Tiny robots, smaller than the width of a human hair, are no longer just a dream. They are real and have the power to change the world. But why aren't we seeing them everywhere yet? The journey of these micro and nanorobots started with a famous lecture and a sci-fi movie. Now, they are used in medic
In Taiwan, esophageal cancer is a serious health issue. It's tough to treat and often has poor outcomes. Scientists are now looking into how certain chemicals in our environment might play a role in causing this disease. One group of chemicals, called organophosphate flame retardants (OPFRs), has ca
Delhi, a city known for its heavy pollution, has seen some good news lately. Over the past decade, the amount of tiny, harmful particles in the air, called PM2. 5 and PM10, has been going down. This drop is thanks to new eco-friendly tech and stricter rules on industries, even though there are more

Scientists are always looking for ways to make drug delivery more effective. One big challenge is getting drugs to release quickly and efficiently once they reach their target. A recent study tackled this problem by designing smart molecular structures that speed up drug release. The key idea is to
