8 Earth's oceans reach highest temperature on record, potentially breaking millennia-old mark¶

The world's oceans reached unprecedented temperature highs, driven by record El Niño conditions and marine heat waves, with the record potentially being the highest in thousands of years.

7.5 Europe's 2026 summer heat wave sets temperature records across continent¶

Western Europe set temperature records during summer 2026, with the June–July average reaching 21.62°C and surpassing 2022's record. The heat drove devastating wildfires across France and the Iberian Peninsula, prolonged droughts, and over 1,300 excess deaths, underscoring Europe's position as the fastest-warming continent.

Western Europe June–July average: 21.62°C, exceeding 2022 record
Spain's Fabra Observatory recorded 40.5°C on July 8, highest in >100 years
France experienced fifth heat wave alert by mid-August
Europe warmed ~2°C in 50 years since 1976, fastest warming continent
1,300+ excess deaths recorded in Europe since mid-June
June 2026 global ocean surface temperature highest for the month, exceeding June 2024 by 0.01°C

7.5 Common medications reshape gut microbiome for years after use¶

A study of over 2,500 participants from Estonia found that common medications including antidepressants, beta-blockers, proton pump inhibitors, and benzodiazepines cause lasting changes to the gut microbiome detectable years after treatment ends. Benzodiazepines showed microbiome alterations comparable to broad-spectrum antibiotics.

7.5 Stellar Stream Reveals Dark Matter Distribution in Distant Galaxy¶

Astronomers identified the first globular cluster stellar stream outside the Milky Way, a faint ribbon of stars around a distant galaxy created over billions of years as an ancient cluster dispersed. By analyzing the stream's shape, researchers reconstructed the galaxy's gravitational field and estimated dark matter distribution.

7 Engineered Yeasts Convert Plastic Waste and Crop Residue Into Edible Protein¶

Researchers at Southern Illinois University Carbondale have engineered yeasts to convert plastic waste and agricultural residue into edible proteins and food ingredients, creating a product called µBites. Developed with NASA support for food production in extreme environments, the technology uses hydrothermal dissolution to break down PET plastic and plant biomass, then deploys modified yeast strains to metabolize the resulting compounds.

µBites: protein-rich cookie from waste carbon and yeast-derived ingredients
Engineered yeast strains: Saccharomyces cerevisiae, S. boulardii, Rhodosporidium toruloides
Feedstocks: PET plastic bottles and agricultural biomass like corn stalks
Applications: disaster zones, submarines, deep space missions
Presented at ACS Fall 2026 meeting, August 24, 2026
