Apr. 20, 2024 Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of a landscape through space and time, may provide a key to better observing ...

Apr. 22, 2024 Researchers who study Earth's biosphere tend to operate from one of three scientific cultures, each with distinct ways of conducting science, and which have been operating mostly independently from one another. The authors identify and explain the three cultures, and suggest that reconnecting them could help accelerate biosphere ...

Apr. 22, 2024 Oases are important habitats and water sources for dryland regions, sustaining 10% of the world's population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases' fragile existence. New research shows how the world's oases have grown and shrunk over the past 25 years as water availability patterns changed and desertification ...

Apr. 19, 2024 The Dura-Europos site in modern-day Syria is famous for its exceptional state of preservation. Like Pompeii, this ancient city has yielded many great discoveries, and serves as a window into the world of the ancient Hellenistic, Parthian, and Roman periods. Yet despite the prominence of Dura-Europos in Near Eastern scholarship, there is another ...

Apr. 18, 2024 The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may have supported the activities of early life forms. Now, researchers explore how RNA elongation is regulated allosterically, shedding light on its impact ...
