A team of scientists has made a groundbreaking discovery that challenges the long-held assumption about oceanic iron cycles. They found that organic compounds can capture some iron spewed by hydrothermal vents, enabling it to be carried away in seawater and reaching the surface, where it can nourish marine life more efficiently.
Researchers found that BDNF treatment can prevent or reverse memory loss, cognitive impairment, and brain cell degeneration in animal models of Alzheimer's disease. The study suggests a potential novel approach to treating the disease by slowing its progression.
A new study reveals that the chemical mediator sphingosine-1-phosphate plays a crucial role in maintaining bone balance. Researchers found that mice with functional S1P receptors had denser bones than those without, suggesting a potential target for treating bone-resorptive disorders.
A large international study identified nine genetic regions linked to increased risk of early-onset myocardial infarction. The study analyzed data from 26,000 individuals in 10 countries and found significant associations with common single-nucleotide polymorphisms (SNPs) in nine genetic regions.
Scientists have created a microchip that uses 30 times less electricity while running seven times faster than today's technology, thanks to probabilistic logic. This technology has significant implications for the IT industry's carbon footprint, potentially reducing energy consumption in devices such as cell phones and medical implants.
A study at Columbia University Medical Center found that experimental heart failure drugs may slow muscle loss in Duchenne muscular dystrophy, a fatal genetic disorder. The new class of drugs targets the same microscopic leak that weakens both skeletal and cardiac muscles.
Researchers have identified two proteins, dynein and Nudel, as crucial for regulating the assembly of the spindle matrix during mitosis. This finding broadens our understanding of how cells control critical events during division. Understanding spindle assembly is essential to comprehend cell fate choices and development.
Experts discuss new biotechnology techniques to remove fungus, micro-organisms, and insects from artwork, documents, and masonry, promoting natural and non-toxic preservation methods. Curators in developing countries face challenges in assessing vulnerability, improving storage conditions, and controlling environmental fluctuations.
A University of Minnesota-led study connects iron sources from extreme depths to surface life, shedding light on nutrient cycling. Researchers found that hydrothermal vents release rusty iron, which can provide essential nutrients for sea life.
A new Northwestern University study uses brain-reading technology to show that people can be more accurate in recognizing familiar images when distracted or guessing than when paying full attention. The research suggests that implicit recognition may play a significant role in everyday decision-making and problem-solving.
Researchers at Scripps Institute successfully capture the crystal structure of an intermediate viral particle, revealing a dynamic process of protein coat assembly. The study provides fresh insights into viral protein interactions and suggests potential targets for interrupting virus assembly.
Young southern right whales learn from their mothers where to feed in the ocean, but researchers worry they may not be able to adapt if food sources become scarce due to global warming.
