Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.
With decades of images and data from the same locations, these satellites can show changes over time, including deforestation, changes in waterways and how loss of trees corresponds to urban heat.

Megalodon, the world’s largest known shark species, swam the oceans long before humans existed. Its teeth are all that’s left, and they tell a story of an apex predator that vanished.
The story behind the research can be as compelling as the results. Recording the effects of starvation, a group of Jewish doctors demonstrated their dedication to science – and their own humanity.
The protective caps at the ends of chromosomes naturally shorten over time. Researchers found that direct damage can prematurely trigger senescence and contribute to age-related diseases like cancer.

Crowdfunding has become a go-to means of raising money for political causes, but the monetary show of support can cause opponents to double down on their opposition.
Life on Earth has dramatically changed the chemistry of the planet. Astronomers will measure light that bounces off distant planets to look for similar clues that they host life.
The idea that Europeans brought new diseases to the Americas and returned home with others has been widely accepted. But evidence is mounting that for syphilis this scenario is wrong.
Scientific research done through international collaboration has boomed in the past 30 years. But recently, powerful countries are using science as a tool of politics, threatening that work.
Patients with blood cancer undergoing stem cell transplantation have a high risk of complications. The bacteria in their gut, however, can help their immune system recover and fight infections.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.
