New Theory Claims to Unite Einstein's Gravity with Quantum Mechanics
Phys.Org, December 04, 2023
Modern physics is founded upon two pillars: quantum theory on the one hand, which governs the smallest particles in the universe, and Einstein's theory of general relativity on the other, which explains gravity through the bending of spacetime. But these two theories are in contradiction with each other and a reconciliation has remained elusive for over a century.

Years After Monsanto Deal, Bayer’s Roundup Bills Keep Piling Up
New York Times, December 06, 2023
Juries recently awarded plaintiffs more than $2 billion in damages tied to Roundup, the weedkiller that has been linked to cancer. Monsanto started using the chemical glyphosate, the main ingredient in Roundup, in the 1970s to kill weeds. It was only after the company developed genetically modified seeds in the late 1990s, however, that Roundup became the dominant weedkiller. The G.M.O. seeds were immune to Roundup, so farmers could spray it on fields, killing weeds but not the crops. Monsanto then built a giant global business by controlling the so-called glyphosate platform for both the weedkiller and the seeds resistant to it.
