Scientists have found a unique geological and biological complex deep in the Greenland Sea. Methane hydrate mounds, formed by trapped methane and ice, were discovered along the Molloy Ridge. These mounds support chemosynthetic organisms, life that thrives without sunlight. This discovery offers new insights into Arctic oceanography and methane stability.

Scientists are engineering electromagnetic waves to retrace their temporal paths, a breakthrough in wave physics. This 'time reversal' doesn't involve historical travel but reverses a wave's sequence, enabling frequency shifts and precise signal manipulation. This innovative approach, demonstrated through 'time interfaces,' promises significant advancements in communications, imaging, and signal control, pushing the boundaries of physical design.

Astronauts do not need sunscreen in space because their advanced spacesuits and spacecraft windows are designed to block harmful UV radiation. These engineered protections, rather than topical lotions, ensure safety from the Sun's harsh rays during extravehicular activities and inside habitats. A rare suit tear did cause one astronaut sunburn, highlighting the critical role of this technology.
