The branches of the plant tree of life become fuzzy for Andean clades! The evolution of many plant groups of the Andes remain unresolved. Here a breakdown of what happens for #Brachyotum, endemic to the Tropical side of these mountains.

Evidence of introgression amid phylogenetic conflict in #Brachyotum, a plant radiation from the Tropical #Andes New #AJB research by @evoyeyo.bsky.social, Ana Bedoya, Fabián Michelangeli, Lucas Majure, Carmen Ulloa Ulloa, & @tropicalbotany.bsky.social doi.org/10.1002/ajb2... #botany #plantscience

Above: Multiple phylogenetic trees with different topologies inferred with nuclear and plastid datasets for the Andean clade Brachyotum + allies. The different methods for the nuclear dataset include a concatenation with maximum likelihood, summary-methods (ASTRAL) and co-estimation (BEAST).
Below: Left, Brachyotum cutervoanum, a narrowly endemic species from northern Peru. Right, Chaetogastra sp., presumably and F1 hybrid between the genera Brachyotum and Chaetogastra, occurring at southern Peru.

A 20 year study on 2 NIH diversity programs in Science Advances shows they doubled undergrads' odds of getting a Ph.D. That is, before the funding for those programs and for the study itself was terminated last year: www.statnews.com/2026/06/17/n...

NIH diversity programs doubled undergraduates’ odds of getting a Ph.D., 20-year study finds

A new study found that two diversity-oriented programs supported by the NIH doubled the odds that an undergraduate would earn a Ph.D.

Many parasitic plants produce tiny seeds as light as dust: you can barely even see them. But zoom in with a powerful enough microscope, and suddenly they reveal a hidden trove of jewels. (Thanks to Renata Piwowarczyk for the photos; microscopy by Justyna Kasińska)

Recently visited the Glass Flowers at Harvard, a collection of 4,300 extraordinarily realistic glass models of plants crafted by the Blaschkas, a father and son team of sculptors That’s right, these are all made primarily of GLASS — a fact difficult to accept given how accurate & lifelike they are

An overview shot of a portion of the collection: a long window box with wooden frames filled with glass models of plants carefully arranged and labeled on white backgrounds, as though part of a 3D herbarium. From this distance, they are indistinguishable from real plants. Glass model of maple leaves, featuring blended molten glass that mimics the red hues of autumn foliageA glass model of a Columbine (Aquilegia) with parsley-like leaves and pendulous, faintly red and yellow flowers that look like swans huddled together, necks touching and wings flared out. Glass model of a Potentilla with almost ferny foliage and simple, open-faced yellow flowers with fuzzy centers.

Chilling report from Brown University. Administration advises all foreign students, staff, and faculty to postpone or reconsider (ie cancel) international travel, due to federal government's crackdown on universities. Brown also warns against *domestic travel* -since it's unclear what ICE will do.

As a curator at a natural history museum, I'm gutted to learn about the dismantling of the Institute of Museum and Library Services. If anything, we need to fund, protect and preserve museum collections and uphold institutions of scientific and cultural knowledge now more than ever.
