AlphaFold – AI Tool

AlphaFold is an AI-based protein structure prediction tool. It is based on a computer system called deep neural network.
Inspired by the human brain, neural networks use a large amount of input data and provides the desired output exactly like how a human brain would. The real work is done by the black box between the input and the output layers, called the hidden networks.
AlphaFold is fed with protein sequences as input. When protein sequences enter through one end, the predicted three-dimensional structures come out through the other.
How does AlphaFold work?
It uses processes based on “training, learning, retraining and relearning.”
The first step uses the available structures of 1,70,000 proteins in the Protein Data Bank (PDB) to train the computer model. Then, it uses the results of that training to learn the structural predictions of proteins not in the PDB.
Once that is done, it uses the high-accuracy predictions from the first step to retrain and relearn to gain higher accuracy of the earlier predictions.
By using this method, AlphaFold has now predicted the structures of the entire 214 million unique protein sequences deposited in the Universal Protein Resource (UniProt) database.

UNEP – World Environment Situation Room

The World Environment Situation Room implements the Big Data Initiative. The project is global with overarching environmental policy relevance and impact.
It includes geo-referenced, remote-sensing and earth observation information integrated with statistics and data on the environmental dimension of sustainable development.
The themes of this Global platform cover complementary dimensions for Global Green Solutions for the Environmen
It targets country policy makers, top environmental policy makers, the environmental scientific community, business and interested citizens.
The platform is essential as a knowledge instrument to support progress on delivering the environmental dimension of Agenda 2030 for Sustainable Development.
The World Environmment Situation Room will be implemented in different cities, countries and regions.
This platform will facilitate in tranforming data into information products and services which can be used by non-data experts.
