Methane emissions from the Nord Stream subsea pipeline leaks.

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.

Increasing lung screening uptake: Exploring people who smoke and their family members' concerns and recommendations regarding screening invitations.

Introduction: Challenges with designing invitation materials and accessing high risk communities are all factors in encouraging attendance at lung screening. This study focused on ways to improve participation in those potentially eligible for lung screening.

Methods: A total of 50 qualitative interviews and 4 focus groups (n=17) were undertaken with people aged 50-75 years from East Midlands, UK.

Chromosome-scale assembly of apple mint (Mentha suaveolens).

Objectives: Mint oil is used in various commercial applications world-wide. Mint oil is typically harvested from commercial clones of peppermint or spearmints. Spearmints are the product of a cross between two diploid species: Mentha longifolia (horse mint) and Mentha suaveolens (apple mint).
