How can cocoa farmers adapt to climate change?
University of GöttingenPeer-Reviewed Publication
Climate change threatens agricultural production across sub-Saharan Africa, where most farmers rely on rainfall. A study by researchers at the University of Göttingen and the European Commission’s Joint Research Centre shows that Ghanaian cocoa farmers who cultivate cocoa under shade trees – a practice known as agroforestry – are better able to withstand periods of reduced rainfall. However, the study also finds that these benefits are confined to Ghana’s wetter regions, which have a climate that better suits growing cocoa. In drier regions, where water is already scarce, the researchers find no significant advantages of agroforestry in maintaining yields during times of less rainfall. The results were published in the journal Agricultural Systems.

Solar-powered breakthrough: Simultaneous freshwater and boron harvesting from seawater
Science China PressPeer-Reviewed Publication
Researchers from China have developed a solar-driven multi-field synergistic strategy to simultaneously harvest freshwater and boron from seawater. The innovative (MXene-MgO)@sodium alginate (SA) composite gel (MMS) achieves high evaporation rates and boron adsorption capacities, offering a sustainable solution to global water and food scarcity.

Ancient DNA reveals a North African origin and late dispersal of domestic cats
American Association for the Advancement of Science (AAAS)Peer-Reviewed Publication
The domestic cat may be a far more recent arrival to Europe than previously thought, arriving roughly 2000 years ago and not because of the Paleolithic expansion of Near East farmers. The findings offer new insight into one of humanity’s most enigmatic animal companions and identify North Africa as the cradle of the modern housecat. The domestic cat has a long and complex, albeit uncertain, history. Genetic studies show that all modern cats descended from the African wildcat, which is found today in North Africa and the Near East. However, sparse archaeological remains and the difficulty of distinguishing domestic from wild felines based on bones alone have left major gaps in our understanding of the origin and spread of early domestic cats. A human-cat burial from ~7500 BCE in Cyprus suggests an early domestication in the Levant region, while later Egyptian art and animal burials point to a possible later origin in Pharaonic Egypt. Recent Genetic studies of ancient DNA have indicated that cats may have dispersed from what is now Türkiye into Europe alongside Neolithic farmers, supporting the idea that cat domestication began in the Levant during the rise of agriculture ~6,000 years ago. However, it remains unclear whether these animals were truly domesticated cats or a distinct lineage of wildcats.
To help resolve some of these mysteries, Marco de Martino and colleagues conducted paleogenomic analyses on 87 ancient and modern cat genomes. De Martino et al. generated 70 low-coverage genomes from archaeological specimens spanning more than 10,000 years (~9000 BCE to 19th Century CE) and 17 higher-coverage genomes from modern and museum wildcats from Europe, North Africa, and Anatolia. Contrary to previous studies, the authors found that domestic cats most likely originated from North African wildcats, rather than from the Levant, and that true domestic cats only appeared in Europe and southwest Asia several thousand years after the Neolithic. Earlier cats in Europe and Türkiye were genetically European wildcats and reflect ancient hybridization rather than early domestication. After being introduced, North African domestic cats spread rapidly throughout Europe, often following Roman military routes, reaching Britain by the 1st Century CE. What’s more, de Martino et al. show that Sardinian wildcats – both ancient and modern – are more closely related to North African wildcats than domestic cats, indicating that humans brought wildcats to islands where they did not naturally occur, and they are not descendants of a feral population of early domestic cats. “The study by de Martino et al. is part of an ongoing project, Project Felix, which also aims to tackle other outstanding questions concerning cat domestication,” writes Jonathan Losos in a related Perspective. “Ever sphinxlike, cats give up their secrets grudgingly.”

Toxic metals in wheat grain: do they come from the soil or the fertilizer?
Helmholtz Centre for Environmental Research - UFZPeer-Reviewed Publication
Plants absorb not only nutrients but also toxic metals such as cadmium through their roots. It was previously unclear whether the toxic metals came from the soil or the fertilisers applied. Under the leadership of the Helmholtz Centre for Environmental Research (UFZ) and Duke University in Durham, North Carolina, a research team has examined wheat grains to clarify the question. Using a special isotope signature, they found that most of the toxic metals come from the mineral fertiliser. A combination of mineral and organic fertilisation would not only reduce the concentration of toxic metals but also increase the concentration of metals important for human nutrition. The researchers reach this conclusion in their study published in Environment International.

Michigan cherry farmers find a surprising food safety ally: falcons
Michigan State UniversityPeer-Reviewed Publication
The cherry harvest wrapped up months ago. But in Michigan, some growers are already anticipating the spring resurgence of a tiny raptor that could benefit next season’s crop. As birds of prey, American kestrels deter smaller birds that like to snack on farmers’ fruit. New research shows they reduce the likelihood of cherry damage more than tenfold. But the study suggests that these winged security guards may have an additional benefit: food safety.
