Unlike Nuclear fusion which has never had net generation of power, molten salt nuclear fission power had 2.5 megawatts of net power generation from a US nuclear prototype back in the 1960s. The US government had major work on molten salt nuclear reactors form the 1950s through the 1970s.
There is now a multi-billion race from many US companies and China and Canada and European countries to develop molten salt nuclear power.
A sapphire-colored dye called methylene blue is a common ingredient in wastewater from textile mills.
But University at Buffalo scientists think it may be possible to give this industrial pollutant a second life. In a new study, they show that the dye, when dissolved in water, is good at storing and releasing energy on cue.
This makes the compound a promising candidate material for redox flow batteries—large, rechargeable liquid-based batteries that could enable future wind farms and solar homes to stockpile electricity for calm or rainy days.
Researchers have demonstrated that telomerase gene therapy does not increase the risk of cancer, even in strains of mice that are particularly susceptible to cancer [1].
A tale of telomeres
Short telomeres trigger cellular senescence and are thought to be one of the primary hallmarks of aging, which has led to various researchers seeking ways to restore the telomeres in order to prevent cells from dying and to encourage division and tissue regeneration. We won’t go over the basics of telomeres and how they influence aging here, but if you would like to learn more, check out our telomeres article, which explains it all.
Elysium Health has released a new supplement called Basis which can help keep your body healthy as you age. According to a double-blind, placebo controlled study, the supplement increases your body’s levels of NAD+, which support important activities within our cells and contributes to our health.
Tesla’s Semi truck has already made some city-to-city trips, but how does it fare on cross-country jaunts — you know, what it’ll be doing when it enters service? Just fine, if you ask Elon Musk. In response to an Electrek piece on the Semi’s latest visit (to Arkansas trucking behemoth J.B. Hunt), the CEO noted that the Semi has been traveling thousands of miles entirely by itself, using the existing Supercharger network. The only necessary help is an “extension cord” to help the truck plug in. To be exact, it’s a system of cords that plugs into multiple stations at once to top up the Semi’s giant battery before the company’s Megachargers come online.
That solo travel is likely meant in part to reassure customers (including J.B. Hunt) that the Semi is already capable of handling long-distance trips without escorts. However, it does leave a few open questions. How long does it take to top up using Superchargers, and how likely is it that drivers could rely on them when Megachargers aren’t available? While it’s easy for a Tesla-operated truck to cross the US using the existing framework, it’d be another matter with thousands of third-party trucks in service. This is a significant step toward the Semi hitting the road in earnest, but there are many more steps to go.
What’s cool is that it was driven across the country alone (no escort or any accompanying vehicles), using the existing Tesla Supercharger network and an extension cord— Elon Musk (@elonmusk) August 25, 2018

The old boundaries of the human self are being blurred by technology. The risks are real, but the potential is astounding.
Scotrenewables Tidal Power, a Scottish engineering company, is focused on an energy source they call “tidal energy generation.” A video promoting their solution: They have plenty to show for their efforts, namely, the world’s most powerful operational tidal turbine, the SR2000 2MW.
A reduction in manufacturing and installation costs plus simple, quick and low cost maintenance strategies will be key to success.
The company release said, “Scotrenewables Tidal Power has set another record with its first 2MW floating tidal stream turbine with the unit clocking up over 3GWh of renewable electricity in its first year of testing at the European Marine Energy Centre (EMEC) in Orkney, Scotland.”
GENEVA (AP) — Experts from scores of countries are meeting to discuss ways to define and deal with “killer robots” — futuristic weapons systems that could conduct war without human intervention.
The weeklong gathering is the second this year at U.N. offices in Geneva to focus on such lethal autonomous weapons systems and explore ways of possibly regulating them, among other issues.
Some top advocacy groups say governments and militaries should be prevented from developing such systems, which have sparked fears and led some critics to envisage harrowing scenarios about their use.

Philosophers have debated the nature of “nothing” for thousands of years, but what has modern science got to say about it? In an interview with The Conversation, Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, explains that when physicists talk about nothing, they mean empty space (vacuum). This may sound straightforward, but experiments show that empty space isn’t really empty – there’s a mysterious energy latent in it which can tell us something about the fate of the universe.
Rees was interviewed for The Conversation’s Anthill podcast on Nothing. This Q&A is based on an edited transcript of that interview.
