Tardigrades — known affectionately as water bears or moss piglets — have pretty much got it all. These microscopic invertebrates are capable of surviving the most extreme conditions you could dream up, including prolonged desiccation and near-100 percent water loss, freezing and boiling temperatures, intense ionising radiation, and the vacuum of outer space.

Scientists have discovered that to survive extreme desiccation, tardigardes produce a special type of ‘bioglass’ to hold essential proteins and molecules together until they’re rehydrated back to life. Now they’re figuring out how to use this mechanism to develop drought-resistant crops and longer-lasting vaccines.

Back in September, researchers from the University of Chicago announced that they’d discovered a new type of glass — one produced internally by the tardigrade during desiccation. While they’re yet to figure out exactly how the glass is formed, they concluded that it’s produced as a protective mechanism to ensure that tardigrades can survive losing pretty much all of the water in their cells.

If you haven’t heard of the bionic pancreas, it’s likely you soon will. With diabetes on the rise and the demand for insulin therapies becoming a real pain point for the medical establishment, the need for innovative solutions has spiked. Back in April, we reported on the Do-It-Yourself Pancreas system, a closed-loop artificial pancreas scavenged from a Medtronic pump, Dexcom CGM, a Raspberry Pi, and CareLink USB. Now a fully bionic pancreas similar in design to the Do-It-Yourself model is being developed by doctors at Massachusetts General Hospital and Boston University, with the goal of winning FDA approval. If it succeeds, this will likely be the first bionic organ to see widespread adoption.

Let’s examine some of the previous attempts at bionic organs to see if we can catch a glimpse of where things are heading and some of the societal repercussions that lay in wait. The holy grail of bionic organs is without question the human heart. Coronary artery disease being one of the principal causes of the death worldwide, a fully functioning bionic heart could radically change life expectancy and alter the demographic landscape.

The first bionic hearts, designed over 70 years ago, were plagued by problems that often resulted in thromboembolism and hemorrhage, and made this even more of a gamble than donor transplants. Recent technological advances, however — specifically the advent of bio-prosthetic materials that fool the human immune system into believing the bionic heart is an organic part of the body — could indicate a new era of artificial organs is upon us.

Catching sunlight at every angle.

One of the limitations of current solar panel technology is the panels need to be facing in a certain direction to make the most of the Sun’s rays, otherwise the amount of energy they can absorb drops off dramatically. A newly invented material could make the direction of solar panels much less of a concern in the future.

The material has been produced by electrical engineers at the King Abdullah University of Science & Technology (KAUST) in Saudi Arabia and Taiwan’s National Central University. Not only does the glass coating they’ve come up with soak up sunlight from multiple angles more effectively, it’s also able to keep itself clean — the newly treated panels were able to maintain 98.8 percent of their efficiency after six weeks outdoors.

‘In a surprisingly polemic report, ITIF think-tank president Robert Atkinson misinterprets this growing altruistic focus of AI researchers as innovation-stifling “Luddite-induced paranoia.”’

The report released by the ITIF think tank suffers from many problems. It accuses Elon Musk in risking research in the “cars that Google and TESLA are testing”, missing entirely the irony. IMHO, the nomination is not the product of research in what Nick Bostrom, Stephen Hawking, Bill Gates, & Elon Musk actually say.

Each year, the ITIF produces a list of 10 groups they think are holding back technological progress with their annual Luddite award. This year, they included researchers who support AI safety research and autonomous weapons bans, and they called out Elon Musk, Bill Gates and Stephen Hawking by name. The ITIF doesn’t seem to see the irony of calling Elon Musk a luddite despite just landing a rocket, launching auto-piloted electric cars and investing in a $1Bn AI-startup. Read the response written by Stuart Russell and Max Tegmark:

For decades now we’ve been teased with hoverboard concepts, either from science fiction or highly limited real-life versions, but now aerospace company Arca is taking orders for what it claims is the real deal. The ArcaBoard appears to be the closest thing to the technology from Back to the Future: Part II that we’ve seen so far.

The dream of melding biological and man-made machinery is now a little more real with the announcement that Columbia Engineering researchers have successfully harnessed a chemical energy-producing biological process to power a solid state CMOS integrated circuit.

According to study lead professor Ken Shepard, this is the world’s first successful effort to isolate a biological process and use it to power an integrated circuit, much like the ones we use in phones and computers.

The researchers developed the system by using an artificially created lipid bilayer membrane containing naturally occurring ion pumps, which are powered by the biological world’s “energy currency molecule,” ATP (adenosine triphosphate). ATP is the coenzyme that transfers chemical energy between living cells. It is an end product of processes such as photosynthesis and cellular respiration, and it powers the mechanical work of living systems such as cell division and muscle contraction.

Hydras, simple fresh-water animals, have the ability to live forever if kept in ideal conditions, a recent study shows.

The organisms are made mostly of stem cells that have the ability to continually divide, thus constantly renewing the body.

“The differentiated cells of the tentacles and the foot are constantly being pushed off the body and replaced with new cells migrating from the body column,” Daniel Martinez, a biologist at Pomona College, said in a statement.
