Published Could we make cars out of petroleum residue?
(via sciencedaily.com) Researchers have developed a way to make lightweight fibers, for possible use in the bodies of cars, out of an ultracheap feedstock: the waste material from the refining of petroleum.
Published Turning any camera into a polarization camera
(via sciencedaily.com) Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras. The attachment uses a metasurface of subwavelength nanopillars to direct light based on its polarization and compiles an image that captures polarization at every pixel.
Published Greater greenhouse gas reductions for pickup truck electrification than for other light-duty vehicles
(via sciencedaily.com) Major automotive manufacturers are ramping up production of electric trucks as a key strategy to reduce the greenhouse gas emissions of their vehicles.
Published New, nature-inspired concepts for turning CO2 into clean fuels
(via sciencedaily.com) Researchers have developed an efficient concept to turn carbon dioxide into clean, sustainable fuels, without any unwanted by-products or waste.
Published From the streets to the stratosphere: Clean driving technology enables cleaner rocket fuel
(via sciencedaily.com) Original source A chemical used in electric vehicle batteries could also give us carbon-free fuel for space flight, according to new research.
Published Fueling a hydrogen revolution
(via sciencedaily.com) Researchers show how magnetic flux sensors can be used to monitor the operation of proton exchange membrane fuel cells that run on hydrogen. By detecting changes in current, failure states due to incorrect water levels can be identified. This work may lead to cost-effective sustainable energy generation for electric vehicles.
Published A 'fairly simple' breakthrough makes accessing stored hydrogen more efficient
(via sciencedaily.com) A new catalyst extracts hydrogen from hydrogen storage materials easily and efficiently. The process occurs at mild temperatures and under normal atmospheric conditions, without using metals or additives.
Published JET fusion facility sets a new world energy record
(via sciencedaily.com) European scientists have achieved a major success on the road to energy production through fusion plasmas: They produced stable plasmas with 59 megajoules of energy output at the world's largest fusion facility, JET, in Culham near Oxford, UK.
Published Massive methane emissions by oil and gas industry detected from space
(via sciencedaily.com) For the first time ever on a global scale, using satellite imagery, scientists have quantified volumes of massive methane emissions due to fossil-fuel extraction activities and their impact on the climate. Their findings partly explain why official inventories generally underestimate the volume of these emissions. Stopping these releases, be they accidental or deliberate, would save those countries responsible billions of dollars.
Published Fuel cells and game-changing tech to remove 99% of carbon dioxide from air
(via sciencedaily.com) Engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen.
Published New polymer fuel cells can operate at higher temperatures
(via sciencedaily.com) Original source A new high-temperature polymer fuel cell that operates at 80-160 degrees Celsius, with a higher-rated power density than state-of-the-art fuel cells, solves the longstanding problem of overheating, one of the most significant technical barriers to using medium-and heavy-duty fuel cells in transportation vehicles such as trucks and buses.
Published How fuel poverty 'gets under the skin'
(via sciencedaily.com) Original source New research shows that fuel poverty makes people's physical and mental health worse. Researchers found that not being able to keep homes warm enough affects people's levels of life satisfaction. But they also found that it impacts people's physical health by causing higher levels of inflammation, measured by fibrinogen, a blood-based biomarker.
Published Real-world study shows the potential of gait authentication to enhance smartphone security
(via sciencedaily.com) A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential crime.
Published Bulletproof fingerprint technology takes images in the round
(via sciencedaily.com) Experts have developed a unique method for retrieving high resolution images of fingermarks from curved objects like bullet casings that offers greater detail and accuracy than traditional forensic methods.
Published Securing data transfers with relativity
(via sciencedaily.com) To counter hacking, researchers have developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer.
Published Solid, liquid, or gas? Technique quickly identifies physical state of tissues and tumors
(via sciencedaily.com) Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, tumors that are more solid may be relatively stable, whereas more fluid-like growths could be more prone to mutate and metastasize.
Published Many US adults worry about facial image data in healthcare settings
(via sciencedaily.com) Uses of facial images and facial recognition technologies -- to unlock a phone or in airport security -- are becoming increasingly common in everyday life. But how do people feel about using such data in healthcare and biomedical research?
Published New DNA-based chip can be programmed to solve complex math problems
(via sciencedaily.com) A novel chip automates the reaction cascades occurring between molecules inside DNA to carry out complex mathematical calculations.
Published Face off for best ID checkers
(via sciencedaily.com) The Glasgow Face Matching Test has been updated to find super-recognizers who can help prevent errors caused by face recognition software.
Published AI system-on-chip runs on solar power
(via sciencedaily.com) Engineers have developed an integrated circuit that can carry out complicated artificial-intelligence operations like face, voice and gesture recognition and cardiac monitoring. Powered by either a tiny battery or a solar panel, it processes data at the edge and can be configured for use in just about any type of application.
