MoU signed for online application under Pradhan Mantri Awas Yojana
Memorandum of Understanding has been signed by the ministry of Housing and Urban Poverty Alleviation and common service center e- Governance Services India Limited of the Ministry of Electronics and Information Technology.
Through this MoU, the Ministry of Housing and Urban Poverty Alleviation has enabled online submission of application by urban poor for affordable houses under the scheme.

Gelator to take out marine oil spills
Researchers at Indian Institute of Science Education and research (IISER) Thiruvanandapuram, has developed a gelator to solve the problem of marine oil spills.
What is marine oil spills?
It is a form of pollution. It is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas due to human activity. The oil is released into the ocean and costal waters from large ships where heavier fuels are used. It may be due to the spill of any oil refuse or waste oil.
What are the effects of marine spills?
Spilled oil can harm living things because its chemical constituents are poisonous. This can affect organisms both from internal exposure to oil through ingestion or inhalation and from external exposure through skin and eye irritation. It affects the overall ecological communities.
What is Gelator?
Gelator were produced using glucose as a starting material and after several chemical reaction.
The gelator molecule is partly hydrophobic and partly hydrophilic. While the hydrophilic part helps in self-assembling to form gelator fibres, the hydrophobic part is responsible for its diffusion into the oil layer.
Benefits of new scoop out method:
This newly developed gelator can be reused several times except in the recover of crude oil. It doesn’t cause environmental damage.
The current methods used in this recovery of marine oil spills are using oil booms, sorbents, using dispensers, skimming etc.
