    Guiding questions to avoid data leakage in biological machine learning applications (2024) Nature Methods 21 , S. 1444-1453. DOI: 10.1038/s41592-024-02362-y

    Machine learning methods for extracting patterns from high-dimensional data are very important in the biological sciences. However, in certain cases, real-world applications cannot confirm the reported prediction performance. One of the main reasons for this is data leakage, which can be seen as the illicit sharing of information between the training data and the test data, resulting in performance estimates that are far better than the performance observed in the intended application scenario. Data leakage can be difficult to detect in biological datasets due to their complex dependencies. With this in mind, we present seven questions that should be asked to prevent data leakage when constructing machine learning models in biological domains. We illustrate the usefulness of our questions by applying them to nontrivial examples. Our goal is to raise awareness of potential data leakage problems and to promote robust and reproducible machine learning-based research in biology.

    A Look Inside – Histopathological Examinations of Different Tail Tip Lesions in Dairy Cows (2024) animals 14 (14). DOI: 10.3390/ani14142094

    Feedlot cattle are frequently affected by inflammation and necrosis of the tail tips, resulting in impeded animal welfare and economic losses. In a recent study it was demonstrated that dairy cows are also affected by different lesions of the tail tip, among others alopecia, annular constrictions, crusting, scaling and swelling. Despite the frequent occurrence of these lesions, the underlying etiology and pathomechanisms are unclear to date. To gain insight into this malady, we histopathologically examined 16 tail tips of slaughtered dairy cows, representing the entire bandwith of different lesions. While macroscopically alopecic areas were characterized by the formation of granulation tissue in the dermis with unconspicuous epidermis, we found not only dermal granulation tissue but also purulent-necrotizing inflammation with breakdown of the basement membrane in encrusted lesions. Interestingly, in some cases we found herds of coagulation necrosis of epidermal and dermal layers in the crusts. Tails with macroscopical scaling were affected by ortho- and/or parakeratotic hyperkeratosis and in tails with macroscopical swelling, we observed a low-protein edema of the central longitudinal connective tissue of the tail. We conclude that the observed lesions might be caused by ischemia of the skin in distal parts of the tail.

    The local range of natural cosmetics: Consumer perceptions and assessments in Germany (2024) Business Strategy and the Environment . DOI: 10.1002/bse.3862

    Natural cosmetics offer the opportunity to reduce the environmental burden caused by the consumption of cosmetic products. This qualitative study analyzes the local range of natural cosmetics and related consumer perceptions and assessments in two case cities in Germany by applying a mixed-method approach of store checks and the photovoice method. Results of the study show that there is only a limited match of the actual range and consumer perception for some types of retail businesses and a mismatch for product categories. Additionally, participants showed little awareness of the most common natural cosmetic certifications. Consumer assessments about the range of natural cosmetics were influenced by factors such as the arrangement of products in the shops and consumers' experience and knowledge about natural cosmetic brands. Retailers can use the study results in arranging natural cosmetics accordingly; companies can use it to emphasize branding, and policy-makers can increase consumer knowledge about natural cosmetics.
