Self-healing plastic mimics blood clotting

READ MOREHealing chemicals arrive via capillaries (the red and blue vertical lines) and form a gel that seals the gap

Science of Materials

A new plastic that "heals itself" has been designed, meaning your cracked phone screen or broken tennis racquet could mend its own wounds.

The polymer automatically patches holes 3cm wide, 100 times bigger than before.

Inspired by the human blood clotting system, it contains a network of capillaries that deliver healing chemicals to damaged areas.

The new material, created by engineers at the University of Illinois, isdescribed in Science journal.

For decades scientists have dreamed of plastics that heal themselves like human skin.

Cracks in water pipes and car bonnets would seal up. Satellites could repair their own damage. Broken electronic chips in laptops and mobile phones would spontaneously sort out their own problems.

Black Death skeletons give up secrets of life and death

READ MOREThe medieval Black Death led to better health for future generations, according to an analysis of skeletons in London cemeteries. Tens of millions of people died in the epidemic, but their descendants lived longer and had better health than ever before, a study shows. The Black Death was one of the most devastating epidemics in human history. But survivors benefited from rising standards of living and better diets in the aftermath of the disaster. The improvements in health only occurred because of the death of huge numbers of people, said a US scientist. It is evidence of how infectious disease has the power to shape patterns of health in populations, said Dr Sharon DeWitte of South Carolina University. Continue reading the main story “ Start Quote Even in the face of major threats to health, such as repeated plague outbreaks, several generations of people who lived after the Black Death were healthier in general than people who lived before the epidemic” Dr Sharon DeWitte University of South Carolina Lumps and black spots The Black Death killed 30-to-50% of the European population in the 14th Century, causing terror as victims broke out in lumps and black spots, then died within days. The elderly and the sick were most at risk of catching the bacterial infection, which was probably spread through sneezes and coughs, according to the latest theory. The outbreak had a huge impact on society, leaving villages to face starvation, with no workers left to plough the fields or bring in the harvest. However, despite analysis of historical records, little is known about the general health and death rates of the population, before and after the disease struck.

REALITY?

Reality is a strange thing.Why you ask.Well when you watch television ,films you suspend your belief -aliens being beaten up by weird costumed superheros,or a soap chartacter reacting a scene seen many a time before.It has been said that one mans reality is anothers insanity so is this post reality.
