Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving parts.
Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.
Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Isotopic data, along with DNA from other mammoths at the site and archaeological evidence, indicates that early Alaskans likely structured their settlements to overlap with areas where mammoths congregated. Those findings, highlighted in the new issue of the journal Science Advances, provide evidence that mammoths and early hunter-gatherers shared habitat in the region. The long-term predictable presence of woolly mammoths would have attracted humans to the area.
Having more women in agriculture is associated with greater community well-being, according to researchers. Their work suggests that women farmers approach their operations in ways that positively impact their communities.
The Kalpana 1 and INSATs 3A, 3D, and 3DR satellites have bolstered India’s weather monitoring and warning services
Science communication in India has new opportunities today – even as it exposes old and new lacunae
Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface previously thought to be 'featureless' holds an unmistakable signature that could lead to the first definitive observation.
Researchers report the development of a methodology to detect small amounts of potential tumor therapeutic targets, specificacally enzymes called kinases, that are present in biopsy samples. Therapies that directly inhibit cancer-promoting activities of some of these kinases have proven to be effective for patients in which individual driving kinases can be diagnosed.
Sustainable water management is an increasing concern in arid regions around the world, and scientists and regulators are turning to remote sensing tools like OpenET to help track and manage water resources. OpenET uses publicly available data produced by NASA and USGS Landsat and other satellite systems to calculate evapotranspiration (ET), or the amount of water lost to the atmosphere through soil evaporation and plant transpiration, at the level of individual fields. This tool has the potential to revolutionize water management, allowing for field-scale operational monitoring of water use, and a new study provides a thorough analysis of the accuracy of OpenET data for various crops and natural land cover types.
Scientists recently revealed the latest National Seismic Hazard Model, showing that nearly 75% of the United States could experience a damaging earthquake, emphasizing seismic hazards span a significant part of the country.
