Controlling Light With Light
A breakthrough in rapid polarization switching with an all-optical polarization control could allow faster data transfer and open new areas of nanoresearch, enabling researchers to learn more about unseen nanoscale worlds such as drug chemistry and quantum electronics. Scientists have developed an ultrafast method of changing the fundamental properties of light with light.

Light and Moisture Combine to Mend Defects in Perovskite Films
Exposure to light combined with exposure to humidity and oxygen has been shown to permanently correct defects in the molecular structure of perovskites, resulting in minimal nonradiative losses and properties approaching those of perovskite single crystals and crystalline semiconductors. To repair defects caused by carrier trapping, researchers developed a perovskite-based device, and before completing it, exposed it to light, oxygen and humidity.

Ballistic Photon Imaging Locates Fiber Optic Instruments In Vivo
A camera that detects light sources inside the human body could be used at a patient’s bedside to track and guide the location of an endoscope, or other fiber optic instrument, in the body without the need for x-rays or other equipment. The high absorption and scattering of light in the visible spectrum has traditionally made it difficult for light-based devices to provide information about tissue layers beyond a depth of a few millimeters under the skin.

Photorealistic 3D Renderings Accurately Digitize Transparent Objects
The ability to create detailed, 3D digital versions of clear objects and their surroundings has been difficult because of the different modalities required to digitize objects with diffuse reflectance properties. Scientists have created a new imaging technique that could be useful for movie production, creating virtual reality experiences, improving design and quality assurance in the production of clear products, and even for preserving rare or culturally significant objects.

Photosensitizer Activates Anti-Cancer Properties in Antimalarial Drug
Scientists have shown that the anticancer properties of artemisinin, an antimalarial drug that is also a promising alternative cancer treatment, could be enhanced potentially tenfold when used with the photosensitizer aminolaevulinic acid (ALA). When exposed to light, ALA leads to the generation of free radicals that can kill cells. A combination of artemisinin and ALA could kill colorectal cancer cells and suppress tumor growth more effectively than administering artemisinin alone.
