Neolithic agricultural revolution linked to climate-driven wildfires and soil erosion - new study finds

A new study reveals that the Neolithic Revolution in the southern Levant was triggered by catastrophic wildfires and climate-driven soil erosion, forcing early communities to adopt agriculture. Fertile soils formed in valley basins after hillslope degradation became hotspots for settlement and farming.

Female children may face greater emotional and immune challenges from prenatal stress, study finds

A new study found that prenatal stress alters the expression of tiny RNA molecules in newborn blood, particularly in female children, affecting key enzymes in the brain's stress-regulation system. This may explain why some children are more vulnerable to developmental or psychiatric challenges.

Eye test could predict postoperative delirium in older patients

Researchers found that a thicker preoperative macular layer in the right eye was associated with an increased risk of postoperative delirium. The study suggests that retinal imaging may serve as a non-invasive biomarker to identify individuals at risk, particularly after anesthesia and surgery.

Cellular pathways and treatment frontiers of achondroplasia

Achondroplasia stems from FGFR3 gain-of-function mutations disrupting skeletal development, leading to stunted growth, skeletal deformities, and joint complications. Emerging therapies target the FGFR3 pathway with biological drugs, small molecule inhibitors, gene-editing technologies, and downstream signaling compounds.

A new path in pancreatic cancer treatment: the therapeutic promise of GOT2

Researchers highlight GOT2 as a compelling therapeutic target for treating pancreatic cancer, exploiting its role in regulating cellular redox balance and energy production pathways. Early candidates like amino oxyacetate show promise in disrupting GOT2 activity, leading to cellular senescence and loss of proliferative capacity.

Pump-induced stimulated superradiant Smith-Purcell radiation with ultra-narrow linewidth

Scientists have created a compact device that enables ultra-narrow spectral linewidth of superradiant Smith-Purcell radiation, overcoming limitations in free electron accelerators. The device, called pump-induced stimulated S-SPR (PIS-SPR), uses a three-section system to pre-bunch electrons and emit radiation at a specific frequency.
