New programmable gene editing proteins found outside of CRISPR systems

Within the last decade, scientists have adapted CRISPR systems from microbes into gene editing technology, a precise and programmable system for modifying DNA. Now, scientists at MIT's McGovern Institute and the Broad Institute ...

Astronomers explain origin of elusive ultradiffuse galaxies

As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. Several questions ...

Stellar collision triggers supernova explosion

Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were tipped off by data from ...

Compounds that give coffee its distinctive 'mouthfeel'

Coffee drinkers intuitively recognize the pleasure of swallowing a smooth, rich brew versus a watery one. Aside from added cream or sugar, the coffee itself contributes to this sensation—referred to as body or mouthfeel—but ...

Man-made chemicals could be stressing out marine mammals

Marine mammals are grappling with climate change, but now a researcher has joined FIU to study whether chemical contaminants are adding an additional layer of stress to this already tense situation.
