À cause de la flambée des prix des engrais, le fumier fait un retour en force chez les agriculteurs

7,000 false positives per square millimeter. The culprit was the lab gloves. University of Michigan researchers just upended a core assumption in microplastics science. Latex and nitrile gloves, worn by the scientists doing the measuring, shed stearate particles that look chemically identical to polyethylene. Standard infrared and Raman instruments can't tell them apart. The gloves were counting as plastic. Seven glove types tested. All contaminated. The cheapest fix: switch to cleanroom gloves, which dropped false positives to around 100 per mm² vs. 7,000. The "credit card per week" headline (5 grams, WWF/Newcastle 2019) has separate problems. A 2022 re-analysis found severe methodological errors in the original estimate. Actual measured intake is likely 100x lower. None of this means microplastics are harmless. Last month's data on brain accumulation still stands. But the numbers driving the panic may have been measuring the scientists, not the environment. Science catching its own errors is exactly how it's supposed to work.

A rescue operation is currently underway in Kyiv at the site of a Russian drone strike on a nine-story residential building – an entire section of the building has been completely destroyed. Dozens of people have been rescued. Tragically, one person has been killed. My condolences to their family and loved ones. People may still be trapped under the rubble. Overnight, the Russians launched more than 670 attack drones and 56 missiles against Ukraine. Ballistic, aeroballistic, and cruise missiles were used in the strikes. The main target of this attack was Kyiv. There is damage at twenty locations across the city – ordinary residential buildings, a school, a veterinary clinic, and other purely civilian infrastructure. Destruction has also been reported in the Kyiv region, while similar terrorist strikes targeted energy infrastructure in Kremenchuk, as well as port and residential areas in Chornomorsk. In total, since midnight yesterday, Russia has used more than 1,560 drones against our cities and communities. These are definitely not the actions of those who believe the war is coming to an end. It is important that partners do not remain silent about this strike. And it is equally important to continue supporting the protection of our skies. The PURL initiative is needed so that Ukraine can defend itself against ballistic strikes like these. And likewise, in the interests of everyone seeking peace, pressure on Russia must continue. I thank everyone who stands with Ukraine.
