Short answer

Several possible studies

No clear answer.

More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.

Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Evidence layer

Claim by claim

What the story asserts. With no source study, there is nothing to check these against.

Claim 1 of 6Not checkedA new study published in Cell found that caloric restriction reduced the level of mutations across several tissues in mice fed 30% fewer calories than they would have eaten freely.View evidenceHide evidence

As stated30% fewer calories

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 2 of 6Not checkedThe story says prior work had examined single genes, but this study looked across a large portion of the genome and reported the first genome-wide assessment of caloric restriction's impact on mutation patterns.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 3 of 6Not checkedThe article says caloric restriction dialed down substitution mutations and insertion-deletion mutations to varying degrees across tissues.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 4 of 6Not checkedThe story reports that the effect varied by tissue, with liver cells showing a greater reduction in mutation burdens than kidney or brain cells.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 5 of 6Not checkedIn liver and kidney cells, the reduction in mutations was greatest in the least active regions of the genome.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 6 of 6Not checkedThe article frames the work as potentially helping researchers understand how to reduce mutations without the challenges and risks of an extreme diet.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.
