@la_roche1 Now I’m a researcher with many years of experience. This picture looks like a blood tube that has had the majority of the blood removed, and was not adequately washed with media. You could only prove this wasn’t the case if you removed the clot out of the tube.
@la_roche1 The red top tube is used specifically for the collection of blood samples that require serum, which is the liquid portion of blood obtained after the blood has been allowed to clot. When a blood sample is collected in a red top tube, it is left undisturbed for some time.

As stunning an image of our nearby universe as I have seen. Deep within the Eagle Nebula, find the “Pillars of Creation,” a stellar nursery made famous by the Hubble Telescope. Now laid bare by the infrared cameras of the @NASAWebb telescope.
