You’d think that existing exclusively within the human body would give way to a complete knowledge of the organs hidden within. Instead, we’re constantly discovering new parts of the weird and glorious biological machine we each call home. The latest in these discoveries are the “tubarial glands,” a pair of small organs responsible for producing saliva.
We may think we invented mathematics but we actually only discover it. It’s the immaterial underpinning of material nature.
Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them.
“M-PESA”: that is a name in global fintech history that can never be erased. Not that anybody would want to. Forever it will be the perfect example of a viable financial ecosystem based on rules unthinkable before. A living masterpiece that was created by a mosaic of unique circumstances, choices and risks taken at a particular time and place, and that continues to evolve in the changes it brought to the country.
Since I’m neither a local, nor deeply involved with the African markets (yet), I would not dare to simply impose my DIY analytics on my readers. Instead, I invite you to listen to my conversation with M-PESA’s own Kevin Amateshe reflecting on Kenya’s digital financial services space, M-PESA’s role, the past, present and future: https://youtu.be/QlZuKwnsAS4
Chip foundry Taiwan Semiconductor Manufacturing plans to start mass production of chips using its 3-nanometer process technology.
This year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution”—a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement. A large-scale and fully functional quantum network is the holy grail of quantum information sciences. It will open a new frontier of physics, with new possibilities for quantum computation, communication, and metrology.
One of the most significant challenges is to extend the distance of quantum communication to a practically useful scale. Unlike classical signals that can be noiselessly amplified, quantum states in superposition cannot be amplified because they cannot be perfectly cloned. Therefore, a high-performance quantum network requires not only ultra-low-loss quantum channels and quantum memory, but also high-performance quantum light sources. There has been exciting recent progress in satellite-based quantum communications and quantum repeaters, but a lack of suitable single-photon sources has hampered further advances.
What is required of a single-photon source for quantum network applications? First, it should emit one (only one) photon at a time. Second, to attain brightness, the single-photon sources should have high system efficiency and a high repetition rate. Third, for applications such as in quantum teleportation that require interfering with independent photons, the single photons should be indistinguishable. Additional requirements include a scalable platform, tunable and narrowband linewidth (favorable for temporal synchronization), and interconnectivity with matter qubits.
As a general rule, if you want sight, you need light. You’re only reading this right now thanks to the light from your screen being beamed onto your retinas, converted into electrical signals, and sent up the optic nerve for your brain to interpret as a bunch of words and images.
But what if you could see things without all that rigamarole? It might sound impossible – perhaps even counter to the very definition of sight – but thanks to the bizarre world of quantum mechanics, it’s actually perfectly possible.
“Since the inception of quantum mechanics, the quest to understand measurements has been a rich source of intellectual fascination,” notes a new paper published this month.
A close-knit pair of newborn stars are kicking up shock waves — and seeding the material of their future planets with organic molecules.

It’s as good a time as any to discuss the implications of advances in artificial intelligence (AI). 2022 saw interesting progress in deep learning, especially in generative models. However, as the capabilities of deep learning models increase, so does the confusion surrounding them.

What were the first moments of the Universe like? It’s a mystery that scientists have been trying to unravel for decades. The ALICE collaboration at CERN is a specialist in the subject: this detector (A Large Ion Collider Experiment) was designed to study quark-gluon plasma, a phase of matter that would have existed just after the Big Bang. And the team recently succeeded in recreating and characterizing this very first hypothetical material, using the Large Hadron Collider (LHC).
