Scientists are investigating how to tailor drug therapies using exosomes - nanoscale sacs full of biomarkers like lipids, proteins and nucleic acids found in bodily fluids - that can be used to achieve a noninvasive 'liquid biopsy'.
A international team of researchers has discovered magnetic vortex-antivortex pairs arising from correlated electron spins in a newly engineered trilayer material. The discovery could advance memory cells and points to the potential development of 3-D magnetic logic circuits.
Physicists have demonstrated the deterministic generation of entangled photon states using a single semiconductor quantum dot, and could thereby outperform fundamental sensitivity boundaries, unattainable with classical light.
Scientists have developed an artificial synapse capable of simulating a fundamental function of our nervous system - the release of inhibitory and stimulatory signals from the same 'pre-synaptic' terminal.
Researchers have found a way to create and clean tiny mechanical sensors in a scalable manner. They created these sensors by suspending a two-dimensional sheet of hexagonal boron nitride over small holes in a silicon substrate.
Superalloys are the wonder materials of metallurgy. By fine-tuning their composition, scientists can increase mechanical strength and improve resistance to corrosion and high-temperature shape changes.
A team of researchers has found a way to detect trace gases down to concentrations at the parts-per-quadrillion level using a new variation on the photoacoustic effect, a technique that measures the sound generated when light interacts with molecules.
