What if you Send Bitcoin to a Non-Existent Address?

Posted by in categories: bitcoin, cryptocurrencies, economics

I get this question a lot. Today, I answered it at Quora.com. But, here, in the Lifeboat Blog, I have more bandwidth to elaborate.

Question:

What if I make a typo when sending Bitcoin. The recipient address
may be invalid or it may belong to another individual. —But there
is a third possibility. Couldn’t it be a valid address, but without any
wallet that can receive it? I bet the blockchain catches these errors
—Right? Will I always get my money back?

The short answer:Don’t worry, it cannot happen. That won’t happen either. Sure, it’s possible. That’s wrong, and You’re screwed!

Scientists turn skin cells into muscle cells, a potential boon for research

Posted by in categories: bioengineering, biotech/medical, genetics

TUESDAY, Jan. 9, 2018 — In a potential advance for medical research, scientists say they’ve created the first functioning human muscle from skin cells.

The breakthrough could lead to better genetic or cell-based therapies, as well as furthering investigations into the causes and treatment of muscular disorders, the Duke University team said.

“The prospect of studying rare diseases is especially exciting for us,” Nenad Bursac, professor of biomedical engineering, said in a university news release.

Exercise is Currently the Best Way to Slow Down Aging

Posted by in category: life extension

We have all heard that exercise is good for our health. However, it can not only keep you healthy, it can also slow down some aspects of aging. Some researchers even think that it might be possible to use this knowledge to develop new therapies against aging. While waiting for that to happen, we need to exercise in order to slow down the effects of aging.

How important is it to keep fit?

So, how beneficial is exercising? Well, one of the best studies conducted on this subject showed that women will live 5.6 years longer and men 6.2 years longer if they exercise between 1 and 2.5 hours per week[1]. This makes exercise a better lifestyle choice than any other, at least as long as you’re not counting avoiding downright dangerous behavior, such as smoking.

Wind farms paid £1m a week to switch off

Posted by in category: futurism

Here, $$$$, turn that thing off, you’re making too much cheap power.


New figures show £53m was given to the wind industry last year to keep turbines switched off to regulate electricity supplied to National Grid.

Since wind farms first started receiving constraint payments five years ago, more than £100 million has been handed over in compensation for switching off. Photo: PA

How bacteria turbocharged their motors

Posted by in categories: evolution, habitats, nanotechnology

Using detailed 3D images, researchers have shown how bacteria have evolved molecular motors of different powers to optimize their swimming.

The discovery, by a team from Imperial College London, provides insights into evolution at the molecular scale.

Bacteria use molecular motors just tens of nanometres wide to spin a tail (or ‘flagellum’) that pushes them through their habitat. Like human-made motors, the structure of these nanoscale machines determines their power and the bacteria’s swimming ability.
