Edge processing research takes discovery closer to use in artificial intelligence networks
- ScienceDaily
- 22/1/18 16:41
Researchers have successfully demonstrated proof-of-concept of using their multimodal transistor (MMT) in artificial neural networks, which mimic the human brain. This is an important step towards using thin-film transistors as artificial intelligence hardware and moves edge computing forward, with the prospect of reducing power needs and improving efficiency, rather than relying solely on...
Integrated modeling of climate impacts on electricity demand and cost

An innovative method of controlling a range of damaging crop diseases using native, beneficial soil bacteria has emerged from a research-industry collaboration.
'Rivers' in the sky likely to drench East Asia under climate change
- ScienceDaily
- 22/1/18 16:41
Extreme rainfall events associated with atmospheric rivers, narrow bands transporting large amounts of moisture in the atmosphere, are becoming more frequent and severe in mountainous parts of East Asia as the climate changes. According to global and regional climate models comparing historical trends with a future scenario of 4 degrees of warming of global-mean surface air, these events are...
Researchers explore ways to make hatchery steelhead more like wild fish
- ScienceDaily
- 22/1/18 16:41
Hatchery-raised steelhead trout have offspring that are good at gaining size under hatchery conditions but don't survive as well in streams as steelhead whose parents are wild fish, new research shows.
New MRI technique could improve diagnosis and treatment of multiple sclerosis
- ScienceDaily
- 22/1/18 16:41
It is important that multiple sclerosis (MS) is diagnosed and treated as early as possible in order to delay progression of the disease. The technique of magnetic resonance imaging (MRI) plays a key role in this process. A new MRI technique could pave the way to quicker assessment of disease activity in MS.
Epidemiologists develop advanced state-of-the-art tool for measuring the pace of aging
- ScienceDaily
- 22/1/18 16:37
Researchers developed a new blood test to measure the pace of biological aging. Based on an analysis of chemical tags on the DNA contained in white blood cells, called DNA methylation marks, the new test is named DunedinPACE (Pace of Aging Computed from the Epigenome). DunedinPACE is a new addition to a fast-growing list of DNA methylation tests designed to measure aging and contributes...
Nearly half of countries' shared fish stocks are on the move due to climate change, prompting dispute concerns
- ScienceDaily
- 22/1/18 15:41
Climate change will force 45 per cent of the fish stocks that cross through two or more exclusive economic zones to shift significantly from their historical habitats and migration paths by 2100, a challenge that may lead to international conflict, according to a new study.
Celebrated malting barley came from a single plant
- ScienceDaily
- 22/1/18 14:54
The 200-year-old malting barley variety 'Chevalier' was for a long time world-leading in beer brewing and is thought to have originated from a single plant. In a new study, researchers have investigated this claim. They have analyzed seed samples that are older than 150 years using molecular genetic methods. The results give a revealing insight into the plant breeding of times gone by.
Respiratory viruses that hijack immune mechanisms may have Achilles' heel
- ScienceDaily
- 22/1/18 14:54
One viral protein could provide information to deter pneumonia causing the body's exaggerated inflammatory response to respiratory viruses, including the virus that causes COVID-19. That viral protein is NS2 of Respiratory Syncytial Virus (RSV), and a study has found that if the virus lacks this protein, the human body's immune response can destroy the virus before exaggerated inflammation begins....
Intracellular supramolecular self-assembly regulates cellular function
Supramolecular self-assembly based on noncovalent interactions is considered as a key strategy for introducing intracellular synthetic biocompatible macromolecules. The synthetic macromolecules resemble the nature, behavior, and function of biomacromolecules in living systems.
Hetero-lattice intergrown MOF membranes: A potential solution to polyol upgrading in industry
Metal-organic frameworks (MOFs) bring tremendous opportunities for separation of liquid chemicals using membranes.
Novel design method proposed for reflective optical system with low tilt-error sensitivity
Characterized by large aperture and long focal length, the reflective optical system has the advantages of small number of optical elements and simple optical structure. But the intrinsic aberration and the misalignment derived aberration increase exponentially with the increase of focal length and aperture, resulting in a significant degradation of the optical system imaging quality caused by...
Understanding rare rain events in the driest desert on Earth
In the enduring dryness of the Atacama Desert in northern Chile where the average rainfall is as low as 5 millimeters per year, rare rain events can come swiftly and intensely. They shape the landscape and provide precious moisture to plants and other species that otherwise adapted to extended dry spells or harvesting coastal fog. Intense rain events like those seen in the Atacama are known to be...
Climate change threatens future Winter Olympics
Climate change will limit where the Winter Olympics can be held as winter changes across the Northern Hemisphere, according to a study by an international team of researchers led by the University of Waterloo.
Controlling how 'odd couple' surfaces and liquids interact
The wettability of a surface—whether drops of water or another liquid bead up or spread out when they come into contact with it—is a crucial factor in a wide variety of commercial and industrial applications, such as how efficiently boilers and condensers work in power plants or how heat pipes funnel heat away in industrial processes. This characteristic has long been seen as a fixed property...
Conversations about consent need to start early, and parents need to get comfortable with it
Psychiatrist Dr. Gaiathry Jeyarajan envisions a future where parents are comfortable having conversations with their kids early on about consent and boundaries. Avoiding these discussions only perpetuates the culture of silence that allows interpersonal trauma to thrive, says Jeyarajan.
Why are zebra mussels so sticky? Study may lead to new industrial coatings, medical adhesives
A water tank full of coin-sized invertebrates may not be the first thing you'd expect to see in a materials science and engineering research lab.

Every year thousands of students enroll in Ph.D. degrees at universities in New Zealand. The government funds their degrees because the advanced knowledge and innovations they develop benefit our economy and society.
Mythologised, memorialised then forgotten: A history of Australia's bushfire reporting
Australia's Black Summer bushfires of 2019 and 2020 wreaked destruction across South-Eastern Australia. Images of flames crowned trees, engulfed fire trucks and people crowded on beaches and packed in boats were broadcast into our homes.

Look up and watch asteroid 1994 PC1 fly past Earth this week
In a slow moving universe, asteroids give us a rare chance to see things moving in real time. We have such a chance coming right up on the evening of Tuesday, January 18, when 1.1-kilometer asteroid (7482) 1994 PC1 passes 1.23 million miles (1.98 million kilometers) from the Earth. This is about five times the distance from the Earth to the moon, and just a shade over the distance to the...
Nanobubbles provide pathway to build better medical devices
Researchers from the University of Sydney Nano Institute and School of Chemistry have revealed that tiny gas bubbles—nanobubbles just 100 billionths of a meter high—form on surfaces in unexpected situations, providing a new way to reduce drag in small-scale devices.
