| Shape-morphing microrobots deliver drugs to cancer cells Posted: 17 Nov 2021 07:38 AM PST Chemotherapy successfully treats many forms of cancer, but the side effects can wreak havoc on the rest of the body. Delivering drugs directly to cancer cells could help reduce these unpleasant symptoms. Now, in a proof-of-concept study, researchers have made fish-shaped microrobots that are guided with magnets to cancer cells, where a pH change triggers them to open their mouths and release their chemotherapy cargo. |
| Virtual fluid for the description of interfacial effects in metallic materials Posted: 17 Nov 2021 07:01 AM PST A research group presents a new simulation method for describing the attachment of a liquid to a surface. |
| New holographic camera sees the unseen with high precision Posted: 17 Nov 2021 07:01 AM PST Northwestern University researchers have invented a new high-resolution camera that can see the unseen -- including around corners and through scattering media, such as skin, fog or potentially even the human skull. |
| Posted: 17 Nov 2021 07:01 AM PST Recycling carbon dioxide, especially through conversion to methane, is compelling while anthropogenic CO2 emissions are still rising. A useful process for this transformation is photothermal methanation, in which CO2 and hydrogen are catalytically converted into CH4 and water upon irradiation with sunlight. A team of researchers has now reported the synthesis of a highly active, stable, nickel–carbon catalyst for this reaction. |
| Glass as stable as crystal: Homogeneity leads to stability Posted: 17 Nov 2021 06:59 AM PST Researchers have obtained new insights into the process of crystallization in glasses that can lead to a loss of transparency and mechanical strength. The researchers are the first to relate the coordinated atomic dynamics that lead to "devitrification" with a physical mechanism. This research may lead to improvements in the long term stability of industrial glass. |
| Artificial intelligence successfully predicts protein interactions Posted: 16 Nov 2021 02:51 PM PST Researchers used artificial intelligence (AI) and evolutionary analysis to produce 3D models of eukaryotic protein interactions. The study identified more than 100 probable protein complexes for the first time and provided structural models for more than 700 previously uncharacterized ones. Insights into the ways pairs or groups of proteins fit together to carry out cellular processes could lead to a wealth of new drug targets. |
| Finding the missing piece in global oil life-cycle assessment Posted: 16 Nov 2021 02:50 PM PST New research offers a closer look at the relationship between decreasing demand for oil and a resilient, varied oil market -- and the carbon footprint associated with both. |
| Invention lets people pay for purchases with a high-five Posted: 16 Nov 2021 02:50 PM PST Imagine your car starting the moment you get in because it recognizes the jacket you're wearing. Consider the value of a hospital gown that continuously measures and transmits a patient's vital signs. These are just two applications made possible by a new 'body area network'-enabling fabric. |
| Posted: 16 Nov 2021 12:23 PM PST Using a new model of brain activity, computational neuroscientists are exploring striking bursts of activity in the human brain that have not been examined before. These bursts may have potential to serve as biomarkers for brain disease and conditions such as depression, schizophrenia, dementia, and ADHD. |
| Game theory and economics show how to steer evolution in a better direction Posted: 16 Nov 2021 11:48 AM PST Human behavior drives the evolution of biological organisms in ways that can profoundly adversely impact human welfare. Understanding people's incentives when they do so is essential to identify policies and other strategies to improve evolutionary outcomes. In a new study, researchers bring the tools of economics and game theory to evolution management. |
| Synthetic biology yields easy-to-use underwater adhesives Posted: 16 Nov 2021 10:17 AM PST Researchers have used synthetic biology to bring together the best of spider silk and mussel foot protein in a biocompatible adhesive. |
| Making solar energy even more sustainable with light-powered technology Posted: 16 Nov 2021 10:17 AM PST Scientists have identified a new process using coordination materials that can accelerate the use of low-cost, Earth-abundant materials with the potential to transform the energy sector by replacing silicone-based solar panels. |
| A better-fitting molecular ‘belt’ for making new drugs Posted: 16 Nov 2021 10:17 AM PST The most common pharmaceuticals on the market are made by chaining together rings of molecules to create the drugs that treat conditions including pain, depression and leukemia. But creating those rings and forming them in a way that is tailored to each individual disease has always been a cumbersome and expensive process in medicinal chemistry. New research proposes a way to simplify that transformation. The discovery will likely make it easier to produce new drug candidates, the researchers say. |
| Posted: 16 Nov 2021 10:17 AM PST Turbulence makes many people uneasy or downright queasy. And it's given researchers a headache, too. Mathematicians have been trying for a century or more to understand the turbulence that arises when a flow interacts with a boundary, but a formulation has proven elusive. |
| Researchers develop rapid computer software to track pandemics as they happen Posted: 16 Nov 2021 10:15 AM PST Researchers have created lightning-fast computer software that can help nations track and analyze pandemics, like the one caused by COVID-19, before they spread like wildfire around the globe. |
| Researchers create novel molecules that serve as ziplines for energy Posted: 16 Nov 2021 08:13 AM PST Researchers have moved packets of energy along a molecular ladder made of hundreds of benzene rings. Such polymers can potentially be used to design new displays based on organic light-emitting diodes, or for solar cells. |
| Microtissue system allows study of deadly lung disease Posted: 16 Nov 2021 08:13 AM PST Amid the COVID-19 pandemic and rising air pollution levels, incidence of idiopathic pulmonary fibrosis is anticipated to rise, urgently increasing the need for strong model systems. Researchers describe a 3D cell culturing platform that allows study of lung fibroblasts and their microenvironment. The platform enables measurement of cell behaviors and microenvironment changes involved in the disease progression of IPF, and the platform's size and simplicity make it suitable for use in high-throughput drug screening protocols. |
| Electronic nose on a drone sniffs out wastewater treatment plant stink Posted: 16 Nov 2021 08:13 AM PST Researchers have engineered a portable electronic nose (e-nose) that's almost as sharp as a human nose at sniffing out the stink of wastewater treatment plants. Coupled with a drone, the lightweight e-nose can measure the concentration of different smells, predict odor intensity, and produce a real-time odor map of the plant for management. |
| A nanoantenna for long-distance, ultra-secure communication Posted: 16 Nov 2021 07:31 AM PST Researchers have used a nanoantenna to focus light onto a single semiconductor nanobox. This approach will enhance the utility of quantum repeater technology currently under development for advanced communication and data storage. Such technology is essential to overcoming the limitations of classical computer information for securely sharing information over long distances. |
| Solar energy with an' ironclad future' Posted: 16 Nov 2021 07:31 AM PST Solar energy plays an important role in the fight against climate change as a substitute for fossil fuels. Dye-sensitized solar cells promise to be a low-cost supplement to the photovoltaic systems we know today. Their key feature is the dye sensitizers attached to their surface. Researchers continue to improve the performance with sensitizers using iron -- a commonly available and environmentally friendly metal. |
| Astronomers team up to create new method to understand galaxy evolution Posted: 16 Nov 2021 07:31 AM PST A husband-and-wife team of astronomers joined forces for the first time in their scientific careers during the pandemic to develop a new method to look back in time and change the way we understand the history of galaxies. |
