With hybrid work hardening from trend to new normal, correspondent Jon Wertheim looks at the crisis in commercial real estate, specifically in New York City's office sector. As occupancy rates have hit historic lows and interest rates have spiked, the value of office buildings is tanking. It's a growing problem nationwide, with more than a trillion dollars in commercial real estate loans set to expire in the next two years. Wertheim speaks with industry players about how they're staying afloat in a sector of the economy that's been rocked to its foundations. Correspondent Sharyn Alfonsi reports on a groundbreaking approach to brain surgery that could revolutionize the treatment of Alzheimer’s disease and drug addiction without any incisions. Alfonsi follows neuroscience pioneer Dr. Ali Rezai for more than a year as he tests experimental procedures at the Rockefeller Neuroscience Institute in Morgantown, West Virginia. The results of Rezai’s clinical trials are changing the lives of his patients and may offer hope to others suffering from brain disorders.
