Researchers at Columbia University find evidence that healthy older adults can generate as many new brain
cells as younger people.
«We found that older people have similar ability to make thousands of hippocampal new neurons from progenitor
cells as younger people do,» lead author Maura Boldrini and associate professor of neurobiology at Columbia Universtiy says.
Researchers show for the first time that healthy older men and women can generate just as many new brain
cells as younger people.
Overall, the study found, older and younger brains had similar numbers of «intermediate» progenitor cells and «immature» neurons — signaling that older people had a similar capacity for generating new
cells as young people.

Hobson was upset — she remembered her early experience
as being all about paying her dues — but she realized something: «It all goes back to the
cell phone,» she says, meaning that since
cell phones have been around,
young people had access to instant answers (be it from their mom or Google).
Campaign staff also relied on
cell phones to reach segments of the population less likely to be on a computer regularly, such
as young people, minorities and the poor.

Eye diseases — such
as age - related macular degeneration,
as well
as a genetic condition called Stargardt's macular dystrophy that afflicts
young people — are considered excellent candidates for stem

cells are not
as likely to be rejected
as foreign compared with transplants elsewhere.

Sure enough, when the researchers examined the brains of PD patients, they found more
cells exhibiting signs of senescence than in
people without the disease — and especially astrocytes,
as they had expected.7 This was true even after matching patients for age, meaning that PD subjects had even more senescent astrocytes in their SNcs than is typical for
people their age (ranging in this case from 50 — 92 years at autopsy)-- and remember, aging already drives an increase in the burden of these
cells as compared with
young people, even in those who have yet to develop Parkinson's disease.7
Cells with similar characteristics accumulate during normal aging
as well
as in
younger persons infected with human immunodeficiency virus, suggesting that the process of replicative senescence is not an artifact of
cell culture but is also occurring in vivo.
The researchers also detected surprising numbers of aged beta
cells in
people as young as 20.
New bone formation is a continual process, and when GH levels are low, the supply of new
cells will decrease, and a
person will no longer be
as tall
as they were at a
younger age.

«Many
people, including our research group at Harvard, feel that the new digital media may bring about huge changes, and that these will emerge first with
young persons who have grown up with computers,
cell phones, instant messaging, online social networks, multi user games, and the like
as part of their daily environment.»
Strassberg, McKinnon, et al. conclude: «These results argue for educational efforts such
as cell phone safety assemblies, awareness days, integration into class curriculum and teacher training, designed to raise awareness about the potential consequences of sexting among
young people.»
