New treatment extends shelf life of bananas

Researchers have found a way to extend bananas' shelf life by up to 1-2 days through postharvest application of lysophosphatidylethanolamine (LPE). This natural phospholipid treatment maintains membrane integrity, reduces respiration and slows starch breakdown, making the fruit firmer and thicker.

How the stick insect sticks (and unsticks) itself

Insects like stick insects can walk up vertical surfaces using adhesive pads on their feet, but scientists long believed that wet and dry feet required different mechanisms to adhere. New research reveals that the fluid on their feet plays a crucial role in controlling adhesion, with potential applications in modern devices.
