Grandma, what a big brain you have!

All the better to survive with, my dear

Sit down with a prehistoric relative of ours from the genus Homo - their extinction making it a lot easier said than done - and you’ll notice something significantly different: their heads, and therefore brains, are a fraction of the size of a modern human’s. Why exactly did brain size increase? Quite simply, large and complex brains can process and store more information, which was hugely beneficial to humans as they developed skills and social interaction.

The Smithsonian NMNH Human Origins exhibit houses a collection of fossil skull remnants dating back as far as 3 million years ago, as well as silicon reconstructions of early humans. One can see a gradual change in facial features, body hair and most significantly, head shape and size. Over the course of human evolution, it’s found that brain size tripled, with the modern human brain being the largest and most complex of any living primate. But, size alone doesn't tell us much about thinking ability.

Here’s a bit of what we know. 

Networking a Cure for HIV

The human immunodeficiency virus (HIV) is an enigma of an infection that has puzzled scientists, doctors, and researchers since the first presented case in the 1980s. Although the modern medical community continues to study it and gather information, a cure for the disease remains elusive. According to the Elizabeth Glaser Pediatric AIDS Foundation, as of 2015, there are nearly 37 million people worldwide who have been infected by HIV. Of that number, 1.8 million are children under the age of 15. In 2015, approximately 150,000 children were newly infected with HIV - a rate of nearly 400 new pediatric HIV patients every day. These numbers present a huge problem that appears to grow threateningly larger in the face of the lack of a cure for the disease.

Scientific Collections vs. Pandemics: an unfair match?

Sweeping across three countries and claiming over 11,000 lives, the 2014 West African Ebola outbreak is almost impossible to forget. First identified in 1976, in a remote village named Zaire in what is now the Democratic Republic of Congo, there have been multiple outbreaks of the virus since. But the 2014 pandemic, caused by the Zaire strain, has been the most deadly. Striking on the border of three of the poorest African nations, Sierra Leone, Guinea and Liberia, the virus spread to an unprecedented scale. Liberia, the worst hit, was not officially declared Ebola-free until the 13^th of January 2016.

Could it have been stopped quicker? That’s where scientific collections come in.
