AI is not a peer, so it can’t do peer review If we still believe that science is a vocation grounded in argument, curiosity and care, we can’t delegate judgement to machines, says Akhil Bhardwaj

'to treat peer review as a throughput problem is to misunderstand what is at stake. Review is not simply a production stage in the research pipeline; it is one of the few remaining spaces where the scientific community talks to itself.' 1/3

The EU’s Horizon research fund needs to stay a defence-free zone It is time to sound the alarm as the EU’s research priorities face an unprecedented degree of political interference.

A friend was offered a fantastic, five-year postdoc position at a Germany university. When the university's HR found out she is undergoing cancer treatment (with very good chances of complete recovery), they forced the PI to withdraw the offer. These stories are not uncommon from Germany. Why?

“Why Are We Funding This?” Long-standing myths about “silly science” have contributed to the reckless slashing of government-supported research.

www.americanscientist.org/article/%E2%...

in my view the problem started when we forced basic science to be translational. this distorted it's nature and created false expectations, which in turn eroded the trust on basic science.

The low endoribonuclease activity and lack of rNMP preference of human mitochondrial topoisomerase 1 protect against ribonucleotide-dependent deletions Abstract. The incorporation of ribonucleotides (rNMPs) into the nuclear genome leads to severe genomic instability, including strand breaks and short 2–5 b

Our newest paper on mitochondrial Topoisomerase 1 shows that Top1mt has only weak endoribonuclease activity and it therefore does not often generate deletions at incorporated ribonucleotides. This helps explain why ribonucleotides are tolerated in mtDNA. Read more:

Two mtDNA papers of ours in one PNAS issue:
#1 on the Y951N patient mutation of PolG, heroically spear-headed by Josefin Forslund
#2 revealing surprising dNTP imbalance & subsequent mtDNA depletion in RRM2B-deficient mice, a great collaboration with the Chabes lab
