| Researchers discover new type of ancient crater lake on Mars Posted: 30 Mar 2021 09:13 AM PDT An ancient crater lake in the southern highlands of Mars appears to have been fed by glacial runoff, bolstering the idea that the Red Planet had a cold and icy past. |
| First interstellar comet may be the most pristine ever found Posted: 30 Mar 2021 09:12 AM PDT New observations indicate that the rogue comet 2I/Borisov, which is only the second and most recently detected interstellar visitor to our Solar System, is one of the most pristine ever observed. Astronomers suspect that the comet most likely never passed close to a star, making it an undisturbed relic of the cloud of gas and dust it formed from. |
| Open-label placebo works as well as double-blind placebo in irritable bowel syndrome Posted: 30 Mar 2021 09:12 AM PDT In a randomized clinical trial, researchers found participants with moderate to severe irritable bowel syndrome (IBS) who were knowingly treated with a pharmacologically inactive pill -- referred to as an honest or open-label placebo -- reported clinically meaningful improvements in their IBS symptoms. |
| In the deep sea, the last ice age is not yet over Posted: 30 Mar 2021 09:12 AM PDT While investigating gas hydrate deposits in the western Black Sea, a team of scientists made surprising discoveries. Contrary to previous findings and theories, the scientists found free methane gas in layers where it should actually not appear. The authors conclude that the gas hydrate system in the deep-sea fan of the Danube continues to adapt due to climate changes since the last glacial maximum. |
| Posted: 24 Mar 2021 06:47 AM PDT The largest flightless bird ever to live weighed in up to 600kg and had a whopping head about half a meter long - but its brain was squeezed for space. Dromornis stirtoni, the largest of the 'mihirungs' (an Aboriginal word for 'giant bird'), stood up to 3m and had a cranium wider and higher than it was long due to a powerful big beak, leading Australian palaeontologists to look inside its brain space to see how it worked. |
