A universal equation for the shape of an egg
It’ s called oomorphology. Defining pear-shaped eggs used to be a nightmare, but this has now been solved. Mathematicians, engineers, biologists and egg technologists can finally relax…Egg

Volcanic activity and low ocean oxygen events linked to climate
warming and rapid ice melt during last ice age
I have always been fascinated by the potential interactions between atmosphere and lithosphere. The paper shows some large-scale effects; its not only snow melt in Alaska and the resulting changing pressure on the ground that links volcanoes to weather.Glaciers-volcanoes-ocean

Large parts of Europe are warming twice as fast as
the planet on average
Climate results from the interaction of several factors. Aerosol particle concentrations led to cooling in Central and Eastern Europe over the past four decades. But now aerosol reductions result in the April–September period increasing by around 1°C.Europe warms fast

Optical role of diatom shellThe beautiful silica diatom shells serve a purpose beyond protecting the one-celled alga that lives inside: it also increases the light available for photosynthesisDiatom shells
The 2022 Global witchcraft inventoryWitchcraft is the art of remotely affecting other people. You’ ll be surprised to find how many people believe in it. See comments below for an amazing confirmation From the NY Times about Argentinian Football.Witchcraft

2,000-year-old shipwreck
reveals complex trade network
If you need tin to turn soft copper into more resistant bronze, you’ ll go to great lengths to get it. This is what people did thousands of years ago, bringing the metal from central Asia to the Mediterranean.

Rapid warming linked to
leap in tropical seasonality
Climate warming is not so well-behaved as we would like: two warming events around 14,700 and 11,700 years ago had spectacular temperatures jumps by up to 10° C over just a few years to decades. This may be triggered by short-term (seasonal) variations.

Landslide risk remains years after even a
weak earthquake
Based on Italian data, the paper shows that landslides may be long-term consequences of short-lived earthquakes.

Assessing El Nino ‘flavors’ to unravel past
variability, future impact
No two El Nino events are the same. This has been going on for ages… and can help us understand tomorrow’s event.

Eifel Megafauna succumbed to forest increaseIf you think that our Neanderthal or sapiens ancestors ate the last mammoth, think again: it seems that mammoth and bison could not adapt to the forests that developed after glaciers retreated.

Why does life use just 20 amino-acids?4 (5) DNA bases are assembled in 3-letter codons that correspond to one of just 20 amino acids. Why so few? This paper has the beginning of an answer.Only 20 AAs
Simple rules outsmart
“intelligence”
Starting with John Conway’ s Game of life, we have learned that the application of simple rules can often lead to amazingly complex systems. There has been a recent flurry of research on the subject.Original article: Multi-scale organization in communicating active matterSpontaneous complexity
