DNA-protein cross-links promote cGAS-STING–driven premature aging and embryonic lethality - Science | AAAS

Neutrophils are white blood cells that form part of the body's first line of defence. Researchers have now demonstrated for the first time that neutrophils are found in many tissues during embryonic development, and that they can perform the same functions as adult neutrophils. The findings warrant further study on the role of embryonic neutrophils in tissue development and in responding to infections in fetuses and newborns. Neutrophils are part of innate immune defence. When inflammation occurs, they rapidly migrate from the bloodstream into tissues to eliminate harmful microbes. Their role is well understood in adults, but remarkably little is known about embryonic neutrophils.

Voltage fluctuations, light fluctuations, temperature fluctuations—any fluctuations are troublesome and thus undesirable. They don't just cause discomfort; in engineering and medical applications, they affect the accuracy of measurements or introduce errors in controls. Even at the minute level of quantum phenomena, fluctuations are considered undesirable. But what if some fluctuations can be made useful? A theoretical study from the Indian Institute of Technology Bombay (IIT Bombay) shows that structured quantum fluctuations in light can be used to sense and generate useful quantum optical signals.

Schematic model for the origin of isotopic anomalies in ocean island basalts. Credit: Science Advances (2026). DOI: 10.1126/sciadv.aei4756 When Earth formed billions of years ago, its metallic core was wrapped in a global ocean of molten rock, which eventually cooled and crystallized to form the mantle. Today, when deep-rooted mantle plumes rise toward the surface and produce volcanic eruptions, the resulting lava can contain hydrogen from deep inside the planet.
