Published Not the usual suspects: New interactive lineup boosts eyewitness accuracy
(via sciencedaily.com) Original source Allowing eyewitnesses to dynamically explore digital faces using a new interactive procedure can significantly improve identification accuracy compared to the video lineup and photo array procedures used by police worldwide, a new study reveals.
Published Small but mighty new gene editor
(via sciencedaily.com) Original source A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.
Published Ball milling provides high pressure benefits to battery materials
(via sciencedaily.com) Original source Cheaper, more efficient lithium-ion batteries could be produced by harnessing previously overlooked high pressures generated during the manufacturing process.
Published Ultrasound may rid groundwater of toxic 'forever chemicals'
(via sciencedaily.com) Original source New research suggests that ultrasound may have potential in treating a group of harmful chemicals known as PFAS to eliminate them from contaminated groundwater.
Published Researchers dynamically tune friction in graphene
(via sciencedaily.com) Original source The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers.
Published Toxic formaldehyde's dual nature to be probed with new chemical tool
(via sciencedaily.com) Original source Newly developed ompounds aim to reveal the dual nature of formaldehyde, a chemical that is known to cause cancer but is also believed to play important roles in our biology.
Published Scientists unveil fire-safe fuel
(via sciencedaily.com) Original source Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a 'safe' liquid fuel.
Published A new twist on rechargeable battery performance
(via sciencedaily.com) Original source Rechargeable battery performance could be improved by a new understanding of how they work at the molecular level. Researchers upend what's known about how rechargeable batteries function.
Published Accelerating sustainable semiconductors with 'multielement ink'
(via sciencedaily.com) Original source Scientists have demonstrated 'multielement ink' -- the first 'high-entropy' semiconductor that can be processed at low-temperature or room temperature. The new material could enable cost-effective and energy-efficient semiconductor manufacturing.
Published Tiny CRISPR tool could help shred viruses
(via sciencedaily.com) Original source Scientists mapped out the three-dimensional structure of one of the smallest known CRISPR-Cas13 systems then used that knowledge to modify its structure and improve its accuracy.
Published Down goes antimatter! Gravity's effect on matter's elusive twin is revealed
(via sciencedaily.com) For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.
Published Separating molecules requires lots of energy. This new, heat-resistant membrane could change that
(via sciencedaily.com) Original source A research team has created a new, heat-resistant membrane that can withstand harsh environments -- high temperatures, high pressure and complex chemical solvents -- associated with industrial separation processes. It could eventually be used as a less energy intensive alternative to distillation and other industrial processes that separate molecules that ultimately serve as ingredients in medicine, chemicals and other products.
Published How organic solar cells could become significantly more efficient
(via sciencedaily.com) Original source The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.
Published New insights into the atmosphere and star of an exoplanet
(via sciencedaily.com) A new study of the intriguing TRAPPIST-1 exoplanetary system has demonstrated the complex interaction between the activity of the system's star and its planetary features.
Published Hidden supermassive black holes reveal their secrets through radio signals
(via sciencedaily.com) Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies.
Published Copper-based catalysts efficiently turn carbon dioxide into methane
(via sciencedaily.com) Copper-based catalysts developed by materials scientists help speed up the rate of carbon dioxide-to-methane conversion.
Published Drug discovery on an unprecedented scale
(via sciencedaily.com) Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
Published There is much to improve in identifying all the chemicals around us
(via sciencedaily.com) What chemicals are we exposed to on a daily basis? That is the central question of 'non-targeted analysis' or NTA, an emerging field of analytical science that aims to identify all chemicals around us. A daunting task, because how can you be sure to detect everything if you don't know exactly what you're looking for?
Published Nanoparticles made from plant viruses could be farmers' new ally in pest control
(via sciencedaily.com) Engineers have devised a new solution to control a major agricultural menace, root-damaging nematodes. Using plant viruses, the researchers created nanoparticles that can deliver pesticide molecules to previously inaccessible depths in the soil. This 'precision farming' approach could potentially minimize environmental toxicity and cut costs for farmers.
Published Scaling up the power of nanotechnology
(via sciencedaily.com) Researchers created a proof of concept of a nanocapsule -- a microscopic container -- capable of delivering a specific 'payload' to a targeted location. While beyond the scope of this study, the discovery could one day impact how drugs, nutrients and other types of chemical compounds are delivered within humans or plants.
