A protocol for annotation of total body photography for machine learning to analyze skin phenotype and lesion classification 3:59

A protocol for annotation of total body photography for machine learning to analyze skin phenotype and lesion classification

A skin-scanning system can be good at judging one spot, yet still miss the person around it. This paper asks whether the whole body, medical history, and change over time can make that judgment safer.

Parents’ self-reporting of Child Physical Maltreatment (CPM) in a low-middle-income country 3:20

Parents’ self-reporting of Child Physical Maltreatment (CPM) in a low-middle-income country

During the pandemic, official reports of child harm went down, but that did not necessarily mean children were safer. A survey of Egyptian parents found a much darker picture inside the home.

Meaning making and fostering radical hope: applying positive psychology to eco-anxiety research in youth 4:01

Meaning making and fostering radical hope: applying positive psychology to eco-anxiety research in youth

A young person’s fear about climate change may not be a problem to erase. It may be a signal that something important is being threatened, and that the person cares enough to act.

The impact of bleeding event frequency on health-related quality of life and work productivity outcomes in a European cohort of adults with haemophilia A: insights from the CHESS II study 3:18

The impact of bleeding event frequency on health-related quality of life and work productivity outcomes in a European cohort of adults with haemophilia A: insights from the CHESS II study

A bleeding event is not only a medical problem. In adults with haemophilia A, more bleeding was linked with poorer daily life and a much larger loss of work productivity.

Onset of periodontitis — a registry-based cohort study 2:47

Onset of periodontitis — a registry-based cohort study

Gum disease can look like an adult problem, but this study found clues as early as nineteen. The surprise is that the warning may be visible before serious damage begins.

A sensitive soil biological indicator to changes in land-use in regions with Mediterranean climate 2:52

A sensitive soil biological indicator to changes in land-use in regions with Mediterranean climate

Healthy-looking soil can hide important damage when the weather is kind. This study finds that the clearest warning may appear when soil faces its hardest season: a dry spell.

Scalable decision-making for games of imperfect information 4:10

Scalable decision-making for games of imperfect information

For years, computers could master games where everything was visible, but hidden information stopped them cold. Then one system beat Stratego’s most decorated human player by a margin never seen at the highest level.

Hair sheep in the Americas: economic traits and sustainable production 3:52

Hair sheep in the Americas: economic traits and sustainable production

What if the best sheep for a warming world are not the ones with the thickest wool? Hair sheep can keep producing in heat, tolerate rough feed, and resist the parasites that destroy ordinary farm output.

A comprehensive UHPLC-MS/MS and extraction method reveals flavonoid profile and concentration are diverse in spinach (Spinacia oleracea L.) 4:50

A comprehensive UHPLC-MS/MS and extraction method reveals flavonoid profile and concentration are diverse in spinach (Spinacia oleracea L.)

Spinach is not chemically simple: its leaves contain a surprisingly varied collection of protective compounds, and the amount can differ greatly from one variety to another. That matters for nutrition research because you cannot study what you cannot reliably measure.

Precipitation explains GRACE water storage variability over large endorheic basins in the 21st century 4:18

Precipitation explains GRACE water storage variability over large endorheic basins in the 21st century

When a satellite detects water rising and falling across an entire inland basin, what is really driving those changes? This study finds that rainfall, more than water leaving the ground, explains much of the year-to-year movement.

Reporting delays of chikungunya cases during the 2017 outbreak in Lazio region, Italy 3:15

Reporting delays of chikungunya cases during the 2017 outbreak in Lazio region, Italy

During the 2017 chikungunya outbreak in Italy, people often became ill long before health officials knew an outbreak was happening. Even after detection, the typical delay was still long enough for transmission to continue.

Excitatory somatostatin interneurons in the dentate gyrus drive a widespread seizure network in cortical dysplasia 3:50

Excitatory somatostatin interneurons in the dentate gyrus drive a widespread seizure network in cortical dysplasia

Some brain cells are supposed to act like brakes during seizures. But in a form of epilepsy linked to abnormal brain development, one group of those supposed brakes may instead help a seizure spread.
