Researchers identify the link between memory and appetite in the human brain to explain obesity
Disrupted connections between memory and appetite regulating brain circuits are directly proportional to body mass index (BMI), notably in patients who suffer from disordered or overeating that can lead to obesity, such as binge eating disorder (BED), according to new research from the Perelman School of Medicine at the University of Pennsylvania. Published today in […]
Benefits of Parathyroidectomy Run Far Deeper Than PTH Normalization
SEATTLE — Parathyroidectomy helped reverse disrupted levels of inflammatory cytokines and vitamin D metabolites in patients with primary hyperparathyroidism (PHPT), a researcher suggested here. After 50 patients, newly diagnosed with PHPT, underwent parathyroidectomy, serum intact parathyroid hormone (PTH) levels returned to the normal range within 3 months (115.6±38.9 to 42.6±24.5 pg/mL, P<0.001), said Xiangbing Wang […]
Dead star’s cannibalism of its planetary system is most far-reaching ever witnessed: White dwarf sheds light on the systemic chaos that occurs when a star dies
The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind — known as a white dwarf — is sucking in debris from both the system’s inner and outer reaches, UCLA astronomers and colleagues report today. This is the first case of cosmic cannibalism in which […]
The impact of COVID-19 on drug use — and how it contributes to overdose risk
The COVID-19 pandemic has disrupted the lives of people who use drugs in ways that hurt their mental health and changed drug use behaviors, increasing their risk for overdose, according to surveys and interviews with individuals in rural Illinois captured in a new study in Addiction Science and Clinical Practice. Drug overdoses have soared during […]
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 […]
