Well, here's something that won't affect anyone's life in any meaningful way.

Dammit, I've been reading too much politics and missed this sad and statistically significant item

http://www.cbsnews.com/pictures/notable-deaths-in-2017/2/

Quote
Swedish academic, doctor and statistician Hans Rosling (July 27, 1948-February 7, 2017) captured the world’s attention though his original and entertaining presentations of data on such topics as population growth, child mortality, poverty, and misunderstandings about the developing world.

Co-founder of the Gapminder foundation, Rosling called his role that of an “edutainer.” His 2006 TED Talk, titled “The Best Stats You’ve Ever Seen,” has racked up more than 11 million views.
If the answer is Donald J Trump then it must have been a fucking stupid question.

“From rocks in Colorado, evidence of a ‘chaotic solar system’”

The short YouTube clip is particularly interesting.

Deepmind knocks it out the park again. Pretty much the only thing worth talking about in the ML community since AlphaGo, in terms of where it goes next,  has been episodic memory. Lot of labs trying to develop solutions. This is pretty f'kin awesome.

“Humans as Agents in the Termination of the African Humid Period”

A number of popular science websites made passing references to this paper about the formation of the Sahara Desert in the past couple of weeks, but did not include much from the paper itself.

I’m not well read in the field of anthropology, and have no knowledge of Dr. David K. Wright’s reputation, but I found the following paper to be particularly interesting:

http://journal.frontiersin.org/article/10.3389/feart.2017.00004/full

In his Conclusion, Dr. Wright states, “Human-induced landscape pressures are as old as humanity itself. Although there is little doubt that post-Industrial anthropogenic activities have placed more global stress on the environment than for the millions of preceding years, human impacts are not concisely restricted to the post-Industrial world.”

“Explaining the accelerating expansion of the universe without dark energy”

“In the new work, the researchers, led by Phd student Gábor Rácz of Eötvös Loránd University in Hungary, question the existence of dark energy and suggest an alternative explanation. They argue that conventional models of cosmology (the study of the origin and evolution of the universe), rely on approximations that ignore its structure, and where matter is assumed to have a uniform density.”

They further write:

“In practice, normal and dark matter appear to fill the universe with a foam-like structure, where galaxies are located on the thin walls between bubbles, and are grouped into superclusters. The insides of the bubbles are in contrast almost empty of both kinds of matter.”

Here’s the link to the article: http://www.ras.org.uk/news-and-press/2968-explaining-the-accelerating-expansion-of-the-universe-without-dark-energy

Hardcore students of cosmology can download the complete paper at: https://arxiv.org/abs/1607.08797

This was pretty neat:

Researchers are analyzing DNA from ancient individuals found in southeast Alaska, coastal British Columbia, Washington state and Montana. A new genetic analysis of some of these human remains finds that many of today’s indigenous peoples living in the same regions are descendants of ancient individuals dating to at least 10,300 years ago.

Also, using bacteria to purify water. Ingenious!

A new system that uses bacteria to turn non-potable water into drinking water will be tested next week in West Vancouver prior to being installed in remote communities in Canada and beyond.

‘Research challenges understanding of quantum theory’

“Researchers at the University of East Anglia (UEA) have shown that when photons – the fundamental particles of light – are created in pairs, they can emerge from different, rather than the same, location.”

“The ground-breaking research could have significant implications for quantum physics, the theoretical basis of modern physics. Until now, the general assumption was that such photon pairs necessarily originate from single points in space.”

Here’s the link to the press release: https://www.uea.ac.uk/about/-/light-particles-challenges-understanding-of-quantum-theory

Unfortunately, the press release provides no quantitative data about the distance between the photon pair emergence points. And, the research paper itself appears to be only available for purchase from the journal Physical Review Letters.

“Found: Fresh Clues to Mystery of King Solomon's Mines”

Whether or not one believes in the authenticity of the biblical story, it is significant that people went to such effort to mine and smelt copper, 3,000 years ago, in such an inhospitable place. (And, it’s amazing what archeologist can learn from old animal waste.)
