Universe might contain millions of black holes

[from Engadget]

Black holes are, by definition, impossible to see by conventional methods and are often further obscured by thick blankets of dust or gas. But that’s not an issue for NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR). It can peek through the obscuring layers and monitor the black holes via the high-energy X-rays that they emit. And, after a recent survey that spotted five previously unknown supermassive black holes in the centers of various galaxies, NASA researchers now think there could be millions of of them dotting the Universe like the holes of an intergalactic colander.

“Thanks to NuSTAR, for the first time, we have been able to clearly identify these hidden monsters that are predicted to be there, but have previously been elusive because of their surrounding cocoons of material,” said George Lansbury of Durham University in a statement. “Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole universe, then the predicted numbers are huge and in agreement with what we would expect to see.” The team’s research has been accepted for publication in The Astrophysical Journal.

Evolutionary Biologist Suggests Aliens Look Like Us

According to the reputable Australian astro-enthusiast journal, SkyNews, a leading biologist says that it is surprising we have not already discovered extra-terrestrials that look like us — given the growing number of Earth-like planets now discovered by astronomers.

Simon Conway Morris, an evolutionary biologist suggests that aliens resembling humans must have evolved on other planets. He bases the claim on evidence that different species will independently develop similar features which means that life similar to that on Earth would also develop on equivalent planets.

The theory, known as convergence, says evolution is a predictable process which follows a rigid set of rules. Read the full story at Skynews

The Netherlands: A Look At The World’s High-Tech Startup Capital

Behind London and Berlin, the Dutch startup scene is already considered to be one of the most prominent in Europe. (If it feels unfair to weigh an entire country against individual cities, consider that the Netherlands has 17 million people crammed into an area half the size of South Carolina.)

Construction Project of the Day: Dubai is 3D-Printing an Entire Building

We’ve seen 3D-printed cars and even 3D-printed body organs, but now the city of Dubai plans to use the technology to create an entire office building. Because they are always trying to one-up themselves. Dubai is known around the world for its over-the-top architecture, extreme stunts and attention-grabbing New Year’s Eve light shows.

Major bank admits bitcoin could destroy banks, brokers & exchanges

July 9 update:
3 days after posting, Visa acknowledged that Bitcoin has a future in payments. This is an understatement, of course. The bank described below goes a step further by acknowledging that the entire financial infrastructure may cave to cryptocurrencies.

French bank BNP Paribas warned customers and investors that the technology behind bitcoin might one day overtake conventional, account-based financial institutions, thus rendering existing companies redundant (that’s British for “obsolete”).* It’s a tectonic acknowledgement from one of the world’s biggest banks.

Analyst Johann Palychata writes in the company’s magazine Quintessence that Bitcoin’s blockchain, the underlying architecture that allows cryptocurrency to function, “should be considered as an invention like the steam or combustion engine,” that has the potential to transform the world of finance and beyond.

Check out the full story by Oscar Williams-Grut at Business Insider.

* Although Bitcoin will obsolete the current service mix of financial institutions, it is my opinion that for savvy governments and established businesses, it represents a long term opportunity rather than a threat. —PR

How computers are learning to make human software work more efficiently — John R. Woodward, Justyna Petke And William Langdon | The Conversation

“Genetic improvement involves writing an automated “programmer” who manipulates the source code of a piece of through trial and error with a view to making it work more efficiently. This might include swapping lines of code around, deleting lines and inserting new ones – very much like a human programmer. Each manipulation is then tested against some quality measure to determine if the new version of the code is an improvement over the old version. It is about taking large software systems and altering them slightly to achieve better results. Read more
