Moldovan police conducted 30 raids on homes and currency exchange offices linked to pro-Russian parties, seizing approximately 3 million lei in various currencies. The operations aim to combat illegal political financing and Russian interference in Moldova's political system.

Italian artist Maurizio Cattelan unveils "Sunday," a 17-foot-tall, 68-foot-wide gold wall pockmarked with over 20,000 rounds of ammunition at the Gagosian gallery in New York. The installation, which has generated significant buzz, serves as a thought-provoking commentary on modern society.

Isaiah Trammell, a 19-year-old autistic man, died in custody at the Montgomery County Jail in Ohio after being ignored by officers despite begging for his medication. Surveillance videos showed Trammell's desperate pleas for help, which were met with taunts and threats from nine guards.

Pope Francis has recognized a second miracle attributed to Carlo Acutis, a 15-year-old Italian boy who died in 2006, paving the way for his canonization. The canonization ceremony for Carlo Acutis is expected to take place in Rome, with the date to be announced in June.

Russian FSB dismantles Ukrainian agent network in Sevastopol, Crimea, seizing 5.5 kg of British-made explosives and detaining five agents. The agents, linked to Ukraine's SBU, were planning terrorist attacks and sabotage in the region.

The Shanghai Cooperation Organization (SCO) is set to welcome Belarus as a full member during its upcoming summit in Astana, Kazakhstan. Russia has also conditionally expressed support for Afghanistan's candidacy to join the SCO, contingent upon the country's economic stability.

This study conducts a comprehensive analysis and comparison of Bombyx mori cuticles across different developmental stages, ranging from larval to adult, utilizing advanced solid-state NMR techniques. The primary objective is to elucidate the underlying reasons for the contrasting hardness of adult cuticles and softness of larval cuticles. Notably, PXRD analysis reveals a prominent broad peak at 19.34°, indicating the predominantly amorphous nature of both larval and adult cuticles. Analysis of 13C CP-MAS SSNMR spectra highlights an elevated proportion of phenoxy carbon in adult cuticles (6.77%) compared to larval cuticles (1.24%). Furthermore, a distinctive resonance line at 144 ppm is exclusively observed in adult cuticles, due to catechols, suggesting potential biochemical pathway variations during development. Significant variations in the primary components of 13C chemical shift anisotropy (CSA) tensors for aliphatic carbons of amino acids, catechols, and lipids between adult and larval cuticles indicate alterations in electronic environments. Additionally, the shorter spin–lattice relaxation time of carbon nuclei in larval cuticles compared to adult cuticles implies slower motional dynamics with enhanced degree of sclerotization in adults. By investigating the internal structure and dynamics of cuticles, this research not only contributes to biomimetic material development but also enhances our understanding of structural changes across different developmental stages of B. mori.
