How to Survive Without Air
The naked mole-rat shows off its breath taking super-powers. Also, scientists have created an artificial layer of the eye, the retina, and volcanoes can now be spotted from space
The naked mole-rat never ceases to amaze. A new study shows that when it gets stuffy in their underground burrows, this mouse-sized wrinkly mammal is able to metabolise fructose - just as plants do - and by this bypass the need for oxygen for up to 18 minutes.
In a new study scientists have created an artificial retina. The retina is a light-sensitive layer of the eye which is essential for sight. The artificial retinas are able to mimic the abilities of living tissue, reacting to light and electrical signals. In the future, scientists hope that these retinas could save the sight of many.
Virtual reality (VR) is not only a fun gimmick for gamers, but could be used to train dentists in dental surgery. Our reporter Marnie Chesterton visits the VR World Congress in Bristol in the United Kingdom and tries out the technology and discovers first-hand the all too real experience of dental surgery.
Lastly, with 800 million people living near a volcano, spotting eruptions in advance can be crucial. We talk to the scientists working on the technology that allows us to spot them from space with satellites. And, reporter Anand Jagatia heads to Iceland which homes the volcano Eyjafjallajökull, which caused disruption to the air space back in 2010.
