What was the most useful invention of 2014?

Determining the "most useful" invention of 2014 can be subjective, as it depends on the criteria used to evaluate usefulness, such as impact, innovation, or practical application. Here are a few notable inventions from 2014 that had significant potential or impact:

Mangalyaan (Mars Orbiter Mission)

Developed by the Indian Space Research Organization, Mangalyaan was a groundbreaking spacecraft that successfully entered Mars' orbit in September 2014. This mission marked a significant achievement in space exploration and was recognized for its technological and scientific contributions14.

DNA Nanobots

An Israeli team developed DNA nanobots that could be injected into cockroaches and assemble themselves to perform medical functions, such as targeting specific cells. This innovation has potential applications in treating diseases like cancer and represents a major advancement in nanotechnology and medicine4.

Scallop-Shaped Robots

Researchers at Germany’s Max Planck Institute created tiny robots that could swim through the bloodstream, powered by an external magnetic field. These robots have the potential to repair tissue damage or transport medicine, offering new possibilities in medical treatment4.

Neurobridge Microchip

Developed by researchers at Ohio State University, the Neurobridge microchip helped a paralyzed man regain the use of his arm by stimulating muscles according to brain patterns. This innovation holds promise for treating various disabilities and enhancing the control of devices through brain signals4.

Each of these inventions has the potential to be considered the most useful depending on the context and the impact they could have on different fields such as space exploration, medicine, and technology. However, if we consider immediate and broad medical impact, the Neurobridge microchip and DNA nanobots stand out for their potential to revolutionize medical treatments and improve the quality of life for many individuals.
