Fashion insiders and beauty magazines have long cited the "20-year-rule"—the idea that clothing trends often resurface every two decades. According to Northwestern University scientists, that observation isn't just anecdotal. ...
Phys.org / Most mass spectrometers can process just a few molecules at once: Reengineered prototype does a billion simultaneously
Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a time, an approach that ...
Medical Xpress / Why scientists are exploring brain cooling as a defense against altitude sickness
In the 2021 Netflix documentary "14 Peaks: Nothing Is Impossible," elite mountaineer Nirmal Purja races up the world's highest summits at extraordinary speed. But even he isn't immune to altitude.
Medical Xpress / Smartwatch and blood test data combine to better predict insulin resistance and diabetes
Around 20–40% of the general population are estimated to have insulin resistance—a condition where insulin begins to be less effective in the body, and glucose regulation becomes more difficult. Eventually, this can lead ...
Medical Xpress / Why some moments endure: Episodic memory encoding fluctuates with brain's theta rhythms
For almost a century, psychologists and neuroscientists have been trying to understand how humans memorize different types of information, ranging from knowledge or facts to the recollection of important events. Past studies ...
