I’m looking for an automated way to read others’s scientific data without giving credit or acknowledgement, and also claim full credit for insights from it. And I want it to have a fitting name

Also, it's retroactively hurting people who applied before knowing these rule changes, or were already contemplating their future submissions. There must be a better way (and I think letting AI review/triage grants is horrible). E.g., increase the number of panels, or make virtual triage sub-panels

I can certainly sympathize with the plight of the panelists, but this is a wrong decision. The idea of ERC is encouraging high-risk proposals. Saying "if a couple of panelists think its too crazy", you are banned for 2-3 years is the opposite message of discouraging bold ideas

Saturation editing of RNU4-2 reveals distinct dominant and recessive disorders - Nature Saturation genome editing of RNU4-2 identifies the functional and clinical impact of variants across the entire gene and delineates variants that cause a new recessive neurodevelopmental disorder distinct from ReNU syndrome.

Super excited that our two companion papers on saturation genome editing (SGE) of RNU4-2 and discovery of a novel recessive neurodevelopmental disorder (NDD) were published yesterday 🥳

As a kid, watching Walker, Texas Ranger taught me that many problems in life can be solved by a well-timed roundhouse kick, a lesson that has served me well in academia

Regulation of neuroregeneration by long noncoding RNAs In mammals, neurons in the peripheral nervous system (PNS) have regenerative capacity following injury, but it is generally absent in the central nervous system (CNS). This difference is attributed, at least in part, to the intrinsic ability of PNS ...

Timely reminder that a few years ago we named the Norris1 lncRNA, which remains quite enigmatic, but, fittingly for Chuck, is expressed primarily in the testis pmc.ncbi.nlm.nih.gov/articles/PMC...

Transcript diversity reflects deleterious RNA processing errors shaped by population size in metazoans Alternative transcription initiation, splicing and polyadenylation generate extensive transcript diversity in eukaryotes, but its evolutionary significance has been disputed.

"This observation supports the error hypothesis and suggests that metazoan transcript diversity is largely deleterious." Love this since it matches my priors :-) dx.plos.org/10.1371/jour...

This is a fascinating paper that reveals defined and clear mechanism for a phenomenon that for some seemed unbelievable- the up regulation of genes paralogous to those with specific types of inactivating mutations. This is called transcriptional adaptation 1/ www.science.org/doi/10.1126/...

Ever notice that when one gene is disrupted, its orthologs get upregulated? This phenomenon, known as transcriptional adaptation, has been controversial and mysterious - glad to see that we are starting to learn how it works.

Proud to announce that I effectively executed a rapid-response squirrel displacement strategy to mitigate potential yard intrusions.

Humbled by the unwavering support of my family and local stakeholders.

This experience reinforced the importance of vigilance, ownership, and continuous improvement.

Looking forward to scaling this impact in future engagements.

A nowhere-to-hide mechanism ensures complete piRNA-directed DNA methylation - Nature In mice, a SPOCD1–TPR-dependent ‘nowhere-to-hide’ mechanism is required for complete non-stochastic piRNA-directed LINE1 DNA methylation by preventing transposons from escaping surveillance within heterochromatin.
