Why this clinical trial is offering some young cancer patients hope Children’s National Hospital is poised to recruit patients for a new clinical trial that will take on an old, implacable foe: children’s solid tumors. Little progress has been made in 30 years.

A new clinical trial at Children's National Hospital in D.C. is taking aim at children's solid tumors an area with little progress to show for the last 30 years. My article in The Washington Post ran today: www.washingtonpost.com/science/2025...

The origins of hallucinations are traced in specialized brain cells Researchers used lasers to record and stimulate the activity of neurons in mice to learn how the brain processes and interprets optical illusions.

Why do optical illusions work? The culprit may be a group of neurons in the visual cortex that help us fill in missing information.

@markjohnpost.bsky.social for @washingtonpost.com dives into the science and how it could help demystify visual hallucinations: www.washingtonpost.com/science/2025...

Study finds mRNA coronavirus vaccines prolonged life of cancer patients A study found that covid-19 vaccines appeared to awaken the immune system in lung and skin cancer patients, helping them live longer than those not vaccinated.

Two months after HHS eliminates almost $500 million in funding for mRNA vaccine development, a new study finds evidence that the covid-19 vaccine almost doubled median survival length in some cancer patients. www.washingtonpost.com/science/2025...

Research on reversing Alzheimer’s reveals lithium as potential key Years of investigation by scientists at Harvard has revealed that lithium is deeply involved in Alzheimer’s disease, a finding that could lead to new treatments.

Harvard Medical School researchers have discovered that the depletion of lithium in the brain leads to much of the deterioration in Alzheimer's disease. In a mouse model, they were actually able to reverse the damage. Here's my story in The Post: www.washingtonpost.com/science/2025...
