Biological age versus chronological age: What the science says - Stanford Medicine

Some preprint servers report being flooded with submissions.

The move follows a steep rise in submissions driven mainly by the slop generated by artificial-intelligence tools, says Steinn Sigurðsson, an astrophysicist at Pennsylvania State University in University Park and scientific director of arXiv. In September, 40,000 preprints were uploaded to arXiv, up from about 30,000 between March and July. Closing the floodgates The cap is the latest measure introduced by arXiv to prevent its nearly 300 voluntary moderators from being completely overwhelmed by submissions, says Sigurðsson. They are now collectively checking about 1,000 manuscripts per day. This step is “holding up too many legitimate papers,” Sigurðsson says, noting that nearly 4,000 submissions are currently waiting to be posted on the site. Some see the limit as entirely reasonable.

Evidence for intelligent design in nature may be clear to you, while other matters relevant to faith remain far more perplexing. Our physicist colleague Brian Miller talked with Jana Harmon on the eX-skeptic podcast, in a very personal conversation, and offered a helpful analogy. He agreed that, for him, there are “tensions” and “unanswered questions.” But here’s the difference. When you have, let’s say, a magnifying glass and you use that magnifying glass to see the small print on your medicine bottle, what happens is that [with the] magnifying glass, what’s in the center is very clear.
