Louis Pasteur’s scientific discoveries in the 19th century revolutionized medicine and continue to save the lives of millions today On World Rabies Day – which is also the anniversary of French microbiologist Louis Pasteur’s death – a virologist reflects on the achievements of this visionary scientist.

What do you know about Louis Pasteur who developed the first effective rabies vaccine back in 1885?

One of the most brilliant minds and scientists of all time, writes Rodney E. Rohde. Pasteur died on this day in 1995, and #WorldRabiesDay is marked on the anniversary.

Yunxian 2, is that you?! 💀

I’m sure they’re fondly remembering a previous joke

First day of my lecture course on the evolution of human technology, and my students just voted to have a laptop-free class. Sometimes, all is right with the world.

Experimental evidence for the efficacy of transversal hafting of backed segments as arrowheads Backed segments in quartz from the Howiesons Poort industry of Southern Africa (65–60 ka) have been interpreted as tips of arrows. Nevertheless, sever…

Prehistoric stone tools were often hafted, but we only find the lithics not the wood/bone part of tools. So it is not always clear how stones were hafted.

We tested two ways of hafting the same type of arrow tip, shooting into ballistics gel. Very mythbusters!

78,000-year-old footprints from Neanderthal man, child and toddler discovered on beach in Portugal A Neanderthal trackway discovered in Portugal shows how an adult male and two children hunted for food 78,000 years ago.

"It was early in the morning of a sunny day, with perfect light for checking tracks," Neto de Carvalho told Live Science in an email. 🏺🧪

Molecular analysis of a hominin mandible from Taiwan reveals the lineage and sex of the individual.

A fossil Pleistocene-age hominin jawbone discovered in Taiwan has now been identified as belonging to a Denisovan, finds a new study in Science.

The results provide direct molecular evidence that Denisovans occupied diverse climates and offer new insights into this hominin lineage. scim.ag/4joSUBh

How evolution favoured costly and frivolous animal play | Aeon Essays Here’s a puzzle: how could evolution favour such a costly, frivolous and fun activity as animal play?

I am very happy to share this piece with you, exploring the link between inventiveness and play in nonhuman animals. It was written with care and a sincere desire to convey what science and philosophy can teach us about this fascinating topic.
I hope you enjoy reading it!

Leslie White (1942) on human tool use. Simply breathtaking.

So pumped to announce this fabulous conspiracy-in-progress 📖

Strategy and Ideology through ZooMS: Insights from Palaeolithic and prehistoric bone tools ZooMS (Zooarchaeoology by Mass Spectrometry) is a biomolecular technique for determining the taxon of origin for archaeological bone and osseous tool …

Tools - as manifestations of human strategic thinking - can tell us a lot about the people that made them. My new paper (out today!) offers some interpretive frameworks for ancient bone tool analysis.

Honored to announce I’m writing a book! We understand the importance of stone tools in the Stone Age. But what about socks? Rope? Water bottles? Boats? How did we go from knocking rocks together to the Saturn V rocket? This work takes a long view perspective on how the things we make, make us.

Learned magnetic map cues and two mechanisms of magnetoreception in turtles - Nature Loggerhead sea turtles, which undergo long-distance migrations, can learn magnetic signatures associated with different geographic areas and have two different magnetic senses, each based on a different underlying mechanism.

A paper in Nature reports that the loggerhead turtle can learn and remember the magnetic signature of an area and does a ‘turtle dance’ when in a location that they associate with food. https://go.nature.com/4jSQEDo 🐢 🧪

Does a scientific understanding of our world conflict with the marvelous wonder we experience in it?

In a word: No.
