No more money for either of them until we fix this.

Scientists have developed an eco-friendly battery made from tree pulp, offering a sustainable alternative to traditional batteries.

Crafted from tiny wood fibers, these batteries are strong, flexible, and conductive, powering small devices like drones, fitness trackers, and lights without heavy metals, plastic parts, or waste.

They biodegrade in under two months, enriching soil harmlessly after use. Free of toxic metals like lithium or cobalt, they eliminate pollution, fire hazards, and electronic waste, making them ideal for dissolvable health patches, eco-friendly GPS devices, and smart wearables.

While still in testing and optimized for low-power applications, their 90% energy efficiency in lab trials has spurred interest, with startups like VTT Technical Research Centre racing to scale production.

This innovation promises to revolutionize battery use and disposal, though challenges like cost and energy density for high-power devices remain, fueling rapid development efforts.

🤯 SCIENTISTS JUST 3D-PRINTED WOOD FROM FLOWER CELLS - NO TREES HARMED!

This sounds like science fiction, but it's happening RIGHT NOW: MIT researchers have figured out how to grow actual wood from zinnia flower cells in a lab, then 3D-print it into any shape they want. Tables, chairs, even entire buildings - all made from flowers, not forests!

THE MIND-BLOWING BREAKTHROUGH:

Researchers used cells from Zinnia elegans, the common zinnia flower, to print custom-shaped wood segments. By applying hormones to the growing sample, the researchers managed to adjust a wide range of variables — like strength, density, and stiffness. They literally program the wood's properties like coding software - want it harder? Softer? Different grain? Just change the hormone recipe!

FORAY BIOSCIENCE MAKES IT REAL:

The company uses plant cell culture, materials science, and tissue engineering to produce wood products without cutting down trees, and raised $3M in 2024 to scale up production. Just as lab-grown meat has proven its commercial viability, Foray is developing a platform to bioengineer an expansive range of plant-based products.

THE VIRAL MOMENT:

We can now 3D print as much wood as we want without cutting down a single tree. Which is a fairly big deal, when you consider that the forestry and logging market was estimated at $285.2 billion in 2021, and is expected to reach a revised size of $438.5 billion by 2026.

CUSTOM WOOD ON DEMAND:

The team experimented with different levels of the hormones, and found that lower levels led to lower density material, with rounded, open cells. Higher levels, meanwhile, grew smaller, denser structures that were more stiff, thanks to the increased growth of the organic polymer lignin. It's like having a wood factory that takes orders: "I'll have one oak-strength beam, one pine-light panel, and one mahogany-dense tabletop - all from the same flower cells!"

WHAT THIS MEANS:

Imagine never cutting down another tree for furniture, houses, or paper. The concept is similar to lab grown meat. Scientists create structures made of plant cells that mimic wood, but without needing to chop down forests in the process. The wood-like plant tissue is grown indoors without soil or sunlight.

THE FUTURE IS NOW:

Foray's process involves extracting live cells from the leaves of plants such as the black cottonwood, a popular species for making fiber products, then growing them into whatever wood product you need. Your next dining table could be made from a single leaf!

This isn't just saving trees - it's rewriting the rules of manufacturing. The age of growing materials instead of harvesting them has officially begun! 🌸➡️🪵

Spain built a skyscraper that grows food, makes energy, and purifies air — all at once

Rising from the skyline of Valencia is a building that doesn’t just house people — it breathes, grows, and cleans. The “Verdetorre” (Green Tower) is Europe’s first fully self-sustaining biotecture skyscraper, designed to function like a living organism within the city.

Each floor of the tower contains layers of hydroponic gardens that produce fresh fruits, vegetables, and herbs — enough to feed up to 500 residents. Integrated solar panels line the outer surfaces, and wind ducts channel airflow through micro-turbines embedded in the walls, generating electricity 24/7.

But the real innovation lies in the tower’s “skin” — a living façade made of algae tubes, mosses, and air-filtering membranes. This porous outer shell actively captures CO₂, filters pollutants, and humidifies the air, creating a bubble of clean, oxygen-rich atmosphere around the tower.

The tower collects rainwater through slanted window awnings, channels it into underground tanks, and filters it for drinking and irrigation. Wastewater is processed on-site through a bioreactor basement that uses microbes to clean and recycle every drop.

Inside, natural airflow, smart lighting, and AI climate control allow residents to live in full comfort without ever connecting to an external grid. Each apartment gets its own energy dashboard and food harvest log.

It’s more than a building. It’s an ecosystem stacked vertically — architecture as a living environment.
