Many scientists research the practical and immediate applications of bio molecular technology but it seems most fail to study our most important, and largest organ, our skin.

Who will officially be the first transhuman? Will it be you? Why wait decades? This article explains one approach to speeding up the process and also the challenge involved.

Defining the Object of the Goal:

Although the words ‘cyborg’ and ‘transhuman’ are often used interchangeably, and someone can aspire to be a combination of both, there are fundamental differences between the two — as has been articulated by Dr. Natasha Vita-More: The transhuman will be genetically programmed and otherwise equipped towards indefinite life extension and to attain a great many other physical and mental capabilities and other benefits. The transhuman also maintains specific transhumanist values and may actively foster the far-reaching humane goals of the transhumanist movement, including guaranteed social justice for all and highly-advanced space colonization to foster indefinite life, peace, etc. Whereas, a cyborg may not uphold transhuman values or goals, and may or may not seek to live longer or indefinitely, but will be fitted with a device or devices to acquire one or more enhanced capabilities (such as better vision and/or hearing, faster running ability, etc.).

Rice University physicists have created the world’s first laser-cooled neutral plasma, completing a 20-year quest that sets the stage for simulators that re-create exotic states of matter found inside Jupiter and white dwarf stars.

The findings are detailed this week in the journal Science and involve new techniques for cooling clouds of rapidly expanding to temperatures about 50 times colder than deep space.

“We don’t know the practical payoff yet, but every time physicists have laser cooled a new kind of thing, it has opened a whole world of possibilities,” said lead scientist Tom Killian, professor of physics and astronomy at Rice. “Nobody predicted that laser cooling atoms and ions would lead to the world’s most accurate clocks or breakthroughs in quantum computing. We do this because it’s a frontier.”

As if battered post-Christmas finances, a looming disorderly Brexit and the prospect of a fresh nuclear arms race were not enough to dampen spirits, astronomers have declared that a nearby galaxy will slam into the Milky Way and could knock our solar system far into the cosmic void.

The unfortunate discovery was made after scientists ran computer simulations on the movement of the Large Magellanic Cloud (LMC), one of the many satellite galaxies that orbits the Milky Way. Rather than circling at a safe distance, or breaking free of the Milky Way’s gravitational pull, the researchers found the LMC is destined to clatter into the galaxy we call home.

At the moment, the LMC is estimated to be about 163,000 light years from the Milky Way and speeding away at 250 miles per second. But simulations by astrophysicists at Durham University show that the LMC will eventually slow down and turn back towards us, ultimately smashing into the Milky Way in about 2.5 billion years’ time.

China has become the first nation in history to land a spacecraft on the far side of the moon, state media announced on Thursday.

Thursday’s official televised announcement that the probe had landed came approximately an hour after state media outlets China Daily and China Global Television Network (CGTN) deleted posts on social media proclaiming the mission a success, sparking widespread confusion as to whether the probe had in fact had made touchdown.

No explanation was given as to why the earlier tweets were deleted. On social media, observers speculated as to the cause of the apparent backtracking, with many wondering if the mission had experienced a temporary upset, or whether it was a simple case of state media jumping the gun ahead of the official announcement.

China’s last lunar rover — named Yutu, or Jade Rabbit — ceased operation in August 2016 after 972 days of service on the moon’s surface as part of the Chang’e 3 mission. China was only the third nation to carry out a lunar landing, after the United States and Russia.

The Cray-1 supercomputer, the world’s fastest back in the 1970s, does not look like a supercomputer. It looks like a mod version of that carnival ride The Round Up, the one where you stand, strapped in, as it dizzies you up. It’s surrounded by a padded bench that conceals its power supplies, like a cake donut, if the hole was capable of providing insights about nuclear weapons.

After Seymour Cray first built this computer, he gave Los Alamos National Laboratory a six-month free trial. But during that half-year, a funny thing happened: The computer experienced 152 unattributable memory errors. Later, researchers would learn that cosmic-ray neutrons can slam into processor parts, corrupting their data. The higher you are, and the bigger your computers, the more significant a problem this is. And Los Alamos—7,300 feet up and home to some of the world’s swankiest processors—is a prime target.

The world has changed a lot since then, and so have computers. But space has not. And so Los Alamos has had to adapt—having its engineers account for space particles in its hard- and software. “This is not really a problem we’re having,” explains Nathan DeBardeleben of the High Performance Computing Design group. “It’s a problem we’re keeping at bay.”
