Detecting trace amounts of multiple classes of antibiotics in foods

Widespread use of antibiotics in human healthcare and livestock husbandry has led to trace amounts of the drugs ending up in food products. Long-term consumption could cause health problems, but it’s been difficult to analyze more than a few antibiotics at a time because they have different chemical properties. Now, researchers reporting in ACS’ Journal […]

Study finds rising rates of food insecurity among older adults

From 2007 to 2016, food insecurity–or limited access to nutritious foods because of a lack of financial resources–increased significantly from 5.5% to 12.4% among older US adults, and the increase was more pronounced among individuals with lower income. The findings come from a study published in the Journal of the American Geriatric Society. The study, […]

The leaf discs are preserved in a solvent that prevents degradation of clovamide, allowing large-scale… view more  Credit: Ben Knollenberg/Penn State The finding of relatively high levels of the antimicrobial compound clovamide in the leaves of a disease-resistant strain of […]

Drinking milk while breastfeeding may reduce the child’s food allergy risk

Children of mothers who drink relatively more cow’s milk during breastfeeding are at reduced risk of developing food allergies. That is the conclusion of researchers from Chalmers University of Technology, Sweden, in a new study published in the scientific journal Nutrients. The result is based on a survey of more than 500 Swedish women’s eating […]

Fishing alters fish behaviour and features in exploited ecosystems

IMAGE: Labrus bergylta spotted morphotyp view more  Credit: Olga Reñones Not all specimens of the same species are the same: there is a marked variability within the same population and sometimes these morphological differences are translated into a different behaviour. A study by the UB shows that fishing alters resource distribution and therefore, the behaviour of […]
