Any time the Administration puts forward a policy to undermine renewable energy, they are increasing our energy bills, harming our health, and damaging our climate, all just to financially reward (and subsidize) a favored industry.

As the country bakes in a heat wave, it’s #ShowYourStripes day. With my younger son just graduating from elementary school, it’s sobering to compare how much hotter his world is than when I was his age. Even more sobering to think of what his kids will experience. Time for action!

It’s hard to get public sympathy for Harvard losing money. But this assault is killing jobs and destroying careers, with incalculable losses of knowledge about science and health. And if this stands, any school, non-profit, or business could be at risk just for making the administration mad.

One of my favorite pictures today from the #MarchforScience (borrowed from a colleague)
Indirect costs include the jobs of people who make the research enterprise work, including grants administrators, custodial staff, and many others. Cut IDC = lost jobs and destroyed research infrastructure.

Playing along and pretending Elon’s email is a good faith attempt to increase efficiency, asking for a weekly list of emailed accomplishments is classic bad personnel management.
It encourages short-term and individualistic tasks over collaborative efforts that could yield long-term benefits.

Fascinating to see these paragraphs in side-by-side articles this morning - institutions fearful of speaking out against the RFK Jr nomination, to avoid retribution, find that they are attacked nevertheless.
