The magnetic resonance imaging (MRI) machines in hospitals are great at creating pictures of the human body. For decades, scientists have hoped that the same technology could be used to examine much smaller things, like individual molecules. Now, a team from Canada and the United States has revealed a new,…
A new microscope developed at the Marine Biological Laboratory in Woods Hole, Massachusetts is allowing scientists track the position and orientation of individual molecules in living cells. It has the potential to reveal unknown aspects of molecular behavior, including those that turn cells into agents of disease.
It’s becoming gradually easier to see what molecules look like up close, but seeing how their shape changes in real-time is still incredibly hard. Now, a new technique allows scientists to see how molecules change their shape over the course just trillionths of a second.
If engineers ever hope to build structures at the nanoscale, they’re going to need very, very tiny fingers. Or at least very tiny tools. By building a wrench that’s just 1.7 nanometers across, researchers from the University of Vermont have taken a critical step in that direction.
Since 1922, astronomers have been baffled as to the precise origin and composition of the diffuse interstellar bands seen through the Milky Way's stellar medium. This new interactive map doesn't solve the mystery, but it shows us exactly where these enigmatic molecules reside.
When a lot of us think about storage, we still think about that archaic method of encoding data by etching patterns into a disk. That's so 20th century. In the era of flash storage, researchers are now doing amazing things with chemical bonds—things like storing data on a single molecule.
There's a very commonly held view that atoms can never touch: bring them together slowly, and you reach a point where they begin to repel. But in this video, Professor Philip Moriarty explains that really isn't the case.
For the first time in history, scientists at Albert Einstein College of Medicine of Yeshiva University have captured how our brain makes memories in video, watching how molecules morph into the structures that, at the end of the day, make who we are. If there's a soul, this how it gets made.
When you bend anything, you stretch the bonds between atoms and force the little fellas to move about against their will. This image shows exactly that happening, inside a sheet of glass.
Microscopy is advancing in leaps and bounds these days. It was just last week that scientists produced the first image of a hydrogen atom’s orbital structure. Not to be outdone, Berkeley chemists have now captured a series of images showing molecules as they break and reform their chemical bonds. It looks almost...…
The building blocks of life could have their beginnings in the tiny icy grains that make up the gas and dust found between the stars, and those icy grains could be the key to understanding how life can arise on planets. With help from students, researchers have discovered an important pair of prebiotic molecules in…
You might think that sounds like a dumb question: why does it matter how many molecules there are, they just need to be cold enough, right? Wrong: you need enough to make the complex crystal structure that you see so clearly in snow flakes—and now scientists have worked out exactly how many that is.
If you've ever stuck your fingers together with super glue, you know pain. But imagine sticking them together with glue that bonds materials at the molecular level: that's real pain. It's also what scientists are doing, with the help of flesh-eating bacteria.
Think the Smart car was too small to squeeze your fat ass into? You're in for a whole new world of pain, because the smallest working car has been built — and it's just one molecule in size.
Science yields many rewards. There's the awed hush at nerd cocktail parties when you mention what you do, the sweet smell of urea in the morning, and the ability to name, or nickname, the things that you discover. Plenty of people name things after themselves. Some name them after their personal heroes, or their…
It was only two years ago that IBM showed us an image of a complete molecule, atomic bonds and all, but today's news does that one infinitesimally-sized breakthrough better. Ladies and gents, behold the first image of an electron's path.
Some day in the future, the PG5 molecule could save your life.
Swedish scientists have just discovered a new molecule—one that has the potential of boosting future rocket fuel efficiency by 20 to 30% compared to the best fuels around today.
Nevermind that banknotes are less than a millimeter thick, they're soon going to be stamped with electronic circuits for yet another anti-counterfeit measure. The notes will be traceable thanks to the semiconducting organic molecules, potentially putting a stop to bank-heists.
Thanks to quantum computing, we now have a fairly precise idea how much energy a hydrogen molecule gives off. Gone are the days when we had to guess this sort of thing by tossing atoms from hand to hand.
