Scientists have developed a wireless 'in-body GPS' system named "ReMix" that can accurately locate ingestible implants and track tumours inside the body. ReMix was able to track implants with centimetre-level accuracy in animal tests. Similar implants can be used to deliver drugs to specific regions of the body. The test was conducted by scientists from Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital (MGH) in the US. ReMix is not accurate enough to be implemented in clinical settings as of now. For actual implementation, the margin of error should be closer to nearly two millimetres.

On World Earth Day- April 22, 2019 the State Bank of India (SBI) has launched India's first 'Green Car Loan' (Electric Vehicle) to encourage customers to buy electric vehicles. The new scheme 'Green Car Loan' will offer loan at 20 basis points lower than the interest rate on the existing car loan schemes. The scheme comes with the longest repayment period of up to 8 years. It is thus a strategic inclusion to SBI's auto loan segment that is offered with zero processing fee for the first 6 months of the launch. SBI has already notified 100% migration to EVs (Electric Vehicles) by 2030 in order to decrease carbon footprints, thus being in line with the government's pledge of ensuring 30% EVs on road by 2030.

Iran announced it will pull out of some commitments under 2015 international nuclear agreement signed with world powers, called Joint Comprehensive Plan Of Action (JCPOA). Iran said it will stop suppressing its stocks of enriched uranium and heavy water, as these are needed by certain types of the reactor for nuclear fission to take place. It mentioned that such actions are required from Iran as the European Union (EU) and other countries did not have the power to resist US pressure. The move is to secure Iran's rights and bring back the balance after the United States exited from an agreement in 2018.

NASA's the Transiting Exoplanet Survey Satellite (TESS) has discovered an Earth-sized planet, HD 21749b and a "sub-Neptune" world, revolving around the star, HD 21749. The star lies 53 light-years from Earth. The research study has been published on 15th April, 2019 in 'The Astrophysical Journal Letters'. TESS was launched to Earth orbit in April 2018 on a SpaceX Falcon 9 rocket. One tool termed as 'Planet Finder Spectrograph' (PFS) on the 'Magellan II telescope' in Chile helped to confirm the planetary nature of the TESS signal and measure the mass of HD 21749b. HD 21749b is about 23 times heavier and 2.7 times wider than Earth. It is gaseous, has a substantial atmosphere but not as puffy as Uranus and Neptune. HD 21749b has an orbital period of 36 Earth days.

Japanese unmanned spacecraft, Hayabusa2 reached Asteriod Ryugu on June,2018. Since then, the spacecraft landed multiple robotic probes on its rocky terrain of the Asteroid Ryugu.The spacecraft had surveyed 69,000 locations covering almost 90 percent of Asteroid Ryugu by using a near-infrared spectrometer capable of detecting hydrated minerals.According to its study published in U.S. Journal Science,the spacecraft probed and found the small amounts of minerals containing water on the surface of the asteroid.A part of the water might be from asteroids and comets.
