Association between depression and endometriosis using data from NHANES 2005–2006
Abstract Studies on the association between depression and self-reported endometriosis are limited, and further studies are required to investigate this association. Data were collected from the National Health and Nutrition Examination Survey database (2005–2006). Based on the inclusion and exclusion criteria, 100 participants with self-reported endometriosis and 1295 participants without self-reported endometriosis were included, representing…

Dust drove dinosaurs’ extinction after asteroid impact, scientists say
In the end it was the dust that did it for the dinosaurs. At least that is the finding of computer simulations of the aftermath of the asteroid impact that reshaped life on Earth 66m years ago. The cataclysmic impact in what is now Chicxulub on Mexico’s Yucatán peninsula wiped out 75% of species on…

These Creatures are Probably the Closest Thing Nature Has to Real Werewolves
Credit: Oxford Scientific Films/Getty Images Under the right conditions, the spadefoot tadpole will transform into a voracious predator of its own species. Full Transcript Brian Gutierrez: Werewolves aren’t real. Everyone knows that. But stay with me for a moment while I tell you about the spadefoot frogs—specifically, their tadpoles, which just might be the closest…

Scientists used to avoid phrases like ‘climate crisis.’ Not anymore.
Bill Ripple had never been an activist. The Oregon State University ecologist had spent his career wandering through the hills and canyons of Yellowstone National Park, tracking the health of wolves and other large carnivores. Nor was he particularly outspoken: As a college student, he was so concerned about taking a debate class that he…

Synthesis and physicochemical characterization of carbon quantum dots produced from folic acid
Abstract The rising interest in carbon dots (c-dots) is driven by their remarkable potential in the field of biomedical applications. This is due to their distinctive and adjustable photoluminescence characteristics, outstanding physicochemical properties, excellent photostability, and biocompatibility. Herein, carbon dots were successfully produced via the heat synthesis method and characterization for physical and chemical properties…

Experimental investigation and modelling of the mechanical properties of palm oil fuel ash concrete using Scheffe’s method
Abstract This study explores the enhancement of mechanical properties in concrete blended with palm oil fuel ash (POFA) through Scheffe’s optimization. The utilization of POFA as supplementary cementitious material in concrete has gained attention for its potential environmental benefits. Utilizing a (5,2) simplex-lattice design, a systematic approach is employed for optimizing mixture proportions based on…

Conceptualizing the construct of ocean identity
The construct of ocean identity provides a valuable lens that can unpack the multiple dimensions of human connections with ocean spaces, and crucially places importance on the integration of cognitive, affective, and behavioral components. The construct of ocean identity is applicable in academic and professional contexts, and is largely unexplored from both qualitative and quantitative…

How to switch research fields successfully
Changing disciplines is like jumping in at the deep end, but there are strategies for achieving a positive outcome.Credit: Andrea Pistolesi/Getty Interdisciplinary training and research are increasingly valued for their contributions to solving complex problems that a single discipline cannot overcome. One 2021 study that tracked more than 44,000 grants awarded in the United Kingdom…
