8 James Webb Telescope Discovers Earliest Known Binary Black Hole System in Early Universe¶
The James Webb Space Telescope identified LID-1166, the oldest and closest confirmed pair of black holes in the early universe. The discovery may explain how supermassive black holes grew rapidly during cosmic infancy.

Climate Science¶
7.5 Rapid warming may trigger Atlantic circulation collapse at 2°C warming¶
Research published in Communications Earth & Environment found that warming pace, not just magnitude, determines Atlantic Meridional Overturning Circulation collapse, with rapid warming triggering it at 2°C. AMOC failure would increase atmospheric CO₂ by 47–83 ppm and cause pronounced regional temperature shifts.
- Rapid warming triggers AMOC collapse at 2°C
- AMOC failure increases CO₂ by 47–83 ppm
- Arctic cools ~7°C; Antarctic warms ~6°C from collapse
- Study led by Da Nian, Johan Rockström et al.

7 Satellite data reveal continental differences in tropical forest carbon response to climate¶
A Nature study combining terrestrial laser scanning, drone scanners, and airborne systems across tropical forests in French Guiana, Gabon, and Malaysia found continental differences in how forests respond to climate in carbon storage. The research scanned ~550 hectares and measured >200,000 individual trees to create gold-standard biomass reference datasets.
- Tropical forests show variable carbon storage by continent
- ~550 hectares scanned across three regions
- >200,000 individual trees measured
- Gold-standard datasets benchmark satellite missions

7.5 Paleontologists reconstruct ancient forests from 56 million years ago, revealing climate impacts¶
Paleontologists reconstructed 56-million-year-old forests from the Paleocene-Eocene Thermal Maximum to understand how rising CO₂ affects ecosystems. A small predatory mammal shifted its diet from flesh-eating to bone-crunching during this warming period, demonstrating that dietary flexibility and generalist species were more likely to survive environmental stress.
- PETM warming period lasted approximately 200,000 years
- Dissacus praenuntius weighed 12–20 kg (jackal/coyote-sized)
- Dental microwear analysis revealed dietary shift to harder materials
- Dietary flexibility increased survival odds during climate stress

Policy¶
7.5 White House proposal could restrict U.S. scientists from high-impact discoveries¶
A proposed White House rule would grant political appointees control over federal scientific funding decisions across multiple agencies. A Higgs boson discoverer warned the rule would cause the U.S. to cede leadership in major scientific breakthroughs requiring decades of international collaboration.
- Rule from Office of Management and Budget under review as of July 2026
- Would restrict international scientific collaboration
- Political appointees gain power to fund and defund research at any time for any reason
- Risk: U.S. loses leadership in multi-decade, multi-nation experiments
