A professor of Physics at Madurai Kamaraj University has come up with a prototype of a unique respiratory mask that can pick up oxygen from the atmosphere for the wearer.
The ventilator-cum-respiratory mask ensures more than 40% of atmospheric oxygen is available within the mask.
Called LIDS-VR mask, it contains sensors to regulate the level of oxygen. The device contains a nanomaterial that can absorb oxygen. It requires energy to release the oxygen for the wearer.
The respirator could be used when a sick patient is waiting for ambulance or by festival shoppers at a heavily crowded mall. This is particularly helpful for asthmatic persons. It can also be used in aeroplanes.
A well-preserved Ice Age woolly rhino with many of its internal organs still intact has been recovered from permafrost in Russia’s extreme north.
It’s among the best-preserved specimens of the Ice Age animal found to date. The carcass has most of its soft tissues still intact, including part of the intestines, thick hair, and a lump of fat. Its horn was found next to it.
Recent years have seen major discoveries of mammoths, woolly rhinos, Ice Age foal, and cave lion cubs as the permafrost increasingly melts across vast areas of Siberia because of global warming.
Scientists dated the carcass as anywhere from 20,000- to 50,000-years-old. More precise dating will be possible once it is delivered to a lab for radiocarbon studies.
