Paleobiologist Scott Lakeram analyzes 300-million-year-old coal ball fossils to reveal prehistoric plant-insect interactions ...

They are still common structures today. The fossils within consist of a series of cell-sized, presumed prokaryotic fossils. The paleontological community widely accepts these fossils as the ...

Planetary scientists in Algeria and Switzerland have developed a scientific instrument that could help hunt for signs of life ...

Scientists may finally have a way to detect ancient life on Mars by studying microbial fossils preserved in sulfate minerals.

Hungarian researchers have discovered unique bacterial communities in thermal waters that may help unravel the development of ...

Some of the tissue remains were so flawlessly fossilized that researchers could see skin cell nuclei under the ... to infer such a behavior from fossils. “I don’t see this animal spending ...

Ammonite fossils, an example is shown here, are sea creatures that became extinct about 65 million years ago. Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms ...

Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them navigate toward food sources. In multicellular organisms, growth ...

Using this approach, they have uncovered that bacteria assemble their nanoweapons in response to cell envelope damage and rapidly strike back with high precision. Some bacteria deploy tiny ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...
