The volcanic history of the late Pleistocene Shamao complex, Tatun Volcano Group, northern Taiwan 4:09

The volcanic history of the late Pleistocene Shamao complex, Tatun Volcano Group, northern Taiwan

A volcano beside Taiwan’s capital may look like one old mound. This study finds it is a layered record of separate eruptions, separated by roughly 170,000 years.

Scalar superradiance in the charged black-bounce spacetimes 3:52

Scalar superradiance in the charged black-bounce spacetimes

A black hole can act like a cosmic energy booster, making incoming waves leave stronger than they arrived. This study finds that a quantum-scale change to the black hole’s shape turns that booster down.

Digital capabilities relate to sustainable performance in Saudi SMEs through technological capabilities and eco innovation 4:08

Digital capabilities relate to sustainable performance in Saudi SMEs through technological capabilities and eco innovation

For a small business trying to become more efficient and sustainable, buying the latest digital tool may not be enough. In this study, some tools strengthened a company’s technological ability, but others showed no independent link at all.

Assessing financial toxicity with COST-FACIT: experience from a tertiary care cancer center 4:19

Assessing financial toxicity with COST-FACIT: experience from a tertiary care cancer center

Cancer can bring a second crisis besides the disease itself: bills, lost income, travel, childcare, and medication costs. This study asks who is most exposed to that pressure, and what it is connected to.

Comparative evaluation of Risser sign and Kreitner–Kellinghaus modified system for age estimation using iliac crest ossification in Egyptians 3:51

Comparative evaluation of Risser sign and Kreitner–Kellinghaus modified system for age estimation using iliac crest ossification in Egyptians

A pelvic X-ray may make adulthood more likely, but it cannot prove someone is eighteen. This study found that the choice of grading system can sharply change how trustworthy that judgment becomes.

Habituation and housing interact to shape the magnitude and consistency of post-operative recovery after kidney imaging window implantation in mice 3:31

Habituation and housing interact to shape the magnitude and consistency of post-operative recovery after kidney imaging window implantation in mice

A routine step before surgery, gently handling mice so they become used to people, did not simply make recovery better or worse. Its effect depended on who the mice were and where they lived afterward.

Performance analysis of a metal hydride reactor for hydrogen storage using ethylene glycol-based coolants as heat transfer fluids 3:25

Performance analysis of a metal hydride reactor for hydrogen storage using ethylene glycol-based coolants as heat transfer fluids

Hydrogen can store energy for heavy transport and industry, but storing it is not as simple as filling a tank. A coolant choice may shorten the storage cycle, while demanding far more pumping power.

Climate change exacerbates residential radon exposure and lung cancer risk 3:39

Climate change exacerbates residential radon exposure and lung cancer risk

Staying indoors and turning up the air conditioning can protect people from heat. But this study suggests those same choices may quietly increase exposure to radon, a gas linked to lung cancer.

Long-Term Survival of a Maxillary Subperiosteal Implant After Blast Injury: A 17-Year Follow-Up Case Report 2:35

Long-Term Survival of a Maxillary Subperiosteal Implant After Blast Injury: A 17-Year Follow-Up Case Report

A dental implant stayed stable for seventeen years, and then endured a high-energy blast. The visible replacement was damaged, but the structure supporting it remained usable.

Mineralogy and leaching characteristics of rare earths from the micro-dispersed mineral matter in the organic matrix of Fire Clay coal 3:45

Mineralogy and leaching characteristics of rare earths from the micro-dispersed mineral matter in the organic matrix of Fire Clay coal

Coal is usually burned for energy, but it can also hide rare earths, materials needed in many modern technologies. The surprise is that the easiest ones to release are not distributed evenly: acidity changes which rare earths come out.

A physical model approach to order lot sizing 3:46

A physical model approach to order lot sizing

Every company has to choose between ordering often and paying for each order, or ordering in bulk and paying to store the extra. This paper turns that balancing act into the behavior of a simple mechanical system.

Revisiting the correlates of carbon emissions in Africa using a CS-ARDL model: does obesity matter? 4:46

Revisiting the correlates of carbon emissions in Africa using a CS-ARDL model: does obesity matter?

Could rising obesity make climate change worse? The idea sounds plausible: heavier food demand might mean more livestock, more land use, and more emissions. But across Africa, this study found no detectable link.
