At COP28, oil-rich Colombia moves to end fossil fuels and protect forests Colombian Environment Minister Susana Muhamad said her country is reducing fossil fuels and deforestation, but global economics don't support climate action.

politicians, media and large institutions deciding to stop saying 'climate change' hasn't materially reduced public conern about it or support for actions to tackle it

turns out people genuinely do not want to be baked alive by the atmosphere they're in!!!

Men are afraid that women will laugh at them, women are afraid men will kill them.

I've seen this quote before, didn't realize it was Atwood's! And yes, not all men, but enough that this is a reality.

Asymmetric Diamination of the In Situ Generated Difluoroenol Species Using Azocarboxamides as an N Source The Rh2(esp)2 and Zn(II)-bisoxazoline (BOX) complex-cocatalyzed asymmetric diamination of in situ generated difluoroenol species with azocarboxamides has been disclosed. This reaction features a formal [3 + 2]-cycloaddition reaction using difluoroenol intermediate as a C2 synthon, providing an efficient and robust approach for the synthesis of difluorinated imidazolidin-2-ones in good yields with high to excellent stereoselectivity (up to 95% ee). This method offers a complementary approach for the direct assembly of chiral difluoromethylene incorporated heterocycles by introducing in situ formed difluoroenol species as a practical C2 synthon rather than using presynthesized gem-difluoroalkenes. With this protocol, further synthetic applications in fluorine chemistry could be envisioned through the strategic interception of difluoroenol via cycloaddition reactions with appropriate partners.

Patel's girlfriend performed at Penn State last weekend. A government jet arrived at State College Regional Airport, according to its FAA registration, with an address listing the FBI HQ. The plane then flew to Nashville, where his girlfriend lives.

All on the taxpayer’s dime.

Here’s the original clip of Ronald Reagan from April 25, 1987, where he delivered a complete and total rebuke against tariffs. Trump's calling Reagan’s words here β€œFAKE” and β€œfraudulent.” They’re 100% real. And the original clip is actually far worse for Trump, as much is left out of the ad:
