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.
Chemists develop MRI technique for peeking inside battery-like devices
A team of chemists from New York University and the University of Cambridge has developed a method for examining the inner workings of battery-like devices called supercapacitors, which can be charged up extremely quickly ...
MRI for a quantum simulation
Magnetic resonance imaging (MRI), which is the medical application of nuclear magnetic resonance spectroscopy, is a powerful diagnostic tool. MRI works by resonantly exciting hydrogen atoms and measuring ...
How to better allocate research money and fix a flawed system
Taxpayers want to know that their money is well spent on research. Yet funding agencies persist in trying to explain research results in terms of papers and publications rather than in terms of people – ...
Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis
Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier.
Ear to the ground on shark sense
Research into how sharks hear is set to become the latest tactic to better understand and help prevent fatal shark attacks in Australian waters.
'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.
'Compressive sensing' provides new approach to measuring a quantum system
(Phys.org) —In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg's Uncertainty Principle, which says that both quantities cannot be ...
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.
Water caged in buckyballs
In a new paper in the Journal of Chemical Physics, a research team in the United Kingdom and the United States describes how water molecules "caged" in fullerene spheres ("buckyballs") are providing a deep ...
Artificial magnetic bacteria "turn" food into natural drugs
Scientists from the University of Granada have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach ...
Ceramic screws are corrosion and heat resistant
Most screws are made of steel. But high temperatures or acidic environments take their toll on this otherwise stable material. The alternative is ceramic screws. Researchers can now accurately predict their ...
MRI sensor that enables long-term monitoring of oxygen levels could aid cancer diagnosis, treatment
Unlike healthy cells, cancer cells thrive when deprived of oxygen. Tumors in low-oxygen environments tend to be more resistant to therapy and spread more aggressively to other parts of the body.
