How pecans went from ignored trees to a holiday staple — an expert explains the 8,000-year history
Pecans are a truly American nut: They grew on George Washington’s estate, and they flew to space on an Apollo mission.

big late breaking news: the market monitor for the largest energy grid in the u.s., covering much of the midwest and mid-atlantic, has called to block new data centers connections to the grid, saying current course of growth assures regular blackouts
No more PJM data centers unless they can be reliably served: market monitor
The PJM Interconnection’s market monitor urged the Federal Energy Regulatory Commission to rule that large data centers can only come online if the grid operator can still meet reliability metrics.

Super proud of @alyssa-phillips.bsky.social 's paper, now out on biorxiv! She resolves the origin(s) of polyploid big blue-stem, a dominant species in the midwest tall-grass prairie. Her common garden analysis also informs on environmental adaptation and hints at the impacts of polyploidy.
The origins and adaptive consequences of polyploidy in a dominant prairie grass
Polyploidy is ubiquitous across North American prairies, which provide essential ecosystem services and rich soil for agriculture. Yet the mechanism driving polyploid abundance is unclear. Multiple hy...

![Fig. 3 (shortened, full legend in paper): Schematic representation of CO2 diffusion through the leaf boundary layer and into the chloroplast under different wind speeds. The cross-sections represent a leaf with a uniform boundary layer and show the diffusional path of CO2 from the ambient air to the stomatal aperture and then to the chloroplast, under two different wind conditions. The corresponding distribution of [CO2] is shown, as indicated in the key. (A) A low wind speed results in a relatively thick boundary layer where [CO2] decreases from 420 µmol mol−1 in the ambient air (
), to 350 µmol mol−1 in the air at the stomatal aperture (
), to 270 µmol mol−1 in the intercellular airspace (
