One is a massive black ant, the other is a tiny, only distantly related, brown ant. But together they form a perfect team to build and guard a shared nest.
Desert ants: Same behavior outdoors and in the lab
These desert ants live in salt pans and are ideal models for navigation research. When they set out in search of food in their flat, bare, hostile environment, they are nevertheless always able to find their way back to their nest on the shortest route possible.
The Bot That Flies Like a Bat
Imagine a drone that could bounce off a building instead of crashing into it, or move safely and seamlessly among workers at a skyscraper under construction. While most drones cause damage when they collide with objects or people, a new flying robot promises safer flights by mimicking bat behavior.

A world without primates is unimaginable right now but a new report suggests that this could happen in the future. An extensive study of primates such as apes, monkeys, tarsiers, lemurs and lorises reveals a dramatic decline in their population and says that about 60 percent of 504 species of primates are threatened with extinction.
‘Ants are expert navigators, even walking backwards’
Despite their tiny size, ants are sophisticated navigators that can find their way even while walking backwards, and these skills could help inspire better robots, scientists say. The findings in this week’s edition of the journal Current Biology are based on a colony of desert ants that were studied to see how they navigated home while carrying pieces of a cookie.
India’s first GM food crop held up by lawsuit
India’s long-standing push to approve genetically modified food crops has been controversially delayed, after an environmental campaigner launched a lawsuit that accuses scientists of deceiving the public about the benefits of transgenic mustard. The claims are untrue, says Deepak Pental, a plant geneticist at the University of Delhi who has led research into the crop.
Moths take tiny cars out for a spin – CNET
We thought we’d seen everything with driving dogs , but now silkmoths are muscling in. Maybe they don’t know they’re doing it, but researchers from the University of Tokyo have used the insects to steer tiny cars.
Rats and cockroaches among thousands of pests found in NHS hospitals
Thousands of pests including cockroaches and rats have been found in NHS hospitals in each of the last five years as the cost of tackling them has spiralled, new figures show. Data obtained by the Press Association under Freedom of Information laws shows there were nearly 5,000 pest control call-outs by NHS trusts to hospitals in England in 2015/16 – equivalent to around 13 a day.
