Extreme heat is a problem in Southern European countries & cities, aggravated by rising temperatures & aging populations. Research on mobility during extreme heat remains limited to small samples & geographic contexts, leaving gaps in our systematic understanding of how populations adjust their day-to-day mobility patterns & how these adaptations vary across social groups.

An opinion piece in #PNAS (Proceedings of the National Academy of Sciences) suggests that to help the overwhelmed #PeerReview system in #science, a transparent universal credit system should be established to incentivize peer review: https://www.pnas.org/doi/10.1073/pnas.2506681123.

Nah. Peer reviewers need to be paid #income for their work! And one associate professor says, in a comment on Bluesky, that for-profit #publishers should pay peer reviewers.

La rivista #Pnas ha ritirato uno studio che annunciava la regressione completa del tumore al pancreas in 45 topi, risultato che aveva acceso forti aspettative e raccolto 3,6 milioni di euro in donazioni.

Indovina indovina? Conflitto di interessi: il ricercatore è lo stesso cofondatore della società che produce le molecole testate.

Top.

🐱👶 Researchers from #Cornell and #Washington University used #3D imaging to show how artificial selection pushes #cats and #dogs toward similar "baby-faced" skull shapes.

The study indicates that flat-faced breeds share more traits with each other than with their own wild ancestors.

Safety meltdown: Trump’s weakening of nuclear reactor regulations sparks opposition
"
".. attorneys general from several states .. announced they’ve formed a coalition to oppose the Trump administration’s new rules slashing security and environmental requirements for experimental nuclear reactors."

".. creation of “much more nuclear waste.”"

Edit: so the direct submission is just normal, and the journal also has a "contributed submissions" but it seems that's also peer-reviewed:
https://www.pnas.org/author-center/member-contributed-submissions
Maybe my info was just outdated 🤔

Edit 2: actually, it looks like the authors in that contributed submission case can choose their reviewers 🤔🤔

"Contributed submissions must include the names of at least two experts in relevant subject areas (particularly for multidisciplinary studies) who have agreed to review the manuscript."

-- original post --
Question about direct submissions in the journal #PNAS to anyone who might know:

Some of the articles there are noted as "direct submissions" - does this mean that these manuscripts do not go through peer-review before being published?
Isn't that strange?
Shouldn't these papers be considered similar to preprints?
Why would anyone want to do this instead of going through the peer-review process or posting as a preprint?
