A new high-tech alarm system, designed by two international technology companies in South Africa and California, is helping rangers stop poachers from killing rhinos and other wildlife, reports National Geographic.

The details: The device, Connected Conservation, detects human movement and suspicious activity on reserves. Rangers have so far used it in a 135,000-acre reserve that has almost 150 mammal species. Between 2013 and 2015, before the device was installed, poachers in the area killed 70 rhinos for their horns. In 2017, no rhinos were poached, per the report. The companies plan to release a second second phase of the technology in June to bluster its capabilities.

Boeing and researchers at the University of Arizona say their experiment with a live virus on an unoccupied airplane proves that the cleaning methods currently used by airlines are effective in destroying the virus that causes COVID-19.

Why it matters: Deep cleaning aircraft between flights is one of many tactics the airline industry is using to try to restore public confidence in flying during the pandemic. The researchers say their study proves there is virtually no risk of transmission from touching objects including armrests, tray tables, overhead bins or lavatory handles on a plane.
