Scientists have developed a chromium-molybdenum-silicon alloy that withstands extreme heat while remaining ductile and oxidation-resistant. It could replace nickel-based superalloys, which are limited to about 1,100°C. The new material might make turbines and engines significantly more efficient, marking a major step toward cleaner, more powerful energy systems.

The United States is on track to export a record amount of fuel ethanol for the second year in a row in 2025, driven by growing international demand. This growing market for exports is supporting increased U.S. fuel ethanol production, even as domestic consumption stagnates.
Fuel ethanol is a renewable fuel that is commonly blended with gasoline and is made by fermenting sugar from biomass, typically corn in the United States. The United States is the largest global producer and exporter of fuel ethanol.
U.S. fuel ethanol exports are on track to set new records
In the first seven months of 2025, U.S. fuel ethanol exports averaged 138,000 barrels per day

Under the sea, green algae have evolved a clever way to handle too much sunlight. Scientists found that a special pigment called siphonein acts like a natural sun shield, protecting the algae’s delicate photosynthetic machinery from burning out. Using advanced imaging and simulations, researchers showed how siphonein helps algae safely manage excess light energy. The discovery could inspire new solar technologies that mimic nature’s built-in protection systems.

U.S. natural gas pipeline exports to Mexico averaged 7.5 billion cubic feet per day (Bcf/d) in May 2025, the most of any month on record as Mexico’s demand for natural gas, particularly in the electric power sector, increases. On an annual basis, U.S. natural gas pipeline exports to Mexico averaged 6.4 Bcf/d in 2024, a 25% increase compared with 2019 and the highest on record in data going back as early as 1975.
Total consumption of natural gas in Mexico increased from 7.7 Bcf/d to 8.6 Bcf/d during the same time period, with most growth concentrated in Mexico’s electric power sector.
Natural gas exports from the United States enter Mexico along four main corridors—South Texas, West Texas, Arizona, and California—with a combined capacity of about 14.8 Bcf/d and an approximate utilization
