Genome editing in the choanoflagellate Salpingoeca rosetta opens newfound possibilities to functionally probe choanoflagellate genes that may illuminate the origin of their closest relatives, the animals.
3% of >1,000 asymptomatic healthcare workers in their workplace tested positive for SARS-CoV-2, suggesting that comprehensive screening programmes are vital to prevent acquisition of COVID-19 in hospitals.
Sequential introduction of transcription factors enables large-scale generation of induced motor neurons (iMNs) from human somatic cells, and transplantation of iMNs exhibit therapeutic effects in spinal cord injury model.
Unique 'true' S-cone and S-cone bipolar cell distribution patterns in the mouse retina are previously unappreciated anatomical features that support enhanced short-wavelength signaling for color detection above horizon.
A SWI/SNF-family chromatin remodeling subcomplex from yeast is identified (RSC1) that is specialized to slide nucleosomes residing on DNA sequences that confer partial nucleosome unwrapping, with assistance from accessory factors.
