The glow of one warm thought is to me worth more than money.
Sex? It all started 385 million years ago
It may not have been love as we know it, but around 385 million years ago, our very distant ancestors—armoured fish called placoderms—developed the art of intercourse.
So suggest a team of evolutionary scientists, who point to the fossil of a placoderm species blessed with the name of Microbrachius dicki.
Measuring about eight centimetres (four inches) in length, M. dicki lived in habitats in modern-day Scotland—where the first specimen was found in 1888—and in Estonia and China.
Placoderms have previously been found to be the most primitive jawed animal—the earliest known vertebrate forerunner of humans.But they now have an even more honoured…

A little Doctor Who tribute
Earls Court, London, 2014
So I am secretly a massive geek - I’ve loved Doctor Who since I was scared by ‘The Awakening’ (featuring a scary alien face in a wall!) in 1983 - one of my earliest memories as I was only 3! The show fired my imagination from an early age. So I made this the other day in a little nod to tomorrow’s episode, Flatline…. (You’ll have to watch to see why - I couldn’t resist!)
The police box featured is one of the few still around on the streets, you can see it right outside of Earls Court tube station.

[…] Só uma coisa a favor de mim eu posso dizer: nunca feri de propósito. E também me dói quando percebo que feri. Mas tantos defeitos tenho. Sou inquieta, ciumenta, áspera, desesperançosa. Embora amor dentro de mim eu tenha. Só que não sei usar amor: às vezes parecem farpas.
What Causes Brazil’s ‘Meeting of the Waters’?
by Bec Crew
This is what it looks like when the Solimões River meets the Rio Negro in Brazil.
Almost 10 kilometres from the inland city of Manaus in northern Brazil, ‘the Meeting of the Waters’ is the point where two of Amazon River’s largest tributaries - a smaller river that flows into a bigger ‘parent’ river - converge but never mix.
The Solimões River forms the lighter half, its ‘cafe au lait’ colouring owed to the rich sediment that runs down from the Andes Mountains, including sand, mud and silt. Known as a ‘white water river’, the Solimões River stretches over a 1600 km distance.
The darker side is the Rio Negro, and it gets its ‘black tea’ hue from leaf and plant matter that has decayed and dissolved in the water. It might look dark and murky, but the Rio Negro carries little or no sediment, and according to the European Space Agency website, is considered one of the cleanest natural waters in the world. On really clear days, water visibility in this black water river can exceed nine metres. ..
