Can seabirds hear their way across the ocean? Our research suggests so - Lemmy.World

There has been a lot of research into how seabirds choose their flight paths and find food. They seem to use their sight or sense of smell to assess local conditions. Wandering albatrosses can travel more than 10,000km in a single foraging trip, though, and we don’t know much about how these birds use mid- and long-range cues from their environment to decide where to go. For the first time, however, my team’s recent study gives an insight into how birds such as wandering albatrosses may use sound to determine what conditions are like further away.

Many prehistoric handprints show a finger missing. What if this was not accidental? - Lemmy.World

Men and women might have had their fingers deliberately chopped off during religious rituals in prehistoric times, according to a new interpretation of palaeolithic cave art. In a paper presented at a recent meeting of the European Society for Human Evolution, researchers point to 25,000-year-old paintings in France and Spain that depict silhouettes of hands. On more than 200 of these prints, the hands lack at least one digit. In some cases, only a single upper segment is missing; in others, several fingers are gone. In the past, this absence of digits was attributed to artistic licence by the cave-painting creators or to ancient people’s real-life medical problems, including frostbite. But scientists led by archaeologist Prof Mark Collard of Simon Fraser University in Vancouver say the truth may be far more gruesome. “There is compelling evidence that these people may have had their fingers amputated deliberately in rituals intended to elicit help from supernatural entities,” said Collard.

The faith leaders fighting for the climate: ‘we have a moral obligation’ - Lemmy.World

It has been another catastrophic climate year: record-breaking wildfires across Canada scorched an area the size North Dakota, unprecedented rainfall in Libya left thousands dead and displaced, while heat deaths surged in Arizona and severe drought in the Amazon is threatening Indigenous communities and ecosystems. The science is clear: we must phase out fossil fuels – fast. But time is running out, and as the climate crisis, biodiversity loss and environmental degradation worsen, there is mounting recognition that our political and industry leaders are failing us. If the science isn’t enough, what role could – or should – faith leaders play in tackling the climate crisis? After all, it is also a spiritual and moral crisis that threatens God’s creation, according to many religious teachings. Globally, 6 billion people – about 80% of the world’s population – identify with a faith or religion, while half of all schools and 40% of health facilities in some countries are owned or operated by faith groups. In addition, faith-related institutions own almost 8% of the total habitable land surface – and constitute the world’s third largest group of financial investors.
