Scientists at The University of Manchester have created the world’s first ‘molecular robot’ that is capable of performing basic tasks including building other molecules.
The tiny robots, which are a millionth of a millimetre in size, can be programmed to move and build molecular cargo, using a tiny robotic arm.
Each individual robot is capable of manipulating a single molecule and is made up of just 150 carbon, hydrogen, oxygen and nitrogen atoms. To put that size into context, a pile of a billion billion of these robots would still only be the same size (volume/weight) as a few grains of salt.

According to India’s Frontline magazine, anecdotal evidence from Chennai, Hyderabad, Bangalore, Pune and other cities suggests that a number of large IT service companies are shedding thousands of jobs as artificial intelligence, automation and deep learning technologies replace humans.
Bangalore’s outsourcing businesses may be on the wane, but cities like Hangzhou may indicate its best course for the future.

As the U.S. government continues to pursue plans for a crewed mission to Mars, NASA has contracted with BWXT Nuclear Energy Inc. of Lynchburg, Virginia, to advance concepts in Nuclear Thermal Propulsion (NTP), which could drastically reduce travel times to Mars.
This is part of NASA’s Game Changing Development Program, which takes ideas from academia and industry as well as NASA and other government programs, to advance new approaches to space technologies to accommodate the changing needs of U.S. space efforts.
NTP is not a new concept, but it was abandoned in 1972 when plans for a Mars mission were shelved. NASA conducted ground tests since 1955 to determine the viability of NTP and has occasionally been revisited as a conceptual part of Mars mission feasibility studies.

The work, published in the March 8 issue of Science, finally proves that a single anti-aging enzyme in the body can be targeted, with the potential to prevent age-related diseases and extend lifespans.
The paper shows all of the 117 drugs tested work on the single enzyme through a common mechanism. This means that a whole new class of anti-aging drugs is now viable, which could ultimately prevent cancer, Alzheimer’s disease and type 2 diabetes.
“Ultimately, these drugs would treat one disease, but unlike drugs of today, they would prevent 20 others,” says the lead author of the paper, Professor David Sinclair, from UNSW Medicine, who is based at Harvard University. “In effect, they would slow aging.”
