The augmentation of resin-embedded sample blocks with magnetic resin allows remote actuation of ultrathin sections and deposition at high packing density onto silicon wafers for correlative light and electron microscopy.
Independent dating techniques have established that the H. naledi fossils are between 236 and 335 thousand years old, indicating that small-brained hominins with relatively primitive body shapes co-existed with our early ancestors in Africa.
As in humans, Drosophila hearts are able to maintain contractile performance during healthy aging, but this maintenance is associated with an increased susceptibility to progressive dysrhythmias that can lead to fibrillatory arrest.
Building on previous work (Uervirojnangkoorn et al., 2015), we demonstrate how improved methods for processing XFEL diffraction data enable the determination of structures from poorly diffracting crystals.
The conformations of the enzyme cyclophilin A that are essential for its catalytic activity are temperature dependent and exhibit diverse responses, which is consistent with a complex energy landscape.
