📡🧵 Excited to release two #bioRxiv preprints! The first preprint is: "Zebrahub-Multiome: Uncovering Gene Regulatory Network Dynamics During Zebrafish Embryogenesis" We present a comprehensive time-resolved single-cell multiomic atlas of zebrafish development. Integrating scATAC-seq and scRNA-seq from 94,000+ cells, we map gene regulatory networks across six key stages of embryogenesis (10 to 24 hpf). A major accomplishment by YangJoon Kim co-led by Merlin Lange with experiments by Shruthi VijayKumar #Zebrahub-Multiome is a sequel to our transcriptomic and imaging atlas of zebrafish development. #zebrafish #development #ATACseq #cell #biology #sequencing Chan Zuckerberg Biohub Network #CZBiohubSF Biohub Note: We sent two preprints simultaneously yesterday, and this is the first one to come out... I will append to this thread when the second one is out...

Venom is metabolically expensive to produce (proteins, enzymes, peptides). It takes days to weeks to fully replenish venom glands after a big envenomation. When biting defensively, the snake often just wants you to go away, not to kill and eat you. A quick warning bite without venom is often sufficient and saves the snake its precious venom for actual prey. One thing we must know is that venom delivery is not automatic. The compressor muscles around the venom glands must contract to force venom through the fangs. The snake can choose: 1. No contraction → dry bite 2. Brief/light contraction → small dose 3. Full contraction → maximum envenomation Therefore, the snake can decide whether the animal it wants to bite deserves the venom or not, and how much venom it deserves. Note: Treat any snake bite from a venomous animal as wet bite. It's better to err on the side of caution. Tainkyu
