NASA Scraps All-women Space Walk

The US space agency NASA scrapped a planned historic spacewalk by two women astronauts, citing a lack of available spacesuits that would fit them at the International Space Station.
Christina Koch will now perform tasks in space with fellow American Nick Hague, instead of Anne McClain as originally planned.
Had Koch and McClain done their spacewalk together, it would have been the first ever by two women astronauts.
Until now, male-only or mixed male-female teams had conducted spacewalk since the space station was assembled in 1998, 214 spacewalks until now.

Kit to Identify Genetically Fit Sperms for IVF

In what could prove to be a significant breakthrough in In-Vitro Fertilisation (IVF) technique, a scientist associated with Lucknow-based Central Drug Research Institute (CDRI) has come up with a kit capable of identifying genetically fit sperms.
The single-use kit, which will hit the market by mid-2020, can help in identification of epigenetic markers on the DNA of the sperm.
Through these markers, we can establish whether the DNA is genetically fit or not.
