New research reveals human-made organic chemicals (xenobiotics) make up a significant portion of dissolved organic matter in coastal oceans. The study published in Nature Geoscience combined and analysed 21 public mass spectrometry datasets containing information on dissolved organic molecules present in more than 2,300 seawater samples. The samples were collected from coastal and open ocean environments across the central and eastern Pacific, Indian and North Atlantic oceans. Common [...]

Babies exposed to poverty show delays in motor development as early as 6 months old, but identifying risks and intervening early can reverse these effects. A Brazilian study followed 88 babies, 50 of whom from families experiencing socioeconomic vulnerability, from ages 3 to 8 months. The researchers used an approach called the “Infant Motor Profile” to assess motor development, analysing factors such as a baby’s repertoire of movement patterns, smoothness and coordination of [...]

Researchers in Brazil created a flexible and transparent biofilm from fish skin that could be used in food packaging, pharmaceuticals and biomedical products in the place of synthetic plastics. “We’ve been working for over 25 years on the development of films based on biopolymers, such as proteins and polysaccharides, with the aim of applying this material to food packaging and reducing the environmental impact, since there are many problems associated with the accumulation of synthetic [...]
