Heavy caffeine users and deeper sleep; wonders of microscopic life; preparing for life after an Alzheimer’s diagnosis; plus other stories with Vanderbilt Health sources
Beth Malow, MD, Professor of Neurology and Pediatrics in the Vanderbilt Sleep Division, was quoted in Women’s Health about a surprising study from the Journal of Psychopharmacology indicating that heavy caffeine users get deeper non-rapid-eye-movement sleep, even while sleeping less time. The New York Times quoted Dylan Burnette, PhD, Associate Professor of Cell and Developmental Biology, in a story (with videos) about the wonders of the microscopic life all around us. William Schaffner, MD, Professor of Preventive Medicine, was quoted by several news outlets about public health issues, including: Prevention (rabies vaccinations); Healthline (update on the Cyclospora outbreak); Prevention again (hundreds now sickened in measles outbreak); and AARP (“How do we know vaccines are safe?” video interview and transcript). Science posted a story about a new NIH research center on vaccine harms. The piece quotes Kathryn Edwards, MD, Professor of Pediatrics, Emerita. Lealani Mae Acosta, MD, MPH, Associate Professor of Neurology, was quoted in an Everyday Health story about how a person, after a diagnosis of Alzheimer’s disease, can enrich their life and prepare for the future. Amalia Peterson, MD, Assistant Professor of Neurology, was quoted by Everyday Health in a piece about common medications linked to lower dementia risk.
Coffee may help the body fight stress and aging through a hidden cellular switch
Scientists may have uncovered one reason coffee is repeatedly associated with healthier aging and lower disease risk. Compounds in coffee appear to activate NR4A1, a receptor that helps protect cells from stress, inflammation, and damage. These protective effects disappeared when the receptor was removed, strengthening the connection. Surprisingly, plant-based compounds such as caffeic acid seemed far more active than caffeine itself.

Caffeine reversed memory problems caused by sleep deprivation
Scientists discovered that sleep deprivation damages a key brain circuit responsible for social memory, making it harder to recognize familiar individuals. In laboratory studies, caffeine restored communication between neurons in this pathway and reversed the memory deficits caused by lost sleep. The effect was remarkably targeted, helping the impaired circuit recover without overstimulating normal brain function.

What caffeine does to ants could change pest control
Caffeine doesn’t just perk up humans—it can sharpen ants’ minds too. Invasive Argentine ants given caffeinated sugar learned to find food much more efficiently, taking straighter paths and reducing travel time by up to 38%. They weren’t faster, just more focused, indicating improved learning. This unexpected effect could make pest control baits far more effective.

Your morning coffee could one day help fight cancer
Scientists at Texas A&M are turning an everyday pick-me-up into a high-tech medical switch. By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance — and then activated simply by consuming a small dose of caffeine from coffee, chocolate, or soda. The approach, known as chemogenetics, lets scientists precisely turn gene-editing activity on and off inside targeted cells, including powerful immune T cells that can fight cancer.

Coffee at night may increase risky behavior, especially in women
Drinking coffee at night might come with an unexpected downside: increased impulsivity. In a new study, fruit flies given caffeine after dark behaved more recklessly, ignoring signals that normally make them stop. Daytime caffeine didn’t have the same effect, pointing to a strong link between timing and behavior. Even more striking, females were far more sensitive than males.

Coffee may protect your heart but energy drinks could harm it
For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is generally safe and may even be linked to lower risks of heart disease, stroke, heart failure, and Type 2 diabetes. But the source matters: highly concentrated energy drinks and shots can sharply raise blood pressure and trigger irregular heart rhythms.

50 children in our area hit by cars every year; toxic pond water in Centennial Park; ‘gas station heroin’; plus other stories with Vanderbilt Health sources
In a news report following a Murfreesboro child who was killed by an automobile, reporter Amber Jayanth from WSMV Channel 4 News cited statistics gathered at Monroe Carell Jr. Children’s Hospital at Vanderbilt about pediatric pedestrian injuries. Trauma registry data from Monroe Carell indicates that about 50 children per year on average are treated after being hit by a car. William Schaffner, MD, Professor of Preventive Medicine, was quoted by several news outlets about public health issues, including: CNN (mRNA flu vaccine); ABC News and the American Journal of Managed Care (Pennsylvania measles outbreak); News Channel 5 (blue-green algae in the pond at Centennial Park, which can release toxins that make people and pets sick). WSMV Channel 4 News interviewed Saumya Aujla, MD, Assistant Professor of Clinical Physical Medicine and Rehabilitation, about the health risks of kratom, sometimes called “gas station heroin,” and why Tennessee banned the drug. WTVF News Channel 5 interviewed Brianna Smith, MD, Assistant Professor of Pediatrics, Hematology/Oncology at Monroe Carell Jr. Children’s Hospital at Vanderbilt for a piece on Childhood Cancer Awareness Month. Prevention interviewed Mitchell Gigandet, MD, Assistant Professor in the Neuro-Sleep Division, for a story about MDPI research on caffeine that used EEG imaging to see how the drug impacts sleep.

The Wall Street Journal reporter Laura Landro interviewed Joseph Schlesinger, MD, Professor of Anesthesiology Critical Care Medicine, for a story about ICU alarms keeping patients from getting sleep and creating alarm fatigue for nurses. Billboard reporter Melinda Newman interviewed country star Dasha about her upcoming vocal surgery at Vanderbilt Health. The story was picked up by numerous print and radio outlets including People.
Coffee doesn’t have to keep you awake to disrupt your sleep
Caffeine may make sleep less restorative even when you fall asleep normally and stay in bed for eight hours, with EEG recordings revealing fewer of the slow brain waves associated with deep sleep. Individual sensitivity varies dramatically, meaning even caffeine consumed earlier in the day could affect nighttime recovery for some people.

A huge long-term study found that drinking two to three cups of coffee a day was linked to a much lower risk of dementia, especially before age 75. Researchers say caffeine may help keep brain cells active while reducing inflammation and harmful plaque buildup associated with Alzheimer’s disease. But more coffee wasn’t better — the protective effect appeared to level off after moderate intake.
