Identification of carnivory in the flowering plant Saxifraga via multidisciplinary evidence - Nature Communications
Carnivorous plants capture and digest insects for nutrients, an adaptive strategy typically found in wetlands. This study identifies carnivory in the alpine Saxifraga plant lineage, supporting Darwin'...

#Climate adaptation in #plants requires precise regulation of carbon export. This study shows that siRNA-guided methylation of a sucrose transporter gene modulates its expression with temperature, revealing a mechanism linking epigenetics to adaptive carbon transport. 🧪 #AcademicSky plos.io/4wxF4Ug

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

We started by studying gene reuse in eyes over deep time -- but were astonished to find adaptive molecular convergence to be rampant and not directly related to important traits, including eyes. Led by PD Cory Berger www.biorxiv.org/content/10.6...

A simple but (I think) compelling re-analysis of a paper that Director Bhattacharya frequently cites in his talks to claim that NIH-funded researchers no longer pick up the newest ideas. Dr. Bishop concludes the opposite using the same data. The original conclusion was contrary to my experience.

New Preprint 🥳 Here we wondered how phages that have been extensively studied in laboratory E. coli strains actually behave when they encounter a real pathogen such as O157:H7 strain...one with a far more complex cell surface & one of the most consequential foodborne pathogens in the United States.

what a great article — I had no idea about any of this. There are only 25 IMAX 70mm theaters in all of America!! They can’t make new IMAX projectors because they don’t have the plans anymore! They had to track down broken ones ahead of “The Odyssey” and fix them!! variety.com/2026/film/ne...

'The Odyssey' has spiked interest in IMAX70mm showings, but the company explains why building more is 'not practical.'

🌲 From UC Davis: Prescribed fire can help ancient forests survive a changing climate. Treated giant sequoias were far more likely to survive extreme wildfires. (Dan Dixon, Yufang Jin) ▶️ www.ucdavis.edu/climate/news... #PlantScience #California #Wildfires
Prescribed Burns Saved Thousands of Giant Sequoias
When two major wildfires burned through the Sierra Nevada in 2020 and 2021, they took thousands of giant sequoia trees with them. Without prescribed burns, thousands more would have died, according to...

I don't recall ever noticing Unicorn caterpillar moth (Coelodasys unicornis) larvae before, but it's easy to see how they got their name. Too bad these were feeding on a chestnut tree seedling I started from a local nut I picked up last fall. I sent them packing.
it changes color by filling the area with a clear liquid, and since the color is structural and not pigment, the liquid just changes the index of refraction and targets different wavelengths to bounce out! (You can do the same thing with a butterfly wing in alcohol! blue morpho wing will go green!)
