Earlier on the expedition we found the most beautiful flower, and here, my friends, is the biggest: Rafflesia arnoldi seen in full bloom today in the Sumatran jungle. This is the largest flower on earth and one of the greatest wonders of the natural world.

J'adore ce type d'argument ! Ça marche à tous les coups et ça fait drôlement avancer le débat

I keep eating plants every day, even sometimes alive ! and from time to time, animals too (cooked in this case)

They used the paper in Cell 2023, Khait et al., to justify the evidence for suffering...
I really dislike this paper, not for the facts but for their proposed interpretation.

I replied that plants do perceive injuries but no nervous system as in animals and no evidence for similar suffering

A vegan friend needed a plant specialist a few days ago : opponents to vegan regimes claimed that plants and animals suffer the same when killed, so makes no sense to be vegan.

Des podcasts avec des anti ogm qui fait de l'anti ogm ... mais quelle surprise !

on a la sempiternelle "promesse de l'offre" d'YB qui est un grossier épouvantail, en effet sans la mutagenèse effectuée depuis 1 siècle on serait bien incapable de faire du bio

La grande chance avec les plantes mutées par les humains, c'est qu'on a un recul de 80 ans de consommation et d'usage sans danger.
Pourquoi se priver de la possibilité de faire des plantes avec un besoin réduit en pesticides????

Excited by this breakthrough work led by Dr. Lauren Stanley (now Assistant Professor at Central Michigan University). Lauren was able to develop for the first time floral dip/spray transformation methods in the yellow monkeyflower (Mimulus guttatus). bsapubs.onlinelibrary.wiley.com/doi/10.1002/...

Flowers of California poppy (Eschscholzia californica). 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.)

This weekend, a very special event will take place for me, undoubtedly the most wonderful surprise of my life as a scientist.

First post on the Node and first attempt at summarising a paper that is not about plants! 😱

Super cool paper, had fun writing my summary 📝

The buff-tip moth (Phalera bucephala) has mastered a very particular kind of camouflage.

When they close their wings up, they resemble a broken twig.

Native to large parts of Europe, there's regional pattern variation that reflects the local tree species. This one best resembles birch twigs?
