Curiosities of medical history: Trepanation

Neurosurgery as we know it today only started to develop in the late 19th century. However, interventions that required drilling a hole in the skull, now known as “trepanation,” are much older. When did humans first perform these procedures, and why? Why did our ancestors drill holes into the skull?Image credit: Wellcome Collection The term […]

Scientists identify genetic components of left-handedness

Scientists identify genetic components of left-handedness

For the first time, scientists have pinpointed regions of human DNA that closely relate to whether people are right- or left-handed. They also linked these regions to language-related features in the brain. New research pinpoints the genes associated with left-handedness. Previously, scientists knew that genes were responsible for around 25% of handedness. However, before the […]

World first: Doctors use ‘reprogrammed’ stem cells to repair cornea

World first: Doctors use ‘reprogrammed’ stem cells to repair cornea

Scientists in Japan have, for the first time, treated a damaged cornea using induced pluripotent stem cells. According to the surgeon, the person’s vision has improved since the procedure. The cornea covers the front section of the eye, including the iris and pupil. Scientists create induced pluripotent stem (iPS) cells by reprogramming adult cells. This […]

Inflammation in late teens linked to mortality risk decades later

Inflammation in late teens linked to mortality risk decades later

Using data from more than 100,000 males and spanning more than 3 decades, a new study investigates the long term effect of inflammation in early adulthood. Could inflammation in early adulthood influence disease risk more than 30 years on? Inflammation is part of the body’s natural response to harmful stimuli, such as irritants, damaged cells, […]

Occipital Neuralgia (Headache)

What is occipital neuralgia? Occipital neuralgia is a form of headache that causes pain along the upper neck and back of the head. The pain is in the distribution of the nerves known as occipital nerves (sensory nerves that run from the upper part of the neck to the back of the head). The pain […]
