Stress really does turn your hair grey

 

Watch:https://www.youtube.com/watch?v=IYabQyOCqlE

Scientists have discovered that stress is one factor in turning our hair grey, white or silver - at least, in mice. Stem cell biologists from Harvard University in the USA conducted a series of tests on mice to ascertain the effects of stress on the rodents. The scientists injected the mice with an ingredient found in chili peppers that gives them their heat. The compound made the mice stressed. This caused a hair-colouring pigment in the mice to go into overdrive as a reaction to the stress and deplete colour-regenerating stem cells. This caused the mice's hair to rapidly turn white. Lead researcher, Professor Ya-Chieh Hsu, said: "The detrimental impact of stress that we discovered was beyond what I imagined."

People have wondered for centuries about the link between stress and greying hair. It is believed that France's Queen Marie Antoinette's hair turned white the night before she was beheaded during the French Revolution in the late-eighteenth century. More recently, we have witnessed the locks of presidents and other world leaders quickly lose colour. The strains of leadership seem to go to the roots of things, especially hair follicles. Professor Hsu said the loss of the pigment-regenerating stem cells cannot be reversed. She said: "Once they're gone, you can't regenerate pigment any more. The damage is permanent." Worryingly, she hypothesised that stress could be responsible for hastening the aging process.

NOTE: It may seem difficult to remember that “t” is sometimes spoken and sometimes silent. However, one of the main reasons the “t” is sometimes silent has to do with how difficult it would be to properly pronounce the word if the “t” needed to be enunciated. If it would be awkward to form the sound of the word if the “t” needed to be pronounced, chances are that’s a word where the “t” should (or can) be silent.

Also some words like Ballet and Gourment come from French and in that language when a word ends with a T , it is usually silent.

Electric-car battery charges in five minutes

  Electric-car battery charges in five minutes     watch:   https://www.youtube.com/watch?v=-U1a2UOVs3M Car makers are spending a lot of money on electric cars. In the future, electric cars will replace petrol cars. Environmentalists believe this will reduce the amount of CO2 put into the atmosphere. A big problem for electric cars is charging the battery. Some batteries in today's electric cars can take up to 12 hours to charge fully. However, a company in Israel says it has created a lithium-ion battery that people can charge in just five minutes. This is the same amount of time it takes to fill a tank of gas with petrol. The new lithium-ion batteries were developed by the Israeli company StoreDot. They are being manufactured by a Chinese company called Eve Energy. The new batteries could totally transform driving. They would mean electric cars would be able to travel as far as petrol cars. Many people with electric cars today suffer from "range anxiety". This ...

EU angers UK by calling Gibraltar a 'colony'

Watch:    https://www.youtube.com/watch?v=HfrWWQ4Kfy8   The United Kingdom has objected to the European Union's use of the word "colony" to describe the island of Gibraltar. The European Council (a body that defines the EU's political direction) produced a document regarding UK nationals travelling to the EU after Brexit. It says in a footnote: "Gibraltar is a colony of the British Crown. There is a controversy between Spain and the UK concerning the sovereignty over Gibraltar, a territory for which a solution has to be reached." A UK government spokesperson said: "Gibraltar is not a colony and it is completely inappropriate to describe it in this way. She added: "Gibraltar is a full part of the UK family....This will not change due to our exit from the EU." Gibraltar is a British Overseas Territory located in the Mediterranean Sea between Spain and Morocco. It is home to over 30,000 people. In 1704, Anglo-Dutch forces captured it from Spa...

Chimpanzees love dancing, say researchers

  Chimpanzees love dancing, say researchers   Who knew that chimpanzees love to dance? They also like to clap along to music, and nod their head, tap their feet and move in time with the rhythm. A new study shows that chimpanzees could appreciate music. The researchers are from Kyoto University in Japan. They say their study could help us understand how early humans developed an interest in music. Researchers Dr Yuko Hattori and professor Masaki Tomonaga conducted tests on seven chimps. They played the apes six two-minute songs on a piano for six days. The researchers said the chimps had a definite sense of rhythm and it changed their mood. The male chimpanzees seemed to respond to the melodies more than the females. The researchers wrote that chimpanzees could have passed on a liking for music and dance to early humans millions of years ago. This could have happened via a common ancestor around six million years ago. The researchers said the study suggested that our love...
