Researchers have decoded the genetic map for how maize from tropical environments can be adapted to the temperate US summer growing season. They believe that if they can expand the genetic base by using exotic varieties, they might be able to counter stresses such as emerging diseases and drought associated with growing corn in a changing climate.
There are two tropical cyclones affecting American Samoa in the South Pacific Ocean on Feb. 21. Tropical Storm Vicky has triggered warnings, while Tropical Cyclone 18P continues to develop. The Global Precipitation Measurement mission or GPM satellite provided a look at the rainfall rates occurring in both storms.
The low-pressure area that has been lingering west-northwest of American Samoa for several days has organized into a tropical depression. NASA's Terra satellite passed over the Southern Pacific Ocean and provided forecasters with a visible image of Tropical Depression 18P.
Advanced leaf-out enhances annual surface warming in the Northern Hemisphere
If China is to meet and exceed its Paris Climate Agreement goal by 2030, it's going to need to find a way to increase its wind capacity. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Huazhong University of Science and Technology in China, found that offshore wind could be a big part of the solution.
At least 26 per cent of our oceans need urgent conservation attention to preserve Earth's marine biodiversity, a University of Queensland-led international study has found. Dr Kendall Jones said the international community needed to rapidly increase marine conservation efforts to maintain the health of the world's oceans.
In a study published in Scientific Reports, a team of international researchers led by University of Hawai'i (UH) at Mānoa postdoctoral fellow Jamie Caldwell used a statistical technique typically employed in human epidemiology to determine the ecological risk factors affecting the prevalence of two coral diseases--growth anomalies, abnormalities like coral tumors, and white syndromes, infectious diseases similar to flesh eating bacteria.
Cornell University researchers have found a new species of soil bacteria that is particularly adept at breaking down organic matter, including the cancer-causing chemicals that are released when coal, gas, oil and refuse are burned.
In several new studies, University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researcher Katharine Mach and colleagues explore the importance of learning and knowledge in environmental decision-making and the different ways in which scientific knowledge can become more relevant and useful for societies.
In a new paper, climate scientists at the University of Massachusetts Amherst and Woods Hole Oceanographic Institution propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8,000 to 13,000 years ago. Details of how they tested this idea for the first time are online now in Geology.
