An interaction between the brown fat protein CIDEA and the phospholipid phosphatidic acid is vital for the expansion of intracellular lipid droplets for energy storage.
In parallel to protein-driven processes, characteristic physicochemical properties of the endoplasmic reticulum membrane modulate intracellular fat accumulation and lipid droplet formation.
This microscale cultivation strategy will help in the discovery of novel bacterial species and their prioritization for antibiotic screening campaigns.

High-throughput droplet-based cultivation of gut microbes reduces biases of traditional cultivation strategies and thereby enables detection of difficult-to-culture organisms, which is required in applications such as antibiotic screening.
Seipin oligomers dynamically interact with small, nascent lipid droplets near the endoplasmic reticulum to convert them into larger, mature lipid droplets in a newly identified step of lipid droplet formation.
New open-source method contains all the tools for extracting open chromatin or RNA from thousands of single cells in parallel for <5% of the cost of state-of-the-art commercial alternatives, paving the way for whole-tissue atlasing and new protocol development.
Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.
Broader case variation in respiratory viral load, and in shedding virus via droplets and aerosols, for SARS-CoV-2 than influenza A(H1N1)pdm09 facilitates greater transmission heterogeneity in the COVID-19 pandemic than the 2009 flu pandemic.

The targeting of proteins from the endoplasmic reticulum to lipid droplets relies on surface modulation of the lipid droplet by the Arf1/COPI machinery.
