每日英語跟讀 Ep.879: About Britain - Shopping robots come into their own in locked-down English town
A fleet of robots on wheels that deliver shopping in the English town of Milton Keynes have seen their popularity surge as residents are stuck indoors due to the coronavirus lockdown.
The robots, which come up roughly to an adult’s knee height and look like smooth white plastic boxes mounted on six black wheels, are a familiar sight in the town, where they have been delivering groceries for over two years.
But since the government imposed strict social distancing measures on March 23, the devices have been busier than ever, delivering for free to National Health Service (NHS) staff and facing increased demand from the general public.
The robots have what looks like an antenna, topped with a small red flag to make it easier to spot them as they do their rounds.
Britain starts training dogs to detect new coronavirus 英國開始訓練狗來偵測新型冠狀病毒
Canines have been used for decades to sniff out drugs, bombs, corpses and even cancer.
Now, a team of British researches are hoping dogs’ keen sense of smell can help detect COVID-19, CNN reports.
The London School of Hygiene and Tropical Medicine is working with specially trained dogs to develop a new kind of coronavirus test, one that doesn’t require a swab, but just a sniff.
The organization recently discovered canines can detect Malaria infections in humans and they are investigating whether the same is true for COVID-19.
The training began in March and researchers are eyeing six weeks as enough to determine if the dogs are up to snuff.
If the tests go well, these "super sniffers" could be deployed to screen up to 250 people per hour for the virus.
Researchers said the dogs could be used at airports and other public areas in the future to help prevent another outbreak once the current pandemic declines.
