Molecular machines, much smaller than single cells, may one day be able to deliver drugs to kill cancer cells or patrol your body for signs of disease. But many applications of these machines require large arrays of rock-hard moving parts, which would be difficult to build with typical biological structures.
Nanomachines which can drill into cancer cells, killing them in just 60 seconds, have been developed by scientists. The tiny spinning molecules are driven by light, and spin so quickly that they can burrow their way through cell linings when activated. In one test conducted at Durham University the nanomachines
A study by MIT researchers shows that collections of ultracold molecules can retain the information stored in them for hundreds of times longer than previously achieved in these materials. These clusters might thus serve as “qubits,” the basic building blocks of quantum computers.
Chemists have largely ignored quantum mechanics. But it now turns out that this strange physics has a huge effect on biochemical reactions.
National Institute of Standards and Technology (NIST) physicists have solved the seemingly intractablepuzzle of how to control the quantum properties of individual charged molecules, or molecular ions. Thesolution is to use the same kind of “quantum logic” that drives an experimental NIST atomic clock.
The paradox of Schrödinger’s cat-in which a quantum cat is both alive and dead at the same time until we check to see which state it’s in-is arguably the most famous example of the bizarre counter-intuitive nature of the quantum world. Now, Stanford physicists have exploited this feature weirdness to make highly detailed movies of the inner machinery of simple iodine molecules.
Few of us really understand the weird world of quantum physics – but our bodies might take advantage of quantum properties
MIT researchers have adapted a technique known as expansion microscopy to visualize RNA molecules at high resolution in tissue samples. They have also made the technique easier to use, with off-the-shelf components.
Today, driven by ongoing technological innovations, the exploration of the “nanoverse,” as the realm of the minuscule is often termed, continues to gather pace. Paul Falkowski’s new book Life’s Engines: How Microbes Made Earth Habitable focuses on one of the most astonishing discoveries of the twentieth century-that our cells are comprised of a series of highly sophisticated “little engines” or nanomachines that carry out life’s vital functions.
Groundbreaking German research into the RNA molecule is giving hope of a major leap forward in the treatment of prostate cancer and other conditions
For the first time, researchers have reproduced the results of the Miller-Urey experiment in a computer simulation, yielding new insight into the effect of electricity on the formation of life’s building blocks at the quantum level.
(Phys.org) -Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
