More than a hundred years after it had disappeared, Australia’s first submarine was finally discovered. The submarine, called AE-1 , went missing on September 14, 1914, with a crew of 35 on board. It was the first Allied submarine loss of the war.
After decades of searching, the missing Australian sub was found about 300 metresunderwater, off the coast of Papua New Guinea. It appears to be well-preserved and in one piece. Experts are now trying to examine the wreck and find out why the sub sank. They think it was probably an accident and not because of enemy fire.
The sub was on a mission to occupy German New Guinea, one of the German colonies in the Pacific.
In the past, there were 13 government – funded searches for the sub but, until now, none of them proved successful. When thesubmarinewasfound navyofficials held a commemorative service for the crew that the Australian navy had lost. Families were contacted and told that the oldest naval mystery in Australian history had finally been solved.

A human embryo that was frozen 24 years ago has now become a baby girl. Emma Wren Gibson was born in Knoxville, Tennessee from an embryo frozen in 1992. The mother, Tina Gibson, at 25, is only a year older than the embryo. It is the longest known frozen embryo that has successfully become a baby.
The Gibsons are unable to have children of their own and, in the past, have taken care of several other children.
Couples who use IVF to have a baby usually end up with more embryos than they need. They can decide to store them for later use, dispose of them or donate them for scientific research. Many parents who have leftover embryos give them to special centres where they can be used for others.
Doctors claim them frozen embryos can develop just as well as fresh ones. The dangerous part, however, is the thawing process.Only about 75% of all frozen embryos survive it. Health experts think that there may be up to a million frozen embryos in the United States.
For those who can’t have babies, using a frozen embryo from a donation centre is similar to adoption, only that the baby grows inside the adoptive mother.

California’s Department of Health has published new guidelines on how to handle cell phones. It warns that radiationemitted from cell phones can be harmful but does not say that cell phones are dangerous.
.Health authorities in California suggest a few measures cell phone users should take. When sleeping, you should keep your phone at least an arm’s length away from your body. You should also avoid keeping your cell phone in your pocket. They also recommend only using cell phones when reception is strong.
Some doctors agree that carrying cell phones close to your body could increase the risk of getting brain tumours , cancer and becoming infertile. It may also lead to headaches, hearing problems and a lossof memory. On the other side, there are many health experts who say that the risks cell phone usage present are not proven
Cell phones emitradiation in the form of low-energy radio waves when they receive and send signals from cell towers. The frequencies that cell phones use could be linked to various illnesses.
The new cell phone guidelines have existed since 2009 but not been published. Recently, a Berkeley professor won a lawsuit against the Department of Health to release the guidelines to the public and push for more action.

NASA has discovered the eighth planet of a star system, similar to our solar system. The star, Kepler-90 is over 2,500 light years away and larger and hotter than our sun. It is the first star known to have as many planets as our solar system.
The Kepler-90 star system is much more compact than our solar system. The outermost planet orbits the star at about the same distance as the earth orbits the sun. its inner planets are small and rocky while the outer ones are larger and made up of gas
The newly discovered planet, Kepler -90i, is the third celestial object in the star system. It is probably rocky and similar to our earth, but because of its closeness to its home star has an averagesurface temperature of about 400° C. It moves around the star once every 14.4 days.
The discovery was made based ondataprovided by the Kepler space telescope. Launched in March 2009, the telescope has constantly been scanning certain sections of the universe in search of new stars and planetary systems. Up to now, over 2,000 new worlds have been discovered.
To help analyse the data NASA has been relying on artificial intelligence software supplied by Google. This software examines weak signals of light when objects pass in front of a star. The new way of examining data is expected to reveal even more new planets in the future.

For the first time, scientists have recorded a humming sound that the earth has probably been producing for a long time. Scientists have been aware of the hum for decades, but for the first time, a team of experts have actually been able to record it
57 seismometers were placed over millions of square kilometres of the Indian Ocean. Ultralow radio frequencies were recorded on the ocean’s floor
For some time, geologists have pointed out that the earth is not silent but vibrates almost everywhere. However, it is a sound with a frequency thousands of times lower than what the human ear can hear.
Scientists don’t know what causes the earth’s hum but could learn more by getting a clearer audio signal. There are a few theories about where the sound may come from. Some say that it’s the echo of waves crashing onto the coast, while others think that it may be the atmospherein motion. Geologists, however, agree that the sound does not come from earthquakes because it is continuous.
In 1998 Japanese scientists proved that the earth’s hum was real, but nobody has been able to record it until now. Geologists hope that by analysing the recording they can get more information on the interior structure of the earth.

Boxing Day, the 26th of December, has become a traditional day of sports in the UK, with many events taking place all across the country.
The day got its name from a time when many upper-class families gave boxes of gifts to poor people who had to work at Christmas while everybody else was celebrating. Boxing Day is celebrated in many Commonwealth countries.
The first important sports event on Boxing Day took place back in 1860 when two of the oldest football clubs in England played against each other. Today the Englisch Premier Leagueschedules a full round of matches on this Christmas holiday. In many cases, teams that are geographically close to each other play on Boxing Day so that fans do not have that far to travel.
While most European football leagues take a winter break, sometimes for several weeks, English football continues between Christmas and New Year.
The holiday schedule is welcomed by many football fans, but there are criticshowever who say that the Christmas season is a time when everybody should be at home with their families. Some managerspoint out that the season is very long and major teams need a break for players to recover from injuries.
Football is not the only popular sport that is played on Boxing Day. Horse racing and rugby have also seen regular sports events on the second day of Christmas. Traditional fox hunting is opposed by more and more Britons. In addition, Boxing Day has become one of the strongest betting days of the year.

The International Olympic Committee has banned Russia from taking part in the 2018 Winter Olympic Games in Pyeongchang, South Korea. Russian officials are not allowed to take part in the opening ceremony and the Russian flag will not be raised.
Russian athletes, however, will be able to take part as individuals under a neutral flag if the IOC has determined that they have been clean athletes in the past.
The decision comes after the International Olympic Committee (IOC) confirmed that Russia was guilty of systematic doping during the 2014 Winter Olympics in Sochi. In a case of state-sponsored doping, officials tampered with urine samples to hide athletes’ drug abuse. More than 20 Russian athletes, among them some medal winners, have been disqualified from the final Sochi results.
The whole investigation into the doping claim started when Grigory Rodchenko, director of Russia’s anti-doping lab in Sochi 2014, defected to the United States. He stated that the country ran an official doping programme and switched samples during the Games. Doping was especiallywidespread in sports like biathlon and cross-country skiing. A report by the World’s anti-doping organization (WADA) stated that between 2012 and 2015 a thousand Russian athletes in 30 sports benefited from the programme.
Although many countries welcomed the IOC’s decision, it was sharply criticized in Russia. Some officials urged the country not to allow any of its athletes to take part in Pyeongchang Olympics. Russia would have ranked first in the Sochi medal table, but lost 13 medals because of the scandal, 4 of them in gold.

Facebook has announced that it will release a new version of its popular app Messenger for children aged between 6 and 12. They do not need their own Facebook account to access the app, called Messenger Kids.
With Messenger Kids, parents will be able to control what their children see and who they are allowed to communicate with. There are no ads in the children’s version and Facebook has promised not to use a child’s information for other purposes. In addition, children’s names will not be integrated into Facebook’s search tool. At the moment, the app will only be available in the United States.
Facebook aims at getting children to become used to its product even if they are under the age required to get a normal account. As the company is losing younger customers to rivals Instagram and Snapchat, the company is trying to get young users to connect to their product before competitors do.
Messenger Kids will offer text and video chat as well as stickers and drawing tools. Special detection filtersprevent children from sharing sexual content or violence online.
According to Facebook, over 90% of all 8 to 12-year-olds have smartphones or tablets. Many use their parents’ Facebook account.The new app is intended to give children a feeling of having their own account, while parents are still incontrol.Messenger Kids will not automatically be converted into a normal Facebook account when children reach 13.

Short Message Service (SMS), also called texting, is celebrating its 25th birthday. The first text message was sent in Great Britain shortly before Christmas in 1992 in Great Britain. It was British engineer Neil Papworth who sent the first message from a computer to a mobile phone on the Vodaphone network. At that time mobile phones could only receive messages, not send them.
In 1994, Nokia presented its first mobile phone that could actually send and receive messages. It was the first phone that could produce more than an audio signal. Shortly afterwards the first commercial SMS service started in Finland. Text messages were limited to 160 characters.
25 years later text messaging is widelypopular. 97% of all smartphone users send some type of text message regularly. About 25 billion are sent every day. Today there are more complex messaging services like WhatsApp, Facebook Messanger and iMessage.
Media experts regard texting as the first step towards today’s smartphones, which are basically pocket computers with countless apps.
Texting has changed the way we communicate. For the first time, you could send the same text to different contacts at the same time andit didn’tmatter if the recipient was reachable or not. A new language has also emerged with abbreviations and short sentences.

Voyager 1 is the first man-made object to leave the solar system. 37 years after it was launched, NASA’s engineers fired the spacecraft’s backupthrusters. The primary thrusters have been getting weaker over the last few years.
Voyager’s thrusters were fired for a few milliseconds from a distance of 13 billion miles in order to reposition the spacecraft so that the antennae would point towards earth.
Nobody at NASA knew if firing the thrusters would work after decades of inactivity. After 19 hours, the time which it took for the signal to get back to earth, it was confirmed that the thrusters had actually been fired. Voyager 1 will now be able to operate and send data back to earth for another 2 to 3 years.
As Voyager 1 software dates back to the 1970s, scientists had to examine the software code to make sure the engines worked correctly.
Voyager 1 and its twin Voyager 2 were launched in 1977 to carry out a grand tour of the solar system. They passed Jupiter, Saturn, Uranus and Neptune. After that, the spacecraft kept on flying and passed the boundaries of the solar system. In the past decades, the two spacecraft made great discoveries, including active volcanoes on Jupiter’s moon Io and a methane atmosphere on Saturn’s moon Titan.
Although Voyager 2’s thrusters are in a better condition than it’s sister craft NASA also plans to fire them in the near future.
