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.

Heavy rain hit northern Japan Thursday, triggering floods and landslides, disrupting transportation systems and forcing hundreds of residents to take shelter at safer grounds.

The Japan Meteorological Agency issued emergency warnings of heavy rain for several municipalities in the Yamagata and Akita prefecture, where warm and humid air was flowing.

Prime Minister Fumio Kishida urged the affected area’s residents to “put safety first” and pay close attention to the latest information from the authorities.

According to the Fire and Disaster Management Agency, one person went missing in Yuzawa city — in the Akita prefecture — after being hit by a landslide at a road construction site.

Rescue workers in the city evacuated 11 people from the flooded area with the help of a boat.

In the neighboring Yamagata prefecture, more than 10 centimeters (4 inches) of rain fell in the hardest-hit Yuza and Sakata towns within an hour earlier Thursday.

Thousands of residents in the area were advised to take shelter at higher and safer grounds, but it was not immediately known how many people took that advice.

Yamagata Shinkansen bullet train services were partially suspended on Thursday, according to East Japan Railway Company.

The agency predicted up to 20 centimeters (8 inches) of more rainfall in the region through Friday evening, urging residents to remain cautious.
