Three ingots from the site of Los Escoriales de Do a Rama (Belmez) and dating from the Roman era demonstrate the importance of lead production and exportation in northern Cordoba.
Turbid waters keep the coast healthy
To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study.
DDT pollutants found in deep sea fish off Los Angeles coast
As the region reckons with its toxic history of offshore dumping off the California coast, new findings raise troubling questions about whether the banned pesticide remains a threat to wildlife and human health.
Geologists, biologists unearth the atomic fingerprints of cancer
Earth scientists have long turned to minute differences in hydrogen atoms to explore the ancient history of our planet. A new study suggests that these same tiny atoms might also lead to new ways to track the growth of cancer.
Quantifying U.S. health impacts from gas stoves
A new study of air pollution in U.S. homes reveals how much gas and propane stoves increase people's exposure to nitrogen dioxide, a pollutant linked to childhood asthma. Even in bedrooms far from kitchens, concentrations frequently exceed health limits while stoves are on and for hours after burners and ovens...
Aligned peptide ‘noodles’ could enable lab-grown biological tissues
Researchers have developed peptide-based hydrogels that mimic the aligned structure of muscle and nerve tissues, which could enable the development of functional lab-grown tissue.
Sister cities can help communities better navigate the climate crisis
Anthropologists suggest in a new study that establishing networks of 'sister cities' dedicated to addressing the impact of natural disasters can mitigate the devastation wrought by climate change.
Genomes of ‘star algae’ shed light on origin of plants
Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms....
Did a magnetic field collapse trigger the emergence of animals?
Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts...
Birdwatching can help students improve mental health, reduce distress
A new study finds people who have nature-based experiences report better well-being and lower psychological distress than those who do not. Birdwatching in particular yielded promising results, with higher gains in subjective well-being and more reduction in distress than more generic nature exposure, such as walks. Because birdwatching is an...
