MR-Guided Adaptive SBRT Tied to Reduced Side Effects in Prostate Cancer
Magnetic resonance (MR)‐guided adaptive stereotactic body radiotherapy (SBRT) for prostate cancer was associated with significantly lower rates of acute genitourinary and gastrointestinal toxicities compared with CT-guided non-adaptive SBRT, according to a systematic review and meta-analysis. Across 29 prospective studies involving over 2,500 patients, the risk of short‐term genitourinary side effects was reduced by 44% with […]
Can obesity and stress influence appetite? New study shows it’s all in your head
In a series of experiments using functional magnetic resonance imaging (fMRI) to measure brain activity across networks in the brain, Johns Hopkins Medicine researchers looked at how stress might increase appetite in obese and lean adults. The researchers found that stress impacts the brain’s responses to food, and that both lean and obese adults react […]
Quantum sensor can detect electromagnetic signals of any frequency: Engineers expand the capabilities of these ultrasensitive nanoscale detectors, with potential uses for quantum computing and biological sensing.
Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only been capable of detecting a few specific frequencies of these fields, limiting their usefulness. Now, researchers at MIT have developed a method to enable such sensors to […]

Scientists observe a new type of topological defect in chiral magnets
“Topological defects” are formed when the symmetry of a magnetic material is disrupted. Domain walls (DWs) are a type of topological defect that separates regions of different magnetic orientations. A widely studied phenomenon, the manipulation of these defects has potential applications in high-performance memory storage devices, energy processing devices, and quantum computing. Recently, the possibility […]
