Scientists at the University of Bristol are studying the "ears" of locusts, membranes that oscillate on the scale of nanometers. (A nanometer is one-billionth of a meter.) They're also measuring the movements of mosquito antennae (seen here) in response to sound. According to the researchers, insights into insect hearing could someday lead to novel microphone technology inspired by nature.
From a press release (photo by D. Robert):
Professor Daniel Robert is the research leader at Bristol: "We have found that different sound frequencies elicit very different mechanical responses in the locust hearing system. By studying these tiny nanoscale movements and understanding how sound waves are turned into mechanical responses we may be able to develop microphones based on the functions of natural hearing. These could detect very faint sounds and analyse their frequency, something that current microphones cannot pick up."
Mark Di Stefano of the Financial Times is accused by The Independent of accessing private Zoom meetings held by The Independent and The Evening Standard as journalists were learning how coronavirus restrictions would affect them.
Hackers tried to break into the World Health Organization earlier in March, as the COVID-19 pandemic spread, Reuters reports.

A senior agency official says the WHO has been facing a more than two-fold increase in cyberattacks since the coronavirus pandemic began.

When revved-up kids used to dribble a basketball through the kitchen or practice their footwork with a soccer ball in front of the television, exasperated parents would often just send ‘em outside to play. But these days, sending kids out might not be the best course of action. Despite all the changes, many budding young […]
