“Economics” is the science that studies how societies allocate their limited resources to satisfy their unlimited wants and needs.

In economics, specifically when discussing investments, if you had invested $100 in Intel stock 27 years ago, today you would still have just $100.

Termites of the species *Neocapritermes taracua* from French Guiana have a unique defense mechanism where they "explode" to protect their colony. These termites carry toxic "backpacks" containing the BP76 enzyme, which remains in a stable form until mixed with secretions during a threat. The enzyme's copper-based structure and sugar molecules keep it stable until needed. Once triggered, the explosive reaction releases a deadly toxin, immobilizing or killing attackers, though the termite itself perishes in the process.

Scientists have made progress in uniting general relativity and quantum physics, two theories that traditionally clash. A new approach considers gravity as an "emergent" phenomenon, arising from quantum interactions rather than a fundamental force. This breakthrough could potentially lead to a unified theory of quantum gravity, bridging the gap between our understanding of the cosmos at both massive and tiny scales.

Scientists in the U.S. have made biological tissues of live mice transparent using a solution of the dye tartrazine, which absorbs light. The dye was applied to the shaved scalp of the mouse, allowing researchers to visualize brain blood vessels with laser speckle contrast imaging. The solution also made the mouse's abdomen transparent, enabling direct observation of internal organs like the liver, intestines, and bladder. Remarkably, the effect is reversible by simply washing off the solution with water.

Symphonic Labs has developed a new Mac app that allows users to silently mouth words, and the app translates the movements into text. It currently works only with English and is an exciting tool for privacy-conscious users or even for spies, as it enables nearly silent speech recognition. The app reads lip movements and converts them into written text without the need for actual vocalization.

A clear illustration: how the brain heals the heart. Essentially, this image represents a prototype of a new kind of medicine.

We see the hearts of mice 15 days after a heart attack. The ones on the right are significantly better preserved — they have more cardiac tissue and less fibrotic tissue. What’s the reason? The mice on the right had daily stimulation of a specific brain area: dopamine neurons in the ventral tegmental area (VTA). This reduced inflammation and enhanced healing in the heart. It also affected the liver, which began producing more of a protein that helps form new blood vessels in the damaged heart tissue. No direct treatment was applied to the heart itself; only brain cells were activated.

Of course, mice are not humans, and it’s important to remember this. However, there is reason for optimism, as this approach doesn’t depend on the differences in molecules, genes, and so on.

A single teaspoon of a neutron star would weigh around six billion tons on Earth! Neutron stars are incredibly dense remnants of supernova explosions, packing more mass than our Sun into a sphere only about 20 kilometers across.

Scientists from the Ocean University of China have reconstructed Earth’s plate tectonics over the past 1.8 billion years.

They’ve condensed this vast timeline into an animation just one minute long! The animation showcases the movement of continents over nearly half of our planet’s history.

Around 200 million years ago, when dinosaurs roamed the Earth, Gondwana merged with North America, Europe, and Northern Asia to form the supercontinent Pangaea. Both Pangaea and Gondwana were composed of even older tectonic plates. The reconstruction then reveals the even earlier supercontinent Rodinia, which formed from the ancient supercontinent Nuna around 1.35 billion years ago.
