View on Nuclear Fusion: a Moment of Truth

Posted by in categories: nuclear energy, physics

Fusion technology promises an inexhaustible supply of clean, safe power. If it all sounds too good to be true, that’s because it is. For decades scientists struggled to recreate a working sun in their laboratories – little surprise perhaps as they were attempting to fuse atomic nuclei in a superheated soup. Commercial fusion remains a dream. Yet in recent years the impossible became merely improbable and then, it felt almost overnight, technically feasible. For the last decade there has been a flurry of interest –and not a little incredulity –about claims, often made by companies backed by billionaires and run by bold physicists, that market-ready fusion reactors were just around the corner.


Until recently the attractions and drawbacks of nuclear fusion reactors were largely theoretical. Within a decade this will not be the case.

Larry Page’s self-flying air taxis to take off in 3 years

Posted by in categories: mobile phones, transportation

Kitty Hawk, an aeronautics firm funded by Alphabet CEO and Google co-founder Larry Page, is inching closer to its plans of creating Uber for flights: it’s unveiled Cora, a fully electric self-flying air taxi that can cover 100 km (62 miles) on a single charge – and you’ll soon be able to hail one with your phone.

Cora has been in the works for a while now, and it’s just been cleared to begin tests in New Zealand. The goal is for Kitty Hawk to launch a fleet of its flying taxis within the next three years. You can Click on photo to start video.

Human Skeletal Muscle Aging and Mutagenesis

Posted by in categories: biotech/medical, genetics, life extension

An article I wrote:


Study based upon human skeletal muscle aging, mutagenesis, and the role of #satellite cells

“A more comprehensive understanding of the interplay of stem cell–intrinsic and extrinsic factors will set the stage for improving cell therapies capable of restoring tissue homeostasis and enhancing muscle repair in the aged.

DNA tests can predict intelligence, scientists show for first time

Posted by in categories: biotech/medical, education, genetics, neuroscience

I ntelligence could be measured with a swab of saliva, or drop of blood, after scientists showed for the first time that a person’s IQ can be predicted just by studying their DNA.

In the largest ever study looking at the genetic basis for intelligence, researchers at the University of Edinburgh and Harvard University discovered hundreds of new genes linked to brain power.

Previous studies have suggested that between 50 per cent and 75 per cent of intelligence is inherited, and the rest comes through upbringing, friendship groups and education. That figure was calculated by studying identical twins who share the same DNA, therefore any differences in IQ between them must be non-genetic.

The Pitch-Black Exoplanet WASP-12b

Posted by in category: space

This artist’s impression shows the exoplanet WASP-12b — an alien world as black as fresh asphalt, orbiting a star like our Sun. Scientists were able to measure its albedo: the amount of light the planet reflects. The results showed that the planet is extremely dark at optical wavelengths.

The Hubble Space Telescope captured two galaxies colliding

Posted by in category: space

Located 350 million light-years away, two neighbor galaxies are slowly being brought together by gravitational forces.

The Hubble Space Telescope captured the pair’s beautiful cosmic dance in a recent photo of the spiral galaxies, known as Arp 256.

One of the most stunning aspects of the image are the swaths of blue on the outer edges of both galaxies. Those are “stellar nurseries,” collections of gas and dust in the process of becoming new stars. Stellar nurseries are set off by intense gravitational forces, like the massive forces of two galaxies slowly merging.

Inevitable muscle wasting of old age could be stopped, scientists believe

Posted by in category: life extension

T he inevitable muscle wasting of old age could be stopped, scientists believe, after discovering why people become frail as they grow older.

Most people become weaker in their later years, as their leg muscles get smaller and less able to bear weight, which often leads to disability and falls.

But until now, nobody has known why the process happens or if it can be reversed.

John Oliver explains Bitcoin, Blockchain & Crypto (with precision & clarity)!

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, internet

John Oliver is a crossover who bridges the art of a comedian with the reporting and perspective of a liberal political pundit. Even detractors acknowledge that Oliver addresses serious issues with unusual wit and humor.

I never thought Oliver could (or would) tackle the topic of cryptocurrency—at least not with value to the viewer. It is too geeky, and too esoteric. (It also cuts into my mission of evangelism and education). smile

He did, and he sparkles! Feel free to jump past the fluff. The Bitcoin tutorial starts at 3:40. Of course, my friend, Shechter, in Long Island New York will bust a gut over what Oliver says at 9:40. It is not only clear and concise, it is accurate and terribly funny!

Whether you are a Bitcoin newbie or a seasoned blockchain coder, this is the video you have been looking for. This one is durable.

Elon Musk plans Mars spaceship, warns there’s a ‘good chance’ that early passengers could die

Posted by in categories: Elon Musk, space travel

Buzz Aldrin, the second man on the Moon, once said, “Mars is there, waiting to be reached.”

If Elon Musk has his way, he’ll be the one to reach it, even if it’s likely to be a dangerous journey that could result in the loss of human life.

Speaking at the South by South West festival in Austin, Texas, SpaceX and Tesla CEO Musk said he envisions test flights of his Mars spacecraft next year, though he cautioned early trips could end in death.

What sets cryptocurrencies apart from each other?

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, internet

Today, I was asked to answer this question at Quora:

What sets each cryptocurrency apart from the others?

“Cryptocurrency” is a broad term. It refers to payment coins, of course—such as Bitcoin and Litecoin. But, because most tradeable tokens attain an asset value, the word is often used to refer to smart contract devices, such as Ethereum, a host of other blockchain based tokens, functional Internet-of-Things tokens, and even ICOs (Initial Coin Offerings). Since people treat ICOs and IOT tokens as investment instruments even if they are useless as a payment mechanism, they all fall within the realm of a cryptocurrency.

So, before addressing the question, let’s distinguish between Altcoins and ICOs. I assume the question refers to Altcoins, and not ICOs…
