You could soon be manufacturing your own drugs—thanks to 3D printing
Posted by Derick Lee in categories: 3D printing, biotech/medical, chemistry
But it remains to be seen whether drug regulators will go along with a new way of making medicines. To do so, agencies like the U.S. Food and Drug Administration will need to rewrite their rules for validating the safety of medicines. Instead of signing off on the production facility and manufactured drug samples, regulators would have to validate that reactionware produces the desired medication. Cronin agrees it’s a hurdle. But he argues that future printed reactors could simply include a final module containing standard validation tests that produce a visual readout, much like a pregnancy test. “I think it’s manageable.”
Digitized chemistry on demand could also undermine drug counterfeiters.

Liquid metal discovery ushers in new wave of chemistry and electronics
Posted by Saúl Morales Rodriguéz in categories: chemistry, computing, particle physics
Researchers from RMIT University in Melbourne, Australia, have used liquid metal to create two-dimensional materials no thicker than a few atoms that have never before been seen in nature.
The incredible breakthrough will not only revolutionise the way we do chemistry but could be applied to enhance data storage and make faster electronics. The “once-in-a-decade” discovery has been published in Science.
The researchers dissolve metals in liquid metal to create very thin oxide layers, which previously did not exist as layered structures and which are easily peeled away.

A Rare Element From The Edge of The Periodic Table Is Breaking Quantum Mechanics
Posted by Shailesh Prasad in categories: chemistry, quantum physics
There’s a lot we don’t know about the actinides. On the periodic table, this series of heavy, radioactive elements hangs at the bottom, and includes a host of mysterious substances that don’t naturally occur on Earth.
Among this cast of unknowns, berkelium looks to be even stranger than we realised. New experiments with this incredibly rare synthetic element have shown that its electrons don’t behave the way they should, defying quantum mechanics.
“It’s almost like being in an alternate universe because you’re seeing chemistry you simply don’t see in everyday elements,” says chemist Thomas Albrecht-Schmitt from Florida State University.

Nobel Prize in Chemistry 2017 Awarded for Cryo-Electron Microscopy
Posted by Shailesh Prasad in categories: biological, chemistry, nanotechnology
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2017 to Jacques Dubochet (University of Lausanne, Switzerland), Joachim Frank (Columbia University, New York, USA) and Richard Henderson (MRC Laboratory of Molecular Biology, Cambridge, UK) “for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution”.
We may soon have detailed images of life’s complex machineries in atomic resolution. The Nobel Prize in Chemistry 2017 is awarded to Jacques Dubochet, Joachim Frank and Richard Henderson for the development of cryo-electron microscopy, which both simplifies and improves the imaging of biomolecules. This method has moved biochemistry into a new era.
A picture is a key to understanding. Scientific breakthroughs often build upon the successful visualisation of objects invisible to the human eye. However, biochemical maps have long been filled with blank spaces because the available technology has had difficulty generating images of much of life’s molecular machinery. Cryo-electron microscopy changes all of this. Researchers can now freeze biomolecules mid-movement and visualise processes they have never previously seen, which is decisive for both the basic understanding of life’s chemistry and for the development of pharmaceuticals.

Fundamental Particles & Forces: What do we know?
Posted by Philip Raymond in categories: chemistry, general relativity, particle physics, physics, quantum physics, science
Do you remember all the hoopla last year when the Higgs Boson was confirmed by physicists at the Large Hadron Collider? That’s the one called the ‘God particle’, because it was touted as helping to resolve the forces of nature into one elegant theory. Well—Not so fast, bucko!…
First, some credit where credit is due: The LHC is a 27-kilometer ring of superconducting magnets interspersed by accelerators that boost the energy of the particles as they whip around and smash into each other. For physicists—and anyone who seeks a deeper understanding of what goes into everything—it certainly inspires awe.
Existence of the Higgs Boson (aka, The God Particle) was predicted. Physicists were fairly certain that it would be observed. But its discovery is a ‘worst case’ scenario for the Standard Model of particle physics. It points to shortcomings in our ability to model and predict things. Chemists have long had a master blueprint of atoms in the Periodic Table. It charts all the elements in their basic states. But, physicists are a long way from building something analogous. That’s because we know a lot more about atomic elements than the fundamental building blocks of matter and energy. [continue below image]

Ray Kurzweil — A Revolutionary Future
Posted by Alexander Rodionov in categories: biotech/medical, chemistry, life extension, nanotechnology, Ray Kurzweil, robotics/AI, singularity, transhumanism
https://www.youtube.com/watch?v=dLgJZ-yNBBE&feature=share
Kurzweil is one of the world’s leading minds on artificial intelligence, technology and futurism. He is the author of five national best-selling books, including “The Singularity is Near” and “How to Create a Mind.”
Raymond “Ray” Kurzweil is an American author, computer scientist, inventor and futurist. Aside from futurology, he is involved in fields such as optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He has written books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism. Kurzweil is a public advocate for the futurist and transhumanist movements, and gives public talks to share his optimistic outlook on life extension technologies and the future of nanotechnology, robotics, and biotechnology.
