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.....»»
Study uses plankton genomes as global biosensors of ocean ecosystem stress
By analyzing gains and losses in the genes of phytoplankton samples collected in all major ocean regions, researchers at the University of California, Irvine have created the most nuanced and high-resolution map yet to show where these photosynthetic.....»»
Objective analysis of stress in the classroom
Is it the difficulty of a task that determines whether or not students are stressed when working on it? Dr. Nina Minkley, a biologist working in biology didactics at Ruhr-Universität Bochum (RUB), set out to find out the answers in an interdisciplin.....»»
Airborne laser scanning of gaps in Amazon rainforest helps explain tree mortality
A group of researchers led by Brazilians has used an innovative model to map gaps in the Amazon rainforest and identify factors that contribute to tree mortality. Water stress, soil fertility, and anthropic forest degradation have the most influence.....»»
Another study finds a good reason to switch from smoking to vaping
When it comes to harm reduction, switching from smoking cigarettes to vaping an electronic cigarette may be ideal for helping protect your health, at least according to a new study from Imperial Brands. That’s not to say that vaping is a health.....»»
Adjusting interactions help some of California"s wild bee populations survive
Across California's Central Valley, under stress from large-scale agriculture and climate change, native bee species that are flexible in their pollination behavior when around other wild bee populations appear best suited for survival in shrinking h.....»»
Global warming causes uneven changes in heat stress indicators
As the planet warms under the effects of human-caused climate change, prolonged periods of high temperatures are projected to become a significant public health challenge. The elderly are often more susceptible than others to the effects of temperatu.....»»
When parole, probation officers choose empathy, returns to jail decline
Heavy caseloads, job stress and biases can strain relations between parole and probation officers and their clients, upping offenders' likelihood of landing back behind bars......»»
Study shows survival mechanism for cells under stress
New research reveals how cancer cells endure stress and survive. Publishing in Molecular Cell, an international research team identified mechanisms that human and mouse cells use to survive heat shock and resume their original function—and even pas.....»»
"Animal-stress" signal improves plant drought resilience
A team of Australian and German researchers has discovered a novel pathway that plants can use to save water and improve their drought tolerance......»»
The persistent danger after landscape fires
Reactive oxygen species (ROS) cause oxidative stress at the cellular level. Research shows that this way, amongst others, they inhibit the germination capacity of plants, produce cytotoxins or exert toxic effects on aquatic invertebrates. Environment.....»»
Deadly heat waves will be common in South Asia, even at 1.5 degrees of warming
Residents of South Asia already periodically experience heat waves at the current level of warming. But a new study projecting the amount of heat stress residents of the region will experience in the future finds with 2 degrees Celsius of warming, th.....»»
At least 2.6 million Australians face poverty when COVID payments end and rental stress soars
Many Australians whose jobs were decimated by the COVID business shutdowns will soon be waking up to new income shocks and the prospect of rental stress. This is because people whose employers can't afford to keep them on will suddenly lose more than.....»»
Researchers show where and how plants detect the nutrient potassium
Potassium is an essential nutrient for all living things. Plants need it in large quantities, especially for growth and in order to withstand stress better. For this reason, they absorb large quantities of potassium from the soil. In agriculture, thi.....»»
Cancer cells may evade chemotherapy by going dormant
Cancer cells can dodge chemotherapy by entering a state that bears similarity to certain kinds of senescence, a type of 'active hibernation' that enables them to weather the stress induced by aggressive treatments aimed at destroying them, according.....»»
Scientists discover cellular stress enzyme that might play key role in neurodegenerative diseases such as ALS
An enzyme called MARK2 has been identified as a key stress-response switch in cells in a new study......»»
Stress reduction as a path to eating less fast food
Overweight low-income mothers of young kids ate fewer fast-food meals and high-fat snacks after participating in a study - not because researchers told them what not to eat, but because the lifestyle intervention being evaluated helped lower the moms.....»»
Discovery identifies non-DNA mechanism involved in transmitting paternal experience to offspring
It has long been understood that a parent's DNA is the principal determinant of health and disease in offspring. Yet inheritance via DNA is only part of the story; a father's lifestyle such as diet, being overweight and stress levels have been linked.....»»
The valuable contribution of stress to the thermal stability of nanograined polycrystalline alloys
Nanograined metals and alloys, whose grain size is less than 100 nm, exhibit extremely high strength and high ductility, possessing excellent mechanical properties. Nanograined materials, however, have a large number of grain boundaries and hence hig.....»»
The Perplexing Psychology of Returning to ‘Normal’
For a year now, we’ve been living in constant fear of Covid-19. But when you get that vaccine in your arm, it’s not like your stress will magically melt away......»»
