Chinese researchers demonstrated quantum entanglement at a record distance, between a satellite and ground stations 1,200 kilometers apart. When objects are quantum entangled, their quantum states are linked. Measuring the state of one affects the state of the other. It's weird shit. So weird that Einstein called it "spooky action at a distance."
The experiment by physicists at Shanghai's University of Science and Technology of China could eventually lead to highly-secure communications technologies in space and back on Earth.
"I'm personally convinced that the internet of the future will be based on these quantum principles," says Anton Zeilinger, a physicist at the Austrian Academy of Sciences in Vienna who was not involved in the experiment.

Derek Muller of the YouTube channel Veritasium uses a nifty trick to make visible the invisible air currents, temperature gradients, and differences in air pressure around us. The process is called Schlieren photography and with the right equipment and some precision alignment, you can try it at home. As Muller explains:

I first saw a Schlieren imaging setup around ten years ago in Melbourne. I was immediately fascinated by the way I could see the warm air coming off my hand. I hadn’t expected the currents to be moving that fast or to be so visible. This was a tricky setup to get right because alignment is very important and here I’m just working with what I had lying around the house mostly (plus the mirror). For the best Schlieren photography, making sure the mirror is stable is essential. I want to improve my setup so the mirror doesn't wobble back and forth too much creating the pulsing light and dark sections of this video.
On June 16, 1963, Soviet cosmonaut Valentina Tereshkova became the first woman in space. She orbited the Earth 48 times over a period of three days. Inspired by Yuri Gagarin who in 1961 became the first person in space, Tereshkova applied to the Russian space program and was accepted based on her extensive background as a skydiver. It wasn't until 40 years later that Tereshkova's nearly tragic experience in orbit was made public.
An error in the spacecraft's automatic navigation software caused the ship to move away from Earth. Tereshkova noticed this and Soviet scientists quickly developed a new landing algorithm. Tereshkova landed safely but received a bruise on her face.
She landed in the Altay region near today's Kazakhstan-Mongolia-China border. Villagers helped Tereshkova out of her spacesuit and asked her to join them for dinner. She accepted, and was later reprimanded for violating the rules and not undergoing medical tests first.

One thing we do know is that there are more elderly people alive now than there have ever been in the history of the planet. Even if today’s life-extension researchers made meaningful breakthroughs, the therapies wouldn’t be available for many years to come. That means we’re about to face a lot of death, says Rachel Maguire, a research director focusing on health care at the Institute for the Future, in Palo Alto. “By 2025 or 2030, there will be more of a culture of dying and lots of different ways of experiencing it. There are early signs of new types of funerals and spiritual formations around this.” Maguire foresees new end-of-life plans, including assisted dying. When it comes to aging, she points out that biological research is only one piece of a puzzle that must also include economics, politics and cultural change. “I don’t think we have answers yet for how we’d do the other pieces. And the financial piece alone is huge.”
There’s already a huge disparity between the life spans of rich and poor Americans, and critics of the new longevity research worry the gap may only grow wider.
In this nifty YouTube video, Dave Hax talks through the properties of gallium, the metal that liquefies at just 86ºF and is safe to play with. (Just don’t eat it!)
Hax has a whole collection of videos about gallium on his YouTube channel.
Boring vegetables need better marketing. That's the gist of a new study from Stanford university psychologists who gave cafeteria vegetables more "indulgent" names to see if students would buy them more often. Healthy labels ("wholesome," etc) didn't do well but indulgent labels ("sizzlin'", "dynamite," etc.) boosted vegetable sales by 25%. From the BBC:
"Association Between Indulgent Descriptions and Vegetable Consumption: Twisted Carrots and Dynamite Beets" (JAMA) Read the rest
The experiment took place over the whole of the autumn academic term. Each day, a vegetable dish was labelled up in one of four ways:
• basic - where the description was simply "carrots", for example
• healthy restrictive - "carrots with sugar-free citrus dressing"
• health positive - "smart-choice vitamin C citrus carrots"
• indulgent - "twisted citrus-glazed carrots"
...The indulgent labels came out top and included "twisted garlic-ginger butternut squash wedges" and "dynamite chilli and tangy lime-seasoned beets".
Seductive names resulted in 25% more people selecting the vegetable compared with basic labelling, 41% more people than the healthy restrictive labelling and 35% more people than the healthy positive labelling.
There's something magical about this 2014 video, which very suddenly goes from one YouTube genre (the intringuing at-home science experiment) to another (reality is disaster). You wonder why there aren't more of them out there! Read the rest
Republican Congressman Tim Walberg, hailing from the great state of Michigan, knows that climate change is real! Walberg does not think humans need worry though, GOD will take care of it.

“I believe there’s climate change,” Rep. Tim Walberg (R-MI) told constituents at a town hall Friday, as seen in a video of the event posted online. “I believe there’s been climate change since the beginning of time. I think there are cycles.”
“Do I think that man has some impact? Yeah, of course,” he continued. “Can man change the entire universe? No. Why do I believe that? As a Christian, I believe that there is a creator, God, who’s much bigger than us. And I’m confident that, if there’s a real problem, he can take care of it.”
Nesta's Juan Mateos-Garcia proposes that "entropic forces" make algorithmic decision-making tools worse over time, requiring that they be continuously maintained and improved (this is also a key idea from Cathy O'Neil's Weapons of Math Destruction: a machine-learning system is only honest if someone is continuously matching its predictions to reality and refining its model based on the mistakes it makes).

A University of Lincoln researcher on holiday in Morocco noticed that wildlife tourists were mistaking macaques' aggressive facial expressions for kissy faces and responding "by imitating the monkey's facial expression, which generally ended by either aggression by the monkey towards the tourists or the monkey leaving the interaction" -- which leads to monkey bites.

Olivia P. Judson's paper in Nature, The energy expansions of evolution, presents a novel, beautifully written and presented frame for looking at the history of life on Earth: as a series of five epochs in which energy became more abundant and available to lifeforms, allowing them to scale up in complexity and fecundity: geochemical energy, sunlight, oxygen, flesh and fire.

Beatboxer Tom Thum had ENT doctor and laryngeal surgeon Dr Matthew Broadhurst shine an endoscopic camera down his throat while beatboxing: "I wanted to find out how my larynx functioned when beatboxing compared to how it functions normally with speech, and whether or not there were any abnormalities in my laryngeal anatomy. I also had very little idea of what the inside of my throat and all my noise producing mechanisms actually looked like. The results were fascinating yet horrifyingly graphic and will probably make a few people spew in their laps." (via JWZ) Read the rest
