But while insects command their colonies with pheromones , the naked mole-rat queen uses physical aggression to keep their groups digging tunnels, foraging, and defending entrances.

Living underground in complex networks of tunnels in East Africa, their thermally stable environment means that a few orientation-aiding bodily hairs and facial whiskers are all they need.

Naked Mole-Rats

Naked mole-rats use their powerful jaws and very large incisors to dig through hard-packed soil. If agriculture expands into their range, they could become targeted as pests. John Smith does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. Research into the ageing processes of naked mole-rats is only in its infancy, but could have multiple implications for treating ageing-related conditions in humans. Napping mole-rats often sleep on their backs, upside down. Mole-rats eat the underground parts of plants.

Naked Mole-Rats: Blind, Naked, and Feeling No Pain.

Many respiring animals cramped together in unventilated burrows elevates CO2 levels, high enough to cause acidosis pain, and depletes O2 concentrations low enough to kill other mammals. Researchers identify changes to a pain receptor and to an ion channel that appear to enable the rodents to colonize otherwise inhospitable burrows. Their teeth can operate independently. This is true of sensory systems as well e. Naked mole-rats can be up to twice as heavy, so might be expected to live four to six years, but can actually survive for more than 30 years in captivity. Broadly speaking, a larger body equals longer life in mammals. Not content with just being immune to cancer, naked mole-rats are also impervious to some normally agonising chemical stimuli, such as capsaicin the substance that makes chilli peppers taste hot and acid what gives lemon juice and vinegar their kick.

Research into the ageing processes of naked mole-rats is only in its infancy, but could have multiple implications for treating ageing-related conditions in humans. These features may be a result of this species' "extreme subterranean lifestyle" that combines living underground and living in large colonies. Click through the PLOS taxonomy to find articles in your field. The way naked mole-rats mate and socially organise is more akin to certain insect species than to mammals. This could be extremely useful for cancer and arthritis sufferers, for whom build-ups of acid in body tissue can be a major contributor to chronic pain. The molecule responsible for insensitivity to acid in mole-rats also plays a role in human genetic conditions that drastically alter pain perception , and as a result of this convergent research, potential painkillers targeting this molecule have made it into clinical trials in humans.
