One molecule, two effects: A new drug concept to treat obesity and type 2 diabetes

A new approach for treating obesity and type 2 diabetes has been developed using a hybrid molecule that targets specific cells. The treatment combines the well-known GLP-1/GIP signalling pathway with an additional metabolic modulator, delivering improved blood-glucose values and weight loss.

Researchers demonstrate new integrated plasma regime

A new integrated plasma regime has been demonstrated in a metal-wall environment, achieving partial divertor detachment, an ELM-free H-mode, and high pedestal performance. This regime was sustained on a minute-scale and offers a potential solution to managing extreme heat loads on divertor plates while maintaining plasma stability.

Single-pulse lithography of amorphous photonic architectures inside all-inorganic dielectric crystals

Researchers have developed a single-pulse anisotropic amorphization lithography technique to create regular sheet-like structures inside all-inorganic dielectric crystals. The method uses ultrafast laser pulses to induce controlled phase transitions, enabling high-purity amorphization and precise control over structure formation.

After Rome: genomic insights from southern Germany on the formation of Central European societies

A study of ancient genomes found that individuals from northern Europe were buried in cemeteries in southern Germany during the late Roman period, suggesting regional mobility. The research team reconstructed family relationships and showed how new structures emerged as people adopted Roman ways of life.
