A single-celled green alga from the sand dunes of the Negev Desert has, within just a few years, become a key model organism in modern photosynthesis research. Chlorella ohadii helps researchers better understand plants’ adaptability to extreme environmental conditions. These findings could help make crops more resilient to heat, drought, and other consequences of climate change in the future. Haim Treves, a professor of plant metabolism at RPTU, has been studying the desert alga since its discovery. His findings have now been published in the scientific journal New Phytologist.

An El Niño event has officially started, say US scientists, raising fears of extreme weather and higher temperatures.

The deep sea is a unique ‘evolutionary engine’ with one of the richest and most unexplored sources of genetic diversity on Earth, according to a major new study that has assessed its potential to transform biotechnology and DNA sequencing technologies.

In subduction zones, the sites of the world’s largest earthquakes, tectonic activity may generate a “pump” that transports long-buried subseafloor microbes back toward the seafloor, according to research presented at the 2026 SSA Annual Meeting.

The foundational research discovers a new class of fungal ice nucleating proteins with bacterial ancestry.

Tardigrades (water bears) have often appeared in my writing as an example of remarkable resilience under extreme conditions. Our shared history goes back to the German edition of Life on the Edge, which came out in 1997, and from there they spread into the pages of Astrobiology. I just noticed I even created a tag for them back in the 00s when they took up space travel. Since then, they even landed on the Moon. Surprisingly, however, I haven't had a full feature dedicated to them. As there have been several new developments in the field of tardigrade evolution, ecology and resilience accumulating in the last few months, and as I often use the first feature of the new year to describe "fantastic species", I felt the time had come to put the spotlight on tardigrades. In the process, I learned that apart from individual specimens surviving the most horrendous physical conditions one can imagine, their lineage has also survived the last three of the five big mass extinctions. Hence it isn't even a an exaggeration to call the feature: **Ultimate survivors** Current Biology Volume 35, Issue 1, 6 January 2025, Pages R1-R3 FREE access to full text and PDF download (will become open access one year after publication) See also my Mastodon thread where I highlighted all CB features of 2025. The thread for 2024 is here . Much about the distribution, ecology and physiology of tardigrades remains to be explored. (Photo: Frank Fox/Wikimedia Commons (CC BY-SA 3.0 DE).) Update 7.4.2025: A tardigrade has just been voted Invertebrate of the Year!

Notes on the back of an envelope

Chinese researchers have recently challenged the long-held belief that "all life depends on sunlight." In a study published in Science Advances, the researchers identified how microbes in deep subsurface areas can derive energy from chemical reactions driven by crustal faulting, offering critical insights into life deep below Earth's surface.
