Published Simple new process stores CO2 in concrete without compromising strength
(via sciencedaily.com) Original source By using carbonated -- rather than still -- water during the concrete manufacturing process, a team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction material.
Published Solar technology: Innovative light-harvesting system works very efficiently
(via sciencedaily.com) Original source Researchers are reporting progress on the road to more efficient utilization of solar energy: They have developed an innovative light-harvesting system.
Published Microrobot-packed pill shows promise for treating inflammatory bowel disease in mice
(via sciencedaily.com) Original source Engineers have developed a pill that releases microscopic robots, or microrobots, into the colon to treat inflammatory bowel disease (IBD). The experimental treatment, given orally, has shown success in mice. It significantly reduced IBD symptoms and promoted the healing of damaged colon tissue without causing toxic side effects.
Published Future risk of coral bleaching set to intensify globally
(via sciencedaily.com) Original source Researchers have projected future marine heatwaves will cause coral reefs to be at severe risk of bleaching for longer periods than previously seen.
Published Ocean's loss of oxygen caused massive Jurassic extinction: Could it happen again?
(via sciencedaily.com) Original source Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans.
Published An optical lens that senses gas
(via sciencedaily.com) Original source A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled by the hybrid glass material from which it is made. The molecular structure of the lens consists of a three-dimensional lattice with cavities that can accommodate gas molecules, thereby affecting the optical properties of the material.
Published Towards non-toxic antifouling agents: A novel method for total synthesis of scabrolide F
(via sciencedaily.com) Original source Norcembranolide diterpenes, isolated from the soft corals of the genus Sinularia, are important compounds for the development of new drugs, owing to their diverse biological activities. However, total synthesis methods for these compounds are scarce. Now, a team of researchers has achieved the total synthesis of scabrolide F, a norcembranolide diterpene. They also revealed its non-toxic antifouling properties. This novel method can lead to the development of new drugs and antifouling agents.
Published Plankton researchers urge their colleagues to mix it up
(via sciencedaily.com) Original source A new article encourages researchers to focus their attention on mixoplankton, providing a set of methodologies to help expand our understanding of this critically important component of the marine ecosystem.
Published Novel application of optical tweezers: Colorfully showing molecular energy transfer
(via sciencedaily.com) Original source Using a novel non-contact approach, a research team has successfully controlled the speed and efficiency of Forster resonance energy transfer between fluorescent molecules by varying the intensity of a laser beam.
Published New study confirms forever chemicals are absorbed through human skin
(via sciencedaily.com) Original source A study of 17 commonly used synthetic 'forever chemicals' has shown that these toxic substances can readily be absorbed through human skin.
Published Novel catalysts for improved methanol production using carbon dioxide dehydrogenation
(via sciencedaily.com) Original source Encapsulating copper nanoparticles within hydrophobic porous silicate crystals has been shown to significantly enhance the catalytic activity of copper-zinc oxide catalysts used in methanol synthesis via CO2 hydrogenation. The innovative encapsulation structure effectively inhibits the thermal aggregation of copper particles, leading to enhanced hydrogenation activity and increased methanol production. This breakthrough paves the way for more efficient methanol synthesis from CO2.
Published Promise green hydrogen may not always be fulfilled
(via sciencedaily.com) Original source Green hydrogen often, but certainly not always, leads to CO2 gains.
Published Membrane protein analogues could accelerate drug discovery
(via sciencedaily.com) Original source Researchers have created a deep learning pipeline for designing soluble analogues of key protein structures used in pharmaceutical development, sidestepping the prohibitive cost of extracting these proteins from cell membranes.
Published Scientists devise algorithm to engineer improved enzymes
(via sciencedaily.com) Original source Scientists have prototyped a new method for 'rationally engineering' enzymes to deliver improved performance. They have devised an algorithm, which takes into account an enzyme's evolutionary history, to flag where mutations could be introduced with a high likelihood of delivering functional improvements. Their work could have significant, wide-ranging impacts across a suite of industries, from food production to human health.
Published Much of the Nord Stream gas remained in the sea
(via sciencedaily.com) Original source Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.
Published Mirror-image chemicals may revolutionize drug delivery
(via sciencedaily.com) Original source More than 130 years after cyclodextrins were first discovered and reported, a team of scientists has created chemical mirror images of these complex carbohydrates in the laboratory. This discovery may revolutionize how medications are delivered to patients.
Published Restored rat-free islands could support hundreds of thousands more breeding seabirds
(via sciencedaily.com) Original source Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.
Published New study shows mechanisms of Hagfish burrowing into deep sea sediment
(via sciencedaily.com) Original source Scientists have developed a novel way to observe the elusive burrowing behavior of hagfish. Scientists created a specialized tank of transparent gelatin in order to visualize how the hagfish behave and locomote within sediments.
Published New material puts eco-friendly methanol conversion within reach
(via sciencedaily.com) Original source Researchers have developed innovative, eco-friendly quantum materials that can drive the transformation of methanol into ethylene glycol. This discovery opens up new possibilities for using eco-friendly materials in photocatalysis, paving the way for sustainable chemical production.
Published Custom-made molecules designed to be invisible while absorbing near-infrared light
(via sciencedaily.com) Original source Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This compound demonstrates the first systematic approach to producing such materials and have applications in advanced electronics. This compound also shows semiconducting properties.
