Nancy Pelosi is retiring after decades of service. I still remember when I received my first R01, and she sent me a congratulatory letter!

Does anyone else have dogs that ruin their sleep score? I was all good till 7am, but then an intermittent Mastiff with a HrV of 300 took over

After clearly saving changes to an NIH RPPR form, the system inevitably gives this warning.

Politicized research comes and goes, but it always leave behind a legacy of permanent paperwork.

Shutting down the NIH guide for grants was a bad idea. Sure, the grant postings were redundant with grants.gov, but grants.gov posts ALL grant opportunities across the government. My inbox is now flooded with irrelevant calls from the Department of Labor

The Nature brand is strong. Just came across yet another variant, though I don't think this one is affiliated with Springer

25K people at my institution have taken and rated Security Awareness training at my institution. How is it rated 4.16/5? This is 30 minutes of my life (at 1.5X speed) that I will never get back.

In summary, we believe that UV radiation will, over decades, damage interfollicular melanocytes, killing off some cells. These cells are replenished from stem cells in the hair bulge. It is a clever adaptation to rejuvenate damaged skin. [10]

Indeed, melanocytes that express LowMut gene expression profiles were enriched in the hair bulge. They could also be found in the interfollicular epidermis, where they were somewhat more abundant near the opening of the hair shaft. [9]

Third, we explored morphologic features, indicating that low mutation burden melanocytes are smaller with fewer dendrites. Others have noted that melanocyte stem cells in the hair bulge share similar morphologic features [7]

First, we explored mutational signatures, indicating that low mutation burden melanocytes evade the worst of UV-radiation-induced mutagenesis. [5]

Most melanocytes in heavily sun exposed skin have high mutation burdens, but we were stunned to see that there is a subpopulation of melanocytes with virtually no mutational damage. [3]

We have now genotyped ~300 skin cells from over 50 different donors (available in cbioportal and dbgap). Their mutation burdens vary from person to person, site to site within each person, and cell to cell within each site. In this manuscript, we explore the latter source of variability. [2]

How much does a graduate student actually make at UCSF? I am pointed to a byzantine table, in which I am told their efforts fluctuate, depending on classwork. So a 1st year would be somewhere between 32K and 65K? There are further complexities surrounding the entry point.

Setting these reservations aside, I am a scientist who can be persuaded by evidence. I will try out this place out for awhile, side by side with X, and see how it goes

Is it possible we were overzealous with COVID restrictions?! Maybe we would benefit from hearing the other side a bit more, challenging our views.

Instead, we need a seat at the table where we tell Trump supporters when and why they are wrong. And while I think the scientific community is right more than it is wrong, we do get things wrong.

The election was not a gimmicky electoral college victory – more people in this country wanted Trump to be president than Harris. Scientists cannot plug their ears, accuse the majority of the country of being bigots, and ask for tax-funded scientific research.

If the Blue Sky is a silo for progressives, then I don’t see this working out the way we want. Jack Dorsey has expressed this concern and already renounced it. I was not happy with the recent election results, but it was humbling.
