In the forests of Costa Rica, a tiny insect has been found. Tinkerbella nana is a fairyfly that is only 250 micrometers long. It is one of the smallest arthropods ever discovered.

How could they even find such a tiny creature? The researchers admit that it was not easy given the biodiversity of the forest. “It is possibly equivalent to finding a solitary needle in 200 haystacks,” Dr John Noyes notes.

Ancient baby's teeth have revealed that Neanderthals followed today's breastfeeding guidelines. Scientists analyzed a fossilized baby tooth from a Neanderthal child, and found the infant was breastfed exclusively for the first seven months of life and given supplementary foods and mother's milk for another seven months before being weaned.

This fascinating discovery sheds light on the remarkable similarities between Neanderthal parenting practices and contemporary breastfeeding guidelines. By examining the composition of the fossilized baby tooth, scientists have uncovered valuable insights into the dietary patterns of our ancient relatives.

The Neanderthal infant's exclusive breastfeeding for the first seven months of life mirrors the advice ...

Schizophrenia has a variety of causes and a spectrum of severity of symptoms. Geneticists were able to cause schizophrenia-like symptoms by over-expressing Neuregulin-1 (NRG1). Scientists discovered that these mice not only had nearly the same symptoms as humans with schizophrenia, but they even develop the symptoms at the same stage in life. Geneticists have been able to modify the expression of NRG1 in adult mice, bringing it down to appropriate levels. This caused schizophrenia-like symptoms in these mice to disappear and behavior returned to normal. ...

This is the Great Blue Hole of Belize in Central America, and at 300 metres across and 124 m deep, it's thought to be the largest submarine cave on Earth. It was first discovered by French explorer Jacques Cousteau, and was formed over a period of around 140,000 years when the sea levels were much lower than they are now. As the sea levels rose, a number of limestone caves were flooded over time to create this almost perfect circle. It's now home to several species of fish and reef shark. ...

In the Amazon rainforest salt is a highly sought after commodity. Tears are full of salt, so these butterflies are literally drinking the turtles tears to get the vital mineral.

This is a fairly common sight in the Amazon, and it's not restricted to butterflies.

Makes sense, doesn't it?
