Study reveals cirrus cloud traits over the South China Sea

The radiative climate and environmental effects of cirrus clouds is an international cutting-edge field of scientific research in the atmospheric sciences. Understanding how the characteristics of cirrus clouds over the ocean ...

Short commercial space flights may not have big impact on health

The first all-civilian space mission is shedding light on the potential health risks facing private astronauts. The takeaway is short-duration spaceflights appear to pose none that are significant. The study sample was small—four ...

Study identifies fungus that breaks down ocean plastic

A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers from, among others, NIOZ published their results in the journal Science of ...

Radiation

In physics, radiation describes any process in which energy emitted by one body travels through a medium or through space, ultimately to be absorbed by another body. Non-physicists often associate the word with ionizing radiation (e.g., as occurring in nuclear weapons, nuclear reactors, and radioactive substances), but it can also refer to electromagnetic radiation (i.e., radio waves, infrared light, visible light, ultraviolet light, and X-rays) which can also be ionizing radiation, to acoustic radiation, or to other more obscure processes. What makes it radiation is that the energy radiates (i.e., it travels outward in straight lines in all directions) from the source. This geometry naturally leads to a system of measurements and physical units that are equally applicable to all types of radiation.
