The Perimenopause Startup Boom: Telehealth, Hormones, and a New Health Frontier
WIRED examines a rapid, venture-backed surge in hormone therapy for perimenopause driven by telehealth platforms (Midi, Winona, Alloy, Evernow) and policy shifts after FDA warnings were lifted, fueling broad marketing of a wide range of symptoms as solvable by hormones. The piece juxtaposes patient‑level relief with warnings about overdiagnosis, safety risks, and supply constraints, arguing the trend reflects a broader move toward platform‑based, privatized women’s health care.

Study ties xylitol to higher risk of heart attack and stroke
A European Society of Cardiology study found higher blood levels of the artificial sweetener xylitol are associated with increased risks of heart attack and stroke in two large cohorts (Canada and Europe), with up to 57% higher risk in Canada and 18% in Europe after adjusting for common risk factors; researchers urge more studies as xylitol is common in foods and dental products.
Hidden Tomato Compound Could Help Protect the Liver
Tufts University researchers found that phytoene, a colorless compound in tomatoes, reduced fatty liver severity in mice fed a high-sugar diet, suggesting whole tomato products may protect the liver beyond lycopene. Phytoene appears to promote liver fat burning through metabolic pathways and may require conversion into smaller metabolites to be effective. Genetic differences in processing enzymes and sex-based differences in liver accumulation could influence its benefits. If future studies in humans confirm these findings, increasing phytoene-rich fruits and vegetables could be a dietary strategy to prevent or slow metabolic liver disease.
Tailored mRNA cancer vaccines show promise against melanoma and beyond
Personalized mRNA cancer vaccines from Moderna and Merck are showing promising late-stage results in cancers such as melanoma, pancreatic and brain tumors by training the immune system to recognize tumor-specific mutations. When combined with immunotherapy, these vaccines have reduced cancer recurrence and extended remission in some patients. More than 120 trials since the early 2000s illustrate ongoing progress and optimization of targets and combinations, though bringing an mRNA cancer vaccine to the public could take 10–15 years amid funding shifts.
Move, Munch, Mind-Wander: Outsmart the Brain Cliff in Midlife
Dr. Swan reframes cognitive decline as cognitive change and explains the brain’s scaffolding—the neural networks that preserve thinking—can be strengthened in midlife through regular exercise, an anti-inflammatory diet, stress management, and ongoing learning and social engagement. Mind-wandering and mental time travel may support this scaffolding, while retirement without active engagement can hasten decline; it’s never too late to start protecting your brain.
Ackman backs experimental eye-cell therapy to restore his daughter's sight
In a first-of-its-kind approach, scientists transferred cell parts from the leg of Bill Ackman’s 26-year-old daughter to her eyes to help restore her vision after a brain hemorrhage left her unable to move, speak, or see, with the billionaire backing this daring treatment as a potential breakthrough in vision restoration.
Xylitol Under Scrutiny: Healthier Sweetener Alternatives for a Heart-Healthy Diet
Observational data link higher blood levels of xylitol with an increased risk of major cardiovascular events over six years, though causation isn’t proven; researchers warn against relying on sugar substitutes and advise limiting added sugars while choosing natural options such as whole fruit, unsweetened applesauce, monk fruit, stevia, and dates as healthier alternatives for heart health.
Late dinners and your heart health: timing matters after 9 PM
A Hindustan Times health article cites a Fortis Hospital cardiologist who says eating dinner after 9 PM is linked to higher cerebrovascular disease risk, based on a large observational study. The piece explains the circadian clock regulates metabolism and that late or irregular meals can disrupt blood sugar and hormonal balance. While not proving causation, it suggests earlier dinners may help support heart health and advises readers to consult their doctor for personal guidance.
Glioblastoma Achilles heel spotted, hints at stronger therapies
In preclinical models, blocking the SET protein reactivates the tumor-suppressing enzyme PP2A, reducing glioblastoma growth and making cancer cells more sensitive to radiation, offering a potential way to enhance standard therapies; human trials are needed to assess safety and efficacy.
Florida reports 400-plus Cyclospora cases tied to iceberg lettuce recall
More than 400 Floridians have been diagnosed with Cyclospora infections as health officials monitor an outbreak linked to recalled iceberg lettuce. The FDA says all recalled lettuce linked to the outbreak has been removed from shelves, while the CDC notes Cyclospora infections are more common in warmer months. Symptoms can include diarrhea, stomach cramps, nausea, fatigue and loss of appetite. Health officials urge consumers to follow food-safety guidance and check for recalled products.
Tyrosine Linked to Shorter Lifespan in Men, Study Finds
A UK Biobank analysis of over 270,000 participants found that higher body tyrosine levels are associated with shorter life expectancy in men, with no significant effect seen in women; phenylalanine showed no link after accounting for tyrosine. Using Mendelian randomization, researchers suggest a potentially causal, sex-specific relationship, possibly via insulin resistance and dopamine-related pathways. The study did not test tyrosine supplements, and more research is needed before any health recommendations; lowering tyrosine through diet remains speculative.
