Developing low cost and stable metal electrode is crucial for mass production of perovskite solar cells (PSCs). As an earth-abundant element, Cu becomes an alternative candidate to replace noble metal electrodes such as Au and Ag, due to its comparable physiochemical properties with simultaneously good stability and low cost. However, the undesirable band alignment associated with the device architecture impedes the exploration of efficient Cu-based n-i-p PSCs. To solve this problem, researchers in China investigated the energy-level difference at different interface and offered potential path forward to achieve more efficient n-i-p PSCs with Cu electrode.

Higher levels of a key inflammatory marker were related to older breast cancer survivors reporting cognitive problems, researchers found in one of the first long-term efforts to examine the potential link between chronic inflammation and cognition in older breast cancer survivors.

Cleveland Clinic has been selected as a founding partner and the leading healthcare system in a new initiative meant to spur collaboration and innovation in the quantum computing industry. Based in Greater Washington, D.C., Connected DMV and a cross-sector coalition of partners are developing the new Life Sciences and Healthcare Quantum Innovation Hub to prepare the industry for the burgeoning quantum era and align with key national and global efforts in life sciences and quantum technologies.

Neurons in an area of the brain responsible for memory were significantly larger in SuperAgers compared to cognitively average peers, individuals with early-stage Alzheimer’s disease and even individuals 20 to 30 years younger than SuperAgers — who are aged 80 years and older, reports a new study. The study of was the first to show that these individuals carry a unique biological signature that comprises larger and healthier neurons in the entorhinal cortex that are relatively void of tau tangles.

Health, care and social services should be designed to be more sensitive to the shame felt by their clients, patients and service users, experts have said. Using a ‘shame lens’ can transform interactions between professionals and those they work with, according to a new study.
