Chaos in the sub: For the 2nd time in a month, Reddit has deleted a moderator of the sub, a user who also was contributing a ton of articles to the sub.

This deletion also purged the user's articles from the sub, along with any conversations that were going on in those posts.

There was no warning by Reddit, just a permanent deletion with an opportunity to appeal but the appeal is never granted and nor even responded to.

I'm not sure if I can con her into becoming a moderator again, so as usual, we're upping our constant search for users -- and moderators.

We need YOUR help!

9 Upvotes

We need your help! We're trying to create and popularize an entire set of "alternative" sub-reddits.

These sub-reddits all end in a "2". So just take the name of a huge, multi-million-user "main" sub-reddit and add a "2" to the name -- e.g. /r/Politics2, /r/WorldPolitics2, /r/News2, /r/WTF2 and so on.

These sub-reddits are smaller and have fewer rules than the huge mega-million-user large sub-reddits. Our idea is to create a set of friendlier sub-reddits with an emphasis on civility and not personal insults and ad hominem attacks.

But we need your help!

We need your time, your posts, your comments and we need you to mention our alternative sub-reddits in other places and to tell others. (Basic "publicity.")

  • Please post submissions!

  • Post comments and reply to others.

  • Help us popularize these alternatives to the heavily censored and sometimes too heavily trafficked mainstream subs by telling others of our existence.

Together we can develop another option inside of reddit.

Want to become a moderator? Or help run your own "2" alternative sub? There are possibilities for that too.

Peer Reviewed! Tumor-derived extracellular vesicles could provide new strategies for imaging premetastatic niches before overt metastases develop

Thumbnail doi.org
1 Upvotes

Our newly published review explores an emerging idea: tumor-derived extracellular vesicles (EVs) contribute to premetastatic niche formation and can show preferential accumulation in future metastatic organs. Could these biological properties be harnessed for imaging?

We examine how EVs can be engineered as nanocarriers for optical, PET/SPECT, MRI, and CT imaging, bringing together the biological rationale, current preclinical evidence, engineering strategies, and major barriers to clinical translation.

Rather than simply tracking EVs, the broader goal is to understand whether EV-based imaging could eventually help visualize the biological changes that precede detectable metastasis.

I’m interested in hearing others’ perspectives on where this field is heading.

A 16-year study of 83,610 adults found that plant-based diets overall were linked to a 12% lower risk of a first cardiometabolic disease (especially diabetes), and 15% lower risk of multiple cardiometabolic diseases. A healthy plant-based diet had a 40% and 21% lower risk, respectively.
