Leaf beetles' evolutionary success linked to gene transfer and symbiosis phys.org/news/2025-01-leaf-bee…

"Almost all #LeafBeetles have incorporated foreign genetic material into their genome, which is responsible for the production of #enzymes necessary to digest plant cell wall components... half of the species of leaf #beetles live in close association with symbiotic #bacteria. These #symbionts provide the beetles with important digestive enzymes, vitamins, and amino acids."

"A group of 38 scientists working in nine countries has sounded an alarm about the potential creation of mirror bacteria — synthetic organisms in which the molecular structure found in nature is reversed and could put humans, animals and plants at risk of exposure to dangerous pathogens."

@CNN reports on new research in the journal Science: flip.it/Kd5bY_

Here's the original study: science.org/doi/10.1126/scienc…

Our analysis suggests that mirror #bacteria would likely evade many #immune mechanisms mediated by chiral molecules, potentially causing lethal #infection in humans, animals, and plants.

"Conan the Bacterium" can withstand radiation that could kill a human. Scientists say they’ve found its secret weapon.

From @CNN: "A type of bacteria called Deinococcus radiodurans can withstand radiation doses 28,000 times greater than those that would kill a human being — and the secret to its success is rooted in an antioxidant."

Is the five-second rule for dropping food true? @PopularScience says: Don’t push your luck.

"The scientific research on floor food has a clear answer."

The last universal common ancestor lived off #hydrogen gas and carbon dioxide, boasted a genome as large as that of some modern #bacteria, and already had an immune system

Its genomic complexity suggests that it was one of many lineages living about 4.2 billion years ago, a turbulent time early in Earth’s history and long thought too harsh for life to flourish.

#Life evolved from a simple replicator into something resembling modern microbes very quickly.

“The medical teams in Gaza are fighting a fierce battle against bacteria, which no longer respond to most antibiotics,” said Izzedin Shaheen, a doctor in the besieged enclave, via X on 21 Nov.

“Hardly any person with a wound infection survives, no matter how hard the doctors try. All the conditions are bad – no sterilization and no sufficient antibiotics. We have even found E. Coli bacteria in bone tissue, which is unfamiliar in medical books.”

This means you can use #bacteria to determine whether someone has just been to the beach, got off the train in the city centre or taken a walk in the woods. This opens up new possibilities within #medicine, #epidemiology and #forensics.
