COVID-19 warnings were on Twitter well before the outbreak of the pandemic
A new study of researchers at IMT School for Advanced Studies Lucca, published in Scientific Reports, has identified tracks of increasing concern about pneumonia cases on posts published on Twitter in seven countries, between the end of 2019 and the beginning of 2020. The analysis of the posts shows that the "whistleblowing" came precisely from the geographical regions where the primary outbreaks

How complex oscillations in a quantum system simplify with time
Quantum physics allows to make statements about the behavior of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars.

Platinum complex inhibits metastasis through conformational modulation of heparan sulfate
Cisplatin has been used to treat cancer since the 1970s. Since then, many other platinum-containing cytostatic drugs have been developed, such as triplatinNC, a highly charged complex that contains three ligand-bridged platinum atoms. Unlike cisplatin, this drug also directly inhibits metastasis. The reason for this seems to be modulation of the geometry of a sugar component of heparan sulfate, an
