How is the immune system kept in check? | Explained

The story so far: The Nobel Prize season for 2025 began with the announcement of the Physiology or Medicine Prize on October 6. The three awardees — U.S.-based researchers, Mary E. Brunkow and Fred Ramsdell, and Japan’s Shimon Sakaguchi — were chosen for their “discoveries concerning peripheral immune tolerance.” Their discovery enabled a fundamental understanding … Read more

Even on ‘clear’ days, the air can be chemically toxic

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 … Read more

RRI technique yields certified randomness with one qubit

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 … Read more
