Scientists Turn Cockroaches into Superbugs to Help Rescuers in Disaster Sites

Cockroaches are known to infiltrate homes through the tiniest of gaps, and this innate ability now has engineers in Singapore working to turn the pesky insect into an ally of rescuers at disaster sites.

One variety of the insect, in particular, has the team at Nanyang Technological University (NTU) excited – the Madagascar hissing cockroach. On average, an adult is 6cm long, 2cm longer than the local variety.

The species is large enough for associate professor Hirotaka Sato and his team at the school of mechanical and aerospace engineering, to equip the bug with a 5.5g “backpack” consisting of several sensors, including those that can warn of the presence of gasses such as carbon dioxide.

The cyborg bugs also carry a small infrared camera that can detect life by picking up temperature signatures. The idea is to release a team of them at a disaster site.

Prof. Sato’s research, which started four years ago, is being conducted in partnership with Singapore’s Home Team Science and Technology Agency (HTX) and engineering firm Klass Engineering and Solutions.

With Nepal's snowy Himalayan peaks as a backdrop, the sky above Pokhara transformed into a vibrant canvas of colors for the country's first hot-air balloon festival.

Tourism is a major earner for Nepal, which saw over a million foreign visitors this year after a post-pandemic bounceback, and investments are being made in hotels and airports to cater to travelers.

"We felt that we must bring a balloon festival like this to Nepal," Sabin Maharjan, an organizer of the event, told AFP.

Hot-air balloons from more than 10 countries participated in the festival.

"A ride here can be very exciting as you can see mountains, hills and lakes," Maharjan added.

"All passengers tell us that they are very happy -- such a festival will boost our tourism."

The balloons created a mesmerizing display against a stunning sight of the snow-capped Annapurna range.

"It is spectacular," American balloon pilot Derek Hamcock, 67, said.

"As soon as you go above the small range here you see all the Himalayas. Unbelievable, every time you see them it is unbelievable."

Balloons shaped as a rat and a frog from were among those joining in the fun, slowly drifting with the breeze.

"You never know where you are going," said Diego Criado del Rey, 29, a balloon pilot from Spain.

"So it is pretty much you and the nature -- not fighting, but being together. You go where the nature tells you."

Nepal's Civil Aviation Authority issued a notice for the skies over Pokhara for a duration of nine days to allow balloon flights.

Although more than two centuries have passed since France's Montgolfier brothers made the first manned flight, ballooning can still capture the imagination.
