Moo-ving out: Sensor sends text alerts from cows in labor
DURHAM, N.H. — University of New Hampshire dairy researchers are more relaxed these days about monitoring pregnant cows: A sensor attached to their tails sends text alerts to help detect when they're in labor.
Moocall measures tail movement patterns triggered by labor contractions. On average, it alerts dairy managers by cellphone and email about an hour before a cow gives birth.
Moocall was developed in Ireland and released commercially last year. The company says the University of Kentucky also uses the technology.
Doctoral student Kayla Aragona says with about 70 calves born every year at the farm, it's a help.
But it's not foolproof. One unhappy cow rubbed her tail up against everything and banged the sensor on the wall to try to get it to fall off, leading to false alarms.
Philadelphia museum puts early presidents' hair on display
PHILADELPHIA — Donald Trump's gravity-defying hair has generated plenty of attention, but have you seen George Washington's?
You can check it out this month in Philadelphia, where a museum has put the hair of some early presidents on display.
The Academy of Natural Sciences of Drexel University is showcasing locks of hair once belonging to Washington, Thomas Jefferson, John Adams, John Quincy Adams and Andrew Jackson. The exhibit, called "Presidential Archives: Letters, Hair and Fossils," runs through July 29, coinciding with the Democratic National Convention.
A Philadelphia attorney collected the specimens, which were given to the museum after his 1860 death.
Academy historian Robert Peck says it may seem like an odd hobby today. But he says it was once common for people to keep hair clippings from loved ones in "lockets, brooches, rings and pins."
