Nanotechnology news
![]() | White nanolight source for optical nanoimagingNanolight sources based on resonant excitons of plasmons near a sharp metallic nanostructure have attracted great interest in optical nanoimaging. However, the resonant phenomenon only works for one type of wavelength that resonates with plasmons. Compared to plasmonic resonance, the alternative plasmon nanofocusing method can generate a source of nanolight by propagating and compressing plasmons on a tapered metallic nanostructure, independent of wavelength, due to its reliance on propagation. In a new report on Science Advances, Takayuki Umakoshi and a research team in applied physics and chemistry in Japan generated a white nanolight source spanning across the entire visible light range through plasmon nanofocusing. Using the process, they demonstrated spectral bandgap nanoimaging of carbon nanotubes (CNTs). The experimental demonstration of the source of white nanolight will enable diverse research fields to progress toward next-generation, nanophotonic technologies. |
![]() | Nanosponges could intercept SARS-CoV-2 coronavirus infectionNanoparticles cloaked in human lung cell membranes and human immune cell membranes can attract and neutralize the SARS-CoV-2 virus in cell culture, causing the virus to lose its ability to hijack host cells and reproduce. |
![]() | Nanomaterial gives robots chameleon skinA new film made of gold nanoparticles changes color in response to any type of movement. Its unprecedented qualities could allow robots to mimic chameleons and octopi—among other futuristic applications. |
![]() | How Toxoplasma parasites glide so swiftlyIf you're a cat owner, you might have heard of Toxoplasma gondii, a protozoan that sometimes infects humans through contact with contaminated feces in litterboxes. Although harmless to most people, T. gondii can cause serious illness or death in immunocompromised individuals or fetuses of infected pregnant women. Now, researchers reporting in ACS Nano have studied how the microorganism glides so swiftly through mammalian tissues during an infection. |
![]() | New nanoparticle drug combination for atherosclerosis developedPhysicochemical cargo-switching nanoparticles (CSNP) designed by KAIST can help significantly reduce cholesterol and macrophage foam cells in arteries, which are the two main triggers for atherosclerotic plaque and inflammation. |
![]() | Energy storage using oxygen to boost battery performanceResearchers have presented a novel electrode material for advanced energy storage device that is directly charged with oxygen from the air. Professor Jeung Ku Kang's team synthesized and preserved the sub-nanometric particles of atomic cluster sizes at high mass loadings within metal-organic frameworks (MOF) by controlling the behavior of reactants at the molecular level. This new strategy ensures high performance for lithium-oxygen batteries, acclaimed as a next-generation energy storage technology and widely used in electric vehicles. |
![]() | Nanofiber masks can be sterilized multiple times without filter performance deteriorationWith the global spread of coronavirus infections, personal protective equipment, especially face masks, are receiving much attention.

Physics news
![]() | Simultaneous nodal superconductivity and broken time-reversal symmetry in CaPtAsIn the vast majority of superconducting materials, Cooper pairs have what is known as even parity, which essentially means that their wave function does not change when electrons swap spatial coordinates. Conversely, some unconventional superconductors have been found to contain odd-parity Cooper pairs. This quality makes these unconventional materials particularly promising for quantum computing applications. |
![]() | Schrödinger's cat explainedIn 1935, E. Schrödinger proposed his well-known cat thought experiment suggesting, but not explaining, how a measurement transforms the probable states of an atom into the actual state of a cat (alive or dead). Rather than applying quantum mechanics (the previous approach usually taken), I offer an out-of-the-box, logically consistent explanation using metrology (the science of physical measurement). |
![]() | A new way to study how elements mix deep inside giant planetsThere are giants among us—gas and ice giants to be specific. They orbit the same star, but their environmental conditions and chemical makeup are wildly different from those of Earth. These enormous planets—Jupiter, Saturn, Neptune and Uranus—can be seen as natural laboratories for the physics of matter at extreme temperatures and pressures. |
![]() | Experiments expose how powerful magnetic fields are generated in the aftermath of supernovaeIn a paper recently published by Physical Review Letters, a team of researchers including scientists from Lawrence Livermore National Laboratory (LLNL) detail the first quantitative measurements of the magnetic field structure of plasma filamentation driven by the Weibel instability, using a novel optical Thompson scattering technique. |
![]() | From custom-built to ready-made photonicsInformation technology continues to progress at a rapid pace. However, the growing demands of data centers have pushed electrical input-output systems to their physical limit, which has created a bottleneck. Maintaining this growth will require a shift in how we build computers. The future is optical. |
![]() | Machine learning qualitatively changes the search for new particlesThe ATLAS Collaboration at CERN is exploring novel ways to search for new phenomena. Alongside an extensive research program often inspired by specific theoretical models—ranging from quantum black holes to supersymmetry—physicists are applying new model-independent methods to broaden their searches. ATLAS has just released the first model-independent search for new particles using a novel technique called "weak supervision." |
![]() | Observation of excess events in the XENON1T dark matter experimentScientists from the international XENON collaboration, an international experimental group including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), University of Tokyo; the Institute for Cosmic Ray Research (ICRR), University of Tokyo; the Institute for Space-Earth Environmental Research (ISEE), Nagoya University; the Kobayashi-Maskawa Institute for the Origin of Particles and the Universe (KMI), Nagoya University; and the Graduate School of Science, Kobe University, announced today that data from their XENON1T, the world's most sensitive dark matter experiment, show a surprising excess of events. The scientists do not claim to have found dark matter. Instead, they have observed an unexpected rate of events, the source of which is not yet fully understood. The signature of the excess is similar to what might result from a tiny residual amount of tritium (a hydrogen atom with one proton and two neutrons), but could also be a sign of something more exciting—such as the existence of a new particle known as the solar axion or the indication of previously unknown properties of neutrinos. |
![]() | New quantum sensing technique allows high-resolution nuclear magnetic resonance spectroscopyNuclear magnetic resonance (NMR) spectroscopy is a widely used tool for chemical analysis and molecular structure recognition. Because it typically relies on the weak magnetic fields produced by a small thermal nuclear spin polarization, NMR suffers from poor sensitivity compared to other analytical techniques. A conventional NMR apparatus typically uses large sample volumes of about a milliliter—large enough to contain around a million biological cells. |
![]() | Quantum-inspired approach dramatically lowers light power needed for optical coherence tomographyResearchers have shown that a detection technology borrowed from quantum optics can be used to perform optical coherence tomography (OCT) with much lower light power than previously possible. This could greatly improve the imaging quality available from OCT used for medical imaging applications. |

![]() | New techniques improve quantum communication, entangle phononsQuantum communication—where information is sent through particles, typically entangled photons—has the potential to become the ultimate secure communication channel. Not only is it nearly impossible to eavesdrop on quantum communication, those who try will also leave evidence of their indiscretions. |
![]() | Graphics cards farm to help in search of new physics at LHCbFor the first time, data from LHCb, a major physics experiment, will be processed on a farm of GPUs. This solution is not only much cheaper, but it will help decrease the cluster size and process data at speeds up to 40 Tbit/s. The research paper has been published in Computing and Software for Big Science. |
![]() | Physicists develop a new theory for Bose-Einstein condensatesBose-Einstein condensates are often described as the fifth state of matter: At extremely low temperatures, gas atoms behave like a single particle. The exact properties of these systems are notoriously difficult to study. In the journal Physical Review Letters, physicists from Martin Luther University Halle-Wittenberg (MLU) and Ludwig Maximilian University Munich have proposed a new theory to describe these quantum systems more effectively and comprehensively. |
![]() | A step forward in solving the reactor-neutrino flux problemJoint effort of the nuclear theory group at the University of Jyvaskyla and the international collaborative EXO-200 experiment paves the way for solving the reactor antineutrino flux problems. The EXO-200 collaboration consists of researchers from 26 laboratories and the experiment is designed to measure the mass of the neutrino. As a byproduct of the calibration efforts of the experiment the electron spectral shape of the beta decay of Xe-137 could be measured. This particular decay is optimally well suited for testing a theoretical hypothesis to solve the long-standing and persistent reactor antineutrino anomaly. The results of measurements of the spectral shape were published in Physical Review Letters in June 2020. |
![]() | A proven method for stabilizing efforts to bring fusion power to EarthAll efforts to replicate in tokamak fusion facilities the fusion energy that powers the sun and stars must cope with a constant problem—transient heat bursts that can halt fusion reactions and damage the doughnut-shaped tokamaks. These bursts, called edge localized modes (ELMs), occur at the edge of hot, charged plasma gas when it kicks into high gear to fuel fusion reactions. |

![]() | Stocks of vulnerable carbon twice as high where permafrost subsidence is factored inNew research from a team at Northern Arizona University suggests that subsidence, gradually sinking terrain caused by the loss of ice and soil mass in permafrost, is causing deeper thaw than previously thought and making vulnerable twice as much carbon as estimates that don't account for this shifting ground. These findings, published this week in the Journal of Geophysical Research: Biogeosciences, suggest traditional methods of permafrost thaw measurement underestimate the amount of previously-frozen carbon unlocked from warming permafrost by over 100 percent. |

![]() | Wind farms 'turn off times' could help save Eastern European bat populationsThe Via Pontica, an important migration route for birds in Eastern Europe, runs along the Black Sea coast of Romania and Bulgaria. Bats also use this route. In this region, numerous wind farms have been installed in recent years because of good wind conditions, but there has been little implementation of the legally required measures for the protection of bats. A Romanian research team cooperated with the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Berlin to demonstrate that this leads to high death rates of migrating bats and potentially large declines even in populations living far away in other countries. The scientists therefore recommend the widespread introduction of turn-off times during the migration months, which—as the team was able to show in a local wind farm—would massively decrease bat mortality yet produce only a marginal loss in the energy production of the turbines. |

![]() | New family of enzymes reveals the Achilles' heel of fungal pathogensAspergillus fumigatus is a species of fungus that can cause serious illnesses in immunocompromised individuals such as those who are undergoing transplantation or cancer chemotherapy. Every year, about 500,000 new Aspergillus cases are reported, and even with antifungal agents in place, the mortality rate remains over 50%. Infections caused by A. fumigatus are difficult to treat because during an infection, the fungus aggregates into small communities called "biofilms." These biofilms not only protect the pathogens from antifungal agents, but also help the fungus evade the immune system. Researchers around the world have been trying to understand how biofilms are produced and how they can be disrupted, as this knowledge will be crucial for developing effective therapeutics. |

![]() | A fair reward ensures a good memory, study revealsHow does our memory work, and how can we optimize its mechanisms on a daily basis? These questions are at the heart of many neuroscience research projects. Among the brain structures examined to better understand memory mechanisms, the reward system is now at the center of investigations. Through the examination of brain activity in healthy human subjects, scientists from the University of Geneva (UNIGE) have highlighted the lasting positive effect of a reward—monetary, in this case—on the ability of individuals to retain a variety of information. Moreover, and much more surprisingly, the research team demonstrated that the average accumulation of reward should be neither too small nor too large. By ensuring an effective neural dialog between the reward circuit and the memory circuit, this delicate balance allows the proper encoding of memories in our brain. These results can be read in Nature Communications. |

![]() | Early and intensive treatment of rheumatoid arthritis reduces fatigueDisease-related, profound fatigue impairs the quality of life of many people with rheumatic and musculoskeletal diseases. A Belgian study has now concluded that early intensive treatment combining methotrexate with a bridging scheme of prednisone can reduce the onerous fatigue—this also applies to patients at low risk of a severe course. The European League against Rheumatism (EULAR) therefore recommends, that even in so-called low-risk patients, early consideration should be given to whether intensive treatment should be initiated. |
![]() | Call for caution for using a CAR-T immunotherapy against acute myeloid leukemiaAcute myeloid leukemia (AML) is a hematological malignancy the incidence of which increases with age, that is biologically, phenotypically, and genetically very heterogeneous. Its treatment combines chemotherapy followed by allogenic Hematopoietic Stem and Progenitor Cells transplant (allo-HSCT), based on the patient's eligibility, to consolidate complete remission and prevent relapse. Yet, except for a few subgroups, so-called low-risk AMLs, relapses are frequent after consolidation therapy and transplant. Chemotherapy-related toxicity, refractoriness, and failure to eradicate leukemia-initiating cells are the major causes underlying AML progression and relapse. Unfortunately, improved AML treatments have only experienced minor developments over the last four decades, and current 5-year event-free survival remains in a 20% in adults and less than 70% in children, highlighting the desperate need for safer and more efficient therapeutics. |

![]() | New study suggests that hard eggshells evolved at least three times in dinosaur family treeNew research suggests that the first dinosaurs laid soft-shelled eggs—a finding that contradicts established thought. The study, led by the American Museum of Natural History and Yale University and published today in the journal Nature, applied a suite of sophisticated geochemical methods to analyze the eggs of two vastly different non-avian dinosaurs and found that they resembled those of turtles in their microstructure, composition, and mechanical properties. The research also suggests that hard-shelled eggs evolved at least three times independently in the dinosaur family tree. |

![]() | Envy divides societyIt's generally recognized that differences in background and education cement class differences. It is less clear when and under what circumstances individual psychological forces can drive an initially homogenous social group apart and ultimately divide it. Claudius Gros, professor for theoretical physics at Goethe University, investigated this question in a mathematical precise way using game theory methods. "In the study, societies of agents—acting individuals—are simulated within game theory, which means that everybody optimizes her/his success according to predetermined rules. I wanted to find out whether social differences can emerge on their own if no one starts off with advantages—that is, when all actors have the same skills and opportunity," the physicist explains. |
