Male dolphins form lifelong bonds that help them find mates, research finds

Leave a Comment / Science / By

Dolphins form decade-long social bonds, and cooperate among and between cliques, to help one another find mates and fight off competitors, new research has found – behaviour not previously confirmed among animals. “These dolphins have long-term stable alliances, and they have intergroup alliances. Alliances of alliances of alliances, really,” said Dr Richard Connor, a behavioural …

Even if the entire world stopped burning fossil fuels today, a new study finds the Greenland ice sheet would still lose enough ice to add nearly a foot to rising sea levels. Melting over the past century has altered the ice sheet’s equilibrium, according to the study led by two glaciologists at the National Geological Survey of Denmark and Greenland. For …

Mummified, spread-eagled Triassic ‘shovel lizards’ look like roadkill and likely died in a drought

Leave a Comment / Science / By

About 251 million years ago, groups of pig-size herbivores with tusks and beaks huddled together, died, shriveled up and then fossilized looking like squashed roadkill, with impressions of their pebbly skin still present in the rocks around them.  These strange layers of fossils suggest that recurring drought was a big problem for the animals, which …

Dark energy remains a mystery as Einstein’s theory of gravity passes another test

Leave a Comment / Science / By

Scientists are still coming up empty in the hunt for flaws in Einstein’s theory of general relativity that could explain the mysterious force driving the accelerating expansion of the universe.  The researchers studied 100 million galaxies looking for signs that the strength of gravity has varied throughout the universe’s history or over vast cosmic distances. …
