High-resolution cryo-EM reconstructions in the presence of substantial aberrations

Here, an analysis is performed of how uncorrected antisymmetric aberrations, such as coma and trefoil, affect cryo-EM single-particle reconstruction (SPR) results, and an analytical formula quantifying information loss owing to their presence is inferred that explains why Fourier-shell coefficient-based statistics may report significantly overestimated resolution if these aberrations are not fully corrected. The analysis is validated with reference-based aberration refinement for two cryo-EM SPR data sets acquired with a 200 kV microscope in the presence of coma exceeding 40 µm, and 2.3 and 2.7 Å reconstructions for 144 and 173 kDa particles, respectively, were obtained. The results provide a description of an efficient approach for assessing information loss in cryo-EM SPR data acquired in the presence of higher order aberrations, and address inconsistent guidelines regarding the level of aberrations that is acceptable in cryo-EM SPR experiments.

The invasion of the American mink (Neovison vison) is linked to a shift in the adult sex ratio of the native European polecat (Mustela putorius) across its entire range, a new study has discovered. Through aggressive competition, the American mink has decreased the number of reproductive female European polecats. This is the first study to identify such an effect upon a native species across its entire range in Europe.

Managing physical presence across multiple blades

A method uses a firmware interface setup program for a selected compute node (“node”) to cause a firmware interface to enable a trusted platform module (TPM) on the selected node to receive a physical presence (PP) signal. The selected node is selected from a plurality of nodes within a multi-node chassis, wherein each node includes a firmware interface and a TPM. A device within the multi-node chassis is manually actuated to transmit a PP signal to each of the plurality of nodes, such that each node receives the PP signal. The PP signal is asserted to the TPM of the selected node in response to both enabling the TPM of the selected node to be able to receive the PP signal and receiving the PP signal. Still further, the method allows modification of a security setting of the selected node in response to the TPM receiving the PP signal.

Method for detecting the presence of a nucleic acid in a sample

An automated method for detecting the presence of a nucleic acid in a sample, where the method is performed within a housing of a self-contained, stand-alone analyzer. The method includes purifying the nucleic acid after it has been immobilized on a magnetically-responsive solid support. A pipette of the analyzer is used to form a reaction mixture comprising the purified nucleic acid and all reagents required to perform a nucleic acid amplification. Amplification products are synthesized that include a nucleotide sequence contained in the nucleic acid or the complement of the nucleic acid. The amplification products are exposed to a probe in a mixture, where the probe forms a hybrid with one of the amplification products. The formation of the hybrid in the mixture provides an indication of the presence of the nucleic acid in the sample.
