New Technique For Regenerating Heavily Injured Muscles

by Agnese Mariotti in United Academics

Current therapies of heavily injured muscles imply surgical removal of the scar tissue and transplantation of immature muscles cells. Unfortunately, the transplanted cells are often unable to survive after transfer into patients. Now scientists bypassed this problem by providing the damaged tissue only with a biological scaffold of Extracellular Matrix (ECM). The results are promising.... Read more »

Finally Solved: Why Zebra’s Wear Black And White Stripes

by Chiara Civardi in United Academics

The origin of zebra stripes has long been a mystery: in over a century, scientists developed various hypotheses. Social factors, cooling mechanisms and camouflage against predators, were proposed as possible explanations. However, no striking evidence could support one particular theory, so the black and white striping in zebra was believed to remain a grey area.... Read more »

by Harsha Radhakrishnan in United Academics

Growth of biomedical research simultaneously hinders and advances its development.

This week brought to the forefront two important pieces of news in the field of biomedical research. Bad news first – the future of biomedical research looks bleak if things are not going to change. Then the good news – depending on your views on science, this second bit could be either head-scratching or eye opening: Scientists in the Scripps Research Institute, following years of research, have been able to create a synthetic organism with an “artificial DNA”....
