A US cohort study of 5,520 children found no overall association between prenatal exposure to fluoride in public drinking water and internalizing or externalizing behavioral problems across the primary analyses. Exploratory analyses identified some associations with externalizing problems at higher fluoride concentrations and in certain subgroups, but the researchers said these findings require further investigation.

Subcutaneous administration of tarlatamab was well tolerated and demonstrated preliminary antitumor activity in patients with previously treated extensive-stage small cell lung cancer (ES-SCLC), according to findings from the phase 1b DeLLphi-308 study presented at the International Association for the Study of Lung Cancer (IASLC) 2026 World Conference on Lung Cancer (WCLC).

Extended-interval dosing regimens of tarlatamab demonstrated efficacy, safety and pharmacokinetic profiles generally consistent with the established every-two-week regimen in patients with previously treated for small cell lung cancer (SCLC), according to results from the randomized Phase 2 DeLLphi-309 study presented at the International Association for the Study of Lung Cancer (IASLC) 2026 World Conference on Lung Cancer (WCLC).

Adding local consolidative therapy (LCT) after induction treatment with nivolumab plus ipilimumab did not improve overall survival or progression-free survival in patients with metastatic non-small cell lung cancer (NSCLC), including those with oligometastatic disease, according to results presented at the International Association for the Study of Lung Cancer (IASLC) 2026 World Conference on Lung Cancer (WCLC).

Patients with resectable stage II–IIIB non-small cell lung cancer (NSCLC) treated with perioperative atezolizumab plus platinum-based chemotherapy experienced a median event-free survival of 62.8 months compared with 34.9 months for patients receiving chemotherapy alone, according to final results from the Phase 3 IMpower030 trial.

An investigational EGFR x HER3 antibody-drug conjugate demonstrated promising efficacy with a tolerable safety profile in patients with previously treated EGFR-mutated non-small cell lung cancer (NSCLC), supporting selection of the 2.5 mg/kg dose for evaluation in the global Phase 3 IZABRIGHT-Lung01 registrational study.

The investigational combination of pumitamig and elfetabart drozuntecan (elfe-D) demonstrated a manageable safety profile and encouraging early antitumor activity in patients with small cell lung cancer (SCLC), according to first clinical data from the ongoing Phase 1b/2 BNT324-01 trial presented at the International Association for the Study of Lung Cancer (IASLC) 2026 World Conference on Lung Cancer (WCLC).

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows that, in people living with diabetes (type 1 or 2) using data from continuous glucose monitoring (CGM) devices paired with daily quality-of-life ratings, days with more widely fluctuating glucose readings (while still within safe limits) are followed by days with a better quality life compared to days with more stricter control– suggesting the burden of that stricter control could be preventing those individuals with stricter control from enjoying various activities.

Scientists identified a new vision condition linked to a gene already connected to a different vision-loss disease. While the previously identified disease causes loss of central vision, the new condition affects peripheral and night vision.

What makes the brain fall asleep? For nearly a century, scientists have looked to structures deep within the brain for the answer.

Neurons receive thousands of signals via tree-like extensions called dendrites. Until now, these dendrites were thought to be relatively smooth cables that conduct electrical signals to the cell body.

A research team at Huntsman Cancer Institute at the University of Utah (the U) has found that obesity prevents a biological process that kills cancerous cells, revealing a possible reason why obesity is a risk factor for breast cancer.

Why do genetic variants that increase the risk of autoimmune disease remain so common in the population?

Researchers at the University of Oslo have mapped which parts of our DNA carry the inherited differences behind complex traits and disorders.

Tooth enamel looks simple from the outside and consists of a hard, smooth surface built to withstand years of wear.

Influenza remains a major global health challenge as continual antigenic drift can limit the breadth and durability of vaccine-induced antibody responses, requiring frequent vaccine updates.

Risk factors for cardiovascular-kidney-metabolic disease, a health condition made up of heart disease, kidney disease, diabetes, and obesity, can be identified in children as young as 8, UTHealth Houston researchers discovered.

Iron is an essential micronutrient, but excess iron can damage cells and increase cancer risk. While many cells die from iron-induced oxidative stress, a subset survives and may become cancerous.

According to a Finnish study, people sleep slightly longer when they work from home. However, they also sit more and are less physically active than on days when they work in the office.

Early and consistently managed treatment can have a decisive impact on the course of rheumatoid arthritis and prevent permanent joint damage.
