Sneaky Lipid Molecules: A Hidden Role in Macrophage Cleanup

Macrophages, the body's cleanup crew, swallow dead cells through a process called efferocytosis. During this cleanup, they make special lipid molecules using oxygenases. Among these, very reactive lipid-derived electrophiles (LDEs) can modify important proteins inside the cells. But until now, we di

Fake Meat: Processed or Healthy? It's Not So Simple

Let's talk about those trendy plant-based burgers and sausages. Companies like Beyond Meat and Impossible Foods are really pushing the idea that their fake meats are super healthy. They've even changed their recipes to make them sound better. But hold on a minute! Are they really as good as they cla

Boosting CO₂ Conversion: How Solvents Help

Scientists are exploring a new way to turn carbon dioxide (CO₂) into useful chemicals. This process, called electrochemical CO₂ reduction (CO₂RR), uses a special setup called a membrane electrode assembly (MEA). The key is to design a good environment for the reaction to happen. This involves a laye

Blue Origin's New Glenn Rocket Takes Off, but Landing Fails

Thursday morning, Blue Origin, a company started by Amazon's Jeff Bezos, made a big step. They launched New Glenn, their first rocket strong enough to send satellites into space. This happened at Cape Canaveral Space Force Station in Florida. The rocket took off after 2 a. m. ET and carried a piece

Watching Receptors Move in Living Cells: A Scientific Dance

Picture this: scientists trying to follow tiny dancers on a bustling stage. In this case, the dancers are CB2 receptors, and the stage is the surface of living cells. To make these receptors visible, researchers used a special light-up tag called RO7304924. This tag attaches only to CB2 receptors, m

Sensors in Action: Making Smart Devices to Detect Chemicals
