🫀🇫🇷 This isn’t science fiction: French engineers developed an artificial heart that can actually adjust blood flow depending on what the person is doing. It’s called Aeson, and it was developed by the French medical-technology company CARMAT for some of the sickest heart-failure patients — people whose two ventricles can no longer pump enough blood to keep the body alive. And unlike a traditional mechanical pump, Aeson was designed to behave more like a human heart. Inside the device are sensors and an automatic control system that continuously adapt blood flow to the patient’s physiological needs. Resting? The flow can decrease. Standing up or becoming more active? The system can respond automatically. CARMAT describes this as real-time autoregulation, one of the features intended to make the artificial heart more physiological than earlier mechanical systems. But perhaps the most fascinating part is what actually comes into contact with the patient’s blood. The device contains flexible membranes partly made from treated bovine pericardial tissue — biological tissue taken from the sac surrounding a cow’s heart. one of the great challenges with mechanical circulatory devices is blood interacting with artificial surfaces. That interaction can contribute to dangerous clotting or bleeding. Aeson was engineered with hemocompatibility in mind, specifically to try to reduce these complications. So it isn’t accurate to say that the biological material prevents “organ rejection” in the way anti-rejection drugs are needed after a human transplant. The goal is primarily to make the device more compatible with circulating blood. 🔋 And the patient isn’t permanently attached to a giant machine beside a hospital bed. The implanted heart is connected to a portable external power and monitoring system, including batteries, allowing patients a degree of mobility.

Weather Changes Bring Roaches/Rats Problems for Some Residents As seasonal weather patterns shift, some residents are reporting increased problems with roaches and rats around homes, apartment buildings, and other residential areas. Changes in temperature and moisture can cause pests to move in search of food, water, and shelter, creating new challenges for households already dealing with difficult living conditions. Roaches may become more noticeable when temperatures fluctuate, particularly when warmer conditions drive them indoors or when changes in moisture create favorable environments. Rats and other rodents can also seek shelter inside buildings as outdoor conditions become less comfortable. Residents dealing with infestations say the problem can extend beyond individual apartments or homes. Garbage accumulation, open food sources, standing water, cracks around doors and foundations, and poorly maintained building areas can all provide opportunities for pests to survive and reproduce. Property managers and landlords are generally responsible for addressing conditions that contribute to infestations, while residents can reduce attractants by keeping food sealed, removing garbage regularly, cleaning spills, and reporting leaks or structural openings. Pest-control professionals recommend addressing signs of an infestation quickly rather than waiting for the problem to become widespread. Evidence such as droppings, damaged food packaging, nesting materials, unusual odors, or increased pest activity can indicate that additional measures are needed. For residents experiencing repeated problems, documenting sightings and reporting them to property management or the appropriate local housing authority may help establish a record of ongoing conditions. As weather continues to change from one season to another, residents are being reminded that pest activity can change as well. Maintaining clean surroundings, repairing building defects, and responding quickly to

☀️ Germany is dropping €2+ billion to trap the Sun in a box—and it could help reshape the world’s energy system by 2040. Munich’s Proxima Fusion, a Max Planck spin-off, is developing a stellarator with magnetic fields shaped with extraordinary precision to confine plasma at temperatures of millions of degrees. Phase 1: Alpha comes first near Munich in the early 2030s, designed to demonstrate net energy gain. Phase 2: Stellaris is planned for the former Gundremmingen nuclear site in Bavaria, with the goal of putting fusion electricity on the grid in the 2030s. No fossil fuels. No conventional high-level radioactive waste stream from fission. And there’s something almost poetic about the location: A site once built to split atoms could become part of Germany’s effort to fuse them. If the technology works as its developers hope, the energy story of the 2040s could look very different.
