Inspired from bacteria, this is a Nobel-prize-winning technology which allows us to do genome editing very precisely. It's already being used in trials and early results look promising.

Researchers have been able to create robots from stem cells taken from frogs, allowing them to evolve on their own using AI and machine learning.

Researchers in Japan have developed software which can not only decode brainwaves, but also interpret them and offer us a visual representation of those thoughts. This was done using deep neural networks and it worked with a pretty good level of accuracy.

One day this could be used to recreate images straight from memory.

In an accidental discovery, Dutch scientists found a new organ behind the nose: a new type of salivary gland. It is a pretty hard to access area, so it explains why it took so long to find it.

NASA has detected that marsquakes (earthquakes, but on Mars) are rather regular and that there is a hum sound present on the surface of Mars, speculated to be caused by seismic activity and the sounds of the atmosphere. It falls outside the range of human hearing, but it's similar to the hum present on Earth, about which we don't know too much, either.

X-ray may sound creepy, but the tech definitely has its uses. Researchers at MIT have developed RF-Pose, using AI and radio signals to track someones' movement in the next room.

The ocean is huge and we're still finding new stuff out there. Recently, researchers have found a giant reef near the Great Barrier Reef. It is surprisingly large, at over 1.5km long (1.9 miles) and 500m tall (1640 feet).

2021 saw several extreme weather events pointing towards climate change. A recent reports claims that even if we cut emissions right now, we've passed the point of no return.
