Researchers have developed a light-weight sensor system that can be carried by small insects like a moth to destinations that are dangerous or too small for humans to reach.
Once it reaches the destination, researchers can send a Bluetooth command to drop the sensor from its perch. The sensor is held on the insect using a magnetic pin surrounded by a thin coil of wire.
As soon as a researcher sends a wireless command to release the sensor, it creates a current through the coil that makes the magnetic pin to pop out the sensor.
The researchers believe that they can use this to create a network of sensors in a study area. This includes scattering sensors across a forest or farm to track them. They expect that this system can be deployed in different locations, including environmentally sensitive areas.
A team of researchers have reported a new species of perennial woody herb of the genus Lepidagathis from the northern laterite plateaus of Kasaragod district in Kerala.
The plant was spotted during field explorations in the region. With its discovery, the number of species of the genus Lepidagathis (family Acanthaceae) found in India has risen to 34.
To date, eight species of the genus Lepidagathis and three varieties have been reported from Kerala, of which four are endemic to the Western Ghats.
An erect woody herb that grows to a height of 50-100 cm, Lepidagathisananthapuramensis is characterised by a hairy and branched stem, thick and woody rootstock, hairy leaf veins, and flowers clustered on one side of the inflorescence.
