In this episode we hear about using photographs to diagnose rare genetic disorders, an unexpected benefit of exercise, hybridizing fish species, Rett syndrome, and using gene drives to eradicate disease.
Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
Establishing retinal contrast transmission as a novel determinant of mammalian fitness, this research adds functional significance to a prominent exception of nuclear organization, previously described in nocturnal rod photoreceptor cells.
Bats' uniquely robust innate antiviral immune defenses select for faster transmitting viruses likely to generate extreme virulence upon spillover to secondary hosts with immune systems divergent from those of bat.
Biochemical, single molecule, cell and structural biology studies reveal an interaction between the kinesin-5 tail and motor domains regulating high-force production, which is critical for microtubule sliding motility.
