[6.4] World's most sensitive detector LUX-ZEPLIN fails to find dark matter particle — ABC News

The LUX-ZEPLIN detector, the world's most sensitive dark matter detector, has found no evidence of weakly interacting massive particles (WIMPs) after nine months of data collection.

This result, presented at the TeV Particle Astrophysics conference, allows researchers to rule out WIMPs above 9 gigaelectronvolts/c². Dark matter, which constitutes about 85% of the universe's mass, remains elusive, prompting continued exploration of alternative candidates.

[6.1] NASA confirms existence of planet-wide ambipolar electric field — nasa.gov

NASA's Endurance mission has confirmed the existence of the ambipolar electric field, a weak, planet-wide electric field fundamental to Earth, first hypothesized over 60 years ago.

This field, measured at 0.55 volts, drives the polar wind, facilitating atmospheric escape at Earth's poles. The findings, published in Nature, reveal the ambipolar field's role in shaping the ionosphere and may inform studies of other planetary atmospheres.
