Very nice study… and surprised that I am just learning that Pontederia (Eichhornia) crassipes is an allotetraploid. Go polyploids!

We are happy to announce that the Internal Conflicts and Organismal Adaptation STN has funding available to support several small travel grants for early-career researchers to enable them to visit another laboratory.
What is this for?
This funding is intended to enable early-career researchers – PhD students, postdocs, and junior research fellows – to visit another laboratory. In so doing, they can learn a new method or approach and/or initiate novel collaborations in the form of manuscripts, grants, or fellowship proposals. We envision that these visits are short stays (a week up to a month) but longer stays are also permitted.
Who can apply?
Early-career researchers, i.e. PhD students, postdoctoral researchers, and up to junior research fellows (i.e., those in tenure-track positions but not tenured yet). Priority will be given to ESEB members and to trips that reflect novel collaborations (i.e., between people who have not previously collaborated, defined by co-authorship). ESEB membership is cheap (€40 annually, €20 for students) and discounts are available for residents of low to upper-middle economy countries (see ESEB website for details). Membership also comes with additional benefits such as reduced fees for conference attendance.
What can be requested?
Applicants can request funding to support a short research visit at another institution. The maximum amount of support that can be requested is €1.000, to be used for travel and accommodation. The provided funding cannot be used to cover research costs, wages, and/or stipends. ESEB policy states that we should minimize the environmental impact of e.g. travel; therefore, we will only support travel by airplane if the distance travelled exceeds 500 km and the travel time with alternative forms of transport would be more than 6 hours.

How to apply:
Download the application form and fill it out.

Meet Buzzdetect: An Open-Source AI Tool for Listening to Pollinators Buzzdetect uses microphones and machine learning to continuously detect pollinator activity. A new study shows how it can offer a low‑cost way to "listen" for bees in real time.

Dark blue dry beans held in my hand.

Several years ago, I managed to come up with this blue seeded variety of beans.

Since then, I've been trying to figure out how to make a blue bean with a paler color. Something like a sky-blue shade.

Three photos of a pale purplish flower, from different viewpoints, with a dissected flower (top right). It has a tubular corolla about 5 cm long and densely hairy inside. What looks like a stigma poking out (marked with a yellow arrow) is a densely glandular staminode (sterile stamen). The stigma (green arrow) has two flattened lobes, and there are four fertile stamens (blue arrow). The glandular hairs of the staminode secrete a mix of oils and fragrant chemicals that appear to have a range of possible functions mostly linked to bee pollination (see Guimares et al. 2008, doi:10.1093/aob/mcn152)

Jacaranda trees (Jacaranda mimosaefolia, Bignoniaceae) have been flowering in Nelson NZ for several weeks and I took these photos today. It's just as well I did a dissection, because what I thought was the stigma isn't. Explanation in ALT. πŸ‡³πŸ‡ΏπŸŒ± #bloomscrolling
