Every now and then, a revolutionary technological advance comes along and changes the way we live. Li-Fi might just be the next one. Thanks to Prof Harald Haas from the University of Edinburgh, who has demonstrated that by modulating light in an LED bulb, data can be transmitted at a speed 100 times faster than Wi-Fi.
The technology, which could be commercially available in three to four years, will enable us to outfit our offices, malls or bus stations – just about anywhere that has lights – with LED bulbs that send and receive data and provide illumination at the same time. Li-Fi would also be more secure as light can’t penetrate walls, meaning your neighbours won’t be able to steal your bandwidth or eavesdrop on your communications.
The development comes as we mark another milestone in science – the centenary of Einstein’s theory of general relativity that showed how light was at the centre of the structure of space and time. It’s a reminder of the distance we have travelled in 100 years.

Some of Darwish's last words
"They see their tomorrows slipping out of their reach. And though it seems to them that everything outside this reality is heaven, yet they do not want to go to that heaven. They stay, because they are afflicted with hope." - Mahmoud Darwish, to attendees of the Palestine Festival of Literature, 2008
His life in brief: Born in a village near Galilee, he lived in exile for most of his life and started writing poetry after high school. He was arrested several times by Israel for what were deemed to be inciteful poems. Most of his work focused on the love and yearning for his homeland, and he was regarded the Palestinian poet of resistance. Over the course of his life, he published more than 30 poetry collections and books of prose, with his work translated into more than 20 languages. Many of his poems were set to music by Arab composers, most significantly Marcel Khalife. Darwish died on August 9, 2008 after undergoing heart surgery in the United States. He was later buried in Ramallah where a shrine was erected in his honour.

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.
