Science X Dialog

The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at high-redshift. The redshift ...

Can we use nothing more than sunlight and inexpensive materials to produce clean hydrogen fuel while also removing toxic pollutants from water? That question shaped our recent work with γ-In2S3, a semiconductor that has ...

I still vividly remember the first time we observed neurons responding not to audible sound, but to concentrated, precisely calibrated ultrasonic pulses. On the screen in front of us, calcium signals from brain cells began ...

Many have spent much of their career studying disasters—how people perceive risk, how institutions communicate, and why preparedness so often falls short of good intentions. But this study forced me to confront something ...

Hospital beds are a brutally concrete resource. When they're full, surgeries get delayed, hallways become overflow wards, and staff burn out. So a question I keep coming back to is simple: can the way we label food, those ...

In recent years, numerous landslides on hillsides in urban and rural areas have underscored that understanding and predicting these phenomena is more than an academic curiosity—it is a human necessity. When unstable slopes ...

Remember seeing your triglyceride levels in your lab report? Ah! Fats you may dismiss, thinking of the next gym work you need to head to. Fatty acids are broken down via a process called β-oxidation. But did you ever wonder ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose ...

Fluorine has changed the world of medicine. You might not see it, but newly approved drugs contain at least one fluorine atom. This tiny but powerful element is the "hidden engine" that makes our medications more stable and ...

I have spent much of my professional life thinking about buildings—how they are designed, how they are constructed and how they shape daily life. But some structures matter far more than we usually admit. In places affected ...

Water is everywhere, from the snowpack in the mountains to the tap in our kitchens. But while we often think about rainfall and snow as the main drivers of our water supply, it turns out that something we rarely see has just ...

Graphene has drawn attention as a scientific curiosity owing to its record conductivities, strength and thermal properties. But now, it's starting to make its way into a number of real-world applications, from batteries to ...
