'Nanojuice' could improve how doctors examine the gut
Located deep in the human gut, the small intestine is not easy to examine. X-rays, MRIs and ultrasound images provide snapshots but each suffers limitations. Help is on the way.
Nanoscale composites improve MRI: Researchers merge magnetic particles to detect, fight disease
(Phys.org) —Submicroscopic particles that contain even smaller particles of iron oxide could make magnetic resonance imaging (MRI) a far more powerful tool to detect and fight disease.
Impurity size affects performance of emerging superconductive material
Research from North Carolina State University finds that impurities can hurt performance – or possibly provide benefits – in a key superconductive material that is expected to find use in a host of applications, ...
MRI, on a molecular scale: Team develops system that could peer into atomic structure of individual molecules
For decades, scientists have used techniques such as X-ray crystallography and nuclear magnetic resonance (NMR) imaging to gain invaluable insight into the atomic structure of molecules. Such efforts have ...
Manipulating electron spin mechanically
(Phys.org) —Contrary to many textbook illustrations, electrons aren't just balls floating around an atom. In quantum theory, they're more like little tops, exhibiting "spin," and each creating its own tiny ...
Chemists use MRI to peek at temperatures of gases inside catalytic reactors
UCLA chemists for the first time have employed magnetic resonance imaging (MRI)—a technique normally reserved for medical clinicians peering inside the human body—to better measure the temperature of ...
Precocious GEM: Shape-shifting sensor can report conditions from deep in the body
Scientists working at the National Institute of Standards and Technology and the National Institutes of Health have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human ...
Scientists discover new information about how enzymes from white blood cells function
As a part of the human immune system, white blood cells create a number of enzymes that help fight disease. Sometimes, these enzymes damage tissues in inflammatory diseases such as chronic obstructive pulmonary disease, cancer ...
Nanoparticles that enable both MRI and fluorescent imaging could monitor cancer, other diseases
MIT chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging (MRI) and fluorescent imaging in living animals. Such particles could help scientists to track specific ...
Liberal or conservative? Reactions to disgust are a dead giveaway
Maggot infestations, rotting carcasses, unidentifiable gunk in the kitchen sink – how much your brain responds to disgusting images could predict whether you are liberal or conservative.
Extremely high-resolution magnetic resonance imaging
For the first time, researchers have succeeded to detect a single hydrogen atom using magnetic resonance imaging, which signifies a huge increase in the technology's spatial resolution. In the future, single-atom ...
Research band at Karolinska tuck Dylan gems into papers
Synthesis produces new antibiotic: Scientists confirm potent synthesis of natural tetracycline
A fortuitous collaboration at Rice University has led to the total synthesis of a recently discovered natural antibiotic.
New cancer-hunting 'nano-robots' to seek and destroy tumours
It sounds like a scene from a science fiction novel – an army of tiny weaponised robots travelling around a human body, hunting down malignant tumours and destroying them from within.
