Quantum Gravity Signals May Be Optical Illusions, Study Suggests
Researchers propose that some experiments thought to demonstrate quantum gravity may instead be explained by quantum particles in classical spacetime, suggesting an important ambiguity in how gravity experiments are interpreted.
Telescopio Roman de la NASA se prepara para revelar los misterios del universo
La NASA se prepara para lanzar el telescopio espacial Roman, un observatorio de 12 metros y 4.000 millones de dólares que mapeará el cosmos y estudiará misterios como la materia oscura y energía oscura.
Ordinary matter comprises just 4.9% of universe's mass-energy budget
Planck satellite data shows ordinary matter comprises only 4.9% of the universe's mass-energy budget, with dark matter at 26.8% and dark energy at 68.3%, representing current cosmological model estimates rather than direct inventory.
Fifth-grader's classroom molecule model becomes published scientific discovery
A fifth-grader in Kansas City built an unprecedented molecular structure with a classroom model kit, leading to peer-reviewed publication and a hypothetical compound with explosive potential.
NASA's Roman telescope launches Sunday on mission to map cosmos and solve physics mysteries
NASA launches its $4 billion Roman Space Telescope on Sunday to map the cosmos and investigate dark matter and dark energy, the universe's greatest mysteries.
Senescent 'Zombie' Cells Identified as Major Driver of Chronic Inflammation
Research reveals that senescent "zombie" cells drive chronic inflammation through cyclin D1–CDK6 activity, offering potential therapeutic targets for age-related diseases.
Lab experiment confirms diamond rain occurs inside Neptune and Uranus
Lawrence Livermore scientists experimentally confirmed that diamonds melt and rain inside Neptune and Uranus, resolving a 20-year physics mystery while revealing potential to triple fusion energy output.
Light's Speed Advantage: Why Earth Would Hear the Sun's Roar 14 Years After Going Dark
A thought experiment illustrates the vast speed difference between light and sound: if the Sun vanished, Earth would darken in 8 minutes, but hypothetical sound would take nearly 14 years to reach us.
If the Sun vanished, its light would reach us in 8 minutes—sound would take 14 years
A thought experiment compares how long it would take light versus sound to travel from the Sun to Earth, revealing light arrives in 8 minutes while sound would take 13.82 years through hypothetical air.
NASA Installs Four Space Shuttle Engines on Artemis III Rocket as Mission Nears
NASA has begun installing four RS-25 engines on the Space Launch System core stage for the Artemis III mission, which will conduct crewed tests in low Earth orbit before eventual lunar operations.
Unexplained fatigue: The overlooked heart attack warning sign in women
Research shows up to 70% of women experience unexplained fatigue days or weeks before a heart attack, yet doctors and patients often dismiss it as stress or exhaustion, delaying critical care.
NASA's Swift Rescue Mission Pivots After Spacecraft Malfunction
NASA and Katalyst Space's LINK spacecraft will attempt rendezvous with the aging Swift Observatory despite an attitude control failure, prioritizing data collection for future satellite servicing missions.
Study: Physical exams alone unreliable for diagnosing childhood pneumonia
A national study finds doctors inconsistently identify lung sounds when diagnosing pneumonia in children, suggesting physical exams alone may be insufficient and better diagnostic tools are needed.
Study: Adolescents Report High Satisfaction After Gender-Affirming Chest Surgery
A new study finds adolescents who undergo gender-affirming chest surgery report low regret rates and high satisfaction with their outcomes.
Study finds adolescents report high satisfaction, low regret after gender-affirming chest surgery
Research shows adolescents undergoing gender-affirming chest surgery report high satisfaction and low regret comparable to young adults, challenging policy arguments for age restrictions.
NASA's Roman Space Telescope Launches Sunday to Revolutionize Cosmic Discovery
NASA's Roman Space Telescope, a $4.3 billion observatory with a 300-megapixel camera, launches Sunday to scan the cosmos 1,000 times faster than Hubble, expected to discover over 100,000 exoplanets and probe dark matter and energy.
NASA lanzará el telescopio Nancy Grace Roman con capacidad 100 veces mayor que Hubble
La NASA lanzará el telescopio Nancy Grace Roman desde Cabo Cañaveral a bordo de un cohete Falcon Heavy, nueve meses antes de lo previsto. El observatorio panorámico más grande jamás construido monitoreará más de 2 mil galaxias con un campo de visión 100 veces mayor que el Hubble.
Nanoscale Wrinkles Transform Graphene Into Tiny Batteries, Study Finds
US and UK researchers discovered that microscopic wrinkles in graphene create electrical charge through flexoelectricity, potentially enabling new material designs controlled by structure rather than chemistry.
Wrangel Island mammoths thrived genetically, then vanished mysteriously 4,000 years ago
A 2024 genetic study reveals woolly mammoths on Wrangel Island maintained stable populations for 6,000 years despite extreme inbreeding, then disappeared abruptly 4,000 years ago from an unknown cause.
Moon in Waning Gibbous Phase on August 29, 2026

Epicurus's Ancient Cure: Why Freedom From Fear Matters More Than Pleasure
An editorial exploration of Epicurus's philosophy reveals his actual teaching was about freedom from pain and fear, not hedonism, with fear of death as the root cause of anxiety.
Astronomers Rethink Universal Mass Measurement as Star Formation Assumptions Crumble
Astronomers are reconsidering the initial mass function (IMF), a decades-old mathematical tool for estimating galaxy masses. University of Missouri researchers found that star formation ratios vary by environment, suggesting the IMF needs environment-specific adjustments rather than universal application.
