How Stress Messes With Your Gut
Inflammatory bowel disease flare-ups can be traced to mental stress.....»»
How protein condensation slows down gene activity and ensures the survival of stressed cells
All life on earth evolved multiple layers and networks of ensuring survival upon catastrophic events. Even cells have their emergency plan: the heat shock response. Triggered by multiple stress stimuli such as heat, toxins, or radiation, this cellula.....»»
Signs of burnout can be detected in sweat
EPFL engineers, working in association with startup Xsensio, have developed a wearable system that can continually measure the concentration of cortisol—the stress hormone—in human sweat. Their device can eventually help doctors better understand.....»»
Novel polymer toughens up and changes color upon mechanical stress
A fascinating and crucial ability of biological tissue, such as muscle, is self-healing and self-strengthening in response to damage caused by external forces. Most human-made polymers, on the other hand, break irreversibly under enough mechanical st.....»»
Less job stress for workers at financially transparent firms
Employees feel significantly less job distress if they work at companies that are open and transparent about the firm's finances, including budgets and profits, a new study found......»»
Surprising new mechanism of heat shock response identified in yeast cells
How cells respond in the face of stress is a critical component of maintaining homeostasis and preventing disease, but its mechanisms are poorly understood. New research out of the University of Chicago has fit together another piece of the puzzle by.....»»
Ford ads stress unity following Capitol riot
The spots, called "Builders," debut Saturday during college basketball on Fox and are the latest in Ford's "Built for America" series of commercials that began in 2020......»»
Simulating evolution to understand a hidden switch
Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a disused switch mechanism that turns on under severe stress, changing some of their characteristics. Maintaining this "hidden" switch is on.....»»
Levels of stress hormone in saliva of newborn deer fawns may predict mortality
The first-ever study of the levels of the stress hormone cortisol in the saliva of newborn white-tailed deer fawns yielded thought-provoking results that have Penn State researchers suggesting predation is not the only thing in the wild killing fawns.....»»
Same difference: Predicting divergent paths of genetically identical cells
A set of biomarkers not traditionally associated with cell fate can accurately predict how genetically identical cells behave differently under stress, according to a UT Southwestern study. The findings, published by Cell Reports as a Dec. 1 cover st.....»»
Themis Smart Mirror analyzes skin and stress levels to promote wellness
CareOS wants to disrut the health and wellness market with the Themis Smart Mirror, a wellness companion for your bathroom or spa......»»
Performance fiber with color-changing coating makes mechanical stress visible
High-performance fibers that have been exposed to high temperatures usually lose their mechanical properties undetected and, in the worst case, can tear precisely when lives depend on them. For example, safety ropes used by fire brigades or suspensio.....»»
Novel method to quantify decomposition of rhizodeposits
Rhizodeposition of labile organic carbon is one of the main pathways linking above- and below-ground biota to affect soil carbon cycling. Rhizodeposition is also a strategic physiological process for plants to cope with environmental stress, such as.....»»
Gift Guide: TechCrunch’s Favorite Things of 2020
It goes without saying, but 2020 was a bad year for a lot of people. For many, it was a year of stress, of sadness, and anxiety. It was a year of missing friends and family; of just getting to the next day, even as each day seemed to blur into the la.....»»
Hormone metabolites found in poop give researchers new insight into whale stress
Poop samples are an effective, non-invasive tool for monitoring gray whale reproduction, stress and other physiological responses, a new study from Oregon State University shows......»»
Training methods based on punishment compromise dog welfare, study finds
Dogs trained using aversive stimuli, which involve punishments for incorrect behavior, show evidence of higher stress levels compared to dogs trained with reward-based methods, according to a study publishing December 16 in the open-access journal PL.....»»
COVID-19 turned parents into proxy educators; new research examines the stress it caused
When the emerging COVID-19 pandemic caused most U.S. schools to close and transition to distance learning last spring, many parents were forced into new roles as proxy educators for their children. A study published today in Educational Researcher, a.....»»
