On Mar. 7, elections in Sierra Leone marked a global landmark: the world’s first ever blockchain-powered presidential elections.

As president Ernest Bai Koroma leaves office after serving two five-year terms, the maximum allowed constitutionally, Sierra Leoneans have had to pick from a pool of 16 candidates including the ruling party’s Samura Kamara, the erstwhile foreign minister, and Julius Maada Bio, former military head of state and candidate of the main opposition party.

Results released by Sierra Leone’s election commission (NEC) suggest a run-off between Bio and Kamara is likely with neither candidate securing the required 55% of votes so far. Sierra Leone’s new president will be tasked with a continued rebuilding given the country’s recent major disasters. In 2014, an Ebola outbreak led to nearly 4,000 deaths and GDP losses estimated at $1.4 billion—a major loss for one of the world’s poorest countries. Last year Sierra Leone’s capital also suffered devastating flooding and mudslides believed to have claimed more than 1,000 lives.

Russia said today that it successfully launched a hypersonic missile capable carrying a nuclear warhead.

President Vladimir Putin called it ‘an ideal weapon’ when he unveiled a new array of next-generation arms earlier this month.

The high-speed, high-precision Kinzhal (Dagger) missile — capable of flying at almost 7,700mph across 1,250 miles — was launched from a MiG-31 supersonic interceptor jet that took off from an airfield in the South Military District in Russia’s southwest.

The idea of placing humans in stasis is one that has been explored in exhaustive detail through science fiction. Simply put it is the ability to quite literally press pause on our bodies and then wake up at an undefined time in the future.

While many (mostly millionaires) have tried and failed to perfect the technology it’s something that the US Military is now taking very seriously.

Its top secret research division known as DARPA has confirmed that it is now launching a Biostasis program where it will try to find a way of slowing the human body to an almost complete standstill.

When it comes to the future of space exploration, a number of new technologies are being investigated. Foremost among these are new forms of propulsion that will be able to balance fuel-efficiency with power. Not only would engines that are capable of achieving a great deal of thrust using less fuel be cost-effective, they will be able to ferry astronauts to destinations like Mars and beyond in less time.

This is where engines like the X3 Hall-effect thruster comes into play. This thruster, which is being developed by NASA’s Glenn Research Center in conjunction with the US Air Force and the University of Michigan, is a scaled-up model of the kinds of thrusters used by the Dawn spacecraft. During a recent test, this thruster shattered the previous record for a Hall-effect thruster, achieving higher power and superior thrust.

Hall-effect thrusters have garnered favor with mission planners in recent years because of their extreme efficiency. They function by turning small amounts of propellant (usually inert gases like xenon) into charged plasma with electrical fields, which is then accelerated very quickly using a magnetic field. Compared to chemical rockets, they can achieve top speeds using a tiny fraction of their fuel.

Yet several defense contractors are developing these engineering concepts for the U.S. military, hoping to get a piece of what is surely going to be a lucrative and lengthy contract.

Speaking to reporters at Lockheed Martin’s media day on Monday, CEO Marillyn Hewson touted investments in hypersonics, laser weapons, electronic warfare and artificial intelligence.

“Lockheed Martin has taken a leadership role in these four technology areas, and many others, to build an enterprise that can successfully support our customers’ rapidly evolving technology needs well into the future,” Hewson said.

The Pentagon is hoping to tap into the incredible survival techniques of some of nature’s hardiest creatures to ‘slow biological time’ on the battlefield.

DARPA’s new program, dubbed Biostasis, aims to develop ways to buy extra time for wounded soldiers between the moment of injury and first medical treatment.

This window, known as the ‘golden hour,’ is a critical for survival – but in reality, it’s often far less than sixty minutes.

Battlefield medics frequently only have a brief window of opportunity to treat an injury before it’s fatal or causes permanent disabilities, and it’s frequently so fleeting that there’s not much they can do. DARPA is exploring an unusual solution to that problem: slow the biological processes to give medics more room to breathe. Its new Biostasis research program aims to bring cell activity to a near halt by using biochemicals that control energetics at the protein level. If animals like tardigrades and wood frogs can stabilize their cells to survive freezing and dehydration, similar techniques might offer more time to medics who want to treat wounds before a victim’s vital systems break down.

DARPA knows this won’t be easy. The trick is to slow down every cellular process at roughly the same rate — you can’t just pause a few while others run at full speed. You’d also have to minimize any damage when the cells return to their normal function.

The Biostasis program is still very young (its first day for answering proposers’ questions is March 20th), and DARPA isn’t expecting too much even from complete projects: it’s initially focusing on “benchtop” proofs of concept and will focus on real-world uses as the program nears its 5-year end. If it has any success, though, the program could prove to be a breakthrough for the medical field as a whole, not just in combat. Paramedics could buy themselves enough time to get a patient to hospital, and doctors could focus less on basic survival and more on full recoveries.
