But if the tiny satellites do successfully work, similar low-cost satellites could be sent to other distant planets and moons, making communication with Earth from these deep reaches of space easier, and in some cases, possible at all.
When NASA lands a spacecraft on another planet, scientists generally need to have a “relay satellite” to beam images and measurements back to Earth.
Space exploration is hugely expensive, and cubesats could provide a much cheaper way to relay this information back home, rather than building and launching heavy spacecraft.

Today, we have an interview with Dr. Nichola Conlon, one of the speakers at the Undoing Aging 2018 Conference in Berlin, hosted by the Forever Healthy Foundation and SENS Research Foundation.
Introducing Nuchido
Dr. Conlon is the CEO of Nuchido, a new company that is set to launch later this year and was encouraged in part by four recent breakthroughs in biogerontology, which each showed rejuvenation in mammals [1–9]. These studies, which were all published in leading peer-reviewed scientific journals, showed that rejuvenation of aged animals was possible via different mechanisms of action.

Posthumous journal.
Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.
The paper, published today in the Journal of High Energy Physics, puts forward that the Universe is far less complex than current multiverse theories suggest.
It’s based around a concept called eternal inflation, first introduced in 1979 and published in 1981.

A new proof by SFI Professor David Wolpert sends a humbling message to would-be super intelligences: you can’t know everything all the time.
The proof starts by mathematically formalizing the way an “inference device,” say, a scientist armed with a supercomputer, fabulous experimental equipment, etc., can have knowledge about the state of the universe around them. Whether that scientist’s knowledge is acquired by observing their universe, controlling it, predicting what will happen next, or inferring what happened in the past, there’s a mathematical structure that restricts that knowledge. The key is that the inference device, their knowledge, and the physical variable that they (may) know something about, are all subsystems of the same universe. That coupling restricts what the device can know. In particular, Wolpert proves that there is always something that the inference device cannot predict, and something that they cannot remember, and something that they cannot observe.
“In some ways this formalism can be viewed as many different extensions of [Donald MacKay’s] statement that ‘a prediction concerning the narrator’s future cannot account for the effect of the narrator’s learning that prediction,’” Wolpert explains. “Perhaps the simplest extension is that, when we formalize [inference devices] mathematically, we notice that the same impossibility results that hold for predictions of the future—MacKay’s concern—also hold for memories of the past. Time is an arbitrary variable—it plays no role in terms of differing states of the universe.”

If space is an ocean, the International Space Station is a raft tethered to the shore. The moon is a nearby island that we’ve visited briefly. To go any further or stay any longer, humanity needs more power.
Now, NASA may have the source: A tiny nuclear reactor called KRUSTY, for Kilopower Reactor Using Stirling Technology. (If you’re wondering if this is may be a reference to a popular animated series, its predecessor was known as DUFF).
The reactor uses nuclear fission—the energy released by splitting uranium-235 in a reactor core about the size of a paper towel— to produce 10 kilowatts of power for about ten years, which NASA says is enough energy to power several houses. Four of the reactors could power an outpost on the lunar surface.

Believe it or not, a time crystal might actually exist, and its likeliest hiding place is within a child’s toy.
Fans of the Marvel cinematic universe might be shocked to know that a ‘time crystal’ does indeed have a basis in reality, but perhaps not so much as to be able to distort time itself.
Rather, the real-life time crystal is a form of matter that ‘ticks’ when exposed to an electromagnetic pulse, differing it from standard crystals.
