Sequencing the genome of the leopard
They are some of the most beautiful, and elusive, animals on the plant. Leopards. In a major scientific step, the whole genome DNA sequence of 23 individual leopards have been interpreted. These majestic animals are the only great cat species (Genus Panthera) to roam about both Africa and Asia today. Leopards are considered as highly…

Simulated deep-sea mining affects ecosystem functions at the seafloor
The environmental impact of deep-sea mining is only partially known. Also, there is a lack of standards to regulate mining and set binding thresholds for the impact on the local organisms. Researchers have now determined that deep-sea mining-related disturbances have a long-term impact on the natural ecosystem functions and microbial communities at the seafloor. What…

From Earth’s deep mantle, scientists find a new way volcanoes form
Far below Bermuda’s pink sand beaches and turquoise tides, geoscientists have discovered the first direct evidence that material from deep within Earth’s mantle transition zone — a layer rich in water, crystals and melted rock — can percolate to the surface to form volcanoes. Scientists have long known that volcanoes form when tectonic plates (traveling…

Global study reveals time running out for many soils, but conservation measures can help
Researchers found more than 90 per cent of the conventionally farmed soils in their global study were thinning, and 16 per cent had lifespans of less than a century. These rapidly thinning soils were found all over the world, including countries such as Australia, China, the UK, and the USA. The study, led by Lancaster…

Bronze Age farmers gave preferential treatment to cows over domesticated sheep, goats
Meat and dairy played a more significant role in human diets in Bronze Age China than previously thought. A new analysis also suggests that farmers and herders tended to sheep and goats differently than they did their cows, unlike in other parts of the world — keeping cows closer to home and feeding them the…

Researchers reveal how to turn a global warming liability into a profitable food security solution
Methane, a powerful greenhouse gas, can be captured and transformed into protein-rich feed for farmed fish — an increasingly important food sector. A new analysis shows how to make the approach more cost-effective than current fish feeds. «Industrial sources in the U.S. are emitting a truly staggering amount of methane, which is uneconomical to capture…

Importance of teaching children about environmental issues
Environmental education provision needs greater investment and innovation if future generations are to be able to respond fully to the climate emergency, experts have said. The deepening environmental crisis will continue to worsen if there is not significant support and investment in environmental and science education, researchers have warned. Reforms would help young people to…

No link between milk and increased cholesterol according to new study of 2 million people
Regular consumption of milk is not associated with increased levels of cholesterol, according to new research of nearly 2 million people. A study published in the International Journal of Obesity looked at three large population studies and found that people who regularly drank high amounts of milk had lower levels of both good and bad…

The ripple factor: Economic losses from weather extremes can amplify each other across the world
Weather extremes can cause economic ripples along our supply chains. If they occur at roughly the same time the ripples start interacting and can amplify even if they occur at completely different places around the world, a new study shows. The resulting economic losses are greater than the sum of the initial events, the researchers…

Humans were apex predators for two million years, study finds
In a new study, researchers were able to reconstruct the nutrition of stone-age humans. The study’s authors collected about 25 lines of evidence from about 400 scientific papers from different scientific disciplines, dealing with the focal question: Were stone-age humans specialized carnivores or were they generalist omnivores? «So far, attempts to reconstruct the diet of…
