NIH – In its ongoing mission to shrink the federal government, the Trump administration has cut over a thousand jobs and billions in research grants from America's crown jewel of medical research – the National Institutes of Health. While other administrations have tried to downsize the NIH before, leaked Trump administration documents show plans to reduce the NIH budget by more than 40%, sending shockwaves throughout the scientific community. Correspondent Sharyn Alfonsi sits down with the former director of the NIH, Dr. Francis Collins, as well as with a researcher and an NIH insider who all say these measures could jeopardize the health of Americans for generations to come. Ashley Velie is the producer.

Evidence – Evidence has emerged that could change our understanding of the 9/11 terrorist attacks more than two decades ago. A 60 MINUTES investigation found that crucial information, initially turned over to the FBI shortly after the attacks, was never shared with the bureau's own field agents or senior intelligence officials. Correspondent Cecilia Vega reports on this evidence, which has come to light amid a lawsuit against the Saudi government filed by families of the nearly 3,000 victims and includes a video of a Saudi national filming the U.S. Capitol, thought to be al-Qaeda's fourth target. Richard Bonin and Mirella Brussani are the producers.

The Land of Declining Sons – The world's population may have recently surpassed 8 billion, but this is a misleading figure. Growth is unevenly distributed, and many countries are experiencing a decline in population – in some cases, steeply. Consider Japan. The country with the fourth-largest economy is now facing a rapidly declining birth rate and a population projected to shrink in half by this century's end. Correspondent Jon Wertheim reports from Japan, examining how these demographic changes affect the country and its culture. Jacqueline Williams is the producer.

Fraud – Correspondent Cecilia Vega reports on rampant fraud in government programs like unemployment, food stamps, disaster aid and more. With few safeguards at state and federal levels, taxpayers are falling victim to complex schemes carried out by scammers, hackers and transnational criminal organizations, costing the government hundreds of billions of dollars each year. Ayesha Siddiqi and Kit Ramgopal are the producers.

To Walk Again – For people who've suffered traumatic spinal cord injuries that have caused paralysis, positive news has been scarce. However, as correspondent Anderson Cooper discovers, innovative technology now in an early clinical trial is allowing participants to stand up and walk or move their arms – by thinking about it. Cooper reports from the NeuroRestore research lab in Lausanne, Switzerland, where he meets the team leading this groundbreaking research and hears the stories of patients enrolled in the trial. Nichole Marks is the producer.

Jamie Lee Curtis – Jamie Lee Curtis has been making movies for almost 50 years. Not surprising for a child born into Hollywood royalty. But to hear her tell it, leaving school as a teenager, only to graduate into an A-list movie star before she was 30, was never the plan. Correspondent Sharyn Alfonsi talks with Curtis in Los Angeles about her long career in Tinseltown and about her recent wave of award-winning performances that came to her in her 60's. Michael Karzis is the producer.
