Even though little kids remember plenty, most of us lose access to key memories as we get older. It's something scientists call childhood amnesia. We explore just that in a recent episode of the Ask Us Anything podcast, delving into the science behind why our brains forget our earliest memories. 's Ask Us Anything podcast (as well as our written series of the same name) answers your most outlandish, mind-burning questions--from the everyday things you've always wondered to the bizarre things you never thought to ask.

A sugar mixture similar to hard candy studded with tiny metal discs or rings has been used to deposit patterns onto microscopic objects. This method of creating texture on small objects could be useful for biomedical robots or flexible electronics. To give microscopic robots or small electronic circuits more functionality, researchers often embellish their surfaces with patterns of even tinier objects, such as magnets. They often make these components on a flat, clean surface and then stamp them onto the bigger object. But accurately applying them in this way becomes difficult when the receiving objects are not smooth, says Gary Zabow at the National Institute of Standards and Technology in Colorado.
