“Forever Chemicals” Disrupt Key Biological Processes

A team of researchers from the Keck School of Medicine of USC found that exposure to a mixture of synthetic chemicals found widely in the environment alters several critical biological processes, including the metabolism of fats and amino acids, in both children and young adults. The disruption of these biological processes is connected to an increased risk of a very broad range of diseases.

A Different Slant of Light

Special cells in giant clams shift the wavelength of light to protect them from UV radiation and increase the photosynthetic activity of their symbionts, show research from Kaust—originally intended as a photonics investigation.
