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.
A solar-powered airplane landed in California on Saturday, completing a risky, three-day flight across the Pacific Ocean as part of its journey around the world.
Pilot Bertrand Piccard landed the Solar Impulse 2 in Mountain View, in the Silicon Valley south of San Francisco, at 11-45 p.m. following a 62-hour, nonstop solo flight without fuel. The plane taxied into a huge tent erected on Moffett Airfield where Mr. Piccard was greeted by project’s team.
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.
Not content with only saving people from burning buildings, this Pakistani firefighter has also spent decades saving children from illiteracy–and entrenched poverty–by teaching thousands to read, write, and do math.
Every workday for 30 years, Mohammed Ayub has left his job at an Islamabad fire department and set up a makeshift classroom in a city park.
And every day, hundreds of kids wait for “Master Ayub” to arrive on his bicycle so they can learn.
