UAEU College of Science first in region to launch groundwater reservoir radioactive isotopes distribution map

The College of Science at the United Arab Emirates University, UAEU, has recently successfully launched the first phase of groundwater radioactivity mapping in the country, in the presence of the Dean of the College of Science, Professor Ahmed Murad, the scientific research team, faculty members, and the college community. The first phase covered the eastern and northern areas of the country. The mapping of radioactivity in groundwater is a vital and innovative research project to monitor water resources and baseline radioactivity in the UAE. Read more.

Biosphere 2 isotope lab measures age of water

Did you ever wonder how old the water is that you see flowing at Sabino Dam in Arizona? Probably not, if you’re not a hydrologist. But this is an important question in relation to the water resources available in our water-stressed environment. Read more.

Earth’s water must have arrived here earlier than we thought

The arrival of water on our planet is shrouded in mystery. Our leading theory says icy meteorites brought it here after most of the planet and its core had formed, about 4.5 billion years ago. But now an analysis of isotopes from meteorites seems to imply that the wet stuff got here much sooner. Read more.

New evidence reveals climate change killed the big animals of Australia’s ice age

During the Ice Age, things were a bit different than they are today in the land of Sahul. If the name Sahul doesn’t ring a bell, it is probably because it isn’t a place anymore. It is the landmass that includes Australia, Tasmania, and New Guinea—all once connected. At times of lower sea level when water is locked up in ice, the continental shelf is exposed and merges all of these seemingly separate swathes of land.

During this last glacial maximum, the continent was teeming with giants like 500-pound kangaroos, massive fuzzy wombat-relatives, and 20-foot-long crocodiles. But around 30,000 years ago, these enormous land dwellers had almost disappeared. A whopping 88 species of mammals went extinct in Sahul between 500,000 and 30,000 years ago, but why? Read more.
