Emission rates for volatile organic compounds (VOCs) have been quantified from frying, spice and herb cooking, and cooking a chicken curry, using real-time selected-ion flow-tube mass spectrometry (SIFT-MS) for controlled, laboratory-based experiments in a semi-realistic kitchen. Emissions from 7 different cooking oils were investigated during the frying of wheat flatbread (puri). These emissions were dominated by ethanol, octane, nonane and a variety of aldehydes, including acetaldehyde, heptenal and hexanal, and the average concentration of acetaldehyde (0.

In this Viewpoint, we emphasise the importance of microbiology reference laboratories and highlight the types of digital data and expertise they provide, which benefit national and international public health.

We considered informed dispersal in relation to settlement location, where individuals could optimise selection of settlement location with regard to per capita resource availability and investigated the importance of this type of informed dispersal for simulated demography and genetic diversity under different biological and environmental scenarios. We used an individual-based simulation model scaled with reference to the ecology of small mammals in fire prone savanna ecosystems.

- The study focuses on identifying genetic mutations in malaria parasites that confer drug resistance, essential for improving surveillance and target discovery in malaria treatment.
- Researchers analyzed the genomes of 724 clones resistant to 118 different antimalarial compounds, uncovering 1,448 variants in 128 frequently mutated genes related to multidrug resistance.
- The findings suggest that in vitro selected mutations are more diverse and significant than naturally occurring ones, providing insights into how these mutations can inform predictions of drug resistance in similar pathogens.
Article Synopsis
- Underwater ecosystems are increasingly affected by anthropogenic noise, which leads to significant uncertainty about its impact on aquatic communities.
- A meta-analysis of 835 data points from 46 studies revealed that anthropogenic and synthetic sounds negatively impact aquatic invertebrates' behavior and physiology, while environmental sounds have a slightly positive effect.
- The research highlights the need to include aquatic invertebrates in studies on noise pollution and its effects, as their sensitivity to sound changes can have significant repercussions for individual species and aquatic ecosystems.
