How close are we really to space travel? Our featured contributor Lola Akinmade Åkerström talks to Space Nation, a company that’s researching both space tourism and how space technology can help us on Earth.

Thanks to Google, it can often feel like there are no mysterious places left on earth to explore—and finding new places to call the ‘final’ frontier seems increasingly difficult. Even the Pacific Ocean’s Marianna Trench, at over 36,000 feet deep and arguably the most legit final frontier on earth, has been explored by Hollywood director James Cameron in a submersible. As a result, the past few decades have seen us looking upwards to the most mysterious of places: Our own galaxy.

Blockbuster movies set in space and fictional alien encounters continue to intrigue us. Space discovery programs on TV science channels continually pique our curiosity. Even kids’ cartoons such as the 1960s American series The Jetsons brought the concept of commercial space travel closer to us, thanks to its flying space cars, pod-like apartments, and a robot maid called Rosie.

The University of Nebraska College of Law is joining forces with space and military law experts from Australia and the United Kingdom to take the lead on understanding how our Earth-bound laws will be applied in times of armed conflict in outer space.

Some of the best legal and policy minds at the University of Adelaide, UNSW Canberra, University of Exeter and Nebraska Law will draft the definitive document on military and security law as applied to space.

The Woomera Manual on the International Law of Military Space Operations is to be completed in 2020. It will draw on the knowledge of dozens of legal and space operations experts from around the world.

Take any two cells from your body and there’s a good chance their genetic sequences will be a match. That is, unless you happen to have what’s referred to in the medical literature as a ‘tetragametic chimerism’ – a condition that causes separate fertilised embryos to merge into a single body.

Once thought to be rare among humans, there’s good reason to suspect we might be seeing a lot more of it in the future.

The truth is, nobody is really certain how many humans have cells in their body that once belonged to a sibling.

In the summer of 1935, the physicists Albert Einstein and Erwin Schrödinger engaged in a rich, multifaceted and sometimes fretful correspondence about the implications of the new theory of quantum mechanics. The focus of their worry was what Schrödinger later dubbed entanglement: the inability to describe two quantum systems or particles independently, after they have interacted.

Until his death, Einstein remained convinced that entanglement showed how quantum mechanics was incomplete. Schrödinger thought that entanglement was the defining feature of the new physics, but this didn’t mean that he accepted it lightly. “I know of course how the hocus pocus works mathematically,” he wrote to Einstein on July 13, 1935. “But I do not like such a theory.” Schrödinger’s famous cat, suspended between life and death, first appeared in these letters, a byproduct of the struggle to articulate what bothered the pair.

The problem is that entanglement violates how the world ought to work. Information can’t travel faster than the speed of light, for one. But in a 1935 paper, Einstein and his co-authors showed how entanglement leads to what’s now called quantum nonlocality, the eerie link that appears to exist between entangled particles. If two quantum systems meet and then separate, even across a distance of thousands of lightyears, it becomes impossible to measure the features of one system (such as its position, momentum and polarity) without instantly steering the other into a corresponding state.

It’s time to rethink the quest to control aging, death, and disease—and the fear of mortality that fuels it.

I went to medical school, at least in part, to get to know death and perhaps to make my peace with it. So did many of my doctor friends, as I would find out. One day—usually when you’re young, though sometimes later—the thought hits you: You really are going to die. That moment is shocking, frightening, terrible. You try to pretend it hasn’t happened (it’s only a thought, after all), and you go about your business, worrying about this or that, until the day you put your hand to your neck—in the shower, say—and … What is that? Those hard lumps that you know, at first touch, should not be there? But there they are, and they mean death. Your death, and you can’t pretend anymore.

I never wanted to be surprised that way, and I thought that if I became a doctor and saw a lot of death, I might get used to it; it wouldn’t surprise me, and I could learn to live with it. My strategy worked pretty well. Over the decades, from all my patients, I learned that I would be well until I got sick and that although I could do some things to delay the inevitable a bit, whatever control I had was limited. I learned that I had to live as if I would die tomorrow and at the same time as if I would live forever. Meanwhile, I watched as what had been called “medical care”—that is, treating the sick—turned into “health care,” keeping people healthy, at an ever-rising cost.

If physicists do find that gravitational waves have travelled through dimensions other than the four we live in, it will be the start of a revolution in physics. But how close are we really?

Alzheimer’s gene is neutralised in human brain cells for the first time.

Just two copies of this gene can increase your risk 12-fold.
