Quantum dots are tunable semiconductor nanocrystals that enable precise control of light absorption and emission for diverse ...

Explore 25 astonishing things you can only see under a microscope. Discover hidden universes in everyday objects, from ...

A kilogram of iron sulfate costs pennies. A kilogram of platinum costs tens of thousands of dollars. Both metals can help ...

Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds ...

Invisible "dark matter"—what cosmologists call the mysterious glue that holds everything together—is estimated to make up ...

Measurements of this interstellar comet’s molecular makeup show an excess of heavy water molecules that is dramatically ...

A new approach reveals unexpected ways oxygen can bind to rare metals. Iron plays a central role in how the body uses oxygen. In hemoglobin, it binds dioxygen, a pair of oxygen atoms, allowing blood ...

A new study finds that in low-oxygen environments, red blood cells absorb more glucose and convert it into a molecule that helps release oxygen into tissues, revealing an unexpected way the body ...

On a breezy afternoon last autumn in Cambridge, Mass., in a laboratory thrumming with the huff-whish-huff sound of ...

In this study, the authors use microCT to image an intact hatchling octopus and segment major organ systems, including the vascular, respiratory, digestive, and nervous systems. The resulting dataset ...

Oxygen is a non-metal element that is a gas at room temperature. Its molecules contain two oxygen atoms. Oxygen is vital for respiration, which is the process that transforms energy from glucose to ...

Exposure to high-altitude hypoxia is associated with an increased risk of impaired brain structure and function, with oxidative stress and neuroinflammation widely recognized as key mechanisms ...
