A cutaway view of the proposed ARC reactor (credit: MIT ARC team)

MIT plans to create a new compact version of a tokamak fusion reactor with the goal of producing practical fusion power, which could offer a nearly inexhaustible energy resource in as little as a decade.

Fusion, the nuclear reaction that powers the sun, involves fusing pairs of hydrogen atoms together to form helium, accompanied by enormous releases of energy.

The new fusion reactor, called ARC, would take advantage of new, commercially available superconductors — rare-earth barium copper oxide (REBCO) superconducting tapes (the dark brown areas in the illustration above) — to produce stronger magnetic field coils, according to Dennis Whyte, a professor of Nuclear Science and Engineering and director of MIT’s Plasma Science and Fusion Center.

We’re not quite in the fusion age yet, but this is promising. For 50 years, researchers have been saying we’re 25 years away from practical fusion. Now they’re saying 5 years.


The small, modular, efficient, less expensive ARC reactor could help to bring the long-sought power source closer to reality.

“We have a few cyborgs on staff. Ben Popper is arguably the reporter best known for peeling back his skin to insert a piece of technology, which he chronicled in his feature, Cyborg America. But others have gone under the knife. I wanted to know why. You know, because I have crippling FOMO.”

What if “life in prison” could mean 100 or 200 or 400 years? Does that change the way that sentences are doled out? What happens when a person gets out of prison?

For all of you who’ve written in asking me to do an episode about longevity, this episode is for you. But instead of looking at the usual living forever stuff, we’re specifically going to talk about what happens when it gets applied to the prison system.

Two-hit model of non-alcoholic fatty liver disease (credit: ILSI Europe)

In an open-access paper in the British Journal of Nutrition, a coalition of 17 experts explain how elevated unresolved chronic inflammation is involved a range of chronic diseases, and how nutrition influences inflammatory processes and helps reduce chronic risk of diseases.

According to the authors, “the nutrition status of the individual with for example a deficiency or excess of certain micronutrients (e.g. folate, vitamin B12, vitamin B6, vitamin 1, vitamin E, zinc) may lead to an ineffective or excessive inflammatory response.

“Studies have showed that high consumption of fat and glucose may induce post-prandial inflammation (manifesting itself after the consumption of a meal), which may have consequences for the development of diabetes and cardiovascular diseases. The Western-style diet, rich in fat and simple sugars but often poor in specific micronutrients, is linked to the increased prevalence of diseases with strong immunogical and autoimmune components, including allergies, food allergies, atopic dermatitis and obesity.”

The left-brain hemisphere of a normal mouse shows the normal level and cellular distribution of the Pax6 gene expression in the developing neocortex. The right-brain hemisphere shows a sustained, primate-like Pax6 expression pattern in the neocortex of a double transgenic mouse embryo. These animals have more Pax6-positive progenitor cells and a higher Pax6 expression level in the germinal layer close to the ventricle in the right hemisphere.

Researchers at the Max Planck Institute of Molecular Cell Biology and Genetics have created a transgenic mouse in which a gene called Pax6, during embryonic development, is highly expressed in a specific group of brain cortical cells called neural progenitor stem cells (the cells that generate all cells that make up the brain).

The resulting mouse brain generated more neurons than normal and exhibited primate-like features — notably those in the top layer, a characteristic feature of an expanded neocortex.

Mouse basal progenitors, in contrast to human, do not express Pax6. In humans, basal progenitors can undergo multiple rounds of cell division, thereby substantially increasing neuron number and ultimately the size of the neocortex.

A reminder: HUMANS premieres in the U.S. Sunday June 28, 2015 at 9PM EDT on AMC.

This eight-part drama series takes place in a parallel present, featuring the Synth — a highly developed, artificially intelligent android servant.

Having seen the first two episodes, I’m totally hooked. I found the show surprisingly believable. It (almost) fills the void left after Almost Human and Fringe.

The Atlantic nailed it in a review: “With its small-bore, domestic focus, Humans has the potential to stand out in the supersaturated genre of A.I. fiction.”
