Five years after the COVID-19 national emergency was declared, gasoline demand, distillate demand, and jet fuel demand all remain less than pre-pandemic averages. Several factors are keeping demand, which we track as product supplied, below pre-pandemic levels. For example, increased fuel efficiency in the vehicle and aircraft fleets has offset increased travel, and demand for petroleum-based distillate fuel oil has been partially replaced by biomass-based distillate fuels.

In April 2020 (the first full month following the March 13 declaration of the COVID-19 national emergency), U.S. gasoline demand fell to 5.9 million b/d, the lowest since January 1974. In April 2025, U.S. gasoline demand averaged 8.9 million barrels per day (b/d), 52% higher than it was in April 2020 but below the April 2019 average of 9.4 million

Researchers in Germany have unveiled the Metafiber, a breakthrough device that allows ultra-precise, rapid, and compact control of light focus directly within an optical fiber. Unlike traditional systems that rely on bulky moving parts, the Metafiber uses a tiny 3D nanoprinted hologram on a dual-core fiber to steer light by adjusting power between its cores. This enables seamless, continuous focus shifts over microns with excellent beam quality.

Deep beneath southern China, JUNO has launched one of the most ambitious neutrino experiments in history. With its massive 20,000-ton liquid scintillator detector now operational, it’s poised to answer one of particle physics’ greatest mysteries: the true ordering of neutrino masses. Built over more than a decade and involving hundreds of scientists worldwide, JUNO not only promises to resolve questions about the building blocks of matter but also to open entirely new frontiers—from exploring signals of supernovae to hunting for evidence of exotic physics.
