UNICEF: First UN organisation to accept donation through Cryptocurrencies

United Nations Children’s Fund (UNICEF), the Children’s agency of the United Nations has now become the first UN organization to hold and make transactions in cryptocurrency. UNICEF now joins a number of other aid agencies that accept donations in cryptocurrencies, such as American Red Cross.

Key Highlights

The UNICEF has established UNICEF Cryptocurrency Fund, making UNICEF able to receive, hold as well as disburse donations via cryptocurrencies such as bitcoin and ether. Through the received donations, UNICEF will be funding open source technology that aims to benefit children and young people globally.

The Ethereum Foundation will be first one to be contributing to UNICEF through Cryptocurrency Fund, in form of donations to three grantees of UNICEF Innovation Fund. UNICEF is one of the co-leaders of UN Innovation Network and thus it already helps in researching the potential of blockchain (also other emerging technologies) and problems associated with them.

The organization’s latest move is another major step in its ongoing work related to blockchain and this move would help showcase Etherium and blockchain technology’s power to benefit communities all over the world.

New Antibiotic discovered in Mexican forests

The properties of newly discovered antibiotic have specific application in agriculture greatly. It is a soil bacterium and is known as “phazolicin”. This compound was unknown previously and was recently isolated in the tropical rain forests of Mexico.

The antibiotic is found in the root nodules of wild beans. They have their application both in medicine and agriculture. This antibiotic is fixed in the nodules by the symbiotic soil bacterium.

The antibiotic is a peptide. These peptides can bind to the ribosomes of the bacteria and are capable of messing with the protein synthesis.

Symbiotic Soil Bacterium

Nitrogen is the most commonly deficient nutrient in the soil. The plants cannot consume nitrogen directly from the atmosphere. However, it is highly essential nutrient for their growth. Plants absorb nitrates from the soil.

The Symbiotic Soil Bacterium infects the roots of leguminous plants and produce nodules. At these nodules, they fix nitrogen from the atmosphere in the form of nitrates and nitrites. Nitrates and nitrites are the absorb-able form of nitrogen for plants. The bacteria in turn receives food and shelter from the plant.
