Scientists from TPU, Germany, and the United States have found a new way to functionalize a dielectric, otherwise known as 'white graphene', i.e. hexagonal boron nitride (hBN), without destroying it or changing its properties. Thanks to the new method, the researchers synthesized a 'polymer nano carpet' with strong covalent bond on the samples.
Archaeological excavation has, historically, operated in a very hierarchical structure, according to archaeologist Allison Mickel. The history of the enterprise is deeply entangled with Western colonial and imperial pursuits, she says. Excavations have been, and often still are, according to Mickel, led by foreigners from the West, while dependent on the labor of scores of people from the local community to perform the manual labor of the dig.
Nine years ago -April 20, 2010--crude oil began leaking from the Deepwater Horizon drilling rig into the Gulf of Mexico in what turned out to be the largest marine oil spill in history. A long-term study suggests the oil is still affecting the salt marshes of the Gulf Coast and reveals the key role that marsh grasses play in the overall recovery of these important coastal wetlands.
Nanyang Technological University, Singapore (NTU Singapore) scientists have developed a sustainable way to demonstrate a new genetic modification that can increase the yield of natural oil in seeds by up to 15 percent in laboratory conditions.
Researchers take stock of the GRACE satellite mission in Nature Climate Change
When it comes to understanding future climate, the south Asian summer monsoon offers a paradox. Most climate models predict that as human-caused global warming increases, monsoon rain and wind will become more intense--but weather data collected in the region shows that rainfall has actually declined over the past 50 years.
When thunderstorms brew over the tropics, California heat wave soon to follow
Bees are critical members of the ecosystem: 75% of leading food crops have some level of dependency on pollinators. However, native bee populations are struggling because of loss of habitat and food, often caused by urban and suburban development. The good news is that a single tree or shrub can produce thousands of flowers with high-quality pollen and nectar, providing bees with the protein and carbohydrates they need to thrive.
The study, by a team of researchers in Switzerland, provides the most up-to-date and detailed estimates of the future of all glaciers in the Alps, around 4000. It projects large changes to occur in the coming decades: from 2017 to 2050, about 50% of glacier volume will disappear, largely independently of how much we cut our greenhouse gas emissions.
Weedy rice is neither wild rice nor crop rice, but rice gone rogue that has shed some traits important to people. It also is an incredibly aggressive, potentially detrimental weed that pops up almost everywhere rice is grown, and it can reduce crop yields by more than 80 percent if it invades a field.
A new paper shows that air temperature is the "smoking gun" behind climate change in the Arctic, according to John Walsh, chief scientist for the UAF International Arctic Research Center.
A brief analysis of the existing state of American environmental policy shows that companies and activists alike have been confounded by regulations recently because they’re grown to dizzying to follow.
Boulder, Colo., USA: Steps and pools are among the most stable and functionally important features in the mountain river landscape. Their stability is important for dissipating stream energy, withstanding ordinary floods and resisting erosion, and regulating the flow and sediment dynamics feeding into lowland areas.
Nutrient pollution has been blamed for algal blooms and degradation of coral reefs along Maui's west coast
