Pilots and air travellers know turbulence can be powerful, but science has struggled to fully explain the phenomenon.Now, a University of Queensland study has confirmed a 70-year-old theory and is expected to help address "huge problems" in global engineering and transport.Dr Tyler Neely from the ARC Centre of Excellence for Engineered Quantum Systems (EQUS) said enormous amounts of energy were used daily to transport all sorts of fluids through pipes all over the world."Turbulence physics also causes enormous inefficiency for moving vehicles such as ships," Dr Neely said."Fluid has characteristic ways of flowing, but it goes into chaotic eddies when it gets out of equilibrium."Better understanding fluid turbulence has great potential to make many industry and transport functions cheaper and greener around the globe."
PSCs which are one of the fastest developing new solar technologies and can achieve efficiencies comparable to more commonly used commercially available silicon solar cells.For the first time, an international team of clean chemistry researchers led by Professor Joseph Shapter and Flinders University, has made very thin phosphorene nanosheets for low-temperature PSCs using the rapid shear stress of the University's revolutionary vortex fluidic device (VFD)."Silicon is currently the standard for rooftop solar, and other solar panels, but they take a lot of energy to produce them."We've found exciting new way to convert exfoliated black phosphorus into phosphorene which can help produce more efficient and also potentially cheaper solar cells," says Dr Christopher Gibson, from the College of Science and Engineering at Flinders University."Our latest experiments have improved the potential of phosphene in solar cells, showing an extra efficiency of 2%-3% in electricity production."Research into making high quality 2D phosphorene in large quantities- along with other future materials such as graphene - are paving the way to more efficient and sustainable production with the use of the SA-made VFD, near-infrared laser light pulses, and even an industrial-scale microwave oven.
A research team has developed a light beam device that could lead to faster internet, clearer images of space and more detailed medical imaging.University of Queensland researcher and optical engineer Dr Joel Carpenter worked with Nokia Bell Labs to build the device to tackle the challenge of splitting light into the shapes it is made up of, known as modes."Splitting a beam of light into colours is easy because nature gives you that one for free - think of rainbows or when light shines through glass at an angle," Dr Carpenter said."The mode sorter splits a light beam into modes, instead of pixels like a camera would, and this results in higher-quality imaging and communication.A diagram showing how the device works"Our device performs a basic operation in physics, so it seemed a little strange to us that something like this did not already exist, as this topic had been investigated around the world for about 25 years."Study co-author Nicolas Fontaine of Nokia Bell Labs said the device could bring a number of benefits.
Is it possible that there was a dinosaur on the 24 tonnes that started the high-heeled vogue already for 170 million years ago?the Fossils found near Roma in Queensland, Australia gives us an entirely new picture of how the dinosaur Rhoetosaurus feet were designed.”Look at the foot bones, it was clear that Rhoetosaurus was walking with a raised heel.How could the foot to support the huge mass of this animal, which weighed up to 40 tonnes?”, says Andréas Jannel, a doctoral student at the University of Queensland in a press release.Jannel and his colleagues used modeling techniques in 3d to develop proposals on how Rhoetosaurusen taken forward on the toes, in spite of its heavy body weight.The created copies of the remains and tested different movements to see which ones are physically possible to implement with the bones in the foot.
Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods.It is an object-oriented programming language wherein classes and procedures revolve around the same concept and classes are defined as attributes of objects.It is a dynamically typed prototype-based programming language that supports object-oriented programming.It supports exception handling mechanisms and looping constructs.It was developed at the University of Queensland, Australia.It is an interpreted computer programming language that offers object-oriented programming features.
Last month, an alarming scientific paper warned that over 40 per cent of all insect species are in decline.News of an impending “insectageddon”—a world either devoid of insects or plagued with pests—was broadcast far and wide by the media.There’s no doubt that many insects are in trouble, and that human activity has a lot to do with it.But the idea that insects as a whole will soon be gone isn’t supported by the paper, which features systemic biases and data limitations, according to two recent response letters.Both of those responses call out methodological issues with the paper, which was a meta-analysis of studies that track insect populations around the world.To see if they could tease out any global trends, the study authors from the University of Sydney and the University of Queensland searched the online database Web of Science for the keywords “insect,” “decline,” and “survey.” As critics have pointed out, these terms immediately limit the scope of analysis to studies that spot a negative trend (and to those included in the searched papers’ citations, per the meta-analysis’s methodology).
So it's not just me caught up in this craze -- search for "Ancestry DNA results" on YouTube and you'll find an entire subculture propped up by enthusiastic explorers probing their genetic histories.There's a whole genre of evening TV dedicated to analyzing the family histories of the rich and famous.That's certainly true for me, at least.The almost unfathomable complexity of all life on Earth, from bacteria to humans, relies on DNA, but the DNA code itself is made up of just four letters: A, T, C and G.These letters, known as bases, always pair together the same way -- A with T, C with G. The order in which these letters are arranged is what makes us different and gives us our unique traits.Kits provide customers with an estimation of their genetic histories, ancestries and even potential health issues they might run into.
When we are talking about sepsis - the dangerous condition when the body starts to attack its organs and tissues in attempts to fight off the bacteria or other causes - the risk of losing the patient due to sepsis increases by 4% with each hour.These sequencers stream raw data and generate results within 24 hours, which is a significant advantage, especially when doctors need to identify pathogenic species and antibiotic resistance profile.About the Project: Nanopore DNA SequencersOur team worked on the cloud-based solution for the Nanopore DNA Sequencing, and we have developed a Cloud Dataflow integrated with the following technologies:Cloud Datastore and App EngineThe pipeline itself consists of the following elements:
However issues of affordability and lack of digital literacy along with lacking locally relevant content act as an issue for m-learning in the region.Top universities and colleges in the world are also contributing to these platforms to make the learning accessible to wider audience.For example, Massachusetts Institute of Technology (MIT), Harvard University, UC Berkeley and University of Queensland Australia contribute to edX, a portal for e-learning courses offered free of cost for all users.These courses range from electronics to literature to biological sciences, and offer at free cost some of the best educational resources.are expected to move towards corporate training investment in the future just-in-time training that this platform provides coupled with the promising return on investment (ROI).The players profiled in the report include PulseLearning, CommLab India, Obsidian Learning, Designing Digitally, G-Cube, Learnnovators, LEO Learning, eWyse., GLAD Solutions, InfoPro Learning, Cinécraft Productions, Kineo, EI Design, SweetRush
A decline in insect populations happening across the planet has Earth’s ecosystems and humankind facing catastrophic consequences.The sobering message has emerged from a comprehensive review of 73 historical reports on insect population declines which found the rate of extinction is eight times faster than vertebrates such as mammals, birds and reptiles.More than a third of the world’s insects are threatened with extinction in the next few decades.They found evidence for decline in all insect groups reviewed, but said it was most pronounced for butterflies and moths, native bees, beetles and aquatic insects such as dragonflies.“From our compilation of published scientific reports, we estimate the current proportion of insect species in decline (41 percent) to be twice as high as that of vertebrates, and the pace of local species extinction (10 percent) eight times higher, confirming previous findings,” they wrote.The report highlights the ongoing loss of biodiversity as environmental degradation, pollution, over hunting, habitat loss and climate change deplete animal populations to worrying levels.
Quantum sensors being developed at the University of Queensland could revolutionise navigation and communications in unmanned and autonomous vehicles.UQ researchers are working with the Australian Defence Force (ADF), NASA, Orica Ltd and Brisbane's Skyborne Technologies to develop the next-generation sensors as part of a $6.6 million Australian initiative to develop quantum technologies for use in defence applications.UQ scientist Professor Warwick Bowen said the research could position Australia as a world-leader in ultraprecise sensors for unmanned and autonomous vehicles."Quantum sensors allow greatly improved performance and could transform navigation and positioning capabilities for unmanned vehicles."And they'll be built from both nanoengineered mechanical devices fabricated on a silicon chip, and atomic gases cooled until they behave as matter waves."The research is part of the newly created Australia-wide Quantum Technologies Research Network, set up under the Next Generation Technologies Fund.
Researchers at The University of Queensland have combined modern nanofabrication* and nanophotonics* techniques to build the ultraprecise ultrasound sensors on a silicon chip.Professor Warwick Bowen, from UQ's Precision Sensing Initiative and the Australian Centre for Engineered Quantum Systems, said the development could usher in a host of exciting new technologies."This is a major step forward, since accurate ultrasound measurement is critical for a range of applications," he said."Ultrasound is used for medical ultrasound, often to examine pregnant women, as well as for high resolution biomedical imaging to detect tumours and other anomalies."It's also commonly used for spatial applications, like in the sonar imaging of underwater objects or in the navigation of unmanned aerial vehicles.The technology is so sensitive that it can hear, for the first time, the miniscule random forces from surrounding air molecules.
Some of the creatures first discovered this year were sought by researchers — on missions to make historical finds in the depths of the ocean or deep in a cave — while others were an unexpected surprise.A group of biologists accidentally made a terrifying find in Australia over the summer — a new species of the venomous bandy-bandy snake.The team from the University of Queensland was studying sea snakes near Weipa when they randomly found the never-before-seen snake.“We later discovered that the snake had slithered over from a pile of bauxite rubble waiting to be loaded onto a ship."In the fall, scientists from Florida International University's (FIU) Tropical Conservation Institute and George Amato of the American Museum of Natural History in New York discovered a new species of the African crocodile.They named it the Central African slender-snouted crocodile.
Go below the soil, beyond the bedrock, and you’ll find a hot, sweaty underworld teeming with life that puts the surface biosphere to shame.Just how much life is down there has been an open question that the 1,200 scientists with the Deep Carbon Observatory have been trying to answer by probing the Earth’s crust.After a decade of probing, they now have an answer.An astounding 15 billion to 23 billion tonnes of carbon mass sits in the netherworld.Rick Colwell, a scientist at Oregon State who works on the Deep Carbon Observatory’s deep life census, told Gizmodo the observatory began by trying to understand how microbes living hundreds or even thousands of meters below the surface could be used to do things like, say, clean up polluted aquifers.But the more scientists poked around, the more they realised they needed to answer basic questions about life below the surface.
Researchers from the VIB-UGent Center for Plant Systems Biology, the University of Technology Sydney Climate Change Cluster and the University of Queensland have now discovered a new central enzyme in the steroid biosynthesis pathway in some modern organisms.This might not only lead to an evolutionary "re-think" but also opens new ways to control toxic algae in aquaculture.Their findings have been published in Nature Microbiology.The increasing availability of genome editing tools such as CRISPR/Cas9 is giving scientists unprecedented access to many of the inner metabolic processes that have evolved over billions of years to shape the tree of life.A new study exploring steroid biosynthesis pathways in a group of microalgae called diatoms, urges a rethink on key evolutionary aspects of eukaryotic life, the scientists say.Knowing the underlying natural metabolism of diatoms is necessary to design synthetic biology and metabolic engineering strategies for the growing biotechnology sector.
Could technology first used by NASA to grow plants on other planets also help farmers improve crop yield here on Earth?According to researchers at the U.K.’s John Innes Center and Australia’s University of Queensland the answer is “affirmative.” They are employing some of the speed breeding techniques pioneered by the U.S. aerospace program to breed more disease resistant, climate resilient, and nutritious crops.In the process, they hope to take one giant leap for humankind when it comes to creating new ways to feed the global population.They managed to breed a wheat variety specially designed for growing in space, called Apogee.It was a full dwarf variety and was selected to grow fast under a continuous 24-hour light.In long-day plants such as wheat, the extra light triggers the reproductive stage, and so plants flower earlier and produce grain faster.
An enormous ice sheet is at risk of melting even if temperatures rise by just 2 C, potentially sparking major climate chaos.Scientists say that if the East Antarctic Ice Sheet –which is 60 times the size of England – melts, sea levels could rise by four meters, putting areas of the UK at risk of disappearing entirely.Experts are now warning that more needs to be done to prevent continued global warming.Scientists have poured lots of effort into investigating the West Antarctic Ice Sheet, which mostly sits on land below sea level."However, some areas – like the Wilkes Land Subglacial Basin, directly south of Australia – are below sea level and contain enough ice to raise global sea levels by several meterss.Welsh's team examined historic ice movements to effectively predict the future.
Land-based bird populations are becoming confined to nature reserves in some parts of the world - raising the risk of global extinction - due to the loss of suitable habitat, according to a report led by UCL.Researchers analysed biodiversity in the area known as Sundaland, which covers the peninsula of Thailand, Borneo, Malaysia, Sumatra, Java and Bali, one of the world's most biologically degraded regions.The study, published today in Conservation Letters, focuses on galliformes - heavy-bodied ground-feeding birds such as pheasants, grouse and quail - as their numbers are well-recorded and they are amongst the most threatened species in some parts of the world.The island of Sumatra has suffered the highest proportion of extirpations among the areas studied, having lost 50 percent of its galliform species in unprotected land."It is also critical that protected areas are managed effectively.More land must be managed in a way that accommodates biodiversity for the long term."
Artificial intelligence is now being deployed to help curb the breeding of Aedes mosquitoes, which are responsible for the spread of such diseases as dengue, yellow fever and the Zika virus.Verily, a life sciences and healthcare company under Google's parent company Alphabet, has partnered with Singapore's National Environment Agency to bring its mosquito sex-sorting technology to the city-state.Verily announce the move, which will mark its entry into Southeast Asia, in a blog post Tuesday.The technology will be employed in the second phase of the agency's field study called "Project Wolbachia -- Singapore."This sex-sorting technology is developed under the Debug Project funded by Verily and uses a computer vision algorithm and artificial intelligence to cut down on the time spent separating male and female mosquitoes manually.As part of the project, it was used to release over a million Wolbachia-infected male Aedes mosquitoes in communities in far north Queensland in Australia in April where Verily is partners with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the University of Queensland and James Cook University.
A common antidepressant, sold under the brand name Prozac, could be helping some bacteria build resistance to antibiotics, suggests a new study from Australia.The study, published in Environment International, found that fluoxetine was capable of inducing antibiotic resistance in laboratory strains of Escherichia coli.Fluoxetine is a selective serotonin reuptake inhibitor (SSRI), a class of drug that prevents certain neurons in the brain from reabsorbing serotonin, a neurotransmitter.People with clinical depression often have less serotonin freely available, and SSRIs boost these levels, helping treat the condition to some extent.In recent years, though, there’s some research showing that SSRIs such as fluoxetine can also kill off bacteria and other microbes, sparking interest in them being used as a new type of antimicrobial.But the flip side to this realisation is the theoretical worry that fluoxetine can foster antibiotic resistance in the environment, since some of the drug ends up in our sewers after it flushes through our bodies.
