Say goodbye to casts: “magic” material can heal your bones in mere days

Posted by in categories: biotech/medical, materials

Regrowing bones is no easy task, but the world’s lightest solid might make it easier to achieve. Researchers have figured out a way to use hybrid aerogels, strong but ultralight materials, to prompt new bone tissue to grow and replace lost or damaged tissue.

Although bone cancer is a relatively rare disease (it accounts for less than 1% of all cancers), people who suffer from it often end up losing a lot of bone tissue and, in extreme cases, undergo amputation. The cancerous tissue has to be cut out, taking with it a large chunk of nearby healthy tissue to make sure that the cancer does not spread. This effectively removes the cancer, but also leaves the patient with a lot less bone than they started out with.

Do you agree? 😁.


By now, it’s undeniable: regular exercise comes with a range of health benefits for people who stick with it over time. But is it ever too late to start?

Longevity And Health

Posted by in categories: biotech/medical, education, life extension, neuroscience

Education and bravery are the key to our survival. In this article we dig into the correlation between health and longevity.


With so many supplement salesman and scientists talking about longevity it can get confusing as to exactly what that might mean. Of course we all want to live as long as we can but most would agree to it only if they were able to be healthy and active. After all how would life be worth it if you were confined to a bed or wheelchair in constant pain?

As we improve health we also extend life. One drawback to extending life is that we face health problems we might have avoided by simply not being alive. However as we extend life we will also extend health and find ways to cure all diseases. For most of humanity throughout the ages Cancer or Alzheimer’s was rarely a cause for concern. Cancer and Alzheimer’s was not as prevalent because most people did not live long enough to be stricken with them. Many humans died from infections, starvation, and injury and thus the expected life span was much lower than today. Every time a new advancement is made in healthcare we improve the odds of living longer. Hospitals, handwashing, and vaccines all improved a human beings chance of survival and also their chance of contracting a new or otherwise unusual disease.

From a cloud of cold and a spark, researchers create and stabilize pure polymeric nitrogen for the first time

Posted by in categories: materials, particle physics

Scientists have long theorized that the energy stored in the atomic bonds of nitrogen could one day be a source of clean energy. But coaxing the nitrogen atoms into linking up has been a daunting task. Researchers at Drexel University’s C&J Nyheim Plasma Institute have finally proven that it’s experimentally possible—with some encouragement from a liquid plasma spark.

Reported in the Journal of Physics D: Applied Physics, the production of pure polymeric nitrogen—polynitrogen—is possible by zapping a compound called sodium azide with a jet of plasma in the middle of a super-cooling cloud of liquid nitrogen. The result is six nitrogen atoms bonded together—a compound called ionic, or neutral, nitrogen-six—that is predicted to be an extremely energy-dense material.

“Polynitrogen is being explored for use as a ‘green’ fuel source, for energy storage, or as an explosive,” said Danil Dobrynin, Ph.D., an associated research professor at the Nyheim Institute and lead author of the paper. “Versions of it have been experimentally synthesized—though never in a way that was stable enough to recover to ambient conditions or in pure nitrogen-six form. Our discovery using liquid plasma opens a new avenue for this research that could lead to a stable polynitrogen.”
