From a cut Opuntia (prickly pear) crystalline nodules sometimes appear around the central veins when healed, a bit like congealed sap. (If it oozes, it does so very slowly). I thought that might even have been the source of kefir "grains"? But I don't think there's much toxicity involved, as Opuntia is edible and even marketed as a superfood. Euphorbia sap, on the other hand, is said to be some nasty shit, avoid skin contact, etc.

Mingling funders and researchers is probably the least of JHU's ethical concerns. Besides, isn't that the business model? JHU patented that shit. -

When To Transplant Delosperma bosserabum Seedlings
fyzygy replied to Ishmael Fleishman's topic in Cacti & Succulents
Something like this would work, if it wasn't too flimsy. I think a 10cm pot is larger than you need - here's a picture of a mature $15 specimen on eBay: -
When To Transplant Delosperma bosserabum Seedlings

You can pick up used plastic pots at Bunnings and other nurseries: often the rectangular seedling punnets, and sometimes even the bulk trays they fit into, both of which I find useful for this kind of job. The important thing is not to shock them into a low-humidity environment. -

Anyone know of any organised campaigns to legalise kratom in Australia?

"We have been informed today that Dr. Ben Sessa has been summoned to appear before the General Medical Council’s (GMC) Medical Practitioners Tribunal Service (MPTS) in the UK regarding alleged misconduct. The hearing is scheduled to commence on February 29, 2024. Dr. Sessa has stepped aside from his duties with Mind Medicine Australia pending the outcome of this hearing. Mind Medicine Australia was not previously aware of these allegations or the GMC investigation" https://cpat.mindmedicineaustralia.org.au/ See also: https://awaknlifesciences.com/awakn-response-to-dr-sessas-medical-practitioner-tribunal https://www.mpts-uk.org/hearings-and-decisions/medical-practitioners-tribunals/dr-benjamin-sessa--feb-24

Sessa - Facts and Impairment - FINAL-2024-03-01T17-14-59.427Z.pdf (Thanks Pixilated, it took me a few goes with a few different browsers to decode that link). So I guess that's probably the end of his association with MMA?

In recent years the WHO and FDA both determined that Kratom was not a drug of concern. So that's encouraging. There have been copious studies on Kratom's (relative) safety since the TGA scheduled it as a poison in 2003. Not to mention, a synthetic opioid epidemic. I think it's only one of two active alkaloids, mitragynine, that's included in the poisons schedule.
