Space travel can hurt astronauts’ eye nerves Tissues that surround part of astronauts’ optic nerves become damaged due to long-term space travel. The study looked at 15 astronauts who had been in space for about six months. Live Science Evidence that world’s freshwater is acidifying The world’s freshwater appears to be acidifying. Researchers noted an […]
Genes linked to exploration in birds may help them adapt to climate change Birds whose genes favour exploration of new habitats will likely handle climate change better than those inclined to stay where they are. Researchers have identified a pair of genes, DRD4 and DEAF1, in yellow warblers that are linked to migration and exploration […]
Sponge, algae growth on rise in Caribbean reefs Sponges and algae appear to be taking over reefs from coral in the Caribbean. Fewer predators due to overfishing and coral bleaching are spurring the growth of sponges, which have developed a nutritional relationship with the algae.

Researchers scoured more than 100 historical documents and drawings to find accounts of the major event, which […]
Gravity changes could help determine quake magnitudes faster Signals from Earth’s gravitational field could help seismologists determine the magnitude of large quakes more quickly. The quicker a temblor’s actual size can be determined, the sooner emergency personnel can know how many resources may be needed to respond. Nature Large cache of fossilized pterosaur eggs found […]
Right-sided blue whales roll left when feeding Blue whales, who normally exhibit a right-side bias, change to a left-side bias when feeding on small crustaceans. Researchers attached cameras, hydrophones and sensors to blue whales and noticed that they typically roll to the left during feeding, likely to allow their dominant right eye to more effectively […]
Living stromatolites discovered in remote wetlands of Tasmania Microbial mats of living stromatolites, which first appeared on Earth at least 3.5 billion years ago but are very rare now, have been found in a remote wetland area of Tasmania. Researchers were surprised to find the stromatolites thriving in a freshwater environment since most stromatolite communities […]
