Hello everybody! In continuation of the Frozen Fossils and Frozen Fossils II topics this report covers fossil hunting in real winter, with excavating fossils from under the snow (@JamieLynn might be interested). The trips took place this week when we had a thaw with temperatures raising to +1-2 Celsius after a long period of frost (so that digging became possible). This time I visited the same site as in FF2, which is MUCH poorer than the one covered in FF1, but MIGHT yield more diverse fossils (which was unfortunately not the case).
New experiment using frozen mammoth cell nuclei causes some cellular activity but fails to result in cell division. Not as exciting as it first sounds since cell activity might be from the mouse egg cell used in the experiment, but at least someone is trying. https://phys.org/news/2019-03-mammoth-frozen-cells-life.html
