Bats build mental maps to recognise surroundings

Bats build mental maps to recognise surroundings

The study proposes that template-based place recognition might underlie the sonar-based navigation known as echolocation that bats usually are known to use for navigating and finding food in the dark. 

A hearing aid that guides blind walk safely

A hearing aid that guides blind walk safely

A tech start-up, floated by a former Wipro geek, has innovated a smart hearing aid with sensors to make the visually challenged (blind) walk safely by avoiding objects on way.

Bats are fast decision makers

 Bats are capable of making ultra-fast decisions about how to attack their prey - or maybe even call off the attack and it takes only milliseconds, finds a new research.

Human echolocation can help blind 'see'

The ability to detect objects in the environment by sensing echoes from them is more than just a functional tool to help visually-impaired people, shows a study.

Bats change tactics when food is scarce

Bats change tactics when food is scarce

When food is scarce, bats change their tactics and turn more flexible in their echolocation behaviour.

Bats may help bolster radar technology

The natural ability in bats to navigate and track targets in the dark of night may help them develop a new and more effective radar or sonar system.

How bats use a compass to find their way at night

A European bat type can use the scatter patterns of sunlight to programme its internal compass for hunting after dark -- the first mammal known to do so, researchers said today.

Fossilized whale skull shows sonar existed 32 million years ago

Researchers have said that a fossilized whale skull found outside Charleston, South Carolina shows all the tell-tales signs that are related to echolocation.

Echolocation behind bats ruling nights

Bats rule the night skies due to the power of echolocation or reflected sound which gives the mammals an evolutionary edge over other nocturnal species, a new study has found.

Bats, dolphins evolved echolocation in same way

Scientists have found that there are certain genetic similarities between bats and dolphins and that the evolution of similar traits in different species.

Bats catch insects by sonar and not vision during twilight

Researchers have found that echolocation works better than eyesight, even under adequate light.

New technique lets blind people locate objects like bats

Blind and visually impaired people have the potential to use echolocation to determine the location of an object, according to new research.

A device to communicate with dolphins!

Scientists have developed a new dolphin speaker device which they say could help one talk with these remarkably intelligent mammals.

Bats, whales have surprisingly similar bio-sonars

Bats and toothed whales use surprisingly similar acoustic behaviour to locate, track, and capture prey using echolocation, the biological equivalent of sonar.
