Survival realizable complex team. And flying Robots In Disguise sent out to scare unsuspecting. First before we even see the light of day our biological clock has already started ticking. We grow older and birthdays pass by year after year but how and why do we age scientists are trying to understand more about the process so they can slow it down or even make it stop. Us michelle might want drives me the most use finding out why we age the item. On and. On desperate to find out how it works. And how we can intervene. Through treatments and medications to slow the aging process. Biostatistician steve harvey of the University Of California In Los Angeles for years hes been researching a method to test the biological age of humans. One of the biggest hurdles weve had in Aids Research is that we had no way to measure aging. People used to say there were pills that kept you young but we couldnt verify it because we couldnt measure the process. New testament. For time researches attempted t

Of what we want to do now is see if we can use these clocks to determine how molecules or genes are affecting the clock. Does that work its prime force the. The mystery of why we age is still unsolved but the first veil of that mystery has been lifted. Slowing down or even reversing the Aging Process Scientists might not be far from finding the answer but even without that our average Life Expectancy is increasing. Its estimated that in one hundred years time
through soil and over rocks it picks up sodium chloride a mineral formed when the metal sodium reacts with chlorine gas. you don t detect the sultan fresh water lakes and rivers because the concentration there is too low . but as the rivers transport the water into the oceans the salt accumulates over time along with more released from benson the ocean bottom. as a result one leader of sea water contains about three tablespoons of salt on average. that s one good reason why you really don t want to drink ocean water. but why doesn t the sea continue to get salty or. that s probably because some of the dissolved salt is constantly being removed from seawater to form new minerals deep down on the seabed. when sea water seeps into the shore along the coast it also leaves salt the posits there
together lots of species seem to demonstrate collective intelligence. one thing salt water fish don t need to learn is how to deal with all the salt in the water they live in whenever they drink lots of salt enters their blood luckily they have specialised cells in their gills that transport it back into the water. which brings us to an interesting question that our viewer francisco not for in mexico has posed. why is the ocean so salty is someone constantly pouring salt into it just the opposite so farmers harvest the minerals from the sea so we can later sprinkle it on our food. the ocean so begins its journey when it rains in the mountains for example. as the. water flows through soil and over rocks it picks up sodium chloride a mineral formed when the metal sodium reacts with chlorine gas. you don t detect
