Caffeine affects people differently because of how long it stays in the body and how quickly it is broken down by the liver. Factors like genetics, smoking, medications, pregnancy, and caffeine tolerance all change how caffeine impacts alertness and sleep.
Key Facts
Caffeine is the world’s most used psychoactive substance, found in coffee, cola, energy drinks, chocolate, and supplements.
It makes people feel more awake by blocking adenosine, a chemical that makes us sleepy.
The liver breaks down caffeine with an enzyme called CYP1A2, and this process can take between 6 and 20 hours depending on the person.
Genetics play a role, with some groups like Europeans and South Americans processing caffeine faster.
Smoking speeds up caffeine breakdown by up to 65%, while some medicines and pregnancy slow it down.
People who drink caffeine regularly develop tolerance, needing more to feel the same effects.
Experts suggest avoiding caffeine at least six hours before bedtime to prevent sleep problems.

Researchers at Stanford University removed a large part of a mouse’s brain cortex and replaced it with human brain organoid cells. This method aims to create a better model to study human brain diseases by combining human brain tissue with a living animal's brain.
Key Facts
Brain organoids are small 3D tissues made from stem cells that mimic some features of real organs but lack full brain connections.
The cortex is the brain area responsible for complex functions like memory and decision-making.
Researchers deleted most of the mouse’s cortical brain cells by targeting a necessary gene for cell division.
Mice without a cortex survived by receiving extra care, including extended nursing and high-calorie food.
This approach helps study brain diseases by allowing human brain cells to integrate into a living brain environment.
Traditional organoids lack blood flow and immune system interactions found in real brains.
Implanting some human brain cells into normal mouse brains is common, but replacing the cortex is a more advanced step.
Human neurons develop slower than mouse neurons, which presents challenges in brain integration.

Scientists developed a new way to identify which ancient scrolls from Herculaneum were written with lead-based ink. This method uses digital scans and machine learning to find the most promising scrolls for virtual reading without unrolling the fragile originals.
Key Facts
The Herculaneum scrolls are 2,000 years old and were damaged by the eruption of Mount Vesuvius in 79 AD.
The scrolls are too fragile to be physically opened because they might crumble.
Researchers created modern model scrolls and burned them to test their scanning method.
Lead-based ink in some scrolls helps X-ray imaging detect the writing because lead shows up clearly in scans.
Most scrolls use carbon-based ink, which is harder to detect using X-rays.
Scientists trained an artificial intelligence program to spot small differences in texture to read texts in carbon ink scrolls.
A retired inventor and a team worked to identify which scrolls have lead-based ink to prioritize them for further virtual unrolling.
This project combines advanced scanning, machine learning, and software tools to digitally unroll and read ancient texts without damage.
