"Founder events" that reduced genetic diversity found to be common throughout human history

Human populations have waxed and waned over the millennia, with some cultures exploding and migrating to new areas or new continents, others dropping to such low numbers that their genetic diversity plummeted.

New model outlines how neural circuits learn to control the body from early, spontaneous movements

Does the nervous system come with instructions for how it should connect to the body or must it figure this out during early development? A new model from researchers at the University of Southern California and Lund University in Sweden suggests that spontaneous movements made by a fetus in the womb (including those kicks) are a key step in getting the body's nervous system "wired up."

Mathematical model helps predict the risk of COVID-19 transmission in a train carriage

Researchers have demonstrated how airborne diseases such as COVID-19 spread along the length of a train carriage and found that there is no 'safest spot' for passengers to minimise the risk of transmission.

Evidence-based study shows how hypnotherapy provides positive outcomes for IBS patients

It is common that Hong Kong people might have experiences of disordered defecation with unknown reason, such as diarrhea and constipation. It is also easy to observe that abdominal discomforts often come along with stress. Emotion disturbance and stress might affect our intestinal functions.
