Chishuru, a male African elephant, indicates a target scent during trials.
Elephants have the highest count of olfactory receptor genes of any species tested to date. This suggests that they may be the best smellers in the animal kingdom.
Lassa fever in several Nigerian states is being spread by rats.

Lassa outbreaks are becoming more widespread in Nigeria but have not been given national emergency status like Ebola.
Gene drives aim to deliberately spread bad genes when invasive species such as mice reproduce.

Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
In many parts of Africa rodents often cause crop losses.
Agricultural pests are one of the key factors affecting small holder farmer production. Focus is normally put on invertebrate pests, but rodents can do severe damage to crops as well.
Animals that group together to fight off evolutionary pressure may actually evolve faster.
Feral cats are a major driver of global biodiversity loss, contributing to 26% of bird, mammal and reptile extinctions.
Cats, rats, foxes and other mammal predators have been implicated in 60% of the world's animals extinctions.

Rats foul our food, spread disease and damage property, but we know very little about them. A biologist explains how he tracks wild rats in New York City, and what he's learned about them so far.
Rats are true natives of our cities.

Rats have lived with us for thousands of years.

An expedition to the Solomon Islands to investigate rare monkey-faced bats and giant rats will help preserve these remarkable species.
Uncollected rubbish provides food and shelter for rodents which can spread plague if they pick up the bacteria.
Plague, one of the deadliest diseases in the world, has been reported in several African countries in the past decade.
We all know that stress can wreak havoc on your health but what does it do to your genes?
Even in a dreary office, by understanding how your brain works you can change how it feels to be there.
In many of the workplaces I visit as a neuroscientist, stressed workers behave much like addicted lab rats. But you don't have to quit the rat race to start feeling better at work.
Mustela erminea), feral cats ( Felis catus), red foxes ( Vulpes vulpes) and black rats ( Rattus rattus) are invasive predators in different parts of the world.

Research published this week shows saving wildlife is much more complicated than killing introduced predators. Killing predators often doesn't work, and is sometimes actually worse for native wildlife.
Just ask a cab driver - they’ve got that map in their head.
When we figure out how places connect geographically, local maps in the brain join into a single, overarching map.
“Remember, we’re all in this together.”
Altruistic behaviour is not just for humans, lab rat behaviour test shows.
Memories can be selectively removed in rats with an altered memory reactivated in its place, according to a new study by…
Ducking for cover.
Declining numbers of zebra, antelope and other big grazers cause rodent populations to rapidly increase, a new study has shown. Published in the Proceedings of the National Academy of Sciences, Hillary…
When it comes to thinking about disease, rats are usually thought of as vermin that carry plague and pestilence. But what about rats being used to sniff out diseases such as tuberculosis in people’s saliva…
Malaria parasites that infect West African bats are closely related to parasites which are used to model human malaria in…
From street scourge to lab hero: rats have provided us with significant insights into human diseases and disorders.
Our series, Animals in Research, profiles the top organisms used for science experimentation. In this instalment, we look at the original lab rats: Rattus norvegicus. Rats have a long history in medical…
