Scientists reveal how first cells could have formed on Earth

Roughly 4 billion years ago, Earth was developing conditions suitable for life. Origin-of-life scientists often wonder if the type of chemistry found on the early Earth was similar to what life requires today. They know that ...

Molecular rulers for high-resolution microscopy

There is good news for researchers working with high-resolution fluorescence microscopy: Biocompatible molecular rulers are available for the first time to calibrate the latest super-resolution microscopy methods.

The underappreciated role of pods and siliques to developing seeds

Plants harness energy from sunlight and carbon dioxide through a process called photosynthesis which supports the generation of carbohydrates, proteins, and oils that are stored in seeds—like a kernel of corn, a soybean, ...
