How The Power Of Synthetic Biology could reshape the world

Posted by in categories: bioengineering, biotech/medical, computing, environmental

Mushroom buildings, jurassic park and terraforming.

Did you ever hear about synthetic biology? No? Imagine that we could alter and produce DNA from scratch just like an engineer. Doesn’t it sound like one of the greatest interdisciplinary achievements in recent history?

Think about it, a bio-technologist is doing more or less the work of a programmer but instead of using a computer language he’s doing it by arranging molecules embedded in every living cell. The outcome, if ever mastered, could reshape the world around us dramatically.

Capacitively coupled arrays of multiplexed flexible silicon transistors for long-term cardiac electrophysiology

Posted by in categories: biotech/medical, computing

Advanced capabilities in electrical recording are essential for the treatment of heart-rhythm diseases. The most advanced technologies use flexible integrated electronics; however, the penetration of biological fluids into the underlying electronics and any ensuing electrochemical reactions pose significant safety risks. Here, we show that an ultrathin, leakage-free, biocompatible dielectric layer can completely seal an underlying array of flexible electronics while allowing for electrophysiological measurements through capacitive coupling between tissue and the electronics, without the need for direct metal contact. The resulting current-leakage levels and operational lifetimes are, respectively, four orders of magnitude smaller and between two and three orders of magnitude longer than those of other flexible-electronics technologies. Systematic electro­physiological studies with normal, paced and arrhythmic conditions in Langendorff hearts highlight the capabilities of the capacitive-coupling approach. These advances provide realistic pathways towards the broad applicability of biocompatible, flexible electronic implants.

Elon Musk Launches Neuralink to Connect Brains With Computers

Posted by in categories: biotech/medical, computing, Elon Musk, neuroscience

Somewhere in his packed schedule, he has found time to start a neuroscience company that plans to develop cranial computers, most likely to treat intractable brain diseases first, but later to help humanity avoid subjugation at the hands of intelligent machines.

Elon Musk’s new co could allow uploading, downloading thoughts: Wall Street Journal

Posted by in categories: biotech/medical, computing, Elon Musk, neuroscience, singularity

This is big: Is the Singularity a step closer?

Tesla Inc founder and Chief Executive Elon Musk has launched a company called Neuralink Corp through which computers could merge with human brains, the Wall Street Journal reported, citing people familiar with the matter.

Neuralink is pursuing what Musk calls the “neural lace” technology, implanting tiny brain electrodes that may one day upload and download thoughts, the Journal reported. (on.wsj.com/2naUATf)

Scientists find a low-cost way to build genomes from scratch

Posted by in categories: biotech/medical, computing, genetics

To put it mildly, sequencing and building a genome from scratch isn’t cheap. It’s sometimes affordable for human genomes, but it’s often prohibitively expensive (hundreds of thousands of dollars) whenever you’re charting new territory — say, a specific person or an unfamiliar species. A chromosome can have hundreds of millions of genetic base pairs, after all. Scientists may have a way to make it affordable across the board, however. They’ve developed a new method, 3D genome assembly, that can sequence and build genomes from the ground up for less than $10,000.

Where earlier approaches saw researchers using computers to stick small pieces of genetic code together, the new technique takes advantages of folding maps (which show how a 6.5ft long genome can cram into a cell’s nucleus) to quickly build out a sequence. As you only need short reads of DNA to make this happen, the cost is much lower. You also don’t need to know much about your sample organism going in.

As an example of what’s possible, the team completely assembled the three chromosomes for the Aedes aegypti mosquito for the first time. More complex organisms would require more work, of course, but the dramatically lower cost makes that more practical than ever. Provided the approach finds widespread use, it could be incredibly valuable for both biology and medicine.

Breaking the Supermassive Black Hole Speed limit

Posted by in categories: computing, cosmology

A new computer simulation helps explain the existence of puzzling supermassive black holes observed in the early universe. The simulation is based on a computer code used to understand the coupling of radiation and certain materials. “Supermassive black holes have a speed limit that governs how fast and how large they can grow,” said Joseph Smidt of the Theoretical Design Division at Los Alamos National Laboratory, “The relatively recent discovery of supermassive black holes in the early development of the universe raised a fundamental question, how did they get so big so fast?”

Using computer codes developed at Los Alamos for modeling the interaction of matter and radiation related to the Lab’s stockpile stewardship mission, Smidt and colleagues created a simulation of collapsing stars that resulted in supermassive black holes forming in less time than expected, cosmologically speaking, in the first billion years of the universe. “It turns out that while supermassive black holes have a growth speed limit, certain types of massive stars do not,” said Smidt. “We asked, what if we could find a place where stars could grow much faster, perhaps to the size of many thousands of suns; could they form supermassive black holes in less time?” A video about the discovery: https://www.youtube.com/watch?v=LD4xECbHx_I&feature=youtu.be

Europe has a five year project to scale up molecular biocomputers which could outperform quantum computers

Posted by in categories: computing, quantum physics, security

Electronic computers are extremely powerful at performing a high number of operations at very high speeds, sequentially. However, they struggle with combinatorial tasks that can be solved faster if many operations are performed in parallel.

The EU Horizon 2020 has launched Bio4Comp, a five-year €6.1M project to build more powerful and safer biocomputers that could outperform quantum computing.

The Bio4Comp project has the ambitious goal of building a computer with greater processing speed and lower energy consumption than any of the most advanced computers existing today. Ultimately, this could translate into enabling large, error-free security software to be fast enough for practical use, potentially wiping out all current security concerns.
