Neanderthal Sculpture Garden

A mysterious series of rock formations recently discovered in France have been identified as potentially religious or cultural work of Neanderthals from over 175,000 years ago, over four times older than the oldest cave paintings. Inside Bruniquel Cave in southwest France, researchers have found formations of broken stalagmites that appear to have been arranged intentionally, and are scorched in places with fire. These findings suggest that Neanderthals were not the brainless brutes we think of them as, but similar to us in their capacity for culture.

The study, led by Belgium-based scientist Sophie Verheyden, cites, “The regular geometry of the stalagmite circles, the arrangement of broken stalagmites, and several traces of fire,” as well as their location over 1,000′ into the cave to suggest mastery of the environment, “which can be considered a major step in human modernity.” Uranium dating (more accurate than carbon dating) indicates that these rock circles were made 176,600 years ago makes this feat very impressive. We know that Neanderthals could make markings resembling abstract art and use fire, but they’re not known for exploring caves past the reach of sunlight, much less to create works that could be a prehistoric sculpture garden.

Another day, another screed. This one certainly gave me a good laugh, as it seems I now have a religion. I guess we SJWs are upsetting everyone these days. Tsk. Be sure to put your melodrama meters away, critical levels here, of the “I’m a libertarian, of course I’m right!” kind.

NEW YORK — There’s a new religion exploding on the campuses of American universities and colleges, says Thomas Cooley professor of ethical leadership at New York University, Jonathan Haidt. And if it isn’t stopped, it might just be better to shut them all down in the next 10 or 20 years.

The religion of fundamental social justice sweeping across college campuses is so alarming, intense, and dripping with such extreme liberal fundamentalism, says Haidt, it has created an existential crisis for American academia while punishing heretics with public shame.

“There is an extremely intense, fundamental social justice religion that’s taking over, not all students, but a very strong [space] of it, at all our colleges and universities. They are prosecuting blasphemy and this is where we are,” Haidt warned an audience about the religion at a lecture billed “The American University’s New Assault on Free Speech,” organized by the Manhattan Institute in New York City this week.

[…]

When social issues like racism or sexism are treated as sacred, he says, it becomes difficult to have honest conversations about them.

“So if that’s the basic psychology and as religion itself has been retreating and kids are raised in a more secular environment, then what takes the place of that? There are lots of sacred spaces. Fighting racism, a very, very good thing to do, but when you come to sacred principles, sacred, this means no tradeoffs,” Haidt said.

“There is no nuance, you cannot trade off any other goods with it. So if you organize around fighting racism, fighting homophobia, fighting sexism, again all good things, but when they become sacred, when they become essentially objects of worship, fundamentalist religion, then when someone comes to class, someone comes to your campus, and they say the rape culture is exaggerated, they have committed blasphemy,” he said.

This religion of fundamental social justice is so frightening, even liberals are worried about it. But they aren’t speaking up, says Haidt, who describes himself as a libertarian.

“The great majority of people are really alarmed by what’s happening. There is a small group on campus of illiberal people. The illiberal left against the liberal left. The liberal left is uncomfortable but has so far been silent,” Haidt said. It is this illiberalism on campus that has given rise to groups such as Black Lives Matter where “nobody can say no to them.”

[…]

Haidt, however, doesn’t think life will continue down this road for American academia pointing to a growing counterculture movement involving projects such as the Heterodox Academy. […] So we are doing all these projects to use market forces to swamp the illiberals and basically take advantage of people’s disgust with the current situation.”

Mathematically Correct Breakfast

Also known as Möbius strip bagel. More room for cream cheese!

The real question is: is it worth it? How much more spreading room do you actually get? Mathematician Antonio R. Vargas has done the calculations, and they get quite complex, veering into calculus. On a webpage hosted by Dalhousie University, Vargas concludes that “the ratio of the surface area exposed by cutting along the two-twist Möbius strip to the area exposed by cutting the bagel straight in half is approximately: 1 + 1/6 (heights/width-height)2.”

To make a long story short, the amount of spreading surface you get depends on the size of your bagel, but it will always be more than if you had cut it in half.

rocks-1

Jller is part of an ongoing research project in the fields of industrial automation and historical geology. It is an apparatus, that sorts pebbles from a specific river by their geologic age. The stones were taken from the stream bed of the German river Jller, shortly before it merges with the Danube, close to the city of Ulm. The machine and its performance is the first manifestation of this research.
A set of pebbles from the Jller are placed on the 2×4 meter platform of the machine, which automatically analyzes the stones in order to then sort them. The sorting process happens in two steps: Intermediate, pre-sorted patterns are formed first, to make space for the final, ordered alignment of stones, defined by type and age. Starting from an arbitrary set of stones, this process renders the inherent history of the river visible.
The history, origin and path from each stone found in a river is specific to the location, as every river has a different composition of rock types.

The neural basis of seeing God?

original

A remarkable case report describes the brain activity in a man at the moment that he underwent a revelatory experience.

According to the authors, Israeli researchers Arzy and Schurr, the man was 46 years old. He was Jewish, but he had never been especially religious. His supernatural experience occured in hospital where he was undergoing tests to help treat his right temporal lobe epilepsy (TLE), a condition which he had suffered from for forty years. As part of the testing procedure, the patient stopped taking his anti-convulsant medication. Here’s how the authors describe what happened:

While lying in bed, the patient abruptly “froze” and stared at the ceiling for several minutes, stating later that he felt that God was approaching him. He then started chanting prayers quietly, looked for his Kippa and put it on his head, chanting the prayers more excessively. Then, abruptly, he yelled “And you are Adonai (name of the Hebrew God) the Lord!”, stating later that god had revealed to him, ordering him to bring redemption to the people of Israel.

The patient then stood up, detached the EEG electrodes from his skin, and went around the department trying to convince people to follow him, stating that “God has sent me to you”. When further questioned, he said that he does not have a concrete plan, but he is sure that God is going to instruct him what he and his followers should do on their way to redemption.

Sir David Attenborough turns 90

_89632421_89632420

Tributes have been paid to renowned naturalist and broadcaster Sir David Attenborough who has turned 90.

CBBC wildlife star Steve Backshall said Sir David “completely transformed my view of the wild world”.

Sir David did that for me too, and much more. Growing up, it was Sir David’s journeys across the world and his science narratives that helped to keep that love of learning alive in me. Thanks aren’t enough. Happiest of birthdays to Sir David, and I hope he’s with us all a long time yet.

The BBC has a special page: Celebrating Attenborough at 90.

95 Million Year Old Octopus, Still Awesome!

Dutch wildlife artist Esther van Hulsen was recently given an assignment unlike her typical drawings of birds and mammals from life—a chance to draw a prehistoric octopus 95 million years after its death. Paleontologist Jørn Hurum supplied Hulsen with ink extracted from a fossil found in Lebanon in 2009, received as a gift from the PalVenn Museum in 2014. After several millennia Hulson was surprised to find that the color had remained so vibrant, preserved all of this time in the cephalopod’s ink sac. “Knowing that this animal has used this ink to survive is absolutely amazing,” said van Hulsen of the prehistoric ink.

Algae-Based Water Bottle Biodegrades When It’s Empty.

Very cool, this. More people need to work on the plastic problem. It seems as much as I try to eliminate plastic products from my life, I end up surrounded anyway.

Plastic bottles can lay around in landfill sites or the ocean for centuries. While our planet struggles to cope with our ever-increasing appetite for plastic, an Icelandic product design student was inspired to create a little something to address the issue.

Ari Jónsson, from the Iceland Academy of the Arts, has harnessed the properties of red algae to create a biodegradable bottle for drinking water. He unveiled his invention at Reykjavik design festival DesignMarch last month. The bottles are made out of agar powder, which derives from the supporting structure in the cell walls of certain species of algae. If this is added to water and allowed to cool, it will eventually set and mould into a jelly-like substance.

The bottle retains its shape when it’s full of fluid but will start to decompose as soon as it’s empty it.
