Space junk falls to Earth faster when sunspots peak, reshaping satellite collision forecasts

A forgotten fossil hidden inside a garden wall has turned out to be one of Australia’s most remarkable prehistoric discoveries. Scientists have now identified the 240-million-year-old amphibian, Arenaerpeton supinatus, revealing an almost perfectly preserved skeleton—complete with rare traces of skin. This ancient river predator, about 1.2 meters long, looked somewhat like a giant salamander but was bulkier and armed with fearsome fang-like teeth.

When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating electric and magnetic field variations that can resemble fainter signals from natural hazards. This risk is not theoretical.

Oak trees have a surprising trick to fight back against hungry caterpillars: they simply wait. When trees are heavily attacked one year, they delay leaf growth by just three days the next spring—long enough to leave newly hatched caterpillars with nothing to eat. This small shift slashes insect survival and reduces leaf damage by more than half, proving even more efficient than costly chemical defenses.
