Air samples collected on clean days were often more toxic to lung cells than those collected on polluted days thanks to MCFPs, whose sources include vehicular emissions. | Photo Credit: Previn Samuel/Unsplash Governments and scientists often judge air quality by the amount of fine particulate matter (PM2.5) in it. These particles can enter deep into…

John Clarke (University of California, Berkeley), Michel H. Devoret (Yale University, Connecticut and University of California, Santa Barbara), and John M. Martinis (University of California, Santa Barbara) have shared the 2025 Nobel Prize in physics. The prize recognises their contributions to experimentally demonstrating the manifestation of quantum effects in macroscopic systems, confirming our faith that…

A wafer of quantum computers. Representative image. | Photo Credit: Steve Jurvetson Randomness is essential today. From encrypting sensitive information to simulating biological systems, unpredictable numbers are indispensable. Yet most everyday random numbers aren’t truly random. Conventional computers use algorithms called pseudorandom number generators to produce sequences that look random but are ultimately predictable if…

Paleoseismology helps scientists understand how frequently large earthquakes have occurred in the past — especially in regions with incomplete or no historical seismic records. By studying traces of ancient earthquakes preserved in the ground, researchers can determine when they occurred, how strong they were, how often they might recur, and how geological faults evolve over…

You are sitting in your class, and your teacher is writing on the board using chalk. Sqqqqquuuueeeaaakkkkk — there’s a sudden disturbance as the chalk scratches the board loudly. You automatically put your hands over your ears to escape the loud screeching noise. This is a common scenario you would have faced in your school….
Science quiz: Scientific terms that are palindromes Visual: In 1977, a telescope in the US picked up the signal whose intensity is depicted here. It’s been called the ____ signal because of its highly unusual strength and long duration. Such a signal has never been detected since and scientists are still looking for an explanation. …

Onions cut by steel blades of varying sharpness and speed matter, according to a new study. | Photo Credit: Becca Tapert/Unsplash Onions eject eye-irritating chemicals that have a tear-inducing property. When you pierce the skin of an onion, you are left with stinging eyes caused by chemicals released from the onion that affect your nerves…
