Good day to go to the Central Co-op here in Tacoma! This beer is made partially from Kernza, a perennial grain bred by The Land Institute.

This is the first perennial grain beer I've seen since the limited release of Long Root Ale in 2018. They also have a non-alcoholic version.

Perennial crops like Kernza have major environmental benefits. Due to their perennial habit, they also deep root systems that provide them increased tolerance to abiotic stresses like drought.

#China: Rising demand for food calls for efforts to boost #grains production & self-sufficiency to counter potential disruptions to agricultural #trade with the US, the EU & Canada. To ensure #foodsecurity, China can further develop & integrate #biotechnology, strengthen equipment support & build a diversified food system: reuters.com/world/china/chinas

(2/2) Animal products, esp. ruminant #meat and luxury commodities like #coffee & cocoa, have 100x higher extinction opportunity costs than #grains & roots. Together with #dairy, #pig & #poultry products they form the majority of per-capita consumption impacts: doi.org/10.33774/coe-2024-fl5f #beef #pork

Cambridge Open EngageQuantifying the impact of the food we eat on species extinctionsAgriculturally-driven habitat degradation and destruction is the biggest threat to global biodiversity, yet the impacts on extinctions of different types of food and where they are produced and the mitigation potential of different interventions remain poorly quantified. Here we link the LIFE biodiversity metric – a high-resolution global layer describing the marginal impact of land-use on extinctions of ~30K vertebrate species – with food consumption and production data and provenance modelling. Using an opportunity cost framing we discover that the impact of producing one kilogram of different food commodities on species extinction risks varies widely both across and within foods, in many cases by more than an order of magnitude. Despite marked differences in per-capita impacts across countries, there are consistent patterns that could be leveraged for mitigating harm to biodiversity. In particular, we find that animal products and commodities grown in the tropics are generally much more impactful than staple crops and vegetables grown elsewhere. We anticipate the approach and results outlined here could inform decision-making across many levels, from national policies to individual dietary choices.

Vortex Trapping Of Suspended Sand Grains Over Ripples
--
doi.org/10.1029/2023JF007620 <-- shared paper
--
“KEY POINTS
• Observations of vortex-trapped grains suggest delayed settling of advected grains, as well as delayed advection of grains mobilized from the bed
• Quantitative comparisons of vortex-trapped sand grains compared well with theoretical formulations by Nielsen (1992, doi.org/10.1142/1269) for a forced vortex
• Improved understanding of vortex trapping effects on sediment dynamics may decrease uncertainty in large-scale coastal model predictions..."

Illustration of the vortex core (blue arrows) distinct from the boundary shear and background turbulence (gray arrows) along the sand ripple. The black streamline indicates the freestream flow direction at this time step while the vortex is developing along the ripple slope. The double-headed arrow indicates that the free-stream velocity is oscillatory.

Three high-speed cameras and a downward-looking Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser were aimed at the test section of the rippled sand bed.
charts / figures - Vorticity and grain trajectories. (a) Freestream horizontal velocity with time steps of snapshots indicated. Instantaneous velocities are overlaid on vorticity ((b)–(g)), shown at every fourth vector, with scale vector and the brown line delineating the ripple shown. Trajectories of some vortex-trapped sediment grains are highlighted with start and end times indicated by matching triangle and square symbols in (a). Times for the semi-circular paths are indicated with circle markers. Gray circles estimate regions of highest fluid vorticity, with direction of the fluid parcels indicated by gray arrows, and quadrants of the vortex outlined.

1978 Vintage Beer Advertisement

The image is a vintage advertisement for beer, showcasing an illustration of a woman with dark hair styled in loose curls and adorned with autumnal leaves and grains. She appears to be sitting at a table or bar, holding her chin thoughtfully while gazing directly into the viewer's space.
