What seems to be clear to me is that after the primary infection most of the cells die indirectly, but at the later stage, when the viral load is very high, the virus kills a lot of cells directly.
Although each egg cell produced by a woman carries a single X chromosome, the sperm cells produced by a man carry either an X or a Y. This means, in very simple terms, that the sperm cell determines a baby's sex.

I was working with stem cells as part of a NASA programme. We realised that the science of stem-cell proliferation was also fundamental to cancer cells when cancer enters the phase of metastasis.
We keep thinking that the human is evolving. No, the human has evolved to its extent. What's happening now is the organization of humans: just like cells organize to form people, people are organizing to form humanity.
There are no bona fide treatments available for embryonic stem cells. There is nothing in the laboratory, and there is certainly nothing in the clinics available to patients.
Your cells are not working as hard as your dog's but harder than your horse's. The bigger the animal, the less energy needed to sustain a gram of tissue.
In my lab, we are always thinking about how cells, bacterial cells, can talk to each other and then organize themselves into enormous groups that function in unison.
A meticulous virtual copy of the human brain would enable basic research on brain cells and circuits or computer-based drug trials.
Battering down solar cells on the roofs of Wal-Marts in California. I think that will be some of the highest-return investments that anyone ever makes.
Babies have millions of brain cells. They are like light bulbs waiting to be turned on. Don't wait for them to go to school and hope for the best.
I've been thinking about the record since I reached the fifty plateau. But you think about it and then you let it go because you can't waste many brain cells on hours thinking about it.
So why in the world would anyone support the unethical, failed use of embryonic stem cells instead of the ethical, successful use of adult stem cells? Because they do not know the difference.
The cell is a city of production centres, each part working away like mad, and it's co-ordinated. Six trillion cells in a body - you can't help but be moved.
Water is commonly regarded as the 'solvent of life,' since our bodies are 70% water. All other vertebrates, invertebrates, microbes, and plants are also primarily water. The organization of water within biological compartments is fundamental to life, and the aquaporins serve as the plumbing systems for cells.
The Stem Cell Research Enhancement Act would expand research on embryonic stem cells by increasing the number of lines stem cells that would be eligible for federally funded research.
Al-Qaeda has a kind of loose, almost entrepreneurial structure with lots of cells in various countries that are semi-independent.
Where he was, where his cells were, where his logistical channels were, how he communicated. Who his allies were. Who donated to them. I think it's fair to say the entire range of sources were brought to bear.
Adult stem cells are also problematic, as they are difficult to identify, purify and grow, and simply may not exist for certain diseased tissues that need to be replaced.
Stem cells are probably going to be extremely useful.
I learned about HeLa cells in my first basic biology class, and I just became completely obsessed with them from that point on.
The laws are still very unclear. Cells are still taken from people without consent - a lot of people don't realize it.
I was what? - twelve years old - and I was thrown in the cells with these people, so I learned fast.
One day between takes on the 'Oz' set, I went into one of the cells and laid down and dozed off. When I woke up, I thought I was back in a federal pen. But I did my time, and today no one is more of a free man than Chuck Zito.
Able Danger was a top-secret military planning operation, established in '99 by the Chairman of the Joint Chiefs of Staff to identify cells of al-Qaida worldwide and to take out al Qaida terrorists. They identified five cells worldwide, one of them in Brooklyn.
Unlike the heart or kidney, which have a small, defined set of cell types, we still do not have a taxonomy of neurons, and neuroscientists still argue whether specific types of neurons are unique to humans. But there is no disputing that neurons are only about 10 percent of the cells in the human brain.
