New Book Argues Pregnancy Triggers a 'Second Puberty' in the Brain, Not 'Mommy Brain'
Neuroscientist Susana Carmona’s new book, 'A Mother’s Brain,' argues that pregnancy causes profound, lasting changes to the maternal brain, a process she terms 'matrescence.' This phenomenon involves significant neuroplasticity and hormonal shifts that reshape the brain similarly to puberty, rather than causing the cognitive decline often labeled 'mommy brain.'

New Mouse Study Links Semaglutide to Slower Aging and Longer Lifespan
A new study in Nature demonstrates that semaglutide, a GLP-1 receptor agonist, slows aging and extends lifespan in female mice. While these drugs are approved for diabetes and obesity, emerging evidence suggests they offer broader therapeutic benefits beyond weight loss and glucose control, though the specific mechanisms remain unclear.
Study: Creatine Boosts Muscle Mass in Sedentary Adults
A 12-week study from Texas A&M University indicates that daily creatine supplementation can increase lean muscle mass and strength in sedentary adults aged 45-65, even without structured exercise. While exercise combined with creatine yields greater results, the supplement alone showed significant benefits for muscle preservation and cognitive function in older adults.
AstraZeneca bets $2B on Summit’s dual-target cancer drug to power next-gen therapies
AstraZeneca has invested $2 billion in Summit Therapeutics to develop combination cancer therapies using Summit’s lead drug, ivonescimab. CEO Pascal Soriot described the bispecific antibody as the 'next generation' of cancer care, noting its ability to outperform Merck’s Keytruda in lung cancer trials. The deal grants AstraZeneca a 12% stake but leaves commercial rights with Summit. Concurrently, AstraZeneca opened a $1 billion research facility in Cambridge, Massachusetts, utilizing AI and robotics to accelerate drug discovery for obesity, cancer, and rare diseases.

Health Influencer Matt Roeske Promotes Radioactive Water to 500,000 Followers
Holistic health influencer Matt Roeske has drawn widespread criticism for posting a video in which he drinks from a 'Revigator,' a 1920s-era ceramic jug containing radioactive materials. Roeske, who has over 500,000 Instagram followers, claims he has consumed this water for 250 days, asserting that the radioactive content is harmless and cures various ailments. The Revigator contains carnotite, a uranium-rich rock, along with arsenic, lead, and vanadium. Roeske attributes the historical ban on such products to a conspiracy by the 'Rothschild medical system' to suppress profitable cures. This incident highlights the dangers of unregulated wellness advice on social media, particularly given the historical precedent of Eben Byers, a steel magnate who died from severe radium poisoning after consuming similar products. The FDA and FTC banned these items in the 1930s after they caused fatal health complications, including jawbone cancer and skull deterioration.
Arizona Confirms First Fatal Pneumonic Plague Case Since 2007 Linked to Cat Exposure
A young man in Coconino County, Arizona, died from pneumonic plague in July 2025, marking the state's first such fatality since 2007. The CDC report details how rapid identification of exposed individuals for prophylaxis occurred before final lab confirmation, highlighting the importance of clinical suspicion in endemic areas.

Endpoints News Highlights 20 Women Driving Change in Biopharma
Endpoints News has released its eighth annual special report recognizing 20 women who are significantly influencing the biopharmaceutical industry. The honorees span diverse sectors, including oncology and rare disease research. This initiative is part of a broader effort that has recognized over 160 women across various biopharma sectors since the program's inception.
Prolonged Fasting Triggers System-Wide Molecular Shifts After Three Days
A 2024 study in Nature Metabolism reveals that seven days of water-only fasting causes coordinated biological changes across multiple organs, with significant molecular shifts emerging only after approximately three days of calorie restriction.
Fat Cells May Retain a 'Memory' of Obesity, Driving Rapid Weight Regain
New research suggests that fat cells retain an epigenetic 'memory' of obesity, keeping hunger hormones elevated even after weight loss. This biological mechanism may explain why patients regain weight quickly after stopping GLP-1 medications, highlighting the need for long-term metabolic management rather than short-term fixes.
New Data Suggests Glucosamine May Accelerate Dementia in Early Cognitive Decline
A new study published in Nature Metabolism indicates that glucosamine, a widely used joint supplement, is associated with a 25% higher risk of progression from mild cognitive impairment to dementia. Researchers at the University of Florida found that the supplement may exacerbate abnormal sugar-tagging processes in the brain, though causality remains unproven.

Clean Label Project study finds lead and heavy metals in 99% of top cat food brands
A new investigation by the nonprofit Clean Label Project tested 100 top-selling cat foods from 62 brands and found toxic contaminants in nearly all samples. Lead was detected in 99% of the products, while cadmium and arsenic appeared in 96% and 94% respectively. The study also identified toxic plastic chemicals and the herbicide glyphosate across wet, dry, and freeze-dried varieties. Fish-based foods showed higher levels of mercury and cadmium, whereas chicken-based options had higher rates of lead and herbicides. Experts warn that chronic exposure to these substances may accumulate in cats over time, potentially contributing to kidney disease, though the pet food industry maintains that current safety protocols ensure product safety.
