Bad behaviour in the workplace

Half of the people studying or working at Swedish universities said that their contributions or opinions had been ignored, according to the largest-ever nationwide survey of academic workplace culture. The results, which included responses from people at all of Sweden’s 38 higher-education institutions, examined the prevalence of bullying and how often respondents had experienced types of microaggression — such as being spoken over, ignored or shouted at. The concern is that such behaviours, if left unchecked, can lead to a working environment in which bullying and harassment are tolerated.

COVID vaccine mandates

These graphs show the results of COVID-19 vaccine mandates in France and Germany. Requiring people to be vaccinated is controversial, as our Feature reports, but emerging data suggest that in countries where mandates have been introduced during the pandemic, they have increased vaccine uptake and reduced hospitalizations and deaths.

Classifying neurons

Researchers have attempted to create a catalogue of brain-cell types — an essential step towards understanding how the brain works. Writing in Nature, the authors used a technique called calcium imaging to record the activity of large populations of neurons as mice ran on a ball and responded to visual stimuli on a screen. The team then used a technique called coppaFISH to analyse the expression of 72 genes in slices of brain containing the same neurons. The authors mapped the coppaFISH profile of each neuron onto existing gene-expression profiles (transcriptome data) for neurons of various identities. This enabled them to assign each of the neurons that they had analysed to one of several subclasses, types and subtypes. They found that the responses of the neurons to various features of visual stimuli (such as orientation) differed across subclasses, whereas responses to different brain states, such as whether a mouse was running or still, were apparent at subclass, type and subtype levels.
