Phys.org / Yeast survives after all 300 known spliceosomal introns are removed

Spliceosomal introns are noncoding DNA sequences located between exons in many eukaryotic protein-coding genes. Most are removed post-transcriptionally by RNA splicing and do not encode proteins, but they have been implicated ...

Phys.org / How insect submariners survive the depths without imploding

Deep-diving insect larvae are challenging a long-held idea about why there are almost no insects in the ocean, thanks to sturdy air sacs. In Lake Malawi in East Africa, billions of lake fly larvae (Chaoborus edulis) make ...
