So you're planning ahead for your next trip to a remote location, and you try to make sense of those TripAdvisor listings. Great tool - there's a bunch of there around, but let's focus on that one here. It allows you to type in your preferences, location, restrictions, and it dumps a list of facilities together with easy access to the reviews of previous customers. How could we possibly live without it, twenty years ago?
Now, the point of this article is to make sure you can USE the data you are able to get on the web. I use to say "there's not such a thing as too much information", but then I shoud qualify that statement: it all depends on whether you have a brain and a will to put it to work. 

This originated as my answer to a question on the Quora question and answer site: "In what general knowledge domains do alternatives to Wikipedia exist that are significantly superior?". Of course there are examples of much better specialist encyclopedias for various knowledge domains. But you can also do better than Wikipedia using content derived from Wikipedia itself. I think my own new wikis are an example of this, for a simple reason. Because we can fix various errors that can't be fixed there and add new content that can't be added there.

Dr. Jane Goodall is in a panic about GMOs and all of modern agriculture. What isn't plagiarized in her screeds about food is a mishmash of conjecture, anti-science mysticism, and lack of a clue about biology. She is not alone in losing her mind a bit with age. Dr. Linus Pauling became obsessed with Vitamin C as he aged, his claim that high doses would cure a cold is still promoted by supplement salespeople today. Dr.

What is a photon jet? Despite their exotic name, photon jets are a well studied thing nowadays. The original studies were performed by experimentalists who aimed to test quantum chromodynamics: they used to spend their time discriminating prompt photon production in hadron collisions from backgrounds. I remember a lot of such studies were performed in the 80ies and 90ies by my CDF colleagues, especially within the "QCD working group".
The importance of the detection of single, isolated photons of high energy has risen enormously since then, given their role in the discovery of the Higgs boson. Photon jets are in fact the background to beat down if you want a neat peak of H --> γγ decays to pop out of a mass histogram constructed from events featuring two photon candidates.

The transition from ape-like shuffling to upright walking (bipedalism) as we do has long fascinated scientists. Why did it happen? When? 

The second question is a little closer to being solved. An analysis of 3.6 million year old hominin footprints in Tanzania suggests our ancestors evolved the hallmark trait of extended leg, human-like bipedalism substantially earlier than previously thought. Many millions of years before humans. Like the chicken and the egg, there is a clear science answer about which came first even if philosophers are baffled.

Researchers at Carnege-Mellon University have found a way to use Artificial Intelligence (AI) schemes to transfer content from one video to the style of another. So they can make a daffodil bloom like the way a hibiscus bloom does or make clouds that are crossing the sky rapidly on a windy day be slowed to give the appearance of calmer weather during movie shoots.

There is a vicious cycle of vanity on social media, according to new results. College-age women who viewed positive feedback on Instagram selfies then experienced greater body dissatisfaction - because they put more focus on appearance and in the end fueled body dissatisfaction among viewers.

A new photoelectrode can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods, another step on the road to turning solar power from an expensive subsidized sideshow into the default energy of the future.

Once upon a time we all knew what censorship was, who the good and bad guys were, and what could be done to make the world a better place. Look up the noun “censor” in the Oxford English Dictionary and you’ll find an outline of a much-told story under definition 2 (b):

“An official in some countries whose duty it is to inspect all books, journals, dramatic pieces, etc, before publication, to secure that they shall contain nothing immoral, heretical, or offensive to the government.”

Attributing the first instance of this usage to the English poet John Milton, the lexicographers illustrated it with a quotation from his anti-censorship pamphlet, Areopagitica (1644):

The famous paradox 'which came first, the chicken or the egg?' was created by philosophers to discuss cause and effect. Since chickens lay eggs, and eggs produce chickens...you get the idea.
