A Brain-Eating Amoeba Just Claimed Another Victim | WIRED
Naegleria fowleri are given miltefosine, a highly controlled experimental drug that has shown promise in treating PAM.

symptoms of Naegleria infection look flu-like at first, and later like other, more common forms of meningitis. PAM is very, very rare; since 1962, the CDC has recorded just 143 case reports—

Popular Weed Killer May Be Responsible for Global Bee Deaths - Motherboard
The chemical glyphosate is the active ingredient in Roundup, a potent herbicide sold by Monsanto, and other similar products. A new study by researchers at the University of Texas at Austin found that it destroys bees’ specialized gut bacteria, exposing them to infection by deadly bacteria.

Glyphosate is the world’s best-selling herbicide, despite its links to cancer in humans. It works by targeting an enzyme in plants and some microorganisms known as EPSPS, or 5-enolpyruvylshikimate-3-phosphate synthase. According to the study, bee gut bacteria also contains this enzyme, which helps to ward off infections and regulate overall health.

When the scientists exposed bees to the Roundup ingredient, the bees’ healthy bacteria decreased, disrupting their microbiome—a mini-ecosystem of gut microbes responsible for all manner of tasks, such as blocking pathogenic invaders and processing food.

Lectins modulate the microbiota of social amoebae | Science
Bacteria coated with lectins can be stably in mammalian cells as well as dicty - possible method for transport of bacteria inside the body?

Bacterial carriage and endosymbiosis are induced by the secreted lectin discoidin I that binds bacteria, protects them from extracellular killing, and alters their retention within amoebae. This altered handling of bacteria also occurs with bacteria coated by plant lectins and leads to DNA transfer from bacteria to amoebae. Thus, lectins alter the cellular response of D. discoideum to bacteria to establish the amoebae’s microbiome. Mammalian cells can also maintain intracellular bacteria when presented with bacteria coated with lectins, so heterologous lectins may induce endosymbiosis in animals. Our results suggest that endogenous or environmental lectins may influence microbiome homeostasis across eukaryotic phylogeny.

Hoe een autist met oorsuizen op een hachelijke roadtrip gaat om zijn leven te redden |
In het programma Dokters van Morgen gaat presentatrice Antoinette Hertsenberg naar de Eliava-kliniek in Georgië met een man die een bacteriële infectie aan zijn prostaat heeft. Daar wordt hij behandeld met bacteriofagen, een alternatieve behandeling die in Nederland niet wordt uitgevoerd of vergoed.

Recombinant Spidroins Fully Replicate Primary Mechanical Properties of Natural Spider Silk - Biomacromolecules (ACS Publications)
So they got bacteria to build silk proteins with are almost twice as long as real spider silk proteins, thus the doubled protein is now a near match in performance to true spider silk fiber (true spider silk fiber benefits from good protein design and spinner design though). They seem to think it should be possible to use the fusing method to build even longer proteins to up the strength.
