The source gives the direction and rough size of the wobble but no exact figure, no method detail and no stated uncertainty. https://science.briefpulse.com/stories/science-fungi-carried-bark-beetles-can https://science.briefpulse.com/stories/science-fungi-carried-bark-beetles-can 2026-09-16T21:06:57+00:00 BriefPulse Science A Max Planck Institute for Chemical Ecology team says certain fungi — delivered into trees by bark beetles — neutralize spruce defense compounds, which the source says makes beetle invasion easier. The announcement supplies no sample sizes, controls, fungal species names or published study detail, so the finding's reach is untested in what we have. https://science.briefpulse.com/stories/science-neutrino-laser-impossible-due-physical https://science.briefpulse.com/stories/science-neutrino-laser-impossible-due-physical 2026-09-16T20:51:03+00:00 BriefPulse Science MIT News reports that an earlier proposal for a neutrino laser cannot be achieved because of physical and fundamental limitations, according to scientists. The announcement provides no details on the analysis, so the certainty of the claim remains unclear. https://science.briefpulse.com/stories/science-chariklo-two-rings-changed-opacity https://science.briefpulse.com/stories/science-chariklo-two-rings-changed-opacity 2026-09-16T19:39:01+00:00 BriefPulse Science The James Webb Space Telescope saw the inner ring of Chariklo, a small object orbiting between Saturn and Uranus, become more opaque while its outer ring became less opaque over just a few years. The report names no cause and gives no measurement figures, so the size and certainty of the change cannot yet be checked. https://science.briefpulse.com/stories/science-simulations-suggest-venusian-moon-would https://science.briefpulse.com/stories/science-simulations-suggest-venusian-moon-would 2026-09-16T19:13:59+00:00 BriefPulse Science New computer simulations suggest Venus may once have had a moon that spiralled inward and hit the planet instead of drifting away like Earth's. The claim rests on modelling alone, and the material available here does not identify the researchers, the journal or the peer-review status of the work. https://science.briefpulse.com/stories/science-model-explains-track-cyclists-seem https://science.briefpulse.com/stories/science-model-explains-track-cyclists-seem 2026-09-16T19:03:09+00:00 BriefPulse Science Some track cyclists look as though they begin a race already moving, in apparent violation of physics. A modelling study in Royal Society Open Science offers an explanation of the illusion, rather than a demonstration that any rule was broken. https://science.briefpulse.com/stories/science-nasa-reports-seasonal-water-shifts https://science.briefpulse.com/stories/science-nasa-reports-seasonal-water-shifts 2026-09-16T19:03:02+00:00 BriefPulse Science NASA reports that seasonal water redistribution shifts Earth’s center of mass back and forth by fractions of an inch relative to its geometric center.
