Chicago Woman's Five-Year Symptom Journey Leads to Rare Brain Tumor Diagnosis
Melony Aponte, 26, was diagnosed with a 4.5-centimeter acoustic neuroma after five years of symptoms she attributed to stress, COVID-19, and aging. The rare, noncancerous tumor—affecting roughly one in 100,000 people—had grown large enough to compress her hearing and balance nerve before it was identified via MRI in March 2025. Her case highlights how acoustic neuroma symptoms can mimic common conditions, potentially delaying diagnosis for years.
Study Finds Aging Shifts Walking Strategy Toward Stability at the Cost of Efficiency
A new study from Flinders University and the University of Canberra found that as people age, their bodies adopt a 'safety-first' walking pattern that prioritizes balance over efficient movement. Researchers analyzed gait data from 107 healthy adults aged 26 to 86, identifying increased ankle muscle co-contraction and reduced push-off power as key age-related changes. The findings suggest that fall prevention programs should target balance and coordination, not just muscle strength.
Tick Populations Surge in Urban Areas Across Northeast
Experts across the northeastern United States and Canada are warning of an unusually early and widespread tick season, with disease-carrying ticks increasingly found in urban parks and green spaces. Lyme disease cases in Canada reached a record 7,105 in 2025, up from 5,809 the previous year, while U.S. cities including Philadelphia, Pittsburgh, Washington D.C., and New York are reporting rising tick activity. The expansion poses a public health challenge because urban residents are less likely to take tick-bite precautions than those in rural areas.
Study suggests eating 5 fruits and vegetables daily may not provide enough heart-protective compounds
A new study published in the journal Food & Function found that fewer than 25% of people who met standard fruit and vegetable dietary guidelines consumed enough flavanols — plant compounds linked to cardiovascular benefits — to reach the 500mg daily threshold associated with a 27% reduction in cardiovascular disease mortality. The research, involving more than 30,000 adults in the U.S. and U.K. and conducted by scientists from the University of Reading, Harvard Medical School, UC Davis, and Mars, Inc., found that the specific types of fruits and vegetables consumed matter more than total quantity. The findings suggest that current dietary guidelines may need to be refined to specify flavanol-rich foods such as blueberries, blackberries, plums, broad beans, and green tea.
Stanford researchers develop treatment that restores cartilage and reverses arthritis in mice and human tissue
Stanford Medicine researchers have shown that blocking a protein called 15-PGDH can regrow lost knee cartilage in older mice, prevent post-injury arthritis, and stimulate new cartilage production in human tissue samples. The protein is a "gerozyme" that increases with age and suppresses tissue regeneration by breaking down prostaglandin E2, a molecule critical for cellular repair. The findings, published in Science, raise the possibility of injectable or oral treatments that could address the root cause of osteoarthritis rather than merely managing its symptoms.
New blood test can detect thousands of genetic conditions in pregnancy without invasive procedures
Scientists have developed a maternal blood test called non-invasive fetal sequencing (NIFS) that can detect thousands of serious genetic conditions in a developing fetus with 95–99% accuracy. The test analyzes fragments of fetal DNA circulating in the mother's bloodstream and was validated on 565 pregnancies, identifying variants across nearly 23,000 genes. It could reduce reliance on riskier invasive procedures like amniocentesis, though experts warn that broad screening use could generate anxiety-inducing results of uncertain significance.
New WHO-backed research outlines strategies to prevent postpartum hemorrhage deaths
A three-part series published in The Lancet, co-authored by WHO physicians, identifies postpartum hemorrhage as the leading cause of maternal death and proposes a comprehensive set of interventions to address it. The condition affects 27 million women annually and kills 43,000, with mortality rates more than 200 times higher in low-resource countries than in wealthy ones. Researchers say adopting existing tools — including calibrated blood-collection drapes, standardized treatment protocols, and simulation-based team training — could reduce deaths by more than 95%.
California Resident Dies from Leptospirosis After 200 Rats Found in RV Near Berkeley Homeless Camp
A Berkeley, California resident died in May from leptospirosis, a bacterial disease spread through infected animal urine, after living in an RV where they had been trapping, feeding, and breeding wild rats. City Manager Paul Buddenhagen confirmed the death in a June 10 memo to the City Council, noting that nearly 200 rats were removed from the severely infested vehicle before it was towed and destroyed. The case marks Berkeley's first known human leptospirosis death in more than a decade and has prompted public health officials to broaden their outreach beyond a previously established geographic warning zone.
Dr. Joseph Mercola Reverses Long-Held Opposition to Vitamin K Shots for Newborns
Dr. Joseph Mercola, a prominent alternative medicine figure who spent over a decade warning parents against newborn vitamin K shots, has publicly reversed his position, now stating 'the data is clear: vitamin K saves lives.' His reversal came days after ProPublica contacted him while preparing a report on infant deaths linked to parents refusing the shot. The shift is significant because Mercola's earlier writings were widely cited by vaccine-skeptical parents, and refusal rates for the shot have risen 77% between 2017 and 2024.
Autistic Children Receiving Unapproved Stem Cell Injections Backed by Health Secretary RFK Jr
Clinics in Florida, Texas, and other states are selling unproven stem cell infusions for autistic children at costs up to $20,000 per treatment, with no scientific evidence of efficacy. Health Secretary Robert F. Kennedy Jr. has publicly endorsed the practice at industry summits and appointed a leading advocate to a federal autism research committee. The FDA warns that such treatments offered outside approved clinical trials are likely illegal and have been linked to serious complications including blindness and tumor formation.
Trump Administration Releases Final Medicaid Work Requirements Rules for 2027 Implementation
The Centers for Medicare & Medicaid Services released final rules on June 1 implementing Medicaid work requirements, mandating that certain enrollees document 80 hours per month of qualifying activities such as employment, education, or volunteering. The requirements stem from last year's budget reconciliation law and will apply to roughly 18.5 million Medicaid expansion enrollees across 42 states and Washington D.C., with most states beginning enforcement on January 1, 2027. The rules will determine whether millions of low-income adults retain health coverage, with advocates warning that administrative burdens could cause eligible people to lose benefits.
WHO warns of 'blind spots' in Congo Ebola outbreak as cases spread to displacement camps
A WHO epidemiologist warned Friday that surveillance gaps mean the Ebola outbreak in the Democratic Republic of Congo is likely far larger than the officially reported 676 confirmed cases and 136 deaths. The outbreak, caused by the rare Bundibugyo strain with no approved treatment or vaccine, has spread to three new health zones and neighboring Uganda, while two deaths have been confirmed in a 30,000-person displacement camp. The situation is alarming because overcrowded refugee camps, a shortage of only 250 isolation beds across three provinces, and high population mobility could accelerate transmission well beyond current detection capacity.
