Newsnight's science editor Susan Watts and foreign news reporter Tim Whewell will leave the current affairs programme after their roles were made redundant.
Watts has worked at Newsnight since 1995. She can be found tweeting @susanwatts01.
Whewell joined the BBC Two programme in 2001. He can be found tweeting @BBCTimWhewell.
Newsnight editor Ian Katz has stated on social media that the programme remains committed to covering science but wants "to do it in a different way."
It is expected that correspondents both outside and within the BBC's network will be utilised for science and foreign news coverage.
