Accurately modeling volume-dependent properties of water remains a challenge for density functional theory (DFT), with widely used functionals failing to reproduce key features of the water density isobar, including its shape, density, and temperature of the density maximum. Here, we compare the performance of the RPBE-D3 and vdW-DF-cx functionals using replica exchange molecular dynamics (MD) driven by machine-learned force fields. Our simulations reveal that vdW-DF-cx predicts the water density more accurately than RPBE-D3 and reproduces the isobar closely between 307 and 340 K.

ABCC1 promotes GSH-dependent iron transport and resistance to Fe(II) and Cu(II) chelators.

Biometals

August 2025

Integrative Health and Environmental Analysis Research Laboratory, Institute of Chemistry, ELTE Eötvös Loránd University, Budapest, Hungary.

Therapy resistance is a major challenge in cancer treatment, with multidrug resistance (MDR) being a well-characterized phenomenon wherein cancer cells develop resistance not only to the administered drug but also to structurally diverse compounds. Metal chelators, including quinolines and thiosemicarbazones, have shown broad antitumor activity and potential in overcoming MDR by modulating metal metabolism. However, predicting whether chelators increase or decrease toxicity in MDR cells remains complex, especially as chelator-metal complexes may become substrates for ATP-binding cassette (ABC) transporters, leading to resistance or hypersensitivity.

In an age of information overload, misinformation poses a growing threat to democracy. Inoculation theory suggests that exposing individuals to manipulation techniques can help build resistance to misinformation and improve their ability to discern such content over time. However, little research has directly compared the effectiveness of active learning tools, such as gamified interventions, to passive learning methods, like informational guides, for enhancing the detection of misinformation within important public issues, such as elections and climate change.

Whether and to what degree culture modifies cognition has been an area of research often limited by possibilities to gather relevant data across societies. In this project, we leverage webcam-based eye-tracking to study cultural variations of cognitive processes underlying in-group favoritism. Participants (n = 1850, k = 20) are assigned to an in-group based on a color perception task, complete a group reinforcement stage, and then make decisions to allocate points between themselves and random matched players in a repeated decomposed dictator game, facing either an in- or an out-group member.

Global land cover maps are key inputs into the biodiversity metrics used by the private sector to align their performance with conservation goals and targets. These maps utilize classification systems depicting combinations of 'natural' (vegetation, water bodies) and 'anthropogenic' (agriculture and built-up land) cover types, but often miss intensive pressures on biodiversity, such as mining. Here, we reveal that more than half (56-77%) the global land area disturbed by mining is classified by land cover maps as 'natural', suggesting metrics based on these maps likely overestimate the current state of biodiversity and underestimate opportunities to improve it.
