What happens if you delete large intronic regions? In human tissue culture cells, we found many deletions that decrease growth and some that increase it. In most cases, deletion affected expression or splicing of the gene. www.cell.com/cell-reports... 1/3

In case you still thought Frontiers journals were reputable places to publish, read this. In my field there are a lot of solid non-profit and scientific society journals with appropriate standards, so why would I choose Frontiers?

Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. scim.ag/4nTQ3nq
How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.

🐭 Female mice develop male genitals when researchers modified both copies of non-coding Enh13, which controls Sox9 gene responsible for testes development in male mice. This suggests Enh13 acts as an enhancer and a silencer of Sox9, per Nature Communications study. #SciSky #MedSky 🧪
