There are at least four ways to acquire Bitcoin and three ways to store it…

Acquire Bitcoin: You can trade Bitcoin in person, accept it as a vendor, mine it, or buy on an exchange.

Store Bitcoin: You can keep your Bitcoin in an online/cloud service (typically, one that is connected to your exchange account), keep it on your own PC or phone, or even print it out and store it on a piece of paper. Like a physical coin, the piece of paper has value. It can be placed in your lock box or under your mattress.

Let’s look at the market for Bitcoin Wallets (all of these are free), and then we shall talk about Bitcoin exchange services. This includes my personal recommendation for the typical consumer or coin enthusiast…

Ever wish you could explore the far side of the Moon? Charles Bombardier’s latest concept vehicle would allow you to do just that.

The Breakthrough Starshot is an effort backed by US$100 million from Russian investor Yuri Milner to vastly accelerate research and development of an interstellar space probe.

Leaders of the mission plan to start funding technology-development projects within months, with the aim of launching a fleet of tiny, laser-propelled probes in the next 20 years. The effort would ultimately cost about $10 billion, leaders hope, and take another 20 years to reach Alpha Centauri.

The first truly challenging step in any mission such as Breakthrough Starshot is to accelerate the spacecraft to interstellar velocities.

Japan’s ancient art of paper folding has inspired the design of a potentially trailblazing “smart” radiator that a NASA technologist is now developing to remove or retain heat on small satellites.

Technologist Vivek Dwivedi, who is standing in front of a sputtering reactor used to deposit vanadium-oxide onto sample substrates for testing, is collaborating with Brigham Young University researchers to develop a radiator ideal for small spacecraft.

Lightweight solar sails could bring spacecraft to the nearest star in just 20 years – but hitting the brakes will be challenging. A new paper suggests using the stars themselves to park around their planets.

A group of scientists led by Johannes Fink from the Institute of Science and Technology Austria (IST Austria) reported the first experimental observation of a first-order phase transition in a dissipative quantum system. Phase transitions include such phenomena as the freezing of water at the critical temperature of 0 degrees Celsius. However, phase transitions also occur at the quantum mechanical level, where they are still relatively unexplored by researchers.

One example of a phase transition at the quantum level is the photon-blockade breakdown, which was only discovered two years ago. During photon blockade, a photon fills a cavity in an optical system and prevents other photons from entering the same cavity until it leaves, hence blocking the flow of photons. But if the photon flux increases to a critical level, a quantum phase transition is predicted: The photon blockade breaks down, and the state of the system changes from opaque to transparent. This specific phase transition has now been experimentally observed by researchers who, for the first time, met the very specific conditions necessary to study this effect.

During a phase transition, the continuous tuning of an external parameter, for example temperature, leads to a transition between two robust steady states with different attributes. First-order phase transitions are characterized by a coexistence of the two stable phases when the control parameter is within a certain range close to the critical value. The two phases form a mixed phase in which some parts have completed the transition and others have not, as in a glass containing ice water. The experimental results that Fink and his collaborators will publish in the journal Physical Review X give insight into the quantum mechanical basis of this effect in a microscopic, zero-dimensional system.

A year on and we catch up with two kids who were genetically engineered to treat their cancer. This is the future of medicine.

By Michael Le Page.

Two children treated with gene-edited cells to kill their cancers are both doing well more than a year later. The baby girls were both given the experimental treatment only as a last resort, but clinical trials of the therapy are now getting underway in children and adults in the UK.

Oh, the logic of objections against rejuvenation! bigsmile

If you’ve ever tried to advocate for rejuvenation, you know it is hard. Usually, people deem the idea as crazy/impossible/dangerous well before you get to finish your first sentence. Living too long would be boring, it would cause overpopulation, ‘immortal’ dictators, and what you have. However, you’ve probably never heard anyone use the same arguments to say that we should not cure individual age-related diseases. This is largely because people have little to no idea about what ageing really is, and how it cannot be untangled from the so-called age-related pathologies. These are nothing more, nothing less, than the result of the life-long accumulation of several types of damage caused by the body’s normal operations. Unlike infectious diseases, the diseases of old age are not the result of a pathogen attack, but essentially of your own body falling apart. As I was saying, people are largely unaware of this fact, and therefore expect that the diseases of ageing could be cured one by one without having to interfere with the ageing process itself, as if the two weren’t related at all. The result of this false expectation would be that you could cure Alzheimer’s, Parkinson’s, etc., but somehow old people would still drop dead around the age of 80 just because they’re old. That’s like saying they died of being healthy.

Back to reality, this can’t be done. To cure the diseases of old age, you need to cure ageing itself. If, for whatever reason, you think that curing ageing as a whole would be a bad idea and it should not be done, the only option is to not cure at least some of the root causes of ageing. Consequently, some age-related pathologies would remain as untreatable as they are today.

Now, the typical objections raised against rejuvenation tend to sound reasonable at first. To some, the statement ‘We should not cure ageing because it would lead to overpopulation’ sounds self-evident. However, if we consider the implications of this statement, things start getting crazy. As said, not curing ageing implies not curing some of its root causes, which in turn implies not curing some age-related diseases. Therefore, the sentence ‘We should not cure ageing’ implies ‘We should not cure [insert age-related disease here] ‘. What happens when we reformulate typical objections to rejuvenation in this fashion?
