Computer chips (the tech kind, not the potato kind) normally work by moving electrons, tiny particles that carry electricity. Wave Photonics, a company based in Cambridge, England, is designing chips that use photons instead. Photons are particles of light.
Chips that use light can carry more information while using less energy. That makes them especially useful for AI data centers, the huge buildings full of computers that power tools like chatbots, and for quantum computers. They're part of a wider push to make quantum technology smaller and practical enough to build in large numbers. The industry is growing so quickly that Wave Photonics plans to double its staff.
Quantum computers are hard to build, but they could be worth the effort. They use the strange rules of quantum mechanics, the science of how the tiniest particles behave. That lets them tackle certain problems in a completely different way from ordinary computers. For some tasks, they could one day be far faster than even today's most powerful machines.
In the early days of the industry, governments were cautious and mostly bought from companies with a proven track record. Now they're more willing to take chances on newer companies.
If quantum computing keeps growing, it could eventually change fields like medicine, by helping scientists design new drugs, and finance. It could also become a bigger part of the economy.
Forests store huge amounts of carbon, likely hundreds of billions of tons. One metric ton is about 2,200 pounds, so hundreds of billions of tons is... let's just say it's a lot. Because trees pull carbon dioxide out of the air and lock it away, forests play a major role in controlling Earth's climate.
To figure out how much carbon a forest holds, scientists can measure individual trees, like how wide the trunk is and how tall the tree grows. But nobody can take a tape measure to millions of square miles of forest, and "a whole bunch" isn't a scientific measurement.
That's where new technology comes in. In 2025, the European Space Agency, which runs space missions for a group of European countries, launched a satellite called Biomass. It uses radar with extra-long wavelengths. The longer the wavelength, the more easily radar can pass through leaves and small branches and pick up bigger things, like trunks and large branches, which hold most of a tree's carbon.
Most earlier satellites, like many launched by NASA, the U.S. space agency, are optical. They work like cameras, capturing sunlight reflected off the treetops. That's useful for seeing where forests are, but it mostly shows the top layer. Radar can reveal what's underneath. It can help scientists estimate how much wood a forest holds, spot deforestation, and study flooded forests that are hard to reach. Scientists then check the satellite data against measurements taken from planes and on the ground.
Another tool is LiDAR, short for Light Detection and Ranging. It sends out pulses of laser light and measures how long they take to bounce back, building detailed 3D maps of forests. Some are precise enough to show individual twigs and leaves. LiDAR isn't new, but it produces enormous amounts of data. Artificial intelligence is now making that data much faster to process, turning LiDAR into a more practical tool for studying forests.
Over the next few months, scrolling on your phone may look a little different. That’s because Meta, the company behind Facebook and Instagram, has been facing more pressure over claims that its platforms harm young people, and both citizens and the legal system have been demanding a change that has landed Meta in a lawsuit.
A judge in New Mexico did not hold back on criticizing harmful content, declaring Meta’s platforms a "public nuisance" and comparing the company to a factory creating toxic pollution. Yikes. The court also called out Meta for design features like infinite scroll, notifications, and recommendation algorithms that encourage people to stay online longer.
Meta was ordered to put a whopping $567 million into a five-year fund addressing harms. That’s on top of $375 million awarded earlier in the same case! But believe it or not, that’s not a ton of money for the company. The important part is not the money itself, but the indication that people are demanding change and getting companies to listen. Meta isn’t just being asked to pay a fine but to actually make changes, like restricting contact with adults, limiting notifications, and placing limits on how long people under 18 can spend on Facebook and Instagram.
Meta strongly disputes the ruling and plans to appeal, but the case has already set a larger question into motion about if tech companies should be held responsible not only for what users post but also how their platforms are designed.
