Charles Darwin discovery unearthed in Copenhagen

As a thank you to his Danish colleague, Charles Darwin sent 77 personally identified crustacean species to the Zoological Museum. At the time, they were merely filed away but today – 160 years later – they represent one of the biggest Darwin collections in the world.

For 160 years it sat unnoticed, but when the Zoological Museum in Copenhagen was preparing a new exhibition it uncovered an unexpected contribution from the father of evolution himself, Charles Darwin. 
 
A collection of 55 jars containing different species of crustaceans that Darwin had borrowed from the Danish museum in 1854 was unearthed by museum officials. Along with the collection was a list written in Darwin’s own hand identifying the species. 
 
The museum thinks that the discovery could represent the most significant Darwin collection outside of London’s Natural History Museum. 
 
According to the museum’s head of exhibitions, Hanne Strager, the list was a gift to Japetus Steenstrup, a Danish researcher who had originally loaned Darwin the crustaceans for his research on evolution and who at that time was head of the Zoological Museum. 
 
Strager made the discovery when preparing for the upcoming exhibition ‘Det Dyrebare’ (Precious Things), the largest exhibition in the museum’s history that will feature items from the museum's archives that are normally hidden away from the public. 
 
Aware of the relationship between Darwin and Steenstrup, Strager began closely examining correspondence between the two men. In one letter sent from Darwin to Steenstrup in 1854, he described a list of 77 species. The list itself, however, could not be found. 
 
“We thought maybe the list would be among Japetus Steenstrup’s papers in our archives, and wouldn’t you know it, there it was,” Strager said in a museum press release. 
 
Strager, who has written a book on Darwin, was immediately able to identify his handwriting. Using the list, her team was able to track down 55 of the 77 species listed by Darwin. 
 
“To be able to display a gift from one of the world’s greatest scientists is something very unique. Here we have a personal relationship to the person who is behind perhaps biology’s single greatest scientific discovery: the theory of evolution,” Strager said. 
 
And just how did this unique collection go unnoticed all these years?
 
“Steenstrup received the gift from Darwin before his book On the Origin of Species was published, putting the theory of evolution on everyone's lips. So rather than keeping the gift’s contents together in one spot, the 77 species were spread out across the museum’s collections. It certainly made good sense at the time, but today we of course would see it differently,”  Strager said. 
 
Strager said the Darwin discovery will be front and centre when the museum’s new exhibition opens on September 1st. It is bound to attract great global interest.
 
“It is very exceptional that here in Denmark we have uncovered a collection from Darwin himself. It will generate international attention and my colleagues over in Cambridge will undoubtedly be very excited about the discovery,” Aarhus University evolutionary biology professor Peter Kjærgaard told Berlingske.

Nobel Prize in Chemistry awarded for ‘ingenious tool for building molecules’

The Royal Swedish Academy of Sciences in Stockholm, responsible for awarding the Nobel Physics and Chemistry Prizes, has announced the winners of the 2021 Nobel Prize in Chemistry.

The prize this year has been awarded to Germany’s Benjamin List and David MacMillan from Scotland, based in the US.

The Nobel Committee stated that the duo were awarded the prize “for their development of a precise new tool for molecular construction: organocatalysis”. The committee further explained that this tool “has had a great impact on pharmaceutical research, and has made chemistry greener”.

Their tool, which they developed independently of each other in 2000, can be used to control and accelerate chemical reactions, exerting a big impact on drugs research. Prior to their work, scientists believed there were only two types of catalysts — metals and enzymes.

The new technique, which relies on small organic molecules and which is called “asymmetric organocatalysis” is widely used in pharmaceuticals, allowing drug makers to streamline the production of medicines for depression and respiratory infections, among others. Organocatalysts allow several steps in a production process to be performed in an unbroken sequence, considerably reducing waste in chemical manufacturing, the Nobel committee at the Royal Swedish Academy of Sciences said.

The Nobel committee gave more information in a press release as to why List and MacMillan were chosen: “Organocatalysis has developed at an astounding speed since 2000. Benjamin List and David MacMillan remain leaders in the field, and have shown that organic catalysts can be used to drive multitudes of chemical reactions. Using these reactions, researchers can now more efficiently construct anything from new pharmaceuticals to molecules that can capture light in solar cells. In this way, organocatalysts are bringing the greatest benefit to humankind.”

List and MacMillan, both 53, will share the 10-million-kronor prize.

“I thought somebody was making a joke. I was sitting at breakfast with my wife,” List told reporters by telephone during a press conference after the prize was announced. In past years, he said his wife has joked that he should keep an eye on his phone for a call from Sweden. “But today we didn’t even make the joke,” List said. “It’s hard to describe what you feel in that moment, but it was a very special moment that I will never forget.”
