Why vaping can mean more — not less — stress
Within minutes of your first puff on a nicotine vape, you may have felt less stressed, more focused, and oddly like you had just aced a test. You felt good. Sadly, nicotine can make a great first impression — but then the mind games take over f.....»»
E-Cigarettes Could Be the New Nicotine Patch
England will allow doctors to prescribe vaping devices to people who want to quit smoking—if manufacturers can develop a product that works......»»
How corals react to climate change
Ph.D. student Fabian Gösser from the Department of Animal Ecology, Evolution and Biodiversity has been studying how corals react to changing environmental conditions and how their stress response could contribute to the survival of the reefs. The RU.....»»
Researchers recreate deep-Earth conditions to see how iron copes with extreme stress
Far below you lies a sphere of solid iron and nickel about as wide as the broadest part of Texas: the Earth's inner core. The metal at the inner core is under pressure about 360 million times higher than we experience in our everyday lives and temper.....»»
Female bushbabies are more stressed, may be more vulnerable to changing environment
A new study has explored the yearly routine of a small primate called the thick-tailed greater galago (Otolemur crassicaudatus), discovering that females may be under a lot more stress than males......»»
Does environmental stress drive migration?
With the United Nations climate conference in Glasgow, the world is focused on the consequences of a climate crisis and how we can still change course. Yet while climate-driven migration has been deemed a major threat in public discourse and academic.....»»
Using neutrons to analyze modified high-entropy metal alloys
Researchers at Oak Ridge National Laboratory have developed a method of adding nanostructures to high-entropy metal alloys, or HEAs, that enhance both strength and ductility, which is the ability to deform or stretch under tensile stress without fail.....»»
PTSD symptoms vary over course of menstrual cycle, research finds
In women who have experienced trauma, post-traumatic stress disorder symptoms may vary over the course of the menstrual cycle, with more symptoms during the first few days of the cycle when the hormone estradiol is low, and fewer symptoms close to ov.....»»
Best tools to stress test your CPU
Stress-testing your CPU can be an excellent way to gauge how powerful it really is. Here are a few tests we think you should check out to maximize performance......»»
Nurses as parents exemplify link between poor sleep and daily stress
A new article details how nurses who also are parents might be more susceptible than other groups to daily stress aggravated by poor sleep......»»
Brain connectivity is lower in adults with PTSD or a history of sexual abuse
A study has found that adults with maltreatment-related posttraumatic stress disorder or a history of sexual abuse have lower brain connectivity in the attention systems known as the ventral and dorsal attention network. These networks enable us to s.....»»
Scientists discover how bacteria use liquid protein droplets to overcome stress
Scientists have revealed how bacteria make tiny liquid droplets from proteins to help them survive harsh environments and thus reduce their chances of being killed by antibiotics......»»
Brain circuitry for both positive and negative "valence" affected by trauma
Research has revealed that the brain employs distinct circuitries that mediate positive, or rewarding, behaviors and negative, or aversive, ones. Post-traumatic stress disorder (PTSD) has long been thought to arise from overactivity in the negative v.....»»
Scientists identify protein that stops cell cycle in response to stress
UT Southwestern researchers have identified a new mechanism by which stress causes cells to stop dividing......»»
Stress Levels Revealed in Micro-Beads of Sweat
Sweat analysis isn't new: the dynamic chemical composition of perspiration has inspired researchers from elite athletic performance specialists to chronic disease experts to try to decipher its signals.But translating raw perspiration into "sweat equ.....»»
Scientists reveal genetic secrets of stress-tolerant mangrove trees
Mangrove trees straddle the boundary between land and ocean, in harsh environments characterized by rapidly changing levels of salinity and low oxygen. For most plants, these conditions would mark a death sentence, but mangroves have evolved a remark.....»»
Cardboard shortages put additional stress on the supply chain heading into the holidays
Don’t look now, but yet another staple of modern society is in short supply as we head into the holidays. NBC News reports that much like computer chips, packaging materials made out of paper, plastic and cardboard are in short supply, and prices h.....»»
Novel peroxide-based material emits fluorescence in response to stress
Polymers make up everything from the clothes we wear to the plasticware we use for eating. In recent years, polymers that can release small molecules (like drugs) have been of major interest to pharmaceutical researchers. Previous studies have demons.....»»

Big differences found in male and female jojoba plant sex genes
The hot and dry desert environment has led to big genetic differences between male and female jojoba plants, a discovery which could boost jojoba production and shed light on how plants adapt to environmental stress......»»
Protein linked to oxidative stress and related diseases
Scientists at Monash University's Biomedicine Discovery Institute (BDI) have discovered a new role for a known protein in oxidative stress, which is linked to diseases such as Alzheimer's and Parkinson's, diabetes, cardiovascular diseases, viral inf.....»»
