Does glass flow? No. This common myth spins off from the similarity of glass with liquids. However, once cooled, most glasses are a species of their own. Since they lack a regular structure, they are not similar to crystals. The term for this is amorphous.
Glass makers did not have the technique to make constant-thickness glass till the modern age. Furthermore, it would have been slightly advantageous to make a glass plate thicker at the bottom to create stability.
The argument against the cooled flowing glass theorem, formulated by an early chemist, lies with century old Roman glass in burial tombs and antique telescopes, both which should have shown signs of degradation.
Why plastic-eating fungi won’t save our wasteful habits
A few months ago lots of news websites, both legit and sensationalist boomed with the seemingly incredible study that a certain fungi class, mainly hailing from the Amazon jungle, slowly degrade polyurethane (PUR) to simpler chemicals like acetates and CO2.
Why this won’t work to solve the landfill porblem we have? Many reasons:
- adapting a microorganism to work in any environment, including one filled with a toxic atmosphere and dry conditions may proove troublesome
- this may unbalance ecosystems more, adding to the damage
- ridiculous idea to implement on a large scale - how exactly are we going to get feedback?
- not that many plastics are PUR. The main use is in insulating foam. Your bottles are PET, clothes are polyesters (PS), industry use polypropylene (PP)…
- alternative treatments, such as subjection to intense UV bursts and microwaves show more promise for rapid degradation
According to various pharmacological studies, St. John’s Wort(hypericum perforatum) is useful in treating patients with mild depression. Problem is, the exact mechanism of how it works is not fully understood.
The complex flavonoids hyperforin and hypericin are difficult to reproduce industrially, and the plant seems to have none of the common side effects of regular SSRI and SNRI. Actions: vasodilator, mild antiseptic, cholagogue.
As with all nutritive supplements, note possible interactions. It can be bought in most European countries as tea or extract.
Powerful emotional distress can cause a broken heart condition with symptoms similar to the onset of a heart attack. Fortunately, it is treatable.
Yet more proof that it’s all in your head.
