When looking at cells with a microscope, the length of different stages of the cell cycle can be estimated using the formula: \(\text{Length of time in phase}=\) \(\frac{\text{observed number of ...

“And whenever an individual cell type does something cool or unexpected, it’s an interesting subject for figuring out how that happens.” To better understand how the multiciliation cycle worked, the ...

Here we show that the cell-cycle regulator p21 is involved in immune system function. T lymphocytes from p21 −/− mice exhibit significant proliferative advantage over wild-type cells following ...

The study addresses the complex regulation of HSCs, highlighting p21's multifunctional nature beyond cell cycle control. Through the use of p21-tdTomato mice, researchers differentiate between p21 ...

Sep. 19, 2024 — Can an immunoassay be created and selectively detect a virus in under 5 minutes? In a new study, researchers report that it can be done using a low-power laser like a laser ...

A life cycle is the series of stages something passes through during its lifetime. We also use the term for things that are not living, like cell phones. The life cycle for anything you buy includes ...

I've "taken" a variety of courses through Khan Academy, ranging from the hard sciences to business development. And when I was in college, I used the site to help re-explain some math concepts.

“Khan is now being kept in this tiny jail room, with no facilities, just for getting married,” Mr Khan’s Pakistan ...

Authorities have denied such claims. Mr Bukhari said Khan is not allowed to leave his two-and-a-half by three metre prison cell at all, other than for lawyer’s visits. Despite this, he says Khan ...
