New species of 2016
2016 has been an absolutely shait year, so I am not going to do a list of main events. I think we better get seriously drunk and forget the sorry business. However! As every year, new species are discovered, and not all of them tiny bacteria, gray mushrooms, or minuscule fish from lake Malawi. I ...

iNaturalist: citizen science in your backyard
I was going to write an article about the Encyclopedia of Life. It is a phenomenal undertaking, its goal is to create one web page for every living species. Right now they have 1,322,989 pages. That is 1.3 million living things. It is a herculean effort, and it takes the biggest institutions and the best ...

Are Smart Contact Lenses Here to Efface Privacy?
The patent is 29 pages long and all in Korean. That might the reason why Samsung's Smart Contact Lenses went unnoticed for several years. Now, it's out. The product, from the get go, is a potential privacy nightmare. The lenses are equipped with a camera, display, an antenna, and sensors (the actual processing operations happen ...

Biotech: future of digital storage is plant DNA
If you have a garden and a library, you have everything you need.– Marcus Tullius Cicero Now the garden can be the library. Researchers at the University Medical Centre Maribor, Slovenia have encoded digital information into plant DNA. So what? you might ask. Oh; it is wild: in a box of seeds, you could have all knowledge ...

Axolotl – the salamander that never is
Axolotl. Ambystoma mexicanum. What is it? It belongs to the salamanders, but. A salamander is a creature that has some properties and life history. Your garden-variety salamander starts life as an egg, larvae, tadpole, metamorphosis, adult salamander. After metamorphosis the creature is an adult, crawls up on land and reproduce. That is the idea. But there ...

Luidia sarsi: sea star magic
Luidia sarsi. mer-littoral.org Here you are, minding your own business, and you come across a sea star (marine biologists will stab you in the hand with a fork for calling it a starfish). An orangy-white, five-armed rather unremarkable fellow, you might think. And you would be so, soooo wrong. Luidia sarsi turns sexual reproduction upside ...

Blasphemous Theories About the First Americans
The ice bridge through which the first American settlers came from Asia was neither made of ice nor a bridge. And according to new evidence, it might have not been the only way in which the continent was populated. Previously dismissed blasphemous theories about the first Americans are enjoying a come-back, and it's finally time ...

A creationist’s toybox: The Acámbaro figures
In July 1944, a German merchant named Waldemar Julsrud announced he had discovered several thousands ceramic figurines in Mexico, representing everything from supposed dinosaurs to peoples from all over the world. Julsrud had an impressive collection: Over 32,000 original pieces. You can see a few of them here: When I read about this story, I was instantly ...

Celebration of Snails
This article title is absolutely on point. About a year ago, I started a post but just filled in the headline. Naturally, I completely forgot about it until Bente asked me about the draft. What I didn't tell her was that by then I had no idea what the original intention had been, but I was pretty sure it wasn't ...

Gorgeous ammonites
Ammonites are amongst the most popular fossil, and they have every right to do so. These beautiful spiral creatures are somewhat related to octupuses and squids, the only difference being that they went extinct 75 million years ago, along with the dinosaurs. When ammonites originated, they were planktonic and tiny. Less than 1mm tiny. As they ...

Human Evolution Infographic
I made this infographic to show the (current state of things for) human evolution. Or quite current, because there have been some new discoveries, but they are still being debated. Feel free to download, distribute and change it, but please don't crop my name off it as it took me a long time to make it! Licence ...

Ultraviolet Flowers, Infrared Trees
As humans, we have a very reduced visual spectrum. We can only catch light within certain frequencies, as Newton demonstrated this by dividing light using a prism (a beam of light contains the colors of the rainbow, because colours are wavelengths - the longer wave we can see is red, followed by orange, yellow, green, cyan, blue, and violet, the shortest wave. Whatever falls outside ...

Games that do science
When the internet was fairly new, a project without precedent set itself to push the limits of what seemed then inconceivable for both science and technology. It was called SETI@Home, and it marked the beginning of a completely new era. SETI's goal was to detect intelligent life outside Earth. To do so, the project collected a ...

My geologic timeline in the magazine Science & Vie!
A long time ago I made a geologic timeline as a (vector) brush in Illustrator, with .ai and .eps files free for anyone to use. The only thing I ask is that if you use it, let me see the result. Making the timeline was incredibly time-consuming and ludicrously fiddly. So, a while ago I got ...

Sensory homonculus
Sensory homonculus: of all nonsensical stuff I have made, this sensory homonculus is up there. Stoneware clay, watercolour, acrylic paint. Sensory homonculus Sensory homonculus Sensory homonculus Sensory homonculus Sensory homonculus Sensory homonculus Sensory homonculus Sensory homonculus ...

Thomassons: extinct architecture
The 99% invisible is a brilliant podcast. I was alerted to the so-called Thomassons. These are architectural artefacts who have lost their function, but, and this is crucial: are still being maintained. For – essentially – no reason whatsoever. It is surprisingly hard to find images that exemplifies it. What I find fascinating, is the ...

You know you want one: science nerd merit badges
Out of the generosity of the Order of the Science Scouts of Exemplary Repute and Above Average Physique I have been allowed to recreate their science nerd merit badges. You can find the indexed list here, or you can go directly to my Cafépress profile. No, this will not in any way make me rich and/or famous, ...

Dress to impress: Sexual selection and birds of paradise
There are an estimated 42 species of bird of paradise in New Guinea, and they all look completely different. Females choose mates based on the condition and colour of the males’ plumage, so males puff their feathers, vibrate and buzz to attract their attention. Some even transform their bodies into strange, geometrical abstractions. If successful, these aesthetically ...

Visualizing DNA
When I was doing my Thesis (population genetics, migration), I spent a fair amount of time extracting DNA from blood samples. The process was fascinating, and a little demanding - precise pipette handling can leave your shoulders in misery! Anyhow, it took us two days to get 'pure' DNA from a blood sample, and day II was always my ...

There is grandeur in this view of life – visualising Darwin
If I were to give an award for the single best idea anyone has ever had, I had to have to give it to Darwin, ahead of Newton and Einstein and everyone else. It is not just a wonderful scientific idea; it is a dangerous idea. it overthrows, or at least unsettles, some of the ...

Prehistoric Art: The Upper Paleolithic Revolution
Yisela The Upper Paleolithic or Late Stone Age begins and ends with a revolution. The first one is what can be considered the 'official' appearance of art, some 50,000 years ago. The second, the invention of agriculture, 40,000 years later. The earliest sample of Paleolithic art is the shells with holes and chipped edge modifications from Ksar Akil. These flakes show regular teeth distributed ...

Chickenosaurus
Jack Horner is a paleo-dude of the purest water. He is funny, knowledgeable and loves dinosaurs so much he wants to build one. And it is actually feasible. Chickens are basically altered dinosaurs, and fiddling with switching on and off genes will give you a chickenosaurus. See the TED talk. Best dude around ...

Living evolution: archaeopteryx, pterodactyl, hoatzin
pterodactyl Archaeopteryx Hoatzin bird I am going to skip over the arguments against the imbeciles who believe that the world is 6000 years old. Richard Dawkins are nobly taking that task upon himself. About 150 million years ago, the pterodactyl roamed the skies (pterodaktulos, meaning "winged finger"). There is something about that shape (and size!) ...

Ernst Haeckel: art and science through the microscope
Ernst Haeckel Ernst Haeckel (1834 – 1919) was what we call a renaissance man. He was a professor, biologist, philosopher, physician, naturalist and artist. His contribution to biology, evolutionary theory and art is still mind-boggling; we owe a great deal of biological understanding and terminology to him. He was a great promoter of Darwin's theory ...

Animal, vegetable, mineral, man-made
The three kingdoms, according to Linnaeus; was mineral, vegetable, animal. Throw in man-made, and you have the Natural and the Artificial worlds… ...
