Imagine waking up, putting a few drops into your eyes, and reading a text message or a restaurant menu without reaching for your reading glasses. It sounds like something from a science-fiction movie, but it’s becoming a reality for many people with presbyopia, the age-related difficulty in seeing nearby objects …
Have you ever listened to a voice note or watched a video of yourself and wondered, “Do I really sound like that?” For many people, hearing their own recorded voice is surprisingly uncomfortable. It often seems higher, thinner, or somehow less “you.” The surprising answer is yes, that’s very close …
When you switch on your phone, tiny flashes of light carry information that lets you send messages across the world. Surprisingly, scientists now think something similar may be happening inside your own cells, not with visible light, but with incredibly faint flashes that no human eye can see. Every cell …
At first, it sounds impossible. How can one baby have DNA from three different people? Is it science fiction? A cloning experiment? Or something straight out of a movie? The truth is even more fascinating. It’s a medical technique designed not to create “three-parent babies,” but to prevent children from …
When astronomers look deeper into space, they are also looking further back in time. This is because light does not travel instantaneously, it moves at a finite speed. Light from nearby stars takes only a few years to reach Earth, but light from the most distant galaxies can take billions …
Our skin is remarkably good at repairing itself. A small cut, scrape, or burn can heal within days, often with very little intervention. Yet even after the wound has closed, it may leave behind a scar, a permanent reminder of an injury. Why doesn’t the body simply replace damaged skin …
Hydrogen is often called the fuel of the future, but not all hydrogen is produced in the same way. The type attracting global attention today is green hydrogen, hydrogen made using renewable energy such as solar or wind power. So, what makes it “green”? Green hydrogen is produced through a …
At first glance, it seems impossible that a change in the Pacific Ocean could affect rainfall in India. However, the Earth’s oceans and atmosphere are constantly connected. Every year, steady winds blow across the Pacific Ocean, pushing warm surface water towards Asia and Australia. This allows colder, nutrient-rich water to …
Some of the biggest scientific discoveries begin with a simple question. Others begin completely by accident. The story of CRISPR, one of the most powerful gene-editing tools ever developed, belongs to the second category. It all started in 1987, when Japanese scientist Yoshizumi Ishino and his team were studying a …
A vaccine doesn’t go from a laboratory to a hospital overnight. Before it reaches the public, it goes through years of research and several rounds of testing to answer two important questions: Is it safe? And does it work? The journey begins with preclinical research. Scientists first study the vaccine …
