Hydrogen fuel cell vehicles have long been hailed as the future of clean mobility: cars that emit nothing but water while delivering high efficiency and power density. Yet a stubborn obstacle remains. The heart of the fuel ...

It's not easy eating green. Most plants are heavily defended with chemicals to deter plant eaters. For these herbivores, getting enough to eat, while minimizing exposure to toxins, is a persistent challenge that shapes their ...

The kelp forest is ephemeral, yet foundational. Fronds of this fast-growing giant seaweed come and go with the seasons, storms and waves, supporting communities of fish, invertebrates and even mammals wherever they emerge. ...

Rising temperatures of the world's oceans threaten to accelerate the melting and splintering of glaciers—thereby potentially increasing the number of icebergs and, with it, the need to better understand more about their ...

Single-cell RNA sequencing (scRNA-seq) has revolutionized modern biology, allowing scientists to study the expression of genes from thousands of individual cells at the same time. This technique helps researchers identify ...

Rising carbon dioxide (CO2) levels are known to raise temperatures in Earth's atmosphere. But slow feedback processes, including heat storage in the ocean and changes in the carbon cycle, mean that sometimes, such temperature ...

Alexander Fleming's accidental discovery of penicillin in 1928 changed the world: Once-common bacterial infections, sometimes deadly, were treatable, and a slew of antibiotics followed. But bacteria have proven a wily adversary, ...

Frogs, toads, salamanders and other amphibians are disappearing as fast as—or faster than—any other class of animals around the world, succumbing to a variety of threats, like emerging infectious diseases. According to ...

A joint research team from POSTECH and Inha University researchers has successfully developed a novel biomaterial that overcomes the limitations of natural elastin.

As the saying goes, "You catch more flies with honey than with vinegar." But in social media commentary, vinegar seems to be the tone of choice.

Plant stem cells are crucial for the world's food supply, animal feed, and fuel production. They lay the foundation for how plants grow. Yet, much about these mysterious building blocks remains unknown. Previous analyses ...

Populations live in rapidly changing environments—droughts come and go, food sources change, human activities reshape habitats. For scientists, this raises a fundamental puzzle: How do populations maintain the genetic diversity ...
