An accounting of Africa’s water resources reveals a gap in water management, according to Nature. The finding matters because reliable water data and stronger management are needed for planning, sustainability, and responding to scarcity.
Research published in Nature shows that the human brain eliminates billions of neurons with mutations around the time of birth. This process appears to be a normal part of brain development and may help explain how the brain refines its circuitry. The findings could inform understanding of developmental brain disorders.
Researchers report a chemical method that converts silicones back into their monomer building blocks using deoxygenative chlorination. The approach could make silicone materials easier to recycle instead of disposing of them. It matters because silicones are widely used but difficult to break down chemically.
Researchers have found that lactate can enter heart-cell mitochondria through a shortcut pathway, where it is used to power cardiac energy production. The finding challenges assumptions about how lactate is metabolized and may help explain or inform treatment of heart failure and metabolic heart disease.
New research offers clues as to why dengue virus can still infect people who have been vaccinated, according to Nature. The findings could help explain breakthrough infections and inform work on more effective dengue vaccines. Dengue infects hundreds of millions of people each year, and vaccine protection has proven uneven across the four virus serotypes.
Researchers are taking seriously the idea of placing a giant sunshade in space to block some sunlight and cool the planet. The concept is a form of solar geoengineering that could theoretically address global warming but raises major feasibility, governance and environmental questions.
A meta-study raises questions about whether commonly used measures capture what it means to be good at regulating emotions. The findings could affect how psychologists assess emotional health and design interventions.
New findings show that genetic variants shape chromatin accessibility in specific cell types, linking cell-type-specific gene regulation to disease. This helps explain how noncoding risk variants act and improves interpretation of disease genetics.
Researchers have freshly cultivated archaea that provide new clues about how complex life may have evolved. The work could help clarify the biological transitions that led from simple microbes to eukaryotes. It matters because it sheds light on a central question in evolutionary biology.
