Mount Agung is a volcano on the popular tourist island of Bali in Indonesia. The volcano is expected to within hours. More than 134,000 people have been to safe areas. They are now far away from the volcano. However, some have to leave. These people do not want to leave their homes.They have to take care of their farms and animals.

On September 28th, steam appeared above Mount Agung. Scientists fear that an eruption could happen soon. The news has tourists from coming to the island. Tourists left on the island say that many shops are closed. They also say that it is not possible to buy fresh fruits or vegetables. Some scientists think that the volcano could erupt in five minutes or five months. They just don’t know.

Americans love chicken. In fact, it’s the most popular meat in the United States. Americans eat more than eight billion chickens per year. But bringing all of that chicken to the dinner table creates a lot of big problems. Meat production is bad for the environment and the welfare of the animals. Plus, it’s really quite inefficient and unsustainable.

Well, a high-tech food company in California may have the solution. In March of this year, Memphis Meats, a pioneer in the “,” announced the first chicken meat grown in a lab from chicken cells. They invited taste-testers to sample the chicken in front of the media. Those who tried it said that it tasted like real chicken, but a little spongier.

You may have to wait a while before you see the high-tech chicken in your local supermarket. It’s still extremely expensive to produce. They estimate that one kilogram costs almost 20,000 dollars. According to the company that price should come down, and they plan to release a reasonably priced product by 2021.

A lot of us would love to go to work by bicycle. There are lots of reasons to switch. It’s good for the planet. It’s certainly healthier. And who really enjoys sitting in traffic?

On the other hand, it’s no fun starting out your workday all sweaty and tired. An e-bike seems like a perfect solution, but up to now they have been too heavy and ugly.

Enter the Volta, one of the most innovative e-bikes on the market now. The Volta weighs only 15.8 kilograms. That’s light enough to easily carry upstairs. The Volta comes with lots of options and features. You can choose a low maintenance, mess-free belt drive or a traditional chain. The rear-mounted motor makes steering it very natural. And it looks great; the battery is hardly visible, but it is able to give you a 64-kilometer range. And the motor has the power to take you up the steepest hills in your route.

It has other great features like headlights and taillights which automatically activate in low-light and an automatic brake light. It comes with a built-in GPS tracker in case your bike is ever lost or stolen.

Mount Etna is a volcano located in southern Italy. It is on the island of Sicily. Now, Mount Etna is spewing out red hot rocks and ash. However, experts say that there is no danger for people.

Mount Etna has often erupted in the past. The last eruption was in 2014. Even now a stream of molten rock is flowing down the mountain. This is called a lava flow. The volcano is also spewing out clouds of dust. Scientists say that these clouds are not so bad this time.

Experts say, people do not need to be afraid. Even for those who live close by there is no immediate danger.

No one is sure how long the volcanic eruption will last. Sometimes it is over after a few days.

Mt. Etna is the second most active volcano on earth. Only Hawaii’s Kilauea is more active.

Bringing the Mammoth Back

Bringing the Mammoth Back

The woolly mammoth was a very large elephant-like mammal that lived on Earth several thousand years ago.  Some mammoths grew to be four meters high and the largest weighed almost nine tons.  Both male and female mammoths had very large tusks and walked on every continent except Australia and South America.  Sadly, these giant creatures became extinct.

The last mammoths lived as recently as 4,000 years ago and their well-preserved bodies can be found frozen in the tundra of Siberia.  Because their bodies were so well protected from decay in the permafrost, their genetic material remained intact.  

Scientists at Harvard University are researching ways to bring the mammoth back to life. According to these researchers, it is possible to program the Asian elephants’ genes with a mammoth’s genetic material. This is can be done because of a recent scientific developments in gene editing using a new tool called Crispr. Crispr allows scientists to cut out specific genes and replace them with different ones. They estimate that we will see a living mammoth in less than 10 years.

A Dramatic Increase in Garbage in the Arctic

Arctic Garbage slow Arctic Garbage fast

There are very few people living in . You would not expect to find much garbage there. Recently, however, some German researchers have discovered a lot of plastic, glass and other waste in the sea there. They say that there is twenty times more garbage than compared to ten years ago.

polar bear small

The researchers are not exactly sure what is causing the increase in the amount of garbage there. It could be coming from very far away. Ocean currents can spread things over many kilometers. Another factor may be climate change. Ice cover in the Arctic has been shrinking. This has lead to more fishing and tour boats coming into the region. Some of the litter could be coming from these sources.

Ocean garbage is dangerous. Fish and other animals can die. Animals often suffocate when they try to eat plastic bags. Also, it is not healthy for people who eat the fish.

Which do you believe? Please choose one.


The Arctic is the part of the earth above 66° 34′ N. Above this latitude the sun does not set on the day of the summer solstice (the longest day of the year in the northern hemisphere), and does not rise on the winter solstice (the shortest day of the year in the northern hemisphere.

Last year the world was hot like never before. That is according to international weather researchers. They say it was due to climate change.

Weather researchers from the United States and Switzerland measured the temperatures around the world. They compared the temperatures ​​with previous years. The conclusion: 2016 set a new heat record for the world. The scientists say that this climate change was caused by human activity.

In 2015, many countries gathered in Paris and adopted a treaty to protect the climate. The countries there agreed that we should not let the earth’s temperature go up more than 1.5 degrees Celsius. These new measurements show that this will be very difficult.
