‘Turning point’: claw print fossils found in Australia rewrite story of amniotes by 40 million years

The discovery by two local fossil hunters on a river bank in Victoria has ‘potentially far-reaching implications’, scientists say

Fossilised claw prints found in Australia suggest amniotes – the ancestors of reptiles, birds and mammals – evolved about 40m years earlier than thought.

The footprints, in sandstone dated 354m to 358m years old, were probably made by reptiles crossing a surface dimpled by raindrops. Researchers said the trackways represent the oldest evidence of amniotes on the planet.

Cornish tin was sold all over Europe 3,000 years ago, say archaeologists

British team says new study ‘radically transforms’ understanding of bronze age trade networks

In about 1300BC, the major civilisations of the eastern Mediterranean made a cultural and technological leap forward when they began using bronze much more widely for weapons, tools and jewellery. While a form of the metal had previously been used in smaller quantities by the Mycenaeans and Egyptians among others, bronze was now abundant – but how?

Most bronze is an alloy of copper and tin, but while the former was widely available in antiquity, tin is a rare element, with no large sources within thousands of kilometres. This left one big question, referred to by archaeologists as the “tin problem”. Where were the bronze age societies of the Mediterranean getting the tin for their bronze?

‘A win-win for farmers’: how flooding fields in north-west England could boost crops

A ‘wetter farming’ project explores rehydrating peatland to help grow crops in boggier conditions while cutting CO2 emissions

“I really don’t like the word ‘paludiculture’ – most people have no idea what it means,” Sarah Johnson says. “I prefer the term ‘wetter farming’.”

The word might be baffling, but the concept is simple: paludiculture is the use of wet peatlands for agriculture, a practice that goes back centuries in the UK, including growing reeds for thatching roofs.

Drinking champagne could reduce risk of sudden cardiac arrest, study suggests

Maintaining a positive mood and eating more fruit may also help lower risk, researchers find

Drinking champagne, eating more fruit, staying slim and maintaining a positive outlook on life could help reduce the risk of a sudden cardiac arrest, the world’s first study of its kind suggests.

Millions of people worldwide die every year after experiencing a sudden cardiac arrest (SCA), when the heart stops pumping blood around the body without warning. They are caused by a dangerous abnormal heart rhythm, when the electrical system in the heart is not working properly. Without immediate treatment such as CPR, those affected will die.
