Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

From this article: https://arstechnica.com/science/2024/04/swimming-and-spinning-aquatic-spiders-use-slick-survival-strategies/
Spiders already possess some adaptations that help in the water, such as hairs that repel water and trap air around them (a).
The diving bell spider Argyroneta aquatica uses these hairs to transport a large volume of air to its underwater canopy (b).
Other spiders burrow under the sand and surround their nests with waterproof silken barriers to stay safe when the tide is high (c).
Desis marina builds its own watertight silk nest in the holdfast where bull kelp attaches to rocks (d).
Other spiders, such as Marpissa marina, build their waterproof nests inside old seashells (e).

(Sorry, can't seem to find a higher-res photo!)
Link to the article with a description of each, and maybe a little on the history or place of origin: https://www.apetimemagazine.com/40-tipi-di-caffe-in-italia-li-conosci-tutti/
It's in Italian though, so hopefully you can use "translate" on your phone or desktop!

The chemistry behind new and old book smells
cross-posted from: https://mstdn.social/users/compoundchem/statuses/112053145362352366
Image description: Infographic on the aroma of books. The smell of old books is produced by the gradual breakdown of cellulose and lignin in paper. Type of paper and age of the book affect the compounds produced, which include furfural, vanillin and benzaldehyde. The aroma of new books is equally variable, the compounds causing it coming from adhesives, inks, and chemicals used for paper treatment. Many of these chemicals are odorless themselves, but can react and contribute to the release of aroma chemicals.
