Scientists have found one answer to water shortages. It is a new material that collects water from the air. They got the idea from a beetle that lives in an African desert. The deserts in Namibia are very dry, but the Namib beetle is an expert at surviving in dry conditions. Its shell is covered in small bumps that collect drops of water from the air. It is enough to keep the beetle alive. Scientists studied the shape and material of the bumps. They now want to make their own materials that can collect water from the air. This will help people who live in very dry areas.

Scientists say it isn't just sad things that make us brokenhearted. Happy events can also be bad for our heart. A broken heart is a real illness. It's not just the sadness we feel when something bad happens. We get broken heart syndrome when we are stressed and during emotional times, such as a relationship breakup, the death of family and friends, or the loss of a job. The medical name for this is Takotsubo Syndrome (TTS). People can get it, and be at risk of death, when very happy things happen. The doctors who discovered this have called it "happy heart syndrome".

The number of young people without a job is very high in many countries. There are 73 million 15-24-year-olds around the world who want to work but cannot find a job. The International Labour Organization (ILO) said that although youth unemployment is coming down in rich countries, it is rising in Asia, the Middle East, North Africa and Brazil. The rate in China increased from 9.3 per cent in 2010 to 10.6 per cent last year. It could be 11.1 per cent in 2016. In Brazil, the figure was 14 per cent at the beginning of this year, but is now almost 16 per cent.

One in three British people born this year will suffer from dementia in their life. Dementia is when the brain no longer works properly due to illness, old age or injury. People have problems remembering things. Their personality changes and they forget how to do many everyday things. A mental illness charity said dementia would affect 27 per cent of boys and 37 per cent of girls born this year. This could cause a health crisis as everyone gets older. There is no effective treatment to slow down or stop dementia. The charity said governments do more research.
