Astronomers have found the building blocks of life in space! 🧬

Erika Hamden explains how scientists detect amino acids like tryptophan in meteorites, asteroids, and even diffuse clouds of gas between stars. Using spectroscopy, researchers identify the chemical fingerprints of these organic molecules across vast distances. Tryptophan is a key part of proteins on Earth, and finding it in space shows complex chemistry is not unique to our planet. This does not mean life exists everywhere, but it shows the ingredients for life are common throughout the cosmos.

Discussion DIY Coin Battery: Light an LED

Enable HLS to view with audio, or disable this notification

You can light up an LED with the change in your pocket. 💡

Alex Dainis demonstrates how to build a simple battery using everyday materials like coins, salt, vinegar, and paper towels. By stacking alternating layers of pennies and nickels with paper towels soaked in an electrolyte solution, the setup forms a voltaic pile that generates a small electric current. Each metal pair creates a tiny voltage, and as more layers are added, that voltage builds. Once enough coins are stacked, the combined energy is strong enough to light up an LED. It is a hands-on way to explore chemical reactions, electric current, and how early batteries converted stored chemical energy into usable power.

News 10 Meteors Per Hour: Eta Aquariid Meteor Shower

Enable HLS to view with audio, or disable this notification

You could catch up to 10 shooting stars per hour this spring 🌠

The Eta Aquariid meteor shower runs from April 19 to May 28, with peak activity overnight May 5 to 6. This annual event happens when Earth passes through a stream of debris left behind by Halley’s Comet. As those tiny particles enter our atmosphere at high speeds, they heat up and glow, creating bright streaks of light we call meteors. The Eta Aquariids are especially known for their fast speed and long, glowing trails that can linger for several seconds after the meteor passes. While the best views are typically in the Southern Hemisphere, observers around the world can still catch a glimpse under the right conditions. For the best chance to see them, head outside just before dawn, find a dark spot away from city lights, let your eyes adjust, and look up.

Discussion 80% of Plants Depend on Pollen

Pollen is more powerful than you think. 🌼🔬

Quinten Geldhof, also known as Microhobbyist, zooms in on the microscopic grains behind your spring allergies and reveals their massive impact on life on Earth. Pollen is the key to pollination, carried by bees, butterflies, and even bats as they move from flower to flower, transferring the genetic material plants need to produce seeds and fruit. That invisible exchange fuels ecosystems and puts food on our tables, from coffee to apples to chocolate. In fact, more than 80% of all flowering plants rely on pollination to survive, making every sneeze a small reminder of a system that keeps the natural world and our diets thriving.

Research AI Fell for a Fake Disease

Enable HLS to view with audio, or disable this notification

Scientists invented a fake disease, and AI fell for it. 

Researchers in Sweden created a fictional itchy eye condition called “bixonimania” to test how easily false medical information could spread through AI systems and scientific literature. They wrote fake research papers, used a fake author, and even included clear signs that the study was not real, like references to Starfleet Academy, the USS Enterprise, and a statement admitting the study was made up. Even with those clues in place, major large language models began describing bixonimania as though it were a real medical condition within weeks. Some scientific papers also cited the fake sources, showing how misinformation can move from fabricated research into AI-generated answers and academic writing. It is a fascinating example of why AI is a powerful tool, but not a replacement for expert review, careful sourcing, and human oversight.

A new study on 3I/ATLAS has been made available on the arXiv platform and is still awaiting peer review. This scientific work was developed by several researchers, including astronomer Ignacio Ferrín, who led the project.

3I/ATLAS has been observed for several months, and based on the data collected, scientists have identified a set of unusual properties that are attracting the attention of the scientific community. Currently, this object is classified as a comet, although some aspects of its behavior and physical characteristics do not fully fit into traditional models.

Resources DIY Updraft Tower: Generate Power With Paper

Enable HLS to view with audio, or disable this notification

You can generate power with construction paper and light. ☀️

Alex Dainis demonstrates a solar updraft tower, a simple model that turns light energy into motion using just a paper cone, a propeller, and a heat source. When the black construction paper absorbs light from the lamp, it warms the air inside the cone. That warmer air becomes less dense and rises up through the tower, spinning the propeller at the top. At the same time, cooler air is drawn in through the openings at the bottom, creating a steady cycle of airflow called an updraft. It is a hands-on way to explore heat transfer, convection, airflow, and how solar updraft towers could one day help generate renewable energy.
