The detected compounds comprised oxidized aliphatic chains, like 2-ketones from 10 to 22 carbons. Ketones from 10 to 18 carbons were identified by comparing the fragmentgram of the ion m/z 58 from methyl ketones that correspond with the transposition of the McLafferty on the carbonyl located at the second carbon of each ketone. Those not present in the library as 2-eicosanone and 2-docosanone showed the same fragmentgram m/z 58 and were defined by the equidistance of the peaks along the retention time and their molecular weight (Supplementary Table 1). Furthermore, the presence of 2-ketones was confirmed with GC-MS/MS in MRM mode with the ion with the highest m/z and the exclusive of each molecule as 212 > 58 for 2-tetradecanone, 240 > 59 for 2-hexadecanone, and 282 > 58 for 2-octadecanone. Also, butane, 2,3-Butanediol, 2-trimethylslyl (TMS) derivative, and sebacic acid, 2TMS derivative were identified using sample silylation, indicating the deterioration of the PE chain (Fig. 3C). At the same time, a small aromatic compound recognizable as benzenepropanoic acid, TMS derivative, a plastic antioxidant, was found. Derivative chemicals were confirmed as well using GC-MS/MS with an m/z of 147 > 73, 331 > 73, and 104 > 75, respectively. The presence of this plastic antioxidant suggests an “opening” in the polymeric structures, with the release of small stabilizing compounds normally present in plastics (plastic additives).
The Food and Drug Administration said Tuesday that fragments of the bird flu virus had been detected in some samples of pasteurized milk in the U.S. While the agency maintains that the milk is safe to drink, it notes that it is still waiting on the results of studies to confirm this....
Not too far fetched. Many vaccines are made with surface proteins from viruses that can be recognized by the immune system. But my guess is going through the pasteurization most proteins would be denatured and not in the functional form.

“During Navalny’s funeral, people realized that they are many and that there’s a way for them to show that their opinion counts,” Duntsova, the barred presidential hopeful, told POLITICO. “In today’s Russia, queues have become a symbol of dissent, a way to express your civic position.”
