Reusing low-saline oilfield water mixed with surface water to irrigate farms in the Cawelo Water District of California does not pose major health risks, as some opponents of the practice have feared, a study led by Duke University and RTI International researchers finds. This finding only applies to questions about the safety in this water district, however. Oilfield water elsewhere will have different chemistry and salinity.
Using SLAC's high-speed 'electron camera,' scientists simultaneously captured the movements of electrons and nuclei in a light-excited molecule. This marks the first time this has been done with ultrafast electron diffraction, which scatters a powerful beam of electrons off materials to pick up tiny molecular motions.
The world is currently on track to fulfil scenarios on diverting atmospheric CO2 to underground reservoirs, according to a new study by Imperial.
NUS researchers have created a device called a 'shadow-effect energy generator' that makes use of the contrast in illumination between lit and shadowed areas to generate electricity. This novel concept opens up new approaches in harnessing indoor lighting conditions to power electronics.
Researchers zeroed in on a key step of photosynthetic oxygen production. What they learned brings them one step closer to obtaining a complete picture of this natural process, which could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water.
Spring rains washes away some pollen, but not all. University of Iowa researchers have found tree pollen fragments can remain airborne for hours after a storm. The tiny pollen particles can exacerbate allergies because they can reach deep in the lungs.
The world's growing population will necessitate a 30-70% increase in food production over the next 3 decades. If we are to succeed, it will require a complete overhaul of the way we produce food. Researchers from the University of Copenhagen, among others, have now created an overview of solutions that include a number of new technologies that can collectively address this global challenge.
A faster, more efficient way of recycling plant-based 'bioplastics' has been developed by a team of scientists at the universities of Birmingham and Bath.
Tests on new designs for next-gen solar cells can now be done in minutes instead of days thanks to a new system built by scientists at Australia's Monash University, incorporating 3D-printed key components.
Discussions of drought often center on the lack of precipitation. But among climate scientists, the focus is shifting to include the growing role that warming temperatures are playing as potent drivers of greater aridity and drought intensification.
