Remnants of ‘the eighth wonder of the world’ in a Museum drawer |Curator of Petrology

Some rare treasures are hidden within the Petrology collection of the Natural History Museum, and this brunch of a bush, encrusted with sinter, which formed prior to 1886 around hot springs on the shores of the old Lake Rotomahana (warm lake) in New Zealand, is one of them.

Read on to learn about the Pink and White Terraces, a natural wonder of the world, regarded by the Māori as a taonga (a treasure), their tragic fate and how specimens in the museum collection are helping current research.

Collecting the periodic table’s rarest elements: osmium, rhodium and iridium #IYPT2019

by Richard Herrington, Head of Earth Sciences

At the Natural History Museum our work is based on scientific collecting to support research on the natural world. In our collections we hold naturally occurring chemical elements in many different forms, compounds and combinations, so with many others, we are marking the 150 years since the periodic table was published in 1869 by the Russian chemist Dmitri Mendeleev by celebrating the International Year of the Periodic Table.  We are aiming to cover all of the elements in our collections in a blog, starting with osmium, rhodium and iridium.

Are our collections relevant to modern science? How do we know?

During a conversation with colleagues recently, the topic of “How can we judge that our collections are useful” came up. We can measure the number of visitors into the collections and we can keep tabs on the loans that we send to researchers at different institutes, but is this ever useful. I tasked myself this afternoon to finding out, for just one collection that I care for, just how much our collections are used for relevant science.

For my afternoon task, I chose to use the John Williams Index of Palaeopalynology (JWIP) as my example collection. The JWIP is a database using old-style cards (over 250 000 cards in fact) of the written literature on organic-walled microfossils (spores, pollen and algal cysts are a few such things). Many researchers on these organic-walled microfossils (called palynologists) visit the Museum to look through this resource every year. Read more about this collection https://bit.ly/2BiRtlb

To find out how useful the collection has been for the visiting palynologists, I searched the internet for all of the published scientific papers that acknowledge/cite the JWIP. To my surprise, there were many more articles than I was expecting in the last 10 years alone. Twenty-three scientific papers and three PhD theses (there is also another from 2003 that appears on the first page of the search engine) have presented data that they found using the JWIP. There are possibly more that I have yet to find or have not acknowledged the data (Please researchers, acknowledge where your data comes from!). The current list of publications citing JWIP can be found by clicking here

The research in these publications is quite varied. They range from climate change through the Cenozoic Era to diversity changes over extinction events to understanding new species concepts in some of the oldest organic-walled fossil groups.

This is timely as a piece of work has just been published in the journal Nature Communications by Dr. Hendrik Nowak and his colleagues on the greatest extinction event of all time – the Permian/Triassic mass extinction ~250 million years ago. This study uses extensive data collected during a two-week visit that Hendrik had to the JWIP in 2017. You can read about his work in this blog

Simply acknowledging museum collections might not be on the front of all researchers’ minds, but it does help advocate the use of these important scientific materials. It is fantastic to see that in the last ~10 years, one of our collections has contributed so much and that people have felt the need, without pressure to do so, to acknowledge the resource.

We are trying to put as much information about our collections online, so that researchers understand more about what there really is to study here. Hopefully, this will be a positive step in making even more use of the museum and its incredibly vast resources.

New study shows the value of historical sediment collections | Curator of Micropalaeontology

A study published this week in Frontiers of Ocean Science based on our Ocean Bottom Deposits Collection has shown the value of  historical sediment collections to provide a benchmark to assess global changes in the seafloor environment.

Read on to find out how NHM/Southampton PhD student Marina Rillo used the microfossil content of these collections to develop a method to assess their usefulness in providing details of the state of the ocean floor as long as 150 years ago.

The mystery of the microfossil Christmas cards | Curator of Micropaleontology

At this time of year our famous microfossil Christmas card slides always get a lot of attention. An article in Smithsonian Magazine this week followed a very popular Tweet in early December and perhaps the most famous of the slides is about to be displayed in Museum’s Touring Treasures exhibition in Bahrain in early 2019.

This year, three additional Christmas greeting slides were added to our collection as part of an exceptionally generous donation by the Quekett Microscopical Club. They returned Arthur Earland’s foraminiferal collection to its place alongside long term collaborator Edward Heron-Allen’s collection at the Museum by purchasing the collection from the estate of Brian Davidson and donating it to the Museum.

Read on to find out why most of this new acquisition can be considered upside-down, contains more evidence of the two scientists falling out and the mystery of the three “new” Christmas greeting slides.

Trying something new – building the Life in the Dark interactive splash | Digital Media at the NHM

http://www.nhm.ac.uk/visit/exhibitions/life-in-the-dark.html

As part of the museum’s Life in the Dark exhibition digital content offer, we decided to try something new for our exhibition landing page to help promote interest and engagement.  We ended up using a new mix of front end technologies to build it, so here’s a (long) technical walk through of the various challenges and solutions we encountered.
