A few science news items caught my eye this week.Wood-Shattering Revelation: Termites have been recategorized based on genetic and other evidence. Turns out, they are just social cockroaches and thus, have become part of the cockroach order Blattodea rather than remaining in a separate order. This decision was not made lightly, but based on years of debate amongst American entomologists. The insects will still retain termite in their name, but they gain a reputation for surviving apocalyptic events. Read about the update to the insect name master list by the Entomological Society of America. Blood Pressure Measurements at the Tip of Your Finger: A blood pressure cuff is bulky, annoying but accurate for monitoring the effort needed for pushing blood around your body. While this device is a fairly simple one, in the developing world it is not that common. However, mobile phones are available to many more globally so why not find a way to put the two together? Turns out that smartphones are equipped with hardware that can be used to measure blood pressure. By adding a device that attaches to the back of a smartphone and with the press of a finger, you can monitor your blood pressure. While not currently as accurate as a blood pressure cuff, the people that tried the mobile blood pressure device were able to quickly adapt to using it, making it easy to take several readings for continuous monitoring. A pocket-sized blood pressure monitor without the nasty squeeze of your arm sounds like a great medical advancement for treating high blood pressure. See a video of the device. For a Forensic ID, All You Needed Was a Picture, Old Clothing and Some Numbers: The quest to find where Amelia Earhart may have landed in the Pacific Ocean has been investigated and speculated about since she and her navigator disappeared July 2, 1937. In fact, skeletal remains had been found on a remote island in the South Pacific in 1940 along with other artifacts–a woman’s shoe, an American sextant box, but the bones were identified as a man by a physician at the time. Unfortunately, these remains have subsequently been lost. Recently, an anthropologist decided to take the measurements made in 1940, and using a modern-day techniques including a program that estimates stature, sex and ancestry, and he found that the bone measurements were more consistent with Earhart than with 99% of the reference sample used. In addition, using a photograph of the American pilot that had scale generated bone lengths of her humerus and radius and measuring her clothing from a collection gave a number for her tibia. All these numbers strongly suggest the skeletal remains were Earhart’s. Read the press release.
