Who mapped Africa? Debunking the myth that Europeans alone plotted the continent‎

After the United Nations adopted a resolution in September 2026 endorsing a map that more fairly represents the size of Earth's landmasses, author and journalist Moky Makura of Africa No Filter—a main sponsor of the Correct the Map initiative—asked: "What else about Africa is the world underestimating that's also hidden in plain sight?"

Zombie bacteria keep building DNA after death‎

Researchers at Aarhus University have discovered that bacteria can continue producing DNA after they die. And they have found a way to control what gets produced. The discovery could eventually contribute to the development of new biological materials.

Electrical signals reveal hidden magnetic information in altermagnets for first time‎

Researchers have experimentally demonstrated, for the first time, that it is possible to obtain from an altermagnet a spin current that can transport magnetic information. This result is supported by the theoretical model of electron transport developed by the CFM group. Altermagnets are a new class of materials that, despite not exhibiting the net magnetization characteristic of conventional magnets, can generate this type of current.

Newly discovered amoeba reproduces at 145 F, breaking heat record for eukaryotic life‎

Organisms are products of the environments they live and evolve in. While the physical world is governed by universal laws like thermodynamics and gravity, there are few laws of biology. An open question for biologists like me is how environmental conditions shape what organisms look like and dictate how they live, breathe and move.

Planetary collisions may help young worlds hold on to their atmospheres‎

A new study lets some of the air out of a long-held theory that growing, rocky planets will lose their atmosphere if they smash into a large object in space.

Fresh as the microplastic-laden Sierra snow: Storms can deliver pollution to even remote locations‎

For the first time, UC Riverside scientists have measured how much microplastic pollution falls on the Sierra Nevada during snowstorms and were surprised to find significant amounts even in the most remote locations.

Light reshapes gelatin scaffolds to steer cell growth in three dimensions‎

Soft, flexible hydrogels have enabled significant advancements in engineering biological tissue by mimicking the natural scaffolding that provides structure and support to cells. Existing engineered hydrogels, however, fall short in a significant way. Unlike in nature, they do not have the dynamic ability to change their structure or support depending on what the biological tissue needs. The answer may rest in shining a light on the problem—literally, according to a team led by researchers at Yokohama National University.

Political information increasingly comes from pop culture‎

Research on political polarization points to how people's preferred news outlets and social media use create information silos, environments in which people primarily encounter views consistent with their own, further cementing those views.

Experimental study on moths supports the molecular cookie cutter idea proposed for butterflies‎

Have you ever thought about reinventing yourself? According to a new study on moths conducted by Andrei Sourakov, collection coordinator of Lepidoptera at the Florida Museum of Natural History and affiliate associate professor of entomology at the University of Florida, it's not as hard as you might think.

Is it a boy or a girl? For alligators, it may come down to one degree‎

The future of the alligator species could come down to a one- or two-degree temperature difference, according to new research from the University of Georgia. The findings are published in the Journal of Experimental Biology.
