Identifying rice varieties for mitigating methane and nitrous oxide emissions under intermittent irrigation.

Context Or Problem: Most of the research evaluating rice varieties, a major global staple food, for greenhouse gas (GHG) mitigation has been conducted under continuous flooding. However, intermittent irrigation practices are expanding across the globe to address water shortages, which could alter emissions of methane (CH) compared to nitrous oxide (NO) for reducing overall global warming potential (GWP). To develop climate-smart rice production systems, it is critical to identify rice varieties that simultaneously reduce CH and NO emissions while maintaining crop productivity under intermittent irrigation.

Third primary SARS-CoV-2 mRNA vaccines enhance antibody responses in most patients with haematological malignancies.

SARS-CoV-2 infection, and resulting disease, COVID-19, has a high mortality amongst patients with haematological malignancies. Global vaccine rollouts have reduced hospitalisations and deaths, but vaccine efficacy in patients with haematological malignancies is known to be reduced. The UK-strategy offered a third, mRNA-based, vaccine as an extension to the primary course in these patients.

Greenhouse gas emissions from cattle dung depositions in two forage fields with contrasting biological nitrification inhibition (BNI) capacity.

Grazing-based production systems are a source of soil greenhouse gas (GHG) emissions triggered by excreta depositions. The adoption of forages (formerly known as ) with biological nitrification inhibition (BNI) capacity is a promising alternative to reduce nitrous oxide (NO) emissions from excreta patches. However, how this forage affects methane (CH) or carbon dioxide (CO) emissions from excreta patches remains unclear.
