Published AI-equipped eyeglasses read silent speech
(via sciencedaily.com) Original source Researchers have developed a silent-speech recognition interface that uses acoustic-sensing and artificial intelligence to continuously recognize up to 31 unvocalized commands, based on lip and mouth movements.
Published Technology advance paves way to more realistic 3D holograms for virtual reality and more
(via sciencedaily.com) Original source Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.
Published How to overcome noise in quantum computations
(via sciencedaily.com) Original source Scientists have made significant progress in quantum computing by deriving a formula that predicts the effects of environmental noise. This is crucial for designing and building quantum computers capable of working in our imperfect world.
Published New pesticide exposure test developed to protect inexperienced cannabis farmers
(via sciencedaily.com) Original source Chemists created a more reliable, robust and efficient way to monitor pesticide exposure and help protect the health and safety of agricultural workers, especially for emerging sectors like the cannabis industry.
Published Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease
(via sciencedaily.com) Original source Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.
Published Air pollution may increase risk for dementia
(via sciencedaily.com) Original source Exposure to fine particulate air pollutants (PM2.5) may increase the risk of developing dementia, according to a new meta-analysis.
Published Gone for good? California's beetle-killed, carbon-storing pine forests may not come back
(via sciencedaily.com) Original source Ponderosa pine forests in the Sierra Nevada that were wiped out by western pine beetles during the 2012-2015 megadrought won't recover to pre-drought densities, reducing an important storehouse for atmospheric carbon.
Published Surprising science behind bumblebee superfood
(via sciencedaily.com) Original source It's the spines. New research shows that the spiny pollen from plants in the sunflower family (Asteraceae) both reduces infection of a common bee parasite by 81 -- 94% and markedly increases the production of queen bumble bees. The research provides much-needed food for thought in one of the most vexing problems facing biologists and ecologists: how to reverse the great die-off of the world's pollinators.
Published Opening a new frontier: PdMo intermetallic catalyst for promoting CO2 utilization
(via sciencedaily.com) Original source A recently discovered catalyst, can convert carbon dioxide (CO2) into useful methanol at room temperature and low-pressure conditions. This novel compound, which is thermally and chemically stable in air, represents a new milestone in CO2 conversion via hydrogenation and could be key to slow down climate change.
Published Robots predict human intention for faster builds
(via sciencedaily.com) Original source Humans have a way of understandings others' goals, desires and beliefs, a crucial skill that allows us to anticipate people's actions. Taking bread out of the toaster? You'll need a plate. Sweeping up leaves? I'll grab the green trash can. This skill, often referred to as 'theory of mind,' comes easily to us as humans, but is still challenging for robots. But, if robots are to become truly collaborative helpers in manufacturing and in everyday life, they need to learn the same abilities. Computer science researchers aim to teach robots how to predict human preferences in assembly tasks, so they can one day help out on everything from building a satellite to setting a table.
Published Students use machine learning in lesson designed to reveal issues, promise of A.I.
(via sciencedaily.com) Original source In a new study, researchers had 28 high school students create their own machine-learning artificial intelligence (AI) models for analyzing data. The goals of the project were to help students explore the challenges, limitations and promise of AI, and to ensure a future workforce is prepared to make use of AI tools.
Published Was plate tectonics occurring when life first formed on Earth?
(via sciencedaily.com) Original source Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet. This finding could prove beneficial in the search for life on other planets.
Published New insights into engineering climate-smart crops for the future
(via sciencedaily.com) Original source New research in the field of plant sciences has made significant advances towards understanding the underlying reasons behind why certain crops are better at generating more yield than others.
Published Scientists use computational modeling to design 'ultrastable' materials
(via sciencedaily.com) Original source Researchers developed a computational approach to predict which metal-organic framework (MOF) structures will be the most stable, and therefore the best candidates for applications such as capturing greenhouse gases.
Published Absolute zero in the quantum computer
(via sciencedaily.com) Original source Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum physics have now found out that there is a third option: Infinite complexity. It turns out that reaching absolute zero is in a way equivalent to perfectly erasing information in a quantum computer, for which an infinetly complex quantum computer would be required.
Published Discovery of crucial clue to accelerate development of carbon-neutral porous materials
(via sciencedaily.com) Original source A recent study has provided a library of those various molecular clusters for future metal building blocks of MOFs, and suggested practical synthetic strategies.
Published Origami-inspired robots can sense, analyze and act in challenging environments
(via sciencedaily.com) A multidisciplinary team has created a new fabrication technique for fully foldable robots that can perform a variety of complex tasks without relying on semiconductors.
Published Strong ultralight material could aid energy storage, carbon capture
(via sciencedaily.com) Original source Materials scientists showed that fine-tuning interlayer interactions in a class of 2D polymers can determine the materials' loss or retention of desirable mechanical properties in multilayer or bulk form.
Published Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk
(via sciencedaily.com) Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.
Published Smart watches could predict higher risk of heart failure
(via sciencedaily.com) Original source A study looked at data from 83,000 people who had undergone a 15-second electrocardiogram (ECG) comparable to the kind carried out using smart watches and phone devices. The researchers identified ECG recordings containing extra heart beats which are usually benign but, if they occur frequently, are linked to conditions such as heart failure and arrhythmia (irregular heartbeats). They found that people with an extra beat in this short recording (one in 25 of the total) had a twofold risk of developing heart failure or an irregular heart rhythm (atrial fibrillation) over the next 10 years.
