On Thursday, Delta Airlines became the first major carrier, which will cover the extra income taxes its employees in same-sex relationships pay for healthcare plans. These employees pay extra taxes in states, which don't recognize gay marriages.

This practice, introduced by Delta Airlines, is called ‘grossing up’, in which same-sex couples pay the same tax amount of healthcare as paid by legally married employees. According to the airline, this decision made by the airline will take effect without any delay and taxes will be covered retroactive to January 1. At present, gay marriage is legal in 37 states. But it is not legal in Georgia, where Delta is based.

March witnessed a consistent growth in US jobs giving hopes that interest rate will be increased this year in the Federal Reserve.

On Thursday, health officials said that the Shigella sonnei bacteria are causing more than 200 illnesses since last May, with large recent 45 cases in Massachusetts, 25 cases in California and 18 cases in Pennsylvania.

Many cases were traced to people who had recently traveled to the Dominican Republic, India or other countries.

The Hubble Space Telescope of NASA has captured images of goblin-green objects known as ephemeral quasar ghosts.

Quasar is a very luminous and compact region that surrounds a supermassive black hole at the centre of a galaxy. The Hubble observed them within eight different, distant galaxies. These unusual looped structures orbit their host galaxies and glow in a bright and eerie goblin-green hue.

According to scientists, these glowing structures have looping, helical and braided shapes and they don't fit a single pattern.

Quasars are the most active of these galaxy cores, where infalling material is heated to a point where a brilliant searchlight shines into deep space. The beam is produced by a disk of glowing, superheated gas encircling the black hole.
