Scientists create world’s tiniest thermometer using DNA

Scientists have created the world’s tiniest thermometer that is 20,000 times smaller than a human hair, using DNA structures that can fold and unfold at specifically defined temperatures.

The advance may significantly aid our understanding of natural and human designed nanotechnologies by enabling to measure temperature at the nanoscale, researchers said.

Over 60 years ago, researchers discovered that the DNA molecules that encode our genetic information can unfold when heated.

NASA to explore Saturn’s icy moons for alien life

NASA scientists have proposed deploying a robotic system to explore the exotic environment of the subsurface oceans of Saturn’s icy moons that may potentially harbour life.

Several concepts have already been studied to explore the subsurface oceans of Europa and Enceladus using autonomous underwater vehicles (AUVs).

However, access to subsurface ocean remains to be an outstanding challenge, researchers said.
