Efficiently Generating Mixing by Combining Differing Small Amplitude Helical Geometries
Helical geometries have been used in recent years to form cardiovascular prostheses such as stents and shunts. The helical geometry has been found to induce swirling flow, promoting in-plane mixing. This is hypothesised to...

Remobilization of dormant carbon from Siberian-Arctic permafrost during three past warming events.
Jannik Martens, Birgit Wild, Francesco Muschitiello, Matt O'Regan, Martin Jakobsson, Igor Semiletov, Oleg V Dudarev, Örjan Gustafsson
Oct 20, 2020
Carbon cycle models suggest that past warming events in the Arctic may have caused large-scale permafrost thaw and carbon remobilization, thus affecting atmospheric CO2 levels. However, observational records are sparse...
Human occupation of northern India spans the Toba super-eruption ~74,000 years ago.
