A new study, published today in Nature Physics, has shown that it is possible to create tiny, self-powered swimming robots from three simple ingredients.
Adenovirus vaccine vectors, such as the ChAdOx1 nCov-19 construct which has risen to prominence as a major vaccine for COVID-19, may generate robust long-term immune system responses, according to scientists from the Universities of Oxford and the Cantonal Hospital St.Gallen, Switzerland.
Although a very promising solution for capturing solar energy, perovskite solar cells contain lead, which is toxic to the environment and a serious health hazard. EPFL scientists have now found a very elegant and efficient solution by adding a transparent phosphate salt that doesn't interfere with light-conversion efficiency while preventing lead from seeping into the soil in cases of solar panel failure.
To grow and multiply efficiently, bacteria must coordinate cell division with chromosome segregation. Key to this process is a protein called Nucleoid Occlusion Factor or Noc. A small and abundant molecule called Cytidine Triphosphate (CTP) is key to the functions of Noc. CTP binding enables Noc to "spread" on DNA to form a large protein complex. CTP also "switches on" the membrane-binding ability of Noc.
Black and Latinx people intensely sought information on COVID-19 and engaged in public health measures such as mask-wearing and testing due to devastating experiences during the pandemic but are still skeptical about vaccines, according to a Rutgers study.
Patients who experience long COVID have reported more than 200 symptoms across 10 organ systems, in the largest international study of 'long-haulers' to date, led by UCL scientists together with a patient-led research collaborative.
A new paper published in Nature Food offers the first comprehensive comparison of the most advanced international efforts to measure how nitrogen is managed in agriculture. Scientists from ten different research groups across the world, estimated how much nitrogen is added to croplands as fertilizer and manure, how much of the added nitrogen is harvested in crops, and how much is left over as potential environmental pollution.
In 2015, massive biomass burning events occurred in Equatorial Asia which released a large amount of carbon into the atmosphere, whose signals were captured by in-situ high-precision measurements onboard commercial passenger aircraft and a cargo ship. A simulation-based analysis with those observations estimated the fire-induced carbon emissions to be 273 Tg C for September - October 2015.
New study finds that stakeholders' sentiment toward a new CEO has a stronger effect on post succession performance than the CEO's previous experience and fit and this is more critical for new external CEOs
The psychological toll of losing a job due to COVID-19 caused many young hotel and restaurant workers to consider changing careers, according to a new study. Laid-off and fully furloughed hospitality employees reported being financially strained, depressed, socially isolated and panic stricken over the pandemic's effects, leading to increased intention to leave the industry. The intention to leave was particularly strong among women and younger workers. Furloughed workers reported somewhat less distress than laid-off workers.
A new study, published by the North American Menopause Society in the journal Menopause, found a plant-based diet rich in soy reduces moderate-to-severe hot flashes by 84%, from nearly five per day to fewer than one per day. During the 12-week study, nearly 60% of women became totally free of moderate-to-severe hot flashes. Overall hot flashes (including mild ones) decreased by 79%.
A small regulatory RNA found in many problematic bacteria, including Escherichia coli, appears to be responsible for managing the response of these bacteria to environmental stresses. Professor Charles Dozois from Institut national de la recherche scientifique (INRS) and doctoral student Hicham Bessaiah see a promising avenue for more effective treatment of antibiotic-resistant bacteria. Their results have been published in the journal PLOS Pathogens.
Shining a beam of light into potentially contaminated water samples may hold the key to real-time detection of hydrocarbons and pesticides in water. UBC Okanagan researchers are testing the use of fluorescence to monitor water quality. The results, they say, show great promise.
Repairing complex electrical appliances is time consuming and rarely cost-effective. The working group led by Prof. Dr. Karl Mandel, Professorship of Inorganic Chemistry at FAU, has now developed a smart microparticle that enables defective components in these appliances to be identified more quickly and easily by using light signals. In the long-term, this could make repairs easier and extend the operating life of devices. The results have been published in the journal 'Advanced Functional Materials'.
How neuronal circuits remodel themselves over time, especially during early development, is a major question in neurobiology. Using mice, researchers from Kyushu University have uncovered a biomolecular mechanism behind the strengthening of connections from neurons called mitral cells. The team found that the protein BMPR-2 is a key regulator of selective stabilization of neuron branching and that strengthening of a branch happens only when neural signals are transmitted.
For the first time, researchers have measured the flux variations of greenhouse gases (CO2 and CH4) in typical glacial basins in High Mountain Asia. They have discovered that rapid cryospheric retreat has made the basins strong sources of carbon with positive methane and CO2 fluxes. While this is partially offset by proglacial river runoff, the findings suggest that these variations should be considered in regional CH4 and CO2 climate change budgets.
The new research will help doctors identify, treat and prevent dangerous atrial fibrillation in patients with hypertrophic cardiomyopathy, a common heart condition.
Scientists have developed a rapid, highly accurate test to detect antibodies against the spike protein of SARS-CoV-2 in human serum, opening a new avenue for understanding the full extent of the pandemic and evaluating the effectiveness of vaccines.
Single-cell RNA sequencing has revealed a subset of cells that could provide protection from a rare, but severely debilitating and fatal, lung disease. The findings were published by Nagoya University researchers and colleagues in the European Respiratory Journal. Further research could lead to new therapeutic strategies for the disease, called idiopathic pulmonary fibrosis (IPF).
Access to high-quality public transportation can make communities more equitable by increasing access to critical opportunities such as employment, health care and healthy food, particularly for low-income individuals and people of color. A new paper published today in the Transportation Research Record identifies six broad categories of equity-advancing practices that reach beyond existing guidelines and could be widely employed by public transit agencies nationwide.
A study from Regenstrief Institute and Indiana University School of Medicine research scientists is one of the first to describe and identify patterns in the course of COVID-19 in the typically frail individuals who reside in nursing homes. Previously, little was known about how the disease has clinically affected individuals residing in nursing homes.
Silicon is a microelement that in low doses is vital for the normal development and functioning of connective tissue. Experiments showed that after only a few months of consuming water with added silicon animals developed a condition similar to silicosis (or miners lung disease).
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell cultures. It may also prove successful against corona viruses.
A new study finds resilience is a dynamic process, rather than a fixed trait - and suggests this may have significant ramifications for the business world.
