In a first-of-its-kind analysis, Cornell researchers and partners at the Clinton Health Access Initiative found that pharmaceutical producers could reduce their environmental impact by roughly half by...
Some physical implementation schemes of quantum computing -- such as those based on superconducting qubits, quantum dots, and cold atoms -- can apply two-qubit gates only on certain pairs of qubits. O...
The purpose of this study is to provide better service to hotel customers during the COVID-19 era. Specifically, this study focuses on understanding the changes in hotel customer satisfaction during t...
Theoretical research indicates that natural selection will increase existing seasonal imbalances between the supply of nectar from flowers and the demand from bees and other insects.
Many species within Kenya's Tana River Basin will be unable to survive if global temperatures continue to rise as they are on track to do - according to new research. A new study outlines how remainin...

By uprooting carbon trapped in soil, wild pigs are releasing around 4.9 million metric tonnes of carbon dioxide annually across the globe, the equivalent of 1.1 million cars, according to new research...
New findings on the diet of Arctic foxes, determined by the condition of their teeth, show how varying climate conditions in the Arctic affect the animals that live there.In a U.S. National Scien...
New radio images from the U.S. National Science Foundation-funded Atacama Large Millimeter/submillimeter Array, ALMA, show for the first time the direct effect of volcanic activity on the at...
Thirty-one million people living in river deltas are at high risk of flooding and other impacts from tropical cyclones and climate change, according to a study by Indiana University...
In lab studies of wildfire, nitrous acid seems to be a minor actor, often underrepresented in atmospheric models. But in the real-world atmosphere during wildfires, the chemical plays a leading role.I...
Scientists have tied a shift in winter weather patterns in Europe and northern Eurasia to a reduction in aerosols -- solid particles polluting the atmosphere from activities such as burning coal.Over ...
The essential roles microbes play in deep-sea ecosystems are at risk from the potential environmental impacts of mining, a new paper in Limnology and Oceanography reports. The NSF-funded study reviews...
Climate change will ultimately affect our bridges. But to what extent?That is the question addressed by NSF-funded research conducted by David Yang and Dan Frangopol of Lehigh University in a paper re...
Over the last two decades, nanotechnology has improved many everyday products, from microelectronics to sunscreens. Nanoparticles (particles just a few hundred atoms in size) are ending up in the envi...
