Scientists can 3D print human heart tissue now. The future is here

July 10th, 2018 at 10:41 am » Comments Off

Long term, the goal of 3D bioprinting is to be able to 3D print fully functioning organs which can be used to replace the failing biological organs of humans in need of a transplant. That may still be years off, but Chicago-based biotech startup Biolife4D this week announced a major new milestone: Its ability to […]

Thousands of Swedes are choosing to have microchips inserted into their bodies. Here’s why

June 27th, 2018 at 9:09 am » Comments Off

Thousands of people in Sweden have inserted microchips, which can function as contactless credit cards, key cards and even rail cards, into their bodies. Once the chip is underneath your skin, there is no longer any need to worry about misplacing a card or carrying a heavy wallet. But for many people, the idea of […]

These robots use living muscle tissue to mimic human fingers

June 5th, 2018 at 9:45 am » Comments Off

As if the line between human and machine wasn’t already blurry enough, researchers in Tokyo have developed a new method for using living rat muscle tissue in robotics. The “biohybrid” design, described today in the journal Science Robotics, simulates the look and movements of a human finger. Video shows how it bends at the joint, […]

Japan approves first trials of stem cell-based heart treatment

May 17th, 2018 at 10:16 am » Comments Off

iPS procedure raises hopes for alternative to donations and artificial organs TOKYO — Japan is set to host the world’s first clinical trials involving the use of induced pluripotent stem (iPS) cells to treat heart failure. A special health ministry panel on Wednesday gave Osaka University the green light to carry out the study, pending […]

What Is Bioprinting?

May 11th, 2018 at 10:14 am » Comments Off

Bioprinted materials can be used to repair damaged organs. Bioprinting, a type of 3D printing, uses cells and other biological materials as “inks” to fabricate 3D biological structures. Bioprinted materials have the potential to repair damaged organs, cells, and tissues in the human body. In the future, bioprinting may be used to build entire organs […]

Gene editing for good

How CRISPR could transform global development. Today, more people are living healthy, productive lives than ever before. This good news may come as a surprise, but there is plenty of evidence for it. Since the early 1990s, global child mortality has been cut in half. There have been massive reductions in cases of tuberculosis, malaria, […]

End of ageing and cancer? Scientists unveil structure of the ‘immortality’ enzyme telomerase

April 29th, 2018 at 9:36 am » Comments Off

  Making a drug is like trying to pick a lock at the molecular level. There are two ways in which you can proceed. You can try thousands of different keys at random, hopefully finding one that fits. The pharmaceutical industry does this all the time – sometimes screening hundreds of thousands of compounds to […]

Decoding your baby’s DNA: It can be done. But should it be?

Maverick Coltrin was diagnosed with pyridoxine-dependent epilepsy shortly after he was born. He now gets checkups to make sure his seizures are under control and that he’s still healthy. (Kent Nishimura / Los Angeles Times) Maverick Coltrin entered the world a seemingly healthy 8-pound boy. But within a week, he was having seizures that doctors […]
