Certain combinations of medication or psychotherapy with transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) are supported by clinical studies for major depressive disorder (MDD) treatment. Researchers recommend more sophisticated trial designs to move the field forward.

Cloudy waters causes African fish to develop bigger eyes

Researchers found that young African fish raised in cloudy water developed larger eye structures than those raised in clear water. As the fish age, they lose this ability to adapt. The study also showed that older fish have bigger brains and optic lobes, suggesting different sensory demands at various stages of life.
