A laboratory may contain expensive instruments, advanced computers, and highly specialised equipment, but some of the most important tools are surprisingly simple. A pipette is one such tool. If you have ever seen a laboratory worker transfer a small amount of liquid from one container to another, there is a good chance they used a pipette. This simple-looking instrument helps scientists measure and transfer liquids with much better control than ordinary pouring. The uses of pipettes cover a wide range of scientific work. Researchers use them in chemistry, microbiology, biotechnology, pharmaceuticals, food testing, environmental testing, and medical laboratories. The type…

For many years, antibiotics have helped doctors treat infections that were once dangerous or even deadly. But bacteria are becoming better at surviving these medicines. When bacteria stop responding to commonly used antibiotics, doctors may have fewer treatment options. These difficult-to-treat bacteria are often called superbugs. This problem has become a serious health concern around the world, including India. Antimicrobial resistance can make infections harder to treat, increase hospital stays, and raise the risk of serious illness. Researchers are now looking beyond traditional antibiotics. Two interesting areas are bacteriophage therapy and AI-designed antibiotics. The ideas sound complicated, but the basic…
For decades, scientists have used animals to study diseases, test medicines, and understand how treatments may affect the human body. Animal research has played an important role in medical science, but it also has limitations. A medicine that works safely in an animal does not always behave in exactly the same way in humans. Researchers are finding new ways to study the human body without relying just on animals. Two popular methods are 3D bioprinting and miniature lab-grown organs (organoids). The basic idea is quite interesting. Instead of testing every new medicine on an animal first, scientists can create tiny…
