Improving reading skills through action video games
Mon, 17 Jan 2022 11:51:13 EST
What if video games, instead of being an obstacle to literacy, could actually help children improve their reading abilities? Scientists have tested an action video game for children, aimed to enhance reading skills. The results demonstrate improved reading abilities after just twelve hours of training. Notably, these gains persist over time, to the point that language school grades are seen to improve more than a year after the end of training.
Nanotherapy offers new hope for the treatment of Type 1 diabetes
Mon, 17 Jan 2022 11:51:11 EST
Individuals living with Type 1 diabetes must carefully follow prescribed insulin regimens every day, receiving injections of the hormone via syringe, insulin pump or some other device. And without viable long-term treatments, this course of treatment is a lifelong sentence. Now a team of researchers has discovered a better way.
Enhanced statistical models will aid conservation of killer whales and other species
Mon, 17 Jan 2022 09:30:07 EST
Retrieving an accurate picture of what a tagged animal does as it journeys through its environment requires statistical analysis, especially when it comes to animal movement, and the methods statisticians use are always evolving to make full use of the large and complex data sets that are available. A recent study by researchers at the Institute for the Oceans and Fisheries (IOF) and the UBC department of statistics has taken us a step closer to understanding the behaviours of northern resident killer whales by improving statistical tools useful for identifying animal behaviours that can't be observed directly.
Inciting instead of coercing, 'nudges' prove their effectiveness
Mon, 17 Jan 2022 09:30:04 EST
To get through challenges such as the pandemic or the climate change, citizens must change their habits and behaviors. But how can this be achieved without resorting to coercive measures? The answer to this question may be the 'nudges' that have been gaining popularity over the last decade. By making small changes in our environment, these interventions aim to encourage changes in our behavior, while preserving our freedom of choice. From adding informative labels to reorganizing the food offer in a cafeteria, the overall effectiveness of these interventions has now been demonstrated.
Bone growth inspired 'microrobots' that can create their own bone
Mon, 17 Jan 2022 08:58:21 EST
Inspired by the growth of bones in the skeleton, researchers have developed a combination of materials that can morph into various shapes before hardening. The material is initially soft, but later hardens through a bone development process that uses the same materials found in the skeleton.
Repeated exposure to major disasters has long-term mental health impacts
Sun, 16 Jan 2022 08:19:20 EST
Repeated exposure to major disasters does not make people mentally stronger, a recent study found: individuals who have been repeatedly exposed to major disasters show a reduction in mental health scores.
Genetic strategy reverses insecticide resistance
Fri, 14 Jan 2022 19:26:07 EST
Using CRISPR/Cas9 technology, scientists have genetically engineered a method to reverse insecticide resistance. The gene replacement method offers a new way to fight deadly malaria spread and reduce the use of pesticides that protect valuable food crops.
Powerful volcanic blast not the cause for 2018 Indonesian island collapse
Fri, 14 Jan 2022 19:26:00 EST
The dramatic collapse of Indonesia's Anak Krakatau volcano in December 2018 resulted from long-term destabilising processes, and was not triggered by any distinct changes in the magmatic system that could have been detected by current monitoring techniques, new research has found.
New study sheds light on origins of life on Earth
Fri, 14 Jan 2022 15:34:40 EST
Addressing one of the most profoundly unanswered questions in biology, a team has discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.
A catalyst for more efficient green hydrogen production
Fri, 14 Jan 2022 15:34:29 EST
Researchers have developed a new water-splitting process and material that maximize the efficiency of producing green hydrogen, making it an affordable and accessible option for industrial partners that want to convert to green hydrogen for renewable energy storage instead of conventional, carbon-emitting hydrogen production from natural gas.
Before horses, ass hybrids were bred for warfare
Fri, 14 Jan 2022 15:33:58 EST
Before the introduction of the domestic horse in Mesopotamia, valuable equids were being harnessed to ceremonial or military four wheeled wagons and used as royal gifts, but their true nature remained unknown. According to a palaeogenetic study, these prestigious animals were the result of a cross between a domestic donkey and a wild ass from Syria, now extinct. This makes them the oldest example of an animal hybrid produced by humans.
Nuclei-free cells prove utility in delivering therapeutics to diseased tissues
Fri, 14 Jan 2022 13:11:57 EST
Researchers report successfully removing the nucleus from a type of ubiquitous cell, then using the genetically engineered cell as a unique cargo-carrier to deliver therapeutics precisely to diseased tissues.
How to make sure digital technology works for the public good
Fri, 14 Jan 2022 11:57:10 EST
The Internet of Things (IoT) is completely enmeshed in our daily lives, a network of connected laptops, phones, cars, fitness trackers -- even smart toasters and refrigerators -- that are increasingly able to make decisions on their own. But how to ensure that these devices benefit us, rather than exploit us or put us at risk? New work proposes a novel framework, the 'impact universe,' that can help policymakers keep the public interest in focus amidst the rush to adopt ever-new digital technology.
Being in space destroys more red blood cells
Fri, 14 Jan 2022 11:57:08 EST
A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a new study.
Cellular receptors identified for eastern equine encephalitis
Fri, 14 Jan 2022 11:57:05 EST
A new study has identified a set of cellular receptors for at least three related alphaviruses shared across mosquitoes, humans, and animals that host the virus.
Scientists uncover 'resistance gene' in deadly E. coli
Fri, 14 Jan 2022 11:57:02 EST
Scientists have pinpointed a gene that helps deadly E. coli bacteria evade antibiotics, potentially leading to better treatments for millions of people worldwide.
Biologists pinpoint key factor in immune system response to viral infection
Fri, 14 Jan 2022 11:56:59 EST
Researchers studying how small worms defend themselves against pathogens have discovered a gene that acts as a first-line response against infection. They identified 'ZIP-1' as a centralized hub for immune response, a finding could have implications for understanding human immunity against viruses.
Arase satellite uncovers coupling between plasma waves and charged particles in Geospace
Fri, 14 Jan 2022 11:56:56 EST
Researchers show that high-frequency plasma waves in the Geospace can generate low-frequency plasma waves through wave-particle interactions by heating up low-energy ions, unveiling a new energy transfer pathway in collisionless plasma.
Creating a reference map to explore the electronic device mimicking brain activity
Fri, 14 Jan 2022 11:56:53 EST
Just like explorers need maps, scientists require guides to better understand and advance new technology. A neuromorphic device, which can mimic the neural cells in our brain, has lacked such a guideline and created headaches for scientists trying to understand their operational mechanisms. That is until now after a research group created a map that provides rational design guidelines for neuromorphic devices, paving the way for advancements in brain-inspired computers.
