After 20 years, scientists finally shrink a powerful laser onto a chip
After 20 years, scientists finally shrink a powerful laser onto a chip - Date: - June 4, 2026 - Source: - Ecole Polytechnique Fédérale de Lausanne - Summary: - Researchers at EPFL have developed a chip-scale ultrafast laser that performs on par with traditional tabletop femtosecond lasers. The innovation could make advanced laser technologies far smaller, cheaper, and more accessible for applications ranging from medical diagnostics to atomic clocks. - Share: For decades, ultrafast lasers...
Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks Stephanie Baum Scientific Editor Robert Egan Associate Editor Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel Prize-winning technology behind today's most precise optical atomic clocks. Yet despite more than two decades...
Ancient DNA reveals how women helped transform prehistoric Europe
Ancient DNA reveals how women helped transform prehistoric Europe Ancient DNA reveals a surprisingly dynamic Europe, where marriage, migration, and cultural exchange reshaped populations long before recorded history. - Date: - May 30, 2026 - Source: - The Conversation - Summary: - New DNA evidence shows that Europe’s hunter-gatherers and early farmers interacted far more closely than previously thought, with women likely playing a crucial role in spreading farming across northwestern Europe....

Decades of Effort Restore Steelhead and Salmon Passage on Alameda Creek
Last year, California Trout and Pacific Gas & Electric removed the final barrier to fish passage on California’s Alameda Creek with funding from NOAA Fisheries’ Office of Habitat Conservation. For the first time in 50 years, threatened Central California Coast steelhead and other migratory fish can reach spawning grounds and juvenile rearing habitat in the upper watershed. Construction crews relocated a Pacific Gas & Electric (PG&E) natural gas pipeline and removed its concrete covering.
