Study shows continuous dehydration kills cells during dry preservation
Posted by Karen Hurst in categories: cryonics, engineering, life extension
A new finding in experiments studying the dry preservation of living cells — a potentially revolutionary alternative to cryopreservation — has defined a clear limit where continuing dehydration kills cells. The data, combined with molecular dynamics simulations, provides insight into an important processing factor that has limited recent attempts at dry preservation.
“What we have done is identified what appears to be a materials constraint in our method of dry preservation. I think this new understanding suggests some interesting avenues to pursue in developing a successful process,” said Gloria Elliott, Professor of Mechanical Engineering at the University of North Carolina at Charlotte, one of the study’s authors.
The findings, reported in the July 8 issue of Scientific Reports, analyzes changes in the molecular arrangements of trehalose (a sugar) and water molecules during a typical dehydration process that they use to immobilize cells in a stable trehalose glass for long-term storage.

Here’s a concept; you’re next open house showing is conducted by a robot.
UAE marketers get a first glimpse of the humanoid robot Pepper.
A temporary tattoo that can read your emotions. Could this be a new method used for events to id possible problem people. Of course, more work is needed and costs will need to improve; however, is this another tool to help id possible mass murderers, etc.?
The new Israeli-designed skin electrode, affixed to the skin just like a temporary tattoo, can monitor emotions and restore damaged tissue.

Electron spin control: Levitated nanodiamond is research gem
Posted by Karen Hurst in categories: nanotechnology, quantum physics
I’m telling folks there is much to be learn in the usage of natural and synthetic resources especially around diamonds — Nanodiamonds Magic.
WEST LAFAYETTE, Ind. — Researchers have demonstrated how to control the “electron spin” of a nanodiamond while it is levitated with lasers in a vacuum, an advance that could find applications in quantum information processing, sensors and studies into the fundamental physics of quantum mechanics.
Electrons can be thought of as having two distinct spin states, “up” or “down.” The researchers were able to detect and control the electron spin resonance, or its change from one state to the other.

World’s Smallest Hard Drive Writes Data Atom-By-Atom
Posted by Karen Hurst in categories: computing, nanotechnology, particle physics
Meet the world’s smallest hard drive.
Dutch scientists have developed a unique solution to deal with the data storage problem. By manipulating single atoms, researchers have created the world’s smallest hard drive capable of storing 1 kilobyte of data (8000 bits) in a space under 100 nanometers across. The technology means that all the books in the world could be stored on a device the size of a postage stamp.
In a study published Monday in the journal Nature Nanotechnology, scientists from the Technical University of Delft (TU Delft) said that they have created an atomic hard drive with a storage density that is 500 times greater than current hard drive technology.

Quantum computers show potential to revolutionize chemistry

Like this feature on QC.
If you have trouble wrapping your mind around quantum physics, don’t worry — it’s even hard for supercomputers. The solution, according to researchers from Google, Harvard, Lawrence Berkeley National Laboratories and others? Why, use a quantum computer, of course. The team accurately predicted chemical reaction rates using a supercooled quantum circuit, a result that could lead to improved solar cells, batteries, flexible electronics and much more.
Chemical reactions are inherently quantum themselves — the team actually used a quote from Richard Feynman saying “nature isn’t classical, dammit.” The problem is that “molecular systems form highly entangled quantum superposition states, which require many classical computing resources in order to represent sufficiently high precision,” according to the Google Research blog. Computing the lowest energy state for propane, a relatively simple molecule, takes around ten days, for instance. That figure is required in order to get the reaction rate.

Post-Quantum Cryptography Aims To Fend Off Advanced Hack Attacks
Posted by Karen Hurst in categories: cybercrime/malcode, encryption, internet, quantum physics
Luv it; more believers.
Quantum computers promise to enable faster, far more complex calculations than today’s silicon chip-based computers. But they also raise the possibility that future computers could retroactively break the security of any digital communications that exist today, which is why Google is experimenting with something called “post-quantum cryptography.”
While quantum computer development remains in its early stages, some such computers are already in operation. In theory, future generations of quantum computers could “decrypt any Internet communication that was recorded today, and many types of information need to remain confidential for decades,” software engineer Matt Braithwaite wrote yesterday in a post on Google’s security blog. “Thus even the possibility of a future quantum computer is something that we should be thinking about today.”

Weird quantum effects travel over hundreds of miles

I shared this yesterday; however, another article with another spin (no pun intended)
Working at the Massachusetts Institute of Technology’s (MIT) Fermilab physics laboratory in Illinois, a team of physicists studied the states of neutrinos, among the smallest components of an atom.
