The covert nature of Brahe’s work was common among alchemists of the Renaissance, who kept their knowledge close to the vest. “Tungsten had not even been described at that time, so what should we infer from its presence on a shard from Tycho Brahe’s alchemy workshop?” Rasmussen said. In addition to serving as Brahe's home, Uraniborg functioned as a scientific center where students across Europe came to live and work. And Brahe himself wrote that the king was eager to support the scientist’s work in both astronomy and alchemy. Given the amount of gold found in Brahe’s remains, he may have also taken medicine containing potable, or drinkable, gold.

Multiple experts identified the presence of malware on the Pinduoduo app that exploited vulnerabilities in Android operating systems. Evidence of sophisticated malware in the Pinduoduo app comes amid intense scrutiny of Chinese-developed apps like TikTok over concerns about data security. Pinduoduo has previously rejected “the speculation and accusation that Pinduoduo app is malicious.”CNN has contacted PDD multiple times over email and phone for comment, but has not received a response. Google Play is not available in China, and Android users in the country download their apps from local stores. Engineers also found their access to big data, data sheets and the log system revoked, the source said.

Faptul că solstițiul de iarnă și apropierea celor două planete au loc în aceeași noapte este o coincidență, precizează NASA. Vom putea să-l vedem pe Jupiter cum se apropie și îl depășește pe Saturn, chiar în noaptea de 21 decembrie” spune Henry Throop, astronom NASA. Evenimentul astrologic este cunoscut sub numele de ”conjuncție” și are loc o dată la 20 de ani. Prima ”conjuncție” a fost observată în 1623, la 13 ani după ce Galileo Galilei a descoperit mai multe luni ale lui Jupiter, dar și inelele lui Saturn. De aceeași părere este și Carolin Crawford, care argumentează că ”acum 2.000 de ani, oamenii erau mult mai atenți la ceea ce se întâmplă pe cer”.
