1 of 2: Free event for students and recent graduates considering data science careers linked with the life sciences, part of London Data Week #LDW26 Data careers in life sciences Tue 7 July 2-4.30pm, One Triton Square londondataweek.org/ldw26-events... cc @cs4fn.bsky.social
Data careers in life sciences. Tuesday 7 July from 2pm to 4.30pm, free, at One Triton Square in King's Cross Knowledge Quarter.What happens when biology meets data science? New medicines, faster diagnoses, and whole categories of jobs that didn’t exist five years ago. And right now, the UK is one of the most exciting places in the world to be part of it.

​Data Careers in Life Sciences is a careers event designed specifically for students and recent graduates curious about where data science can take them in one of the UK’s fastest-growing sectors.

This event is hosted in the Knowledge Quarter – the King’s Cross innovation district home to some of the world’s leading life sciences and AI organisations – the afternoon is built to demystify where biology and data are colliding, the careers being created at that intersection, and how to break in.

Dear Lord Vallance,

Cuts to funding for astronomy and space science

We are writing to you as physics teachers in secondary schools and sixth form colleges, to express our grave concern at the cuts to funding for astronomy and space science, and particle and nuclear physics, proposed by the Science and Technology Facilities Council (STFC).

As you know, these amount to 30% overall, and project groups have been asked to plan for budget reductions of up to 60%. We urge you to take prompt action to reverse these cuts, the scale of which are without precedent in modern times.

Two hooded figures with lamps approach a moonlit, isolated cottage.
A woman answers the door.
We have come for the child, says the hooded figure
So soon? she asks
It is time, says the hooded figure.
The woman is distraught. We should never have got him a library card!
What is done cannot be undone, says the hooded figure
We couldn’t see the harm! We just wanted him to enjoy reading! 
For most, it ends there, says the hooded figure, turning away and walking into the wilderness
Oh lord, What have I done! says the woman,
the child walks past her and out into the darkness with them.
Do not cry mother.
