Might-power-the-next-generation-of-quantum-computing-4455118/

Scientists have developed a way to mass-produce tiny diamond crystals shaped like needles and threads, which may power next generation of quantum computing. Physicists from the Lomonosov Moscow State University in Russia have described structural peculiarities of micrometre-sized diamond crystals in needle and thread-like shapes, and their interrelation with luminescence features and field electron emission efficiency.

For the first time since the advent of stem cell therapy, a team of scientists from the North Carolina State University, the University of North Carolina at Chapel Hill and First Affiliated Hospital of Zhengzhou University, was able to implant synthetic cardiac stem cells which effectively repaired muscle tissue that got damaged by a heart attack. Typically, heart muscles that get scarred from a heart attack will either stay as is or get worse, but not improve. With the synthetic stem cell implant done, however, the result was a remarkable contradiction. Details about this new technique that is supposedly less risky than traditional stem cell procedures were recently published in the ‘Nature Communications’ journal.

Stem cell therapy works by helping damaged tissue repair itself. Although this type of treatment can be effective, it comes with certain types of risks, most notably, immune system rejection and cancerous growths. And, the process itself is very delicate because natural stem cells are quite fragile, have to be stored carefully, and must undergo a series of typing and matching prior to being used.

It is these limitations that have prompted scientists to come up with a different approach to make stem cell therapy work better. And what they developed was a procedure involving synthetic stem cells.

Older than Sumerian script? The Danube Valley civilization is one of the oldest civilizations known in Europe. It existed from between 5,500 and 3,500 BC in the Balkans and covered a vast area, in what is now Northern Greece to Slovakia (South to North), and Croatia to Romania (West to East).

During the height of the Danube Valley civilization, it played an important role in south-eastern Europe through the development of copper tools, a writing system, advanced architecture, including two storey houses, and the construction of furniture, such as chairs and tables, all of which occurred while most of Europe was in the middle of the Stone Age. They developed skills such as spinning, weaving, leather processing, clothes manufacturing, and manipulated wood, clay and stone and they invented the wheel. They had an economic, religious and social structure.

New version of this out: https://www.geneticliteracyproject.org/2017/01/02/americas-r…-cold-war/ #transhumanism #biohacking

Unlike other epic scientific advances…the immediate effect of genetic editing technology is not dangerous. Yet, it stands to be just as divisive to humans as the 70-year proliferation of nuclear weaponry.

The playing field of geopolitics is pretty simple: If China or another country vows to increase its children’s intelligence via genetic editing, and America chooses to remain “au naturel” because they insist that’s how God made them, a conflict species-deep will quickly arise.

This type of idea takes racism and immigration to a whole new level. Will America close off its borders, its jobs, its schools, and its general openness to the world to stay pure, old-fashioned human?

In a breakthrough for regenerative medicine, scientists have grown intestinal tissues with functional nerves in a laboratory setup using human pluripotent stem cells. The synthesized tissue was used to study Hirschsprung’s disease, a congenital condition where nerve cells are missing from the colon, causing complications in passing stool. The research is detailed in Nature Medicine.

A pluripotent stem cell is a precursor cell to all the other types of cells in the body. In a petri dish, the stem cells were treated in a biochemical bath that triggered the formation into intestinal tissue. The novel part of the study was the construction of a nervous system on the intestinal organoid. The researchers manipulated neural crest cells to grow a system of nerves. By putting together the neural crest cells and the intestinal tissue at the exact time, they successfully grew together into a complex functional system.

The tissues were transplanted into mice. They worked successfully and showed a structure “remarkably similar” to that of a natural human intestine.

Scientists at Karolinska Institutet and the University of Gothenburg have generated a web-based software, Green Listed, which can facilitate the use of the CRISPR methodology. The software is published in the journal Bioinformatics and is freely available through greenlisted.cmm.ki.se where also information texts and films are available.

Cells are very small and builds up an organism. A human has about 100 times as many in its body as there are people on earth. Inside a vast majority of these cells are long chains of DNA. These DNA chains affects how different cells look and behave. CRISPR is a research method that can be used to rapidly study how different portions of the DNA directly affect cells. Using this method, researchers can gain insights to the cause of diseases and give suggestions for how they can be treated.

“We use the CRISPR methodology to study both and . The goal is to develop new treatments for patients with diseases related to the immune system, such as arthritis, as well as cancer”, says Fredrik Wermeling at the Center for Molecular Medicine (CMM), Department of Medicine, Karolinska Institutet.

In Brief

  • Kawasaki is developing AI for future bikes that will give it a personality with the hopes it will help reassure drivers.
  • AI is constantly being developed in new ways, ranging from the novel to the revolutionary.

Automotive company Kawasaki Heavy Industries, Ltd. (KHI) is developing next-generation motorcycles with an AI controlled-system that not only ensures safer rides, but also develops an emotional connection with the user.

The bikes use a system called the “Emotion Generation Engine and Natural Language Dialogue System”, developed by robotics teams from cocoro SB Corp. The driver can talk to the bike and it will be able to pick up cues on the rider’s emotional state and intents. In their press release, Kawasaki said that this “will open the door to a new world of unprecedented riding experiences.”

NASA researchers have a lot of problems to work through if they want astronauts to one day set foot on Mars. One of the biggest hurdles is where these early pioneers will sleep and live, and after a day of brainstorming, engineers might have come up with a solution – a conceptual ‘ice home’ design.

Yup, NASA is looking into creating inflatable domes covered in ice for astronauts to live and work in, providing them with protection from extreme temperatures and high-energy radiation.

“After a day dedicated to identifying needs, goals, and constraints we rapidly assessed many crazy, out of the box ideas and finally converged on the current Ice Home design, which provides a sound engineering solution,” said senior systems engineer Kevin Vipavetz, from NASA’s Langley Research Centre in Virginia.
