First hint of how DNA calculators could supercharge computing

Posted by in categories: biotech/medical, computing, quantum physics

By Matt Reynolds

By making DNA endlessly change, researchers have shown how a biological computer might one day solve problems much faster than conventional computers or even quantum computers. It’s still a long way from being functional though.

The DNA-based system is an experiment in how it may be possible to make a theoretical type of computer known as a non-deterministic universal Turing machine.

From AI to Anxiety Relief, The Brain Needs a Body

Posted by in categories: biotech/medical, information science, life extension, robotics/AI

The goal of transcending flesh is an old fetish. Yogis meditated and fasted for eons in order to rise above our ‘meat casing,’ performing painful ablutions and inventing kriyas, intense breathing exercises that are physiologically indistinct from intentional hyperventilation. The goal of many religions, from some forms of Tibetan Buddhism to numerous strains of Christianity and Islam, is all about letting the spirit soar free.

While language changes, pretensions remain. Today we talk about ‘uploading consciousness’ to an as of yet discovered virtual cloud. Artificial intelligence is only moments away, so the story goes, with experts weighing in on the ethical consequences of creating machines void of emotional response systems. In this view consciousness, itself a loaded and mismanaged term, is nothing more than an algorithm waiting to be deciphered. Upon cracking the code, immortality awaits.

Of course others are more grounded. The goal of extending life to 150 years includes the body by default, though the mind is still championed above all else. Yet we seem to age in opposing directions by design. At forty-one little has changed in how I think about myself, yet my body is decaying: a post-knee surgery creek here, a perpetual tight shoulder there. It certainly feels like a slowly approaching transition, even if that, like much of life, is an illusion.

Can math help explain our bodies—and our diseases?

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

What makes a cluster of cells become a liver, or a muscle? How do our genes give rise to proteins, proteins to cells, and cells to tissues and organs?

The incredible complexity of how these biological systems interact boggles the mind—and drives the work of biomedical scientists around the world.

But a pair of mathematicians has introduced a new way of thinking about these concepts that may help set the stage for better understanding of our bodies and other living things.

Nanoengineers 3D print biomimetic blood vessel networks

Posted by in categories: 3D printing, bioengineering, bioprinting, biotech/medical

The new research, led by nanoengineering professor Shaochen Chen, addresses one of the biggest challenges in tissue engineering: creating lifelike tissues and organs with functioning vasculature — networks of blood vessels that can transport blood, nutrients, waste and other biological materials — and do so safely when implanted inside the body.

Researchers from other labs have used different 3D printing technologies to create artificial blood vessels. But existing technologies are slow, costly and mainly produce simple structures, such as a single blood vessel — a tube, basically. These blood vessels also are not capable of integrating with the body’s own vascular system.

“Almost all tissues and organs need blood vessels to survive and work properly. This is a big bottleneck in making organ transplants, which are in high demand but in short supply,” said Chen, who leads the Nanobiomaterials, Bioprinting, and Tissue Engineering Lab at UC San Diego. “3D bioprinting organs can help bridge this gap, and our lab has taken a big step toward that goal.”

Hard drives of the future could be made of DNA

Posted by in categories: biotech/medical, computing, internet, mathematics

Our data-driven society is churning out more information than traditional storage technology can handle, so scientists are looking for a solution in Nature’s hard drive: DNA. A pair of researchers at Columbia University and the New York Genome Center recently wrote a full computer operating system, an 1895 French film, an Amazon gift card and other files into DNA strands and retrieved them without errors, according to a study published in the latest edition of Science.

There are several advantages to using DNA. It’s a lot smaller than traditional media; a single gram can fit 215,000 times more data than a one terabyte hard drive, The Atlantic notes. It’s also incredibly durable. Scientists are using DNA thousands of years old to de-extinct wooly mammoths, for example. But, until now, they’ve only unlocked a fraction of its storage capacity. Study coauthors Yaniv Erlich and Dina Zielinski were able to fit the theoretical maximum amount of information per nucleotide using a new method inspired by how movies stream across the internet.

“We mapped the bits of the files to DNA nucleotides. Then, we synthesized these nucleotides and stored the molecules in a test-tube,” Erlich explained in an interview with ResearchGate. “To retrieve the information, we sequenced the molecules. This is the basic process. To pack the information, we devised a strategy—called DNA Fountain—that uses mathematical concepts from coding theory. It was this strategy that allowed us to achieve optimal packing, which was the most challenging aspect of the study.”

IBM launches IBM Q initiative to create 50+ qubit universal quantum computer

Posted by in categories: biotech/medical, business, chemistry, quantum physics, robotics/AI

IBM Q is an industry-first initiative to build a commercially available universal quantum computers for business and science. While technologies like AI can find patterns buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be seen and the number of possibilities that you need to explore to get to the answer are too enormous ever to be processed by classical computers.

IBM Q quantum systems and services will be delivered via the IBM Cloud platform and will be designed to tackle problems that are too complex and exponential in nature for classical computing systems to handle. One of the first and most promising applications for quantum computing will be in the area of chemistry and could lead to the discovery of new medicines and materials. IBM aims at constructing commercial IBM Q systems with ~50 qubits in the next few years to demonstrate capabilities beyond today’s classical systems, and plans to collaborate with key industry partners to develop applications that exploit the quantum speedup of the systems.
