Popularity runs in families

Science Daily - 07/06/2021
To investigate the role genes play in the evolution of social structure, researchers created an experiment they likened to the 1998 film 'The Truman Show.' Genetically identical versions of 20 fruit flies were placed in 98 controlled enclosures, and video cameras recorded their interactions. The study revealed the same clones occupied the same social positions in each enclosure, regardless of living conditions, providing evidence that popularity is heritable.

Applying mathematics takes 'friendship paradox' beyond averages

Science Daily - 07/06/2021
In network science, the famous 'friendship paradox' describes why your friends are (on average) more popular, richer, and more attractive than you are. But a slightly more nuanced picture emerges when we apply mathematics to real-world data.

Researchers identify a molecule critical to functional brain rejuvenation

Science Daily - 07/06/2021
A new study has identified a molecule called ten-eleven-translocation 1 (TET1) as a necessary component in the repair of myelin, which protects nerves and facilitates accurate transmission of electrical signals. The discovery could have important implications in treating neurodegenerative diseases and for molecular rejuvenation of aging brains in healthy individuals.

Pandemic prevention measures linked to lower rates of Kawasaki disease in children

Science Daily - 07/06/2021
Rates of Kawasaki disease -- a condition that creates inflammation in blood vessels in the heart and is more common in children of Asian/Pacific Island descent -- have substantially decreased in South Korea during the COVID-19 pandemic, according to a new study. The decrease could be due to mask-wearing, hand-washing, school closures and physical distancing, suggesting Kawasaki disease may be prompted by infectious agents.

How a Vietnamese raw pork snack could help us keep food fresh, naturally

Science Daily - 07/06/2021
Nem Chua is eaten raw but doesn't cause food poisoning when prepared correctly. Food scientists went to explore why - and discovered a powerful new bacteria-killer. A new study reveals the ideal growth conditions to potentially make the bacteriocin at industrial scales.

Controlling insulin production with a smartwatch
