It's been a long time since a new jazz club has opened in Montreal. Cabaret Jazz l'Entracte on Sainte Catherine Street downtown is a non-profit, and thanks to Kevin Dean and McGill University, the 80-seat club has a piano and an organ! I'm looking forward to visiting! #jazz #live #music #Montreal #McGillUniversity https://www.entractejazz.org

It's really hard to take McGill University's austerity talk seriously when they're dumping millions of dollars on union-busting law firms, anti-labor consultancy firms, and private police to intimidate its students.

Widespread Seismic Tremor in Greenland’s Fjords
S32B-08 17Dec, 356 CC 11:40-11:50
(with Yajing Liu & @natalyagomez)Water (and heat) transport through Greenland's glacial fjords to tidewater glaciers is sparsely measured. They find seismic tremor from coastal, land-based seismometers corresponds to modelled periods of turbulent water flow and standing eddies in these fjords.

Ice Sheets Without Dynamic Topography
PP23A-03 16Dec, (214 CC) 14:35-14:45
(Natalya Gomez's group at #McGillUniversity)Dynamic topography is a deviation from isostatic equilibrium driven by mantle flow. Modelling results suggest that the choice of a dynamic topography model may be as important as the choice of climate model when simulating paleo ice sheet configurations of the last 5 million years.

Nekrodruk w natarciu. Kłujka komara tańszą alternatywą dla precyzyjnych dysz 3D
Inżynieria materiałowa wkracza na terytoria, które u wielu mogą wywołać gęsią skórkę. Naukowcy z Kanady zaprezentowali nową technikę „nekrodruku”, w której kluczowym elementem precyzyjnej drukarki 3D stała się… kłujka martwego komara. To rozwiązanie może być nawet sto razy tańsze od syntetycznych odpowiedników.
Zespół badaczy z McGill University w Montrealu, pod kierownictwem profesora Changhonga Cao, postanowił poszukać inspiracji w naturze, a dokładniej w dziedzinie zwanej nekrobotyką. Dotychczas kojarzyła się ona głównie z eksperymentami wykorzystującymi odnóża martwych pająków jako chwytaki. Kanadyjczycy poszli jednak o krok dalej, szukając idealnego narzędzia do mikrodozowania płynów.
Casting na idealną igłę
Zanim wybór padł na komara, naukowcy przeanalizowali szeroki wachlarz „naturalnych igieł”. Pod lupę trafiły żądła pszczół, os i skorpionów, kły jadowe węży oraz pazury stonóg. Większość z nich została odrzucona. Powód był prozaiczny: ewolucja przystosowała je do wstrzykiwania impulsowych dawek jadu, a nie do utrzymywania stałego, ciągłego przepływu, który jest niezbędny w druku 3D. Dodatkowo, wiele z nich było zbyt zakrzywionych.
Zwycięzcą okazała się samica komara. Jej aparat gębowy (kłujka) to prosta, wytrzymała rurka o średnicy wewnętrznej zaledwie 20–30 mikronów. Jest ona znacznie cieńsza od większości żądeł i wystarczająco sztywna, by przebić skórę ofiary – a w tym przypadku, by wytrzymać ciśnienie procesu druku.
Precyzja za grosze
Stworzona przez zespół „nekrodrukarka” wykorzystuje kłujkę pobraną od uśpionego owada, którą połączono z plastikową końcówką za pomocą żywicy utwardzanej promieniami UV. Efekty są zaskakujące. Urządzenie osiągnęło rozdzielczość druku na poziomie 18–22 mikronów. To wynik dwukrotnie lepszy od najmniejszych dostępnych na rynku metalowych końcówek dozujących.
Głównym atutem tego rozwiązania jest ekonomia. Naukowcy szacują, że organiczna dysza z komara kosztuje około 80 centów. Dla porównania, profesjonalne odpowiedniki wykonane ze szkła lub metalu są od 32 do nawet 100 razy droższe.
Natura kontra technologia
Rozwiązanie ma jednak swoje ograniczenia. Kłujki komarów, choć precyzyjne, ustępują szklanym kapilarom pod względem wytrzymałości na wysokie ciśnienie wewnętrzne. Sprawia to trudność przy drukowaniu tuszami o wysokiej lepkości, które są potrzebne do tworzenia bardziej skomplikowanych struktur przestrzennych.
Zespół profesora Cao nie składa jednak broni. Planowane jest wzmocnienie organicznych dysz powłokami ceramicznymi. W przyszłości taka technologia mogłaby znaleźć zastosowanie w drukowaniu rusztowań dla żywych komórek lub mikroskopijnych elementów elektronicznych. Zainteresowanych pogłębieniem tematu zachęcam do lektury artykułu naukowego opublikowanego na łamach Science Advances.

Mary Kang (Civil Engineering, McGill) gave us an entertaining and possibly hopeful talk (despite the topic) focused on quantifying fugitive methane emissions. One disturbing figure: their survey of inactive (non-producing wells) suggests continuing methane emissions seven times that of Canada's National Inventory Report. Hopeful in that much of these emissions are from a fraction of the total wells and therefor easier to stop.

A fascinating talk by Tricia Nadeau, USGS Hawaiian Volcano Observatory, on volcanic gas monitoring at Kīlauea:
...after an eruption with fire-fountaining, researchers need snowshoes to walk across the fresh fluffy tephra, which can be 25 meters deep close to the crater. The tephra has to be removed from the monitoring stations after each eruption.

Andrew Frederiksen (U. Manitoba) gave us a very clear explanation of a better way to analyze shear-wave splitting as a way to probe the fabric (heterogeneities) of the upper mantle under continents.
The red and orange contours of large split times in British Columbia represent aligned olivine from present-day horizontal mantle flow. Splitting in Alberta represents fabrics formed and preserved from the Precambrian.

This is in part the work of Robert Bogue, with John Stix & Peter Douglas.
Diffuse CO2 emissions can permeate to the surface and can stimulate plant growth, preceding any deformation, heat, or other warnings of an impending eruption.
