    From Wikipedia:

    In a 2021 study published in the journal Plant Signaling & Behavior, Felipe Yamashita and Jacob White claimed that B. trifoliata may employ a primitive form of vision to identify and mimic their hosts. This hypothesis is based upon 1905 and 1907 claims by Gottlieb Haberlandt and Francis Darwin, respectively, that some plants use ‘ocelli’ or lens-like cells to focus light onto other light sensitive cells. In this study, B. trifoliata was observed mimicking the leaf shapes of plastic plants, and researchers refined Haberlandt and Darwin’s ocelli hypothesis, claiming that B. trifoliata may be using convex shaped lenses in epidermal tissue that can detect light and “see” the shapes of nearby leaves.[24] They further proposed that, B. trifoliata processes that information through an unknown means, possibly through neuron-like structures in order to initiate mimicry.[18][23] The study also found that non-mimetic leaves have more free-end veinlets and identified the hormone auxin as a possible mediator in changes to leaf morphology.[24]

    This paper received substantial media coverage, was praised by F1000’s Faculty Opinions, and went viral on the social media platform TikTok following its release. František Baluška, a plant biologist and editor-in-chief of Plant Signaling & Behavior, praised this hypothesis, and claimed that root skototropism and photoreceptive cells in algae were analogous mechanisms for “plant sight”. However, the paper’s conclusions have largely been met with skepticism by scientists. Criticisms of the paper include poor methodology, White’s lack of a scientific background, and possible conflicts of interest between Baluška and Yamashita.[18][23] The research was awarded the 2024 Ig Nobel Prize for botany.[25]




  • So, how about the Cachy Browser from CachyOS? (aur)

    This repository benefits from the knowledge and research provided by arkenfox, their documentation was vital to this revamp, so special thanks to their project. We do not use arkenfox’s user.js but we try to keep up with it, and we also consider it a great resource for users who want to find their own setup.

    We encourage users to find their own setup and to use our default configuration as something to build on top of. This is now easier thanks to the overrides, just place your own preferences in the proper location: -> ~/.cachy/cachy.overrides.cfg

    Differences from LibreWolf:

    • Enhanced security & privacy.
    • Gentoo patches. Taken from Gentoo’s Firefox.
    • uBlock Origin added.
    • Moonlight theme added.
    • Preset for “Profile Sync Daemon” and Firejail/Firejail(hardened) available.
    • Custom Rules for uBlock Origin.
    • Custom branding.

    Notes and thanks

    Some of the older prefs in this project are taken from pyllyukko and many more were investigated on bugzilla.

    Thanks to the whole LibreWolf community.











  • I disagree. Telling the students there are three states of matter is just wrong and they have all the right to point it out. They keep that information for decades if not corrected/challenged and will give non true statements to others, their children, etc.

    What the teacher instead should have said could may be: “There are many states of matter, currently we know of (amount). The most common however are these three: solid, liquid and gas. Maybe you will encounter a fourth: plasma. The others form in very specific situations that are very outside of our everyday life. You can look them up if you want to know more. But for this class, we only focus on the three most common.”

    Everything is correct, everything is clear. The scope has been set. Teacher still looks knowlegdeable and reliable. And most importantly: does not lie, tell false facts, he provides options for individual interests and builds trust and does not offer himself for attacks on his position by misusing the trust of the students by telling them factually false content.

    Relying on groveling students is morally very bad as that’s no relationship based on trust and respect for the pupils and can easily be challenged, like in this example. You would only be offering yourself for failure and risk your “dethroning”, which is a bad foundation to build on from the beginning.

    Depending on class structure another way could be to include the students and have the whole class collect the states of matter they know of. That way the “plasma” ones could shine and get heard. That way you will probably get to the common 4 but maaaybe someone heard of the BE condensat, which would be extremely cool and impressive. Wrap it up with “Great work everyone! Actually, we currently know of (amount) different states, insane, right? For this class we will focus ourselves on…” That gives bonus points for teamplay and class strengthening.
