AI Thread Summary
Different types of lymphocytes, such as T cells and B cells, have a single dense nucleus without lobes, distinguishing them from granulocytes like neutrophils, which possess segmented nuclei. The lobes in neutrophils indicate their maturity, with the number of lobes correlating to their age; typically, neutrophils have up to five lobes. Eosinophils are noted for having a bilobed nucleus. The process of nuclear lobing in neutrophils is associated with the aging of these cells, reflecting their development and functionality in the immune response.

Why do the different kinds of
lymphocytes have different numbers of nuclear lobes?
Why do nuclei have lobes in the first place?

Lymphocytes do not have nuclear lobes. They only have one dense nucleus.

I think you mean some granulocytes like neutrophils. They have segmented nucleus. The more lobes a neutrophil's nucleus contains, the "older" it is. In other words, age of neutrophils are related to segments of their nucleus. Usually they have no more than 5 lobes. Moreover, eosinophils have a bilobed nucleus.

Thread 'Body dysmorphic disorder (BDD)'

https://www.nhs.uk/mental-health/conditions/body-dysmorphia/ Most people have some mild apprehension about their body, such as one thinks their nose is too big, hair too straight or curvy.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...

Thread 'Warning of new opiod drug (nitazene) on the streets: Question re strength...'

Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
