Phys.org / Bell-bottoms today, miniskirts tomorrow: Math reveals fashion's 20-year cycle
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 ...
Phys.org / Measuring irreversibility in gene transcription
Living cells are fundamentally nonequilibrium systems, meaning they constantly spend energy through seemingly one-way, irreversible processes, such as transcribing DNA into RNA, to keep life going. But how that irreversibility ...
Medical Xpress / As demand for GLP-1 pills and shots surges, healthy habits are still key
Whether they're using weekly shots or daily pills, more Americans than ever are turning to anti-obesity drugs to lose weight and boost health.
Medical Xpress / Could a gut microbe influence muscle strength?
The trillions of microbes living in the human gut are increasingly recognized as important partners in human health. Scientists have linked the gut microbiome to several aspects of health, from metabolism and immunity to ...
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 ...
Phys.org / Predicting RNA activity expands therapeutic possibilities
With AI, it's now possible for researchers to predict the three-dimensional structures of proteins directly from their amino-acid sequences. But what biologists really want to predict, says Columbia biophysicist Hashim Al-Hashimi, ...
Phys.org / A 'consortium' of bacteria cooperates to eat phthalate plasticizers that single microbes can't stomach
Plastic trash has reached the world's most remote locations, from the bottom of the Mariana Trench to the summit of Everest. Hundreds of plastic-eating microbes that could help us clean up have been discovered over the past ...
Phys.org / A self-sufficient Mars garden? How cyanobacteria-based fertilizer could grow edible biomass
A research team from the Center for Applied Space Technology and Microgravity (ZARM), the Department of Environmental Process Engineering (UVT) at the University of Bremen and the German Aerospace Center (DLR) has made significant ...
Phys.org / Clearing circular RNA from cells extends lifespan, C. elegans study reveals
Cells in our bodies produce RNA based on genetic information stored in DNA, and RNA serves as a blueprint for making proteins. Researchers at KAIST have discovered a new phenomenon: Removing "circular RNA" that accumulates ...
Medical Xpress / Psychosocial factors may not affect overall cancer risk, large-scale analysis suggests
New research indicates that psychosocial factors—which influence how a person perceives, interprets, and reacts to their surroundings—do not affect an individual's risk of developing cancer. The findings, titled "Psychosocial ...
