Maternal stress during pregnancy may shorten lifespans of male lizard offspring
Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with.....»»
Model highlights three roots of online toxicity
In 2022, Professor of Cognitive Neuroscience Dean Mobbs began to investigate the relationship between social media use and mental health and well-being. As his research program ramps up to test brain activity and physiological markers of stress durin.....»»
Ecosystems study finds the higher the environmental stress, the lower the resistance to global change
An international study led by the Institute of Natural Resources and Agrobiology of Seville (IRNAS-CSIC), of the Spanish National Research Council (CISC), has shown that as the number of global change factors increases, terrestrial ecosystems become.....»»
Advances in bermudagrass research highlight genetic insights, potential for environmental resilience
A research team has reviewed recent studies to highlight the significant progress in understanding the growth and stress response mechanisms in bermudagrass, a widely distributed and valuable grass species. A recent review reveals the genetic diversi.....»»
How "winner and loser effects" impact social rank in animals—and humans
Research has shown that in many animals, the winners of a fight are more likely to win subsequent contests, while the losers tend to lose their following fights. In experiments where male stickleback fish were randomly introduced to another fish, 65%.....»»
Going slow is better for fast cycling: Study reveals unique replication fork behavior in pluripotent stem cells
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic replication stress. However, a recent report published in E.....»»

Lab experiment shows Joro spider heart rates fluctuate less under stress
A pair of entomologists at the University of Georgia has found that Joro spider heart rates fluctuate less when they are experiencing stress compared to similar spiders. In their study, published in the journal Physiological Entomology, Andrew Davis.....»»
Urban growth leads to more intense droughts for many world cities—Sydney is a case study for areas at risk
The growth of cities worldwide is contributing to more intense drought conditions in many cities, including Sydney, a new Chinese study has found. This is adding to urban heat and water stress. These important findings point to the need to improve ho.....»»
The FDA Just Rejected a Bid for MDMA to Treat PTSD

Japan"s "megaquake" warning explained
Japan's earthquake scientists say the country should prepare for a possible "megaquake" one day that could kill hundreds of thousands of people—although they stress the warning does not mean a colossal tremor is imminent......»»
Shorter TLS certificate lifespans expected to complicate management efforts
76% of security leaders recognize the pressing need to move to shorter certificate lifespans to improve security, according to Venafi. However, many feel unprepared to take action, with 77% saying the shift to 90-day certificates will mean more outag.....»»
Study reveals mechanism used by tegu lizard to raise own temperature
A group of scientists has revealed the mechanism whereby Salvator merianae—the black and white tegu, also called the Argentine giant tegu—is able to keep warm by raising its own body temperature during the reproductive season even while it is in.....»»
Editing for resilience: CRISPR/Cas9 boosts potato stress resistance
Scientists have made a significant breakthrough in agricultural biotechnology by using CRISPR/Cas9 to edit the potato genome, resulting in plants with increased resistance to both biotic and abiotic stresses. This innovation could lead to a new era o.....»»
Male and female lions socialize differently throughout their lives, study reveals
New research from the University of Oxford on wild lions has revealed that males and females experience vastly different changes to their social network throughout their lives, and that this may shape their survival......»»
