Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?
Researchers at McMaster University have developed a new drug screening technique that could lead to the rapid and accurate identification of fentanyl, as well as a vast number of other drugs of abuse, which up until now have been difficult to detect by traditional urine tests.
The method, outlined in the current edition of the journal Analytical Chemistry, addresses a serious public health emergency related to opioid addiction and unintentional overdose deaths: the lack of a reliable and inexpensive test that allows for comprehensive surveillance of synthetic drugs flooding the illegal market.
NASA-NOAA's Suomi NPP satellite has been providing forecasters with imagery of Tropical Storm Rina as it moves north through the Central Atlantic Ocean.
Study Bolsters Theory of Heat Source Under West Antarctica
A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet.
Heat from friction could power hydrothermal activity on Saturn's moon Enceladus for billions of years if the moon has a highly porous core, according to a new modeling study by European and U.S. researchers working on NASA's Cassini mission.
The study, published today in the journal Nature Astronomy, helps resolve a question scientist have grappled with for a decade: Where does the energy to power the extraordinary geologic activity on Enceladus come from?
Los negociadores sobre el clima que se reúnen en Alemania esta semana aún están a tono con el éxito del Acuerdo de París hace dos años. Pero a medida que comienzan a armar un libro de reglas para garantizar que se cumplan las promesas nacionales hechas en París, llega una dosis dura de realidad. Esas promesas, que limitan las emisiones de gases de efecto invernadero desde ahora hasta el año 2030, solo entregarán un tercio de los recortes necesarios para poner al mundo en camino de mantener el calentamiento por debajo de los 2 grados centígrados prometidos.
