Scientists propose a model to predict personal learning performance for virtual reality-based safety training      (via sciencedaily.com)     Original source 

In Korea, workers are being provided with virtual reality (VR)-based safety training content to mitigate the increase in occupational accidents. However, the current training evaluation methods suffer from a lack of immediate feedback from participants for personal learning performance evaluation. To address this, a team of researchers has now developed a new framework that uses real-time biometric data during VR training for improving personalized safety and preventing occupational hazards.

Researchers decode aqueous amino acid's potential for direct air capture of CO2      (via sciencedaily.com)     Original source 

Scientists have made a significant stride toward understanding a viable process for direct air capture, or DAC, of carbon dioxide from the atmosphere. This DAC process is in early development with the aim of achieving negative emissions, where the amount of carbon dioxide removed from the envelope of gases surrounding Earth exceeds the amount emitted.

To help autonomous vehicles make moral decisions, researchers ditch the 'trolley problem'      (via sciencedaily.com)     Original source 

Researchers have developed a new experiment to better understand what people view as moral and immoral decisions related to driving vehicles, with the goal of collecting data to train autonomous vehicles how to make 'good' decisions. The work is designed to capture a more realistic array of moral challenges in traffic than the widely discussed life-and-death scenario inspired by the so-called 'trolley problem.'

Scientists use A.I.-generated images to map visual functions in the brain      (via sciencedaily.com)     Original source 

Researchers have demonstrated the use of AI-selected natural images and AI-generated synthetic images as neuroscientific tools for probing the visual processing areas of the brain. The goal is to apply a data-driven approach to understand how vision is organized while potentially removing biases that may arise when looking at responses to a more limited set of researcher-selected images.

Phasing out fossil fuels could save millions of lives      (via sciencedaily.com)     Original source 

Scientists provide new evidence to motivate rapid fossil fuel phaseout. The science team determined exposure to ambient air pollution and its health impacts using an updated atmospheric composition model, a newly developed relative risk model and recent satellite-based fine particle data. They estimated all-cause and disease-specific mortality and attributed them to emission categories. They show that phasing out fossil fuels is a remarkably effective health-improving and life-saving intervention. About 5 million excess deaths per year globally could potentially be avoided.

Progress toward improved vaccines      (via sciencedaily.com)     Original source 

To ensure that vaccines provide strong and lasting immunization, it is often necessary to supplement the actual vaccine (antigen) with additives that stimulate the immune system: adjuvants. Today, only a few substances have been approved for use as adjuvants. A research team has now introduced a spectrum of potential adjuvants. They started with the immune stimulant ?-glactosyl ceramide (?-GalCer) and synthesized many different variants from a set of four building blocks.

Releasing brakes on biocatalysis      (via sciencedaily.com)     Original source 

Enzymes from microorganisms can produce hydrogen (H2) under certain conditions, which makes them potential biocatalysts for biobased H2 technologies. In order to make this hydrogen production efficient, researchers are trying to identify and eliminate possible limiting factors. These include formaldehyde, which occurs naturally as a metabolic product in cells and inhibits the particularly efficient [FeFe] hydrogenase.

Swapping blood for spit -- for convenient at-home health monitoring      (via sciencedaily.com)     Original source 

Blood tests are a common, yet often painful, step in health care. But what if we could skip the needles altogether? Saliva and blood contain many of the same biomarkers, and collecting spit is as simple as drooling into a container. Researchers have developed a device that detects glucose and adenosine monophosphate (AMP) biomarkers in saliva with high sensitivity, which could help make at-home health monitoring easier and without a poke.

Minimalist or maximalist? The life of a microbe a mile underground      (via sciencedaily.com)     Original source 

Researchers characterize nearly 600 microbial genomes collected from goldmine. The study illuminates 'microbial dark matter' residing below the surface. Microbes divide into two groups: minimalists that have one, specialized job or maximalists that are prepared to use any available resource. Study has implications for how underground activities, like mining and carbon storage, could affect or be affected by microbial life. The lifestyle of these 'intraterrestrial' microbes also provides hints to what organisms could be living on other planets.

Researchers have demonstrated a compact particle accelerator less than 20 meters long that produces an electron beam with an energy of 10 billion electron volts (10 GeV). There are only two other accelerators currently operating in the U.S. that can reach such high electron energies, but both are approximately 3 kilometers long. This type of accelerator is called a wakefield laser accelerator.

Innovative design achieves tenfold better resolution for functional MRI brain imaging      (via sciencedaily.com)     Original source 

Hospital MRI scanners, using 3 Tesla magnets, provide poor spatial resolution in brain imaging. More recent 7T MRIs are better but used mainly in the rare research lab. Scientists have now supercharged the standard 7T scanner to improve the resolution by nearly a factor of 10 -- a 50-times improvement over standard 3T MRIs. The NexGen 7T can track signals through the brain and perhaps tie functional changes to brain maladies.
