Hidden Warm-Water Tunnels: Seafloor channels funnel heat to Totten Glacier; scientists probe future changes
Beneath East Antarctica's Totten Glacier, hidden undersea valleys are channeling warm ocean water, melting its ice shelf from below. This discovery reshapes our understanding of glacial stability, revealing that the glacier, which could raise sea levels by over 3.5 meters if melted, is vulnerable to oceanic currents through these secret routes. Scientists are now investigating the extent of this warming.
Shechtman’s 10-Fold Symmetry Note: alloy defied crystal rules; quasicrystals reshaped materials science
In 1982, materials scientist Dan Shechtman observed an unusual tenfold symmetry in an aluminum-manganese alloy, defying the established definition of crystals. Despite initial skepticism and resistance from the scientific community, his persistent research led to the discovery of quasicrystals, a new form of atomic ordering. This groundbreaking finding revolutionized crystallography and earned Shechtman the Nobel Prize in Chemistry.
Trees cut extra city heat by half, but not quite where most needed
City trees serve as essential green shields, absorbing heat and providing relief from the suffocating warmth generated by urban structures. However, the impact is starkly diminished in hotter, low-income areas where their cooling shade is desperately needed. While urban forestry globally cools cities by an average of 0.
