Scientists have shown that human T cells “see” the same set of highly conserved protein regions in different betacoronaviruses, from SARS-CoV-2 to its “relatives.”

A team of chemists has shown that each tablet has its own “biometric” trace – not a fingerprint, but an isotopic signature. By measuring the proportions of stable isotopes of hydrogen, carbon and oxygen (δ²H, δ¹³C, δ¹⁸O) in finished ibuprofen preparations, the researchers were able to confidently distinguish between products from different manufacturers and even individual batches.

A team from China has come up with a simple but daring trick: take tumor cells, “kill” them with a solution of iron chloride (FeCl₃), which causes them to become rigid, non-dividing, and… magnetic in seconds.

Lilly is testing orforglyprone, an oral (tablet) GLP-1 drug. In a large study (3,127 adults), the highest dose resulted in an average loss of 27.3 pounds (≈12.4% of body weight) over 72 weeks.
