Holocene between 6,300 and 7,600 years ago, exhibited similar patterns of tooth wear and poor oral health, reinforcing the theory that these practices were established traditions. Historical distribution of betel chewing and elements of the betel quid –...

patterns are a primary feature rather than a secondary result of asteroid-based alteration. These findings reinforce the theory that carbonaceous chondrites were significant delivery vehicles for the chemical precursors of life, providing a clearer look...

view of the exoplanet’s orbital geometry and atmospheric velocity pattern. Credit: Astronomy & Astrophysics One potential theory suggests that the host star may have historically captured a secondary, misaligned disk of gas and dust. If the planet...

of the ship. Linking the Wreck to the 1856 St. Anthony While definitive identification is ongoing, the primary theory suggests the site contains the remains of the St. Anthony, a schooner built in Erie, Pennsylvania. Historical accounts from the Buffalo...

health. Watching Atmospheric Chemistry in Real Time For decades, the existence of Criegee intermediates was accepted in theory, first proposed by organic chemist Rudolf Criegee in the 1940s. However, their incredibly brief lifespan made them nearly...

remarkably early, likely within 2 million years of the formation of the first solar solids. Such a timeline supports the theory that these asteroids formed in a region where water ice could stabilize, facilitating the rapid growth of planetesimals...

transported the remains of these primary burials from elevated positions down into the lower-lying special buildings. This theory effectively accounts for the broad dispersion of bones across a 3,000-square-meter area, a pattern that differs...

mice noticed that liver cells lacking both primary reductase systems remained viable. This contradiction to established theory prompted a multi-year investigation led by Ed Schmidt, a professor of genetics and development at Montana State University. By...

Scientists debate a South African rock painting that may show a 200‑million‑year‑old dicynodont, but a peer A puzzling figure painted on a sandstone shelter in South Africa’s Free State has reignited a debate over whether Indigenous San artists may...

A tiny Wyoming sandstone fossil suggests the known story of an ancient primate group is incomplete, reshaping our evolutionary understanding. A newly identified primate species from the early Eocene of present‑day Wyoming, Tetonius varleyorum, measured...

Archaeologists may have discovered a lost royal tomb, uncovering monumental architecture and inscriptions that hint at a significant historical burial. A prominent burial site in Judea, long venerated by Christian pilgrims as the final resting place of...

Two mathematicians solve the 3D Kakeya conjecture after 50 years, a breakthrough hailed as a once‑in‑a‑century discovery. Picture a pencil suspended in mid‑air and spun so that it points toward every possible orientation, while the region it sweeps out...

The 1961 Idaho reactor explosion ended in milliseconds, yet its cause and lingering design flaws still spark debate decades later. On the morning of 3 January 1961, a routine restart of the Army’s SL‑1 reactor in Idaho went tragically wrong when the...

Scientists propose a bold plan to protect Earth from the Sun’s deadly expansion billions of years in the future. In roughly a billion years the Sun will exhaust its nuclear fuel and swell into a red giant, a transformation that could strip Earth of its...

Ancient fossil bones from Colombia reveal evidence of massive crocodilians hunting giant mammals, offering a rare glimpse into an intense prehistoric ecosystem. Paleontologists have uncovered the first direct physical evidence that massive crocodylians...

New NASA Mars imagery provides a scientific explanation for mysterious rock formations previously linked to sensationalist claims of extraterrestrial life. A retired professor of entomology has proposed a controversial hypothesis, suggesting that...

New ALMA images reveal persistent hot spots in Betelgeuse’s atmosphere, and a mysterious stellar companion may explain their unusual alignment. Fresh, high-resolution imagery of the red supergiant Betelgeuse has revealed a chaotic and increasingly...

New simulations reveal how giant impacts shaped icy moons and their hidden subsurface oceans over time, challenging our understanding of these frozen worlds. High-energy impacts in the outer reaches of the Solar System, once thought to be potential...

New research reveals that giant sunspots may enable the Sun to trigger rare and powerful superflares, potentially posing risks to our modern technology. New evidence suggests the Sun possesses the underlying mechanics to generate “superflares,” rare...

Archaeologists have unearthed over 52,000 Roman artefacts alongside a mysterious burial site that continues to defy conventional scientific explanation. In April 2010, a routine metal-detecting excursion in a field near Frome, Somerset, led to one of...
