As more and more products are manufactured via 3D printing, the potential for 3D-printed counterfeit versions rises accordingly. With that in mind, scientists have devised a method of ensuring that a printed item is the real thing, by building an "exploded" QR code into it.

Don't like the idea of a stranger finding out who you are, based on a photo? Thanks to the facial recognition systems used by social media sites, it's becoming increasingly possible. Scientists decided to do something about it, by turning a couple of AI systems against one another.

Have you ever said of a person, "You can see it in the way they walk"? Well, if it was their identity that you were referring to, then you were right. To that end, scientists have now created an artificial intelligence-based system that identifies people via their footsteps.

There's a relatively new way of determining what types of animals are present in an area – check the environment for their cast-off DNA, known as environmental DNA (eDNA). Next month, scientists will be using the technique in an effort to prove or disprove the existence of the Loch Ness monster.

When it comes to determining a person's eye, hair and skin color based on a DNA sample, scientists typically need to compare that evidence sample to an existing reference sample. That's reportedly no longer the case, however, if they're using the new HIrisPlex-S DNA test system.

Poachers typically hunt at night, which is why drone-mounted infrared cameras are being used to spot them. The problem is, it can be difficult to tell humans from animals in the videos. Scientists from USC are making the job easier, using artificial intelligence.

Smartphones are everywhere these days, packed with apps designed to make everyday life plain easier. Finland's Trafi is looking to tap into this ubiquitous nature so that drivers no longer need to carry a plastic driving permit, instead using a digital version accessed from within an app.

Even if some shady character were to get hold of your smartphone, it wouldn't do them much good if they didn't know your PIN … right? Well, researchers have created a system that correctly guesses a phone's PIN, based solely on information provided by its sensors.

Sorry, but your smartphone's camera isn't perfect. Its sensor contains flaws, which show up in its photos as imperfections known as photo-response non-uniformity (PRNU). Because each phone has its own unique PRNU pattern, scientists have proposed that it could be used as a form of identification.

When you're studying wildlife, it's important to have a way of differentiating between individual animals. With that in mind, scientists have discovered that bats can be told apart via their unique "wing prints."
