To peer back in time at certain key steps of evolution, scientists at the Scripps Research Institute have engineered synthetic microorganisms designed to be similar to some that might have lived billions of years ago.

Researchers from ETH Zurich have found a way to make use of some of the chemical weapons bacteria have developed against each other. In this case, that bacterial battleground is on the surface of thale cress leaves.

Two worms frozen in the Siberian permafrost for around 40,000 years have now been thawed and revived, making them the oldest living creatures on the planet and the first multicellular organisms to have survived such long-term cryobiosis.

Scientists have uncovered what they’re calling the oldest colors on Earth. Dating back more than a billion years, the bright pink pigments are the remains of some of the earliest microscopic organisms that once inhabited an ancient ocean, and their discovery helps fill a gap in the fossil record.

Living cells follow instructions encoded in DNA to construct organisms. It’s long been thought that one DNA sequence would always create the same protein, but now researchers have found the first exception to this “universal rule,” a microbe that chooses between two different translations each time.

With microplastics now in the deepest ocean trenches and moving up the food chain, it’s no surprise that plastic pollution is in the crosshairs for Earth Day 2018. IBM has now released a video outlining how it's helping clean up the seas, using plankton as a kind of living water quality sensor.

The human brain is a beast of a computer, but before we can emulate that we’ll need to start with something simpler. C. elegans is a worm whose basic brain of only 302 neurons has been digitized. Now researchers have taught this virtual worm a new trick, without writing a single line of code.

Microscopic fossils found in Australia decades ago appeared to show evidence of life dating back almost 3.5 billion years, but have since been contested. New analysis shows that the microfossils are indeed biological, and the find may have implications for the likelihood of extraterrestrial life.

No matter how useful a certain human innovation is, nature has usually beaten us to it by millions of years and done a better job. A Yale team has looked to nature to help solve a design problem, using tiny fossilized creatures called diatoms to improve the light absorption of organic solar cells.

As far as most laypeople know, all amoebas are soft-bodied creatures. In fact, though, amoebas of the Thecamoeba genus have a hard outer carapace. In the case of a recently-described new species of Thecamoeba, that shell resembles the wizard's hat worn by Gandalf in The Lord of the Rings.
