Abstract Tick bites in Australia are associated with a poorly understood syndrome known as Debilitating Symptom Complexes Attributed to Ticks (DSCATT), however, the underlying biological mechanisms remain unclear. Here, we investigate host responses to tick bite and DSCATT by profiling circulating host-encoded microRNAs (miRNAs), key regulators of gene expression.

Abstract The protease TMPRSS2 facilitates coronavirus infections, yet its mechanism of viral glycoprotein recognition remains unclear. Here we show that, following ACE2 engagement of the SARS-CoV-2 spike (S) inducing the early fusion intermediate conformation (E-FIC), TMPRSS2 cleaves the R815 S2′ site and promotes fusogenic conformational changes leading to viral entry.

Government pledges up to $7bn for Aussie counter-drone defences

|

By Cameron Stewart, chief international correspondent, The Australian The Albanese government says it will invest up to $7 billion in counter-drones in the next decade as it seeks to plug a key weakness in the capability of the Australian Defence Force. The commitment reflects a growing if belated recognition by the government of the critical function of counter-drones in modern warfare, as shown by the central role they have played in conflicts in Ukraine and the Middle East.
