The oldest inclusions found in meteorites, thought to trace the first solid material to form in the presolar nebula, are 4,568.2 million years old, which is one definition of the age of the Solar System. Studies of ancient meteorites reveal traces of stable daughter nuclei of short-lived isotopes, such as iron-60, that...

The single greatest advance in moving BNCT forward clinically has been the introduction of cyclotron-based neutron sources (c-BNS) in Japan. Shin-ichi Miyatake and Shinji Kawabata have led the way with the treatment of patients with recurrent glioblastomas (GBMs). In their Phase II clinical trial, they used the Sumitom...

In most, if not all proteinopathies, a change in the 3-dimensional folding conformation increases the tendency of a specific protein to bind to itself. In this aggregated form, the protein is resistant to clearance and can interfere with the normal capacity of the affected organs. In some cases, misfolding of the prote...

Upon heating, Δ9-tetrahydrocannabinolic acid decarboxylates to give the psychoactive compound Δ9-Tetrahydrocannabinol. When cannabis is heated in vacuum, the decarboxylation of tetrahydrocannabinolic acid (THCA) appears to follow first order kinetics. The log fraction of THCA present decreases steadily over time, and t...
