Google Maps “immersive view” is the ultimate graphics mode for Google Maps
May 2022, Ars Technica
There are simulated cars that drive through the roads, and birds fly through the sky. Clouds pass overhead and cast shadows on the world. The weather is simulated, and water has realistic reflections that change with the camera. London even has an animated Ferris wheel that spins around. Google can't possibly be tracking things like the individual positions of birds (yet!), but a lot of this is real data. The cars represent the current traffic levels on a given street. The weather represents the actual weather, even for historical data. The sun moves in real time with the time of day.

NeuroMechFly: A digital twin of Drosophila
May 2022, phys.org
It's not an actual robot but a model:
EPFL scientists have developed a digital model of the fruit fly, Drosophila melanogaster, that realistically simulates the movements of the animal. The twin is a big step towards reverse engineering the neuromechanical control of animal behavior, and developing bioinspired robots.Morphologically realistic biomechanical model and a kinematic database of real limb movements of the fly from deep-learning pose estimation motion-capture softwareA model that integrates what we know about the fly's nervous system and biomechanics to test if it is enough to explain its behavior."Drosophila is the most commonly used insect in the life sciences.

Why you may have a thinking digital twin within a decade
Jun 2022, BBC News
Dr Steve Levin's daughter was born with congenital heart disease, and a few year's back, when she was in her late 20s and at high risk of heart failure, he decided to recreate her heart in virtual reality so it can be tested and analysed, allowing surgeons to play out a series of "what if" scenarios for the organ, using various procedures and medical devices.US software firm Nvidia runs a platform called Omniverse to create digital twins. One of its most ambitious projects is to build a digital doppelganger of the Earth, called Earth-2.In March this year, the European Commission, in conjunction with the European Space Agency among others, announced its own plans to make a digital twin of the planet, dubbed Destination Earth.
Algorithm predicts crime a week in advance, but reveals bias in police response

Just here for the paraself (shoutout to Ted Chiang)
"We created a digital twin of urban environments. If you feed it data from happened in the past, it will tell you what's going to happen in future.

Twin physically unclonable functions (PUFs) based on carbon nanotube arrays to enhance the security of communications
Jul 2022, phys.org
"To achieve a low-cost and hardware-based secure communication, we introduced a new technology, twin physically unclonable functions (PUFs)," Zhang said."The basic idea behind PUFs is to utilize random physical imperfections existing in a physical entity caused by the fabrication process, and these imperfections cannot be predicted or cloned, even by the original manufacturer."Due to their unique design, PUF devices are unclonable and unpredictable. This makes them incredibly effective at generating safe secret keys for encryption.
