New form of gold is much golder than normal gold
Posted by Genevieve Klien in category: futurism
Gold never loses its lustre because it is so chemically unreactive, and now microscopic gold crystals have been made that are even less reactive.

Astronomers observe the magnetic field of the remains of supernova 1987A
Posted by Genevieve Klien in categories: cosmology, evolution
For the first time, astronomers have directly observed the magnetism in one of astronomy’s most studied objects: the remains of Supernova 1987A (SN 1987A), a dying star that appeared in our skies over thirty years ago.
In addition to being an impressive observational achievement, the detection provides insight into the early stages of the evolution of supernova remnants and the cosmic magnetism within them.
“The magnetism we’ve detected is around 50,000 times weaker than a fridge magnet,” says Prof. Bryan Gaensler. “And we’ve been able to measure this from a distance of around 1.6 million trillion kilometres.”

Extra PCs laying around? Why not mine Bitcoin?
Posted by Philip Raymond in categories: bitcoin, cryptocurrencies, economics, internet, supercomputing
I get this question a lot. Today, I was asked to write an answer at Quora.com, a Q&A web site at which I am the local cryptocurrency expert. It’s time to address this issue here at Lifeboat.
Question
I have many PCs laying around my home and office.
Some are current models with fast Intel CPUs. Can
I mine Bitcoin to make a little money on the side?
Answer
Other answers focus on the cost of electricity, the number of hashes or teraflops achieved by a computer CPU or the size of the current Bitcoin reward. But, you needn’t dig into any of these details to understand this answer.
You can find the mining software to mine Bitcoin or any other coin on any equipment. Even a phone or wristwatch. But, don’t expect to make money. Mining Bitcoin with an x86 CPU (Core or Pentium equivalent) is never cost effective—not even when Bitcoin was trading at nearly $20,000. A computer with a fast $1500 graphics card will bring you closer to profitability, but not by much.

Kroger will use autonomous vehicles to deliver groceries this fall
Posted by Dan Kummer in categories: drones, robotics/AI
Gradually automating the entire grocery store process. From initial delivery of products to the store/warehouse. To a store that will be optional to go to, but if you do want to go into the store it will be almost fully automated, to delivery drones and self driving vehicles that will bring you your order in under an hour. That is what Amazon is really up to.
Self-driving delivery startup Nuro scores major deal with Kroger.

Scientists can 3D print human heart tissue now. The future is here
Posted by Genevieve Klien in categories: 3D printing, bioprinting, biotech/medical
One day, 3D bioprinting will be used for printing out entire new organs to replace our old, knackered ones. This week, Chicago-based biotech startup Biolife4D announced a milestone on the road to this goal: Its ability to bioprint human cardiac tissue. Here’s why that’s important.
