Watch Nanobot Carry Lazy Sperm to Fertilize Living Eggs

A sperm’s task may appear straightforward; after all, all it needs to do is swim to an egg and insert genetic material. However, in some cases, a healthy sperm’s inability to swim may result in infertility, which affects around 7 percent of all males.

This condition is called asthenozoospermia, and there is currently no cure. However, one study conducted in 2016 and published in the journal Nano Letters has set the example for what could be possible in the future: A team of researchers from the Institute for Integrative Nanosciences at IFW Dresden in Germany developed tiny motors that can make sperm swim better as they make their way to an egg, essentially acting as a taxi.

These so-called “spermbots” basically consist of a tiny micromotor, which is basically a spiraling piece of metal that wraps around the sperm’s tail. Serving as an “on-board power supply”, the motor navigates the sperm via a magnetic field, helping the sperm swim to the egg with ease. When the sperm makes contact with the egg for fertilization, the motor slips right off, and the magnetic field doesn’t harm any of the cells involved, making it ideal for usage on living tissue, according to the researchers.

Scientists propose putting nanobots in our bodies to create ‘global superbrain’

A team has proposed using nanobots to create the ‘internet of thoughts’, where instant knowledge could be downloaded just by thinking it.

An international team of scientists led by members of UC Berkeley and the US Institute for Molecular Manufacturing predicts that exponential progress in nanotechnology, nanomedicine, artificial intelligence (AI) and computation will lead this century to the development of a human ‘brain-cloud interface’ (B-CI).

Writing in Frontiers in Neuroscience, the team said that a B-CI would connect neurons and synapses in the brain to vast cloud computing networks in real time.

Such a concept isn’t new with writers of science fiction, including Ray Kurzweil, who proposed it decades ago. In fact, Facebook has even admitted it is working on a B-CI.

However, Kurzweil’s fantasy about neural nanobots capable of hooking us directly into the web is now being turned into reality by the senior author of this latest study, Robert Freitas Jr.
