Saura Jalnidhi scheme
Odisha Government has launched Saura Jalnidhi scheme to encourage use of solar energy in irrigation by farmers.
Key features of the scheme:
The beneficiary of this scheme will be farmers who have valid farmer identity cards and have minimum 0.5 acres of agricultural land.
Under this scheme, farmers will be given 90% subsidy and 5,000 solar pumps. This will provide irrigation benefits in 2,500 acres of the state.
In the first phase, this scheme will be available in those areas where electricity is not available for running the pump set.

After two years travelling through space, the NASA OSIRIS-REx spacecraft has started to obtain images of the mission target, primitive asteroid Bennu.
The launch of the NASA OSIRIS-REx mission took place on September 8, 2016. Since then, the spacecraft has been two years travelling through space to reach its target, primitive asteroid Bennu, in October, 2018.
Aim of this Mission:
The aim of the mission is to collect a sample of regolith- the loose, soil-like material which covers the surface of the asteroid.
In July 2020, the probe will move to within a few metres of Bennu, extending its robotic arm to touch the asteroid’s surface. The arm will make contact with the surface for just 5 seconds, during which a blast of nitrogen gas will be used to stir up the regolith, allowing it to be sucked into the sample collector.
OSIRIS-REx has enough nitrogen on board for 3 sample collection attempts, and NASA are hoping to collect between 60 and 2000g of regolith material to bring back to Earth.

Palau becomes first country to ban sunscreen to save coral reefs
The Western Pacific nation of Palau has become the first country to ban many kinds of sunscreen, in a move to protect its coral reefs from chemicals that scientists say cause significant damage.
Under the ban, which will take effect in 2020, “reef-toxic” sunscreen — defined as containing one of 10 prohibited chemicals, a list that could grow later — can be confiscated from tourists when they enter the country, and retailers who sell it can be fined up to $1,000.

IIT Roorkee team uses tamarind seed protein to treat chikungunya
Researchers have found that a protein found in tamarind seeds reduces the infectivity of chikungunya virus by 64% and the virus RNA levels inside infected cells by nearly 45%. Based on the promising results obtained through in vitro studies, the researchers are planning to test the protein on animals to prevent and/or treat chikungunya infection. Currently, there are no drugs to treat chikungunya or any vaccine to prevent it.
The tamarind protein (tamarind chitinase-like lectin or TCLL) binds to the sugar moiety (N-acetylglucosamine or NAG) present on the surface of chikungunya virus.
When TCLL protein binds to the NAG sugar moiety it nearly coats the virus particles thus preventing the virus from binding with the receptors on the host cells.
Since binding to the host cell receptors, which is the first step in the infection process, is nearly prevented, the ability of the virus to infect the host cells is compromised.
Who found that?
Pravindra Kumar’s team at IIT Roorkee research and clear that the TCLL protein specifically binds to NAG sugar molecules. They found one protein has both anticoagulant and blood thinning properties while TCLL, which is a lectin protein, binds specifically to NAG sugar molecules.
They found that chikungunya virus treated with the TCLL protein showed nearly 64% reduction in the ability to infect host cells. But in the case of NAG-treated TCLL, the reduction in chikungunya virus infectivity was just 14%.
