El nuevo monstruo naval de China tiene una misión extraña: hundirse a medias antes de ponerse a trabajar

Cuando pensamos en un buque grúa, lo lógico es imaginar una mole de acero levantando piezas imposibles desde la superficie. El Sihang Yongsheng obliga a cambiar un poco esa imagen: cuando la operación lo requiere, puede aprovechar su diseño semisumergible para hundirse a medias y trabajar de otra manera. Ahí está lo más llamativo del nuevo gran buque de ingeniería naval entregado en China, no tanto en que sea grande, sino en la forma en que combina transporte pesado y elevación sobre el agua. China no llega a este punto desde cero. En las últimas décadas ha convertido varias de sus…

[Comment] A novel unimolecular GLP1 and amylin receptor agonist for glucose and weight control

The therapeutic landscape of type 2 diabetes and obesity has evolved from single-hormone incretin modulation towards multireceptor metabolic engineering. Amylin is cosecreted with insulin from pancreatic β cells in response to food intake and acts on amylin receptors distributed across the brain, pancreas, adipose tissue, and gastrointestinal tract to regulate appetite, delay gastric emptying, and decrease glucagon secretion, providing multisite integrative control of energy balance.1,2 Notably, amylin receptors are heterodimeric complexes composed of a calcitonin receptor core and receptor…
