Hybrid Scanner Brings Molecular Functioning To The Forefront
A major barrier to developing a hybrid positron emission tomography/magnetic resonance imaging system could be removed by using a novel approach for reconstructing data, according to researchers.
Researchers create method to precisely glue particles together on nano-scale
Researchers at New York University have created a method to precisely bind nano- and micrometre-sized particles together into larger-scale structures with useful materials properties. Their work, which appears in the...
The Earth's magnetic field remains a charged mystery
400 years of discussion and we're still not sure what creates the Earth's magnetic field, and thus the magnetosphere, despite the importance of the latter as the only buffer between...
SPECT provides high-quality images of small tumours
A new study shows that combining high resolution and high sensitivity collimation provides better quality images when using single photon emission computed tomography (SPECT) scans, said researchers at SNM's 56th...
New approach in the quest for lighting's Holy Grail
Researchers are reporting the first use of a fundamentally new approach in the quest to snare the Holy Grail of the lighting industry: An LED (light-emitting diode) - those ultra-efficient,...

Charge on single atoms measured
Researchers have demonstrated a new method to measure the charge of individual atoms on a variety of materials.
Tunable Graphene Bandgap Opens The Way To Nanoelectronics And Nanophotonics
Graphene's electrical properties include electrons so mobile they travel at near light speed. But without a bandgap, graphene's promise for electronics and photonics can't be realized. Now researchers can precisely...
Science Weekly with Michio Kaku: Impossibility is relative
In the second of our small but perfectly realised holiday specials, we squint into the future to distinguish the possible from the impossible in the world of physics. You might...
Advance In Understanding Cellulose Synthesis
Cellulose makes up plant cell walls, gives plants shape and form and is a target of renewable, plant-based biofuels research. But how it forms, and thus how it can be...
