In the driest state in the driest continent in the world, South Australian farmers are acutely aware of the impact of water shortages and drought. So, when it comes to irrigation, knowing which method works best is vital for sustainable crop development.
Now, new research from the University of South Australia shows that water quality and deficit irrigation schemes each have significant effects on crop development, yield and water productivity - with recycled wastewater achieving the best overall results.
The research, published today in the journal PLOS One, focused on Chironex fleckeri - a large jellyfish capable of killing a human in under three minutes and considered the most venomous animal in the world.
"Chironex fleckeri is found in waters off northern Australia from October to May, when its liking for shallow, calm, coastal waters can put it on a collision course with swimmers," said PhD candidate and project lead Olivia Rowley.
"Drone surveillance could help make our beaches safer, and reduce our reliance on time-consuming drag netting by life savers."
EVANSTON, Ill. --- We've long been warned of the risks of dyeing hair at home and in salons. Products used can cause allergies and skin irritation -- an estimated 1% of people have an allergy to dye. Furthermore, repeated use of some dyes has been linked to cancer.
But there soon may be a solution for the growing list of salons and hair color enthusiasts searching for natural alternatives to dyes and cosmetics.
Australian bees are known for pollinating plants on beautiful sunny days, but a new study has identified two species that have adapted their vision for night-time conditions for the first time.
The study by a team of ecology researchers has observed night time foraging behaviour by a nomiine (Reepenia bituberculata) and masked (Meroglossa gemmata) bee species, with both developing enlarged compound and simple eyes which allow more light to be gathered when compared to their daytime kin.
Specially-adapted drones developed by a UCL-led international team have been gathering data from never-before-explored volcanoes that will enable local communities to better forecast future eruptions.
The cutting-edge research at Manam volcano in Papua New Guinea is improving scientists' understanding of how volcanoes contribute to the global carbon cycle, key to sustaining life on Earth.

Tiny, seemingly harmless ocean plants survived the darkness of the asteroid strike that killed the dinosaurs by learning a ghoulish behavior -- eating other living creatures.
Vast amounts of debris, soot, and aerosols shot into the atmosphere when an asteroid slammed into Earth 66 million years ago, plunging the planet into darkness, cooling the climate, and acidifying the oceans. Along with the dinosaurs on the land and giant reptiles in the ocean, the dominant species of marine algae were instantly wiped out -- except for one rare type.
San Juan Capistrano, Calif. -- A new case report published in the Journal of Vascular Surgery provides one of the first known opportunities to directly visualize the permanent and fused connection (anastomosis) that is created with the minimally invasive Ellipsys® Vascular Access System.
Tsukuba, Japan - A research team from the University of Tsukuba has conducted detailed structural analyses of a fault zone located in central Japan, with the aim to help identify the specific conditions that lead to earthquake faulting, a hazard that can cause enormous social damage. Subduction is a geological process that takes place in areas where two tectonic plates meet, such as the Japan Trench, in which one plate moves under another and is forced to sink.
The Laboratory of Enzyme Biosynthesis and Bioengineering of Kazan Federal University is engaged in several projects in fundamental and applied fields of biology and medicine. For several years, the main focus of research has been the production and characterization of enzymes. Enzymes such as subtilisin-like proteinase, glutamyl endopeptidase, and metalloproteinase have been described in detail in the dissertations of Ye. Mikhailova, T. Shamsutdinov, and N. Rudakova, respectively.
Earth and all the living organisms on it are constantly changing. But is there any way we can detect if these changes are occurring at an abnormal rate? What are the consequences of these changes for the organisms affected? An international team of researchers including scientists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a method of detecting such developments and tracking how new ecosystems are formed. They have published their findings in the specialist journal Science.
Polypropylene (PP) is one of the most widely used plastics in the world. By controlling the spatial orientation of the propylene building blocks and additional polar components, it should be possible to create a new generation of attractive, engineered, specialty plastics, with improved wettability or enhanced degradability, based on PP. In the journal Angewandte Chemie, Japanese scientists have introduced the basis for a new class of palladium catalysts for such polymerizations.
CHAPEL HILL, N.C. - Oct. 30, 2020 - In 2007, UNC researchers published unexpected and surprising results from a study based on magnetic resonance imaging (MRI) of newborn brains. Twenty-six percent of the newborns in the study were found to have asymptomatic subdural hemorrhages, or bleeding in and around the brain.
It was an unexpected finding because subdural hemorrhage had been considered unusual in full-term newborns. But the 2007 findings suggested that small, asymptomatic brain bleeds might be a fairly common consequence of a normal vaginal delivery.
When atoms get extremely close, they develop intriguing interactions that could be harnessed to create new generations of computing and other technologies. These interactions in the realm of quantum physics have proven difficult to study experimentally due the basic limitations of optical microscopes.
Now a team of Princeton researchers, led by Jeff Thompson, an assistant professor of electrical engineering, has developed a new way to control and measure atoms that are so close together no optical lens can distinguish them.
Kinship caregiving--placing a child in a relative's home if the child cannot safely stay in the family home--is becoming more common and is a preferred option for children, says UBC Okanagan Assistant Professor Sarah Dow-Fleisner.
The study, originally conducted at the Children and Family Research Center as part of the University of Illinois School of Social Work, was reanalyzed by UBCO student Kathrine Stene as part of an honours thesis in psychology and completed by researchers at UBCO's Centre for the Study of Services to Children and Families.
