Researchers from North Carolina State University have identified a microRNA (miRNA) that could promote hair regeneration. This miRNA – miR-218-5p – plays an important role in regulating the pathway involved in follicle regeneration, and could be a candidate for future drug development.

Hair growth depends on the health of dermal papillae (DP) cells, which regulate the hair follicle growth cycle. Current treatments for hair loss can be costly and ineffective, ranging from invasive surgery to chemical treatments that don’t produce the desired result. Recent hair loss research indicates that hair follicles don’t disappear where balding occurs, they just shrink. If DP cells could be replenished at those sites, the thinking goes, then the follicles might recover.

A research team led by Ke Cheng, Randall B. Terry, Jr. Distinguished Professor in Regenerative Medicine at NC State’s College of Veterinary Medicine and professor in the NC State/UNC Joint Department of Biomedical Engineering, cultured DP cells both alone (2D) and in a 3D spheroid environment. A spheroid is a three-dimensional cellular structure that effectively recreates a cell’s natural microenvironment.

In a new study, the scientists claimed to have found the answer to one of the most baffling questions in the history of humankind — ‘What came first: Chicken or the egg?’. The question has to date left everyone, from scholars to schoolchildren, stumped. However, scientists now claim to have discovered the answer.

As per the researchers from the University of Bristol, the early ancestors of reptiles and modern birds are likely to have given birth to live young and may have not laid eggs, according to The Times. The Journal Nature Ecology and Evolution published the study which detailed the discovery.

Scientists, along with researchers from Nanjing University, have challenged the belief which existed so far that hard-shelled eggs were the reason for the success of amniotes, which are animals whose foetuses are developed inside an amnion (membrane or sack) inside the egg.

As part of our own recent AI hackathon, the NFX content team spent 48 hours going from house to house, office to office, talking with top founders about their work — what’s hard, what’s exciting, and what will never be the same again. What’s really happening day in and day out at hacker houses and AI social clubs is electric and an entirely new way of thinking and building. This is the rise of the AI underground.
