Here is some news of the future.

March 20. 2035

There was a lot of news around the life extension drugs that hit the market a decade ago. They didn't promise that you would live forever. but they gave you a chance to extend your life an extra five to ten years. Even though the life expectancy rate at birth has increased greatly. the life expectancy for seniors hasn't improved that much. Basically. you have a greater chance to become a senior, but you will not have a much longer lifespan, and this is where the anti-aging drugs intend to kick in. So ,do the anti-aging drugs work? Well. it is too early to tell. But the sales so far are very good.

Of the total US population of 378 million, people over 65 years of age now make up 20% for the first time. The senior ratio was only 4.1% by year 1900. and l2.4% 30 years ago.

The number of people above 65 compared to those of what is considered working ages. between 15 and 64. is currently 33.7%. This is up from l85% since year 2005. which means that for every retired person there are now two workers. compared to four workers 30 years ago. The number of people above the age of 80 has grown t0 23.8 million; making them 6.3% of the total population compared t0 3.6% in 2005.

Although introduced in the market only five years ago, 10% of all hydrogen fuel now sold in the US is of the environmentally friendly Re-Hydro label, produced through. eletrolysis (电解) based on a source of 1OO% renewable energy. Several producers have turned to producing Re-Hydro. mainly because of lower tax. which also keeps the price of. Re-Hydro on the same level as regular hydrogen. Most analysts believe that Re-Hydro will be the .dominating fuel in the future

Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.

Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator(猎食动物)gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.

Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.

Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.

Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.

Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them, and they don't need to share their food.

As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.

How the Grand Canyon (大峡谷) was created remains one of the geology’s greatest mysteries. Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years. But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead.

Down-cutting is when a flood of water rushes over a landscape (地形) with enough force to cut deeply into the ground and leaves behind a canyon. Such a flood is usually released when a natural or man-made dam (堤坝) bursts.

Robert Webb, a research geologist, says natural dams seem to have formed and broken across the Colorado River several times during the last million years. The dams were built when lava(熔岩) from the eruptions of nearby volcanoes flowed into the river. The lava hardened into hard rocks and blocked the river, causing it to back up and form a lake. Each time the lake grew so huge that it broke the rock dam, releasing a flash flood that furthered the down-cutting process and deepened the canyon.

Down-cutting is not just an earthly event. Satellite photos sent back from Mars suggest that the process has happened there, too, say many other researchers.

The photos, taken by the Mars Global Surveyor, indicate that an enormous lake existed on Mars 3.5 billion years ago. The lake spilled into a large nearby hole. One edge of the hole broke, releasing a flash flood that quickly carved out a grand canyon.

The existence of down-cutting on Mars is just one more piece of evidence that the cold, dry planet was once warm and wet.
