Nature Magazine, May 19, 2022 – At industrial scales, chemical reactions are typically driven by applying continuous heat to the reactants. In this week’s issue, Liangbing Hu and his colleagues show that pulsed heating and quenching can enhance synthetic performance while also saving energy.
The researchers use a programmable electric current to switch between high and low temperatures very quickly — typically 0.02 seconds on, 1.08 seconds off. Rapidly quenching the reaction gives high selectivity, maintains catalyst stability and reduces energy usage. The cover image illustrates the heater in action for the pyrolysis of methane — the model reaction the team tested. Methane molecules travel through the pores of the high-temperature heater and are selectively converted into useful products.
Aerial Views: Punta Cana, Dominican Republic (4K)
Punta Cana, the easternmost tip of the Dominican Republic, abuts the Caribbean Sea and the Atlantic Ocean. It’s a region known for its 32km stretch of beaches and clear waters. The Bávaro area and Punta Cana combine to form what’s known as La Costa del Coco, or the Coconut Coast, an area of lavish, all-inclusive resorts. It’s popular for zip-lining, windsurfing, kayaking and sailing.
Morning News: North Korea Covid Surge, Turkey Voters, Arab School Girls
North Korea’s zero-covid strategy appears to have failed. The country has officially acknowledged 162 cases; the true number is probably orders of magnitude more.
The country’s health-care system is inadequate, and pre-existing conditions such as tuberculosis and malnutrition are rampant. With elections impending in Turkey, politicians have begun competing with each other to scapegoat refugees. And why girls outperform boys in the Arab world’s schools.

COVER STORIES
Science: Galaxies Without Dark Matter, High Helium Levels, Solar Energy Jump
Dark matter makes up most of the matter in the Universe, and is thought to be needed for galaxies to form. But four years ago, astronomers made a perplexing, and controversial discovery: two galaxies seemingly devoid of dark matter.
This week the team suggests that a cosmic collision may explain how these, and a string of other dark-matter-free galaxies, could have formed.
