Scientists plan to revive woolly mammoth by sperm injection
Geophysicist Daud Smale and Kazufui Goto seek preserved mammoth sperm to recreate the extinct species. Using permafrost radar to locate corpses in Siberia, they would, with elephants’ eggs, attempt staged breeding while facing skepticism from colleagues over DNA viability.

NASA finds clues from magnetic particles on Mars rocks
Matthew Golombek notes early data from Pathfinder magnets hint at maghemite cemented onto clay particles. If confirmed, this suggests long-term surface water activity. Sojourner and Pathfinder outlived expectations, 11 weeks in. A photo of rock Chim p shows fine texture and wind tails from the wind.
