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.

An affable honey-cream Labrador retriever named Aldo is helping young Ecuadorean children relax at the dentist's office, allowing them to cuddle up and stroke him to distract them from noisy machines and invasive oral procedures.
With some five years' experience in emotional support, 8-year-old Aldo understands some 30 commands and enjoys climbing on top of children sitting in his owner Glenda Arias' dental chair.
"Visits always tend to be traumatic, but Aldo brings tranquility and peace to my daughter," said mother Beatriz Armas. "These visits are totally pleasant for her."
Arias said Aldo's clinical involvement had helped transform the behavior of children attending her consultations.
"Aldo is essential," she said.
