Some #bacteria use a kind of #molecular “speargun” to eliminate their rivals, injecting them with a lethal cocktail. Researchers at the University of Basel have now discovered that certain bacteria can protect themselves against these toxic attacks.

How bacteria resist hostile attacks

Pseudomonas can live peacefully in coexistence with other microbes. But when attacked by bacteria from a different species

SoMAS Study: Microplastics in Oceans Distort Carbon Cycle Understanding

Microplastics are everywhere in the oceans. These small plastic fragments come from the breakdown of larger plastic items polluting the seas.

#Jellyfish consist of approximately 1% #biological material. The rest is water. So, you could say that, evolutionarily speaking, they are perfectly tuned to hold a liquid together.

Jellyfish can be used to make mayonnaise and butter

Nature itself has created many stabilizers to maintain the structure of organisms, and over time, we humans have learned to use them in our food.

Nature-based schemes that aim to remove #CO2 through methods such as afforestation and reforestation are criticized for being temporary – the #carbon removed is often re-released once projects end – as well as fraught with risk.
#Environmental #ClimateChange #sflorg

Temporary carbon removals can compensate warming from methane emissions

Methane and carbon dioxide behave differently over time: methane warms the planet much more rapidly than carbon dioxide

FTPie moves beyond the traditional "two-pane" FTP logic by acting as a virtual file system layer for Windows. Instead of forcing you to download a file to edit it and then re-upload it, FTPie mounts these remote connections in a way that mimics local storage.

The year 2025 marks a definitive inflection point in the history of neuroscience and #geriatric medicine. For decades, the field of #dementia care was characterized by a certain fatalism—a paradigm of "diagnose and manage" where the clinician’s role was largely to document decline and support the family.
