This Bizarre Illusion Makes Dots In Plain View Disappear | IFLScience

Fancy messing with your senses? Stare at the flashing green dot in the middle of the animation below, and see if you notice anything untoward. If you stare at the green speck long enough, the three surrounding yellow dots will disappear. This is a phenomenon called “motion-induced blindness” (MIB), a form of illusion that causes a person to lose sight of objects that are otherwise in plain view. Although this may appear to be a failing of your own brain’s visual system, fret not: It is merely a way of filtering out excess information.

Bagrawiyah, Sudan – More than 200km from the Sudanese capital Khartoum, the remains of an ancient city rise from the arid and inhospitable terrain like a science-fiction film set. Nestled between sand dunes, the secluded pyramids seem to have been forgotten by the modern world, with no nearby restaurants or hotels to cater to tourists.

The Nubian Meroe pyramids, much smaller but just as impressive as the more famous Egyptian ones, are found on the east bank of the Nile river, near a group of villages called Bagrawiyah. The pyramids get their name from the ancient city of Meroe, the capital of the Kingdom of Kush, an ancient African kingdom situated in what is now the Republic of Sudan.

Around 1000 BCE, after the fall of the 24th Egyptian dynasty, the Nubian Kingdom of Kush arose as the leading power in the middle Nile region. The Kushite kings took over and ruled much of Egypt from 712 to 657 BCE. In 300 BCE, when the capital and royal burial ground of the kingdom moved to the Meroe region, the pharaonic tradition of building pyramids to encapsulate the tombs of rulers continued here.

Royal pyramids were built in Nubia approximately 800 years after the Egyptians stopped building their pyramids. More than 50 ancient pyramids and royal tombs rise out of the desert sands at Meroe. [Sorin Furcoi/Al Jazeera]

Abdullah is from Al Tarabil village, a few kilometres from the ancient burial site. 'This is our history. Here our ancestors are buried. We pay no tax for working here, but there aren't too many people coming to visit lately,' he said. In a good day he makes $10 to $16 offering tourists camel rides. [Sorin Furcoi/Al Jazeera]

Expresso | Ramos-Horta: “Fui contra a declaração unilateral da independência!” ( curiosamente surge lá o meu nome…)

A 28 de novembro de 1975 a Fretilin declarou unilateralmente a independência de Timor-Leste. Nove dias depois, a ex-colónia portuguesa foi invadida pela Indonésia, para uma brutal ocupação que se prolongou até ao histórico referendo de 1999. 40 anos depois da bandeira de Portugal ter sido arriada de Díli, o Expresso entrevistou em Lisboa o Nobel da Paz, José Ramos-Horta, que foi primeiro-ministro e Presidente da República de Timor-Leste
