In the tropics & subtropics, drought-deciduous flowering trees are especially showy because they flower before the leaves emerge, i.e., they are protoanthous. Here’s Jacaranda mimosifolia. 📷: John CCBYSA2 #protoanthy #Bignoniaceae #Botany 🌾🧪🌱

Since we're celebrating Norway, well feast yourselves on Fridtjof Nansen the godfather of Arctic exploration.
Agree!!! Don't! I love the original and don't want to see a remake. Lambert, Connery, Brown all ridiculous and brilliant :0)
‘Don’t remake Highlander!’ Highlander is so perfectly awful it’s impossible to remake. It’s not so bad that it’s good. It’s so bad it’s great. There’s no way to capture the demented bombast and po-faced lunacy of the original. So don’t try. There can be only one! In @heraldscotland.bsky.social
Wow!
NASA's James Webb Space Telescope has found the strongest evidence yet for "black hole stars!" Data from a "little red dot" named GLIMPSE-17775 suggests it's a supermassive black hole enshrouded in a dense, hot cocoon of gas. 🔴✨ #JWST #Astronomy #SpaceNews 1/3

The Prime Minister of Spain: “The momentary relief cannot make us forget the chaos, the destruction, and the lives lost… The government of Spain will not applaud those who set the world on fire just because they show up with a bucket. What is needed now: diplomacy, international law and PEACE.”

This is JWST's NIRCam image of MoM-z14, the most distant galaxy detected so far. science.nasa.gov/asset/webb/c... It has a redshift of z=14.44, meaning it formed extremely early at just 280 million years after the Big Bang (13.53 Gya), and is 33.8 billion lightyears away from us.

Last week we released dplyr 1.2.0, but we left off something VERY important 🙂 `dplyr::if_else()` and `dplyr::case_when()` are now up to 30x faster and use 10x less memory! We dive into how we achieved these numbers in this new #rstats post! tidyverse.org/blog/2026/02...
`dplyr::if_else()` and `dplyr::case_when()` are up to 30x faster
dplyr 1.2.0 comes with much faster and more memory efficient `if_else()` and `case_when()` functions!

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...
dplyr 1.2.0
dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...
