How quickly sediment accumulates on the seafloor appears to be the key factor determining whether fossils from different time periods become mixed together. A single layer of marine fossils can look like a snapshot of one ancient community even when the organisms preserved side by side actually lived hundreds or thousands of years apart. For […]
Dead Sea Scrolls May Solve a Decades-Old Mystery About the Qumran Calendar
A new study uses Hasmonean history and evidence from the Dead Sea Scrolls to address a decades-old mystery. For decades, researchers have debated whether the Qumran sect’s unusual 364-day calendar ever governed daily religious life or existed only as an idealized system. A Tel Aviv University study now proposes that both possibilities may be true […]
Scientists Discover a “Loose Cannon” Virus Enzyme That Rewires Nearly Every Protein in a Bacterial Cell
Scientists found that phages, viruses that infect bacteria, trigger widespread protein modifications inside host cells that help them evade bacterial immune defenses. When a phage infects a bacterium, it must overcome the cell’s defenses before those defenses can destroy the invading virus. Researchers have now uncovered an unusual strategy used by T7 phage: a single […]

Scientists Tracked Galápagos Sea Turtles for Years – What They Found Was Unexpected
Sea turtles are built for epic ocean journeys, yet some in the Galápagos rarely venture beyond their island neighborhood. Sea turtles are renowned for long migrations between feeding grounds and nesting beaches. They navigate using signals that include Earth’s magnetic field, ocean currents, and the sun, often returning to the region where they hatched when […]
Humanity’s Carbon Signature Is Now Embedded Deep in the Ocean
Carbon released by the Industrial Revolution has left a chemical fingerprint nearly everywhere scientists looked in the North Atlantic, including waters thousands of feet below the surface. Scientists have traced carbon from fossil fuel emissions deep into the North Atlantic by measuring shifts in the natural balance between the isotopes C-12 and C-13, revealing how […]
