🔥 At conferences, who asks the questions shapes who gets seen. Across 24 ID&CM meetings, women were 55% of delegates but asked 36% of questions.
💬 When women moderate or speak first, others follow.

TEs aren’t just genomic parasites, they’re also engines of genomic novelty.

Our new study with ~2,000 Z. tritici genomes shows repeated TE mobilization waves during global expansion.

I had such fun thinking, reading and writing this Tansley Review on #arbuscular #mycorrhizal #fungal mycelia. We need a more fungal-centric view to better understand not only the AM fungi, but also their many ecological roles.

Check out this new Levine-Lampson collaboration, led by the talented Hyuk-Joon Jeon.

We explored the consequences of inheriting long telomeres from dad and short telomeres from mom. Or the reciprocal. Turns out, parent-of-origin matters (in mice, at least).

Mutations within promoters and coding sequences are both involved in adaptation, but their relative contributions remain to be compared directly. Using the fungal enzyme cytosine deaminase, we examine...
