A trained detection dog can find great crested newts even through soil and at a distance, potentially aiding critical conservation efforts. The study, published in PLOS ONE, found the dog achieved an 87% success rate in detecting the species across various environmental conditions.
Researchers at Colorado State University have made a groundbreaking discovery in understanding how mountains form, revealing that deep Earth processes are the primary drivers of mountain building in subduction zones. By combining novel data sets and techniques with traditional geomorphology measurements, the team generated a long-term ...
A new study found that social support, sense of community, and depressive symptoms played a role in changes to an online gaming site's social structure over time. Members who reported more social support and a greater sense of community were more likely to form communication ties and connect with others.
Researchers argue that polders are an important part of China's water heritage, reflecting the country's long history of water management. Over 2,500 years, polders have evolved in response to changing societal needs, adapting to agricultural modernisation and urban encroachment.
A new type of satellite imagery with a spatial resolution of 15 cm has been used to detect and monitor critically endangered North Atlantic right whales. The technology allows for the identification of individual whales and their habitats, which will have significant implications for conservation efforts.
A new study reveals that Colombia's peace agreement has led to more forest loss, primarily due to increased coca farming and cattle ranching in the Andes and Amazon respectively. The research highlights the importance of considering local factors such as land use, politics, and socioeconomics in conservation efforts.
Researchers have discovered a vast icefish breeding colony in the Antarctic Weddell Sea, with an estimated 60 million active nests spanning over 240 square kilometers. The colony represents a significant biomass of more than 60,000 tons and provides insight into a globally unique ecosystem.
Researchers at the University of Otago have developed a new approach to achieve centimeter-level precise positioning on smartphones using a combination of signals from four different GNSSs. This technology has the potential to revolutionize applications requiring accurate location information, such as precise car navigation and surveying.
A study found that allowing unethical customers to open multiple accounts benefits both the retailer and ethical customers, increasing purchasing power and engagement.
New research suggests that people over-worry about waiting for a 'right time' to enjoy themselves, continually postponing fun. In contrast, studies found that leisure activities tend to be enjoyable regardless of when experienced, with some tasks even enhancing enjoyment when completed before work.
Researchers have developed a new method for surveying vegetation in dryland ecosystems using standard cameras on drones, allowing for accurate measurement of environmental change. This technique bridges the gap between satellite and on-the-ground methods, providing valuable insights into climate systems and ecosystem dynamics.
Researchers developed a bio-inspired robot that uses electrostatic forces to perch on different surfaces, reducing energy costs and increasing mission durations. The robot can resume flight after perching, making it suitable for applications such as surveying or detecting hazardous chemicals.
A team of scientists has confirmed the existence of a previously unknown wild orchid species, known as Dendrochilum hampelii, which was misidentified as 'Big Pink' in flower stalls. The discovery was made through DNA analysis and confirms that the species is separate from its cultivated relatives.
Google Street View scans help identify damage caused by the 2009 L'Aquila quake, distinguishing it from building maintenance issues. Researchers suggest using this tool for future earthquake surveys.
Scientists propose using ultraprecise atomic clocks to directly measure the Earth's true physical form, the geoid, which is currently determined indirectly through satellite tracking. This method has the potential to map the interior of the Earth to great depths, enabling more accurate exploration and discovery of subsurface structures.
Researchers at Tel Aviv University have developed an integrated method for surveying the earth for signs of valuable resources, including natural gas and oil.
