Lifeboat Foundation

Our mission is to preserve and disseminate humanity’s most important information across time and space, for the benefit of future generations.

But Altered Carbon is only the latest bit of transhumanism to hit TV recently. From Black Mirror’s cookies and Philip K. Dick’s Electric Dreams’ mind-invading telepaths and alien bodysnatchers to Star Trek: Discovery’s surgical espionage and Travelers’ time-jumping consciousness, the classic tropes of body-hopping, body-swapping, and otherwise commandeering has exploded in an era on the brink, one in which longevity technology is accelerating more rapidly than ever, all while most people still trying to survive regular threats to basic corporeal health and safety.

Nobody wants these dumb meat-sack bodies anymore. Now TV is asking if what replaces them will be any better.

A so-called ‘Starman,’ which is a life-size mannequin wearing a production version of the SpaceX crew spacesuit; a miniature car created by Hot Wheels to commemorate the Roadster and its primary passenger; and something called an Arch (pronounced “Ark”), which is not so easy to summarily describe.

The Arch on board is a data crystal (sort of like a Jedi Holocron if you’re mad for Star Wars lore) that contains all three books from Isaac Asimov’s classic Foundation trilogy. It’s actually a modest amount of data relative to the possibilities of the storage medium – in this case, a quartz silica structure which, using 5D optical storage techniques, can eventually achieve a max storage capacity of 360 terabytes on a disk just 3.75 inches in diameter.

But why shoot a tiny quartz disc into space? Why Foundation, and why aboard the Falcon Heavy, the crowning achievement of Elon Musk’s SpaceX private launch venture thus far?

EHang’s 184 air taxi is set to begin testing with passengers in Dubai and the state of Nevada.

The successful launch of the new rocket, the Falcon Heavy, by SpaceX from the Kennedy Space Centre in Florida into a Mars orbit around the Sun, has captured the world’s imagination and attention mainly because of its power but also because of its payload.

Famously aboard the spacecraft is a Tesla Roadster, owned by SpaceX CEO Elon Musk, but joining the bright red sports car on its journey around our solar system is the Arch Library, created using 5D optical storage technology developed by Professor Peter Kazansky and his team at the University of Southampton’s Optoelectronics Research Centre.

This first Arch library (pronounced Ark) – known as the Solar Library — contains the Foundation Trilogy of science fiction books written by Elon Musk’s favourite American author, Isaac Asimov… Archs are the vision of the Arch Mission Foundation which wants to permanently preserve and disseminate human knowledge as part of an ‘Encyclopedia Galactica’ across time and space for the benefit of future generations.

Quantum dots are rapidly taking center stage in emerging applications and research developments, from enhanced LCD TVs and thin-film solar cells, to high-speed data transfer and fluorescent labeling in biomedical applications.

You can’t peer very far down into a well or below the surface of the ocean before things go dark—light does not penetrate to such depths. Though the brain is far from bottomless, neuroscientists face the same lack of light when they try to study living deep-brain structures. This is especially frustrating given that optogenetics, a method for manipulating genetically tagged brain cells with light, has exploded in popularity over the past decade. “Optogenetics has been a revolutionary tool for controlling neurons in the lab, and hopefully someday in the clinic,” says Thomas McHugh, research group leader at the RIKEN Brain Science Institute in Japan. “Unfortunately, delivering light within brain tissue requires invasive optical fibers.”

McHugh and colleagues now have a solution for sending light to new depths in the brain. As they report in Science on February 9, upconversion nanoparticles (UCNPs) can act as a conduit for laser light delivered from outside the skull. These nanoparticles absorb near-infrared laser light and in turn emit visible photons to areas that are inaccessible to standard optogenetics. This method was used to turn on neurons in various brain areas as well as silence seizure activity and evoke memory cells. “Nanoparticles effectively extend the reach of our lasers, enabling the ‘remote’ delivery of light and potentially leading to non-invasive therapies,” says McHugh.

In optogenetics, blue-green light is used to turn neurons on or off via light-responsive ion channels. Light at these wavelengths, however, scatters strongly and is at the other end of the spectrum from the near-infrared light that can penetrate deeper into brain tissue. UCNPs composed of elements from the lanthanide family can act as a bridge. Their ‘optogenetic actuation’ turns low-energy near-infrared laser light into blue or green wavelengths for control of specifically labeled cells. Though such bursts of light deliver considerable energy to a small area, temperature increases or cellular damage were not observed.
