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.

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.

China is intensifying its push into space, and broadening its astronaut recruiting.

The Chinese government, which plans to increase the number of manned missions in its military-backed space program to around two a year, will soon begin recruiting civilian astronauts, Yang Liwei, deputy director of the China Manned Space Engineering Office, told reporters on the sidelines of a ceremonial parliament session this weekend. That’s a departure from China’s practice of drawing its astronauts from among air force pilots.

Yang—who was China’s first man in space in 2003—said the trainees could include private-sector maintenance engineers, payload specialists, pilots, scientists, and people from universities and other research institutions, according to the Associated Press. More women are also being encouraged to apply. The loosening of restrictions comes amid NASA’s announcement that it has recruited America’s most competitive class of astronauts ever, as well as other initiatives like Canada’s Hunger Games -style search for new astronauts on the internet.

That’s not a lot to you. If your watch is off by 13.7 microseconds, you’ll make it to your important meeting just fine. But it wasn’t so nice for the first-responders in Arizona, Pennsylvania, Connecticut, and Louisiana, whose GPS devices wouldn’t lock with satellites. Nor for the FAA ground transceivers that got fault reports. Nor the Spanish digital TV networks that had receiver issues. Nor the BBC digital radio listeners, whose British broadcast got disrupted. It caused about 12 hours of problems—none too huge, all annoying. But it was a solid case study for what can happen when GPS messes up.

The 24 satellites that keep GPS services running in the US aren’t especially secure; they’re vulnerable to screw-ups, or attacks of the cyber or corporeal kind. And as more countries get closer to having their own fully functional GPS networks, the threat to our own increases. Plus, GPS satellites don’t just enable location and navigation services: They also give ultra-accurate timing measurements to utility grid operators, stock exchanges, data centers, and cell networks. To mess them up is to mess those up. So private companies and the military are coming to terms with the consequences of a malfunction—and they’re working on backups.

The 2016 event was an accidental glitch with an easily identifiable cause—an oops. Harder to deal with are the gotchas. Jamming and spoofing, on a small scale, are both pretty cheap and easy. You can find YouTube videos of mischievous boys jamming drones, and when Pokemon GO users wanted to stay in their parents’ basements, they sent their own phones fake signals saying they were at the Paris mall. Which means countries, and organized hacking groups, definitely can mess with things on a larger scale. Someone can jam a GPS signal, blocking, say, a ship from receiving information from satellites. Or they can spoof a signal, sending a broadcast that looks like a legit hello from a GPS satellite but is actually a haha from the hacker next-door.

Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of ‘Operation Castle’.

The operation’s ultimate objective was to test designs for a powerful nuclear weapon that could be delivered by aircraft.

The researchers also suggested that aliens could “gift” us with an artificial intelligence (AI) system that may trick humans into developing self-replicating nanobots and eventually deploy them to wreak havoc on our planet. The researchers argue that it would be cheaper for aliens to “send a malicious message to eradicate humans compared to sending battleships”.

In one scenario, the researchers argued that a message from aliens could be a panic-inducing statement like “We will make your sun go supernova tomorrow”. According to the researchers, if such a threatening message is received in just one location, it may be possible to contain and even destroy it. “If it is received repeatedly, perhaps even by amateurs, containment is impossible,” the researchers wrote in a paper available online on arXiv.

In another scenario, the scientists argue that humans could be tricked into begetting their own demise by aliens offering the “gift” of knowledge. For instance, aliens could transmit a message that reads: “We are friends. The galactic library is attached. It is in the form of an artificial intelligence (AI) which quickly learns your language and will answer your questions. You may execute the code following these instructions…”

Critics of the militarization of marine life say the problem with a new DARPA program is moral, not practical.

WASHINGTON ― Rapid advances in artificial intelligence and military robotics have some concerned that the development of Terminator-like killer robots will be humankind’s downfall. But that doesn’t seem to worry Eric Schmidt, the former executive chairman of Google parent company Alphabet, who addressed the impact of technology on democracy at the Feb. 16–18 Munich Security Conference.
