Who is leading the private space race?
The space station sector has exciting potential as more private companies enter the conversation.
PETER WARD: When we think about the International Space Station we think of it rightly as the most expensive public project ever built in the entire history of humanity, but it's not just public anymore. There are a lot of private companies involved in it and in the future we could see a lot more private companies either on the International Space Station operating it or competing with it. The great thing about SpaceX and Blue Origin and other private companies making launch prices less costly means there's been a group of entrepreneurs that have come in behind them and they've been enabled in their mission. The transparency of the launch costs means that you can build a business plan now before you even go anywhere. And then you can get funding and then you can go. So there's a lot of smaller companies that are coming in behind SpaceX and Blue Origin which maybe you don't hear so much of, but doing fantastic things.
For example, NanoRacks is a company which is on the International Space Station right now. It has a really cool history of the company. Their CEO, a guy called Jeffrey Manber, he was actually in the negotiations between America and the Soviet Union over the International Space Station when it was first built. He was actually on the Russian side though because he saw Russia was going to get private space economy before America at that time. So, a really interesting character. He essentially what he does is he provides a service to anyone that wants it where they can launch a satellite or they can conduct experiments or use the International Space Station for research and they go through him rather than through NASA. So he owns a section of the International Space Station he essentially rents out and then any academic organization or country or anyone can go to NanoRacks and say we want to use this bit of space to do this research or we want to launch a satellite straight from the International Space Station. So that's a really cool company.
And there are several others in the space station. The space station sector is really fascinating because you have the International Space Station which is no one knows when it's going to happen but at some point it's going to be decommissioned or handed over to a private entity. So there are various companies that are either competing to become that private company that will take over the International Space Station or to launch their own International Space Station. And Jeffrey Manber at NanoRacks is one of those guys who wants to have a private space station. He wants to take the disused parts of rockets which go up and put them together and create a space station that way. There's Bigelow who has his inflatable modules who wants to make a space station that way possibly. And there's a few others. Axiom is a really serious organization. It's run by people who used to be in charge of the International Space Station for NASA so it's got some great expertise, it's got some great leaders.
I would say that the head of the race to – if a company were to take over the International Space Station it would probably be Axiom at this point. They're super serious. They know what they're doing and either they will take over the access or they'll launch their own. I think the one thing that they are doing is they've taken a kind of a – they're not going the inflatable route. They're going the way of building the entire space station on the ground and then sending it up which is quite expensive and not the most efficient. A lot of people would do it differently these days. There's more I guess innovative ways of doing it such as the inflatable modules and taking spent rocket parts and building it that way. But yes, they're the guys who know what they're doing. And then you have Orion Span which is a curious company. When I spoke to other people from the space station sector they didn't have the nicest things to say about Orion Span. I think they enjoy that there are more companies in the space. They enjoy the competition but what they don't want is people that aren't serious about it and don't have a serious business plan.
Orion Span says they're going to build a space station and they're going to take people to the space station on vacations. They're going to charge them I think it's $12 million. That is not possible to do and make a profit. It's completely impossible. Just to get people up there is going to cost millions. So that's not – when I spoke to people at the other companies they say it's great that have other companies involved but we don't want people who aren't serious and who don't have a serious business plan that are going to attract the headlines and also are going to attract money as well. Orion Span has gotten some alternative ways to get funding. They've gone the crowdfunding route. They've also got a cryptocurrency issue I think. I think you can donate to them in cryptocurrency. And it all comes across as this little not so serious to the guys who are already say on the ISS or who have worked on the ISS. Those guys don't see them as a serious competitor and I think what they are worried about is that it will be damaging overall to the mission. They will lose credibility because other companies are not as serious as they could be.

To create wiser adults, add empathy to the school curriculum.
- Stories are at the heart of learning, writes Cleary Vaughan-Lee, Executive Director for the Global Oneness Project. They have always challenged us to think beyond ourselves, expanding our experience and revealing deep truths.
- Vaughan-Lee explains 6 ways that storytelling can foster empathy and deliver powerful learning experiences.
- Global Oneness Project is a free library of stories—containing short documentaries, photo essays, and essays—that each contain a companion lesson plan and learning activities for students so they can expand their experience of the world.
Just before I turned 60, I discovered that sharing my story by drawing could be an effective way to both alleviate my symptoms and combat that stigma.
I've lived much of my life with anxiety and depression, including the negative feelings – shame and self-doubt – that seduced me into believing the stigma around mental illness: that people knew I wasn't good enough; that they would avoid me because I was different or unstable; and that I had to find a way to make them like me.
A joint study by two England universities explores the link between sex and cognitive function with some surprising differences in male and female outcomes in old age.
- A joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher cognitive abilities in older age.
- The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
- The differences in testosterone (the male sex hormone) and oxytocin (a predominantly female hormone) may factor into why the male cognitive level changes much more during sexual activity in older age.

To us humans, the shape and location of oceans and continents seems fixed. But that's only because our lives are so short.
Mathematicians studied 100 billion tweets to help computer algorithms better understand our colloquial digital communication.
- A group of mathematicians from the University of Vermont used Twitter to examine how young people intentionally stretch out words in text for digital communication.
- Analyzing the language in roughly 100 billion tweets generated over eight years, the team developed two measurements to assess patterns in the tweets: balance and stretch.
- The words people stretch are not arbitrary but rather have patterned distributions such as what part of the word is stretched or how much it stretches out.
