Particles of light can spend "negative time" passing through a cloud of extremely cold atoms – without breaking the laws of ...

Image caption, LEFT: The structure of diamond showing each carbon atom joined to four others. RIGHT: The structure of graphite with atoms of carbon arranged in layers. Carbon fibres are long ...

Carbon tax. Carbon footprint. Carbon emissions. Carbon is in the news every day, so you’d think we’d know everything about it — but you’d be wrong. Carbon could be the most misunderstood ...

Scientists in China have developed a tensor processing unit (TPU) that uses carbon-based transistors instead of silicon – and ...

It is made from carbon, oxygen, and hydrogen atoms. Carbon dioxide is made from one carbon atom and two oxygen atoms. The molecules of carbon dioxide are thoroughly mixed and dissolved into the water ...

However, the development of reagents that can selectively introduce a carbon atom is a challenging task. Professor Max ...

An individual atom of a biologically important element, such as carbon, may have spent 65 million years buried as coal before being burned in a power plant, followed by two decades in Earth's ...

The original version of this story appeared in Quanta Magazine. In 1896, the Swedish physicist Svante Arrhenius realized that carbon dioxide (CO 2) traps heat in Earth’s atmosphere—the ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

Carbon dioxide (CO 2) comes from both natural sources (including volcanoes, the breath of animals and plant decay) and human sources (primarily the burning of fossils fuels like coal, oil and natural ...

But what makes oxygen different from carbon? It is the number of protons in the nucleus of an atom that is the defining feature of the atom. It's what makes one element different from another.
