June 2, 2025 Some microbes living on sand grains use up all the oxygen around them. Their neighbors, left without oxygen, make the best of it: They use nitrate in the surrounding water for denitrification -- a process hardly possible when oxygen is present. This denitrification in sandy sediments in well-oxygenated waters can substantially contribute to nitrogen loss in the ...

May 28, 2025 A new species of velvet worm, Peripatopsis barnardi, represents the first ever species from the arid Karoo, which indicates that the area was likely historically more forested than at present. In the Cape Fold Mountains, we now know that every mountain peak has an endemic species. This suggests that in unsampled areas there are likely to be additional novel diversity, waiting to be ...

June 2, 2025 Global warming is continuously advancing. How quickly this will happen can now be predicted more accurately than ever before, thanks to a method developed by climate researchers. Anthropogenic global warming is set to exceed 1.5 degrees Celsius by 2028 and hence improved quantification of the Paris goals is ...

May 29, 2025 The fossils of ancient salamander-like creatures in Scotland are among the most well-preserved examples of early stem tetrapods -- some of the first animals to make the transition from water to land. Thanks to new research, scientists believe that these creatures are 14 million years older than previously thought. The new age -- dating back to 346 million years ago -- adds to the significance of ...

May 29, 2025 Replanting forests can help cool the planet even more than some scientists once believed, especially in the tropics. But even if every tree lost since the mid-19th century is replanted, the total effect won't cancel out human-generated ...

May 29, 2025 A new study reveals that the aerobic nitrogen cycle in the ocean may have occurred about 100 million years before oxygen began to significantly accumulate in the atmosphere, based on nitrogen isotope analysis from ancient South African rock cores. These findings not only refine the timeline of Earth's oxygenation but also highlight a critical evolutionary shift, where life began adapting to ...
