🧬🔬 Why are enhancers transcribed and how does that impact gene regulation? I’m really excited to share our new paper in @science.org showing that noncoding RNAs control the timing of gene activation in embryos. With Mike Levine #ScienceResearch @columbiamed.bsky.social A few highlights below... 🧵👇

Noncoding transcription controls the developmental dynamics of long-range gene regulation
The genomic regions regulating gene expression are often themselves transcribed into a variety of noncoding RNAs (ncRNAs). However, the regulatory roles of this noncoding transcription remain largely ...

The 2025 "My favourite flowering image". The brightest orange: California poppy (Eschscholzia californica) flowers as windows into evolutionary developmental genetics. Two fused sepals form a hat-like structure that has already dehisced, while four free bright orange petals adorn the blossom. Inside the flower, though not visible from this perspective, are numerous stamens arranged in several whorls and a gynoecium composed of two carpels. The gynoecium is surrounded by a floral cup forming a wide rim, which can be seen on the lower left, once all other organs have fallen off. (Image credit: Annette Becker.)

80% of agricultural land is used for livestock (and textiles), yet this huge land use provides only 17% of our calories and 38% of our protein. 16% of the land used for crops provides 83% of our calories and 62% of our protein. It's past time we rethink what we eat.
An infographic from Our World in Data titled "Global land use for food production" uses a series of stacked horizontal bar charts to visualize the distribution of Earth's surface and the disproportionate land requirements of livestock. The first bar shows Earth's surface is 71% ocean and 29% land (141 million km²); the land surface is then broken down into 76% habitable land, 10% glaciers, and 14% barren land. Of the habitable land, 45% (48 million km²) is used for agriculture, while 38% is forests and 13% is shrubland. The agricultural land bar reveals a major disparity: 80% (38 million km²) is dedicated to livestock (meat, dairy, and textiles) including grazing land and cropland for feed, while only 16% is used for crops for direct human consumption and 4% for non-food crops. Finally, two smaller bars at the bottom contrast this land use with nutritional output, showing that while livestock uses 80% of agricultural land, it only provides 17% of global calories and 38% of global protein, whereas plant-based foods provide 83% of calories and 62% of protein.
