Your windows might soon be more than just portals through which your neighbours judge you. Researchers have developed a solar coating that can be added to ordinary glass, letting light pass through while harvesting energy. It works by guiding part of the sunlight into the edges of the window, where hidden solar cells soak it up. 

The team’s prototype managed to power a fan, and their models suggest that in real-world conditions, a window like this could concentrate sunlight 50-fold and cut the amount of silicon solar cells needed by 75%. Given the extortionate price of modern windows, it’s nice to know that soon they may in part pay for themselves. 

🧐 What's in it for me? One day soon these could help pay your electricity bill. Expect them first in offices and skyscrapers, then eventually in flats and homes, probably within the next decade.

AI is gluttonous. Every time you ask an LLM how to boil an egg, vast racks of GPUs somewhere heat up like a turbocharged toaster. Now though, light-powered AI chips may deliver 100x efficiency.

Researchers have built a chip that uses light instead of electrons when performing one of AI’s most energy-hungry tasks: recognising patterns. Instead of passing electricity through circuits, the chip converts data into laser beams, shines them through microscopic “flat lenses” to get the maths done before converting it back into digital data.

In essence, today’s AI chips analyse pictures by crunching through thousands of electronic steps to spot patterns like edges, shapes, and textures. The photonic chip does the same job far more elegantly: it simply shines light through tiny engineered lenses, letting the physics of the light itself handle the maths.

With any luck, inventions such as this may push energy prices back down, but more realistically, it’ll just mean a whole lot more AI. Expect this to hit data centres first where it could slash costs. After that, your AI native devices could incorporate to become significantly more efficient.

Heart attacks are normally blamed on poor diets, bad genes or an aversion to exercise. However, a Finnish-UK team suggests something else might be to blame: bacteria hiding in artery plaques. These microbes can lie dormant for decades before a viral infection or another trigger wakes them up, causing inflammation that can rupture the plaque and spark a heart attack.

If this proves correct, it could shift our understanding of certain heart diseases. Instead of just focusing on cholesterol and blood pressure, future treatments might target infections that set the whole process off in the first place.

🧐 What's in it for me? GPs may start prescribing antibiotics for heart disease instead of just statins. It’s still speculative and decades away from reality, but it could completely change the way we prevent cardiovascular problems (in a good way…)

Stanford scientists have reversed autism-like behaviours in mice after identifying a brain region that appears to be the culprit. It’s called the reticular thalamic nucleus and acts a bit like the brain’s bouncer, deciding which sensory information gets in and which stays outside shivering. In autism models, this region seems to get hyperactive, letting in all the wrong people and starting fights.

By damping down this activity (using drugs already being trialled for epilepsy) they were able to make autistic mice less twitchy, less repetitive and more sociable. They even reversed seizure susceptibility. The fact that the same treatment can induce autistic-like behaviours in normal mice by ramping up this region suggests they’ve found a major lever.

🧐 What's in it for me? This isn’t a cure, but it’s a roadmap. Given that existing epilepsy drugs already interact with these circuits, clinical testing could move faster than usual. Autism diagnoses have been rising steadily worldwide which makes the search for targeted treatments all the more urgent. Human treatments are still years off, but for families and patients, the direction of travel looks very promising.

Google’s quantum processor has done something for which physicists normally require piles of blackboards and a country-sized accelerator: it simulated a gauge theory, a mathematical framework that explains how particles interact and how invisible “strings” tether them together. 

In other words, the computer isn’t just computing, it’s poking at the same rules that built the universe. Watching these strings ripple, tighten, and snap in real time is like glimpsing nature’s backstage mechanics. It’s early days, but the implications are vast: quantum computers are becoming laboratories for reality itself, where we can test ideas about the fundamental fabric of matter, energy, and perhaps space-time.

🧐 What's in it for me? Unless your day job involves rewriting the universe, not much immediately. But in the long run, breakthroughs here could reshape industries from energy to pharmaceuticals. Expect ripple effects in the next 10–20 years.

Was There Life On Mars? 👽

NASA’s Perseverance Rover has discovered minerals in an ancient Martian lakebed that could be biosignatures (i.e. chemical clues of past life). The catch? Minerals like these can also form without life, so scientists are keeping the champagne on ice. Still, it’s the strongest suggestion yet that Mars was more than just a dusty desert a billion years ago.

To confirm, those for rock samples would need to be brought back to Earth, a mission pencilled in for the 2030s. Until then, Mars continues to play hard to get: giving us just enough evidence to stay interested, but not enough to confirm anything. It’s the longest-running cliffhanger in planetary science.

Until next time, stay curious.
