Sunspots 247

Things I have recently spotted that may be of interest to someone else:



Science:NPR reports on the difficulty of seeing some things against some backgrounds, such as cancers in breast X-rays, or weapons in luggage screens at airports.

NPR also reports on why events, like Christmas and our birthday, seem to get closer together as we age.

NPR says that blue whale songs are lower-pitched now than they used to be. You can hear audio from this link.
