In this series of posts about the electronic effects in small sulfur rings[cite]10.59350/rzepa.28615[/cite] I have explored increasingly large induced geometric effects. Here is the largest so far, for the compound S 7 I 1+ [cite]10.1021/ic50225a048[/cite] The calculated geometry[cite]10.14469/hpc/15236[/cite] is shown below, with the crystallographic values in parentheses – the two matching very well.

Der 14. Workshop der DINI Arbeitsgruppe Kompetenzzentrum Interoperable Metadaten (KIM) fand dieses Jahr wieder an der Uni Mannheim statt. Der jährliche Wechsel zwischen einer Veranstaltung vor Ort und eines Onlineformats hat sich mittlerweile etabliert und wurde auch von den diesjährigen Teilnehmenden als sehr passend empfunden.

The second trailer for Jurassic World Rebirth is out today, and there’s my baby at 1:35! I am completely certain that at some point the tide of Aquilops -themed merch will overwhelm my ability to keep up — not to mention your interest in keeping up with this blog — but for now I am happily in squee-land. Fortunately Mike is keeping the site turning over with some actual science content.

There’s a quiet revolution underway in how we think about global power. In the 20th century, alliances were built on the movement of oil, steel, and troops. In the 21st century, they’re being rebuilt on the movement of cells, code, and biological knowledge. This isn’t a metaphorical shift. It’s literal.

The two previous  posts[cite]10.59350/rzepa.28515[/cite],[cite]10.59350/rzepa.28407[/cite] on the topic of anomeric effects in 7-membered sulfur rings illustrated how orbital interactions between the lone pairs in the molecules and S-S bonds produced widely varying S-S bond lengths in the molecules, some are shorter than normal (which is ~2.05Å for e.g. the S 8 ring) by ~ 0.1Å and some are longer by ~0.24Å.

In a climate of funding uncertainty, what if the most cost-effective investments in global health weren’t about supplies or infrastructure, but human networks that turn learning into action? In this short review article, we explore how peer learning networks that connect human beings to learn from and support each other can transform health outcomes with minimal resources.
