What if one of the world’s most overlooked waste products could be turned into a valuable resource? A team of researchers led by Stanford University has developed a new system that does just that—transforming urine into fertilizer and renewable energy. Their prototype, recently published in Nature Water, shows how human waste can become a powerful tool for farming, sanitation, and sustainability, especially in parts of the world where resources are limited. For decades, [...]

A new Zika virus vaccine developed in Brazil by researchers at the Institute of Tropical Medicine of the University of São Paulo's Medical School (IMT-FM-USP) has been shown to be safe and effective in tests with mice. In addition to inducing an immune response against the pathogen, the vaccine also protected the animals from the brain and testicular damage typically caused by viral infection. The findings were published in the scientific journal NPJ Vaccines and [...]

Engineers have designed a system that uses electricity and waste heat generated by solar panels to extract nitrogen fertiliser from human urine, leaving behind clean wastewater which is safer to discharge or reuse for irrigation. The proof-of-concept photovoltaic–thermal electrochemical stripping (ECS) system, known as solar-ECS, has been published in a paper in Nature Water. “This project is about turning a waste problem into a resource opportunity,” says study senior [...]

An international team of around 100 researchers from over 70 institutions has established standardized guidelines for analyzing oxylipins using liquid chromatography with mass spectrometry. Oxylipins are bioactive lipids derived from fatty acids that play central roles in physiological and pathological processes, including inflammation, immunity, cancer, and neurodegenerative and cardiovascular diseases. The guidelines were developed by Valerie O'Donnell of Cardiff University in the [...]

A groundbreaking study by ethnobotanist Hemerson Dantas dos Santos Pataxó Hãhãhãi has revived the ancestral healing knowledge of his indigenous people. Currently a doctoral student at the Institute of Environmental, Chemical, and Pharmaceutical Sciences at the Federal University of São Paulo (ICAQF-UNIFESP) in Brazil, he belongs to the Pataxó Hã-Hã-Hãi people. According to his doctoral advisor, Eliana [...]

Near the Syrian city of Afrin, an international research team, including researchers from the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen, has discovered a previously unknown fossil sea turtle. The species Syriemys lelunensis, newly named under the aegis of the University of São Paulo, dates from the early Eocene, around 50 million years ago. The find includes a completely preserved interior impression of the shell as well as parts of [...]

In the selection of specialty coffees, those that score above 80 points in blind tests are free of physical and sensory defects. Greenish-colored beans are known to give the drink an astringent taste, which is described as harsh, pungent, and dry. These beans are therefore discarded, along with broken, black, burnt, pitted, or undersized beans. However, in a study published in the journal Food and Bioprocess Technology, researchers from the Federal University of Uberlândia [...]

Scientists working in the Brazilian coffee producing region of Minas Gerais may have uncovered a new way to increase the quality of immature beans to the level of specialty coffee. Researchers from the Federal University of Uberlândia (UFU) in Patos de Minas conducted a series of fermentations with both ripe and unripe Arara cultivar cherries. The experiment involved placing freshly harvested coffee cherries into 200-litre polystyrene barrels, which were then hermetically sealed for [...]

Researchers at the Optics and Photonics Research Center ( CePOF ) have succeeded in increasing the susceptibility of the fungus Candida albicans to drug treatment through light-activated therapy. The results of the study offer a promising alternative in the fight against antimicrobial resistance, a growing global problem that occurs when bacteria, viruses, fungi, and other parasites develop genetic mutations that render them resistant to drugs. In the [...]
