The results of a recent experiment to slow the effects of

the aging process in mice amazed scientists in Boston, USA.

The scientists increased the amount of an enzyme called

telomerase in the cells of the mice. Telomerase is an

important enzyme because it repairs DNA. With increased

telomerase in their cells, the mice’s fertility improved, their

fur began to look healthier, even their brains worked better.

The scientists were hoping simply to slow the aging process

in mice but, much to their surprise, they actually reversed it!

Could we use the same process to stop humans from

aging? It’s possible, but it wouldn’t be without risks.

Scientists believe increasing the level of telomerase in human

cells would put people at greater risk of cancer. What’s more,

it’s unlikely that simply increasing telomerase would be

enough to keep us young because hundreds of enzymes are

involved in the aging process.

Although scientists don’t yet know exactly how and why

we age, they have several theories. One theory is that as time

passes, our bodies become less efficient at removing toxins

from our cells. One way to try to stop the aging process is to

keep cells as clean as possible. Scientists in New York

successfully used this technique to restore the livers of old

mice. The researchers bred special mice that did not lose their

ability to remove damaged proteins from their livers. When

these special mice were two years old, their livers were as

healthy as the livers of ordinary one-month old mice.

Although these special mice with youthful livers didn’t live

any longer than ordinary mice, scientists believe this study

could eventually lead to ways of protecting humans from the

diseases we get in old age.

Of course, if scientists ever do succeed in developing

drugs that combat the aging process we will need to ask

ourselves whether it is right to use them. For instance, should

we keep people young and healthy artificially when, already,

there are far too many people on the planet?

What if you can’t wait for these future developments

though? Well, scientists may not yet be able to stop you from

aging, but they do know a way you can keep yourself looking

younger – tomatoes! Tomatoes contain a substance called

lycopene which helps prevent one of the main causes of skin

aging: sun damage. Researchers in the UK asked a group of

people to eat a serving of cooked tomatoes every day for 12

weeks. They then compared their skin to the skin of people

who hadn’t eaten any tomatoes. The skin of the people who

ate the tomatoes was much less likely to burn in the sun.

Eating tomatoes also increases the levels of procollagen in

your skin. Procollagen helps keep skin firm, so the more you

have in your skin, the less likely you are to get wrinkles. So

while living forever is still just a fantasy, nature has at least

provided a way for us to keep looking as young as possible,

for as long as possible!
