Energy from the sun’s rays can cause skin damage and cancers. Sunscreens can absorb or reflect the dangerous UV light. Here’s ...

In 1895, a German scientist discovered what he called X-radiation, a form of ionizing electromagnetic radiation able to penetrate not only clothing and skin, but brick walls. Known today as ...

Standard indoor testing in a controlled environment, which continuously mimics sun irradiation, only serves as a proxy for real-world performance. Environmental conditions, such as varying light, ...

The evaporator achieves an impressive solar-vapor conversion efficiency, with an evaporation rate of 1.61 kg m⁻² h⁻¹ under one sun irradiation. In a 20% NaCl solution, it sustains a high evaporation ...

Reduced-Volume Irradiation of Uninvolved Neck in Patients With Nasopharyngeal Cancer: Updated Results From an Open-Label, Noninferiority, Multicenter, Randomized Phase III Trial The following ...

Prophylactic cranial irradiation (PCI) is radiation therapy used to prevent brain metastases in people with limited-stage small cell lung cancer.

The amount of sun irradiation has a significant impact on the energy produced by these arrays. The work being done made use of dual-axis solar monitoring that relied on comparing the amount of light ...

The gigantic coronal hole is more than 60 times wider than Earth. (Image credit: NASA/SDO/AIA) An enormous dark hole has opened up in the sun's surface and is spewing powerful streams of unusually ...
