Researchers propose the universe may be 26.7 billion years old, nearly twice current estimates, eliminating the need for dark matter and dark energy in a new cosmological model tested against astronomical observations.

Scientists recovered ancient proteins from Homo naledi fossils in South Africa’s Rising Star Cave, finding no evidence of male-specific markers in 23 teeth, suggesting a possible all-female burial site from hundreds of thousands of years ago.

Scientists used advanced microscopy and chemical analysis to investigate a severely damaged British silver coin from 1834, suggesting the distortion likely resulted from a manufacturing problem rather than wear or corrosion.

Scientists discovered ancient sheeppox virus DNA preserved in 1,000-year-old medieval manuscripts, revealing the disease has affected European livestock for over 3,500 years.

NASA reports Earth’s ozone hole expanded to its largest size in a decade during 2026, driven by unusual Antarctic weather patterns, though scientists confirm the ozone layer continues its gradual recovery.

Construction begins on the Deep Underground Neutrino Experiment in a former South Dakota gold mine, where scientists will study ghostly particles to unlock cosmic mysteries and fundamental physics questions.

Scientists at Dartmouth College found that conversations exhibiting ‘pink noise’ — a balance between stability and flexibility — are more enjoyable and strengthen connections between participants.

New research suggests comets likely destroyed rather than delivered life’s essential organic molecules to early Earth, challenging a nearly century-old scientific theory about the origins of life.

Paleontologists identified a 450-million-year-old crinoid fossil with exceptionally preserved soft tissue, offering rare insight into how ancient marine animals fed and evolved.

Astronomers using NASA’s Hubble Space Telescope have detected a 93-billion-mile cosmic structure called the “Cat’s Tail” around a young star system, likely the wreckage from colliding planetary bodies.

Astronomers have developed a computational technique using a digital model of the James Webb Space Telescope to remove starlight glare and reveal previously hidden exoplanets in existing observations.

Researchers in China have discovered a 237-million-year-old armored sea amphibian, the first known to spend its entire life in the ocean—a feat no modern amphibian can achieve.
