Science worth understanding.
Research, evidence, engineering
We read the research, examine what the evidence can support, and explain why it matters. Clear claims, visible sources and room for uncertainty.
Researchers report experimental and computational evidence that chlorine contributes to charging in a lithium iron chloride cathode, while structural changes and limited reversibility keep the finding at the materials research stage.
A review of decades of records reports record eastern Pacific leatherback nesting in Ecuador in 2025–26, with activity tied to cooler La Niña periods and hatch rates comparable to northern sites.
A 65-year Gatineau Park maple-leaf record suggests Cold War bomb-test radiocarbon lingered locally until 2024, while stored carbon delayed and slightly shifted the leaves’ atmospheric signal.
NASA’s AMPERE Challenge invites eligible U.S. companies to demonstrate 3–7 kW Hall-effect thruster prototypes, with prizes and access to NASA testing intended to advance electric propulsion for future missions.
Four volunteers completed NASA’s 378-day simulated Mars mission, gathering health and performance data that researchers will assess to inform future exploration planning.
A Caltech robot assembled an initial truss section in orbit, an early proof of robotic space construction, though technical and scheduling problems kept it from completing the planned 1.4-meter reflector antenna.
A reported study finds that gooier marine snow resists bacterial breakdown, and estimates that its stickiest particles can carry more than six times as much carbon to deep ocean waters.
