Artist’s depiction of ultrasound waves destroying a cancer cell while leaving healthy cells intact. Credit: California Institute of Technology A new technique could offer a targeted approach to fighting cancer: low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed. Ultrasound waves—sound waves with […]

Unlike what we commonly refer to as ‘genes’, phantom genes or ‘Long noncoding RNA’ (LncRNAs) do not lead to the production of proteins that our cells, and thus our entire bodies are made of. Previously, it was believed that LncRNAs served no major purpose in cells, but new research now shows […]
