7.5 AI Discovers Novel Chemical Pathways for CO2 Conversion to Fuel¶
Researchers at India's IISc used AI and machine learning to identify 9,389 chemical reactions for CO2 hydrogenation on copper catalysts, expanding an initial database from 152 reactions. The study revealed previously missed pathways and corrected errors, such as the wrong identified main product, potentially informing more effective catalysts for converting CO2 to fuels.
- AI identified 9,389 reactions for CO2 hydrogenation—expanded from initial 152-reaction database
- Larger network revealed methanol as main product, not formic acid predicted by smaller model
- Study uncovered unexpected hydrogen mechanisms challenging established assumptions
- Research uses machine learning and quantum mechanics simulations
- Published in Nature Communications; could inform development of improved CO2 conversion catalysts

7.5 Astronomers discover two supermassive black holes just 175 parsecs apart in early universe¶
Astronomers identified two actively feeding supermassive black holes separated by 175 parsecs in galaxy MG B2016+112 observed when the universe was 2 billion years old, marking the most compact dual AGN at this redshift.
- Two supermassive black holes 175 parsecs apart
- Observed at redshift corresponding to universe age ~2 billion years old
- Most compact dual active galactic nuclei (AGN) at this redshift

7 Ancient climate cycles drove flowering plant diversity explosion¶
Research in Nature shows Earth's two warmest periods in the past 140 million years triggered both mass extinctions and explosions in flowering plant diversity. Angiosperms created ecological niches enabling tens more species per hectare, with over a million modern insect species depending on them as pollinators or food sources.
- Angiosperm Terrestrial Revolution occurred ~100 million years ago, driving major terrestrial diversity shift
- Two warmest periods in 140 million years triggered both extinctions and flowering plant diversity explosions
- Study used 10 years of computational processing; found positive correlation between river sediment and marine diversification
- Flowering plants created ecological niches enabling tens more species per hectare than without angiosperms
- Over 1 million modern insect species depend on angiosperms as pollinators, leaf-eaters, or nectar feeders

7.5 Seventh Annual Report: Earth's Climate System Becoming Unstable, Action Urgently Needed¶
The seventh annual climate vital signs report found seven of 16 indicators hit record extremes in 2026, with carbon dioxide reaching 428 ppm (50% above pre-industrial levels). Global warming rate nearly doubled from 0.19°C/decade (1970–2010) to 0.36°C/decade (2010–2024), potentially reaching 2°C above baseline before 2050.
- 7 of 16 climate indicators hit record extremes in 2026
- CO₂ reached 428 ppm in May (50% above pre-industrial); highest in 2 million years
- Methane, nitrous oxide also set records in 2026
- Warming rate doubled: 0.19°C/decade (1970–2010) vs 0.36°C/decade (2010–2024)
- At current pace, 2°C warming could arrive before 2050; ocean warming accounts for ~56% of recent sea level rise

7.5 Scientists solve Moon's asymmetry mystery using farside samples¶
Analysis of Chang'e-6 farside lunar samples suggests uneven Earth-driven heating caused ancient magma flows creating the Moon's two dramatically different hemispheres. Findings show depleted mantle material on the farside similar to Apollo low-Ti basalts, indicating mantle composition is not substantially different despite surface and crustal contrasts.
- Earth's gravitational pull drove heat-driven circulation in ancient lunar magma ocean
- Uneven heating created contrast: near side (dark volcanic plains, KREEP-rich) vs far side (cratered highlands, thick crust)
- Chang'e-6 basalts show chemical signatures matching Apollo low-Ti basalts
- Mantle composition does not differ substantially between hemispheres despite surface differences
- Research resolves long-standing scientific debate about lunar asymmetry origins

7 Microplastics are chemically active and pose biological harm risk¶
New research shows that when large plastic pieces fragment into micro- and nanoparticles, they become chemically active and may cause biological harm, contradicting the assumption that plastic is inert.
