I'm extracting DNA from the legs of spiders which were euthanized by freezing in a household freezer. In almost every spider, the DNA shows a banding pattern associated with apoptosis. Why would there be so much programed cell death in the legs of spiders? Had it already happened naturally? Was it induced during the freezing process? I do not see this happening in other organisms using the same extraction procedure.
Each lane is DNA extracted from a different spider.

What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.Comfort, Nathaniel
How do scientists do disease surveillance and study biodiversity through the lens of genomics? Citizen scientist Blacki Migliozzi joined a group of jungle field researchers to find out.
Through anecdotes and stunning photography he will walk us through what it's like to work with big cats, primates, birds, bats, frogs, snakes and many other kinds of organisms. He'll also provide first-hand observations of the habitat loss endangering these ecosystems as well as the dangers scientists put themselves in when doing this important work.

Regulatory dissection of the severe COVID-19 risk locus introgressed by Neanderthals
Key functional variants, discovered using Massively Parallel Reporter Assay (MPRA) and reporter assays in the context of SARS-CoV-2 infection, support the importance of two critical chemokine receptor genes CCR1 and CCR5 in severe Covid-19 illness.Evelyn Jagoda (eLife Sciences Publications, Ltd)
