
Phys.org / Human sacrifice in Inca Empire may have been driven by political motives, not religion
Three decades ago, researchers working atop the Llullaillaco volcano, located on the border between Argentina and Chile, discovered exceptionally well-preserved remains. The find included the mummified bodies of three children ...
Phys.org / Well-known planetary nebula's ear-like lobes rewrite its evolutionary timeline
Using the Multi Unit Spectroscopic Explorer (MUSE) and the Manchester Echelle Spectrograph (MES), astronomers from Turkey and Mexico have investigated a planetary nebula discovered two centuries ago, known as NGC 6563. Results ...
Phys.org / El Niño is underway, satellite observations show
El Niño, characterized by warmer-than-normal water temperatures in parts of the equatorial Pacific, made its return in June 2026. Observations of sea surface height from the Sentinel-6 Michael Freilich satellite that month ...
Medical Xpress / Molecular cause of age-related cognitive decline identified
A research team from University Hospitals, Case Western Reserve University and the Louis Stokes Cleveland VA Medical Center has identified a critical molecular cause of age-related cognitive decline, potentially paving the ...
Phys.org / Primordial halo simulations reveal how cosmic storms shaped the universe's first stars
Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon or oxygen. Instead, vast clouds of ...
