North Carolina State University researchers have demonstrated a new technique for creating ultrasound images. The new approach is substantially simpler than existing techniques and could significantly drive down technology costs.

“Conventional ultrasound devices have a receiver that detects ultrasonic waves and converts them into an electrical signal, which is then sent to a computer that processes the signal and converts it into an image,” says Xiaoning Jiang, co-corresponding author of a paper on the work and a Duncan Distinguished Professor of Mechanical...

In a mouse study, researchers have found that an antibody that targets the protein TREM2 empowers tumor-destroying immune cells and improves the effectiveness of cancer immunotherapy.

Immunotherapy has revolutionized cancer treatment by stimulating the patient’s own immune system to attack cancer cells, yielding remarkably quick and complete remission in some cases...

Cooled graphene mimics effect of enormous magnetic fields that would benefit electronics. Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature.

Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers...
