Body organs such as kidneys, livers and hearts are incredibly complex tissues. Each is made up of many different cell types, plus other components that give the organs their structure and allow them to function as we need them to.

For 3D printed organs to work, they must mimic what happens naturally – both in terms of arrangement and serving a biological need. For example, a kidney must process and excrete waste in the form of urine.

Our latest paper shows a new technique for 3D printing of cells and other biological materials as part of a single production process. It’s another step towards being able to print complex, living structures.

For every month in space, astronauts can lose 2.5 percent of their bone density. This is quite troublesome, as it will likely compound with the natural process of aging that also reduces bone density. However, a new therapy could be a fantastic solution to this issue, along with many other bone-weakening conditions.

Researchers from University College London have discovered that stem cells found in human amniotic fluid could be used in a treatment to strengthen brittle bones. The research, published in Scientific Reports, shows the treatment resulted in 79 percent fewer fractures in mice with brittle bone disease. Out of a total 324 mice, 168 were treated, while 156 served as the control group. Eight weeks after the mice were treated both the test group and the control group were evaluated for fractures.

Every control mouse exhibited fractures. Conversely, fractures in the experimental group decreased between 69 and 89 percent, leading to the 79 percent decrease in the fracture rate across all tested bones. Pascale Guillot, the study leader, found that the treatment was not resulting in new bone formation, but instead helping to fortify existing bone tissue.

The rapid development of so-called NBIC technologies – nanotechnology, biotechnology, information technology and cognitive science – are giving rise to possibilities that have long been the domain of science fiction. Disease, ageing and even death are all human realities that these technologies seek to end.

They may enable us to enjoy greater “morphological freedom” – we could take on new forms through prosthetics or genetic engineering. Or advance our cognitive capacities. We could use brain-computer interfaces to link us to advanced artificial intelligence (AI).

Nanobots could roam our bloodstream to monitor our health and enhance our emotional propensities for joy, love or other emotions. Advances in one area often raise new possibilities in others, and this “convergence” may bring about radical changes to our world in the near-future.

DNA testing is not new to consumers, but it’s a one-shot deal. You send in your sample, then you get to see ancestry and health data provided by the company you chose to use for testing. Some new insights might be added over time, but there’s not much else you can do with that genetic data. A startup called Helix is counting on people being curious enough to drop cash in its DNA app store on a regular basis. The initial testing costs $80, and after that you can buy the applications you want.

Helix uses a type of genetic testing called DNA sequencing. Other companies like 23andme are using the far simpler genotyping; Helix is actually finding the pattern of nucleic acids (using flow cells like the one above) in your DNA for around 20,000 different genes, known as the exome. A genotyping test only tells you which variant you have of specific genes, so a full sequence generates about 100 times as much data. Helix is taking this approach because the company is not deciding what sort of data to show users. Instead, that’s all up to third-parties that decide to sell DNA apps to people in the Helix store, and the full sequence includes more precision.

Researchers turn living cells into biological sensing and computing platforms.

The preferred term is “ribocomputing.” Take a molecule of RNA, the “messenger” chemical that carries instructions from a cell’s DNA to the rest of the cell, and basically rewire it. By hacking the RNA, it’s thus possible to take command of the processes of the cell, particularly that of protein synthesis. It’s also possible to rewire the RNA to respond to specific stimuli, offering an engineered microbiological system that reacts to inputs in the same way that an embedded computer might respond to a temperature sensor of accelerometer.

Synthetic biology or “hacked” biology is a quickly growing field, but the term ribocomputing is scarce, mostly limited to a single 2016 study. That was the case at least until this week and the publication of a paper in Nature describing RNA-based synthetic biological circuits that are capable of implementing just what I described above: sensing external signals and directing cellular machinery to respond to those signals in programmed ways. It’s fascinating but also a bit spooky.

Imagine a scientist experimenting on her own genes from her kitchen, rather than going to a physician, because she wants to cure a medical ailment. Another “do-it-yourself” scientist across the country extracts DNA samples from plants to figure out how they affect its growth.

DIY biohacking is a relatively new phenomenon in which scientists (typically those with an interest in genetic engineering) want to take biology experimentation outside of the lab or classroom. Currently, it’s mostly used for medical purposes, but the future of DIY biohacking could look a lot different. So we asked four experts a simple question: By the year 2040, what will be the gene most edited via DIY biohacking?

Research finds that films made up of DNA block dangerous UV rays.

Welcome to Mr Futurist’s first weekly podcast where I discuss what going on in emerging science and technology. Scientists have successfully edited the first human embryo in the U.S. using CRISPR. CRISPR is a gene editing technique that can modify any region of the genome of any species with high precision accuracy. Modifying a species to have certain characteristics or traits. If you’re curious as to what CRISPR is, I have added a link below to an excellent video from Futurist that explains what CRISPR is and what it can be used for, all in 60 seconds. It’s worth a minute of your time.

Cancer continues to be one of the major diseases that plagues humanity. Around the world, approximately 1 in 6 deaths is due to cancer, according to the World Health Organisation (WHO).

The prevalence of cancer is due, in part, to the absence of a universal cure for all forms of the disease. While various treatments are available, each type of cancer generally requires specific treatment.

A new method developed by doctors at the Great Ormond Street Hospital in London presents a hopeful solution. The team has successfully tested their method on two infants with an aggressive form of leukaemia.
