While researchers have long been familiar with the surface structure of lymphatic vessels, a groundbreaking study has now focused on their jigsaw puzzle-like pattern. This arrangement helps cells tolerate changes in fluid pressure, such as swelling. Similar cell shapes are found on the surface of plant leaves, and the principle has been employed in human-led design as well.

Though we learn so much during our first years of life, we can't, as adults, remember specific events from that time. Researchers have long believed we don't hold onto these experiences because the part of the brain responsible for saving memories -- the hippocampus -- is still developing well into adolescence and just can't encode memories in our earliest years. But new research finds evidence that's not the case. In a study, researchers showed infants new images and later tested whether they remembered them. When an infant's hippocampus was more active upon seeing an image the first time, they were more likely to appear to recognize that image later. The findings indicate that memories can indeed be encoded in our brains in our first years of life. And the researchers are now looking into what happens to those memories over time.
