Atlantic dolphins are dying much younger. Scientists sound the alarm Common dolphins in the North Atlantic are living significantly shorter lives, with female longevity dropping seven years since the 1990s. Researchers found this decline by analyzing stranded dolphins, revealing a 2.4% drop in population growth linked to bycatch deaths and environmental pressures. The findings expose flaws in traditional counting methods and call for adaptive conservation measures, such as smarter fishing restrictions.

Scientists just found hidden life thriving beneath the Arctic ice Melting Arctic ice is revealing a hidden world of nitrogen-fixing bacteria beneath the surface. These microbes, not the usual cyanobacteria, enrich the ocean with nitrogen, fueling algae growth that supports the entire marine food chain. As ice cover declines, both algae production and CO2 absorption may increase, altering the region’s ecological balance. The discovery could force scientists to revise predictions about Arctic climate feedbacks.

MIT finds traces of a lost world deep within planet Earth Researchers have discovered chemical fingerprints of Earth's earliest incarnation, preserved in ancient mantle rocks. A unique imbalance in potassium isotopes points to remnants of “proto Earth” material that survived the planet’s violent formation. The study suggests the original building blocks of Earth remain hidden beneath its surface, offering a direct glimpse into our planet’s ancient origins.

A giant asteroid hit Earth, but its crater is missing Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically from other known tektites. Although the crater remains missing, the find exposes a massive event once thought unrecorded, offering clues to Earth’s tumultuous past and planetary defense.

Forged in fire: The 900°C heat that built Earth’s stable continents New research reveals that Earth’s continents owe their stability to searing heat deep in the planet’s crust. At more than 900°C, radioactive elements shifted upward, cooling and strengthening the landmasses that support life. This ancient heat engine also distributed valuable minerals, giving scientists new clues for exploration and for spotting potentially habitable planets.
