UMN researchers give new insight to muscular dystrophy patients
New research by University of Minnesota scientists has revealed the three dimensional structure of the DUX4 protein, which is responsible for the disease, facioscapulohumeral muscular dystrophy (FSHD). Unlike the majority of genetic diseases, FSHD is not caused by a protein that is missing or not functioning properly. Rather it is caused when a functioning, normal, protein shows up in a place where it doesn't belong (in muscles). (2018-12-12)

Hair colour gene study sheds new light on roots of redheads' locks

The use of electrospun scaffolds in musculoskeletal tissue engineering
Rotator Cuff tears affect 15 percent of 60 year olds and carry a significant social and financial burden. Current operative techniques and repair adjuncts are associated with unacceptably high failure rates, stimulating investigation into novel tissue engineering and regenerative medicine (TERM) approaches in the field of rotator cuff surgery. In this review researchers explore the most recent advances in the field of electrospinning, focussing on proposed tissue-engineered solutions in tendon, specifically the rotator cuff. (2018-12-10)

Not in the DNA: Epigenetics discovered in single-celled archaea
Researchers have reported the first experimental evidence of epigenetics in the single-celled organisms known as archaea. The simplicity of archaea -- combined with the fact that their cells resemble eukaryotes' in some important ways -- may allow researchers to investigate epigenetic questions in humans much faster and more easily than was possible before, the authors say.

A bastard seal from the past reveals the potential for human hybrids
If discovered as fossils, grey and ringed seals are so different that they could be classified as belonging to different families. Yet, a seal pup born in 1929 was found to be an almost perfect intermediate between the species. Compared to Neanderthals and modern humans, grey and ringed seals are genetically and dentally at least twice as different, suggesting that there may be more fossil human hybrids to be discovered.

Physicists train robotic gliders to soar like birds
Scientists know that upward currents of warm air assist birds in flight. To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings also provide a navigational strategy that directly applies to the development of UAVs. (2018-09-19)

Study highlights genetic risk of heart failure
Heart failure is known to be more common in certain families but whether this familial transition is caused by genetic or lifestyle factors. By studying adoptees in relation to both their biological parents and adoptive parents, a new population study in Sweden has found that genetic heritage is the dominant factor when it comes to heart failure in these families.

Cells stop dividing when this gene kicks into high gear, study finds
Scientists seeking to unlock secrets of cellular aging have identified a gene that triggers senescence, a phenomenon in which cells stop dividing. The gene, called CD36, is unusually active in older, senescent cells. Heightening CD36 activity also caused young, healthy cells to stop dividing, with the effect also spreading to nearby cells in the same petri dish. (2018-06-21)
