Scientists discovered rare flavoalkaloids in Cannabis leaves for the first time, along with dozens of other phenolic compounds that had never been reported in the plant. The findings suggest that Cannabis leaves, often discarded as waste, may contain a surprisingly rich source of potentially useful…
Un equipo de la Universidad Médica de Wrocław, en Polonia, halló que las dificultades para conciliar el sueño, los despertares frecuentes y la somnolencia diurna se asociaron con más días de cefalea al mes y menor bienestar

A major analysis suggests Phelan-McDermid syndrome, a genetic disorder closely linked to autism, may affect about 1 in 7,300 people and more than 45,000 Americans. Researchers warn that thousands of cases may remain hidden because genetic testing is often not performed, even as targeted treatments…
Researchers used CRISPR to remove CD33 from donor stem cells, potentially giving doctors a way to attack aggressive blood cancers without destroying the healthy cells patients need after a transplant. In a 30-patient trial, the edited cells successfully took hold and appeared to shield blood…
La nutricionista Adriana Hamer explicó en Infobae Al Amanecer cómo adaptar la alimentación durante estos procesos y qué aspectos individuales deben tenerse en cuenta
Los científicos investigan estos episodios en personas con Alzheimer y trastornos relacionados, aunque aún desconocen los mecanismos cerebrales que hacen posible el retorno temporal de capacidades cognitivas aparentemente perdidas
A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of cell death linked to iron buildup and oxidative…
Scientists discovered a surprising backup system that lets mammalian cells make the essential amino acid cysteine even when the pathways once considered indispensable are disabled. The same survival mechanism may help cancer cells resist treatment, raising the possibility that shutting it down could make tumors…
Nature Medicine, Published online: 25 September 2026; doi:10.1038/s41591-026-04684-0 Polygenic scores in the NHS: the debate is not primarily about the evidence
Después de 4 muertes relacionadas con el sarampión en Pensilvania, las autoridades sanitarias esperan que la gente se anime a vacunarse en privado.
Afrontar una situación como la vivida este miércoles en Madrid arrastra a estas personas a un 'duelo' profundo y a la pérdida del control total sobre sus vidas Y además: El Gobierno destina 45 millones para crear vivienda para estudiantes de Medicina y Enfermería
by Kanna Hayashi, Eric C. Sayre, Jennifer McDermid, Samona Marsh, Caitlin Shane, Michael-John Sheridan Milloy, P.O.W.E.R. , Thomas Kerr Background Housing is a key determinant of health. In response to increasingly visible homelessness amid a growing housing crisis, many jurisdictions in North America forcibly displace…
A 70-year-old leukemia drug is still revealing new secrets. Researchers found that removing a protein called NUDT5 protected cells from the drug, even though simply blocking the protein had little effect. The unexpected result points to a hidden cellular role that could help explain why…
A newly identified breakdown in communication between nerves and muscles could help explain why people lose strength as they age. Researchers were able to improve muscle strength in an animal model by targeting a key protein, raising hopes that some age-related weakness could eventually be…

A large study tracking more than 95,000 people suggests that how you sleep may be linked to your risk of developing dozens of diseases. People who spent more time in REM sleep had lower risks of 83 conditions, including dementia, heart failure, and Parkinson’s disease…
Children taking GLP-1 medications (such as Victoza, Saxenda, Trulicity, and Ozempic) for weight loss, prediabetes, or type 2 diabetes may face an overlooked risk: nutritional deficiencies. A new study found that nearly 1 in 6 young patients developed a diagnosed deficiency within a year of…

A U.S. Food and Drug Administration investigation resulted in a federal court order, dated Sept. 21, 2026, stopping a warehouse operator from distributing FDA-regulated products including food, drugs, medical devices, and cosmetics until it fixes its operations to meet federal legal requirements.

A major Swedish study of 3.7 million people has found that rare TORCH infections passed from a pregnant woman to the fetus are linked to much higher risks of autism and intellectual disability later in life. Children with a congenital TORCH infection were about three…

A topical drug that removes aging, damaged cells helped older mice heal skin wounds significantly faster. The treatment appeared to reactivate repair pathways involved in inflammation, collagen production, and new blood vessel growth.
A new experimental drug called CS18 may help break through cancer drug resistance by disabling several of the defenses tumors use to survive treatment. It strengthened existing therapies, restored drug sensitivity in resistant lung cancer cells, and slowed tumor growth in animal models.
BackgroundPost-acute COVID-19 syndrome (PACS) can cause persistent disability involving fatigue, post-exertional malaise, neurocognitive symptoms, and autonomic manifestations. A clinically overlapping condition has been reported following COVID-19 vaccination and termed post-acute COVID-19 vaccination syndrome (PACVS), but its underlying mechanisms remain poorly understood. We investigated whether immune…
BackgroundCancer-associated fibroblasts (CAF) are major regulators of the tumor microenvironment (TME), yet the pathways governing CAF function remain incompletely understood. Type 2 deiodinase (DIO2, D2), which converts thyroxine (T4) to the active thyroid hormone triiodothyronine (T3), has not been systematically investigated in CAF across different…
Disorders of consciousness (DoC) are characterised by marked reductions in cerebral glucose metabolism, but the specific cellular and neurochemical processes driving this impairment remain unclear. To elucidate these mechanisms, a multimodal imaging approach combining [18F]-fluorodeoxyglucose positron emission tomography (FDG-PET) and magnetic resonance spectroscopy (MRS) was…
Depression is one of the most prevalent mental health disorders globally. Social media content can reflect emotional states, offering real-time signals of depressive symptoms. This study aimed to develop a deep learning model to predict depression using Twitter/X data, and to characterize potential causes of…
ObjectivesTo estimate the prevalence of objective peripheral neuropathy, and to test whether self-reported use of personal protective equipment (PPE) is associated with lower neuropathy risk, among adults attending a community hospital in a Nigerian population exposed to both agrochemicals and mining. DesignClinic-based cross-sectional study (June-November…
ObjectiveThe Concise Health Risk Tracking (CHRT) assessment has utility in suicide risk prediction in adults and adolescents. Because multi-informant assessment is the gold standard in pediatric populations, a parent report version of the CHRT may enhance evaluation of youth suicide risk. We adapted the self-report…
Individuals with Down syndrome (DS) exhibit accelerated biological aging and unique patterns in disease prevalence. However, empirical characterizations of relative risk and age at onset of disease in this population are not common. Here we aimed to quantify the difference in risk and timing of…
