Twitter Announces First Profits

The social media site Twitter has announced its first profit since the founding of the company in 2005. The last quarter of 2017 saw the company making $ 91 million in profits. After the announcement, Twitter shares rose more than 20%.

Twitter made the profits from an increase in ad sales and from expansion outside the US.  Overall revenue has been increasing constantly and is now at $ 731 million, due to a better targetting of ads. While revenue in the US fell, it increased strongly in Japan and other countries.

Currently, Twitter is reported to have over 330 million active users. It has been an important media outlet for celebrities and politicians, especially in the United States, for a long time. However, surprisingly, up to now, the company has failed to make any profits. Business experts have criticized Twitter for failing to grow over the longer term and step out of the shadows of its bigger brother, Facebook.


The company has announced its plans for 2018.  It wants to improve the quality of information and tackle security issues, for example, fake accounts and spam. As many as 15% of all accounts on Twitter are said to be controlled by bots.

Amazon Go – The First Automated Store

Amazon has opened its first automated store to the public. Amazon Go is a grocery store located on the ground level of the corporation’s Seattle headquarters.

The store, which offers food, salads and boxed meals could revolutionize our shopping experience in the future.

As soon as you arrive at the store, a cell phone app connected to an Amazon account registers your presenceEverything that happens in the store is tracked by hundreds of infrared cameras. When you pick up items from the shelves they are automatically put into your virtual shopping cart. The cameras also detect when you put an item back on the shelves and remove it from your cart. The moment you walk out your account is charged without making any physical payment.

The technologies used at Amazon Go are the same as with driverless cars –  computer tracking, weight sensors on shelves and complicated algorithms.

The 1,800 square foot store has been open to Amazon employees for a year. Now the public can also shop there.

However, not everything has been running smoothly in the store’s opening year.There were hardships to overcomeFor example, it’s hard for cameras to distinguish between different flavours or products that look the same. They also have problems handling people who move around or identifying shoppers with similar body sizes and clothes.

Even though there are no checkout counters and cashiers who make you wait in line, there are shop assistants who restock goods and help customers find their way around.

World Health Organisation Introduces Gaming Disorder

The World Health Organisation has added the term “gaming disorder” to its International Classification of Diseases. It refers to people who are addicted to video and other games and cannot stop. It is the first update in the WHO’s catalogue in almost three decades.

According to the WHO, gaming becomes a disorder if you are unable to control how long you play and when to stop. When that happens, it gets control of your life, influences everyday situations and affects your daily routine. WHO officials say that excessive gaming is  a serious disorder that must be closely watched

In order for a person to be regarded as having a gaming disorder, the behaviour must be going on for at least one year, either constantly or in phases. Gamers put their addiction above their family life, meeting with friends and going to school.

On one side studies have shown that playing video games may help with problems like depression and dementia.However, gaming is highly addictive and many people play for a longer time than is healthy. As a result, people get fired for not going to work or miss school classes for a longer period of time.

Many continue with their addiction, even if they see and realize the negative consequences it leads to.

NASA Discovers Star System With 8 Planets

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 average surface temperature of about 400° C. It moves around the star once every 14.4 days.

The discovery was made based on data provided 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.

Automation Could Cost Up To 800 Million Jobs

Up to 800 million people worldwide could lose their jobs because of automation. About half of them will have to learn new skills to get another job. In the United States alone, up to a third of the workforce could become unemployed within the next few decades. These are the results of a recent publication by McKinsey Global Institute.

Jobs that involve manual or factory work are the ones that are most at risk. People who work in social fields, the environment or management are less likely to lose their jobs. In countries with ageing populations, more jobs will be needed in health care.

The report says that there is no reason to panic because new job fields will emerge which will more than compensate the loss of traditional jobs. In addition, economic activity and rising productivity will also provide for more jobs.  However, workers will need to adapt to jobs more quickly than before and lifelong learning will be essential.

Artifical intelligence is already spreading quickly in some areas. Technological inventions, like self-driving cars, will become hugely popular within a decade. More jobs will be needed in the energy sector and people will find more work building modern infrastructure in cities.

However, governments around the globe will have to give support and spend money on programs to train workers for new tasks.

The report states that the situation today is similar to the beginning of the 20th century when agricultural societies became more and more industrialised.  The invention of the automobile contributed to this change. In the 1980s the computer revolution eliminated some jobs but created many others.

China Overtakes US in Number of Supercomputers

For the first time in history, China has overtaken the United States in the number of supercomputers.  Currently, China has a total of 202 of the world’s 500 fastest computers, up from 159 half a year ago. The number of US supercomputers has dropped to 144.

The world’s most powerful computer is located in China. The Sunway  TaihuLight ,  at Wuxi can do 93 quadrillion calculations per second. The fastest US computer, the Titan, is ranked fifth while Europe’s speediest computer is Switzerland’s Piz Daint, ranked third.

Supercomputers are machines that occupy entire buildings and use the combined power of thousands of processors. They are used to carry out special tasks that involve a huge number of calculations.  Among them are weather forecasts and climate studies, as well as strategic tasks like nuclear weapons simulations.

Chinese supremacy in the world of supercomputing reflects the country’s  investment in research and development. One-fifth of the money used on research and development around the world is spent in China.

On the other side, many Chinese systems have been created to earn money. Processing power is rented to other national and international companies.

For years the speed of supercomputers has steadily increased although since 2012 this increase has slowed down.
