Thanks to their small size, low toxicity, and good tumor accumulation and penetration, these complexes represent a leap forward in contrast agents for cancer diagnosis, as well as neutron capture radiotherapy.</p>

<p>Pentoses are essential carbohydrates in the metabolism of modern lifeforms, but their availability on early Earth is unclear since these molecules are unstable. Now, researchers from Japan, the United States and Australia reveal a chemical pathway compatible with early Earth conditions, by which C6 aldonates could have acted as a source of pentoses without the need for enzymes. Their findings provide clues about primitive biochemistry and bring us closer to understanding life&#39;s origin.</p>

Tokyo Tech scientists showcased that donor doping within a mother material containing disordered intrinsic oxygen vacancies, as opposed to the commonly employed acceptor doping in vacancy-free materials, significantly amplifies the conductivity and durability of perovskite-type proton conductors within the temperature range of 250–400 ?.
