| Attitudes around older motherhood too often emphasize risk and pregnancy timing Posted: 22 Jun 2022 11:18 AM PDT A political science professor argues that much of the official language around older motherhood is rooted in both ageism and ableism, as well as being out of step with current childbirth trends. The average age of childbirth has been rising steadily since the mid-1960s, and in some countries, more women are giving birth between the ages of 35 to 39 than between 20 and 24. But societal expectations of mothers remain largely unchanged. |

| Optical microphone sees sound like never before Posted: 22 Jun 2022 07:14 AM PDT A camera system can see sound vibrations with such precision and detail that it can reconstruct the music of a single instrument in a band or orchestra. Even the most high-powered and directed microphones can't eliminate nearby sounds, ambient noise and the effect of acoustics when they capture audio. The novel system uses two cameras and a laser to sense high-speed, low-amplitude surface vibrations. These vibrations can be used to reconstruct sound, capturing isolated audio without inference or a microphone. 'We've invented a new way to see sound,' said Mark Sheinin, a post-doctoral research associate at the Illumination and Imaging Laboratory (ILIM) in the RI. |
