Technology, international bonds, and inspiration: Why astronomy matters in times of crisis
In an international emergency like the present one, you might expect the science of the stars to be the last thing on people's minds. The problems facing both individuals and governments are infinitely more pressing than events in the depths of space. People are suffering unprecedented hardships.

The Countries Taking Advantage of Antarctica During the Pandemic
A ntarctica may be the only continent that hasn't been physically hit by the pandemic, but that doesn't mean it has been immune to its aftershocks. As the outbreak ripped across the globe, forcing governments to provide bailout programs for their citizens, countries began to stall their Antarctic programs, not least as a safeguard to prevent the coronavirus from engulfing the continent.

Genotoxic stress triggers the activation of IRE1α-dependent RNA decay to modulate the DNA damage response
Nature Communications, Published online: 14 May 2020; doi:10.1038/s41467-020-15694-y IRE1α plays a key role in the unfolded protein response (UPR) by promoting the unconventional splicing of the XBP1 and the selective cleavage of RNAs. Here the authors report that IRE1α is activated upon the DNA damage response and selectively controls the stability of mRNAs to maintain genome integrity.

Tenofovir prodrugs potently inhibit Epstein-Barr virus lytic DNA replication by targeting the viral DNA polymerase [Microbiology]
Epstein–Barr virus (EBV) is a ubiquitous human γ-herpesvirus that establishes life-long infection and increases the risk for the development of several cancers and autoimmune diseases. The mechanisms by which chronic EBV infection leads to subsequent disease remain incompletely understood. Lytic reactivation plays a central role in the development of EBV-driven…

Genomic evidence for convergent evolution of gene clusters for momilactone biosynthesis in land plants [Plant Biology]
Momilactones are bioactive diterpenoids that contribute to plant defense against pathogens and allelopathic interactions between plants. Both cultivated and wild grass species of Oryza and Echinochloa crus-galli (barnyard grass) produce momilactones using a biosynthetic gene cluster (BGC) in their genomes. The bryophyte Calohypnum plumiforme (formerly Hypnum plumaeforme) also produces momilactones
