What is a unit of nature? New framework highlights challenges for biodiversity credit market
Credit: Unsplash/CC0 Public Domain Ecologists have devised a new framework for classifying how biodiversity credit operators define units of nature. New analysis shows the challenges involved in devising a biodiversity credit market to finance nature restoration, and the risks of over-reliance on ‘offsets’. Nature conservation faces an estimated $700 billion annual funding gap to halt and begin reversing global biodiversity…

Researchers develop new covalent organic framework for precise targeting of cancer treatment
Credit: ACS Applied Materials & Interfaces (2024). DOI: 10.1021/acsami.4c10812 A team of researchers at New York University Abu Dhabi (NYUAD), led by Chemistry Program Director Ali Trabolsi, has developed nanoscale covalent organic frameworks (nCOFs), crystalline organic polymers modified with peptides, to treat the most aggressive form of breast cancer called triple-negative breast cancer (TNBC). The peptides enable the COF to…
