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 Discover a “Loose Cannon” Virus Enzyme That Rewires Nearly Every Protein in a Bacterial Cell

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 […]

Scientists Find TNT Leaking From a 100-Year-Old Submarine Wreck
Fierce naval battles in the North Sea during both world wars sent many ships to the seafloor. Their wrecks remain there today, leaking toxic chemicals that are absorbed by local plants and animals. In April 1917, the German submarine UC-30 was traveling beneath the North Sea near the Danish island of Rømø. Engine problems had […]
Brain Scans Reveal a Surprising Dopamine Difference in Autism
By analyzing three different types of brain scans, researchers uncovered new clues about the biological processes linked to autism. The results point to the dopamine system as a potentially important part of autism biology. Autism is associated with differences across several systems in the brain, but understanding how those differences connect has been difficult. Researchers […]
