Stanford, CA, USA. Scientists have adapted mass cytometry, already in use for the measurement of impurities in semiconductors, and used it to analyze immune cells in far more detail than has been possible before.

The investigators were able to simultaneously categorize more immune cell types than ever before seen at once while at the same time peering inside those same cells and learn how various internal processes differed from one cell type to the next.

Berkeley, CA, USA. The search for the time, place, and circumstances of our arrival as Homo sapiens is one of the most important intellectual challenges we face, with answers that have important practical implications for our continuing survival.

But first, the science. We know our own species and can distinguish ourselves from others. How do we know that? Mason Liang and Rasmus Nielsen from UC Berkeley answer some questions on how we know what we know so far, while identifying the research tas
