Hydrogen masers reveal new secrets of a massive star
While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's gas disk at impossibly high speeds. What's more, they believe the jet is caused by strong magnetic forces surrounding the star.
Scientists find pair of black holes dining together in nearby galaxy merger
While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA)—an international observatory co-operated by the U.S. National Science Foundation's National Radio Astronomy Observatory (NRAO)—scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy.
Astronomers find the most distant stars in our galaxy halfway to Andromeda
Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way's stellar halo. The most distant of these stars is more than a million light years from Earth, almost half the distance to our neighboring galaxy, Andromeda, which is about 2.5 million light years away.

NASA space missions pinpoint sources of carbon dioxide emissions on Earth
A case study involving Europe's largest coal-fired power plant shows space-based observations can be used to track carbon dioxide emissions—and reductions—at the source.
Want natural food dye? Amaranth delivers, according to study
Artificial food dyes have been linked to multiple health concerns, including hyperactivity in children, allergies, and certain cancers. The science isn't settled and the Food and Drug Administration says color additives are safe, but consumers are nonetheless clamoring for natural alternatives.
Two studies identify new strategies for insect control
Mosquitoes spread several diseases, among them malaria and dengue virus. In 2020, about 241 million cases of malaria occurred worldwide, with a few more million cases occurring in 2021. Nearly half the world's population lives in regions where contracting dengue virus is a risk. Insects also destroy a third of agriculture.

How the 'Kimchi premium' on crypto affects overseas remittances
The "Kimchi premium" is a term used to refer to the gap between the price of bitcoins in South Korean versus Western exchanges. This difference, which was first observed in 2016, is caused due to the high demand for a limited supply of bitcoins. The Kimchi premium is not constant, but when it appears, bitcoins can be as much as 50% more expensive in South Korea.
