Investment Strategist Jim Mellon Considers the Near Future of Longevity Science

Posted by in categories: biotech/medical, computing, life extension, science

Interest in rejuvenation biotechnology is growing in the investment quarter.

Mainstream interest in rejuvenation biotechnology is growing.

“Investment in the development of rejuvenation therapies represents an enormous opportunity for profit; these are products for which every adult human being much over the age of 30 is a potential customer at some price point. That is larger than near every existing industry, either within or outside the field of medicine, even given that customers will only purchase such a therapy once every few years, for clearance of metabolic waste, or even just once, for treatments like the SENS approach of allotopic expression of mitochondrial genes. Among the first successful companies in this space, some will grow to become among the largest in the world: I’d wager that the Ford or Microsoft of rejuvenation will be a lot larger than the actual Ford of automobiles or Microsoft of personal computing.”

Nanofabrication Enables “Particle-Accelerator-on-a-Chip” Technology

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

The key to this all working is the design of the nanostructures. If you just have a laser in free space, the particle will just oscillate back and forth, pushing it one way and then the other. It won’t ever gain in total energy. So you need some kind of structure that channels or modulates the fields in such a way that the particle will travel along mainly the peaks of the electromagnetic wave and not into the troughs so that it gets kicks but not deceleration.

In all of the experiments done so far, England explains that the particles are basically filling the whole wave, occupying and seeing both the peaks and troughs. This results in some particles being accelerated while others get decelerated.

“In the future, as one of the next experimental steps what we want is to bunch the particles to make very short little packets of particles that are spaced at exactly the right distance between the peaks so that they will ride only on the peaks,” says England. “So you can think of it as like… ocean waves, and you want your surfers to be positioned only on the peaks of the waves and not in the troughs.”

Tiny fibers open new windows into the brain

Posted by in categories: computing, engineering, neuroscience

For the first time ever, a single flexible fiber no bigger than a human hair has successfully delivered a combination of optical, electrical, and chemical signals back and forth into the brain, putting into practice an idea first proposed two years ago. With some tweaking to further improve its biocompatibility, the new approach could provide a dramatically improved way to learn about the functions and interconnections of different brain regions.

The new fibers were developed through a collaboration among material scientists, chemists, biologists, and other specialists. The results are reported in the journal Nature Neuroscience, in a paper by Seongjun Park, an MIT graduate student; Polina Anikeeva, the Class of 1942 Career Development Professor in the Department of Materials Science and Engineering; Yoel Fink, a professor in the departments of Materials Science and Engineering, and Electrical Engineering and Computer Science; Gloria Choi, the Samuel A. Goldblith Career Development Professor in the Department of Brain and Cognitive Sciences, and 10 others at MIT and elsewhere.

The fibers are designed to mimic the softness and flexibility of brain tissue. This could make it possible to leave implants in place and have them retain their functions over much longer periods than is currently possible with typical stiff, metallic fibers, thus enabling much more extensive data collection. For example, in tests with lab mice, the researchers were able to inject viral vectors that carried genes called opsins, which sensitize neurons to light, through one of two fluid channels in the fiber. They waited for the opsins to take effect, then sent a pulse of light through the optical waveguide in the center, and recorded the resulting neuronal activity, using six electrodes to pinpoint specific reactions. All of this was done through a single flexible fiber just 200 micrometers across — comparable to the width of a human hair.

Elon Musk enters the world of brain-computer interfaces

Posted by in categories: computing, Elon Musk, habitats, neuroscience

EVER since ENIAC, the first computer that could be operated by a single person, began flashing its ring counters in 1946, human beings and calculating machines have been on a steady march towards tighter integration. Computers entered homes in the 1980s, then migrated onto laps, into pockets and around wrists. In the laboratory, computation has found its way onto molars and into eyeballs. The logical conclusion of all this is that computers will, one day, enter the brain.

This, at least, is the bet behind a company called Neuralink, just started by Elon Musk, a serial technological entrepreneur. Information about Neuralink is sparse, but trademark filings state that it will make invasive devices for treating or diagnosing neurological ailments. Mr Musk clearly has bigger plans, though. He has often tweeted cryptic messages referring to “neural lace”, a science-fictional concept invented by Iain M. Banks, a novelist, that is, in essence, a machine interface woven into the brain.

Neuroscientists Have Accidentally Discovered a Whole New Role for the Cerebellum

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

One of the best-known regions of the brain, the cerebellum accounts for just 10 percent of the organ’s total volume, but contains more than 50 percent of its neurons.

Despite all that processing power, it’s been assumed that the cerebellum functions largely outside the realm of conscious awareness, instead coordinating physical activities like standing and breathing. But now neuroscientists have discovered that it plays an important role in the reward response — one of the main drives that motivate and shape human behaviour.

Not only does this open up new research possibilities for the little region that has for centuries been primarily linked motor skills and sensory input, but it suggests that the neurons that make up much of the cerebellum — called granule cells — are functioning in ways we never anticipated.

System allocates data center bandwidth more fairly, so no part of a webpage lags behind others

Posted by in categories: computing, habitats

A webpage today is often the sum of many different components. A user’s home page on a social-networking site, for instance, might display the latest posts from the users’ friends; the associated images, links, and comments; notifications of pending messages and comments on the user’s own posts; a list of events; a list of topics currently driving online discussions; a list of games, some of which are flagged to indicate that it’s the user’s turn; and of course the all-important ads, which the site depends on for revenues.

With increasing frequency, each of those components is handled by a different program running on a different server in the website’s data center. That reduces processing time, but it exacerbates another problem: the equitable allocation of network bandwidth among programs.

Many websites aggregate all of a page’s components before shipping them to the user. So if just one program has been allocated too little bandwidth on the data center network, the rest of the page—and the user—could be stuck waiting for its component.
