A newly discovered bacterium, Uabimicrobium helgolandensis, eats other bacteria and is a kind of 'bacteria of prey,' that should not even exist based on previous concepts about microbial cells. It could be a kind of microbial missing link, researchers suggest.

Mesmerising microbes: bacteria as you’ve never seen it before – in pictures
“As a side hustle he manipulates and photographs the microbial world; his images are collected in a book, Beautiful Bacteria. Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative.”

Upper Cretaceous. Approximately 100.5 million to 66 million years ago. When alive, this creature lived in warm, shallow seas and had a very short tail, which was fitted with a venomous stinger. Discovered in Haqil, Byblos, Lebanon. It just happens to look like an ancient space alien. #science #fossil #archeology #evolution #photo #nature #biology #wildlife

I just finished putting together a Wikipedia article on plant biologist Mary Clutter, who was so instrumental in determining mechanisms for gene regulation and expression through her work with plant hormones.
She also was one of the foremost scientists involved in expanding opportunities for women scientists in the latter half of the 20th century, including getting them the recognition they deserved for their accomplishments.
Scientists and the general public have long dismissed the cognitive abilities of cows, pigs, and other livestock. But farm animals are capable of much more than we think.

Marine #microorganisms are crucial for #ocean health.
#Bacteria, #archaea, #fungi, #algae and #viruses make up most of the biomass in the seas and form the base of marine food webs.
They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles.
Ocean modelling must evolve to take their biological complexity into account.

While we are still trying to find ways to clean up problems like oil spills in the ocean, microorganisms in the seas have their own insights to impart.
Oil rich soil from the Guaymas Basin has provided German scientists understanding of a mechanism by which archaea in the Alkanophaga break down alkane molecules and thus degrade petroleum through oxidation.
